The PVC material shall have a minimum cell classification of 12454, 13343 or 12364 as defined in ASTM D 1784. 2.0 The purpose of GPK in-line fittings is to convey municipal sanitary and industrial wastes, storm water runoff and many other related applications. They are designed to be used in gravity flow and low pressure applications not to exceed 10.8 psi. (74.5 kPa). 3.0 Injection Molded Fittings are produced in sizes 4â€ (100mm) through 12â€ (300mm) diameter. Fabricated Fittings are produced in sizes 4â€ (100mm) through 36â€ (973mm) diameter. A fabricated fitting is considered any fitting made from pipe or a combination of pipe and molded components. 4.0 Chemical Resistance GPK fittings resist attack from certain alcohols, alkalies, salt solutions, acids and other types of chemicals. Refer to chemical resistant chart for suitability. 5.0 Marking. GPK fittings shall be marked with applicable size, â€œPVCâ€, company name or logo, PSM and the ASTM specification number (D 3034, F 1336 or F679). The fittings and/or packaging shall include the manufacturerâ€™s date and shIft code. 6.0 Testing. A test after installation of either low pressure air (Uni-B-6) or a water infiltration-exfiltration test is recommended. 7.0 Deflection Test. The maximum allowable pipe fitting deflection should be 7 Â½% of base ID as shown in table X1.1 of D 3034, and X2.1 of F 679. 8.0 Backfilling and Tamping. Backfilling should follow closely after assembly of pipe and fittings. 8.1 Backfilling. with proper material is important to achieve desired density in haunching area which enables pipe, fitting and soil to work together to meet designed load requirements. This eliminates excess deflection and shear breaks due to heavy loads. Approved material shall be used properly, compacted continuously above and around the pipe and fittings as well as between fitting and trench wall. A cushion of approved material up to a minimum of 12â€ (305mm) over the fittings and between the trench walls shall be applied in accordance with the engineersâ€™ specifications. 8.2 Tamping. This shall be done by hand tamping of the embedment material between the trench wall of the service line fitting and riser connection. Tamping can also be done by mechanical tampers or by using water to consolidate the embedment material. Extreme unstable ground conditions may require wider trenches to enable you to compact a larger area around the pipe and fittings to the density consistent of the original ground surface conditions. 9.0 Service Lines. Normally, service lines from the property line to the collection sewer should be a minimum depth of 3 feet (1 meter) at the property line and should be laid in straight alignment and uniform slope of not less than Â¼â€ per foot (20.8mm/meter) for 4â€ (100mm) nominal pipe and 1/8â€ (10.4mm/meter) per foot for 6â€ (150mm) pipe. Where collection sewers are deeper than 7 feet (2 meters) a vertical standpipe or stack is permitted but not recommended, consult the project engineer for proper installation details. Deep sewer chimney and risers necessitate extreme care during backfilling. Where surface loading is anticipated the final backfill must be compacted to a density compatible with those surface loads to be encountered. 9.1 Backfilling around pipe service laterals on slope. Extra attention should be given on slopes to prevent the newly backfilled trench from becoming a â€œFrench Drainâ€. Before backfilling completely there is a tendency for ground and surface water to follow the direction of the looser soil. This flow may wash out soil from under or around pipe and branch line fittings, reducing or eliminating the support needed. To avoid this problem the backfilling should be of greater compaction. Tamping should be done in 4â€ (100mm) layers and continued in this manner all the way up to the ground or surface line of the trench. Concrete collars or other concrete poured around the fitting to stabilize unwanted movement is recommended to prevent water from undercutting the underside of the pipe and fittings. Summary: Due to various ground conditions and different situations, installation techniques vary widely. We warranty our products to be free of manufacturerâ€™s defects. We will not replace the products that are installed or used incorrectly. The design of the systems that our product is used in is a factor that cannot be overlooked. 811 1 GPK FITTING SUBMITTAL SHEET Intro: GPK manufactures PVC sewer fittings in accordance with either ASTM D 3034, F 1336 or F 679 to be used in gravity flow or low pressure applications.

No Lubricant Needed The RFS Prelubricated Gasket has all the lubricant it needs in- side the sealed mantle. Joints slide together quickly and easily. Step 2 Center pipe spigot and bell, and evenly and smoothly press spigot into bell. Gasket mantle will help center the pipe joint as the mantle moves into clearance space. Self-Centering Design The RFS Prelubricated Gasket requires no equalization. It au- tomatically adjusts during application and then helps center the joint during assembly. Step 3 Complete assembly until pipe joint is home. Mantle moves into recess be- hind gasket, cushioning the joint while allowing joint to deflect. Complete installation by following pipe manu- facturerâ€™s recommended bedding and backfilling practices. Press-Seal believes all information is accurate as of its publication date.

Using a precision extrusion, the gasket is spliced, tested and filled with an internal lubricant that doesnâ€™t solidify or need to be replaced. The RFS design allows concrete pipe joints to be assem- bled quickly and easily. How It Works RFS Prelubricated Pipe Gaskets have superior materials and technology. â€¢ Specially developed synthetic rubber is continuously tested and lab-certified for concrete pipe joints conforming to ASTM C-443. â€¢ RFS is easy to apply to the spigot of the pipe and requires no equalization. â€¢ RFS helps center the pipe during assembly and this reduces joint homing forces. â€¢ The mantle of the RFS Gasket fits into the concrete annular space, limiting differential settlement. â€¢ Special viscosity silicone lubricant to reduce joint homing forces. Why Itâ€™s Better How It Performs RFS Prelubricated Pipe Gaskets meet or exceed â€¢ Installs easily and neatly on the pipe spigot all requirements of the following Specifications and/or â€¢ Reduces dependency on manpower to properly Test Methods: prepare joint for assembly. â€¢ Requires no external lubrication or equalization ASTM C 1619 (Classes C) - Standard Specification â€¢ Installs faster and easier, so less time in the ditch for Elastomeric Seals for Joining Concrete Structures â€¢ Requires no external lubricant, so pipe joint stays cleaner during handling and assembly ASTM C 443 - Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets CSA A 257.3 - Gaskets for Concrete Pipe Scan (or click) Here To View More Info On This Product On The Web!

Boots are too flexible and grade control becomes difficult. The pipes move too much to match the invert channel in the manhole, creating problems in the flow line. When GPK Sanded Manhole Adapters are set in the manhole base, grade control is set in concrete and will not vary from the specifications. --Panhandle Concrete Products, Inc. - Post Falls, Idaho One contractor estimated that there was a savings of 20 minutes per manhole in crew time installing manholes with GPK Sanded Manhole Adapters versus manholes with boots. Also, when the pipe was set into the GPK Sanded Manhole Adapter, that was it, the job was totally done. --Panhandle Concrete Products, Inc.

Hg for zero infiltration of groundwater. This design also allows for compression and low insertion pressures during installation. The smooth inner wall of the PVC sleeve provides optimum flow conditions, and the exteriorâ€™s abrasive silica layer allows grout to bond the adapter to the concrete manhole. Each contractor I work with expresses great satisfaction and preference for GPK Sanded Manhole Adapters versus boots. They believe that a manhole base constructed with GPK Sanded Manhole Adapters is a higher quality product and faster to install. --Panhandle Concrete Products, Inc. Post Falls, Idaho Uncompromising Strength North Dakota State University, located in Fargo, ND is renowned for its elite research institutions in many fields. When NDSU scientists and research graduates conducted testing of the GPK PVC Manhole Adapter, they found that the system bonded so strongly that over 3 tons psi was required to break the adapter. Overall, NDSU research professionals found that GPK Manhole Adapters, installed using the proper conventional methods, are superior overall because of their ease of installation, strength, flexibility and lifetime guarantee. 1601 43rd Street N â€¢ Fargo, ND 58102 1601 43rd Street N â€¢ Fargo, ND 58102 Toll Free: 800-437-4670 â€¢ Fax: 800-822-6989 Toll Free: 800-437-4670 â€¢ Fax: 800-822-6989 SDR35 D 3034 / PS46 F 679 FITTING SPECIFICATIONS 1.0 GPK PVC Sewer Fittings shall be manufactured in accordance with either ASTM D 3034, F1336 or F 679. The PVC material shall have a minimum cell classification of 12454, 13343 or 12364 as defined in ASTM D 1784. 2.0 The purpose of GPK in-line fittings is to convey municipal sanitary and industrial wastes, storm water runoff and many other related applications. They are designed to be used in gravity flow and low pressure applications not to exceed 10.8 psi. (74.5 kPa). 3.0 Injection Molded Fittings are produced in sizes 4â€ (100mm) through 12â€ (300mm) diameter. Fabricated Fittings are produced in sizes 4â€ (100mm) through 36â€ (973mm) diameter. A fabricated fitting is considered any fitting made from pipe or a combination of pipe and molded components. 4.0 Chemical Resistance GPK fittings resist attack from certain alcohols, alkalies, salt solutions, acids and other types of chemicals. Refer to chemical resistant chart for suitability. 5.0 Marking. GPK fittings shall be marked with applicable size, â€œPVCâ€, company name or logo, PSM and the ASTM specification number (D 3034, F 1336 or F679). The fittings and/or packaging shall include the manufacturerâ€™s date and shIft code. 6.0 Testing. A test after installation of either low pressure air (Uni-B-6) or a water infiltration-exfiltration test is recommended. 7.0 Deflection Test. The maximum allowable pipe fitting deflection should be 7 Â½% of base ID as shown in table X1.1 of D 3034, and X2.1 of F 679. 8.0 Backfilling and Tamping. Backfilling should follow closely after assembly of pipe and fittings. 8.1 Backfilling. with proper material is important to achieve desired density in haunching area which enables pipe, fitting and soil to work together to meet designed load requirements. This eliminates excess deflection and shear breaks due to heavy loads. Approved material shall be used properly, compacted continuously above and around the pipe and fittings as well as between fitting and trench wall. A cushion of approved material up to a minimum of 12â€ (305mm) over the fittings and between the trench walls shall be applied in accordance with the engineersâ€™ specifications. 8.2 Tamping. This shall be done by hand tamping of the embedment material between the trench wall of the service line fitting and riser connection. Tamping can also be done by mechanical tampers or by using water to consolidate the embedment material. Extreme unstable ground conditions may require wider trenches to enable you to compact a larger area around the pipe and fittings to the density consistent of the original ground surface conditions. 9.0 Service Lines. Normally, service lines from the property line to the collection sewer should be a minimum depth of 3 feet (1 meter) at the property line and should be laid in straight alignment and uniform slope of not less than Â¼â€ per foot (20.8mm/meter) for 4â€ (100mm) nominal pipe and 1/8â€ (10.4mm/meter) per foot for 6â€ (150mm) pipe. Where collection sewers are deeper than 7 feet (2 meters) a vertical standpipe or stack is permitted but not recommended, consult the project engineer for proper installation details. Deep sewer chimney and risers necessitate extreme care during backfilling. Where surface loading is anticipated the final backfill must be compacted to a density compatible with those surface loads to be encountered. 9.1 Backfilling around pipe service laterals on slope. Extra attention should be given on slopes to prevent the newly backfilled trench from becoming a â€œFrench Drainâ€. Before backfilling completely there is a tendency for ground and surface water to follow the direction of the looser soil. This flow may wash out soil from under or around pipe and branch line fittings, reducing or eliminating the support needed. To avoid this problem the backfilling should be of greater compaction. Tamping should be done in 4â€ (100mm) layers and continued in this manner all the way up to the ground or surface line of the trench. Concrete collars or other concrete poured around the fitting to stabilize unwanted movement is recommended to prevent water from undercutting the underside of the pipe and fittings. Summary: Due to various ground conditions and different situations, installation techniques vary widely. We warranty our products to be free of manufacturerâ€™s defects. We will not replace the products that are installed or used incorrectly. The design of the systems that our product is used in is a factor that cannot be overlooked. 811 1 GPK FITTING SUBMITTAL SHEET Intro: GPK manufactures PVC sewer fittings in accordance with either ASTM D 3034, F 1336 or F 679 to be used in gravity flow or low pressure applications.

No Lubricant Needed The RFS Prelubricated Gasket has all the lubricant it needs in- side the sealed mantle. Joints slide together quickly and easily. Step 2 Center pipe spigot and bell, and evenly and smoothly press spigot into bell. Gasket mantle will help center the pipe joint as the mantle moves into clearance space. Self-Centering Design The RFS Prelubricated Gasket requires no equalization. It au- tomatically adjusts during application and then helps center the joint during assembly. Step 3 Complete assembly until pipe joint is home. Mantle moves into recess be- hind gasket, cushioning the joint while allowing joint to deflect. Complete installation by following pipe manu- facturerâ€™s recommended bedding and backfilling practices. Press-Seal believes all information is accurate as of its publication date.

Using a precision extrusion, the gasket is spliced, tested and filled with an internal lubricant that doesnâ€™t solidify or need to be replaced. The RFS design allows concrete pipe joints to be assem- bled quickly and easily. How It Works RFS Prelubricated Pipe Gaskets have superior materials and technology. â€¢ Specially developed synthetic rubber is continuously tested and lab-certified for concrete pipe joints conforming to ASTM C-443. â€¢ RFS is easy to apply to the spigot of the pipe and requires no equalization. â€¢ RFS helps center the pipe during assembly and this reduces joint homing forces. â€¢ The mantle of the RFS Gasket fits into the concrete annular space, limiting differential settlement. â€¢ Special viscosity silicone lubricant to reduce joint homing forces. Why Itâ€™s Better How It Performs RFS Prelubricated Pipe Gaskets meet or exceed â€¢ Installs easily and neatly on the pipe spigot all requirements of the following Specifications and/or â€¢ Reduces dependency on manpower to properly Test Methods: prepare joint for assembly. â€¢ Requires no external lubrication or equalization ASTM C 1619 (Classes C) - Standard Specification â€¢ Installs faster and easier, so less time in the ditch for Elastomeric Seals for Joining Concrete Structures â€¢ Requires no external lubricant, so pipe joint stays cleaner during handling and assembly ASTM C 443 - Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets CSA A 257.3 - Gaskets for Concrete Pipe Scan (or click) Here To View More Info On This Product On The Web!

NO. 09-01-03 S-140C SPECIFICATIONS OTHER SIDE September 1, 2003 SPECIFICATIONS SERIES 140C COMBINATION AIR VALVES Combination Air Valve (single body, double orifice) allows large volumes of air to escape out the larger diameter air vacuum orifice when filling a pipeline and closes water tight when the liquid enters the valve. During large orifice closure, the smaller diameter air release orifice will open to allow small pockets of air to escape automatically and independently of the large orifice. The large air & vacuum orifice shall also allow large volumes of air to enter through the orifice during pipeline drainage to break the vacuum. The body inlet must be baffled to protect the lower float from direct contact of the rushing air and water to prevent premature valve shut-off. The top large orifice plug must be protected in similar manner for the same purpose. The Buna-N seat must be fastened to the valve cover without distortion, for drop tight shut-off. The float shall be heavy stainless steel, hermetically sealed, designed to withstand a minimum of 1000 psi (static). The top plug shall be center guided thru hex bushings for positive shut-off. Valve exterior to be painted Universal Primer for high resistance to corrosion. The cross sectional area of the discharge orifice must be equal to the cross sectional area of the valve inlet size. All materials of construction shall be certified in writing to conform to A.S.T.M. specifications as follows: Body & Cover Cast iron ASTM A126 Gr.B Float* Stainless Steel ASTM A240 T304 Needle & Seat Buna-N Plug Brass ASTM B124 Leverage Frame [1â€&2â€] Delrin ASTM D4181 [3â€&4â€] Cast iron ASTM A126 Gr.

From our discussion, it does not look like they are going to be able to put in ADA compliant ramps per plan without reconstructing Alcazar. Itâ€™s looking like they will need to do a maximum extent feasibility study for that intersection. Attached are the files included in the email chain below. Gary, Also attached is an example of what the city requires for an MEF (The word and excel files). MEF_Example is for two non-compliant ramps at Macleod & 5th. This is just an example for your information. The only issue they had on that site was the slope of the ramps, and the example does not include all of the documetation that will be required for the issues on Alcazar detailed below. All of the non-conformance issues identified in the email chain below must be addressed in the submittal, not just the non-compliant slopes of the landing areas of the ramps. If you have any questions, let me know. Please submit the full package to ced@arlingtonwa.gov for review once complete.

They mentioned to me that they thought that at least one of the ADA ramps at the intersection of the southern alley into the development and Alcazar meets ADA requirements due to the length of the ramp. If you have not seen the attached photos and the email below, please take a look. The plans call out ADA ramps per the WSDOT standard plan, which do not allow for the maximum slopes to be exceeded for any reason. It does not look like the ramps are going to fit per the WSDOT standard plan where they are located now. We cannot accept ramps that exceed the maximum slopes without going through a maximum extent feasibility study for our documentation. Are there plan changes that are coming on this, or is there a different plan for this intersection moving forward? Thanks, Brian Grieve City of Arlington CED Inspector (360) 913-1396 From: Brian Grieve <bgrieve@arlingtonwa.gov> Sent: Wednesday, July 14, 2021 9:06 AM To: Dan Kitchen <DKitchen@ccedwardsconstruction.com> Cc: Nova Heaton <NHeaton@arlingtonwa.gov>; Kevin Olander <kolander@arlingtonwa.gov>; Brian Grieve <bgrieve@arlingtonwa.gov> Subject: ADA Ramps Alcazar/Alley Dan, There are a few issues with the ADA ramps at the intersection of Alcazar and the southern alley into the development. 1. Neither of the ADA ramps meet the maximum slope requirements. The landing areas in the attached photos are almost 8%, and the maximum allowable is 2%. 2. The ramps are missing the raised curb sections that have been highlighted in the attached standard plan. 3. There is no separation between the driveway for building 1 on the north side of the alley and the north ADA ramp. The depressed portion of the driveway transfers directly into the ADA ramp. The southern wing of the building 1 driveway cannot be used as the ramp portion of the north ADA ramp. Considering the slope of the Alcazar, I think it is going to be difficult to achieve the maximum allowable slope on those ADA ramps located where they are. Please go out there and take a look at the ramps and let me know what you think. If those pedestrian ramps donâ€™t fit in there within the maximum slopes, that crossing may need to be shifted up the alley to the east where the grade across the roadway isnâ€™t so steep. Let me know if you have any questions.

Kevin and I have been in discussions about that cut slope, and are in agreement with removing the trees, regrading the slope, and replanting the trees on the stabilized slope. (Benching might be necessary to give the new trees a solid footing.) Please continue working with Kevin on this issue. Regarding the rest of the geotechnical report and the reduction to the buffer, I am not really comfortable with the proposal. We had a solid geotechnical evaluation that established those buffers and outlined site specific geotechnical evaluations for any foundation that encroaches into those lines. I am not comfortable reducing those buffers based on a 2 page memo. I think each of the buildings identified as encroaching into the setback buffer still need to be evaluated on site as described in the approved report by Associated Earth Sciences, INC, page 11 under 5.3. â€œTownhomes that encroach on the minimum slope buffer zone would require individual engineering evaluation on a case-by-case basis.â€ I have one other coordination issue for you, regarding access down to the field for cut and harvest. Can you work with our contact and provide him a rough roadway through the site to the access road down if there isnâ€™t one currently? His name is John Tillman and his number is 360-618-2763. This requires about 1 week to cut and will need to be done about 3 to 4 times during the cutting season. The work is very weather dependent, so itâ€™s difficult to know exactly when they would require access and would need to coordinate closely with your team. They would need access down each morning with their large equipment and back up each night during the week of cutting.

I spoke with Marc and he indicated that we will be phasing out the civil review accordingly. We received the check for $35,618.40 for the Phase 1 fees, however upon taking a closer look at the Construction Calculation Worksheet that was submitted, it looks like the formulas were not calculating correctly. Iâ€™ve attached the original submitted version (6.12.20 _GW Phase 1 Construction Calculation Worksheet) and a revised version showing the corrected formulas and fees (RJ Revisedâ€¦). We found that the formulas werenâ€™t populating correctly due to additional lines being added to the spreadsheet, which in turn pushed the formulas out of cell order. We were able to correct the formulas accordingly, however the fees did change within the plan review and Assurance Device fields along with the correction. See below for plan review fee breakdown: Plan Review Fee: $980,792.50 x 6% = $58,847.55 Amount received via check: $35,618.40 $58,847.55 - $35,618.40 = $23,229.15 Plan Review Fee Remaining Amount Due: $23,229.15 If you would like we can certainly go ahead and process the check that was received for the $35,618.40 if you would like to issue an additional check for the remaining fees. Please advise if you would prefer to handle that differently. We have not verified the remaining calculation worksheets but we will be reviewing them and will of course reach out when we have done so. Please feel free to reach out should you have any questions, or I am available to discuss over the phone if you would like as well. Thank you!

PROJECT OVERVIEW The Gilman Walk at Country Charm project site consists of one parcel with a total area 21.22 acres and is located in Snohomish County within the City of Arlington. More specifically, the site is located in SW quarter of Section 1, Township 31, Range 5 East, W.M., just east of Alcazar Avenue and north of Park Hill Drive. The site is bound by single family residences to the south and Alcazar Avenue to the west. North and east of the project site is city property that is within the floodplain for the Stillaguamish River. The project site currently contains a paved access road with a barn on the west side of the site and a single family residence on the east side of the site. The rest of the site is covered in grass and gravel with trees covering the slopes along the north and east property lines. See Figure 1.1 at the end of this section for a vicinity map. The King County tax parcel ID numbers for the project site is located in Table 1.1 below. (Refer to the King County parcel reports included at the end of this section). Table 1.1 Snohomish County Parcel ID Parcel # Parcel Area (acres) 31050100302200 21.22 31050100300200 0.18 Total: 21.40 The property is located entirely within the Stillaguamish River Basin. Refer to Section 3 of this report for a description of the offsite analysis. Steep slopes exist on the north and east property lines, sloping away from the site. The rest of the site slopes generally to the north at slight to moderate grades. The proposed development will include multiple duplex, triplex and four-plex structures that will contain up to a total of 115 units with associated roads and utilities. The project will connect to E Gilman Avenue and E Division Street at the west property line near the southwest corner of the site. The project is located within the City of Arlington and is subject to the requirements presented in the 2012 Stormwater Management Manual for Western Washington (SMMWW) as amended in 2014. The drainage analysis for detention sizing has been modeled using the MGS Flood modeling program, an approved model per the manual. Core Design, Inc.

CONDITIONS AND REQUIREMENTS SUMMARY The project will be designed using the guidelines and requirements established in the 2014 SMMWW. This is a multifamily residential project which proposes greater than 5,000 square feet of new hard surface area, therefore requiring the project to demonstrate compliance with all nine (9) minimum requirements. 2.1 Minimum Requirements 2.1.1 Minimum Requirement #1: Preparation of Stormwater Site Plans Civil Plans under separate cover and a Final Storm Drainage Report herein have been prepared for the subject project. 2.1.2 Minimum Requirement #2: Construction Stormwater Pollution Prevention All 12 elements to be addressed. A Temporary Erosion and Sediment Control (TESC) plan has been included with the Civil Plans and a SWPPP has been provided under separate cover. 2.1.3 Minimum Requirement #3: Source Control of Pollution This minimum requirement applies to the construction activities for this project. The BMPs proposed are shown on the TESC plans and described in the SWPPPP report, both of which have been provided under separate cover. 2.1.4 Minimum Requirement #4: Preservation of Natural Drainage Systems and Outfalls Discharge from the site is to the existing natural discharge location which is the undeveloped land north of the site that drains to the Stillaguamish River. 2.1.5 Minimum Requirements #5: On-site Stormwater Management Stormwater BMP design is discussed in Section 4.1 of this report. The required BMPs are determined using the flow chart in Figure 4.1 in Section 4.1 of this report. 2.1.6 Minimum Requirement #6: Runoff Treatment The project is a multi-family residential project and therefore is required to provide enhanced water quality treatment. The project proposes to regrade the existing pond in order to provide enhanced treatment for stormwater runoff. The pond will meet the requirements for a Stormwater Treatment Wetland. Designs for the treatment facilities are described in Section 4 of this report. 2.1.7 Minimum Requirement #7: Flow Control Flow control is addressed in Section 4 of this report. The project proposes to discharge directly to a flow control-exempt surface water and is therefore not required to provide a flow control facility. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 2-1 2.1.8 Minimum Requirement #8: Wetland Protection There is wetland area offsite to the north of the project. The project proposes to convey stormwater runoff outside of the wetland area and its buffer and into the existing pond. Therefore, the project will have no effect on the wetland or its buffer. 2.1.9 Minimum Requirement #9: Operation and Maintenance This minimum requirement is addressed in Section 10 of this report. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 2-2 SECTION 3. OFFSITE ANALYSIS A level 1 downstream analysis was performed on the project site. All related tasks are addressed below. TASK 1 Study Area Definition and Maps The proposed project contains parcel numbers 31050100302200 and 31050100300200. Refer to the property report located at the end of Section 1. TASK 2 Resource Review Basin Reconnaissance Summary Reports No Basin Reconnaissance Summary Reports appear to be available for the area that is within one mile of this project site. FEMA Maps A FEMA map dated November 8, 1999 number 53061C0405E was reviewed. The developable site is not located within a floodplain as it is covered by â€œZone X â€“ Outside of 500-year floodplainâ€. The FEMA Map is included at the end of this section. USDA Natural Resources Conservation Service Soil Survey The USDA Natural Resources Conservation Service (NRCS) Web Soil Survey covers the project site area. The Soils Map exhibit is included at the end of this section. TASK 3 Field Investigation Tributary Area The entire site generally slopes toward the north. The eastern third of the project site slopes towards the property boundary to the north and east. Steep slopes exist at the north and east property lines towards the country charm conservation area. Upstream Tributary Analysis A small amount of upstream drainage is tributary to the project site from a mostly undeveloped neighboring parcel at the south property line. TASK 4 Drainage System Description and Problem Description A downstream analysis was performed on Thursday October 10th, 2019. The weather was sunny and approximately 55 degrees. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 3-1 A Level 1 downstream analysis was performed on the project site. The site is currently partially developed with a barn structure at the southwest corner of the site and a residential structure at the northeast corner. A paved road accesses the site at the west property line connecting to East Gilman Avenue and continues through the project site to the northeast corner. Much of the site adjacent to the roadway is covered in grass and gravel with a pit containing concrete rubble in one area. The rest of the site is covered in trees. The entire site is located within the Stillaguamish River drainage basin. The majority of the site generally slopes to the north with north facing steep slopes at the north and south property lines. At the northeast corner of the site, the existing ground slopes steeply to the north and to the east towards the property lines and continues offsite. Immediately offsite to the north and east is the Country Charm Conservation area which is undeveloped and part on the floodplain for the Stillaguamish River. An existing pond is located offsite just north of the project. The Country Charm Conservation area is flat and is entirely tributary to the South Fork Stillaguamish River. Due to the existing slopes on site, stormwater runoff leaves the site in two direction, north and east. North Discharge: Stormwater runoff from a majority of the site flows to the north until reaching the steep slopes along the north property line. There is a manmade ditch along the north property line at the foot of the steep slopes that intercepts runoff and directs stormwater west, eventually discharging into the South Fork of the Stillaguamish River. The overflow route for the pond is the manmade ditch. The ditch carries stormwater approximately 1,500 feet from the pond to the South Fork Stillaguamish River. East Discharge: Area near the east property line slopes towards the east down the existing steep slopes. Just east of the site is another existing pond that detains stormwater. Runoff leaves this pond through a creek that flows to the north. The creek flows north for approximately Â½-mile before entering the South Fork Stillaguamish River. In summary, both discharge locations converge at a point less than Â¼-mile downstream of the project site in the Stillaguamish River, and is therefore considered a single basin. Refer to Figure 4-1: Existing Conditions Exhibit and Figure 4.2: Developed Conditions Exhibit in Section 4 for the basin map. Core Design, Inc.

FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN 4.1 Project LID Feasibility Per Minimum Requirement #5, the project shall implement on-site stormwater management BMPs in accordance with the 2014 SMMWW. The flow chart below is used to determine the BMP requirements for the project. Figure 4.1: Flow Chart for Determining LID MR #5 Requirements Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-1 This project directly discharges to the South Fork Stillaguamish River, a flow control exempt surface water per Minimum Requirement #7. Therefore the project is not required to meet the LID Performance Standard, or apply the BMPs from list #1 and #2 of Section 1-2.5.5 of the 2014 SMMWW. The project will implement the following BMPs where feasible as required by Figure 4.1 above: â€¢ BMP T5.13: Post-Construction Soil Quality and Depth Response: This BMP will be implemented for all lawn and landscaped areas that are affected by construction and grading activities in accordance with BMP T5.13 in the 2014 SMMWW. â€¢ BMP T5.10A: Downspout Full Infiltration Response: The soils on-site do not support infiltration facilities as determined by a geotechnical engineer, therefore the BMP is not applicable. Refer to the Geotechnical Report submitted under separate cover. â€¢ BMPT5.10B: Downspout Dispersion Systems Response: The project site cannot support the required flowpath for full dispersion due to site constraints. This BMP is not applicable. â€¢ BMP T5.10C: Perforated Stub-out Connections Response: Perforated stub-out connections will be implemented wherever feasible per a geotechnical review. â€¢ BMP T5.11: Concentrated Flow Dispersion Response: Due to the steep slopes located on site, the project cannot support the required vegetated flow path for Concentrated Flow Dispersion. â€¢ BMP T5.12: Sheet Flow Dispersion Response: Sheet flow dispersion is proposed for areas that can support the required flow path, such as the proposed trail. 4.2 Hydraulic Analysis All stormwater facilities will be designed in accordance with the 2014 SMMWW. The drainage analysis for detention and water quality sizing was modeled using the MGS Flood modeling program. 4.2.1 Existing Conditions The 21.40-acre project site contains two single family structures with several barns located on site. A paved access road, Gilman Avenue, provides access to the site and continues across the site to the Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-2 northeast. The rest of the site contains gravel and trees, with steep slopes along the north and east property lines. The predeveloped condition has been modeled using historic site conditions. Table 4-1 below shows that the entire site has been modeled as Forested using the MGS Flood software. Only areas that are subject to grading activities in the developed condition are considered in the predeveloped condition. A total of 13.66 acres of the 21.40 acre site is included in the developed basin. Critical areas and forested area that is not proposed to be cleared are left out of the predeveloped basin. Table 4-1 Predeveloped Areas GROUND COVER TOTAL (acres) Forested 13.66 Refer to the MGS Flood report located in the Appendix. 4.2.2 Developed Conditions The project proposes the construction of multi-family residential structures with associated roads and utilities. Access to the site will be provided by a proposed roadway that will connect to East Gilman Avenue at the west property line. The project is exempt from providing a flow control facility per Minimum Requirement #7 as the project can discharge directly to the Stillaguamish River, which is listed as a flow control exempt surface water in Table I-E.1 Exempt Surface Waters List in the 2014 SMMWW. The project will collect and convey stormwater runoff to an existing pond north of the project site that will be regraded and used for water quality purposes. Refer to Section 4.4 for more information on runoff treatment. This discharge point also matches the natural discharge location for the existing site, meeting Minimum Requirement #4. Table 4-2 below shows the areas proposed as part of this project. Also refer to the Developed Conditions Exhibit for a visual of these on-site areas.

Wetland Protection There is a wetland area at the foot of the steep slopes adjacent to the north property line. The wetland is offsite and will not be affected by the project. Stormwater runoff from the project site will be collected and conveyed outside of the wetland area and its respective buffer before discharging into the existing wetpond. The outlet from the wetpond will be outside of the wetland and its buffer, therefore the wetland will remain unaffected by the project. Minimum Requirement #8 applies only to projects whose stormwater discharges into a wetland, either directly or indirectly through a conveyance system, therefore no further requirements apply. 4.3 Detention Calculations The project is not required to meet Minimum Requirement #7: Flow Control as stormwater runoff will be discharged directly to a flow control exempt surface water. Stormwater will be detained in the existing wetpond located north of the project site for water quality purposes only. Refer to Section 4.5 for information regarding water quality for this project.

Per the 2014 SMMWW, enhanced treatment is required for multi-family residential and commercial projects. The project is a multi-family residential project and therefore must provide Enhanced Treatment. The flow chart below from the 2014 SMMWW assists in selecting a water quality facility for the site. Water Quality Facility Flow Chart Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-7 Following the flow chart, the project must select an enhanced treatment facility from the list provided. The project elects to implement a Stormwater Treatment Wetland. The existing wetpond located north of the project site will be regraded as part of this project to meet the requirements of a Stormwater Treatment Wetland per BMP T10.30 in the 2014 SMMWW and ensure proper function and storage capacity. Sizing information for the stormwater treatment wetland is provided below. Stormwater Treatment Wetland A Stormwater Treatment Wetland is proposed to meet the enhanced treatment water quality requirement. The project will collect and convey stormwater runoff to the existing wetpond that will be regraded as part of this project. The treatment wetland water quality facility will be sized using the procedure provided in Chapter V-10 of the 2014 SMMWW (BMP T10.30). 1. The volume of a basic wetpond is used as a template for sizing the stormwater wetland. The design volume is the total volume of runoff from the 6-month, 24-hour storm event. Alternatively, use the Water Quality Design Storm Volume estimated by an approved continuous runoff model. The water quality design storm volume estimated using MGS Flood is used and is shown below. Basic Wet Pond Volume (91% Exceedance): 44716. cu-ft 2. Calculate the surface area of the stormwater wetland. The surface area of the wetland shall be the same as the top area of a wetpond sized for the same site conditions. Calculate the surface area of the stormwater wetland by using the volume from Step 1 and dividing by the average water depth (use 3 feet). 44,716 ð‘ð‘ð‘ð‘ ð‘†ð‘†ð‘†ð‘† = = 14,906 ð‘ ð‘ ð‘ð‘ 3 ð‘ð‘ð‘“ð‘“ 3. Determine the surface area of the first cell of the stormwater wetland. Use the volume determined from Criterion 2 under â€œWetland Geometryâ€, and the actual depth of the first cell. Criterion 2 states that the presettling cell shall contain approximately 33% of the wetpool volume calculated in Step 1. ð‘‰ð‘‰ = 44,716âˆ—0.33 = 14,756 For a 5 foot deep presettling cell, the minimum required surface area is 2,951 square feet. The provided surface area of the presettling cell is 5,225 square feet. 4. Determine the surface area of the wetland cell. Subtract the surface area of the first cell (Step 3) from the total surface area (Step 2). ð‘Šð‘Šð‘Šð‘Šð‘“ð‘“ð‘Šð‘Šð‘Šð‘Šð‘Šð‘Šð‘Šð‘Š ð‘†ð‘†ð‘†ð‘† = 14,906âˆ’2951 = 11,955 ð‘ ð‘ ð‘ð‘ Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-8 The minimum required surface area for the wetland cell is 11,955 sf. The surface area provided for the wetland cell is 12,100 sf. 5. Determine water depth distribution in the second cell. Decide if the top of the dividing berm will be at the surface or submerged. Adjust the distribution of water depths in the second cell according to Criterion 8 under â€œWetland Geometryâ€. Note: This will result in a facility that holds less volume that the determined in Step 1 above. This is acceptable. The dividing berm will be placed at the water surface elevation, therefore the distribution of depths will be configured as follows from Table V-10.3.2: Depth Range (feet) Percent 0.1 to 1 25 1 to 2 55 2 to 2.5 20 6. Choose plants. See Table V-10.3.1 Emergent Wetland Plant Species Recommended for Wetponds for a list of plants recommended for wetpond water depth zones, or consult a wetland scientist. The wetland plants selected are shown on the landscape plans submitted under separate cover. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-9 SECTION 5. CONVEYANCE SYSTEM ANALYSIS AND DESIGN The tight-lined storm drainage system for the site was designed for the 25-year storm utilizing the Rational Method per the 2017 WSDOT Hydraulics Manual. Backwater Analyses were completed using the flows tabulated in the rational method calculated conveyance spreadsheets. The total site area was delineated into separate basins for each storm structure in order to evaluate the capacity of the system. A weighted runoff coefficient â€œCâ€ was calculated for the entire site based on surface types. This value was determined using the following equation: ð¼ð¼(ð¶ð¶ð¼ð¼)+ð‘ƒð‘ƒ(ð¶ð¶ð‘ƒð‘ƒ) ð¶ð¶ = ð¼ð¼ +ð‘ƒð‘ƒ Where: I = Impervious area in acres in the developed condition P = Pervious area in acres in the developed condition CI = Runoff coefficient for impervious area type, Rational Method CI = 0.9 for pavement and roofs CP = Runoff coefficient for pervious area type, Rational Method CP = 0.25 for lawns (Table 3.2.1.A) (6.53âˆ—0.9)+(7.13âˆ—0.25) ð¶ð¶ = 6.53+7.13 ð‘ªð‘ª = ðŸŽðŸŽ.ðŸ“ðŸ“ðŸ“ðŸ“ The conveyance and backwater calculations are provided in the following pages. Also refer to Figure 5-1 at the end of this section for basin areas of each drainage structure. The conveyance calculations will show that the conveyance system can safely convey stormwater runoff to the offsite wetpond without overtopping during the 25-year design storm. Core Design, Inc.

ESC ANALYSIS AND DESIGN A CSWPPP will be prepared and submitted under separate cover prior to final engineering approval. A TESC plan has been prepared and submitted with the civil plans. The site will utilize Volume II of the 2014 DOE SMMWW for the erosion and sedimentation control design to reduce the discharge of sediment-laden runoff from the site. Clearing limits will be established prior to any earthwork on the project site. Perimeter protection will be provided by silt fencing along the downstream perimeter of the disturbed areas to limit the downstream transport of sediment to streams, wetlands and neighboring properties. Dust control, if required, will be provided by a water truck. A Certified Erosion and Sediment Control Lead inspector will be present onsite during earthwork activities. The inspector shall determine frequency of watering of the project site and will authorize and direct any additional erosion and sediment control measures as needed during all construction activities. The plan will be comprised of temporary measures (stabilized construction entrance, silt fence, interceptor swales, etc.) as well as permanent measures (detention ponds, hydroseeding, etc.). In general, construction activities will be sequenced such that the permanent detention pond will be constructed and used for temporary erosion and sedimentation control. Runoff from the site will sheet flow across cleared areas into temporary interceptor swales and into temporary pipes that discharge into the permanent detention pond or into the permanent conveyance system, when installed. Although the permanent detention pond will be used as the TESC pond for the project, the minimum TESC pond area, dewatering orifice diameter, and emergency spillway length are calculated below and compared to the proposed detention ponds to verify adequate TESC functionality. The TESC pond area was calculated for the project site using the 10-year storm event with the potential of work during the wet season (October 1 to April 30). The 10-year time step developed condition peak flow rate used for TESC pond area sizing is Q10 = 3.97 cfs TESC Pond Surface Area Calculations TESC Pond minimum surface area SA, is determined by the following equation: SA = 2080 sf/cfs * (Total Q10-developed) Where: SA = minimum TESC pond surface area (sf) Q10-developed = 10-year developed peak flow (3.97 cfs) SAmin = 8,258 sf The design bottom surface area of the proposed wetpond that will but used for TESC = 10,230 sf.

The subject property consists of one parcel situated in the Southwest Â¼ of Section 1, Township 31 North, Range 5 East, W.M. (Snohomish County Tax Parcel Number 31050100302200). SVC investigated the subject property and north-adjacent publicly accessible property for the presence of potentially regulated wetlands and fish and wildlife habitat conservation areas in June and August of 2019. Using current methodology, the site investigations identified three potentially regulated wetlands (Wetlands A-C), one drainage, and one intentionally and artificially excavated, non- jurisdictional farm pond on the subject property. The Stillaguamish River, Eagle Creek and a wetland complex associated with Eagle Creek are located or mapped as being located within 225 feet of the project area. Wetlands A and B are considered Category III wetlands with low habitat scores of 4 points which are subject to standard 60-foot buffers with the use of minimization measures per Arlington Municipal Code (AMC) 20.93.830(b). Wetland C is considered a Category III wetland with a low habitat score of 5 points which requires a standard 105-foot buffer. The drainage identified onsite does not appear to meet the definition of a regulated stream. In addition, onsite Wetlands B and C which have potential hydraulic connectivity to the drainage would not likely support juvenile salmonid species or habitat to be considered a regulated fish and wildlife habitat conservation area (FWHCA) per AMC 20.93.400(3), due to stagnant water conditions, high water temperature, and low dissolved oxygen levels and pH levels. Per AMC 20.93.730(a), the Stillaguamish River is a Type S water which requires a standard 150-foot buffer. In addition, the FEMA 100-year floodplain associated with the Stillaguamish River was identified on the northern half of the subject property. AMC 20.64.119(b) establishes a 250-foot riparian habitat zone (RHZ) extending landward of a Type S water for floodplain development in which no new disturbances that adversely affect the existing habitat function are allowed. No other potentially-regulated wetlands or fish and wildlife habitat were identified within 225 feet of the project area. The Applicant proposes residential redevelopment of the subject property that will include clearing and grading for residential lots and associated infrastructure including a maintenance access road. The proposed project was carefully designed to avoid impacts to the identified critical areas to the greatest extent feasible, and all wetland and buffer impacts are avoided. However, temporary construction activities in the 100-year floodplain are unavoidable. The existing non-jurisdictional farm pond within the 100-year floodplain will be improved and utilized as a stormwater pond for water quality treatment and detention, and a new maintenance access road to the stormwater pond is required. No net loss of floodplain storage will occur from the stormwater pond and maintenance road. All proposed project impacts within the FEMA floodplain will be located in the existing, degraded farm pond, or within the actively cultivated agricultural field. All areas temporarily impacted from construction activities will be replanted and reseeded as necessary. As such, the proposed project actions will result in no net loss of critical area and floodplain functions, and the project actions May Affect, but are Not Likely to Adversely Affect (NLAA) any ESA-listed species. 1916.0001 â€“ Gilman Walk at Country Charm i Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 The summary table below identifies potential regulatory status of local, state, and federal agencies.

Subject Property Location 2.2 Project Description The Applicant proposes residential redevelopment of the subject property that will include clearing and grading for residential lots and associated infrastructure including a maintenance access road. The proposed project was carefully designed to avoid impacts to the identified critical areas to the greatest extent feasible, and by locating all of the residential lots out of the 100-year floodplain and critical areas, negative impacts are entirely avoided. However, temporary construction activities in the 100- year floodplain are unavoidable due to the required onsite stormwater infrastructure. The existing 1916.0001 â€“ Gilman Walk at Country Charm 2 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 non-jurisdictional farm pond within the 100-year floodplain will be improved and utilized as a stormwater pond for water quality treatment and detention, and a new maintenance access road to the stormwater pond is required. No net loss of floodplain storage will occur from the stormwater pond and maintenance road, and as such compensatory flood storage is not required. All proposed project impacts within the FEMA floodplain will be located in the existing, degraded farm pond, or within the actively cultivated agricultural field. All areas temporarily impacted from construction activities will be replanted and reseeded as necessary. As such, the proposed project actions will not result in negative impacts to critical areas and no net loss of floodplain functions; the project actions are NLAA ESA-listed species. ESA species information and effects determinations are presented in Chapter 7 of this report. 2.3 Action Area The â€œAction Areaâ€ encompasses the locations where project activities will occur (the Project Area) as well as all areas that may be directly or indirectly affected by the proposed project through physical, chemical, or biological mechanisms. The geographic limits of the Action Area were defined by considering the potential spatial extent of mechanisms that may lead to impacts on listed species. Mechanisms identified as having potential for impacting ESA-listed species or species habitat include noise from construction equipment and a potential increase in turbidity from sediment in-water suspension caused by construction activities; however, this project has no surface water connections, therefore water quality impacts are not anticipated. The Action Area for these potential impact mechanisms is depicted in Appendix D. 2.3.1 Terrestrial Noise In order to define the Action Area, this assessment discusses the project actions potentially generating noise levels above normal daily noise levels found in the vicinity of the project area. At certain levels, noise from project activities can adversely affect wildlife with various behavioral and/or health-related consequences (WSDOT, 2019). Terrestrial noise (transmitted through air) is measured in decibels (dBA) on an â€œAâ€-weighted (frequency weighted to approximate human hearing) logarithmic scale. Project construction will utilize several common types of construction equipment. Among those likely to be used, the three pieces having the loudest noise levels are a grader, a dozer, and a concrete pump truck. The use of construction equipment in this area will potentially lead to a higher noise level than traffic noise and ambient sound levels during portions of the project actions. The Washington State Department of Transportation (WSDOT) Biological Assessment Preparation Advanced Training Manual, Version 2019, lists average noise levels for typical construction equipment; average ambient sound levels per population density of the surrounding area; and noise levels for automobile traffic given certain speeds. According to WSDOT, the average decibel level at 50 feet from operation of a grader is 89 dBA, from a dozer is 82 dBA, and from a concrete pump truck is 81 dBA. Using decibel addition, 90 dBA was calculated to be the loudest projected noise level that will be heard at a 50 foot radius from where the construction actions will be performed, in the worst case scenario that all of these pieces of loud equipment are used at the same time. The subject property is located approximately 715 feet east of State Route 530. The average vehicles per hour along this section of State Route 530 is 1,400 (WSDOT, 2018). Following Table 7-3 from the WSDOT manual, the typical noise level for 1,000 vehicles per hour traveling at 40 miles per hour is 67.4 dBA. The typical noise level for 2,000 vehicles per hour traveling at 40 miles per hour is 70.4 dBA. The noise level from 1,400 vehicles per hour traveling at 40 miles per hour was estimated to be 68.9 dBA. Based on data from the 2010 U.S. Census and adjusted for the population growth rate, the 1916.0001 â€“ Gilman Walk at Country Charm 3 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 population density in the vicinity of the proposed project area is 2,981 people per square mile (Esri, 2019). The background noise level associated with this population density is 50 dBA. As the background noise level based on the nearby traffic noise level from State Route 530 at the subject property exceeds the background noise level based on the population density, the attenuation distance for the proposed project construction noise is based on noise level associated with the traffic level. Additional background noise near the subject property includes farm equipment noise and the noise of the South Fork of the Stillaguamish River. According to WSDOT, the average decibel level at 50 feet from operation of a tractor is 84 dBA, and nearby agricultural activities likely raises the background noise level beyond the level associated with the traffic. As such, the estimated Action Area for noise based on traffic is likely a conservative estimate. Construction noise levels will be elevated above normal background noise for a short time but will not reach levels that are likely to significantly impact terrestrial species. Sound impacts on ESA-listed species are discussed in Chapter 8. For terrestrial noise, standard attenuation is about 6-7.5 dBA per doubling of distance from the source of noise, depending on whether the site is classified as hard or soft (WSDOT, 2019). Using a background noise level of 68.9 dB (WSDOT, 2019), considering the residential and agricultural setting, and normal attenuation of 7.5 dB per doubling of distance over â€œhardâ€ surfaces, the construction noise will attenuate to background levels at approximately 568 feet (or 0.10 mile) (Table 1 and Figure 2). Therefore, the Action Area for noise has an approximate 568- foot radius around project activities. Table 1. Terrestrial Noise Attenuation Calculations.

This impervious areas may have an effect on local hydrologic and water quality function within the watershed; however, the proposed stormwater infrastructure is anticipated to adequately address the changes in land cover proposed by the project, so that no detrimental effects to downstream areas occur. In addition, the project will provide enhanced water quality treatment of stormwater. As no stormwater infrastructure exists onsite that meets current stormwater design standards, and as the site is in agricultural production, the proposed project is anticipated to result in a net gain in water quality function over existing baseline conditions. The majority of the proposed project work is located south of East Gilman Avenue and separated from the onsite wetland by the road. Proposed work adjacent to the onsite wetland buffers consists of stormwater infrastructure improvement. The proposed stormwater infrastructure will be located outside of Wetland A and the associated buffer, and no turbidity impacts are anticipated. As no further mechanisms for project impacts are anticipated, the overall Action Area is characterized by the 568-linear-foot terrestrial noise radius surrounding the proposed project area. 1916.0001 â€“ Gilman Walk at Country Charm 5 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 3. Methods SVC investigated, delineated, and assessed wetlands, waterbodies, and other potentially regulated fish and wildlife habitat conservation areas on and within 225 feet of the project area in June and August of 2019. All determinations were made using observable vegetation, hydrology, and soils in conjunction with background data collected from the U.S. Geological Survey (USGS) topographic map, Natural Resources Conservation Service (NRCS) soil survey, U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI), Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species (PHS) and SalmonScape mapping tools, Washington State Department of Natural Resources (DNR) water typing data, Snohomish County Geographic Information Systems (GIS) data, local precipitation data, and various orthophotographic resources. Appendix A contains further details for the methods and tools used to prepare this report. Wetland boundaries were determined using the routine approach described in the U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory, 1987) and modified according to the guidelines established in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE, 2010) and Field Indicators of Hydric Soils in the United States (NRCS, 2018). Qualified wetland scientists marked boundaries of onsite wetlands with orange surveyorâ€™s flagging labeled alpha-numerically and tied to 3- foot lath or vegetation along the wetland boundary. Pink surveyorâ€™s flagging was labeled alpha- numerically and tied to 3-foot lath or vegetation at formal sampling locations to mark the points where detailed data was collected (DP-1 to DP-9). Additional tests pits were excavated at regular intervals inside and outside of the wetland boundaries to further confirm the delineations. Wetlands were classified using both the hydrogeomorphic (Brinson, 1993) and Cowardin (Cowardin, 1979; Federal Geographic Data Committee, 2013) classification systems. Following classification and assessment, all wetlands were rated and categorized using the Washington State Wetlands Rating System for Western Washington â€“ Washington State Department of Ecology Publication No. 14-06-029, published October 2014 (Hruby, 2014) and guidelines established in AMC 20.93.800. The fish and wildlife habitat assessment was conducted during the same site visit by a qualified fish and wildlife biologists. The experienced biologists made visual observations using stationary and walking survey methods for both aquatic and upland habitats noting any special habitat features or signs of fish and wildlife activity. 1916.0001 â€“ Gilman Walk at Country Charm 6 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 4.

Sultan silt loam is considered a partially hydric soil. 4.3 Vegetation Upland vegetation on the northwest portion of the site consists of hairy catâ€™s ear (Hypochaeris radicata), white clover (Trifolium repens), and bentgrass (Agrostis sp.). Along the steep embankment directly north of East Gilman Avenue, vegetation is dominated by a narrow canopy of western red cedar (Thuja plicata) and big leaf maple (Acer macrophyllum) with an understory of non-native invasive Himalayan blackberry (Rubus armeniacus), and salmonberry (Rubus spectabilis). The southern portion of the site to the south of East Gilman Avenue is disturbed from recent structure demolition activities and consists primarily of weedy grasses and forbs. 4.4 Wetland and Stream Inventories The USFWS NWI map (Appendix B2) and Snohomish County wetland and stream inventory (Appendix B3) identify several potential wetlands in the agricultural fields on the northern portion of the site and slightly offsite. These maps also identify the presence of potential wetlands associated with the South Fork Stillaguamish River to the west and Eagle Creek to the East of the subject property, outside of the project area. The DNR stream typing map (Appendix B4) identifies the South Fork Stillaguamish River as a shoreline of the state (Type S) and Eagle Creek as a fish-bearing water (Type F). The FEMA floodplain map (Appendix B8) identifies the 100-year floodplain associated with the South Fork Stillaguamish River on the northwest portion of the site. No other wetlands or streams are identified on or within 225 feet of the subject property. 4.5 Priority Habitats and Species The WDFW PHS map (Appendix B6) and WDFW SalmonScape map (Appendix B7) identify the documented presence of coho, chinook, chum, pink, and sockeye salmon as well as bull, rainbow, cutthroat, and steelhead trout in the South Fork Stillaguamish River offsite to the west from the northwest portion of the site. These maps also identify the documented presence of coho salmon and presumed presence of cutthroat trout in Eagle Creek offsite to the east of the site. No other priority habitats or species were identified within 225 feet of the subject property. 4.6 Precipitation Precipitation data was obtained from the National Oceanic and Atmospheric Administration (NOAA) station at SeaTac International Airport in order to acquire percent of normal precipitation for the 1916.0001 â€“ Gilman Walk at Country Charm 9 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 general Puget South region during and preceding the site investigations. A summary of data collected is provided in Table 2. Table 2.

Precipitation levels provided in inches. Data obtained from NOAA (http://w2.weather.gov/climate/xmacis.php?wfo=sew) for SeaTac International Airport. 2. Year-to-date precipitation is for the 2018/2019 water year from October 1 to the onsite date. 3. Percent of normal is shown for the last 30 days and 2018/2019 water year. Precipitation levels during the June 2019 site investigation were below the statistical normal range for the prior 30 days (38 percent of normal) and within the normal range for the 2018/2019 water year (88 percent of normal). Precipitation levels during the August 2019 site investigation were slightly above statistical normal for the prior 30 days (140 percent of normal) and within the normal range for the water year (90 percent of normal). The minimal precipitation recorded in the prior 30 days leading up to the site visits is very insignificant (despite the Percent of Normal shown) as the months of June and August are typically dryer with minimal precipitation. These precipitation data suggest that hydrologic conditions during the time of the site investigation were likely normal. Such conditions were considered in making professional wetland boundary determinations. 1916.0001 â€“ Gilman Walk at Country Charm 10 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 5. Results The June and August 2019 site investigations identified three potentially regulated wetlands (Wetlands A-C), one drainage, and one intentionally and artificially excavated, non-jurisdictional farm pond on the subject property and the Stillaguamish River, Eagle Creek and a wetland complex associated with Eagle Creek within 225 feet of the project area. No other potentially-regulated wetlands, waterbodies, fish and wildlife habitat, or priority species were identified within 225 feet of the subject property during the site investigations. 5.1 Wetlands The site investigations identified three potentially regulated wetlands on the subject property (Wetlands A-C). The identified wetlands contained indicators of wetland hydrology, hydric soils (assumed for Wetland C), and a predominance of hydrophytic vegetation according to current wetland delineation methodology.

The farm pond is artificially and intentionally created by excavating an upland area, and is characterized by steep, tall berms along the edges that form a rectangular shape, distinctive of manmade conditions. An above-ground drainage pipe was observed south of the pond and appears to be contributing to the pond. It appears that the pond was intentionally breeched a few years ago. The feature does not meet the definition of a wetland under AMC 20.93.100 as this feature appears to be an artificially excavated pond, intentionally created from dry land for agricultural purposes (e.g. to provide a source of water for both irrigation and livestock). As described in AMC 20.93.100, â€œwetlands do not include those artificial wetlands intentionally created from non-wetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenitiesâ€. In addition, it appears the farm pond is an excavated depression intentionally created in dry land, for agricultural purposes, and therefore, per 33 CFR 328.3(b)(4)(ii) and (iv), this features is not considered Waters of the United States and is categorically exempt from jurisdiction by the USACE. Further, this feature is not expected to be regulated under the Revised Code of Washington (RCW) 90.48 as it does not meet the Washington Administrative Code (WAC) definition of a wetland, which states that â€œwetlands do not include those artificial wetlands intentionally created from non-wetland sites including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities.â€ Historical aerial photographs help to reveal the history of this farm pond feature. From 1933 to 1981 (Appendices B9 and B10) the site was in agricultural use with no indication of the presence of ground saturation or inundation that would suggest potential wetland presence. The farm pond is then clearly present in 1990 with continued surrounding agricultural use (Appendix B11) and continued to be regularly maintained as seen in the September 2006 Google Earth historical aerial photograph (Appendix B12) until being decommissioned in the last 10 years. As the farm pond is clearly an intentionally, artificially excavated feature from uplands, it should not be considered a regulated waterbody, and therefore no buffer is warranted. 5.3 Artificial Stormwater Drainages Several artificial drainages were observed along the hillslope to the north of East Gilman Avenue. These drainages are characterized by small diameter PVC pipes that appear to be contributing stormwater from the upslope areas. None of the drainages exhibited defined bed and bank or sorting and were surrounded by predominantly facultative-upland (FACU) species. In addition, the source of hydrology appears to be artificial stormwater runoff from East Gilman Avenue. Per AMC 20.93.100, streams do not include â€œirrigation ditches, canals, stormwater runoff devices or other entirely artificial watercourses unless they are used to convey any stream naturally occurring prior to construction.â€ Due to the lack of defined channels and the artificial nature of these drainages, they should not be considered regulated streams, and therefore no buffers are warranted. 5.4 Offsite Drainage A drainage feature was identified just offsite to the west of the subject property outside of the proposed project area. This drainage is recognized as the permanently flowing outlet from the western end of Wetland C as it becomes narrower and more channelized. The drainage flows west for 1916.0001 â€“ Gilman Walk at Country Charm 16 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 approximately 440 feet before likely discharging into the South Fork Stillaguamish River. This feature does not meet stream definition criteria per AMC 20.93.100, which defines streams as â€œthose areas where surface waters flow sufficiently to produce a defined channel or bed. A defined channel or bed is indicated by hydraulically sorted sediments or the removal of vegetative litter or loosely rooted vegetation by the action of moving water.â€ While this drainage feature exhibits a partially defined channel in areas, it does not exhibit a defined bed, and as such should not be considered a regulated stream. In addition, onsite Wetlands B and C which have potential hydraulic connectivity to the drainage would not likely support juvenile salmonid species or habitat to be considered a regulated fish and wildlife habitat conservation area (FWHCA) per AMC 20.93.400(3), due to stagnant water conditions, high water temperature, and low dissolved oxygen levels. 5.5 Offsite South Fork Stillaguamish River and Eagle Creek The South Fork Stillaguamish River was identified flowing west directly offsite to the northwest of the subject property, outside of the proposed project area. The DNR and Snohomish County identify the South Fork Stillaguamish River as a shoreline of the state (Type S), and WDFW identifies the documented presences of coho, chinook, chum, pink, and sockeye salmon as well as bull, rainbow, cutthroat, and steelhead trout in this waterbody. The FEMA identifies the 100-year floodplain associated with the South Fork Stillaguamish River on the northwest portion of the site. Given the distance from the project area, the proposed development is not anticipated to impact the river or associated buffer. However, the project may require work within the 100-year floodplain but will result in no net loss of floodplain area and function. Eagle Creek is documented offsite south and east of the subject property. Salmoncape identify the documented presence of coho salmon and presumed presence of cutthroat trout in Eagle Creek offsite to the east of the site. In addition, it appears there is an associated wetland complex offsite and adjacent to Eagle Creek. No development is proposed within approximately 200-feet of Eagle Creek or the offsite wetland complex. 1916.0001 â€“ Gilman Walk at Country Charm 17 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 6. Regulatory Considerations The northern portion of the subject property is adjacent to the South Fork of the Stillaguamish River, and the subject property is partially located within the 100-year floodplain of the river. The site investigations identified and delineated three potentially regulated onsite wetlands (Wetlands A-C). The site investigations also identified an offsite drainage that potentially connects Wetland C to the South Fork of the Stillaguamish River, as well as an artificially created, offsite farm pond adjacent to Wetland A. The project was carefully designed to avoid and minimize impacts to critical areas to the greatest extent feasible and avoids all negative impacts to the identified onsite and offsite critical areas and buffers. However, the proposed stormwater pond and maintenance access road are required to be located within the FEMA 100-year floodplain. No net loss of flood elevations or floodplain storage will occur from the stormwater pond and maintenance road, and no negative impacts to ESA-listed species are anticipated. This chapter discusses the regulatory implications and considerations of the proposed project. 6.1 Local Shoreline Requirements The northern portion of the subject property is adjacent to the regulated shoreline of the South Fork of the Stillaguamish River. The City of Arlington SMP 3.1 describes the shoreline jurisdiction for the City as approximately identified on the map in Appendix A of the SMP, and states that the actual lateral extent of the shoreline jurisdiction shall be determined on a case-by-case basis based on the location of OHW, floodway, and presence of associated wetlands. The minimum shoreline jurisdiction identified on the SMP Minimum Shoreline Jurisdiction map appears to include the floodway of the South Fork of the Stillaguamish River and does extend onto the northern and western portions of the subject property. The City of Arlington SMP 3.1 states that in circumstances where the shoreline jurisdiction does not include the entire parcel only the use, activity, or development on the portion of the part of the parcel within the shoreline jurisdiction is subject to the SMP regulations. The proposed project area is located outside of the minimum shoreline jurisdiction as shown identified the City of Arlingtonâ€™s map. As such the proposed project is located outside of the Cityâ€™s shoreline jurisdiction. 6.2 Local Critical Area Requirements 6.2.1 Wetland Buffer Standards Wetlands A and B are considered Category III wetlands with low habitat scores of 4 points which are subject to standard 60-foot buffers with the use of minimization measures per Arlington Municipal Code (AMC) 20.93.830(b) and Table 20.93-4. Wetland C is considered a Category III wetland with a low habitat score of 5 points which requires a standard 105-foot buffer. Per AMC 20.93.830.b.1 the use of standard buffer widths requires the use of the minimization measures identified in AMC Table 20.93-5 (Table 7 below). Additionally, a 15-foot building setback is required from the edge of any critical area buffer per AMC 20.93.340. 1916.0001 â€“ Gilman Walk at Country Charm 18 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Table 7.

Per AMC 20.93.730(a) a Type S waterbody is subject to a 150-foot buffer. No work is proposed within the buffer for the South Fork of the Stillaguamish River. Per AMC 20.93.400(3) fish and wildlife habitat conservation areas include segments of natural waters and periodically inundated areas of their associated wetlands that are used by salmonids for off- channel habitat. This off-channel habitat must be connected to a salmonid-bearing stream and accessible during some period of the year and be accessible to juvenile salmonids through a drainage with less than 5 percent gradient. Onsite Wetlands B and C have potential hydraulic connectivity to the drainage; however, these wetlands do not likely support juvenile salmonid species or habitat to be considered a regulated fish and wildlife habitat conservation area (FWHCA) per AMC 20.93.400(3), due to stagnant water conditions, high water temperature, and low dissolved oxygen levels. As such, no FWHCA buffers are likely required. In addition, the project does not propose negative impacts to Wetland B or Wetland C, and development is proposed within areas already developed or improved. Even if Wetlands B and C were classified as FWHCA, the potential buffer would be interrupted by Gilman Avenue and would not project onto the project area. 6.2.3 Floodplain Habitat Requirements Due to the size, shape, and location of the site, the location of the proposed stormwater pond and associated maintenance access road cannot be proposed outside of the FEMA floodplain. Floodways and floodplains are regulated under AMC 20.64. According to AMC 20.64.110(b), a riparian habitat zone (RHZ) is an overlay zone that encompasses the land on either side of streams and off channel areas within special flood hazard areas. The RHZ is considered a no new disturbance zone, other than for activities that will not adversely affect the existing habitat function. Unless shown otherwise, the RHZ along a channel migration zone is 50 feet. Per AMC Table 20.63.120, Type S waterbodies are subject to a 250-foot buffer/RHZ. The proposed project is located outside of the 250-foot buffer for the South Fork of the Stillaguamish River, and no impacts are proposed to this buffer/RHZ. AMC 20.64 (Floodplain Development Regulations) includes floodplain development restrictions related to listed salmonid habitat. These development restrictions are described for development within and outside protected areas. AMC 20.64.050 describes the protected area as â€œthe greater of the floodway, the channel migration zone, and the riparian habitat zone within the FEMA mapped special flood hazard area.â€ Per AMC 20.64.140(b)(1)(A), all structures must be set back 15 feet from the edge of the â€œprotected area.â€ The City of Arlington Streams, Riparian Habitat Zone, Floodplain, and Floodway map identifies the FEMA floodway and RHZ as being located within the same area on the western portion of the subject property. The FEMA floodway and RHZ extent exceeds the extent of the channel migration zone, and the area covered by the FEMA floodway and RHZ is therefore considered as a protected area. No work is proposed within the protected area or within the building setback from the protected area; however, the proposed stormwater pond and associated maintenance access road will be located within the 100-year floodplain and likely subject to the requirements of AMC 20.64.150(2) for development outside the protected area. AMC 20.64.150(2) requires that any floodplain development outside the protected area mitigate for adverse effects, both direct and indirect on functions such that equivalent or better salmon habitat protection is provided for: 1916.0001 â€“ Gilman Walk at Country Charm 20 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 A. Stormwater. Reduce flood volumes and stormwater runoff from new development by ensuring that increased flood volumes of stormwater reach the river at the same frequency, timing and duration as historic runoff. Low impact development is required to be incorporated as described in Section 20.64.140(b)(2). The development proposed within the floodplain is limited to the stormwater pond and associated maintenance access road and no new sources of stormwater runoff are proposed within the floodplain. The purpose of the stormwater pond is to treat and detain runoff from the proposed residential development located outside of the floodplain. The proposed stormwater pond is designed to ensure that runoff from the development does not alter the flow of the river. Enhanced stormwater treatment will be provided. B. Riparian vegetation: maintain or replace riparian function by providing equivalent area, diversity, and function of riparian vegetation as currently exists on the site. Riparian retention requirements are outlined in subsection (1)(H). The riparian retention standard identified by AMC 20.64.150(1)(H) states that removal of native vegetation must leave 65 percent of the surface area of the portion of the property in the floodplain in an undeveloped state. The majority of the floodplain within the subject property has been historically modified and farmed, including areas adjacent to the proposed stormwater infrastructure. The agricultural field located within the floodplain is actively cultivated and in agricultural production. Some native vegetation is present immediately west of the proposed stormwater pond area. Any native vegetation disturbed during construction of the stormwater pond and maintenance access road will be revegetated. The proposed project will leave the entirety of the onsite floodplain area in an undeveloped state. C. Hyporheic Zones. No activity is allowed that interferes with the natural exchange of flow between surface water, groundwater, and hyporheic zone, however, natural hyporheic exchange may be enhanced or restored. The proposed stormwater pond and maintenance access road is not anticipated to interfere with the exchange of flow between surface water, groundwater, and hyporheic zone in the floodplain. D. Wetlands. Wetland function must be maintained or replaced by providing equivalent function. No wetland impacts are proposed. E. Large Woody Debris. Any large woody debris (LWD) removed from the floodplain must be replaced in kind, replicating or improving the quantity, size, and species of the existing LWD. The project area does not provide any special habitat features such as LWD; therefore, no LWD will be removed. The proposed project is not expected to adversely affect any ESA-listed species, as outlined in Chapter 7 of this report. The proposed stormwater pond will be located within the existing farm pond, and the proposed stormwater maintenance access road will be located in the existing degraded, actively 1916.0001 â€“ Gilman Walk at Country Charm 21 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 cultivated agricultural field (Appendix C). The accumulated materials at the bottom of the existing farm pond were determined to not meet for fecal coliform and should not require special handling or disposal, according to the environmental consultant. The proposed stormwater pond will be developed within the constraints of the existing farm pond and will not result in a loss of floodplain storage and will not impact floodplain habitat. The maintenance access road will require gravel surfacing; prior to gravel placement, an equivalent amount of soil will be scraped from the surface. As such, the proposed stormwater infrastructure and maintenance access road are designed to result in no net loss of flood storage capacity and no change in flood elevations. Further, the project will have no substantial impact on water quantity or quality. The proposed project will incorporate appropriate stormwater best management practices (BMPs) and will adhere to site-specific erosion and stormwater control plans, as applicable. 6.3 State and Federal Considerations 6.3.1 The Federal Clean Water Rule The results of the site investigations identified three onsite wetlands, artificially created drainages onsite and offsite, and one artificially created offsite farm pond. In addition the South Fork of the Stillaguamish River is located along the northwestern boundary of the subject property. The Federal Register published a final revised Clean Water Rule: â€œDefinition of Waters of the United Statesâ€ on 29 June 2015 (FR Vol 30, No. 124; pages 37054 â€“ 37127). The effective date of this rule was to be 28 August 2015. This rule provided a definition of Waters of the United States (WOTUS), different from that in the 2 December 2008 joint memorandum from EPA and USACE following the U.S. Supreme Courtâ€™s Decision in Rapanos v. United States & Carabell v. United States (USACE, 2008). Implementation of the 2015 Clean Water Rule was stayed by the U.S. 6th Circuit Court of Appeals on 9 October, 2015-- a little over one month after that ruleâ€™s effective dateâ€”until recently. On 28 Feb, 2017 President Trump issued Executive Order 13778 ordering EPA and USACE to review and or rescind the clean water rule. This was followed by the Suspension Rule (6 February 2018), which delayed implementation of the clean water rule to 6 February 2020 and provided time for a two part rulemaking process to revise the definition of WOTUS. But in August 2018, Judge David C. Norton of the U.S. District Court for South Carolina issued an injunction claiming that the Suspension Rule was in violation of the Administrative Procedures Ac. This injunction effectively reinstated the Clean Water Rule in 26 states, including Washington. Therefore, at the time of writing this report, the 2015 Clean Water Rule is currently in use within the State of Washington to describe waters that are to be regulated under section 404 of the CWA. The 2015 Clean Water Rule describes the following waters where jurisdiction would be asserted: 1) traditional navigable waters: all waters which are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, included all waters which are subject to the ebb and flow of the tide; 2) interstate waters (including interstate wetlands); and 3) the territorial seas. The following extensions of those waters are also considered to be waters of the United States: all impoundments of these waters, all tributaries of these waters (as defined in the Clean Water rule), all waters â€œadjacentâ€ to these waters (as defined in the Clean Water rule), to their impoundments or to their tributaries, and all waters located within the 100-year floodplain of a traditional navigable water, 1916.0001 â€“ Gilman Walk at Country Charm 22 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 interstate water, or territorial sea, or within 4,000 feet of the high tide line or ordinary high water of any water otherwise determined to be a water of the U.S. that has a significant nexus to a traditional navigable water, interstate water, or territorial sea. The 2015 Clean Water Rule also describes fifteen types of waters or areas where jurisdiction will NOT be asserted, even if they otherwise meet the precedent descriptions of WOTUS: (1) waste treatment systems, including treatment ponds or lagoons designed to meet the requirements of the CWA, (2) prior converted cropland, (3) ephemeral ditches that are not a relocated tributary or excavated tributary, (4) ditches with intermittent flow that are not a relocated tributary, excavated in a tributary, and that do not drain wetlands, (5) ditches that do not flow, directly or indirectly, into a traditional navigable water, interstate water, or territorial sea, (6) artificially irrigated areas that would revert to dry land should irrigation cease, (7) artificially constructed lakes and ponds, created in dry land, such as farm and stock watering ponds, irrigation ponds, settling basins, fields flooded for rice growing, log cleaning ponds, or cooling ponds, (8) artificial reflecting pools or swimming pools created in dry land, (9) small ornamental waters created in dry land, (10) water-filled depressions created in dry land incidental to mining or construction activity, including pits excavated for obtaining fill, sand, or gravel that fill with water, (11) erosional features, including gullies, rills, and other ephemeral features that do not meet the definition of tributary, non-wetland swales, and lawfully constructed grassed waterways, (12) puddles, (13) groundwater, including groundwater drained through subsurface drainage systems, (14) stormwater control features constructed to convey, treat, or store stormwater that are created in dry land, and (15) wastewater recycling structures constructed in dry land; detention and retention basins built for wastewater recycling; groundwater recharge basins; percolation ponds built for wastewater recycling; and water distributary structures built for wastewater recycling. The South Fork of the Stillaguamish River eventually drains into Puget Sound, a traditionally navigable water. As a tributary to a traditionally navigable water, the South Fork of the Stillaguamish River is regulated as a WOTUS under Category 1 above. Wetlands B and C appear to be within the 100-year floodplain for the South Fork of the Stillaguamish River and within 1,500 feet of the river. As wetlands that are â€œadjacentâ€ to a WOTUS as defined by the Clean Water Rule, these wetlands are likely regulated as WOTUS. Wetland A appears to be located outside of the floodplain; however, this wetland is located within 4,000 feet of the South Fork of the Stillaguamish River and could be potentially regulated as a WOTUS if the wetland was determined to have a significant nexus to the river. No direct impacts are proposed to these waterbodies potentially regulated as WOTUS. The offsite farm pond was determined to be an artificially constructed pond created from dry land for agricultural purposes. Review of historical aerial imagery indicates that the farm pond appeared to be constructed between 1981 and 1990. Prior to 1981 the area where the farm pond is currently located appeared to consist of an agricultural field. Following 1990, the farm pond appears as a rectangular and inundated feature. The farm pond likely meets the WOTUS exemption number 7 above for artificially constructed lakes and ponds, created in dry land, such as farm and stock watering ponds and settling basins. The artificial drainages observed onsite appear to be erosional features. These features likely meet the WOTUS exemption number 11 above for erosional features that do not meet the definition of tributary. 6.3.2 State Requirements The WSDOE also regulates wetlands and rivers through the Revised Code of Washington (RCW) 90.48. The identified wetlands and the South Fork of the Stillaguamish River are subject to the stateâ€™s 1916.0001 â€“ Gilman Walk at Country Charm 23 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 regulations. The farm pond is not expected to be regulated under RCW 90.48 as it does not meet the WAC definition of a wetland, which states that â€œwetlands do not include those artificial wetlands intentionally created from non-wetland sites including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities.â€ The farm pond was determined to be an intentionally, artificially constructed pond created from dry land for agricultural purposes. The identified drainages are not expected to be regulated under the RCW 90.48 as the drainages do not meet of the definition of a typed waterbody under WAC 22-16-030. No direct impacts are proposed to these waterbodies potentially regulated by WSDOE, and no coordination with WSDOE is anticipated. 1916.0001 â€“ Gilman Walk at Country Charm 24 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 7. ESA Species Information and Effects Determinations Under AMC 20.64.020(c) activities within the 100-year floodplain require a habitat assessment report prior to issuance of a floodplain development permit in order to ensure compliance with the ESA. The FEMA floodplain encumbers the area required for stormwater infrastructure (Appendix B8). This chapter assesses potential impacts to ESA-listed species and associated critical habitat, and provides impact determinations in compliance with ESA and the City of Arlingtonâ€™s floodplain development regulations. The project is anticipated to have no adverse effect on any ESA-listed species. 7.1 Species Information SVC staff reviewed data obtained from the National Oceanic and Atmospheric Administrationâ€™s National Marine Fisheries Service (NMFS), WDFW, and USFWS in order to determine species listed under the ESA that may be found in Snohomish County and in or near the Action Area. Table 8 contains a list of these species. Several of these species will not be found on or within the proposed project area or Action Area because the project location and surrounding environmental conditions do not support the presence of these species, acceptable habitat, or other associated resources; these species are briefly discussed in Section 7.1.1. Species and associated critical habitat potentially present and/or potentially affected by the proposed project are discussed in Section 7.1.2. The species with the potential to be impacted by the proposed project include marbled murrelet, steelhead trout, chinook salmon, bull trout, and Oregon spotted frog. Section 7.6 discusses the effect determinations for each of these species and the rationale behind those determinations. Table 8. ESA-Listed Species Potentially Found in Snohomish County. Federal Listing Potential for Species Name Common Name Status Impacts Brachyramphus marmoratus Marbled Murrelet Threatened Possible Canis lupus Gray Wolf Endangered None Coccyzus americanus Yellow-Billed Cuckoo Threatened None Eremophila alpestris strigata Streaked Horned Lark Threatened None Lynx canadensis Canada Lynx Threatened None Oncorhynchus mykiss Steelhead Trout Threatened Possible Oncorhyncus tshawytscha Chinook Salmon Threatened Possible Orcinus orca Southern Resident Killer Whale Threatened None Rana pretiosa Oregon Spotted Frog Threatened Possible Salvelinus confluentus Bull Trout Threatened Possible Strix occidentalis caurina Northern Spotted Owl Threatened None Ursus arctos horribilis Grizzly Bear Threatened None 7.1.1 Species Not Likely Present Several ESA-listed species potentially found in Snohomish County will not be found on or near the vicinity of the project area and will not be addressed further in this document. The proposed project is located within an urban residential and agricultural setting. The only terrestrial habitat is comprised 1916.0001 â€“ Gilman Walk at Country Charm 25 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 of an agricultural field, and even though the species in Table 8 may occur in Snohomish County, it is highly unlikely that these animals will be found in the vicinity of the project area. The ESA-listed species clearly not affected due to project location and surrounding environment conditions include the following: â€¢ Southern Resident Killer Whale (Orcinus orca) are marine mammals that feed primarily on chinook salmon. Due to the proposed projectâ€™s inland location, the only potential impact to southern resident killer whale is the possibility of an indirect impact to the whale following impacts to chinook salmon. The proposed project does not include direct impacts to the Stillaguamish River or off-channel habitat for chinook. Due to the lack of project impacts to potential chinook habitat, the proposed project will not impact the food supply for southern resident killer whale. As such the proposed project will have No Effect on Southern Resident Killer Whales. â€¢ Gray wolf (Canis lupus) generally inhabits temperate forests, mountains, tundra, taiga, and grassland environments. While they are somewhat habitat generalists, gray wolves do require ungulate prey or other wild animals for scavenging. In addition, they require a large amount of space (minimum of 10,000 to 13,000 square kilometers) with low road density to support a viable population (USFWS, 1990). Because the project area and vicinity are highly urbanized, no habitat for the gray wolf exists in project area; therefore, the project will have No Effect on Gray Wolf. â€¢ Yellow-billed cuckoo (Coccyzus americanus) are migratory birds and historically ranged from British Columbia to northern Mexico. Approximately 17 sightings in Washington have been reported between 1956 and 2012, the majority of which (13) were east of the Cascades. The yellow-billed cuckoo generally prefers riparian habitat of 50 acres or more (Daw, 2014). Due to a lack of suitable habitat within the vicinity of the project area, the project will have No Effect on Yellow-Billed Cuckoo. â€¢ Streaked horned lark (Eremophila alpestris strigata) is found primarily in prairie habitat or unvegetated to sparsely-vegetated open habitats (Pearson & Anderson, 2015). The current range of the streaked horned lark includes the Puget lowlands, in which the project area is located; however, the largest known populations of streaked horned larks breed in the southern Willamette Valley in Oregon. The streaked horned lark nests on the ground in sparsely vegetated sites dominated by grasses and forbs, in a broad range of habitats including sparsely-vegetated edges of grass fields. Wintering streaked horned larks use habitats similar to breeding habitats. However, studies conducted by the USFWS indicate that sites used by larks are generally found in open (i.e., flat, treeless) landscapes 300 acres or more in size such as airports (USFWS, 2013). Due to the lack of sizeable habitat and no documented presence or observations in the project area or vicinity, there will be No Effect on Streaked Horned Lark. â€¢ The distribution of Canada lynx (Lynx canadensis) in North America follows the distribution of boreal forest ecosystems and ranges from the south up into the subalpine forest of the western U.S. as well as into the boreal/hardwood forests of the eastern U.S. Their populations persist in areas with deep snow and large population of snowshoe hares, which is the main prey of the lynx (USFWS, 2016). No habitat for this species is found in the project area; therefore, the project will have No Effect on Canada Lynx. 1916.0001 â€“ Gilman Walk at Country Charm 26 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 â€¢ Northern spotted owl (Strix occidentalis) prefer habitat found in mature coniferous forests. Habitat for northern spotted owl was not identified within the subject site or vicinity. In Washington, the northern spotted owl is more likely to be encountered on the Olympic Peninsula or on both slopes of the Cascade Range. Rarely, the northern spotted owl occurs in remnant patches of mature or structurally complex forest in the Puget Trough and southwestern Washington (WDFW, 2012). No habitat for this species is found in the project area; therefore, the project will have No Effect on the Northern Spotted Owl. â€¢ Grizzly bears (Ursus arctos horribilis) require large territories, which range in size from 50 to 500 square miles depending on the sex of the animal. Grizzly bears prefer variable habitat near mountains with grasslands, meadows and forests to provide a range of foraging options. Grizzly bear populations in the North Cascade Mountains are thought to contain only 20 or so individuals (USFWS, 2007). Due to a lack of suitable habitat within the vicinity of the project area, the project will have No Effect on Grizzly Bear. 7.1.2 Species Potentially Present The proposed project is located in an urban residential and agricultural setting. The subject property consists of a developed area that is currently residential, demolished agricultural structures, a steep forested hillslope, emergent and aquatic bed wetlands, and a large actively cultivated agricultural field. The emergent and aquatic bed wetlands may potentially provide habitat for Oregon spotted frogs. In addition, the South Fork Stillaguamish River is located immediately offsite approximately 1,000 feet to the north/northwest, and has a documented presence of coho salmon, Dolly Varden/bull trout, fall chinook, fall chum, pink salmon, rainbow trout, coastal cutthroat trout, sockeye salmon, summer steelhead, and winter steelhead. Coho, pink, sockeye, chum, rainbow trout, and cutthroat trout are not listed species in this area and are not considered in detail in this document. Life histories are discussed below for ESA-listed species considered for impacts from this project. Species determinations are presented in Section 7.6.3. Puget Sound Steelhead Trout Oncorhynchus mykiss â€“ Threatened, listed May 11, 2007 National Oceanic and Atmospheric Administration (NOAA) Fisheries has identified fifteen (15) Distinct Population Segments (DPS) of steelhead trout in Washington, Oregon, and California. Steelhead trout populations can be divided into two (2) basic reproductive ecotypes, based on the state of sexual maturity at the time of river entry (summer or winter) and duration of spawning migration. Steelhead trout are iteroparous, meaning they can spawn more than once. Steelhead trout can spend up to seven (7) years in freshwater prior to smoltification (USACE, 2007). Crescent Creek and North Creek streams have documented winter steelhead trout presence (SalmonScape). Populations are considered â€œDepressedâ€ by WDFW SASI data (WDFW, 2002). Due to depressed populations the presence of steelhead trout in the Action Area during proposed project activities is likely minimal. WDFW identifies documented steelhead trout presence in the Stillaguamish River. Puget Sound Chinook Salmon ESU Oncorhynchus tshawytscha â€“ Threatened, listed (reaffirmed) June 28, 2005. Chinook salmon are a semelparous species that returns to natal streams to spawn during the summer and fall months, with abundance peaking in October. Adult chinook tend to move quickly through the Puget Sound when returning to natal streams to spawn. Chinook bury their eggs in gravel substrate, and the alevins emerge 3 months later between December to April. There are two main kinds of life history strategies for this species: stream type and the ocean type chinook. The stream 1916.0001 â€“ Gilman Walk at Country Charm 27 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 type migrates upstream earlier to spawn, from late spring to summer. After emergence they delay estuary migration to the following spring, overwintering in the river (Healy, 1998). Once they reach the Puget Sound, they spend little time there before moving out into deeper marine waters. There are two varieties of ocean type chinook: the delta fry remain in their natal delta for weeks to a few months before entering the estuary to rear, while parr migrants remain in freshwater to rear for up to 6 months before entering the natal estuary between May and July (Groot, 1991). Time spent in the Puget Sound is dependent on several factors including size, fry typically remain in estuarine nurseries until they reach about 70mm in fork length before moving seaward which usually occurs in under 2 months. Juvenile chinook abundance in the Puget Sound peaks around June and July, but they can still be found through October (Fresh, 2006). Once in marine waters, chinook salmon disperse widely, moving both northward and southward and will spend 2 to 4 years in the ocean. First ocean year stream type salmon prefer outer coasts while ocean type chinook utilize more sheltered waters (Groot, 1991). Fall Chinook populations in the Central and South Puget Sound regions are primarily sustained through hatchery production; indigenous populations have diminished from habitat degradation, over-fishing, and the use of hatchery fish in the ecosystem. Chinook are highly valued by the commercial fishery. Chinook range from Kotzebue Sound, Alaska down to Santa Barbara, California (PSMFC, 2012). Many of the rivers located within their range are used for Chinook spawning and rearing. In freshwater, spawning chinook require deep, coarse gravel with adequate irrigation to build their redds. Water temperatures must not exceed 14 degrees Celsius and as chinook are larger salmon, they are able to spawn in faster flowing rivers compared to other species. Chinook will spawn in a variety of habitats from small, shallow tributaries to the main stem of a large river. Most redds are built at the head of a riffle or in pools below log jams where the rate of sub gravel flow was increased (Groot, 1991). Adults have been documented to eat other salmon eggs during their upstream migration; the proportion of chinook showing this trait varies across rivers (Garner, 2009). Juvenile chinook feed first on plankton and then as they grow larger eat dipteran larvae, beetle larvae, stonefly nymphs and leaf hoppers. Bank cover is important for juveniles as it provides shade and protection from predators as well as increased prey. In estuaries chinook are opportunistic feeders and their diet varies from place to place within the estuary, in general they prefer larval and adult insects as well as amphipods (Hammerson, 2010). Eelgrass habitat is especially important to juvenile chinook and it has been documented that a majority of their diet consists of prey associated with eelgrass habitats (Kennedy, 2018). During high tide, juvenile chinook can be found in surface waters at the edges of the shoreline and move into tidal channels and creeks when the tide lowers. Smaller chinook are not able to perform osmoregulation at the same capacity as larger salmon and prefer lower salinity waters. Pocket estuaries are essential for juvenile chinook and they are found in greater abundance in these areas than offshore and nearshore sites. A majority of the chinook found in pocket estuaries are a rearing population as these habitats provide refuge from predators (Beamer, 2003). WDFW identifies documented chinook presence in the Stillaguamish River. Bull Trout Salvelinus confluentus â€“ Threatened, listed November 1, 1999 Bull trout are an iteroparous species that mature around ages 5 to 7 years and have a lifespan of 12 years or more. There are four life history strategies for Bull Trout: 1) non-migratory populations that spend their entire lives in small streams and headwater tributaries, 2) riverine populations that spawn in tributaries and mature in large rivers, 3) lacustrine populations that spawn in tributaries and mature 1916.0001 â€“ Gilman Walk at Country Charm 28 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 in lakes, and 4) anadromous populations that spawn in natal tributaries and migrate downstream to mature in nearshore estuarine and marine waters (USFWS, 2010). The anadromous populations are only found in western Washington. These populations tend to travel only modest distances throughout the Puget Sound, although some individuals have been known to travel greater distances and maintain prolonged residence in marine waters. They tend to overwinter in nearshore marine waters or lower portions of streams (Brenkman, 2005). Bull trout spawn in the fall, and the eggs incubate for approximately 220 days with emergence typically in the spring (Shellberg, 2002). Juveniles rear for a short time in their natal stream before migrating and maturing in nearshore marine areas in the late spring. Once sexual maturity is reached, they return to upper reaches of mountain freshwater streams to spawn, continuing this migration pattern to and from marine waters for up to 10 years. Nearshore use occurs predominantly in March through July (Goetz, 2003). Bull trout occur in less than half their historic range, with scattered populations throughout Oregon, Washington, Nevada, Idaho, and Montana. Four bull trout populations have been confirmed to enter the Puget Sound, these populations include the Lower Skagit, Skykomish, South Fork Skokomish and White River (Puyallup) bull trout. Temperature is a major factor in determining bull trout habitat. Bull trout cannot tolerate temperatures over 15 degrees Celsius and require temperatures below 9 degrees Celsius to initiate spawning. Stream and riverine bull trout habitats are found in channels with cold, stable flow; low levels of fine substrate sediment; clean gravel beds for spawning; and complex habitat features that still allow corridors for mitigation. Complex stream and riverine habitat features include abundant vegetation, debris jams, boulders, root wads, deep pools and undercut banks (Shellberg, 2002). In Washington bull trout can be found in major tributaries from the Cascades that flow into the Puget Sound as well as the major tributaries from the Olympic Mountains that flow into Hood Canal, Strait of Juan de Fuca and the Pacific Ocean (USFWS, 1999). After emergence, bull trout fry are most abundant in side-channels and pools with submerged cover (McPhail and Baxter, 1996). Juveniles eat small aquatic invertebrates, while adults are primarily fish predators. They are opportunistic feeders and will eat mountain whitefish, sculpins, darters, other trout, salmon fry, shrimps, snails, leeches and fish eggs (Hammerson, 2011). Lacustrine populations prefer oligotrophic and high-altitude lakes. They forge in the littoral zone in fall and spring and move to deep water in the summer, likely due to temperature constraints (Goetz, 1989). Within marine waters, bull trout prefer protected estuaries that contain coastal deposits, low banks, and sediment bluffs. Shallow water areas that contain eelgrass and green algae are important to bull trout and provide food for maturing juveniles (Hayes, 2010). In western Washington, small saltwater fish such as surf smelt, herring and sandlance are important food sources in marine habitats for adult bull trout (USFWS, 1999). WDFW identifies documented bull trout presence in the Stillaguamish River. Marbled Murrelet Brachyrhampus marmoratus - Threatened, listed 1992 - Critical Habitat designated November 13, 2014 (79FR68041) Marbled murrelet are members of the Alcidae family of seabirds such as puffins, murres, and auklets. In the state of Washington, they are year-round residents on coastal waters. They primarily feed in waters within 500 feet of the shore out to 1.2 miles from shore at depths of less than one hundred feet. Preferred prey includes small fish and crustaceans; nestlings may be fed larger fish. Nests and roosts are found in mature and old growth forests of western Washington. Marbled murrelets will fly along river corridors to reach their nests. Nesting typically occurs from April to September (WDFW, 1991). Nest trees are typically greater than thirty-two inches diameter at breast height, with nesting preference on large flat conifer branches, often covered with moss (WDFW, 1991) and found in old 1916.0001 â€“ Gilman Walk at Country Charm 29 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 growth forests. They travel along river corridors to reach their nests. Marbled murrelets have been found in the largest numbers in marine waters near the coastal waters surrounding the Olympic Peninsula (Pearson et.al., 2010). There have also been two confirmed occupied nesting sites in old growth forests within the Cedar River Watershed of King County. Marbled murrelet are more sparsely distributed elsewhere in this region. Prey species (sand lance (Ammodytes hexapterus), surf smelt (Hypomesus pretiosus), and Pacific herring (Clupea harengus pallasi) are important forage fish for marbled murrelets. Designated marbled murrelet critical habitat is located upriver from the project area, approximately 7 miles due east of the subject property. Marbled murrelets travel along rivers while flying to nesting areas and may be briefly present in the air above the South Fork of the Stillaguamish River. Oregon Spotted Frog Rana pretiosa - Threatened listed September 29, 2014 - Critical Habitat designated May 11, 2016 Oregon spotted frog is endemic to the Pacific Northwest and spend the majority of life in or near perennial bodies of water such as lakes, ponds, slow streams and marshes. Often, the Oregon spotted frog can be found in emergent wetlands with shallow, standing water. Warm, marshy areas are preferable, with an abundance of emergent or floating vegetation, which is used for cover and forging (Watson, et.al., 2000). Adult frogs are opportunistic predators that feed primarily on a wide variety of insects found in or near the water including, slugs, snails, spiders, crickets, grasshoppers, dragonflies, damselflies, beetles, butterflies, moths, flies, bees, ants and wasps. Within Washington, the Oregon spotted frog can be found in Whatcom, Skagit, and Skamania counties with larger populations found in Thurston and Klickitat. Historically, they were also found in Snohomish, King, Pierce and Clark counties. Breeding habitat features include low gradient shallows in emergent wetlands and seasonally flooded pastures dominated by wetland vegetation such as sedge and rushes, with low canopy cover and connectivity to summer habitat. Females may deposit egg masses at the same location for several successive years indicating some site fidelity (USFWS, 2014). The frogs typically start breeding at three years of age, and breeding occurs in February or March at low elevations and late May or early June in high elevations. Eggs will hatch within a few weeks and the larvae will metamorphose during their first summer. Tadpoles are grazers with tough tooth rows for scraping plant tissue. They will also consume algae and detritus (USFWS, 2014). In the summer months, adults will move to deeper, perennial pools close to breeding habitat. Summer habitats are dominated by wetland vegetation particularly hardhack, partially shaded by palustrine forest vegetation and are connected to winter habitats (WSDOT). In studies done on populations along the Cascade Mountains, most frogs will move less than 250 meters between summer and winter habitats (Pearl, 2018). During the fall rains, the frog will start to move to winter habitats which includes protected, aquatic areas that provide protection from predators and freezing. The winter habitats consist of unconsolidated bottom habitats, which include ponded, pooled areas with water depth greater than 6 inches. Here they bury themselves at the base of dense vegetation in shallow water under ice (Watson, 2003). 7.2 Direct and Short-Term Effects The proposed project actions have one mechanism for direct and short-term impacts to any ESA- listed species potentially present: a temporary increase in terrestrial noise caused by construction activities. Any turbidity impacts are expected to be temporary and constrained to the project area due to the conservation measures and BMPs that will be in place for the project. As such, there is no 1916.0001 â€“ Gilman Walk at Country Charm 30 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 potential for turbidity impacts to fish species. Any anticipated short-term effects are anticipated to be brief in time and space and not likely to negatively affect any local ESA-listed species. 7.3 Indirect Effects The proposed residential redevelopment may result in a net increase in impervious surfaces. However, the proposed project area was previously used for dairy farm operations and any change in impervious surface is anticipated to be minor due to the required stormwater infrastructure and enhanced water quality treatment proposed. Increases in impervious surfaces can change hydrologic dynamics through a decline in evapotranspiration and decreases in infiltration (NOAA, 2003). The projectâ€™s proposal will not likely have a measurable impact on the watershed or ESA-listed species. However, on a watershed scale cumulative actions that increase impervious surfaces can also have an overall negative impact on hydrology. Changes in hydrology from increases in impervious surfaces can reduce water infiltration and dilution. Urban runoff and discharges can increase loading of nutrients, bacteria, metals, pesticides, and other toxicants to streams (NOAA, 2003). In addition, changes in hydrology can increase frequency and severity of flooding, and accelerate channel erosion and streambed substrate disturbance (NOAA, 2003). During project construction, TESC measures and BMPs designed to control site runoff will minimize potential immediate effects to hydrology and water quality. The proposed stormwater infrastructure will be used to treat and detain stormwater runoff from the residential development. The proposed project does not propose to adversely affect any ESA-listed species. 7.4 Long-Term Effects The proposed grading and clearing activities associated with the residential construction and new maintenance access road will remove onsite vegetation; any areas temporarily impacted from these project elements will be reseeded as necessary. Long-term effects of the proposed project on habitat and species are expected to be extremely minimal due to the lack of existing functional habitat and the fact that the project is located in an urban and agricultural area; as such, no habitat isolation will occur. Any long-term effects from the increase in impervious surface are extremely discountable and will have no negative effect on functionality of the floodplain area or on critical habitat or species. 7.5 Conservation Measures and Best Management Practices Project BMPs include TESC measures consisting of silt fencing, seeding of disturbed soils, and items outlined in the projectâ€™s erosion and stormwater control plans, to be prepared by the Project Engineer prior to clearing and grading activities as applicable. Once TESC measures are in place, construction actions will proceed. Equipment used for construction activities will be typical for excavation and grading activities and will be kept in good working order free of leaks. All equipment staging and materials stockpiles will be kept in upland areas, away from wetlands and floodplains, and the areas will be kept free of spills and/or hazardous materials. A concrete wash water collection basin or similar should also be installed away from the shoreline, floodplain, and wetland areas prior to commencement of construction activities requiring additional concrete work. Any fill material if necessary should be sourced from areas onsite or from approved suppliers and will be free of pollutants and hazardous materials. 1916.0001 â€“ Gilman Walk at Country Charm 31 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Once construction is complete, any disturbed, undeveloped upland areas will be revegetated using appropriate native plants determined by the development manager. These actions will take place to permanently stabilize the soils and reduce erosion and restore any disturbed native vegetation to maintain a no net loss of ecological function. 7.6 Determinations of Effect 7.6.1 Critical Habitat Critical Habitat is defined in Section 3 of the ESA as: (1) The specific areas within the geographical area occupied by the species, at the time it is listed in accordance with the Act, on which are found those physical or biological features (a) essential to the conservation of the species and (b) which may require special management considerations or protection, and (2) Specific areas outside the geographical area occupied by the species at the time it is listed, upon a determination such areas are essential for the conservation of the species. Critical Habitat for a listed species contains Primary Constituent Elements (PCEâ€™s), as defined below. 7.6.2 Primary Constituent Elements In accordance with Section 3(5)(A)(i) of the ESA, and regulations at 50 CFR 424.12(b), in determining which areas were occupied at the time of listing to propose a Critical Habitat, we consider the physical or biological features essential to the conservation of the species and that may require special management considerations or protection. These features are the PCEâ€™s laid out in the appropriate quantity and spatial arrangement for conservation of the species. These include, but are not limited to: (1) space for individual and population growth for normal behavior; (2) food, water, air, light, minerals, or other nutritional or physiological requirements; (3) cover or shelter; (4) sites for breeding, reproduction, or rearing (or development) of offspring; and (5) habitats that are protected from disturbance or are representative of the historical, geographical, and ecological distributions of a species. Pacific Salmon and Steelhead Oncorhynchus tshawytscha, Oncorhynchus keta, Oncorhynchus mykiss All PCEs for Pacific salmon and steelhead require adequate water quantity and quality conditions to support salmon in the relevant life stage(s). These PCEs can be generally described to include the following: (1) Freshwater spawning sites with substrate supporting spawning, incubation and larval development; (2) Freshwater rearing sites with floodplain connectivity, forage supporting juvenile development, and natural cover; (3) Freshwater migration corridors free of obstruction with natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, side channels, and undercut banks supporting juvenile and adult mobility and survival; (4) Estuarine areas free of obstruction with salinity conditions supporting juvenile and adult physiological transitions between fresh- and saltwater; natural cover and juvenile and adult forage, including aquatic invertebrates and fishes, supporting growth and maturation, (5) Nearshore marine areas free of obstruction with forage, including aquatic invertebrates and fishes, supporting growth and maturation; natural cover, and (6) Offshore marine areas with forage, including aquatic invertebrates and fishes, supporting growth and maturation. Within these areas, essential features of critical habitat include adequate substrate, water quality, water quantity, water temperature, water velocity, cover, shelter, food, riparian vegetation, space, and safe passage conditions.

The following paragraphs discuss the proposed project impact determinations on ESA-listed species and corresponding critical habitat. Bull Trout Salvelinus confluentus Habitat features required by bull trout are similar to those needed by salmonids. These features include (1) Springs, seeps, groundwater sources, and subsurface water connectivity (hyporheic flows) to contribute to water quality and quantity and provide thermal refugia; (2) accessible migratory corridors; (3) persistent and abundant food sources; (4) habitat complexity and processes that establish and maintain these aquatic environments, with features such as large wood, side channels, pools, undercut banks and unembedded substrates; (5) water temperatures between 36 and 59 degrees Fahrenheit; (6) adequate amount, composition and size of substrate with minimal fine sediment; (7) a naturally fluctuating hydrograph; (8) sufficient water quality and quantity; and (9) sufficiently low levels of nonnative predation, interbreeding or competition.

Puget Sound Steelhead Trout and Critical Habitat Oncorhynchus mykiss Puget Sound steelhead trout presence is documented by the WDFW SalmonScape mapping tool in the South Fork of the Stillaguamish River, along the northwest portion of the subject property. The offsite drainage is not likely, but may be used as off-channel habitat. Temporary increases in terrestrial noise are not expected to have any effect on fish species. No turbidity impacts are proposed within suitable salmonid habitat, and the proposed project will implement BMPs and TESC measures to limit construction runoff from the site. The proposed stormwater treatment system is expected to treat runoff from new impervious surfaces in order to meet water quality standards. Due to the lack of direct impacts to steelhead habitat and the proposed treatment of stormwater from new, minor impervious surfaces, it is anticipated the proposed project actions May Affect, But Are Not Likely to Adversely Affect Puget Sound Steelhead. The Action Area does not include critical habitat; therefore, the proposed activities will have No Effect on Puget Sound Steelhead Critical Habitat. 1916.0001 â€“ Gilman Walk at Country Charm 33 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Puget Sound Chinook Salmon and Critical Habitat Oncorhynchus tshawytscha Puget Sound chinook salmon presence is documented by the WDFW SalmonScape mapping tool in the South Fork of the Stillaguamish River, along the northwest portion of the subject property. The offsite drainage is not likely, but may be used as off-channel habitat. Temporary increases in terrestrial noise are not expected to have any effect on fish species. No turbidity impacts are proposed within suitable salmonid habitat, and the proposed project will implement BMPs and TESC measures to limit construction runoff from the site. The proposed stormwater treatment system is expected to treat runoff from new impervious surfaces in order to meet water quality standards. Due to the lack of direct impacts to chinook habitat and the proposed treatment of stormwater from new, minor impervious surfaces, it is anticipated the proposed project actions May Affect, But Are Not Likely to Adversely Affect Puget Sound Chinook. The Action Area does not include critical habitat; therefore, the proposed activities will have No Effect on Puget Sound Chinook Critical Habitat. Bull Trout and Critical Habitat Salvelinus confluentus Puget Sound chinook salmon presence is documented by the WDFW SalmonScape mapping tool in the South Fork of the Stillaguamish River, along the northwest portion of the subject property. The offsite drainage is not likely, but may be used as off-channel habitat. Temporary increases in terrestrial noise are not expected to have any effect on fish species.

Due to the lack of direct impacts to chinook habitat and the proposed treatment of stormwater from new, minor impervious surfaces, it is anticipated the proposed project actions May Affect, But Are Not Likely to Adversely Affect Bull Trout. The Action Area does not include critical habitat; therefore, the proposed activities will have No Effect on Bull Trout Critical Habitat. Marbled Murrelet Brachyramphus marmoratus Marbled murrelet critical habitat has been identified upriver from the subject property, approximately 7 miles due east of the subject property, and marbled murrelets may pass through the Action Area during nesting season. Habitat within the Action Area consists primarily of mixed residential and agricultural landscapes that do not provide suitable habitat for marbled murrelet. Any noise impacts are expected to be temporary and occur within the limited area of the Action Area. Marbled murrelet are rare within Puget Sound, and their presence over the Action Area is unlikely. Due to limitation of noise impacts and the small likelihood of marbled murrelet presence in the Action Area, the proposed project actions May Affect, But Are Not Likely to Adversely Affect Marbled Murrelet. Oregon Spotted Frog Rana pretiosa The onsite wetlands likely provide suitable habitat for Oregon spotted frog as these wetlands contain emergent and aquatic bed vegetation. However, the subject property is surrounded by residential and agricultural landscapes and the WDFW PHS map does not identify documented populations of Oregon spotted frog near the subject property. Due to the lack of landscape connectivity to a documented population, Oregon spotted frog presence is extremely unlikely. No direct wetland impacts are proposed, and the proposed project actions May Affect, But Are Not Likely to Adversely Affect Oregon Spotted Frog. 1916.0001 â€“ Gilman Walk at Country Charm 34 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 7.7 Essential Fish Habitat Analysis The Magnuson-Stevens Fishery and Conservation Act (MSA) and the Sustainable Fisheries Act of 1996 (SFA)(Public Law 104-267) require Federal agencies to consult with NMFS on activities that may adversely affect Essential Fish Habitat (EFH). EFH is defined by the MSA in 50 CFR 600.905- 930 as â€œthose waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity.â€ The object of this EFH assessment is to notify NMFS of the project and potential effects and determine whether or not the proposed actions â€œmay adversely affectâ€ designated EFH for relevant commercial, federally-managed fisheries species within the proposed Action Area. It also describes conservation measures proposed to avoid, minimize, or otherwise offset potential adverse effects to designated EFH resulting from the proposed action. The following EFH analysis is provided in conjunction with ESA consultation; some previous sections of the document may be referenced in order to reduce redundancies. The proposed project actions are detailed in Section 2.2 of this report. Discussion of impacts to EFH for relevant species follows. Salmon EFH Salmonid presence is documented by the WDFW SalmonScape mapping tool in the South Fork of the Stillaguamish River, along the northwest portion of the subject property. The offsite drainage may be used as off-channel habitat, but given the condition and water quality of the drainage, usage is unlikely. No turbidity impacts are proposed within suitable salmonid habitat, and the proposed project will implement BMPs and TESC measures to limit construction runoff from the site. The proposed actions will result in creation of impervious surfaces onsite; however, runoff from these surfaces will be directed towards the stormwater treatment system. Due to the lack of impacts to suitable salmonid habitat, use of BMPs, and installation of stormwater detention and enhanced treatment infrastructure, the proposed project Will Not Adversely Affect Salmon EFH. Conclusions Conservation measures that are incorporated into the project are expected to reduce the potential effects of this project as discussed in Section 7.5. Terrestrial noise will have no effect on ESA-listed fish habitat or species, turbidity is expected to be localized and temporary, and any other impacts will be mitigated. Project actions described in Section 2.2 and completion of the project will not adversely affect the EFH for salmonid species. 1916.0001 â€“ Gilman Walk at Country Charm 35 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 8. Closure The findings and conclusions documented in this report have been prepared for specific application to this project. They have been developed in a manner consistent with that level of care and skill normally exercised by members of the environmental science profession currently practicing under similar conditions in the area. Our work was also performed in accordance with the terms and conditions set forth in our proposal. The conclusions and recommendations presented in this report are professional opinions based on an interpretation of information currently available to us and are made within the operation scope, budget, and schedule of this project. No warranty, expressed or implied, is made. In addition, changes in government codes, regulations, or laws may occur. Due to such changes, our observations and conclusions applicable to this project may need to be revised wholly or in part. All wetland boundaries identified by SVC are based on conditions present at the time of the site inspection and considered preliminary until the flagged wetland boundaries are validated by the jurisdictional agencies. Validation of the wetland boundaries by the regulating agency provides a certification, usually written, that the wetland boundaries verified are the boundaries that will be regulated by the agencies until a specific date or until the regulations are modified. Only the regulating agencies can provide this certification. As wetlands are dynamic communities affected by both natural and human activities, changes in wetland boundaries may be expected; therefore, wetland delineations cannot remain valid for an indefinite period of time. Local agencies typically recognize the validity of wetland delineations for a period of five years after completion of a wetland delineation report. Development activities on a site five years after the completion of this wetland delineation report may require revision of the wetland delineation. In addition, changes in government codes, regulations, or laws may occur. Due of such changes, our observations and conclusions applicable to this site may need to be revised wholly or in part. 1916.0001 â€“ Gilman Walk at Country Charm 36 Soundview Consultants LLC Wetland & Fish & Wildlife Habitat Assessment & FEMA ESA Biological Assessment November 18, 2019 Chapter 9.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO â€“ go to 2 YES â€“ the wetland class is Tidal Fringe â€“ go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO â€“ Saltwater Tidal Fringe (Estuarine) YES â€“ Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO â€“ go to 3 YES â€“ The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO â€“ go to 4 YES â€“ The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO â€“ go to 5 YES â€“ The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update 3 Rating Form â€“ Effective January 1, 2015 Wetland name or number ______A NO â€“ go to 6 YES â€“ The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO â€“ go to 7 YES â€“ The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO â€“ go to 8 YES â€“ The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO â€“ go to 2 YES â€“ the wetland class is Tidal Fringe â€“ go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO â€“ Saltwater Tidal Fringe (Estuarine) YES â€“ Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO â€“ go to 3 YES â€“ The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO â€“ go to 4 YES â€“ The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO â€“ go to 5 YES â€“ The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update 3 Rating Form â€“ Effective January 1, 2015 Wetland name or number ______B NO â€“ go to 6 YES â€“ The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO â€“ go to 7 YES â€“ The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO â€“ go to 8 YES â€“ The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

NO â€“ go to 4 YES â€“ The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO â€“ go to 5 YES â€“ The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update 3 Rating Form â€“ Effective January 1, 2015 Wetland name or number ______C NO â€“ go to 6 YES â€“ The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO â€“ go to 7 YES â€“ The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO â€“ go to 8 YES â€“ The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Table 1 â€“ Summary of Site Pollutant Constituents Constituent Location Depth Concentration (Pollutant) N/A N/A N/A N/A Gilman Walk at Country Charm Page 1-1 1.2 Proposed Construction Activities The Gilman Walk at Country Charm project is a multi-family development consisting of residential buildings and associated roads, utilities, parking, and open space area. The proposed development will include clearing and grading of the existing site for the construction of the building and utilities, stormwater and water quality facilities, and paved roads. The remaining undeveloped site area will be landscaped. Contaminated Site Information: N/A Gilman Walk at Country Charm Page 1-2 2 Construction Stormwater Best Management Practices (BMPs) The SWPPP is a living document reflecting current conditions and changes throughout the life of the project. These changes may be informal (i.e., hand-written notes and deletions). Update the SWPPP when the CESCL has noted a deficiency in BMPs or deviation from original design. 2.1 The 13 Elements 2.1.1 Element 1: Preserve Vegetation / Mark Clearing Limits Clearing limits have been delineated on sheets C2.01-C2.03 of the civil plans. â€¢ High Visibility Plastic or Metal Fence: BMP C103 2.1.2 Element 2: Establish Construction Access A construction access is proposed per STD. 2-9 of the Lynnwood standard details. â€¢ Stabilized Construction Entrance/Exit: BMP C105 Street washing is not permitted, even after shoveling or sweeping. During construction, if material is being deposited on off-site streets, additional strategies may be required including: Regenerative-type vacuum sweepers and repeated or continuous sweeping. Wheel wash (or an improved wheel wash if one already exists). Special site procedures and provisions (such as transferring haul-outs to trucks that travel only on paved and maintained surfaces in the site). Suspension of work until dry weather. 2.1.3 Element 3: Control Flow Rates During construction and before installation and operation of the permanent conveyance system, the contractor shall construct temporary sediment ponds to provide temporary storage and avoid turbid water discharge. If necessary, the contractor shall be prepared to bring temporary storm water storage tanks such as Baker Tanks, or similar to provide supplemental temporary storage as determined by the City inspector. The necessity and siting of temporary tanks shall be coordinated with the City inspector. â€¢ Sediment Trap (BMP C240) Will you construct stormwater retention and/or detention facilities? Yes No Will you use permanent infiltration ponds or other low impact development (example: rain gardens, bio-retention, porous pavement) to control flow during construction? Yes No Gilman Walk at Country Charm Page 2-1 2.1.4 Element 4: Install Sediment Controls Silt fence, inlet protection and sediment ponds will be installed as shown on and detailed on sheets C2.01-C2.03 and C2.31 of civil plans. If the standards are not being met, additional BMPs (including site-specific designs) shall be implemented. If additional BMPs are not implemented or are not successful, work may be suspended until the City approves a new SWPPP (see Vol. II: 2.3). â€¢ Storm Drain Inlet Protection (BMP C220) â€¢ Silt Fence (BMP C233) â€¢ Interceptor Dike and Swale (BMP C200) 2.1.5 Element 5: Stabilize Soils All exposed and unworked soils shall be stabilized by application of effective BMPs that protect the soil from the erosive forces of raindrop impact, flowing water, and wind throughout the life of the project. As such, no soils shall remain exposed and unworked for more than 7 days during the dry season (May 1 to September 30) and 2 days during the wet season (October 1 to April 30). Regardless of the time of year, all soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on weather forecasts. In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be temporarily covered with plastic sheeting. All stockpiled soils shall be stabilized from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels. All projects must implement BMP T5.13 Post Construction Soil Quality and Depth. â€¢ Temporary and Permanent Seeding (BMP C120) â€¢ Mulching (BMP C121) â€¢ Plastic Covering (BMP C123) â€¢ Sodding (BMP C124) â€¢ Topsoiling/Composting C125 â€¢ Dust Control (BMP C140) West of the Cascade Mountains Crest Number of Days Soils Can Season Dates be Left Exposed During the Dry Season May 1 â€“ September 30 7 days During the Wet Season October 1 â€“ April 30 2 days Anticipated project dates: TBD End date: TBD Will you construct during the wet season? Yes No Gilman Walk at Country Charm Page 2-2 2.1.6 Element 6: Protect Slopes All cut and fill slopes will be designed, constructed, and protected in a manner that minimizes erosion. Clearing/grading work shall comply with the Stormwater Manual, geotechnical recommendations, SEPA (State Environmental Policy Act) conditions, and other applicable regulations and standards. These project-specific requirements are in addition to and take priority over general standards. â€¢ Temporary and Permanent Seeding (BMP C120) â€¢ Plastic Covering (BMP C123) Will steep slopes be present at the site during construction? Yes No 2.1.7 Element 7: Protect Drain Inlets All downstream storm drain inlets shall be protected to prevent sediment-laden drainage from entering the storm drainage conveyance system. See sheets C2.01-C2.03 and C2.31 of the civil plans for locations of Filter Fabric Protection for CBâ€™s (Storm Drain Inlet Protection). However, the first priority is to keep all access roads clean of sediment and keep street wash water separate from entering storm drains until treatment can be provided. The Contractor shall remove inlet protection at the end of the project without releasing captured sediment into the storm system. â€¢ Storm Drain Inlet Protection (BMP C220) 2.1.8 Element 8: Stabilize Channels and Outlets Outlets discharging to open channels will have necessary outfall protection installed to prevent scour and erosion. Rock check dams will be installed as necessary. No outlets are proposed to discharge to open channels for this project. Temporary conveyance channels shall be stabilized for the 10-year, 24-hour frequency storm, and assuming full build out of tributary area(s). â€¢ Check Dams (BMP C207) â€¢ Interceptor Dike and Swale (BMP C200) 2.1.9 Element 9: Control Pollutants All pollutants, including waste materials and demolition debris, that occur onsite shall be handled and disposed of in a manner that does not cause contamination of storm water. The site is located in critical aquifer area. Therefore, refueling activities and hazardous materials will not happen onsite. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean, well-organized, and free of debris. If required, BMPs to be implemented to control specific sources of pollutants are discussed below. Vehicles, construction equipment, and/or petroleum product storage/dispensing: Gilman Walk at Country Charm Page 2-3 ï‚§ All vehicles and equipment will be inspected regularly to detect any leaks or spills, and to identify maintenance needs to prevent leaks or spills. ï‚§ Fueling of tanks and petroleum product storage activates will not be performed on the site. ï‚§ Repair and maintenance of vehicles or equipment will be located at offsite facilities. ï‚§ In order to perform emergency repairs on site, temporary plastic will be placed beneath and, if raining, over the vehicle. ï‚§ Contaminated surfaces shall be cleaned immediately following any discharge or spill incident. Chemical storage: ï‚§ Any chemicals stored in the construction areas will conform to the appropriate source control BMPs listed in Volume IV of the Ecology stormwater manual. Hazardous materials will be stored offsite. In Western WA, all chemicals shall have cover, containment, and protection provided on site, per BMP C153 for Material Delivery, Storage and Containment in SWMMWW 2014. ï‚§ Application of agricultural chemicals, including fertilizers and pesticides, shall be conducted in a manner and at application rates that will not result in loss of chemical to stormwater runoff. Manufacturersâ€™ recommendations for application procedures and rates shall be followed. Excavation and tunneling spoils dewatering waste: ï‚§ Dewatering BMPs and BMPs specific to the excavation and tunneling (including handling of contaminated soils) are discussed under Element 10. Demolition: ï‚§ Dust released from demolished sidewalks, buildings, or structures will be controlled using Dust Control measures (BMP C140). ï‚§ Storm drain inlets vulnerable to stormwater discharge carrying dust, soil, or debris will be protected using Storm Drain Inlet Protection (BMP C220 as described above for Element 7). ï‚§ Process water and slurry resulting from sawcutting and surfacing operations will be prevented from entering the waters of the State by implementing Sawcutting and Surfacing Pollution Prevention measures (BMP C152). Concrete and grout: ï‚§ Process water and slurry resulting from concrete work will be prevented from entering the waters of the State by implementing Concrete Handling measures (BMP C151). ï‚§ Due to site constraints a Concrete Washout Area (BMP C154) is impractical and all trucks will be washed out offsite at the batch plant. Sanitary wastewater: Gilman Walk at Country Charm Page 2-4 ï‚§ Portable sanitation facilities will be firmly secured, regularly maintained, and emptied when necessary. ï‚§ Wheel wash or tire bath wastewater shall be discharged to a separate on-site treatment system or to the sanitary sewer as part of Wheel Wash implementation (BMP C106). Solid Waste: ï‚§ Solid waste will be stored in secure, clearly marked containers. Other: ï‚§ Other BMPs will be administered as necessary to address any additional pollutant sources on site which may include but not limited to the following: ï‚§ Fire hydrant and water main flushing following pressure testing and purification ï‚§ Cleaning of foundation panels following concrete pours, slurry mixes from the spoils of the concrete truck ï‚§ Flushing of newly installed irrigation systems ï‚§ Washing of pavement for stripping. ï‚§ Construction workers washing tools following installation. If required, BMPs to be implemented to control specific sources of pollutants are listed below: â€¢ Concrete Handling (BMP C151) â€¢ Sawcutting and Surfacing Pollution Prevention (BMP C152) â€¢ Storm Drain Inlet Protection (BMP C220) Table 2 â€“ BMP Implementation Schedule Pollutant (List pollutants and source, if applicable) N/A Will maintenance, fueling, and/or repair of heavy equipment and vehicles occur on-site? Yes No Will wheel wash or tire bath system BMPs be used during construction? Yes No Will pH-modifying sources be present on-site? Yes No Table 3 â€“ pH-Modifying Sources None Bulk cement Cement kiln dust Gilman Walk at Country Charm Page 2-5 Fly ash Other cementitious materials New concrete washing or curing waters Waste streams generated from concrete grinding and sawing Exposed aggregate processes Dewatering concrete vaults Concrete pumping and mixer washout waters Recycled concrete Recycled concrete stockpiles Other (i.e., calcium lignosulfate) [please describe: ] Concrete trucks must not be washed out onto the ground, or into storm drains, open ditches, streets, or streams. Excess concrete must not be dumped on-site, except in designated concrete washout areas with appropriate BMPs installed. Will uncontaminated water from water-only based shaft drilling for construction of building, road, and bridge foundations be infiltrated provided the wastewater is managed in a way that prohibits discharge to surface waters? Yes No 2.1.10 Element 10: Control Dewatering Any dewatering water from trenches or foundations shall be discharged into a controlled conveyance system before discharge to a temporary sediment pond. Only clean, non-turbid water shall be discharged into Waters of the State, and the discharge must not cause erosion or flooding of receiving waters. Highly turbid or contaminated dewatering water shall be handled separately- transported offsite to a legal disposal site, or for small volumes of localized dewatering, to a sedimentation bag with outfall to a ditch. This SWPPP will be updated to reflect any BMPs used. Table 4 â€“ Dewatering BMPs Infiltration Transport off-site in a vehicle (vacuum truck for legal disposal) Ecology-approved on-site chemical treatment or other suitable treatment technologies Sanitary or combined sewer discharge with local sewer district approval (last resort) Use of sedimentation bag with discharge to ditch or swale (small volumes of localized dewatering) 2.1.11 Element 11: Maintain BMPs All temporary and permanent Erosion and Sediment Control (ESC) BMPs shall be maintained and repaired as needed to ensure continued performance of their intended function. Gilman Walk at Country Charm Page 2-6 Maintenance and repair shall be conducted in accordance with each particular BMP specification (see Volume II of the SWMMWW or Chapter 7 of the SWMMEW). Visual monitoring of all BMPs installed at the site will be conducted at least once every calendar week and within 24 hours of any stormwater or non-stormwater discharge from the site. If the site becomes inactive and is temporarily stabilized, the inspection frequency may be reduced to once every calendar month. All temporary ESC BMPs shall be removed within 30 days after final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped sediment shall be stabilized on-site or removed. Disturbed soil resulting from removal of either BMPs or vegetation shall be permanently stabilized. Additionally, protection must be provided for all BMPs installed for the permanent control of stormwater from sediment and compaction. BMPs that are to remain in place following completion of construction shall be examined and restored to full operating condition. If sediment enters these BMPs during construction, the sediment shall be removed and the facility shall be returned to conditions specified in the construction documents. 2.1.12 Element 12: Manage the Project The project will be managed based on the following principles: â€¢ Projects will be phased to the maximum extent practicable and seasonal work limitations will be taken into account. â€¢ Inspection and monitoring: o Inspection, maintenance and repair of all BMPs will occur as needed to ensure performance of their intended function. o Site inspections and monitoring will be conducted in accordance with Special Condition S4 of the CSWGP. Sampling locations are indicated on the Site Map. Sampling station(s) are located in accordance with applicable requirements of the CSWGP. â€¢ Maintain an updated SWPPP. o The SWPPP will be updated, maintained, and implemented in accordance with Special Conditions S3, S4, and S9 of the CSWGP. As site work progresses the SWPPP will be modified routinely to reflect changing site conditions. The SWPPP will be reviewed monthly to ensure the content is current.

Gilman Walk at Country Charm Page 3-2 3.2.2 pH Sampling pH monitoring is required for â€œSignificant concrete workâ€ (i.e., greater than 1000 cubic yards poured concrete over the life of the project). The use of recycled concrete or engineered soils (soil amendments including but not limited to Portland cement-treated base [CTB], cement kiln dust [CKD] or fly ash) also requires pH monitoring. For significant concrete work, pH sampling will start the first day concrete is poured and continue until it is cured, typically three (3) weeks after the last pour. For engineered soils and recycled concrete, pH sampling begins when engineered soils or recycled concrete are first exposed to precipitation and continues until the area is fully stabilized. If the measured pH is 8.5 or greater, the following measures will be taken: 1. Prevent high pH water from entering storm sewer systems or surface water. 2. Adjust or neutralize the high pH water to the range of 6.5 to 8.5 su using appropriate technology such as carbon dioxide (CO2) sparging (liquid or dry ice). 3. Written approval will be obtained from Ecology prior to the use of chemical treatment other than CO2 sparging or dry ice.

BMP Detail BMP C103: High Visibility Fence Purpose Fencing is intended to: 1. Restrict clearing to approved limits. 2. Prevent disturbance of sensitive areas, their buffers, and other areas required to be left undisturbed. 3. Limit construction traffic to designated construction entrances, exits, or internal roads. 4. Protect areas where marking with survey tape may not provide adequate protection. Conditions of Use To establish clearing limits plastic, fabric, or metal fence may be used: â€¢ At the boundary of sensitive areas, their buffers, and other areas required to be left uncleared. â€¢ As necessary to control vehicle access to and on the site. Design and High visibility plastic fence shall be composed of a high-density Installation polyethylene material and shall be at least four feet in height. Posts for Specifications the fencing shall be steel or wood and placed every 6 feet on center (maximum) or as needed to ensure rigidity. The fencing shall be fastened to the post every six inches with a polyethylene tie. On long continuous lengths of fencing, a tension wire or rope shall be used as a top stringer to prevent sagging between posts. The fence color shall be high visibility orange. The fence tensile strength shall be 360 lbs./ft. using the ASTM D4595 testing method. If appropriate install fabric silt fence in accordance with BMP C233 to act as high visibility fence. Silt fence shall be at least 3 feet high and must be highly visible to meet the requirements of this BMP. Metal fences shall be designed and installed according to the manufacturer's specifications. Metal fences shall be at least 3 feet high and must be highly visible. Fences shall not be wired or stapled to trees. Maintenance If the fence has been damaged or visibility reduced, it shall be repaired or Standards replaced immediately and visibility restored. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C105: Stabilized Construction Entrance / Exit Purpose Stabilized Construction entrances are established to reduce the amount of sediment transported onto paved roads by vehicles or equipment. This is done by constructing a stabilized pad of quarry spalls at entrances and exits for construction sites. Conditions of Use Construction entrances shall be stabilized wherever traffic will be entering or leaving a construction site if paved roads or other paved areas are within 1,000 feet of the site. For residential construction provide stabilized construction entrances for each residence, rather than only at the main subdivision entrance. Stabilized surfaces shall be of sufficient length/width to provide vehicle access/parking, based on lot size/configuration. On large commercial, highway, and road projects, the designer should include enough extra materials in the contract to allow for additional stabilized entrances not shown in the initial Construction SWPPP. It is difficult to determine exactly where access to these projects will take place; additional materials will enable the contractor to install them where needed. Design and See Figure 4.1.1 for details. Note: the 100â€™ minimum length of the Installation entrance shall be reduced to the maximum practicable size when the size Specifications or configuration of the site does not allow the full length (100â€™). Construct stabilized construction entrances with a 12-inch thick pad of 4- inch to 8-inch quarry spalls, a 4-inch course of asphalt treated base (ATB), or use existing pavement. Do not use crushed concrete, cement, or calcium chloride for construction entrance stabilization because these products raise pH levels in stormwater and concrete discharge to surface waters of the State is prohibited. A separation geotextile shall be placed under the spalls to prevent fine sediment from pumping up into the rock pad. The geotextile shall meet the following standards: Grab Tensile Strength (ASTM D4751) 200 psi min. Grab Tensile Elongation (ASTM 30% max. D4632) Mullen Burst Strength (ASTM 400 psi min. D3786-80a) AOS (ASTM D4751) 20-45 (U.S. standard sieve size) â€¢ Consider early installation of the first lift of asphalt in areas that will paved; this can be used as a stabilized entrance. Also consider the installation of excess concrete as a stabilized entrance. During large concrete pours, excess concrete is often available for this purpose. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Fencing (see BMP C103) shall be installed as necessary to restrict traffic to the construction entrance. â€¢ Whenever possible, the entrance shall be constructed on a firm, compacted subgrade. This can substantially increase the effectiveness of the pad and reduce the need for maintenance. â€¢ Construction entrances should avoid crossing existing sidewalks and back of walk drains if at all possible. If a construction entrance must cross a sidewalk or back of walk drain, the full length of the sidewalk and back of walk drain must be covered and protected from sediment leaving the site. Maintenance Quarry spalls shall be added if the pad is no longer in accordance with Standards the specifications. â€¢ If the entrance is not preventing sediment from being tracked onto pavement, then alternative measures to keep the streets free of sediment shall be used. This may include replacement/cleaning of the existing quarry spalls, street sweeping, an increase in the dimensions of the entrance, or the installation of a wheel wash. â€¢ Any sediment that is tracked onto pavement shall be removed by shoveling or street sweeping. The sediment collected by sweeping shall be removed or stabilized on site. The pavement shall not be cleaned by washing down the street, except when high efficiency sweeping is ineffective and there is a threat to public safety. If it is necessary to wash the streets, the construction of a small sump to contain the wash water shall be considered. The sediment would then be washed into the sump where it can be controlled. â€¢ Perform street sweeping by hand or with a high efficiency sweeper. Do not use a non-high efficiency mechanical sweeper because this creates dust and throws soils into storm systems or conveyance ditches. â€¢ Any quarry spalls that are loosened from the pad, which end up on the roadway shall be removed immediately. â€¢ If vehicles are entering or exiting the site at points other than the construction entrance(s), fencing (see BMP C103) shall be installed to control traffic. â€¢ Upon project completion and site stabilization, all construction accesses intended as permanent access for maintenance shall be permanently stabilized.

The products are available for review on Ecologyâ€™s website at http://www.ecy.wa.gov/programs/wq/stormwater/newtech/equivalent.html FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C120: Temporary and Permanent Seeding Purpose Seeding reduces erosion by stabilizing exposed soils. A well-established vegetative cover is one of the most effective methods of reducing erosion. Conditions of Use Use seeding throughout the project on disturbed areas that have reached final grade or that will remain unworked for more than 30 days. The optimum seeding windows for western Washington are April 1 through June 30 and September 1 through October 1. Between July 1 and August 30 seeding requires irrigation until 75 percent grass cover is established. Between October 1 and March 30 seeding requires a cover of mulch with straw or an erosion control blanket until 75 percent grass cover is established. Review all disturbed areas in late August to early September and complete all seeding by the end of September. Otherwise, vegetation will not establish itself enough to provide more than average protection. â€¢ Mulch is required at all times for seeding because it protects seeds from heat, moisture loss, and transport due to runoff. Mulch can be applied on top of the seed or simultaneously by hydroseeding. See BMP C121: Mulching for specifications. â€¢ Seed and mulch, all disturbed areas not otherwise vegetated at final site stabilization. Final stabilization means the completion of all soil disturbing activities at the site and the establishment of a permanent vegetative cover, or equivalent permanent stabilization measures (such as pavement, riprap, gabions, or geotextiles) which will prevent erosion. Design and Seed retention/detention ponds as required. Installation Install channels intended for vegetation before starting major Specifications earthwork and hydroseed with a Bonded Fiber Matrix. For vegetated channels that will have high flows, install erosion control blankets over hydroseed. Before allowing water to flow in vegetated channels, establish 75 percent vegetation cover. If vegetated channels cannot be established by seed before water flow; install sod in the channel bottomâ€”over hydromulch and erosion control blankets. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Confirm the installation of all required surface water control measures to prevent seed from washing away. â€¢ Hydroseed applications shall include a minimum of 1,500 pounds per acre of mulch with 3 percent tackifier. See BMP C121: Mulching for specifications. â€¢ Areas that will have seeding only and not landscaping may need compost or meal-based mulch included in the hydroseed in order to establish vegetation. Re-install native topsoil on the disturbed soil surface before application. â€¢ When installing seed via hydroseeding operations, only about 1/3 of the seed actually ends up in contact with the soil surface. This reduces the ability to establish a good stand of grass quickly. To overcome this, consider increasing seed quantities by up to 50 percent. â€¢ Enhance vegetation establishment by dividing the hydromulch operation into two phases: 1. Phase 1- Install all seed and fertilizer with 25-30 percent mulch and tackifier onto soil in the first lift. 2. Phase 2- Install the rest of the mulch and tackifier over the first lift. Or, enhance vegetation by: 1. Installing the mulch, seed, fertilizer, and tackifier in one lift. 2. Spread or blow straw over the top of the hydromulch at a rate of 800-1000 pounds per acre. 3. Hold straw in place with a standard tackifier. Both of these approaches will increase cost moderately but will greatly improve and enhance vegetative establishment. The increased cost may be offset by the reduced need for: â€¢ Irrigation. â€¢ Reapplication of mulch. â€¢ Repair of failed slope surfaces. This technique works with standard hydromulch (1,500 pounds per acre minimum) and BFM/MBFMs (3,000 pounds per acre minimum). â€¢ Seed may be installed by hand if: â€¢ Temporary and covered by straw, mulch, or topsoil. â€¢ Permanent in small areas (usually less than 1 acre) and covered with mulch, topsoil, or erosion blankets. â€¢ The seed mixes listed in the tables below include recommended mixes for both temporary and permanent seeding. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Apply these mixes, with the exception of the wetland mix, at a rate of 120 pounds per acre. This rate can be reduced if soil amendments or slow-release fertilizers are used. â€¢ Consult the local suppliers or the local conservation district for their recommendations because the appropriate mix depends on a variety of factors, including location, exposure, soil type, slope, and expected foot traffic. Alternative seed mixes approved by the local authority may be used. â€¢ Other mixes may be appropriate, depending on the soil type and hydrology of the area. â€¢ Table 4.1.2 lists the standard mix for areas requiring a temporary vegetative cover.

Hydroseeding Guide Wetlands Seed Mix â€¢ Table 4.1.7 lists a recommended meadow seed mix for infrequently maintained areas or non-maintained areas where colonization by native plants is desirable. Likely applications include rural road and utility right-of-way. Seeding should take place in September or very early October in order to obtain adequate establishment prior to the winter months. Consider the appropriateness of clover, a fairly invasive species, in the mix. Amending the soil can reduce the need for clover.

Roughen all soil no matter what the slope. Track walk slopes before seeding if engineering purposes require compaction. Backblading or smoothing of slopes greater than 4H:1V is not allowed if they are to be seeded. â€¢ Restoration-based landscape practices require deeper incorporation than that provided by a simple single-pass rototilling treatment. Wherever practical, initially rip the subgrade to improve long-term permeability, infiltration, and water inflow qualities. At a minimum, permanent areas shall use soil amendments to achieve organic matter and permeability performance defined in engineered soil/landscape systems. For systems that are deeper than 8 inches complete the rototilling process in multiple lifts, or prepare the engineered soil system per specifications and place to achieve the specified depth. â€¢ Fertilizers: â€¢ Conducting soil tests to determine the exact type and quantity of fertilizer is recommended. This will prevent the over-application of fertilizer. â€¢ Organic matter is the most appropriate form of fertilizer because it provides nutrients (including nitrogen, phosphorus, and potassium) in the least water-soluble form. â€¢ In general, use 10-4-6 N-P-K (nitrogen-phosphorus-potassium) fertilizer at a rate of 90 pounds per acre. Always use slow-release fertilizers because they are more efficient and have fewer environmental impacts. Do not add fertilizer to the hydromulch machine, or agitate, more than 20 minutes before use. Too much agitation destroys the slow-release coating. â€¢ There are numerous products available that take the place of chemical fertilizers. These include several with seaweed extracts that are beneficial to soil microbes and organisms. If 100 percent cottonseed meal is used as the mulch in hydroseed, chemical fertilizer may not be necessary. Cottonseed meal provides a good source of long-term, slow-release, available nitrogen. â€¢ Bonded Fiber Matrix and Mechanically Bonded Fiber Matrix: â€¢ On steep slopes use Bonded Fiber Matrix (BFM) or Mechanically Bonded Fiber Matrix (MBFM) products. Apply BFM/MBFM products at a minimum rate of 3,000 pounds per acre of mulch with approximately 10 percent tackifier. Achieve a minimum of 95 percent soil coverage during application. Numerous products are available commercially. Installed products per manufacturerâ€™s instructions.

FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 Generally, products come in 40-50 pound bags and include all necessary ingredients except for seed and fertilizer. â€¢ BFMs and MBFMs provide good alternatives to blankets in most areas requiring vegetation establishment. Advantages over blankets include: â€¢ BFM and MBFMs do not require surface preparation. â€¢ Helicopters can assist in installing BFM and MBFMs in remote areas. â€¢ On slopes steeper than 2.5H:1V, blanket installers may require ropes and harnesses for safety. â€¢ Installing BFM and MBFMs can save at least $1,000 per acre compared to blankets. Maintenance Reseed any seeded areas that fail to establish at least 80 percent cover Standards (100 percent cover for areas that receive sheet or concentrated flows). If reseeding is ineffective, use an alternate method such as sodding, mulching, or nets/blankets. If winter weather prevents adequate grass growth, this time limit may be relaxed at the discretion of the local authority when sensitive areas would otherwise be protected. â€¢ Reseed and protect by mulch any areas that experience erosion after achieving adequate cover. Reseed and protect by mulch any eroded area. â€¢ Supply seeded areas with adequate moisture, but do not water to the extent that it causes runoff.

FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C121: Mulching Purpose Mulching soils provides immediate temporary protection from erosion. Mulch also enhances plant establishment by conserving moisture, holding fertilizer, seed, and topsoil in place, and moderating soil temperatures. There is an enormous variety of mulches that can be used. This section discusses only the most common types of mulch. Conditions of Use As a temporary cover measure, mulch should be used: â€¢ For less than 30 days on disturbed areas that require cover. â€¢ At all times for seeded areas, especially during the wet season and during the hot summer months. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ During the wet season on slopes steeper than 3H:1V with more than 10 feet of vertical relief. Mulch may be applied at any time of the year and must be refreshed periodically. â€¢ For seeded areas mulch may be made up of 100 percent: cottonseed meal; fibers made of wood, recycled cellulose, hemp, kenaf; compost; or blends of these. Tackifier shall be plant-based, such as guar or alpha plantago, or chemical-based such as polyacrylamide or polymers. Any mulch or tackifier product used shall be installed per manufacturerâ€™s instructions. Generally, mulches come in 40-50 pound bags. Seed and fertilizer are added at time of application. Design and For mulch materials, application rates, and specifications, see Table 4.1.8. Installation Always use a 2-inch minimum mulch thickness; increase the thickness Specifications until the ground is 95% covered (i.e. not visible under the mulch layer). Note: Thickness may be increased for disturbed areas in or near sensitive areas or other areas highly susceptible to erosion. Where the option of â€œCompostâ€ is selected, it should be a coarse compost that meets the following size gradations when tested in accordance with the U.S. Composting Council â€œTest Methods for the Examination of Compost and Compostingâ€ (TMECC) Test Method 02.02-B. Coarse Compost Minimum Percent passing 3â€ sieve openings 100% Minimum Percent passing 1â€ sieve openings 90% Minimum Percent passing Â¾â€ sieve openings 70% Minimum Percent passing Â¼â€ sieve openings 40% Mulch used within the ordinary high-water mark of surface waters should be selected to minimize potential flotation of organic matter. Composted organic materials have higher specific gravities (densities) than straw, wood, or chipped material. Consult Hydraulic Permit Authority (HPA) for mulch mixes if applicable. Maintenance â€¢ The thickness of the cover must be maintained. Standards â€¢ Any areas that experience erosion shall be remulched and/or protected with a net or blanket. If the erosion problem is drainage related, then the problem shall be fixed and the eroded area remulched.

The thickness of straw may be reduced by half acre when used in conjunction with seeding. In windy areas straw must be held in place by crimping, using a tackifier, or covering with netting. Blown straw always has to be held in place with a tackifier as even light winds will blow it away. Straw, however, has several deficiencies that should be considered when selecting mulch materials. It often introduces and/or encourages the propagation of weed species and it has no significant long- term benefits.

(WSDOT specification (9-14.4(4)) FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C122: Nets and Blankets Purpose Erosion control nets and blankets are intended to prevent erosion and hold seed and mulch in place on steep slopes and in channels so that vegetation can become well established. In addition, some nets and blankets can be used to permanently reinforce turf to protect drainage ways during high flows. Nets (commonly called matting) are strands of material woven into an open, but high-tensile strength net (for example, coconut fiber matting). Blankets are strands of material that are not tightly woven, but instead form a layer of interlocking fibers, typically held together by a biodegradable or photodegradable netting (for example, excelsior or straw blankets). They generally have lower tensile strength than nets, but cover the ground more completely. Coir (coconut fiber) fabric comes as both nets and blankets. Conditions of Use Erosion control nets and blankets should be used: â€¢ To aid permanent vegetated stabilization of slopes 2H:1V or greater and with more than 10 feet of vertical relief. â€¢ For drainage ditches and swales (highly recommended). The application of appropriate netting or blanket to drainage ditches and swales can protect bare soil from channelized runoff while vegetation is established. Nets and blankets also can capture a great deal of sediment due to their open, porous structure. Nets and blankets can be used to permanently stabilize channels and may provide a cost- effective, environmentally preferable alternative to riprap. 100 percent synthetic blankets manufactured for use in ditches may be easily reused as temporary ditch liners. Disadvantages of blankets include: â€¢ Surface preparation required. â€¢ On slopes steeper than 2.5H:1V, blanket installers may need to be roped and harnessed for safety. â€¢ They cost at least $4,000-6,000 per acre installed. Advantages of blankets include: â€¢ Installation without mobilizing special equipment. â€¢ Installation by anyone with minimal training â€¢ Installation in stages or phases as the project progresses. â€¢ Installers can hand place seed and fertilizer as they progress down the slope. â€¢ Installation in any weather. â€¢ There are numerous types of blankets that can be designed with various parameters in mind. Those parameters include: fiber blend, mesh strength, longevity, biodegradability, cost, and availability. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 Design and â€¢ See Figure 4.1.3 and Figure 4.1.4 for typical orientation and Installation installation of blankets used in channels and as slope protection. Note: Specifications these are typical only; all blankets must be installed per manufacturerâ€™s installation instructions. â€¢ Installation is critical to the effectiveness of these products. If good ground contact is not achieved, runoff can concentrate under the product, resulting in significant erosion. â€¢ Installation of Blankets on Slopes: 1. Complete final grade and track walk up and down the slope. 2. Install hydromulch with seed and fertilizer. 3. Dig a small trench, approximately 12 inches wide by 6 inches deep along the top of the slope. 4. Install the leading edge of the blanket into the small trench and staple approximately every 18 inches. NOTE: Staples are metal, â€œUâ€-shaped, and a minimum of 6 inches long. Longer staples are used in sandy soils. Biodegradable stakes are also available. 5. Roll the blanket slowly down the slope as installer walks backwards. NOTE: The blanket rests against the installerâ€™s legs. Staples are installed as the blanket is unrolled. It is critical that the proper staple pattern is used for the blanket being installed. The blanket is not to be allowed to roll down the slope on its own as this stretches the blanket making it impossible to maintain soil contact. In addition, no one is allowed to walk on the blanket after it is in place. 6. If the blanket is not long enough to cover the entire slope length, the trailing edge of the upper blanket should overlap the leading edge of the lower blanket and be stapled. On steeper slopes, this overlap should be installed in a small trench, stapled, and covered with soil. â€¢ With the variety of products available, it is impossible to cover all the details of appropriate use and installation. Therefore, it is critical that the design engineer consult the manufacturer's information and that a site visit takes place in order to ensure that the product specified is appropriate. Information is also available at the following web sites: 1. WSDOT (Section 3.2.4): http://www.wsdot.wa.gov/NR/rdonlyres/3B41E087-FA86-4717- 932D-D7A8556CCD57/0/ErosionTrainingManual.pdf 2. Texas Transportation Institute: http://www.txdot.gov/business/doing_business/product_evaluation/ erosion_control.htm FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Use jute matting in conjunction with mulch (BMP C121). Excelsior, woven straw blankets and coir (coconut fiber) blankets may be installed without mulch. There are many other types of erosion control nets and blankets on the market that may be appropriate in certain circumstances. â€¢ In general, most nets (e.g., jute matting) require mulch in order to prevent erosion because they have a fairly open structure. Blankets typically do not require mulch because they usually provide complete protection of the surface. â€¢ Extremely steep, unstable, wet, or rocky slopes are often appropriate candidates for use of synthetic blankets, as are riverbanks, beaches and other high-energy environments. If synthetic blankets are used, the soil should be hydromulched first. â€¢ 100-percent biodegradable blankets are available for use in sensitive areas. These organic blankets are usually held together with a paper or fiber mesh and stitching which may last up to a year. â€¢ Most netting used with blankets is photodegradable, meaning they break down under sunlight (not UV stabilized). However, this process can take months or years even under bright sun. Once vegetation is established, sunlight does not reach the mesh. It is not uncommon to find non-degraded netting still in place several years after installation. This can be a problem if maintenance requires the use of mowers or ditch cleaning equipment. In addition, birds and small animals can become trapped in the netting. Maintenance â€¢ Maintain good contact with the ground. Erosion must not occur Standards beneath the net or blanket. â€¢ Repair and staple any areas of the net or blanket that are damaged or not in close contact with the ground. â€¢ Fix and protect eroded areas if erosion occurs due to poorly controlled drainage.

Figure 4.1.4 â€“ Slope Installation FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C123: Plastic Covering Purpose Plastic covering provides immediate, short-term erosion protection to slopes and disturbed areas. Conditions of Plastic covering may be used on disturbed areas that require cover Use measures for less than 30 days, except as stated below. â€¢ Plastic is particularly useful for protecting cut and fill slopes and stockpiles. Note: The relatively rapid breakdown of most polyethylene sheeting makes it unsuitable for long-term (greater than six months) applications. â€¢ Due to rapid runoff caused by plastic covering, do not use this method upslope of areas that might be adversely impacted by concentrated runoff. Such areas include steep and/or unstable slopes. â€¢ Plastic sheeting may result in increased runoff volumes and velocities, requiring additional on-site measures to counteract the increases. Creating a trough with wattles or other material can convey clean water away from these areas. â€¢ To prevent undercutting, trench and backfill rolled plastic covering products. â€¢ While plastic is inexpensive to purchase, the added cost of installation, maintenance, removal, and disposal make this an expensive material, up to $1.50-2.00 per square yard. â€¢ Whenever plastic is used to protect slopes install water collection measures at the base of the slope. These measures include plastic- covered berms, channels, and pipes used to covey clean rainwater away from bare soil and disturbed areas. Do not mix clean runoff from a plastic covered slope with dirty runoff from a project. â€¢ Other uses for plastic include: 1. Temporary ditch liner. 2. Pond liner in temporary sediment pond. 3. Liner for bermed temporary fuel storage area if plastic is not reactive to the type of fuel being stored. 4. Emergency slope protection during heavy rains. 5. Temporary drainpipe (â€œelephant trunkâ€) used to direct water. Design and â€¢ Plastic slope cover must be installed as follows: Installation 1. Run plastic up and down slope, not across slope. Specifications 2. Plastic may be installed perpendicular to a slope if the slope length is less than 10 feet. 3. Minimum of 8-inch overlap at seams. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 4. On long or wide slopes, or slopes subject to wind, tape all seams. 5. Place plastic into a small (12-inch wide by 6-inch deep) slot trench at the top of the slope and backfill with soil to keep water from flowing underneath. 6. Place sand filled burlap or geotextile bags every 3 to 6 feet along seams and tie them together with twine to hold them in place. 7. Inspect plastic for rips, tears, and open seams regularly and repair immediately. This prevents high velocity runoff from contacting bare soil which causes extreme erosion. 8. Sandbags may be lowered into place tied to ropes. However, all sandbags must be staked in place. â€¢ Plastic sheeting shall have a minimum thickness of 0.06 millimeters. â€¢ If erosion at the toe of a slope is likely, a gravel berm, riprap, or other suitable protection shall be installed at the toe of the slope in order to reduce the velocity of runoff. Maintenance â€¢ Torn sheets must be replaced and open seams repaired. Standards â€¢ Completely remove and replace the plastic if it begins to deteriorate due to ultraviolet radiation. â€¢ Completely remove plastic when no longer needed. â€¢ Dispose of old tires used to weight down plastic sheeting appropriately.

The products are available for review on Ecologyâ€™s website at http://www.ecy.wa.gov/programs/wq/stormwater/newtech/equivalent.html FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C124: Sodding Purpose The purpose of sodding is to establish permanent turf for immediate erosion protection and to stabilize drainage ways where concentrated overland flow will occur. Conditions of Use Sodding may be used in the following areas: â€¢ Disturbed areas that require short-term or long-term cover. â€¢ Disturbed areas that require immediate vegetative cover. â€¢ All waterways that require vegetative lining. Waterways may also be seeded rather than sodded, and protected with a net or blanket. Design and Sod shall be free of weeds, of uniform thickness (approximately 1-inch Installation thick), and shall have a dense root mat for mechanical strength. Specifications The following steps are recommended for sod installation: â€¢ Shape and smooth the surface to final grade in accordance with the approved grading plan. The swale needs to be overexcavated 4 to 6 inches below design elevation to allow room for placing soil amendment and sod. â€¢ Amend 4 inches (minimum) of compost into the top 8 inches of the soil if the organic content of the soil is less than ten percent or the permeability is less than 0.6 inches per hour. See http://www.ecy.wa.gov/programs/swfa/organics/soil.html for further information. â€¢ Fertilize according to the supplier's recommendations. â€¢ Work lime and fertilizer 1 to 2 inches into the soil, and smooth the surface. â€¢ Lay strips of sod beginning at the lowest area to be sodded and perpendicular to the direction of water flow. Wedge strips securely into place. Square the ends of each strip to provide for a close, tight fit. Stagger joints at least 12 inches. Staple on slopes steeper than 3H:1V. Staple the upstream edge of each sod strip. â€¢ Roll the sodded area and irrigate. â€¢ When sodding is carried out in alternating strips or other patterns, seed the areas between the sod immediately after sodding. Maintenance If the grass is unhealthy, the cause shall be determined and appropriate Standards action taken to reestablish a healthy groundcover. If it is impossible to establish a healthy groundcover due to frequent saturation, instability, or some other cause, the sod shall be removed, the area seeded with an appropriate mix, and protected with a net or blanket. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C125: Topsoiling / Composting Purpose Topsoiling and composting provide a suitable growth medium for final site stabilization with vegetation. While not a permanent cover practice in itself, topsoiling and composting are an integral component of providing permanent cover in those areas where there is an unsuitable soil surface for plant growth. Use this BMP in conjunction with other BMPs such as seeding, mulching, or sodding. Note that this BMP is functionally the same as BMP T5.13 (see Chapter 5 of Volume V of this manual) which is required for all disturbed areas that will be developed as lawn or landscaped areas at the completed project site. Native soils and disturbed soils that have been organically amended not only retain much more stormwater, but they also serve as effective biofilters for urban pollutants and, by supporting more vigorous plant growth, reduce the water, fertilizer and pesticides needed to support installed landscapes. Topsoil does not include any subsoils but only the material from the top several inches including organic debris. Conditions of â€¢ Permanent landscaped areas shall contain healthy topsoil that reduces Use the need for fertilizers, improves overall topsoil quality, provides for better vegetal health and vitality, improves hydrologic characteristics, and reduces the need for irrigation. â€¢ Leave native soils and the duff layer undisturbed to the maximum extent practicable. Stripping of existing, properly functioning soil system and vegetation for the purpose of topsoiling during construction is not acceptable. Preserve existing soil systems in undisturbed and uncompacted conditions if functioning properly. â€¢ Areas that already have good topsoil, such as undisturbed areas, do not require soil amendments. â€¢ Restore, to the maximum extent practical, native soils disturbed during clearing and grading to a condition equal to or better than the original site conditionâ€™s moisture-holding capacity. Use on-site native topsoil, incorporate amendments into on-site soil, or import blended topsoil to meet this requirement. â€¢ Topsoiling is a required procedure when establishing vegetation on shallow soils, and soils of critically low pH (high acid) levels. â€¢ Beware of where the topsoil comes from, and what vegetation was on site before disturbance, invasive plant seeds may be included and could cause problems for establishing native plants, landscaped areas, or grasses. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Topsoil from the site will contain mycorrhizal bacteria that are necessary for healthy root growth and nutrient transfer. These native mycorrhiza are acclimated to the site and will provide optimum conditions for establishing grasses. Use commercially available mycorrhiza products when using off-site topsoil. Design and Meet the following requirements for disturbed areas that will be Installation developed as lawn or landscaped areas at the completed project site: Specifications â€¢ Maximize the depth of the topsoil wherever possible to provide the maximum possible infiltration capacity and beneficial growth medium. Topsoil shall have: â€¢ A minimum depth of 8-inches. Scarify subsoils below the topsoil layer at least 4-inches with some incorporation of the upper material to avoid stratified layers, where feasible. Ripping or re- structuring the subgrade may also provide additional benefits regarding the overall infiltration and interflow dynamics of the soil system. â€¢ A minimum organic content of 10% dry weight in planting beds, and 5% organic matter content in turf areas. Incorporate organic amendments to a minimum 8-inch depth except where tree roots or other natural features limit the depth of incorporation. â€¢ A pH between 6.0 and 8.0 or matching the pH of the undisturbed soil. â€¢ If blended topsoil is imported, then fines should be limited to 25 percent passing through a 200 sieve. â€¢ Mulch planting beds with 2 inches of organic material â€¢ Accomplish the required organic content, depth, and pH by returning native topsoil to the site, importing topsoil of sufficient organic content, and/or incorporating organic amendments.When using the option of incorporating amendments to meet the organic content requirement, use compost that meets the compost specification for Bioretention (See BMP T7.30 in Chapter 7 of Volume V of this manual), with the exception that the compost may have up to 35% biosolids or manure. â€¢ Sections three through seven of the document entitled, Guidelines and Resources for Implementing Soil Quality and Depth BMP T5.13 in WDOE Stormwater Management Manual for Western Washington, provides useful guidance for implementing whichever option is chosen. It includes guidance for pre-approved default strategies and guidance for custom strategies. Check with your local jurisdiction concerning its acceptance of this guidance. It is available through the organization, Soils for Salmon. As of this printing the document may be found at: http://www.soilsforsalmon.org/pdf/Soil_BMP_Manual.pdf. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ The final composition and construction of the soil system will result in a natural selection or favoring of certain plant species over time. For example, incorporation of topsoil may favor grasses, while layering with mildly acidic, high-carbon amendments may favor more woody vegetation. â€¢ Allow sufficient time in scheduling for topsoil spreading prior to seeding, sodding, or planting. â€¢ Take care when applying top soil to subsoils with contrasting textures. Sandy topsoil over clayey subsoil is a particularly poor combination, as water creeps along the junction between the soil layers and causes the topsoil to slough. If topsoil and subsoil are not properly bonded, water will not infiltrate the soil profile evenly and it will be difficult to establish vegetation. The best method to prevent a lack of bonding is to actually work the topsoil into the layer below for a depth of at least 6 inches. â€¢ Field exploration of the site shall be made to determine if there is surface soil of sufficient quantity and quality to justify stripping. Topsoil shall be friable and loamy (loam, sandy loam, silt loam, sandy clay loam, and clay loam). Avoid areas of natural ground water recharge. â€¢ Stripping shall be confined to the immediate construction area. A 4- inch to 6-inch stripping depth is common, but depth may vary depending on the particular soil. All surface runoff control structures shall be in place prior to stripping. â€¢ Do not place topsoil while in a frozen or muddy condition, when the subgrade is excessively wet, or when conditions exist that may otherwise be detrimental to proper grading or proposed sodding or seeding. â€¢ In any areas requiring grading remove and stockpile the duff layer and topsoil on site in a designated, controlled area, not adjacent to public resources and critical areas. Stockpiled topsoil is to be reapplied to other portions of the site where feasible. â€¢ Locate the topsoil stockpile so that it meets specifications and does not interfere with work on the site. It may be possible to locate more than one pile in proximity to areas where topsoil will be used. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 Stockpiling of topsoil shall occur in the following manner: â€¢ Side slopes of the stockpile shall not exceed 2H:1V. â€¢ Between October 1 and April 30: â€¢ An interceptor dike with gravel outlet and silt fence shall surround all topsoil. â€¢ Within 2 days complete erosion control seeding, or covering stockpiles with clear plastic, or other mulching materials. â€¢ Between May 1 and September 30: â€¢ An interceptor dike with gravel outlet and silt fence shall surround all topsoil if the stockpile will remain in place for a longer period of time than active construction grading. â€¢ Within 7 days complete erosion control seeding, or covering stockpiles with clear plastic, or other mulching materials. â€¢ When native topsoil is to be stockpiled and reused the following should apply to ensure that the mycorrhizal bacterial, earthworms, and other beneficial organisms will not be destroyed: 1. Re-install topsoil within 4 to 6 weeks. 2. Do not allow the saturation of topsoil with water. 3. Do not use plastic covering. Maintenance â€¢ Inspect stockpiles regularly, especially after large storm events. Standards Stabilize any areas that have eroded. â€¢ Establish soil quality and depth toward the end of construction and once established, protect from compaction, such as from large machinery use, and from erosion. â€¢ Plant and mulch soil after installation. â€¢ Leave plant debris or its equivalent on the soil surface to replenish organic matter. â€¢ Reduce and adjust, where possible, the use of irrigation, fertilizers, herbicides and pesticides, rather than continuing to implement formerly established practices. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C140: Dust Control Purpose Dust control prevents wind transport of dust from disturbed soil surfaces onto roadways, drainage ways, and surface waters. Conditions of Use â€¢ In areas (including roadways) subject to surface and air movement of dust where on-site and off-site impacts to roadways, drainage ways, or surface waters are likely. Design and â€¢ Vegetate or mulch areas that will not receive vehicle traffic. In areas Installation where planting, mulching, or paving is impractical, apply gravel or Specifications landscaping rock. â€¢ Limit dust generation by clearing only those areas where immediate activity will take place, leaving the remaining area(s) in the original condition. Maintain the original ground cover as long as practical. â€¢ Construct natural or artificial windbreaks or windscreens. These may be designed as enclosures for small dust sources. â€¢ Sprinkle the site with water until surface is wet. Repeat as needed. To prevent carryout of mud onto street, refer to Stabilized Construction Entrance (BMP C105). â€¢ Irrigation water can be used for dust control. Irrigation systems should be installed as a first step on sites where dust control is a concern. â€¢ Spray exposed soil areas with a dust palliative, following the manufacturerâ€™s instructions and cautions regarding handling and application. Used oil is prohibited from use as a dust suppressant. Local governments may approve other dust palliatives such as calcium chloride or PAM. â€¢ PAM (BMP C126) added to water at a rate of 0.5 lbs. per 1,000 gallons of water per acre and applied from a water truck is more effective than water alone. This is due to increased infiltration of water into the soil and reduced evaporation. In addition, small soil particles are bonded together and are not as easily transported by wind. Adding PAM may actually reduce the quantity of water needed for dust control. Use of PAM could be a cost-effective dust control method. Techniques that can be used for unpaved roads and lots include: â€¢ Lower speed limits. High vehicle speed increases the amount of dust stirred up from unpaved roads and lots. â€¢ Upgrade the road surface strength by improving particle size, shape, and mineral types that make up the surface and base materials. â€¢ Add surface gravel to reduce the source of dust emission. Limit the amount of fine particles (those smaller than .075 mm) to 10 to 20 percent. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Use geotextile fabrics to increase the strength of new roads or roads undergoing reconstruction. â€¢ Encourage the use of alternate, paved routes, if available. â€¢ Restrict use of paved roadways by tracked vehicles and heavy trucks to prevent damage to road surface and base. â€¢ Apply chemical dust suppressants using the admix method, blending the product with the top few inches of surface material. Suppressants may also be applied as surface treatments. â€¢ Pave unpaved permanent roads and other trafficked areas. â€¢ Use vacuum street sweepers. â€¢ Remove mud and other dirt promptly so it does not dry and then turn into dust. â€¢ Limit dust-causing work on windy days. â€¢ Contact your local Air Pollution Control Authority for guidance and training on other dust control measures. Compliance with the local Air Pollution Control Authority constitutes compliance with this BMP. Maintenance Respray area as necessary to keep dust to a minimum. Standards FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C151: Concrete Handling Purpose Concrete work can generate process water and slurry that contain fine particles and high pH, both of which can violate water quality standards in the receiving water. Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use this BMP to minimize and eliminate concrete, concrete process water, and concrete slurry from entering waters of the state. Conditions of Use Any time concrete is used, utilize these management practices. Concrete construction projects include, but are not limited to, the following: â€¢ Curbs â€¢ Sidewalks â€¢ Roads â€¢ Bridges â€¢ Foundations â€¢ Floors â€¢ Runways Design and â€¢ Assure that washout of concrete trucks, chutes, pumps, and internals is Installation performed at an approved off-site location or in designated concrete Specifications washout areas. Do not wash out concrete trucks onto the ground, or into storm drains, open ditches, streets, or streams. Refer to BMP C154 for information on concrete washout areas. â€¢ Return unused concrete remaining in the truck and pump to the originating batch plant for recycling.

Maintenance Check containers for holes in the liner daily during concrete pours and Standards repair the same day. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C152: Sawcutting and Surfacing Pollution Prevention Purpose Sawcutting and surfacing operations generate slurry and process water that contains fine particles and high pH (concrete cutting), both of which can violate the water quality standards in the receiving water. Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use this BMP to minimize and eliminate process water and slurry created through sawcutting or surfacing from entering waters of the State. Conditions of Use Utilize these management practices anytime sawcutting or surfacing operations take place. Sawcutting and surfacing operations include, but are not limited to, the following: â€¢ Sawing â€¢ Coring â€¢ Grinding â€¢ Roughening â€¢ Hydro-demolition â€¢ Bridge and road surfacing Design and â€¢ Vacuum slurry and cuttings during cutting and surfacing operations. Installation â€¢ Slurry and cuttings shall not remain on permanent concrete or asphalt Specifications pavement overnight. â€¢ Slurry and cuttings shall not drain to any natural or constructed drainage conveyance including stormwater systems. This may require temporarily blocking catch basins. â€¢ Dispose of collected slurry and cuttings in a manner that does not violate ground water or surface water quality standards. â€¢ Do not allow process water generated during hydro-demolition, surface roughening or similar operations to drain to any natural or constructed drainage conveyance including stormwater systems. Dispose process water in a manner that does not violate ground water or surface water quality standards. â€¢ Handle and dispose cleaning waste material and demolition debris in a manner that does not cause contamination of water. Dispose of sweeping material from a pick-up sweeper at an appropriate disposal site. Maintenance Continually monitor operations to determine whether slurry, cuttings, or Standards process water could enter waters of the state. If inspections show that a violation of water quality standards could occur, stop operations and immediately implement preventive measures such as berms, barriers, secondary containment, and vacuum trucks. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C160: Certified Erosion and Sediment Control Lead Purpose The project proponent designates at least one person as the responsible representative in charge of erosion and sediment control (ESC), and water quality protection. The designated person shall be the Certified Erosion and Sediment Control Lead (CESCL) who is responsible for ensuring compliance with all local, state, and federal erosion and sediment control and water quality requirements. Conditions of Use A CESCL shall be made available on projects one acre or larger that discharge stormwater to surface waters of the state. Sites less than one acre may have a person without CESCL certification conduct inspections; sampling is not required on sites that disturb less than an acre. â€¢ The CESCL shall: â€¢ Have a current certificate proving attendance in an erosion and sediment control training course that meets the minimum ESC training and certification requirements established by Ecology (see details below). Ecology will maintain a list of ESC training and certification providers at: http://www.ecy.wa.gov/programs/wq/stormwater/cescl.html OR â€¢ Be a Certified Professional in Erosion and Sediment Control (CPESC); for additional information go to: www.cpesc.net Specifications â€¢ Certification shall remain valid for three years. â€¢ The CESCL shall have authority to act on behalf of the contractor or developer and shall be available, or on-call, 24 hours per day throughout the period of construction. â€¢ The Construction SWPPP shall include the name, telephone number, fax number, and address of the designated CESCL. â€¢ A CESCL may provide inspection and compliance services for multiple construction projects in the same geographic region.

FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C200: Interceptor Dike and Swale Purpose Provide a ridge of compacted soil, or a ridge with an upslope swale, at the top or base of a disturbed slope or along the perimeter of a disturbed construction area to convey stormwater. Use the dike and/or swale to intercept the runoff from unprotected areas and direct it to areas where erosion can be controlled. This can prevent storm runoff from entering the work area or sediment-laden runoff from leaving the construction site. Conditions of Use Where the runoff from an exposed site or disturbed slope must be conveyed to an erosion control facility which can safely convey the stormwater. â€¢ Locate upslope of a construction site to prevent runoff from entering disturbed area. â€¢ When placed horizontally across a disturbed slope, it reduces the amount and velocity of runoff flowing down the slope. â€¢ Locate downslope to collect runoff from a disturbed area and direct water to a sediment basin. Design and â€¢ Dike and/or swale and channel must be stabilized with temporary or Installation permanent vegetation or other channel protection during construction. Specifications â€¢ Channel requires a positive grade for drainage; steeper grades require channel protection and check dams. â€¢ Review construction for areas where overtopping may occur. â€¢ Can be used at top of new fill before vegetation is established. â€¢ May be used as a permanent diversion channel to carry the runoff. â€¢ Sub-basin tributary area should be one acre or less. â€¢ Design capacity for the peak volumetric flow rate calculated using a 10-minute time step from a 10-year, 24-hour storm, assuming a Type 1A rainfall distribution, for temporary facilities. Alternatively, use 1.6 times the 10-year, 1-hour flow indicated by an approved continuous runoff model. For facilities that will also serve on a permanent basis, consult the local governmentâ€™s drainage requirements. Interceptor dikes shall meet the following criteria: Top Width 2 feet minimum. Height 1.5 feet minimum on berm. Side Slope 2H:1V or flatter. Grade Depends on topography, however, dike system minimum is 0.5%, and maximum is 1%. Compaction Minimum of 90 percent ASTM D698 standard proctor. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 Horizontal Spacing of Interceptor Dikes: Average Slope Slope Percent Flowpath Length 20H:1V or less 3-5% 300 feet (10 to 20)H:1V 5-10% 200 feet (4 to 10)H:1V 10-25% 100 feet (2 to 4)H:1V 25-50% 50 feet Stabilization depends on velocity and reach Slopes <5% Seed and mulch applied within 5 days of dike construction (see BMP C121, Mulching). Slopes 5 - 40% Dependent on runoff velocities and dike materials. Stabilization should be done immediately using either sod or riprap or other measures to avoid erosion. â€¢ The upslope side of the dike shall provide positive drainage to the dike outlet. No erosion shall occur at the outlet. Provide energy dissipation measures as necessary. Sediment-laden runoff must be released through a sediment trapping facility. â€¢ Minimize construction traffic over temporary dikes. Use temporary cross culverts for channel crossing. Interceptor swales shall meet the following criteria: Bottom Width 2 feet minimum; the cross-section bottom shall be level. Depth 1-foot minimum. Side Slope 2H:1V or flatter. Grade Maximum 5 percent, with positive drainage to a suitable outlet (such as a sediment pond). Stabilization Seed as per BMP C120, Temporary and Permanent Seeding, or BMP C202, Channel Lining, 12 inches thick riprap pressed into the bank and extending at least 8 inches vertical from the bottom. â€¢ Inspect diversion dikes and interceptor swales once a week and after every rainfall. Immediately remove sediment from the flow area. â€¢ Damage caused by construction traffic or other activity must be repaired before the end of each working day. Check outlets and make timely repairs as needed to avoid gully formation. When the area below the temporary diversion dike is permanently stabilized, remove the dike and fill and stabilize the channel to blend with the natural surface. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C207: Check Dams Purpose Construction of small dams across a swale or ditch reduces the velocity of concentrated flow and dissipates energy at the check dam. Conditions of Use Where temporary channels or permanent channels are not yet vegetated, channel lining is infeasible, and/or velocity checks are required. â€¢ Check dams may not be placed in streams unless approved by the State Department of Fish and Wildlife. Check dams may not be placed in wetlands without approval from a permitting agency. â€¢ Do not place check dams below the expected backwater from any salmonid bearing water between October 1 and May 31 to ensure that there is no loss of high flow refuge habitat for overwintering juvenile salmonids and emergent salmonid fry. â€¢ Construct rock check dams from appropriately sized rock. The rock used must be large enough to stay in place given the expected design flow through the channel. The rock must be placed by hand or by mechanical means (no dumping of rock to form dam) to achieve complete coverage of the ditch or swale and to ensure that the center of the dam is lower than the edges. â€¢ Check dams may also be constructed of either rock or pea-gravel filled bags. Numerous new products are also available for this purpose. They tend to be re-usable, quick and easy to install, effective, and cost efficient. â€¢ Place check dams perpendicular to the flow of water. â€¢ The dam should form a triangle when viewed from the side. This prevents undercutting as water flows over the face of the dam rather than falling directly onto the ditch bottom. â€¢ Before installing check dams impound and bypass upstream water flow away from the work area. Options for bypassing include pumps, siphons, or temporary channels. â€¢ Check dams in association with sumps work more effectively at slowing flow and retaining sediment than just a check dam alone. A deep sump should be provided immediately upstream of the check dam. â€¢ In some cases, if carefully located and designed, check dams can remain as permanent installations with very minor regrading. They may be left as either spillways, in which case accumulated sediment would be graded and seeded, or as check dams to prevent further sediment from leaving the site. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ The maximum spacing between the dams shall be such that the toe of the upstream dam is at the same elevation as the top of the downstream dam. â€¢ Keep the maximum height at 2 feet at the center of the dam. â€¢ Keep the center of the check dam at least 12 inches lower than the outer edges at natural ground elevation. â€¢ Keep the side slopes of the check dam at 2H:1V or flatter. â€¢ Key the stone into the ditch banks and extend it beyond the abutments a minimum of 18 inches to avoid washouts from overflow around the dam. â€¢ Use filter fabric foundation under a rock or sand bag check dam. If a blanket ditch liner is used, filter fabric is not necessary. A piece of organic or synthetic blanket cut to fit will also work for this purpose. â€¢ In the case of grass-lined ditches and swales, all check dams and accumulated sediment shall be removed when the grass has matured sufficiently to protect the ditch or swale - unless the slope of the swale is greater than 4 percent. The area beneath the check dams shall be seeded and mulched immediately after dam removal. â€¢ Ensure that channel appurtenances, such as culvert entrances below check dams, are not subject to damage or blockage from displaced stones. Figure 4.2.7 depicts a typical rock check dam. Maintenance Check dams shall be monitored for performance and sediment Standards accumulation during and after each runoff producing rainfall. Sediment shall be removed when it reaches one half the sump depth. â€¢ Anticipate submergence and deposition above the check dam and erosion from high flows around the edges of the dam. â€¢ If significant erosion occurs between dams, install a protective riprap liner in that portion of the channel.

Conditions of Use Use storm drain inlet protection at inlets that are operational before permanent stabilization of the disturbed drainage area. Provide protection for all storm drain inlets downslope and within 500 feet of a disturbed or construction area, unless conveying runoff entering catch basins to a sediment pond or trap. Also consider inlet protection for lawn and yard drains on new home construction. These small and numerous drains coupled with lack of gutters in new home construction can add significant amounts of sediment into the roof drain system. If possible delay installing lawn and yard drains until just before landscaping or cap these drains to prevent sediment from entering the system until completion of landscaping. Provide 18-inches of sod around each finished lawn and yard drain. Table 4.2.2 lists several options for inlet protection. All of the methods for storm drain inlet protection tend to plug and require a high frequency of maintenance. Limit drainage areas to one acre or less. Possibly provide emergency overflows with additional end-of-pipe treatment where stormwater ponding would cause a hazard.

(less than 5%) 2. Excavate a basin of sufficient size adjacent to the drop inlet. 3. The top of the structure (ponding height) must be well below the ground elevation downslope to prevent runoff from bypassing the inlet. A temporary dike may be necessary on the downslope side of the structure. Figure 4.2.8 â€“ Block and Gravel Filter Gravel and Wire Mesh Filter - A gravel barrier placed over the top of the inlet. This structure does not provide an overflow. â€¢ Use a hardware cloth or comparable wire mesh with Â½-inch openings. â€¢ Use coarse aggregate. â€¢ Provide a height 1-foot or more, 18-inches wider than inlet on all sides. â€¢ Place wire mesh over the drop inlet so that the wire extends a minimum of 1-foot beyond each side of the inlet structure. â€¢ Overlap the strips if more than one strip of mesh is necessary. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Place coarse aggregate over the wire mesh. â€¢ Provide at least a 12-inch depth of gravel over the entire inlet opening and extend at least 18-inches on all sides. Catchbasin Filters â€“ Use inserts designed by manufacturers for construction sites. The limited sediment storage capacity increases the amount of inspection and maintenance required, which may be daily for heavy sediment loads. To reduce maintenance requirements combine a catchbasin filter with another type of inlet protection. This type of inlet protection provides flow bypass without overflow and therefore may be a better method for inlets located along active rights-of-way. â€¢ Provides 5 cubic feet of storage. â€¢ Requires dewatering provisions. â€¢ Provides a high-flow bypass that will not clog under normal use at a construction site. â€¢ Insert the catchbasin filter in the catchbasin just below the grating. Curb Inlet Protection with Wooden Weir â€“ Barrier formed around a curb inlet with a wooden frame and gravel. â€¢ Use wire mesh with Â½-inch openings. â€¢ Use extra strength filter cloth. â€¢ Construct a frame. â€¢ Attach the wire and filter fabric to the frame. â€¢ Pile coarse washed aggregate against wire/fabric. â€¢ Place weight on frame anchors. Block and Gravel Curb Inlet Protection â€“ Barrier formed around a curb inlet with concrete blocks and gravel. See Figure 4.2.9. â€¢ Use wire mesh with Â½-inch openings. â€¢ Place two concrete blocks on their sides abutting the curb at either side of the inlet opening. These are spacer blocks. â€¢ Place a 2x4 stud through the outer holes of each spacer block to align the front blocks. â€¢ Place blocks on their sides across the front of the inlet and abutting the spacer blocks. â€¢ Place wire mesh over the outside vertical face. â€¢ Pile coarse aggregate against the wire to the top of the barrier. Curb and Gutter Sediment Barrier â€“ Sandbag or rock berm (riprap and aggregate) 3 feet high and 3 feet wide in a horseshoe shape. See Figure 4.2.10. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Construct a horseshoe shaped berm, faced with coarse aggregate if using riprap, 3 feet high and 3 feet wide, at least 2 feet from the inlet. â€¢ Construct a horseshoe shaped sedimentation trap on the outside of the berm sized to sediment trap standards for protecting a culvert inlet. Maintenance â€¢ Inspect catch basin filters frequently, especially after storm events. Standards Clean and replace clogged inserts. For systems with clogged stone filters: pull away the stones from the inlet and clean or replace. An alternative approach would be to use the clogged stone as fill and put fresh stone around the inlet. â€¢ Do not wash sediment into storm drains while cleaning.

The contractor shall install and maintain temporary silt fences at the locations shown in the Plans. 2. Construct silt fences in areas of clearing, grading, or drainage prior to starting those activities. 3. The silt fence shall have a 2-feet min. and a 2Â½-feet max. height above the original ground surface. 4. The filter fabric shall be sewn together at the point of manufacture to form filter fabric lengths as required. Locate all sewn seams at support posts. Alternatively, two sections of silt fence can be overlapped, provided the Contractor can demonstrate, to the satisfaction of the Engineer, that the overlap is long enough and that the adjacent fence sections are close enough together to prevent silt laden water from escaping through the fence at the overlap. 5. Attach the filter fabric on the up-slope side of the posts and secure with staples, wire, or in accordance with the manufacturer's recommendations. Attach the filter fabric to the posts in a manner that reduces the potential for tearing. 6. Support the filter fabric with wire or plastic mesh, dependent on the properties of the geotextile selected for use. If wire or plastic mesh is used, fasten the mesh securely to the up-slope side of the posts with the filter fabric up-slope of the mesh. 7. Mesh support, if used, shall consist of steel wire with a maximum mesh spacing of 2-inches, or a prefabricated polymeric mesh. The strength of the wire or polymeric mesh shall be equivalent to or greater than 180 lbs. grab tensile strength. The polymeric mesh must be as resistant to the same level of ultraviolet radiation as the filter fabric it supports. 8. Bury the bottom of the filter fabric 4-inches min. below the ground surface. Backfill and tamp soil in place over the buried portion of the filter fabric, so that no flow can pass beneath the fence and scouring cannot occur. When wire or polymeric back-up support FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 mesh is used, the wire or polymeric mesh shall extend into the ground 3-inches min. 9. Drive or place the fence posts into the ground 18-inches min. A 12â€“inch min. depth is allowed if topsoil or other soft subgrade soil is not present and 18-inches cannot be reached. Increase fence post min. depths by 6 inches if the fence is located on slopes of 3H:1V or steeper and the slope is perpendicular to the fence. If required post depths cannot be obtained, the posts shall be adequately secured by bracing or guying to prevent overturning of the fence due to sediment loading. 10. Use wood, steel or equivalent posts. The spacing of the support posts shall be a maximum of 6-feet. Posts shall consist of either: â€¢ Wood with dimensions of 2-inches by 2-inches wide min. and a 3-feet min. length. Wood posts shall be free of defects such as knots, splits, or gouges. â€¢ No. 6 steel rebar or larger. â€¢ ASTM A 120 steel pipe with a minimum diameter of 1-inch. â€¢ U, T, L, or C shape steel posts with a minimum weight of 1.35 lbs./ft. â€¢ Other steel posts having equivalent strength and bending resistance to the post sizes listed above. 11.Locate silt fences on contour as much as possible, except at the ends of the fence, where the fence shall be turned uphill such that the silt fence captures the runoff water and prevents water from flowing around the end of the fence. 12. If the fence must cross contours, with the exception of the ends of the fence, place gravel check dams perpendicular to the back of the fence to minimize concentrated flow and erosion. The slope of the fence line where contours must be crossed shall not be steeper than 3H:1V. â€¢ Gravel check dams shall be approximately 1-foot deep at the back of the fence. Gravel check dams shall be continued perpendicular to the fence at the same elevation until the top of the check dam intercepts the ground surface behind the fence. â€¢ Gravel check dams shall consist of crushed surfacing base course, gravel backfill for walls, or shoulder ballast. Gravel check dams shall be located every 10 feet along the fence where the fence must cross contours. â€¢ Refer to Figure 4.2.13 for slicing method details. Silt fence installation using the slicing method specifications: FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 1. The base of both end posts must be at least 2- to 4-inches above the top of the filter fabric on the middle posts for ditch checks to drain properly. Use a hand level or string level, if necessary, to mark base points before installation. 2. Install posts 3- to 4-feet apart in critical retention areas and 6- to 7- feet apart in standard applications. 3. Install posts 24-inches deep on the downstream side of the silt fence, and as close as possible to the filter fabric, enabling posts to support the filter fabric from upstream water pressure. 4. Install posts with the nipples facing away from the filter fabric. 5. Attach the filter fabric to each post with three ties, all spaced within the top 8-inches of the filter fabric. Attach each tie diagonally 45 degrees through the filter fabric, with each puncture at least 1-inch vertically apart. Each tie should be positioned to hang on a post nipple when tightening to prevent sagging. 6. Wrap approximately 6-inches of fabric around the end posts and secure with 3 ties. 7. No more than 24-inches of a 36-inch filter fabric is allowed above ground level. Compact the soil immediately next to the filter fabric with the front wheel of the tractor, skid steer, or roller exerting at least 60 pounds per square inch. Compact the upstream side first and then each side twice for a total of four trips. Check and correct the silt fence installation for any deviation before compaction. Use a flat-bladed shovel to tuck fabric deeper into the ground if necessary.

Standards â€¢ Intercept and convey all evident concentrated flows uphill of the silt fence to a sediment pond. â€¢ Check the uphill side of the fence for signs of the fence clogging and acting as a barrier to flow and then causing channelization of flows parallel to the fence. If this occurs, replace the fence or remove the trapped sediment. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Remove sediment deposits when the deposit reaches approximately one-third the height of the silt fence, or install a second silt fence. â€¢ Replace filter fabric that has deteriorated due to ultraviolet breakdown. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 BMP C240: Sediment Trap Purpose A sediment trap is a small temporary ponding area with a gravel outlet used to collect and store sediment from sites cleared and/or graded during construction. Sediment traps, along with other perimeter controls, shall be installed before any land disturbance takes place in the drainage area. Conditions of Use Prior to leaving a construction site, stormwater runoff must pass through a sediment pond or trap or other appropriate sediment removal best management practice. Non-engineered sediment traps may be used on-site prior to an engineered sediment trap or sediment pond to provide additional sediment removal capacity. It is intended for use on sites where the tributary drainage area is less than 3 acres, with no unusual drainage features, and a projected build-out time of six months or less. The sediment trap is a temporary measure (with a design life of approximately 6 months) and shall be maintained until the site area is permanently protected against erosion by vegetation and/or structures. Sediment traps and ponds are only effective in removing sediment down to about the medium silt size fraction. Runoff with sediment of finer grades (fine silt and clay) will pass through untreated, emphasizing the need to control erosion to the maximum extent first. Whenever possible, sediment-laden water shall be discharged into on-site, relatively level, vegetated areas (see BMP C234 â€“ Vegetated Strip). This is the only way to effectively remove fine particles from runoff unless chemical treatment or filtration is used. This can be particularly useful after initial treatment in a sediment trap or pond. The areas of release must be evaluated on a site-by-site basis in order to determine appropriate locations for and methods of releasing runoff. Vegetated wetlands shall not be used for this purpose. Frequently, it may be possible to pump water from the collection point at the downhill end of the site to an upslope vegetated area. Pumping shall only augment the treatment system, not replace it, because of the possibility of pump failure or runoff volume in excess of pump capacity. All projects that are constructing permanent facilities for runoff quantity control should use the rough-graded or final-graded permanent facilities for traps and ponds. This includes combined facilities and infiltration facilities. When permanent facilities are used as temporary sedimentation facilities, the surface area requirement of a sediment trap or pond must be met. If the surface area requirements are larger than the surface area of the permanent facility, then the trap or pond shall be enlarged to comply with the surface area requirement. The permanent pond shall also be divided into two cells as required for sediment ponds. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 Either a permanent control structure or the temporary control structure (described in BMP C241, Temporary Sediment Pond) can be used. If a permanent control structure is used, it may be advisable to partially restrict the lower orifice with gravel to increase residence time while still allowing dewatering of the pond. A shut-off valve may be added to the control structure to allow complete retention of stormwater in emergency situations. In this case, an emergency overflow weir must be added. A skimmer may be used for the sediment trap outlet if approved by the Local Permitting Authority. Design and â€¢ See Figures 4.2.16 and 4.2.17 for details. Installation â€¢ If permanent runoff control facilities are part of the project, they Specifications should be used for sediment retention. â€¢ To determine the sediment trap geometry, first calculate the design surface area (SA) of the trap, measured at the invert of the weir. Use the following equation: SA = FS(Q2/Vs) where Q2 = Design inflow based on the peak discharge from the developed 2-year runoff event from the contributing drainage area as computed in the hydrologic analysis. The 10-year peak flow shall be used if the project size, expected timing and duration of construction, or downstream conditions warrant a higher level of protection. If no hydrologic analysis is required, the Rational Method may be used. Vs = The settling velocity of the soil particle of interest. The 0.02 mm (medium silt) particle with an assumed density of 2.65 g/cm3 has been selected as the particle of interest and has a settling velocity (Vs) of 0.00096 ft/sec. FS = A safety factor of 2 to account for non-ideal settling. Therefore, the equation for computing surface area becomes: SA = 2 x Q2/0.00096 or 2080 square feet per cfs of inflow Note: Even if permanent facilities are used, they must still have a surface area that is at least as large as that derived from the above formula. If they do not, the pond must be enlarged. â€¢ To aid in determining sediment depth, all sediment traps shall have a staff gauge with a prominent mark 1-foot above the bottom of the trap. FROM: Volume II - Construction Stormwater Pollution Prevention - December 2014 â€¢ Sediment traps may not be feasible on utility projects due to the limited work space or the short-term nature of the work. Portable tanks may be used in place of sediment traps for utility projects. Maintenance â€¢ Sediment shall be removed from the trap when it reaches 1-foot in Standards depth. â€¢ Any damage to the pond embankments or slopes shall be repaired.

Clearing, grading and/or excavation that results in the disturbance of one or more acres (including off-site disturbance acreage authorized in S1.C.2) and discharges stormwater to surface waters of the State; and clearing, grading and/or excavation on sites smaller than one acre that are part of a larger common plan of development or sale, if the common plan of development or sale will ultimately disturb one acre or more and discharge stormwater to surface waters of the State. i. This includes forest practices (including, but not limited to, class IV conversions) that are part of a construction activity that will result in the disturbance of one or more acres, and discharge to surface waters of the State (that is, forest practices that prepare a site for construction activities); and b. Any size construction activity discharging stormwater to waters of the State that the Washington State Department of Ecology (Ecology): i. Determines to be a significant contributor of pollutants to waters of the State of Washington. ii. Reasonably expects to cause a violation of any water quality standard. 2. Operators of the following activities are not required to seek coverage under this CSWGP (unless specifically required under Special Condition S1.B.1.b. above): a. Construction activities that discharge all stormwater and non-stormwater to ground water, sanitary sewer, or combined sewer, and have no point source discharge to either surface water or a storm sewer system that drains to surface waters of the State. b. Construction activities covered under an Erosivity Waiver (Special Condition S2.C). c. Routine maintenance that is performed to maintain the original line and grade, hydraulic capacity, or original purpose of a facility. Construction Stormwater General Permit Page 5 C. Authorized Discharges: 1. Stormwater Associated with Construction Activity. Subject to compliance with the terms and conditions of this permit, Permittees are authorized to discharge stormwater associated with construction activity to surface waters of the State or to a storm sewer system that drains to surface waters of the State. (Note that â€œsurface waters of the Stateâ€ may exist on a construction site as well as off site; for example, a creek running through a site.) 2. Stormwater Associated with Construction Support Activity. This permit also authorizes stormwater discharge from support activities related to the permitted construction site (for example, an on-site portable rock crusher, off-site equipment staging yards, material storage areas, borrow areas, etc.) provided: a. The support activity relates directly to the permitted construction site that is required to have an NPDES permit; and b. The support activity is not a commercial operation serving multiple unrelated construction projects, and does not operate beyond the completion of the construction activity; and c. Appropriate controls and measures are identified in the Stormwater Pollution Prevention Plan (SWPPP) for the discharges from the support activity areas. 3. Non-Stormwater Discharges. The categories and sources of non-stormwater discharges identified below are authorized conditionally, provided the discharge is consistent with the terms and conditions of this permit: a.

Ecology reviews public comments and considers whether discharges from this project would cause a measurable change in receiving water quality, and, if so, whether the project is necessary and in the overriding public interest according to Tier II antidegradation requirements under WAC 173-201A-320. Comments can be submitted to: Department of Ecology, PO Box 47696, Olympia, Washington 98504-7696 Attn: Water Quality Program, Construction Stormwater.â€ Construction Stormwater General Permit Page 10 C. Erosivity Waiver Construction site operators may qualify for an erosivity waiver from the CSWGP if the following conditions are met: 1. The site will result in the disturbance of fewer than 5 acres and the site is not a portion of a common plan of development or sale that will disturb 5 acres or greater. 2. Calculation of Erosivity â€œRâ€ Factor and Regional Timeframe: a. The projectâ€™s rainfall erosivity factor (â€œRâ€ Factor) must be less than 5 during the period of construction activity, as calculated (see the CSWGP homepage http://www.ecy.wa.gov/programs/wq/stormwater/construction/index.html for a link to the EPAâ€™s calculator and step by step instructions on computing the â€œRâ€ Factor in the EPA Erosivity Waiver Fact Sheet). The period of construction activity starts when the land is first disturbed and ends with final stabilization. In addition: b. The entire period of construction activity must fall within the following timeframes: i. For sites west of the Cascades Crest: June 15 â€“ September 15. ii. For sites east of the Cascades Crest, excluding the Central Basin: June 15 â€“ October 15. iii. For sites east of the Cascades Crest, within the Central Basin: no additional timeframe restrictions apply. The Central Basin is defined as the portions of Eastern Washington with mean annual precipitation of less than 12 inches. For a map of the Central Basin (Average Annual Precipitation Region 2), refer to http://www.ecy.wa.gov/programs/wq/stormwater/ construction/resourcesguidance.html. 3. Construction site operators must submit a complete Erosivity Waiver certification form at least one week before disturbing the land. Certification must include statements that the operator will: a. Comply with applicable local stormwater requirements; and b. Implement appropriate erosion and sediment control BMPs to prevent violations of water quality standards. 4. This waiver is not available for facilities declared significant contributors of pollutants as defined in Special Condition S1.B.1.b. or for any size construction activity that could reasonably expect to cause a violation of any water quality standard as defined in Special Condition S1.B.1.b.ii. 5. This waiver does not apply to construction activities which include non- stormwater discharges listed in Special Condition S1.C.3. Construction Stormwater General Permit Page 11 6. If construction activity extends beyond the certified waiver period for any reason, the operator must either: a. Recalculate the rainfall erosivity â€œRâ€ factor using the original start date and a new projected ending date and, if the â€œRâ€ factor is still under 5 and the entire project falls within the applicable regional timeframe in Special Condition S2.C.2.b, complete and submit an amended waiver certification form before the original waiver expires; or b. Submit a complete permit application to Ecology in accordance with Special Condition S2.A and B before the end of the certified waiver period. S3. COMPLIANCE WITH STANDARDS A. Discharges must not cause or contribute to a violation of surface water quality standards (Chapter 173-201A WAC), ground water quality standards (Chapter 173-200 WAC), sediment management standards (Chapter 173-204 WAC), and human health-based criteria in the National Toxics Rule (40 CFR Part 131.36). Discharges not in compliance with these standards are not authorized. B. Prior to the discharge of stormwater and non-stormwater to waters of the State, the Permittee must apply all known, available, and reasonable methods of prevention, control, and treatment (AKART). This includes the preparation and implementation of an adequate SWPPP, with all appropriate BMPs installed and maintained in accordance with the SWPPP and the terms and conditions of this permit. C. Ecology presumes that a Permittee complies with water quality standards unless discharge monitoring data or other site-specific information demonstrates that a discharge causes or contributes to a violation of water quality standards, when the Permittee complies with the following conditions. The Permittee must fully: 1. Comply with all permit conditions, including planning, sampling, monitoring, reporting, and recordkeeping conditions. 2. Implement stormwater BMPs contained in stormwater management manuals published or approved by Ecology, or BMPs that are demonstrably equivalent to BMPs contained in stormwater technical manuals published or approved by Ecology, including the proper selection, implementation, and maintenance of all applicable and appropriate BMPs for on-site pollution control. (For purposes of this section, the stormwater manuals listed in Appendix 10 of the Phase I Municipal Stormwater Permit are approved by Ecology.) D. Where construction sites also discharge to ground water, the ground water discharges must also meet the terms and conditions of this CSWGP. Permittees who discharge to ground water through an injection well must also comply with any applicable requirements of the Underground Injection Control (UIC) regulations, Chapter 173-218 WAC. Construction Stormwater General Permit Page 12 S4. MONITORING REQUIREMENTS, BENCHMARKS AND REPORTING TRIGGERS A. Site Log Book The Permittee must maintain a site log book that contains a record of the implementation of the SWPPP and other permit requirements, including the installation and maintenance of BMPs, site inspections, and stormwater monitoring. B. Site Inspections The Permitteeâ€™s site inspections must include all areas disturbed by construction activities, all BMPs, and all stormwater discharge points under the Permitteeâ€™s operational control. (See Special Conditions S4.B.3 and B.4 below for detailed requirements of the Permitteeâ€™s Certified Erosion and Sediment Control Lead [CESCL].) Construction sites one acre or larger that discharge stormwater to surface waters of the State must have site inspections conducted by a certified CESCL. Sites less than one acre may have a person without CESCL certification conduct inspections. 1. The Permittee must examine stormwater visually for the presence of suspended sediment, turbidity, discoloration, and oil sheen. The Permittee must evaluate the effectiveness of BMPs and determine if it is necessary to install, maintain, or repair BMPs to improve the quality of stormwater discharges. Based on the results of the inspection, the Permittee must correct the problems identified by: a. Reviewing the SWPPP for compliance with Special Condition S9 and making appropriate revisions within 7 days of the inspection. b. Immediately beginning the process of fully implementing and maintaining appropriate source control and/or treatment BMPs as soon as possible, addressing the problems no later than within 10 days of the inspection. If installation of necessary treatment BMPs is not feasible within 10 days, Ecology may approve additional time when an extension is requested by a Permittee within the initial 10-day response period. c. Documenting BMP implementation and maintenance in the site log book. 2. The Permittee must inspect all areas disturbed by construction activities, all BMPs, and all stormwater discharge points at least once every calendar week and within 24 hours of any discharge from the site. (For purposes of this condition, individual discharge events that last more than one day do not require daily inspections. For example, if a stormwater pond discharges continuously over the course of a week, only one inspection is required that week.) The Permittee may reduce the inspection frequency for temporarily stabilized, inactive sites to once every calendar month. Construction Stormwater General Permit Page 13 3. The Permittee must have staff knowledgeable in the principles and practices of erosion and sediment control. The CESCL (sites one acre or more) or inspector (sites less than one acre) must have the skills to assess the: a. Site conditions and construction activities that could impact the quality of stormwater, and b. Effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. 4. The SWPPP must identify the CESCL or inspector, who must be present on site or on-call at all times. The CESCL must obtain this certification through an approved erosion and sediment control training program that meets the minimum training standards established by Ecology (see BMP C160 in the manual referred to in Special Condition S9.C.1 and 2). 5. The Permittee must summarize the results of each inspection in an inspection report or checklist and enter the report/checklist into, or attach it to, the site log book. At a minimum, each inspection report or checklist must include: a. Inspection date and time. b. Weather information, the general conditions during inspection and the approximate amount of precipitation since the last inspection, and precipitation within the last 24 hours. c. A summary or list of all implemented BMPs, including observations of all erosion/sediment control structures or practices. d. A description of the locations: i. Of BMPs inspected; ii. Of BMPs that need maintenance and why; iii. Of BMPs that failed to operate as designed or intended; and iv. Where additional or different BMPs are needed, and why. e. A description of stormwater discharged from the site. The Permittee must note the presence of suspended sediment, turbidity, discoloration, and oil sheen, as applicable. f. Any water quality monitoring performed during inspection. g. General comments and notes, including a brief description of any BMP repairs, maintenance or installations made following the inspection. h. A summary report and a schedule of implementation of the remedial actions that the Permittee plans to take if the site inspection indicates that the site is out of compliance. The remedial actions taken must meet the requirements of the SWPPP and the permit. Construction Stormwater General Permit Page 14 i. The name, title, and signature of the person conducting the site inspection, a phone number or other reliable method to reach this person, and the following statement: â€œI certify that this report is true, accurate, and complete to the best of my knowledge and belief.â€ Table 3: Summary of Primary Monitoring Requirements Size of Soil Weekly Site Weekly Weekly Weekly pH CESCL Disturbance1 Inspections Sampling w/ Sampling w/ Sampling2 Required for Turbidity Transparency Inspections?

Construction activity means clearing, grading, excavation, and any other activity that disturbs the surface of the land, including ingress/egress from the site. 2 If construction activity results in the disturbance of 1 acre or more, and involves significant concrete work (1,000 cubic yards of poured concrete or recycled concrete over the life of a project) or the use of engineered soils (soil amendments including but not limited to Portland cement-treated base [CTB], cement kiln dust [CKD], or fly ash), and stormwater from the affected area drains to surface waters of the State or to a storm sewer stormwater collection system that drains to other surface waters of the State, the Permittee must conduct pH sampling in accordance with Special Condition S4.D. 3 Sites with one or more acres, but fewer than 5 acres of soil disturbance, must conduct turbidity or transparency sampling in accordance with Special Condition S4.C. 4 Sites equal to or greater than 5 acres of soil disturbance must conduct turbidity sampling using a turbidity meter in accordance with Special Condition S4.C. Construction Stormwater General Permit Page 15 C. Turbidity/Transparency Sampling Requirements 1. Sampling Methods a. If construction activity involves the disturbance of 5 acres or more, the Permittee must conduct turbidity sampling per Special Condition S4.C. b. If construction activity involves 1 acre or more but fewer than 5 acres of soil disturbance, the Permittee must conduct either transparency sampling or turbidity sampling per Special Condition S4.C. 2. Sampling Frequency a. The Permittee must sample all discharge points at least once every calendar week when stormwater (or authorized non-stormwater) discharges from the site or enters any on-site surface waters of the state (for example, a creek running through a site); sampling is not required on sites that disturb less than an acre. b. Samples must be representative of the flow and characteristics of the discharge. c. Sampling is not required when there is no discharge during a calendar week. d. Sampling is not required outside of normal working hours or during unsafe conditions. e. If the Permittee is unable to sample during a monitoring period, the Permittee must include a brief explanation in the monthly Discharge Monitoring Report (DMR). f. Sampling is not required before construction activity begins. g. The Permittee may reduce the sampling frequency for temporarily stabilized, inactive sites to once every calendar month. 3. Sampling Locations a. Sampling is required at all points where stormwater associated with construction activity (or authorized non-stormwater) is discharged off site, including where it enters any on-site surface waters of the state (for example, a creek running through a site). b. The Permittee may discontinue sampling at discharge points that drain areas of the project that are fully stabilized to prevent erosion. c. The Permittee must identify all sampling point(s) on the SWPPP site map and clearly mark these points in the field with a flag, tape, stake or other visible marker. d. Sampling is not required for discharge that is sent directly to sanitary or combined sewer systems. Construction Stormwater General Permit Page 16 e. The Permittee may discontinue sampling at discharge points in areas of the project where the Permittee no longer has operational control of the construction activity. 4. Sampling and Analysis Methods a. The Permittee performs turbidity analysis with a calibrated turbidity meter (turbidimeter) either on site or at an accredited lab. The Permittee must record the results in the site log book in nephelometric turbidity units (NTUs). b. The Permittee performs transparency analysis on site with a 1Â¾-inch-diameter, 60-centimeter (cm)-long transparency tube. The Permittee will record the results in the site log book in centimeters (cm).

Turbidity/Transparency Benchmark Values and Reporting Triggers The benchmark value for turbidity is 25 NTUs or less. The benchmark value for transparency is 33 centimeters (cm). Note: Benchmark values do not apply to discharges to segments of water bodies on Washington Stateâ€™s 303(d) list (Category 5) for turbidity, fine sediment, or phosphorus; these discharges are subject to a numeric effluent limit for turbidity. Refer to Special Condition S8 for more information. a. Turbidity 26 â€“ 249 NTUs, or Transparency 32 â€“ 7 cm: If the discharge turbidity is 26 to 249 NTUs; or if discharge transparency is less than 33 cm, but equal to or greater than 6 cm, the Permittee must: i. Review the SWPPP for compliance with Special Condition S9 and make appropriate revisions within 7 days of the date the discharge exceeded the benchmark. ii. Immediately begin the process to fully implement and maintain appropriate source control and/or treatment BMPs as soon as possible, addressing the problems within 10 days of the date the discharge exceeded the benchmark. If installation of necessary treatment BMPs is not feasible within 10 days, Ecology may approve additional time when the Permittee requests an extension within the initial 10-day response period. Construction Stormwater General Permit Page 17 iii. Document BMP implementation and maintenance in the site log book. b. Turbidity 250 NTUs or greater, or Transparency 6 cm or less: If a discharge pointâ€™s turbidity is 250 NTUs or greater, or if discharge transparency is less than or equal to 6 cm, the Permittee must complete the reporting and adaptive management process described below. i.

Document BMP implementation and maintenance in the site log book. v. Sample discharges daily until: a) Turbidity is 25 NTUs (or lower); or b) Transparency is 33 cm (or greater); or Construction Stormwater General Permit Page 18 c) The Permittee has demonstrated compliance with the water quality limit for turbidity: 1) No more than 5 NTUs over background turbidity, if background is less than 50 NTUs, or 2) No more than 10% over background turbidity, if background is 50 NTUs or greater; or d) The discharge stops or is eliminated. D. pH Sampling Requirements â€“ Significant Concrete Work or Engineered Soils If construction activity results in the disturbance of 1 acre or more, and involves significant concrete work (significant concrete work means greater than 1000 cubic yards poured concrete or recycled concrete used over the life of a project) or the use of engineered soils (soil amendments including but not limited to Portland cement-treated base [CTB], cement kiln dust [CKD], or fly ash), and stormwater from the affected area drains to surface waters of the State or to a storm sewer system that drains to surface waters of the State, the Permittee must conduct pH sampling as set forth below. Note: In addition, discharges to segments of water bodies on Washington Stateâ€™s 303(d) list (Category 5) for high pH are subject to a numeric effluent limit for pH; refer to Special Condition S8. 1. For sites with significant concrete work, the Permittee must begin the pH sampling period when the concrete is first poured and exposed to precipitation, and continue weekly throughout and after the concrete pour and curing period, until stormwater pH is in the range of 6.5 to 8.5 (su). 2. For sites with recycled concrete where monitoring is required, the Permittee must begin the weekly pH sampling period when the recycled concrete is first exposed to precipitation and must continue until the recycled concrete is fully stabilized with the stormwater pH in the range of 6.5 to 8.5 (su). 3. For sites with engineered soils, the Permittee must begin the pH sampling period when the soil amendments are first exposed to precipitation and must continue until the area of engineered soils is fully stabilized. 4. During the applicable pH monitoring period defined above, the Permittee must obtain a representative sample of stormwater and conduct pH analysis at least once per week. 5. The Permittee must sample pH in the sediment trap/pond(s) or other locations that receive stormwater runoff from the area of significant concrete work or engineered soils before the stormwater discharges to surface waters. 6. The benchmark value for pH is 8.5 standard units. Anytime sampling indicates that pH is 8.5 or greater, the Permittee must either: Construction Stormwater General Permit Page 19 a. Prevent the high pH water (8.5 or above) from entering storm sewer systems or surface waters; or b. If necessary, adjust or neutralize the high pH water until it is in the range of pH 6.5 to 8.5 (su) using an appropriate treatment BMP such as carbon dioxide (CO2) sparging or dry ice. The Permittee must obtain written approval from Ecology before using any form of chemical treatment other than CO2 sparging or dry ice. 7. The Permittee must perform pH analysis on site with a calibrated pH meter, pH test kit, or wide range pH indicator paper. The Permittee must record pH sampling results in the site log book. S5. REPORTING AND RECORDKEEPING REQUIREMENTS A. High Turbidity Reporting Anytime sampling performed in accordance with Special Condition S4.C indicates turbidity has reached the 250 NTUs or more (or transparency less than or equal to 6 cm) high turbidity reporting level, the Permittee must either call the applicable Ecology Regionâ€™s Environmental Report Tracking System (ERTS) number by phone within 24 hours of analysis or submit an electronic ERTS report (or submit an electronic report through Ecologyâ€™s Water Quality Permitting Portal (WQWebPortal) â€“ Permit Submittals when the form is available). See the CSWGP web site for links to ERTS and the WQWebPortal: http://www.ecy.wa.gov/programs/wq/stormwater/construction/ index.html. Also, see phone numbers in Special Condition S4.C.5.b.i. B. Discharge Monitoring Reports (DMRs) Permittees required to conduct water quality sampling in accordance with Special Conditions S4.C (Turbidity/Transparency), S4.D (pH), S8 (303[d]/TMDL sampling), and/or G13 (Additional Sampling) must submit the results to Ecology. Permittees must submit monitoring data using Ecology's WQWebDMR web application accessed through Ecologyâ€™s Water Quality Permitting Portal. To find out more information and to sign up for WQWebDMR go to: http://www.ecy.wa.gov/programs/ wq/permits/paris/portal.html. Permittees unable to submit electronically (for example, those who do not have an internet connection) must contact Ecology to request a waiver and obtain instructions on how to obtain a paper copy DMR at: Department of Ecology Water Quality Program - Construction Stormwater PO Box 47696 Olympia, Washington 98504-7696 Permittees who obtain a waiver not to use WQWebDMR must use the forms provided to them by Ecology; submittals must be mailed to the address above. Permittees shall Construction Stormwater General Permit Page 20 submit DMR forms to be received by Ecology within 15 days following the end of each month. If there was no discharge during a given monitoring period, all Permittees must submit a DMR as required with â€œno discharge" entered in place of the monitoring results. DMRs are required for the full duration of permit coverage (from issuance date to termination). For more information, contact Ecology staff using information provided at the following web site: www.ecy.wa.gov/programs/wq/permits/paris/contacts.html. C. Records Retention The Permittee must retain records of all monitoring information (site log book, sampling results, inspection reports/checklists, etc.), Stormwater Pollution Prevention Plan, copy of the permit coverage letter (including Transfer of Coverage documentation), and any other documentation of compliance with permit requirements for the entire life of the construction project and for a minimum of three years following the termination of permit coverage. Such information must include all calibration and maintenance records, and records of all data used to complete the application for this permit. This period of retention must be extended during the course of any unresolved litigation regarding the discharge of pollutants by the Permittee or when requested by Ecology. D. Recording Results For each measurement or sample taken, the Permittee must record the following information: 1. Date, place, method, and time of sampling or measurement. 2. The first and last name of the individual who performed the sampling or measurement. 3. The date(s) the analyses were performed. 4. The first and last name of the individual who performed the analyses. 5. The analytical techniques or methods used. 6. The results of all analyses. E. Additional Monitoring by the Permittee If the Permittee monitors any pollutant more frequently than required by this permit using test procedures specified by Special Condition S4 of this permit, the results of this monitoring must be included in the calculation and reporting of the data submitted in the Permitteeâ€™s DMR. F. Noncompliance Notification In the event the Permittee is unable to comply with any part of the terms and conditions of this permit, and the resulting noncompliance may cause a threat to human health or the environment (such as but not limited to spills of fuels or other materials, catastrophic pond or slope failure, and discharges that violate water quality standards), or exceed Construction Stormwater General Permit Page 21 numeric effluent limitations (see S8. Discharges to 303(d) or TMDL Waterbodies), the Permittee must, upon becoming aware of the circumstance: 1. Notify Ecology within 24-hours of the failure to comply by calling the applicable Regional office ERTS phone number (refer to Special Condition S4.C.5.b.i. or www.ecy.wa.gov/programs/wq/stormwater/construction/turbidity.html for Regional ERTS phone numbers). 2. Immediately take action to prevent the discharge/pollution, or otherwise stop or correct the noncompliance, and, if applicable, repeat sampling and analysis of any noncompliance immediately and submit the results to Ecology within five (5) days of becoming aware of the violation. 3. Submit a detailed written report to Ecology within five (5) days, of the time the Permittee becomes aware of the circumstances, unless requested earlier by Ecology. The report must be submitted using Ecologyâ€™s Water Quality Permitting Portal (WQWebPortal) - Permit Submittals, unless a waiver from electronic reporting has been granted according to S5.B. The report must contain a description of the noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and the steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance. The Permittee must report any unanticipated bypass and/or upset that exceeds any effluent limit in the permit in accordance with the 24-hour reporting requirement contained in 40 C.F.R. 122.41(l)(6). Compliance with these requirements does not relieve the Permittee from responsibility to maintain continuous compliance with the terms and conditions of this permit or the resulting liability for failure to comply. Upon request of the Permittee, Ecology may waive the requirement for a written report on a case-by- case basis, if the immediate notification is received by Ecology within 24 hours. G. Access to Plans and Records 1. The Permittee must retain the following permit documentation (plans and records) on site, or within reasonable access to the site, for use by the operator or for on-site review by Ecology or the local jurisdiction: a. General Permit b. Permit Coverage Letter c. Stormwater Pollution Prevention Plan (SWPPP) d. Site Log Book 2. The Permittee must address written requests for plans and records listed above (Special Condition S5.G.1) as follows: Construction Stormwater General Permit Page 22 a. The Permittee must provide a copy of plans and records to Ecology within 14 days of receipt of a written request from Ecology. b. The Permittee must provide a copy of plans and records to the public when requested in writing. Upon receiving a written request from the public for the Permitteeâ€™s plans and records, the Permittee must either: i. Provide a copy of the plans and records to the requester within 14 days of a receipt of the written request; or ii. Notify the requester within 10 days of receipt of the written request of the location and times within normal business hours when the plans and records may be viewed; and provide access to the plans and records within 14 days of receipt of the written request; or iii. Within 14 days of receipt of the written request, the Permittee may submit a copy of the plans and records to Ecology for viewing and/or copying by the requester at an Ecology office, or a mutually agreed location. If plans and records are viewed and/or copied at a location other than at an Ecology office, the Permittee will provide reasonable access to copying services for which a reasonable fee may be charged. The Permittee must notify the requester within 10 days of receipt of the request where the plans and records may be viewed and/or copied. S6. PERMIT FEES The Permittee must pay permit fees assessed by Ecology. Fees for stormwater discharges covered under this permit are established by Chapter 173-224 WAC. Ecology continues to assess permit fees until the permit is terminated in accordance with Special Condition S10 or revoked in accordance with General Condition G5. S7. SOLID AND LIQUID WASTE DISPOSAL The Permittee must handle and dispose of solid and liquid wastes generated by construction activity, such as demolition debris, construction materials, contaminated materials, and waste materials from maintenance activities, including liquids and solids from cleaning catch basins and other stormwater facilities, in accordance with: A. Special Condition S3, Compliance with Standards B. WAC 173-216-110 C. Other applicable regulations S8. DISCHARGES TO 303(d) OR TMDL WATERBODIES A. Sampling and Numeric Effluent Limits For Certain Discharges to 303(d)-listed Waterbodies Construction Stormwater General Permit Page 23 1. Permittees who discharge to segments of waterbodies listed as impaired by the State of Washington under Section 303(d) of the Clean Water Act for turbidity, fine sediment, high pH, or phosphorus, must conduct water quality sampling according to the requirements of this section, and Special Conditions S4.C.2.b-f and S4.C.3.b-d, and must comply with the applicable numeric effluent limitations in S8.C and S8.D. 2. All references and requirements associated with Section 303(d) of the Clean Water Act mean the most current listing by Ecology of impaired waters (Category 5) that exists on January 1, 2016, or the date when the operatorâ€™s complete permit application is received by Ecology, whichever is later. B. Limits on Coverage for New Discharges to TMDL or 303(d)-listed Waters Operators of construction sites that discharge to a TMDL or 303(d)-listed waterbody are not eligible for coverage under this permit unless the operator: 1. Prevents exposing stormwater to pollutants for which the waterbody is impaired, and retains documentation in the SWPPP that details procedures taken to prevent exposure on site; or 2. Documents that the pollutants for which the waterbody is impaired are not present at the site, and retains documentation of this finding within the SWPPP; or 3. Provides Ecology with data indicating the discharge is not expected to cause or contribute to an exceedance of a water quality standard, and retains such data on site with the SWPPP. The operator must provide data and other technical information to Ecology that sufficiently demonstrate: a. For discharges to waters without an EPA-approved or -established TMDL, that the discharge of the pollutant for which the water is impaired will meet in- stream water quality criteria at the point of discharge to the waterbody; or b. For discharges to waters with an EPA-approved or -established TMDL, that there is sufficient remaining wasteload allocation in the TMDL to allow construction stormwater discharge and that existing dischargers to the waterbody are subject to compliance schedules designed to bring the waterbody into attainment with water quality standards. Operators of construction sites are eligible for coverage under this permit if Ecology issues permit coverage based upon an affirmative determination that the discharge will not cause or contribute to the existing impairment. C. Sampling and Numeric Effluent Limits for Discharges to Water Bodies on the 303(d) List for Turbidity, Fine Sediment, or Phosphorus 1. Permittees who discharge to segments of water bodies on the 303(d) list (Category 5) for turbidity, fine sediment, or phosphorus must conduct turbidity sampling in accordance with Special Condition S4.C.2 and comply with either of the numeric effluent limits noted in Table 5 below. Construction Stormwater General Permit Page 24 2. As an alternative to the 25 NTUs effluent limit noted in Table 5 below (applied at the point where stormwater [or authorized non-stormwater] is discharged off-site), Permittees may choose to comply with the surface water quality standard for turbidity. The standard is: no more than 5 NTUs over background turbidity when the background turbidity is 50 NTUs or less, or no more than a 10% increase in turbidity when the background turbidity is more than 50 NTUs. In order to use the water quality standard requirement, the sampling must take place at the following locations: a. Background turbidity in the 303(d)-listed receiving water immediately upstream (upgradient) or outside the area of influence of the discharge. b. Turbidity at the point of discharge into the 303(d)-listed receiving water, inside the area of influence of the discharge. 3. Discharges that exceed the numeric effluent limit for turbidity constitute a violation of this permit. 4. Permittees whose discharges exceed the numeric effluent limit shall sample discharges daily until the violation is corrected and comply with the non- compliance notification requirements in Special Condition S5.F. Table 5: Turbidity, Fine Sediment & Phosphorus Sampling and Limits for 303(d)-Listed Waters Parameter identified Parameter Unit Analytical Sampling Numeric Effluent in 303(d) listing Sampled Method Frequency Limit1 ï‚· Turbidity Turbidity NTU SM2130 Weekly, if 25 NTUs, at the ï‚· Fine Sediment discharging point where ï‚· Phosphorus stormwater is discharged from the site; OR In compliance with the surface water quality standard for turbidity (S8.C.2.a) 1Permittees subject to a numeric effluent limit for turbidity may, at their discretion, choose either numeric effluent limitation based on site-specific considerations including, but not limited to, safety, access and convenience. D. Discharges to Water Bodies on the 303(d) List for High pH 1. Permittees who discharge to segments of water bodies on the 303(d) list (Category 5) for high pH must conduct pH sampling in accordance with the table below, and comply with the numeric effluent limit of pH 6.5 to 8.5 su (Table 6). Construction Stormwater General Permit Page 25 Table 6: pH Sampling and Limits for 303(d)-Listed Waters Parameter identified in Parameter Analytical Sampling Numeric Effluent 303(d) listing Sampled/Units Method Frequency Limit High pH pH /Standard pH meter Weekly, if In the range of 6.5 Units discharging â€“ 8.5 2. At the Permitteeâ€™s discretion, compliance with the limit shall be assessed at one of the following locations: a. Directly in the 303(d)-listed waterbody segment, inside the immediate area of influence of the discharge; or b. Alternatively, the Permittee may measure pH at the point where the discharge leaves the construction site, rather than in the receiving water. 3. Discharges that exceed the numeric effluent limit for pH (outside the range of 6.5 â€“ 8.5 su) constitute a violation of this permit. 4. Permittees whose discharges exceed the numeric effluent limit shall sample discharges daily until the violation is corrected and comply with the non- compliance notification requirements in Special Condition S5.F. E. Sampling and Limits for Sites Discharging to Waters Covered by a TMDL or Another Pollution Control Plan 1. Discharges to a waterbody that is subject to a Total Maximum Daily Load (TMDL) for turbidity, fine sediment, high pH, or phosphorus must be consistent with the TMDL. Refer to http://www.ecy.wa.gov/programs/wq/tmdl/ TMDLsbyWria/TMDLbyWria.html for more information on TMDLs. a. Where an applicable TMDL sets specific waste load allocations or requirements for discharges covered by this permit, discharges must be consistent with any specific waste load allocations or requirements established by the applicable TMDL. i. The Permittee must sample discharges weekly or as otherwise specified by the TMDL to evaluate compliance with the specific waste load allocations or requirements. ii. Analytical methods used to meet the monitoring requirements must conform to the latest revision of the Guidelines Establishing Test Procedures for the Analysis of Pollutants contained in 40 CFR Part 136. Turbidity and pH methods need not be accredited or registered unless conducted at a laboratory which must otherwise be accredited or registered. b. Where an applicable TMDL has established a general waste load allocation for construction stormwater discharges, but has not identified specific requirements, Construction Stormwater General Permit Page 26 compliance with Special Conditions S4 (Monitoring) and S9 (SWPPPs) will constitute compliance with the approved TMDL. c. Where an applicable TMDL has not specified a waste load allocation for construction stormwater discharges, but has not excluded these discharges, compliance with Special Conditions S4 (Monitoring) and S9 (SWPPPs) will constitute compliance with the approved TMDL. d. Where an applicable TMDL specifically precludes or prohibits discharges from construction activity, the operator is not eligible for coverage under this permit. 2. Applicable TMDL means a TMDL for turbidity, fine sediment, high pH, or phosphorus that is completed and approved by EPA before January 1, 2016, or before the date the operatorâ€™s complete permit application is received by Ecology, whichever is later. TMDLs completed after the operatorâ€™s complete permit application is received by Ecology become applicable to the Permittee only if they are imposed through an administrative order by Ecology, or through a modification of permit coverage. S9. STORMWATER POLLUTION PREVENTION PLAN The Permittee must prepare and properly implement an adequate Stormwater Pollution Prevention Plan (SWPPP) for construction activity in accordance with the requirements of this permit beginning with initial soil disturbance and until final stabilization. A. The Permitteeâ€™s SWPPP must meet the following objectives: 1. To implement best management practices (BMPs) to prevent erosion and sedimentation, and to identify, reduce, eliminate or prevent stormwater contamination and water pollution from construction activity. 2. To prevent violations of surface water quality, ground water quality, or sediment management standards. 3. To control peak volumetric flow rates and velocities of stormwater discharges. B. General Requirements 1. The SWPPP must include a narrative and drawings. All BMPs must be clearly referenced in the narrative and marked on the drawings. The SWPPP narrative must include documentation to explain and justify the pollution prevention decisions made for the project. Documentation must include: a. Information about existing site conditions (topography, drainage, soils, vegetation, etc.). b. Potential erosion problem areas. c. The 13 elements of a SWPPP in Special Condition S9.D.1-13, including BMPs used to address each element. Construction Stormwater General Permit Page 27 d. Construction phasing/sequence and general BMP implementation schedule. e. The actions to be taken if BMP performance goals are not achievedâ€”for example, a contingency plan for additional treatment and/or storage of stormwater that would violate the water quality standards if discharged. f. Engineering calculations for ponds, treatment systems, and any other designed structures. When a treatment system requires engineering calculations, these calculations must be included in the SWPPP. Engineering calculations do not need to be included in the SWPPP for treatment systems that do not require such calculations. 2. The Permittee must modify the SWPPP if, during inspections or investigations conducted by the owner/operator, or the applicable local or state regulatory authority, it is determined that the SWPPP is, or would be, ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The Permittee must then: a. Review the SWPPP for compliance with Special Condition S9 and make appropriate revisions within 7 days of the inspection or investigation. b. Immediately begin the process to fully implement and maintain appropriate source control and/or treatment BMPs as soon as possible, addressing the problems no later than 10 days from the inspection or investigation. If installation of necessary treatment BMPs is not feasible within 10 days, Ecology may approve additional time when an extension is requested by a Permittee within the initial 10-day response period. c. Document BMP implementation and maintenance in the site log book. The Permittee must modify the SWPPP whenever there is a change in design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the State. C. Stormwater Best Management Practices (BMPs) BMPs must be consistent with: 1. Stormwater Management Manual for Western Washington (most current approved edition at the time this permit was issued), for sites west of the crest of the Cascade Mountains; or 2. Stormwater Management Manual for Eastern Washington (most current approved edition at the time this permit was issued), for sites east of the crest of the Cascade Mountains; or 3. Revisions to the manuals listed in Special Condition S9.C.1. & 2., or other stormwater management guidance documents or manuals which provide an equivalent level of pollution prevention, that are approved by Ecology and incorporated into this permit in accordance with the permit modification requirements of WAC 173-226-230; or Construction Stormwater General Permit Page 28 4. Documentation in the SWPPP that the BMPs selected provide an equivalent level of pollution prevention, compared to the applicable Stormwater Management Manuals, including: a. The technical basis for the selection of all stormwater BMPs (scientific, technical studies, and/or modeling) that support the performance claims for the BMPs being selected. b. An assessment of how the selected BMP will satisfy AKART requirements and the applicable federal technology-based treatment requirements under 40 CFR part 125.3. D. SWPPP â€“ Narrative Contents and Requirements The Permittee must include each of the 13 elements below in Special Condition S9.D.1-13 in the narrative of the SWPPP and implement them unless site conditions render the element unnecessary and the exemption from that element is clearly justified in the SWPPP. 1. Preserve Vegetation/Mark Clearing Limits a. Before beginning land-disturbing activities, including clearing and grading, clearly mark all clearing limits, sensitive areas and their buffers, and trees that are to be preserved within the construction area. b. Retain the duff layer, native topsoil, and natural vegetation in an undisturbed state to the maximum degree practicable. 2. Establish Construction Access a. Limit construction vehicle access and exit to one route, if possible. b. Stabilize access points with a pad of quarry spalls, crushed rock, or other equivalent BMPs, to minimize tracking sediment onto roads. c. Locate wheel wash or tire baths on site, if the stabilized construction entrance is not effective in preventing tracking sediment onto roads. d. If sediment is tracked off site, clean the affected roadway thoroughly at the end of each day, or more frequently as necessary (for example, during wet weather). Remove sediment from roads by shoveling, sweeping, or pickup and transport of the sediment to a controlled sediment disposal area. e. Conduct street washing only after sediment removal in accordance with Special Condition S9.D.2.d. Control street wash wastewater by pumping back on site or otherwise preventing it from discharging into systems tributary to waters of the State. 3. Control Flow Rates a. Protect properties and waterways downstream of development sites from erosion and the associated discharge of turbid waters due to increases in the Construction Stormwater General Permit Page 29 velocity and peak volumetric flow rate of stormwater runoff from the project site, as required by local plan approval authority. b. Where necessary to comply with Special Condition S9.D.3.a, construct stormwater retention or detention facilities as one of the first steps in grading. Assure that detention facilities function properly before constructing site improvements (for example, impervious surfaces). c. If permanent infiltration ponds are used for flow control during construction, protect these facilities from siltation during the construction phase. 4. Install Sediment Controls The Permittee must design, install and maintain effective erosion controls and sediment controls to minimize the discharge of pollutants. At a minimum, the Permittee must design, install and maintain such controls to: a. Construct sediment control BMPs (sediment ponds, traps, filters, infiltration facilities, etc.) as one of the first steps in grading. These BMPs must be functional before other land disturbing activities take place. b. Minimize sediment discharges from the site. The design, installation and maintenance of erosion and sediment controls must address factors such as the amount, frequency, intensity and duration of precipitation, the nature of resulting stormwater runoff, and soil characteristics, including the range of soil particle sizes expected to be present on the site. c. Direct stormwater runoff from disturbed areas through a sediment pond or other appropriate sediment removal BMP, before the runoff leaves a construction site or before discharge to an infiltration facility. Runoff from fully stabilized areas may be discharged without a sediment removal BMP, but must meet the flow control performance standard of Special Condition S9.D.3.a. d. Locate BMPs intended to trap sediment on site in a manner to avoid interference with the movement of juvenile salmonids attempting to enter off-channel areas or drainages. e. Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas to increase sediment removal and maximize stormwater infiltration, unless infeasible. f. Where feasible, design outlet structures that withdraw impounded stormwater from the surface to avoid discharging sediment that is still suspended lower in the water column. 5. Stabilize Soils a. The Permittee must stabilize exposed and unworked soils by application of effective BMPs that prevent erosion. Applicable BMPs include, but are not limited to: temporary and permanent seeding, sodding, mulching, plastic covering, erosion control fabrics and matting, soil application of polyacrylamide Construction Stormwater General Permit Page 30 (PAM), the early application of gravel base on areas to be paved, and dust control. b. The Permittee must control stormwater volume and velocity within the site to minimize soil erosion. c. The Permittee must control stormwater discharges, including both peak flow rates and total stormwater volume, to minimize erosion at outlets and to minimize downstream channel and stream bank erosion. d. Depending on the geographic location of the project, the Permittee must not allow soils to remain exposed and unworked for more than the time periods set forth below to prevent erosion: West of the Cascade Mountains Crest During the dry season (May 1 - September 30): 7 days During the wet season (October 1 - April 30): 2 days East of the Cascade Mountains Crest, except for Central Basin* During the dry season (July 1 - September 30): 10 days During the wet season (October 1 - June 30): 5 days The Central Basin*, East of the Cascade Mountains Crest During the dry season (July 1 - September 30): 30 days During the wet season (October 1 - June 30): 15 days *Note: The Central Basin is defined as the portions of Eastern Washington with mean annual precipitation of less than 12 inches. e. The Permittee must stabilize soils at the end of the shift before a holiday or weekend if needed based on the weather forecast. f. The Permittee must stabilize soil stockpiles from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels. g. The Permittee must minimize the amount of soil exposed during construction activity. h. The Permittee must minimize the disturbance of steep slopes. i. The Permittee must minimize soil compaction and, unless infeasible, preserve topsoil. 6. Protect Slopes a. The Permittee must design and construct cut-and-fill slopes in a manner to minimize erosion. Applicable practices include, but are not limited to, reducing continuous length of slope with terracing and diversions, reducing slope steepness, and roughening slope surfaces (for example, track walking). Construction Stormwater General Permit Page 31 b. The Permittee must divert off-site stormwater (run-on) or ground water away from slopes and disturbed areas with interceptor dikes, pipes, and/or swales. Off-site stormwater should be managed separately from stormwater generated on the site. c. At the top of slopes, collect drainage in pipe slope drains or protected channels to prevent erosion. i. West of the Cascade Mountains Crest: Temporary pipe slope drains must handle the peak 10-minute flow rate from a Type 1A, 10-year, 24-hour frequency storm for the developed condition. Alternatively, the 10-year, 1-hour flow rate predicted by an approved continuous runoff model, increased by a factor of 1.6, may be used. The hydrologic analysis must use the existing land cover condition for predicting flow rates from tributary areas outside the project limits. For tributary areas on the project site, the analysis must use the temporary or permanent project land cover condition, whichever will produce the highest flow rates. If using the Western Washington Hydrology Model (WWHM) to predict flows, bare soil areas should be modeled as "landscaped area.â€ ii. East of the Cascade Mountains Crest: Temporary pipe slope drains must handle the expected peak flow rate from a 6-month, 3-hour storm for the developed condition, referred to as the short duration storm. d. Place excavated material on the uphill side of trenches, consistent with safety and space considerations. e. Place check dams at regular intervals within constructed channels that are cut down a slope. 7. Protect Drain Inlets a. Protect all storm drain inlets made operable during construction so that stormwater runoff does not enter the conveyance system without first being filtered or treated to remove sediment. b. Clean or remove and replace inlet protection devices when sediment has filled one-third of the available storage (unless a different standard is specified by the product manufacturer). 8. Stabilize Channels and Outlets a. Design, construct and stabilize all on-site conveyance channels to prevent erosion from the following expected peak flows: i. West of the Cascade Mountains Crest: Channels must handle the peak 10-minute flow rate from a Type 1A, 10-year, 24-hour frequency storm for the developed condition. Alternatively, the 10-year, 1-hour flow rate indicated by an approved continuous runoff model, increased by a factor of 1.6, may be used. The hydrologic analysis must use the existing land Construction Stormwater General Permit Page 32 cover condition for predicting flow rates from tributary areas outside the project limits. For tributary areas on the project site, the analysis must use the temporary or permanent project land cover condition, whichever will produce the highest flow rates. If using the WWHM to predict flows, bare soil areas should be modeled as "landscaped area.â€ ii. East of the Cascade Mountains Crest: Channels must handle the expected peak flow rate from a 6-month, 3-hour storm for the developed condition, referred to as the short duration storm. b. Provide stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent stream banks, slopes, and downstream reaches at the outlets of all conveyance systems. 9. Control Pollutants Design, install, implement and maintain effective pollution prevention measures to minimize the discharge of pollutants. The Permittee must: a. Handle and dispose of all pollutants, including waste materials and demolition debris that occur on site in a manner that does not cause contamination of stormwater. b. Provide cover, containment, and protection from vandalism for all chemicals, liquid products, petroleum products, and other materials that have the potential to pose a threat to human health or the environment. On-site fueling tanks must include secondary containment. Secondary containment means placing tanks or containers within an impervious structure capable of containing 110% of the volume contained in the largest tank within the containment structure. Double- walled tanks do not require additional secondary containment. c. Conduct maintenance, fueling, and repair of heavy equipment and vehicles using spill prevention and control measures. Clean contaminated surfaces immediately following any spill incident. d. Discharge wheel wash or tire bath wastewater to a separate on-site treatment system that prevents discharge to surface water, such as closed-loop recirculation or upland land application, or to the sanitary sewer with local sewer district approval. e. Apply fertilizers and pesticides in a manner and at application rates that will not result in loss of chemical to stormwater runoff. Follow manufacturersâ€™ label requirements for application rates and procedures. f. Use BMPs to prevent contamination of stormwater runoff by pH-modifying sources. The sources for this contamination include, but are not limited to: bulk cement, cement kiln dust, fly ash, new concrete washing and curing waters, recycled concrete stockpiles, waste streams generated from concrete grinding and sawing, exposed aggregate processes, dewatering concrete vaults, concrete Construction Stormwater General Permit Page 33 pumping and mixer washout waters. (Also refer to the definition for "concrete wastewater" in Appendix A--Definitions.) g. Adjust the pH of stormwater or authorized non-stormwater if necessary to prevent an exceedance of groundwater and/or surface water quality standards. h. Assure that washout of concrete trucks is performed off-site or in designated concrete washout areas only. Do not wash out concrete truck drums or concrete handling equipment onto the ground, or into storm drains, open ditches, streets, or streams. Washout of concrete handling equipment may be disposed of in a designated concrete washout area or in a formed area awating concrete where it will not contaminate surface or ground water. Do not dump excess concrete on site, except in designated concrete washout areas. Concrete spillage or concrete discharge directly to groundwater or surface waters of the State is prohibited. Do not wash out to formed areas awaiting LID facilities. i. Obtain written approval from Ecology before using any chemical treatment, with the exception of CO2 or dry ice used to adjust pH. j. Uncontaminated water from water-only based shaft drilling for construction of building, road, and bridge foundations may be infiltrated provided the wastewater is managed in a way that prohibits discharge to surface waters. Prior to infiltration, water from water-only based shaft drilling that comes into contact with curing concrete must be neutralized until pH is in the range of 6.5 to 8.5 (su). 10. Control Dewatering a. Permittees must discharge foundation, vault, and trench dewatering water, which have characteristics similar to stormwater runoff at the site, into a controlled conveyance system before discharge to a sediment trap or sediment pond. b. Permittees may discharge clean, non-turbid dewatering water, such as well- point ground water, to systems tributary to, or directly into surface waters of the State, as specified in Special Condition S9.D.8, provided the dewatering flow does not cause erosion or flooding of receiving waters. Do not route clean dewatering water through stormwater sediment ponds. Note that â€œsurface waters of the Stateâ€ may exist on a construction site as well as off site; for example, a creek running through a site. c. Other dewatering treatment or disposal options may include: i. Infiltration. ii. Transport off site in a vehicle, such as a vacuum flush truck, for legal disposal in a manner that does not pollute state waters. Construction Stormwater General Permit Page 34 iii. Ecology-approved on-site chemical treatment or other suitable treatment technologies (see S9.D.9.i. regarding chemical treatment written approval). iv. Sanitary or combined sewer discharge with local sewer district approval, if there is no other option. v. Use of a sedimentation bag with discharge to a ditch or swale for small volumes of localized dewatering. d. Permittees must handle highly turbid or contaminated dewatering water separately from stormwater. 11. Maintain BMPs a. Permittees must maintain and repair all temporary and permanent erosion and sediment control BMPs as needed to assure continued performance of their intended function in accordance with BMP specifications. b. Permittees must remove all temporary erosion and sediment control BMPs within 30 days after achieving final site stabilization or after the temporary BMPs are no longer needed. 12. Manage the Project a. Phase development projects to the maximum degree practicable and take into account seasonal work limitations. b. Inspection and monitoring â€“ Inspect, maintain and repair all BMPs as needed to assure continued performance of their intended function. Conduct site inspections and monitoring in accordance with Special Condition S4. c. Maintaining an updated construction SWPPP â€“ Maintain, update, and implement the SWPPP in accordance with Special Conditions S3, S4 and S9. 13. Protect Low Impact Development (LID) BMPs The primary purpose of LID BMPs/On-site LID Stormwater Management BMPs is to reduce the disruption of the natural site hydrology. LID BMPs are permanent facilities. a. Permittees must protect all Bioretention and Rain Garden facilities from sedimentation through installation and maintenance of erosion and sediment control BMPs on portions of the site that drain into the Bioretention and/or Rain Garden facilities. Restore the facilities to their fully functioning condition if they accumulate sediment during construction. Restoring the facility must include removal of sediment and any sediment-laden Bioretention/Rain Garden soils, and replacing the removed soils with soils meeting the design specification. Construction Stormwater General Permit Page 35 b. Permittees must maintain the infiltration capabilities of Bioretention and Rain Garden facilities by protecting against compaction by construction equipment and foot traffic. Protect completed lawn and landscaped areas from compaction due to construction equipment. c. Permittees must control erosion and avoid introducing sediment from surrounding land uses onto permeable pavements. Do not allow muddy construction equipment on the base material or pavement. Do not allow sediment-laden runoff onto permeable pavements. d. Permittees must clean permeable pavements fouled with sediments or no longer passing an initial infiltration test using local stormwater manual methodology or the manufacturerâ€™s procedures. e. Permittees must keep all heavy equipment off existing soils under LID facilities that have been excavated to final grade to retain the infiltration rate of the soils. E. SWPPP â€“ Map Contents and Requirements The Permitteeâ€™s SWPPP must also include a vicinity map or general location map (for example, a USGS quadrangle map, a portion of a county or city map, or other appropriate map) with enough detail to identify the location of the construction site and receiving waters within one mile of the site. The SWPPP must also include a legible site map (or maps) showing the entire construction site. The following features must be identified, unless not applicable due to site conditions: 1. The direction of north, property lines, and existing structures and roads. 2. Cut and fill slopes indicating the top and bottom of slope catch lines. 3. Approximate slopes, contours, and direction of stormwater flow before and after major grading activities. 4. Areas of soil disturbance and areas that will not be disturbed. 5. Locations of structural and nonstructural controls (BMPs) identified in the SWPPP. 6. Locations of off-site material, stockpiles, waste storage, borrow areas, and vehicle/equipment storage areas. 7. Locations of all surface water bodies, including wetlands. 8. Locations where stormwater or non-stormwater discharges off-site and/or to a surface waterbody, including wetlands. 9. Location of water quality sampling station(s), if sampling is required by state or local permitting authority. Construction Stormwater General Permit Page 36 10. Areas where final stabilization has been accomplished and no further construction- phase permit requirements apply. 11. Location or proposed location of LID facilities. S10. NOTICE OF TERMINATION A. The site is eligible for termination of coverage when it has met any of the following conditions: 1. The site has undergone final stabilization, the Permittee has removed all temporary BMPs (except biodegradable BMPs clearly manufactured with the intention for the material to be left in place and not interfere with maintenance or land use), and all stormwater discharges associated with construction activity have been eliminated; or 2. All portions of the site that have not undergone final stabilization per Special Condition S10.A.1 have been sold and/or transferred (per General Condition G9), and the Permittee no longer has operational control of the construction activity; or 3. For residential construction only, the Permittee has completed temporary stabilization and the homeowners have taken possession of the residences. B. When the site is eligible for termination, the Permittee must submit a complete and accurate Notice of Termination (NOT) form, signed in accordance with General Condition G2, to: Department of Ecology Water Quality Program â€“ Construction Stormwater PO Box 47696 Olympia, Washington 98504-7696 When an electronic termination form is available, the Permittee may choose to submit a complete and accurate Notice of Termination (NOT) form through the Water Quality Permitting Portal rather than mailing a hardcopy as noted above. The termination is effective on the thirty-first calendar day following the date Ecology receives a complete NOT form, unless Ecology notifies the Permittee that the termination request is denied because the Permittee has not met the eligibility requirements in Special Condition S10.A. Permittees are required to comply with all conditions and effluent limitations in the permit until the permit has been terminated. Permittees transferring the property to a new property owner or operator/Permittee are required to complete and submit the Notice of Transfer form to Ecology, but are not required to submit a Notice of Termination form for this type of transaction. Construction Stormwater General Permit Page 37 GENERAL CONDITIONS G1. DISCHARGE VIOLATIONS All discharges and activities authorized by this general permit must be consistent with the terms and conditions of this general permit. Any discharge of any pollutant more frequent than or at a level in excess of that identified and authorized by the general permit must constitute a violation of the terms and conditions of this permit.

A written agreement (Transfer of Coverage Form) between the current discharger (Permittee) and new discharger, signed by both parties and containing a specific date for transfer of permit responsibility, coverage, and liability (including any Administrative Orders associated with the Permit) is submitted to the Director; and B. The Director does not notify the current discharger and new discharger of the Directorâ€™s intent to revoke coverage under the general permit. If this notice is not given, the transfer is effective on the date specified in the written agreement. When a current discharger (Permittee) transfers a portion of a permitted site, the current discharger must also submit an updated application form (NOI) to the Director indicating the remaining permitted acreage after the transfer. G10. REMOVED SUBSTANCES The Permittee must not re-suspend or reintroduce collected screenings, grit, solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of stormwater to the final effluent stream for discharge to state waters. G11. DUTY TO PROVIDE INFORMATION The Permittee must submit to Ecology, within a reasonable time, all information that Ecology may request to determine whether cause exists for modifying, revoking and reissuing, or terminating this permit or to determine compliance with this permit. The Permittee must also submit to Ecology, upon request, copies of records required to be kept by this permit [40 CFR 122.41(h)]. G12. OTHER REQUIREMENTS OF 40 CFR All other requirements of 40 CFR 122.41 and 122.42 are incorporated in this permit by reference. G13. ADDITIONAL MONITORING Ecology may establish specific monitoring requirements in addition to those contained in this permit by administrative order or permit modification. G14. PENALTIES FOR VIOLATING PERMIT CONDITIONS Any person who is found guilty of willfully violating the terms and conditions of this permit shall be deemed guilty of a crime, and upon conviction thereof shall be punished by a fine of up to ten thousand dollars ($10,000) and costs of prosecution, or by imprisonment at the discretion of the court. Each day upon which a willful violation occurs may be deemed a separate and additional violation. Construction Stormwater General Permit Page 41 Any person who violates the terms and conditions of a waste discharge permit shall incur, in addition to any other penalty as provided by law, a civil penalty in the amount of up to ten thousand dollars ($10,000) for every such violation. Each and every such violation shall be a separate and distinct offense, and in case of a continuing violation, every dayâ€™s continuance shall be deemed to be a separate and distinct violation. G15. UPSET Definition â€“ â€œUpsetâ€ means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based permit effluent limitations because of factors beyond the reasonable control of the Permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology-based permit effluent limitations if the requirements of the following paragraph are met. A Permittee who wishes to establish the affirmative defense of upset must demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: 1) an upset occurred and that the Permittee can identify the cause(s) of the upset; 2) the permitted facility was being properly operated at the time of the upset; 3) the Permittee submitted notice of the upset as required in Special Condition S5.F, and; 4) the Permittee complied with any remedial measures required under this permit. In any enforcement proceeding, the Permittee seeking to establish the occurrence of an upset has the burden of proof. G16. PROPERTY RIGHTS This permit does not convey any property rights of any sort, or any exclusive privilege. G17. DUTY TO COMPLY The Permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application. G18. TOXIC POLLUTANTS The Permittee must comply with effluent standards or prohibitions established under Section 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish those standards or prohibitions, even if this permit has not yet been modified to incorporate the requirement. Construction Stormwater General Permit Page 42 G19. PENALTIES FOR TAMPERING The Clean Water Act provides that any person who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required to be maintained under this permit shall, upon conviction, be punished by a fine of not more than $10,000 per violation, or by imprisonment for not more than two years per violation, or by both. If a conviction of a person is for a violation committed after a first conviction of such person under this condition, punishment shall be a fine of not more than $20,000 per day of violation, or imprisonment of not more than four (4) years, or both. G20. REPORTING PLANNED CHANGES The Permittee must, as soon as possible, give notice to Ecology of planned physical alterations, modifications or additions to the permitted construction activity. The Permittee should be aware that, depending on the nature and size of the changes to the original permit, a new public notice and other permit process requirements may be required. Changes in activities that require reporting to Ecology include those that will result in: A. The permitted facility being determined to be a new source pursuant to 40 CFR 122.29(b). B. A significant change in the nature or an increase in quantity of pollutants discharged, including but not limited to: for sites 5 acres or larger, a 20% or greater increase in acreage disturbed by construction activity. C. A change in or addition of surface water(s) receiving stormwater or non-stormwater from the construction activity. D. A change in the construction plans and/or activity that affects the Permitteeâ€™s monitoring requirements in Special Condition S4. Following such notice, permit coverage may be modified, or revoked and reissued pursuant to 40 CFR 122.62(a) to specify and limit any pollutants not previously limited. Until such modification is effective, any new or increased discharge in excess of permit limits or not specifically authorized by this permit constitutes a violation. G21. REPORTING OTHER INFORMATION Where the Permittee becomes aware that it failed to submit any relevant facts in a permit application, or submitted incorrect information in a permit application or in any report to Ecology, it must promptly submit such facts or information. G22. REPORTING ANTICIPATED NON-COMPLIANCE The Permittee must give advance notice to Ecology by submission of a new application or supplement thereto at least forty-five (45) days prior to commencement of such discharges, of any facility expansions, production increases, or other planned changes, such as process modifications, in the permitted facility or activity which may result in noncompliance with permit limits or conditions. Any maintenance of facilities, which might necessitate Construction Stormwater General Permit Page 43 unavoidable interruption of operation and degradation of effluent quality, must be scheduled during non-critical water quality periods and carried out in a manner approved by Ecology. G23. REQUESTS TO BE EXCLUDED FROM COVERAGE UNDER THE PERMIT Any discharger authorized by this permit may request to be excluded from coverage under the general permit by applying for an individual permit. The discharger must submit to the Director an application as described in WAC 173-220-040 or WAC 173-216-070, whichever is applicable, with reasons supporting the request. These reasons will fully document how an individual permit will apply to the applicant in a way that the general permit cannot. Ecology may make specific requests for information to support the request. The Director will either issue an individual permit or deny the request with a statement explaining the reason for the denial. When an individual permit is issued to a discharger otherwise subject to the construction stormwater general permit, the applicability of the construction stormwater general permit to that Permittee is automatically terminated on the effective date of the individual permit. G24. APPEALS A. The terms and conditions of this general permit, as they apply to the appropriate class of dischargers, are subject to appeal by any person within 30 days of issuance of this general permit, in accordance with Chapter 43.21B RCW, and Chapter 173-226 WAC. B. The terms and conditions of this general permit, as they apply to an individual discharger, are appealable in accordance with Chapter 43.21B RCW within 30 days of the effective date of coverage of that discharger. Consideration of an appeal of general permit coverage of an individual discharger is limited to the general permitâ€™s applicability or nonapplicability to that individual discharger. C. The appeal of general permit coverage of an individual discharger does not affect any other dischargers covered under this general permit. If the terms and conditions of this general permit are found to be inapplicable to any individual discharger(s), the matter shall be remanded to Ecology for consideration of issuance of an individual permit or permits. G25. SEVERABILITY The provisions of this permit are severable, and if any provision of this permit, or application of any provision of this permit to any circumstance, is held invalid, the application of such provision to other circumstances, and the remainder of this permit shall not be affected thereby. G26. BYPASS PROHIBITED A. Bypass Procedures Bypass, which is the intentional diversion of waste streams from any portion of a treatment facility, is prohibited for stormwater events below the design criteria for Construction Stormwater General Permit Page 44 stormwater management. Ecology may take enforcement action against a Permittee for bypass unless one of the following circumstances (1, 2, 3 or 4) is applicable. 1. Bypass of stormwater is consistent with the design criteria and part of an approved management practice in the applicable stormwater management manual. 2. Bypass for essential maintenance without the potential to cause violation of permit limits or conditions. Bypass is authorized if it is for essential maintenance and does not have the potential to cause violations of limitations or other conditions of this permit, or adversely impact public health. 3. Bypass of stormwater is unavoidable, unanticipated, and results in noncompliance of this permit. This bypass is permitted only if: a. Bypass is unavoidable to prevent loss of life, personal injury, or severe property damage. â€œSevere property damageâ€ means substantial physical damage to property, damage to the treatment facilities which would cause them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. b. There are no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, maintenance during normal periods of equipment downtime (but not if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventative maintenance), or transport of untreated wastes to another treatment facility. c. Ecology is properly notified of the bypass as required in Special Condition S5.F of this permit. 4. A planned action that would cause bypass of stormwater and has the potential to result in noncompliance of this permit during a storm event. The Permittee must notify Ecology at least thirty (30) days before the planned date of bypass. The notice must contain: a. A description of the bypass and its cause. b. An analysis of all known alternatives which would eliminate, reduce, or mitigate the need for bypassing. c. A cost-effectiveness analysis of alternatives including comparative resource damage assessment. d. The minimum and maximum duration of bypass under each alternative. e. A recommendation as to the preferred alternative for conducting the bypass. Construction Stormwater General Permit Page 45 f. The projected date of bypass initiation. g. A statement of compliance with SEPA. h. A request for modification of water quality standards as provided for in WAC 173-201A-110, if an exceedance of any water quality standard is anticipated. i. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. 5. For probable construction bypasses, the need to bypass is to be identified as early in the planning process as possible. The analysis required above must be considered during preparation of the Stormwater Pollution Prevention Plan (SWPPP) and must be included to the extent practical. In cases where the probable need to bypass is determined early, continued analysis is necessary up to and including the construction period in an effort to minimize or eliminate the bypass. Ecology will consider the following before issuing an administrative order for this type bypass: a. If the bypass is necessary to perform construction or maintenance-related activities essential to meet the requirements of this permit. b. If there are feasible alternatives to bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, stopping production, maintenance during normal periods of equipment down time, or transport of untreated wastes to another treatment facility. c. If the bypass is planned and scheduled to minimize adverse effects on the public and the environment. After consideration of the above and the adverse effects of the proposed bypass and any other relevant factors, Ecology will approve, conditionally approve, or deny the request. The public must be notified and given an opportunity to comment on bypass incidents of significant duration, to the extent feasible. Approval of a request to bypass will be by administrative order issued by Ecology under RCW 90.48.120. B. Duty to Mitigate The Permittee is required to take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit that has a reasonable likelihood of adversely affecting human health or the environment.

May be "time-composite" (collected at constant time intervals) or "flow-proportional" (collected either as a constant sample volume at time intervals proportional to stream flow, or collected by increasing the volume of each aliquot as the flow increases while maintaining a constant time interval between the aliquots. Concrete Wastewater means any water used in the production, pouring and/or clean-up of concrete or concrete products, and any water used to cut, grind, wash, or otherwise modify concrete or concrete products. Examples include water used for or resulting from concrete truck/mixer/pumper/tool/chute rinsing or washing, concrete saw cutting and surfacing (sawing, coring, grinding, roughening, hydro-demolition, bridge and road surfacing). When stormwater comingles with concrete wastewater, the resulting water is considered concrete wastewater and must be managed to prevent discharge to waters of the State, including ground water. Construction Activity means land disturbing operations including clearing, grading or excavation which disturbs the surface of the land. Such activities may include road construction, construction of residential houses, office buildings, or industrial buildings, site preparation, soil compaction, movement and stockpiling of topsoils, and demolition activity.

Pollution means contamination or other alteration of the physical, chemical, or biological properties of waters of the State; including change in temperature, taste, color, turbidity, or odor of the waters; or such discharge of any liquid, gaseous, solid, radioactive or other substance into any waters of the State as will or is likely to create a nuisance or render such waters harmful, detrimental or injurious to the public health, safety or welfare; or to domestic, commercial, industrial, agricultural, recreational, or other legitimate beneficial uses; or to livestock, wild animals, birds, fish or other aquatic life. Process Wastewater means any water which, during manufacturing or processing, comes into direct contact with or results from the production or use of any raw material, intermediate product, finished product, byproduct, or waste product. If stormwater commingles with process wastewater, the commingled water is considered process wastewater. Receiving Water means the waterbody at the point of discharge. If the discharge is to a storm sewer system, either surface or subsurface, the receiving water is the waterbody to which the storm system discharges. Systems designed primarily for other purposes such as for ground water drainage, redirecting stream natural flows, or for conveyance of irrigation water/return flows that coincidentally convey stormwater are considered the receiving water. Construction Stormwater General Permit Page 51 Representative means a stormwater or wastewater sample which represents the flow and characteristics of the discharge. Representative samples may be a grab sample, a time- proportionate composite sample, or a flow proportionate sample. Ecologyâ€™s Construction Stormwater Monitoring Manual provides guidance on representative sampling.

Percentages of the total maximum daily load are allocated to the various pollutant sources. A TMDL is the sum of the allowable loads of a single pollutant from all contributing point and nonpoint sources. The TMDL calculations must include a "margin of safety" to ensure that the waterbody can be protected in case there are unforeseen events or unknown sources of the pollutant.

The transparency tube is used to estimate the relative clarity or transparency of water by noting the depth at which a black and white Secchi disc becomes visible when water is released from a value in the bottom of the tube. A transparency tube is sometimes referred to as a â€œturbidity tube.â€ Turbidity means the clarity of water expressed as nephelometric turbidity units (NTUs) and measured with a calibrated turbidimeter. Uncontaminated means free from any contaminant. See definition of â€œcontaminantâ€ and WAC 173-340-200. Waste Load Allocation (WLA) means the portion of a receiving waterâ€™s loading capacity that is allocated to one of its existing or future point sources of pollution. WLAs constitute a type of water quality based effluent limitation (40 CFR 130.2[h]). Water-only Based Shaft Drilling is a shaft drilling process that uses water only and no additives are involved in the drilling of shafts for construction of building, road, or bridge foundations. Water quality means the chemical, physical, and biological characteristics of water, usually with respect to its suitability for a particular purpose. Waters of the State includes those waters as defined as "waters of the United States" in 40 CFR Subpart 122.2 within the geographic boundaries of Washington State and "waters of the State" as defined in Chapter 90.48 RCW, which include lakes, rivers, ponds, streams, inland waters, underground waters, salt waters, and all other surface waters and water courses within the jurisdiction of the state of Washington. Well means a bored, drilled or driven shaft, or dug hole whose depth is greater than the largest surface dimension. (See Injection well.) Wheel Wash Wastewater means any water used in, or resulting from the operation of, a tire bath or wheel wash (BMP C106: Wheel Wash), or other structure or practice that uses water to physically remove mud and debris from vehicles leaving a construction site and prevent track- out onto roads.

The receiving water is not listed 303(d) (Category 5) for turbidity, fine sediment, phosphorus, or PH. G. Contaminated Site Information Not Applicable to this project. H. Engineering Calculations The site will utilize Volume II of the 2014 DOE SMMWW for the erosion and sedimentation control design to reduce the discharge of sediment-laden runoff from the site. Clearing limits will be established prior to any earthwork on the project site. Perimeter protection will be provided by silt fencing along the downstream perimeter of the disturbed areas to limit the downstream transport of sediment to streams, wetlands and neighboring properties. Dust control, if required, will be provided by a water truck. A Certified Erosion and Sediment Control Lead inspector will be present onsite during earthwork activities. The inspector shall determine frequency of watering of the project site and will authorize and direct any additional erosion and sediment control measures as needed during all construction activities. The plan will be comprised of temporary measures (stabilized construction entrance, silt fence, interceptor swales, etc.) as well as permanent measures (detention ponds, hydroseeding, etc.). In general, construction activities will be sequenced such that the permanent detention pond will be constructed and used for temporary erosion and sedimentation control. Runoff from the site will sheet flow across cleared areas into temporary interceptor swales and into temporary pipes that discharge into the permanent detention pond or into the permanent conveyance system, when installed. Although the permanent detention pond will be used as the TESC pond for the project, the minimum TESC pond area, dewatering orifice diameter, and emergency spillway length are calculated below and compared to the proposed detention ponds to verify adequate TESC functionality. The TESC pond area was calculated for the project site using the 10-year storm event with the potential of work during the wet season (October 1 to April 30). The 10-year time step developed condition peak flow rate used for TESC pond area sizing is Q10 = 3.97 cfs TESC Pond Surface Area Calculations TESC Pond minimum surface area SA, is determined by the following equation: SA = 2080 sf/cfs * (Total Q10-developed) Where: SA = minimum TESC pond surface area (sf) Q10-developed = 10-year developed peak flow (3.97 cfs) SAmin = 8,258 sf The design bottom surface area of the proposed wetpond that will but used for TESC = 10,230 sf. â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€” MGS FLOOD PROJECT REPORT Program Version: MGSFlood 4.50 Program License Number: 200210008 Project Simulation Performed on: 03/23/2020 1:44 PM Report Generation Date: 03/23/2020 1:45 PM â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€” Input File Name: 19035 TESC Pond.fld Project Name: Analysis Title: Comments: â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€” PRECIPITATION INPUT â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€”â€” Computational Time Step (Minutes): 15 Extended Precipitation Time Series Selected Climatic Region Number: 17 Full Period of Record Available used for Routing Precipitation Station : 96004805 Puget East 48 in_5min 10/01/1939-10/01/2097 Evaporation Station : 961048 Puget East 48 in MAP Evaporation Scale Factor : 0.750 HSPF Parameter Region Number: 1 HSPF Parameter Region Name : USGS Default ********** Default HSPF Parameters Used (Not Modified by User) *************** ********************** WATERSHED DEFINITION *********************** Predevelopment/Post Development Tributary Area Summary Predeveloped Post Developed Total Subbasin Area (acres) 13.660 13.660 Area of Links that Include Precip/Evap (acres) 0.000 0.000 Total (acres) 13.660 13.660 ----------------------SCENARIO: PREDEVELOPED Number of Subbasins: 1 ---------- Subbasin : Subbasin 1 ---------- -------Area (Acres) -------- Till Forest 13.660 ---------------------------------------------- Subbasin Total 13.660 ----------------------SCENARIO: POSTDEVELOPED Number of Subbasins: 1 ---------- Subbasin : Subbasin 2 ---------- -------Area (Acres) -------- Till Grass 13.660 ---------------------------------------------- Subbasin Total 13.660 ************************* LINK DATA ******************************* ----------------------SCENARIO: PREDEVELOPED Number of Links: 1 ------------------------------------------ Link Name: New Copy Lnk1 Link Type: Copy Downstream Link: None ************************* LINK DATA ******************************* ----------------------SCENARIO: POSTDEVELOPED Number of Links: 1 ------------------------------------------ Link Name: New Structure Lnk1 Link Type: Structure Downstream Link: None Prismatic Pond Option Used Pond Floor Elevation (ft) : 100.00 Riser Crest Elevation (ft) : 104.00 Max Pond Elevation (ft) : 105.00 Storage Depth (ft) : 4.00 Pond Bottom Length (ft) : 300.0 Pond Bottom Width (ft) : 150.0 Pond Side Slopes (ft/ft) : L1= 3.00 L2= 3.00 W1= 3.00 W2= 3.00 Bottom Area (sq-ft) : 45000.

PROJECT OVERVIEW The Gilman Walk at Country Charm project site consists of one parcel with a total area 21.22 acres and is located in Snohomish County within the City of Arlington. More specifically, the site is located in SW quarter of Section 1, Township 31, Range 5 East, W.M., just east of Alcazar Avenue and north of Park Hill Drive. The site is bound by single family residences to the south and Alcazar Avenue to the west. North and east of the project site is city property that is within the floodplain for the Stillaguamish River. The project site currently contains a paved access road with a barn on the west side of the site and a single family residence on the east side of the site. The rest of the site is covered in grass and gravel with trees covering the slopes along the north and east property lines. See Figure 1.1 at the end of this section for a vicinity map. The King County tax parcel ID numbers for the project site is located in Table 1.1 below. (Refer to the King County parcel reports included at the end of this section). Table 1.1 Snohomish County Parcel ID Parcel # Parcel Area (acres) 31050100302200 21.22 31050100300200 0.18 Total: 21.40 The property is located entirely within the Stillaguamish River Basin. Refer to Section 3 of this report for a description of the offsite analysis. Steep slopes exist on the north and east property lines, sloping away from the site. The rest of the site slopes generally to the north at slight to moderate grades. The proposed development will include multiple duplex, triplex and four-plex structures that will contain up to a total of 115 units with associated roads and utilities. The project will connect to E Gilman Avenue and E Division Street at the west property line near the southwest corner of the site. The project is located within the City of Arlington and is subject to the requirements presented in the 2012 Stormwater Management Manual for Western Washington (SMMWW) as amended in 2014. The drainage analysis for detention sizing has been modeled using the MGS Flood modeling program, an approved model per the manual. Core Design, Inc.

CONDITIONS AND REQUIREMENTS SUMMARY The project will be designed using the guidelines and requirements established in the 2014 SMMWW. This is a multifamily residential project which proposes greater than 5,000 square feet of new hard surface area, therefore requiring the project to demonstrate compliance with all nine (9) minimum requirements. 2.1 Minimum Requirements 2.1.1 Minimum Requirement #1: Preparation of Stormwater Site Plans Civil Plans under separate cover and a Final Storm Drainage Report herein have been prepared for the subject project. 2.1.2 Minimum Requirement #2: Construction Stormwater Pollution Prevention All 12 elements to be addressed. A Temporary Erosion and Sediment Control (TESC) plan has been included with the Civil Plans and a SWPPP has been provided under separate cover. 2.1.3 Minimum Requirement #3: Source Control of Pollution This minimum requirement applies to the construction activities for this project. The BMPs proposed are shown on the TESC plans and described in the SWPPPP report, both of which have been provided under separate cover. 2.1.4 Minimum Requirement #4: Preservation of Natural Drainage Systems and Outfalls Discharge from the site is to the existing natural discharge location which is the undeveloped land north of the site that drains to the Stillaguamish River. 2.1.5 Minimum Requirements #5: On-site Stormwater Management Stormwater BMP design is discussed in Section 4.1 of this report. The required BMPs are determined using the flow chart in Figure 4.1 in Section 4.1 of this report. 2.1.6 Minimum Requirement #6: Runoff Treatment The project is a multi-family residential project and therefore is required to provide enhanced water quality treatment. The project proposes to regrade the existing pond in order to provide enhanced treatment for stormwater runoff. The pond will meet the requirements for a Stormwater Treatment Wetland. Designs for the treatment facilities are described in Section 4 of this report. 2.1.7 Minimum Requirement #7: Flow Control Flow control is addressed in Section 4 of this report. The project proposes to discharge directly to a flow control-exempt surface water and is therefore not required to provide a flow control facility. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 2-1 2.1.8 Minimum Requirement #8: Wetland Protection There is wetland area offsite to the north of the project. The project proposes to convey stormwater runoff outside of the wetland area and its buffer and into the existing pond. Therefore, the project will have no effect on the wetland or its buffer. 2.1.9 Minimum Requirement #9: Operation and Maintenance This minimum requirement is addressed in Section 10 of this report. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 2-2 SECTION 3. OFFSITE ANALYSIS A level 1 downstream analysis was performed on the project site. All related tasks are addressed below. TASK 1 Study Area Definition and Maps The proposed project contains parcel numbers 31050100302200 and 31050100300200. Refer to the property report located at the end of Section 1. TASK 2 Resource Review Basin Reconnaissance Summary Reports No Basin Reconnaissance Summary Reports appear to be available for the area that is within one mile of this project site. FEMA Maps A FEMA map dated November 8, 1999 number 53061C0405E was reviewed. The developable site is not located within a floodplain as it is covered by â€œZone X â€“ Outside of 500-year floodplainâ€. The FEMA Map is included at the end of this section. USDA Natural Resources Conservation Service Soil Survey The USDA Natural Resources Conservation Service (NRCS) Web Soil Survey covers the project site area. The Soils Map exhibit is included at the end of this section. TASK 3 Field Investigation Tributary Area The entire site generally slopes toward the north. The eastern third of the project site slopes towards the property boundary to the north and east. Steep slopes exist at the north and east property lines towards the country charm conservation area. Upstream Tributary Analysis A small amount of upstream drainage is tributary to the project site from a mostly undeveloped neighboring parcel at the south property line. TASK 4 Drainage System Description and Problem Description A downstream analysis was performed on Thursday October 10th, 2019. The weather was sunny and approximately 55 degrees. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 3-1 A Level 1 downstream analysis was performed on the project site. The site is currently partially developed with a barn structure at the southwest corner of the site and a residential structure at the northeast corner. A paved road accesses the site at the west property line connecting to East Gilman Avenue and continues through the project site to the northeast corner. Much of the site adjacent to the roadway is covered in grass and gravel with a pit containing concrete rubble in one area. The rest of the site is covered in trees. The entire site is located within the Stillaguamish River drainage basin. The majority of the site generally slopes to the north with north facing steep slopes at the north and south property lines. At the northeast corner of the site, the existing ground slopes steeply to the north and to the east towards the property lines and continues offsite. Immediately offsite to the north and east is the Country Charm Conservation area which is undeveloped and part on the floodplain for the Stillaguamish River. An existing pond is located offsite just north of the project. The Country Charm Conservation area is flat and is entirely tributary to the South Fork Stillaguamish River. Due to the existing slopes on site, stormwater runoff leaves the site in two direction, north and east. North Discharge: Stormwater runoff from a majority of the site flows to the north until reaching the steep slopes along the north property line. There is a manmade ditch along the north property line at the foot of the steep slopes that intercepts runoff and directs stormwater west, eventually discharging into the South Fork of the Stillaguamish River. The overflow route for the pond is the manmade ditch. The ditch carries stormwater approximately 1,500 feet from the pond to the South Fork Stillaguamish River. East Discharge: Area near the east property line slopes towards the east down the existing steep slopes. Just east of the site is another existing wetland that detains stormwater. Runoff leaving the wetland continues through a creek that flows to the north. The creek flows north for approximately Â½-mile before entering the South Fork Stillaguamish River. In summary, both discharge locations converge at a point less than Â¼-mile downstream of the project site in the Stillaguamish River, and is therefore considered a single basin. Refer to Figure 4-1: Existing Conditions Exhibit and Figure 4.2: Developed Conditions Exhibit in Section 4 for the basin map. Flow Control Exemption The project is exempt from Minimum Requirement #7: Flow Control because it drains to a flow control exempt surface water and meets the corresponding restrictions described in Appendix I-E of the 2014 SMMWW. A discussion showing compliance with these restrictions is included below. â€¢ Direct discharge to an exempt receiving water does not result in the diversion of drainage from any perennial stream classified as Types 1, 2, 3, or 4 in the State of Washington Interim Water Typing System, or Types â€œSâ€, â€œFâ€ or â€œNpâ€ in the Permanent Water Typing System, or from any category I, II, or III wetland. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 3-2 Response: The project does not propose to divert flows from any of the stream types listed as all stormwater runoff will be discharged to the natural outfall location of the site per Minimum Requirement #4. â€¢ Flow splitting devices or drainage BMPâ€™s are applied to route natural runoff volumes from the project site to any downstream Type 5 stream or category IV wetland: o Design of flow splitting devices or drainage BMPâ€™s will be based on continuous hydrologic modeling analysis. The design will assure that flows delivered to Type 5 stream reaches will approximate, but in no case exceed, durations ranging from 50% of the 2-year to the 50-year peak flow. o Flow splitting devices or drainage BMPâ€™s that deliver flow to category IV wetlands will also be designed using continuous hydrologic modeling to preserve pre-project wetland hydrologic conditions unless specifically waived or exempted by regulatory agencies with permitting jurisdiction. Response: According to the Wetland Assessment Report completed by Soundview Consultants, there are no Type 5 streams or Category IV wetlands downstream of the project site before reaching the flow control exempt receiving water. This report has been submitted under separate cover. â€¢ The project site must be drained by a conveyance system that is comprised entirely of manmade objects (e.g., pipes, ditches, outfall protection) and extends to the ordinary high water mark of the exempt receiving water. Response: The project site will be drained using a piped conveyance system until reaching the stormwater treatment wetland constructed as part of this project for water quality treatment. From this point, the runoff will travel west through a manmade ditch until reaching the ordinary high water mark of the South Fork Stillaguamish River. â€¢ The conveyance system between the project site and the exempt receiving water shall have a hydraulic capacity sufficient to convey discharges from future build-out conditions (under current zoning) of the site, and the existing condition from non-project areas from which runoff is or will be collected. Response: Conveyance and backwater calculations for the on-site conveyance system are provided in Section 5 of this report and show that the on-site system has sufficient capacity. The off-site ditch used for conveyance does not show evidence of flooding historically, however in the case that the ditch overflows, runoff will sheet flow through open pasture until reaching the same outfall location. â€¢ Any erodible elements of the manmade conveyance system must be adequately stabilized to prevent erosion under the conditions noted above. In the case of overflow of the ditch downstream of the stormwater treatment wetland, runoff will sheetflow across pasture located Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 3-3 on private property until reaching the Stillaguamish River. Any overflow in this area does not risk damaging property. Response: Outfall protection from the stormwater treatment wetland and energy dissipaters will be implemented to prevent erosion. The ditch downstream of the stormwater treatment wetland will be further stabilized if required. Core Design, Inc.

FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN 4.1 Project LID Feasibility Per Minimum Requirement #5, the project shall implement on-site stormwater management BMPs in accordance with the 2014 SMMWW. The flow chart below is used to determine the BMP requirements for the project. Figure 4.1: Flow Chart for Determining LID MR #5 Requirements Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-1 This project directly discharges to the South Fork Stillaguamish River, a flow control exempt surface water per Minimum Requirement #7. Therefore the project is not required to meet the LID Performance Standard, or apply the BMPs from list #1 and #2 of Section 1-2.5.5 of the 2014 SMMWW. The project will implement the following BMPs where feasible as required by Figure 4.1 above: â€¢ BMP T5.13: Post-Construction Soil Quality and Depth Response: This BMP will be implemented for all lawn and landscaped areas that are affected by construction and grading activities in accordance with BMP T5.13 in the 2014 SMMWW. â€¢ BMP T5.10A: Downspout Full Infiltration Response: The soils on-site do not support infiltration facilities as determined by a geotechnical engineer, therefore the BMP is not applicable. Refer to the Geotechnical Report submitted under separate cover. â€¢ BMPT5.10B: Downspout Dispersion Systems Response: The project site cannot support the required flowpath for full dispersion due to site constraints. This BMP is not applicable. â€¢ BMP T5.10C: Perforated Stub-out Connections Response: Perforated stub-out connections will be implemented wherever feasible per a geotechnical review. â€¢ BMP T5.11: Concentrated Flow Dispersion Response: Due to the steep slopes located on site, the project cannot support the required vegetated flow path for Concentrated Flow Dispersion. â€¢ BMP T5.12: Sheet Flow Dispersion Response: Sheet flow dispersion is proposed for areas that can support the required flow path, such as the proposed trail. 4.2 Hydraulic Analysis All stormwater facilities will be designed in accordance with the 2014 SMMWW. The drainage analysis for detention and water quality sizing was modeled using the MGS Flood modeling program. 4.2.1 Existing Conditions The 21.40-acre project site contains two single family structures with several barns located on site. A paved access road, Gilman Avenue, provides access to the site and continues across the site to the Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-2 northeast. The rest of the site contains gravel and trees, with steep slopes along the north and east property lines. The predeveloped condition has been modeled using historic site conditions. Table 4-1 below shows that the entire site has been modeled as Forested using the MGS Flood software. Only areas that are subject to grading activities in the developed condition are considered in the predeveloped condition. A total of 13.66 acres of the 21.40 acre site is included in the developed basin. Critical areas and forested area that is not proposed to be cleared are left out of the predeveloped basin. Table 4-1 Predeveloped Areas GROUND COVER TOTAL (acres) Forested 13.66 Refer to the MGS Flood report located in the Appendix. 4.2.2 Developed Conditions The project proposes the construction of multi-family residential structures with associated roads and utilities. Access to the site will be provided by a proposed roadway that will connect to East Gilman Avenue at the west property line. The project is exempt from providing a flow control facility per Minimum Requirement #7 as the project can discharge directly to the Stillaguamish River, which is listed as a flow control exempt surface water in Table I-E.1 Exempt Surface Waters List in the 2014 SMMWW. The project will collect and convey stormwater runoff to an existing pond north of the project site that will be regraded and used for water quality purposes. Refer to Section 4.4 for more information on runoff treatment. This discharge point also matches the natural discharge location for the existing site, meeting Minimum Requirement #4. Table 4-2 below shows the areas proposed as part of this project. Also refer to the Developed Conditions Exhibit for a visual of these on-site areas.

Wetland Protection There is a wetland area at the foot of the steep slopes adjacent to the north property line. The wetland is offsite and will not be affected by the project. Stormwater runoff from the project site will be collected and conveyed outside of the wetland area and its respective buffer before discharging into the existing wetpond. The outlet from the wetpond will be outside of the wetland and its buffer, therefore the wetland will remain unaffected by the project. The channel that receives the discharge from the wetpond is vegetated and stable, no additional improvements are proposed. Minimum Requirement #8 applies only to projects whose stormwater discharges into a wetland, either directly or indirectly through a conveyance system, therefore no further requirements apply. 4.3 Detention Calculations The project is not required to meet Minimum Requirement #7: Flow Control as stormwater runoff will be discharged directly to a flow control exempt surface water. Refer to Section 3 of this report for justification of the flow control exemption for this project. Stormwater will be detained in the existing wetpond located north of the project site for water quality purposes only. Refer to Section 4.5 for information regarding water quality for this project.

Per the 2014 SMMWW, enhanced treatment is required for multi-family residential and commercial projects. The project is a multi-family residential project and therefore must provide Enhanced Treatment. The flow chart below from the 2014 SMMWW assists in selecting a water quality facility for the site. Water Quality Facility Flow Chart Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-7 Following the flow chart, the project must select an enhanced treatment facility from the list provided. The project elects to implement a Stormwater Treatment Wetland. The existing wetpond located north of the project site will be regraded as part of this project to meet the requirements of a Stormwater Treatment Wetland per BMP T10.30 in the 2014 SMMWW and ensure proper function and storage capacity. Sizing information for the stormwater treatment wetland is provided below. Stormwater Treatment Wetland A Stormwater Treatment Wetland is proposed to meet the enhanced treatment water quality requirement. The project will collect and convey stormwater runoff to the existing wetpond that will be regraded as part of this project. The treatment wetland water quality facility will be sized using the procedure provided in Chapter V-10 of the 2014 SMMWW (BMP T10.30). 1. The volume of a basic wetpond is used as a template for sizing the stormwater wetland. The design volume is the total volume of runoff from the 6-month, 24-hour storm event. Alternatively, use the Water Quality Design Storm Volume estimated by an approved continuous runoff model. The water quality design storm volume estimated using MGS Flood is used and is shown below. Basic Wet Pond Volume (91% Exceedance): 44716. cu-ft 2. Calculate the surface area of the stormwater wetland. The surface area of the wetland shall be the same as the top area of a wetpond sized for the same site conditions. Calculate the surface area of the stormwater wetland by using the volume from Step 1 and dividing by the average water depth (use 3 feet). 44,716 ð‘ð‘ð‘ð‘ ð‘†ð‘†ð‘†ð‘† = = 14,906 ð‘ ð‘ ð‘ð‘ 3 ð‘ð‘ð‘“ð‘“ 3. Determine the surface area of the first cell of the stormwater wetland. Use the volume determined from Criterion 2 under â€œWetland Geometryâ€, and the actual depth of the first cell. Criterion 2 states that the presettling cell shall contain approximately 33% of the wetpool volume calculated in Step 1. ð‘‰ð‘‰ = 44,716âˆ—0.33 = 14,756 For a 5 foot deep presettling cell, the minimum required surface area is 2,951 square feet. The provided surface area of the presettling cell is 5,225 square feet. 4. Determine the surface area of the wetland cell. Subtract the surface area of the first cell (Step 3) from the total surface area (Step 2). ð‘Šð‘Šð‘Šð‘Šð‘“ð‘“ð‘Šð‘Šð‘Šð‘Šð‘Šð‘Šð‘Šð‘Š ð‘†ð‘†ð‘†ð‘† = 14,906âˆ’2951 = 11,955 ð‘ ð‘ ð‘ð‘ Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-8 The minimum required surface area for the wetland cell is 11,955 sf. The surface area provided for the wetland cell is 12,100 sf. 5. Determine water depth distribution in the second cell. Decide if the top of the dividing berm will be at the surface or submerged. Adjust the distribution of water depths in the second cell according to Criterion 8 under â€œWetland Geometryâ€. Note: This will result in a facility that holds less volume that the determined in Step 1 above. This is acceptable. The dividing berm will be placed at the water surface elevation, therefore the distribution of depths will be configured as follows from Table V-10.3.2: Depth Range (feet) Percent 0.1 to 1 25 1 to 2 55 2 to 2.5 20 6. Choose plants. See Table V-10.3.1 Emergent Wetland Plant Species Recommended for Wetponds for a list of plants recommended for wetpond water depth zones, or consult a wetland scientist. The wetland plants selected are shown on the landscape plans submitted under separate cover. Core Design, Inc. GILMAN WALK AT COUNTRY CHARM Page 4-9 SECTION 5. CONVEYANCE SYSTEM ANALYSIS AND DESIGN The tight-lined storm drainage system for the site was designed for the 25-year storm utilizing the Rational Method per the 2017 WSDOT Hydraulics Manual. Backwater Analyses were completed using the flows tabulated in the rational method calculated conveyance spreadsheets. The total site area was delineated into separate basins for each storm structure in order to evaluate the capacity of the system. A weighted runoff coefficient â€œCâ€ was calculated for the entire site based on surface types. This value was determined using the following equation: ð¼ð¼(ð¶ð¶ð¼ð¼)+ð‘ƒð‘ƒ(ð¶ð¶ð‘ƒð‘ƒ) ð¶ð¶ = ð¼ð¼ +ð‘ƒð‘ƒ Where: I = Impervious area in acres in the developed condition P = Pervious area in acres in the developed condition CI = Runoff coefficient for impervious area type, Rational Method CI = 0.9 for pavement and roofs CP = Runoff coefficient for pervious area type, Rational Method CP = 0.25 for lawns (Table 3.2.1.A) (6.53âˆ—0.9)+(7.13âˆ—0.25) ð¶ð¶ = 6.53+7.13 ð‘ªð‘ª = ðŸŽðŸŽ.ðŸ“ðŸ“ðŸ“ðŸ“ The conveyance and backwater calculations are provided in the following pages. Also refer to Figure 5-1 at the end of this section for basin areas of each drainage structure. The conveyance calculations will show that the conveyance system can safely convey stormwater runoff to the offsite wetpond without overtopping during the 25-year design storm. Core Design, Inc.

ESC ANALYSIS AND DESIGN A CSWPPP will be prepared and submitted under separate cover prior to final engineering approval. A TESC plan has been prepared and submitted with the civil plans. The site will utilize Volume II of the 2014 DOE SMMWW for the erosion and sedimentation control design to reduce the discharge of sediment-laden runoff from the site. Clearing limits will be established prior to any earthwork on the project site. Perimeter protection will be provided by silt fencing along the downstream perimeter of the disturbed areas to limit the downstream transport of sediment to streams, wetlands and neighboring properties. Dust control, if required, will be provided by a water truck. A Certified Erosion and Sediment Control Lead inspector will be present onsite during earthwork activities. The inspector shall determine frequency of watering of the project site and will authorize and direct any additional erosion and sediment control measures as needed during all construction activities. The plan will be comprised of temporary measures (stabilized construction entrance, silt fence, interceptor swales, etc.) as well as permanent measures (detention ponds, hydroseeding, etc.). In general, construction activities will be sequenced such that the permanent detention pond will be constructed and used for temporary erosion and sedimentation control. Runoff from the site will sheet flow across cleared areas into temporary interceptor swales and into temporary pipes that discharge into the permanent detention pond or into the permanent conveyance system, when installed. Although the permanent detention pond will be used as the TESC pond for the project, the minimum TESC pond area, dewatering orifice diameter, and emergency spillway length are calculated below and compared to the proposed detention ponds to verify adequate TESC functionality. The TESC pond area was calculated for the project site using the 10-year storm event with the potential of work during the wet season (October 1 to April 30). The 10-year time step developed condition peak flow rate used for TESC pond area sizing is Q10 = 3.97 cfs TESC Pond Surface Area Calculations TESC Pond minimum surface area SA, is determined by the following equation: SA = 2080 sf/cfs * (Total Q10-developed) Where: SA = minimum TESC pond surface area (sf) Q10-developed = 10-year developed peak flow (3.97 cfs) SAmin = 8,258 sf The design bottom surface area of the proposed wetpond that will but used for TESC = 10,230 sf.
