MR #1 Stormwater Site Plan Narrative
PROJECT DESCRIPTION
The proposal is to remove the existing building on site, construct a four-story multi-use
building, and pave the parking lot. The main floor of the proposed building will be for
commercial use while the remaining floors will contain 2 one-bedroom units and 44 studio
units. A 2,500 sf courtyard is located on the third floor. Offsite improvements will include
diagonal parking, curb, gutter, and sidewalk along E. Division St. frontage, and improvements
to the alleys on both sides of Centennial Trail to create additional parking.
METHODOLOGY
Drainage calculations for the on-site area have been prepared using the 2019 Department of
Ecology Stormwater Management Manual for Western Washington (DOE SMMWW). The
site drainage design meets Low Impact Development (LID) standards by fully infiltrating all
stormwater runoff on-site. The infiltration trenches were sized using the 2012 Western
Washington Hydrology Model (WWHM). Given the total proposed new+replaced impervious
surface for the project is over 5,000 sf, the development will be required to meet minimum
requirements (MRs) 1-9 according to Volume I of the DOE SMMWW.
EXISTING CONDITIONS
The 0.39-acre site is located in the Old Town Business District 2 zone of the City of Arlington.
The site has an existing 1,520 sf building with asphalt for parking along the south and west of
the building. The remaining site is gravel that is used as a parking lot. With the existing
conditions of the site being more than 35% impervious, the project is characterized a
redevelopment.
A subsurface exploration was carried out by GeoTest on October 22, 2021 (see separate report).
There were six exploration test pits, the majority of which were advanced to a depth between
10 and 12 ft below ground surface. The test pit located in the area west of Centennial Trail was
advanced to a depth of 5 ft. Four test pits were located in the vicinity of the proposed building
and a test pit was located in the alley on either side of Centennial Trail. Historic fill was
encountered in TP-1,TP-2, and TP-4 between 2 and 8 ft deep over native Arlington gravel
member. TP-3, TP-5, and TP-6 encountered topsoil or surficial fill soils associated with the
parking lot for depths of 1 to 1.5 ft over native Arlington gravel member. Geotest provided an
infiltration rate of 8 in/hr for this Arlington gravel member. Refer to separate report for more
detail.
According to the NRCS (see Appendix A), the entire site is comprised of Everett very gravelly
sandy loam. This soil is described as being very deep, somewhat excessively drained soil found
on terraces and outwash plains. Permeability of the soil is rapid and available water capacity is
low. The top 6 inches is typically a dark brown gravelly sandy loam. The subsoil is about 12
inches thick and is dark brown very gravelly sandy loam. Below these layers the substratum is
brown very gravelly loam for about 5 inches and then dark brown extremely gravely sand to a
depth of 60 inches or more. It is categorized as hydrologic soils group A.

Project #22923
DEVELOPED CONDITIONS
The proposed redevelopment will remove the existing structure on-site as well as the existing
asphalt and gravel areas and replace them with a four-story building, new asphalt parking lot
areas, concrete walkways, and landscaped areas. The offsite improvements include diagonal
back-in parking, curb, gutter, and sidewalk along E. Division St. frontage, and improvements to
the alleys on both sides of Centennial Trail to create additional parking. The existing driveway
entrance on N. Olympic Avenue will be expanded north 10 feet to align with the proposed
drive aisle. The proposed areas are outlined in Table 2 and Table 3 below.

Given total proposed new+replaced impervious surface for the project is over 5,000 sf, the
development will be required to meet MRs 1-9 according to Volume I of the DOE SMMWW.
UPSTREAM ANALYSIS
Due to the developed surrounding properties, there is no upstream area that contributes flow to
the subject site.
DOWNSTREAM ANALYSIS
Currently the runoff from the site’s existing conditions flow towards the northwest of the
property. Runoff from the existing gravel parking lot flows onto E. Division St. at the
entrance east of the existing building where it enters the existing catch basin located on E.
Division St west of the property. The proposed development is not anticipated to have any
downstream impact as all the site’s stormwater runoff will be collected and fully infiltrated
Cascade Surveying & Engineering Inc. 8
Paisley Lofts
Project #22923
on-site. Fully infiltrating all runoff is anticipated to meet or lower the site’s runoff from its
predeveloped, native forested condition.
FLOW CONTROL
Flow control will be provided by fully infiltrating all runoff on-site through the use of
infiltration trenches. The infiltration trenches were sized for 100% infiltration of 8% of the
2-year peak flow through the full 50-year peak flow using the 2012 Western Washington
Hydrology Model (WWHM). Specifics about the proposed flow control trenches are further
discussed in MR 7.
RUNOFF TREATMENT
The infiltration trenches have 1.5’ of soil amended to have a cation exchange capacity
(CEC) of 5 milliequivalents CEC/100g of dry soil or better. This will provide runoff
treatment for the pollution generating hard surfaces. The trench was sized for 100%
infiltration so all stormwater runoff will pass through the amended soils. Specifics about the
proposed water quality trench are further discussed in MR 6.
MR #2 Stormwater Pollution Prevention Plan Narrative
See Separate Report.
MR #3 Water Pollution Source Control
No known pollution generating activities described in volume IV, chapters 3 and 4 of the Snohomish
County Drainage Manual will be performed on-site during construction or are proposed for the
developed site following construction. Any sources of pollution that may result from the construction
activity will be controlled according to SWPPP Element #9, Control Pollutants.
MR #4 Preservation of Natural Drainage Patterns
The natural drainage patterns identified in the drainage report under MR #1 and on the stormwater site
plan will be maintained during construction and post development. The natural drainage sheetflows
offsite to the northwest of the property and enters the existing catch basin on E. Division St. west of
the property. The site is designed to fully infiltrate runoff and will reduce the previously unmitigated
discharge downstream.
MR #5 On-Site Stormwater Management
The proposed development will meet Low Impact Development (LID) and flow control requirements
per Sections I-2.5.5 and I-2.5.7 of the 2019 Stormwater Management Manual for Western Washington
(SMMWW). The post-developed conditions will have flow rates meeting 8% of the 2-year peak flow
through the full 50-year peak flow.

Project #22923
Three infiltration trenches will be located within the project site:
1. Trench A is located beneath the parking in the alley to mitigate runoff from onsite impervious
areas and the alley east of Centennial Trail.
2. Trench B is located in the E. Division St. frontage to mitigate runoff from E. Division St.
frontage improvements.
3. Trench C is located under the proposed parking in the alley west of Centennial Trail to
mitigate for the proposed parking west of Centennial Trail.
The infiltration rate of 8 in/hr used in the calculations was measured by Geotest. All proposed
impervious surfaces will be conveyed to one of the above trenches. The size of each trench can be seen
in WWHM (Appendix B) and the construction plans.
BMP T5.13 Post Construction Soil Quality and Depth:
Post Construction Soil Quality and Depth will be used on site to recondition those areas that were
impacted due to construction activities. Those areas to be reconditioned have been identified on the
construction plans as landscape areas. The existing on-site topsoil will be tilled, and compost added to
the soil prior to final seeding. The intent of this BMP is to restore the pre-developed drainage
characteristics of the soil.
MR #6 Runoff Treatment
Runoff treatment for the proposed parking lot and driveway areas will be provided through water
quality infiltration trenches. These trenches will have 1.5’ of soil amended to have a cation exchange
capacity (CEC) of 5 milliequivalents CEC/100g of dry soil or better.
The water quality trenches are sized by achieving 100% infiltration using WWHM. Details on the
proposed trench are outlined in the WWHM report provided in Appendix B and the construction plans.
MR #7 Flow Control
Flow control will be provided for the impervious areas onsite through the use of infiltration trenches.
These infiltration trenches are designed using WWHM to detain all runoff from 8% of the 2-year storm
through the full 50-year storm until it fully infiltrates.
Details on the proposed trenches are outlined in the WWHM report provided in Appendix B.
MR #8 Wetland Protection
There are no wetlands on site or within the area of disturbance.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/
portal/nrcs/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?
cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous
areas in a specific area. They include a description of the soils and miscellaneous
areas and their location on the landscape and tables that show soil properties and
limitations affecting various uses. Soil scientists observed the steepness, length,
and shape of the slopes; the general pattern of drainage; the kinds of crops and
native plants; and the kinds of bedrock. They observed and described many soil
profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The
profile extends from the surface down into the unconsolidated material in which the
soil formed or from the surface down to bedrock. The unconsolidated material is
devoid of roots and other living organisms and has not been changed by other
biological activity.
Currently, soils are mapped according to the boundaries of major land resource
areas (MLRAs). MLRAs are geographically associated land resource units that
share common characteristics related to physiography, geology, climate, water
resources, soils, biological resources, and land uses (USDA, 2006). Soil survey
areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that
is related to the geology, landforms, relief, climate, and natural vegetation of the
area. Each kind of soil and miscellaneous area is associated with a particular kind
of landform or with a segment of the landform. By observing the soils and
miscellaneous areas in the survey area and relating their position to specific
segments of the landform, a soil scientist develops a concept, or model, of how they
were formed. Thus, during mapping, this model enables the soil scientist to predict
with a considerable degree of accuracy the kind of soil or miscellaneous area at a
specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented
by an understanding of the soil-vegetation-landscape relationship, are sufficient to
verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them
to identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character
of soil properties and the arrangement of horizons within the profile. After the soil
5
Custom Soil Resource Report
scientists classified and named the soils in the survey area, they compared the
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that
have similar use and management requirements. Each map unit is defined by a
unique combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components
of the map unit. The presence of minor components in a map unit in no way
diminishes the usefulness or accuracy of the data. The delineation of such
landforms and landform segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, onsite
investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape,
and experience of the soil scientist. Observations are made to test and refine the
soil-landscape model and predictions and to verify the classification of the soils at
specific locations. Once the soil-landscape model is refined, a significantly smaller
number of measurements of individual soil properties are made and recorded.
These measurements may include field measurements, such as those for color,
depth to bedrock, and texture, and laboratory measurements, such as those for
content of sand, silt, clay, salt, and other components. Properties of each soil
typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists
interpret the data from these analyses and tests as well as the field-observed
characteristics and the soil properties to determine the expected behavior of the
soils under different uses. Interpretations for all of the soils are field tested through
observation of the soils in different uses and under different levels of management.
Some interpretations are modified to fit local conditions, and some new
interpretations are developed to meet local needs. Data are assembled from other
sources, such as research information, production records, and field experience of
specialists. For example, data on crop yields under defined levels of management
are assembled from farm records and from field or plot experiments on the same
kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on
such variables as climate and biological activity. Soil conditions are predictable over
long periods of time, but they are not predictable from year to year. For example,
soil scientists can predict with a fairly high degree of accuracy that a given soil will
have a high water table within certain depths in most years, but they cannot predict
that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings,
fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
areas.

Custom Soil Resource Report
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.

INTRODUCTION
Background
All residential, commercial, and industrial developments have some form of stormwater
drainage facilities. Stormwater facilities generally drain to roadside ditches, underground storm
pipe systems, streams, lakes, or to groundwater from infiltration facilities. Stormwater facilities
generally consist of pipes, catch basins, swales, ditches, ponds, oil/water separators,
underground infiltration trenches, and any other structure that collects, conveys, controls, and
treats stormwater.
Stormwater facilities are either privately owned or publicly owned. Private stormwater facility
owners consist of individual residential property owners, a home owners’ association,
commercial and industrial land owners. Privately owned stormwater facilities are generally
installed on private property within the bounds of the private land, in a separate tract, or in an
easement on land owned by others.
Publicly owned stormwater facilities are usually owned and operated by a city, county, state, or
federal entities. In either case, the owner of the system is responsible for operating and
maintaining all elements of the facility.
Purpose
The objective of this manual is to ensure that stormwater control facilities are adequately
maintained and operated properly.
Storm system maintenance is necessary to protect streams, lakes, wetlands, and groundwater.
Proper maintenance assures that storm systems operate as they were designed, and that they
are cleaned of pollutants that they trap, such as sediment and oils, so that the storm system is
not overwhelmed and becomes a pollutant source.
Stormwater System Inspection Schedule
The drainage system should be monitored periodically. For the first year after completion of
construction, the system should be monitored after every large storm event (> 1-in in 24-hrs),
and, during the period Oct. 1- Mar. 31 inspections should be conducted monthly. From April 1-
Sept. 30, the facility should be monitored on a quarterly basis. Once the performance
characteristics of the facility have been verified, the monitoring schedule can be reduced to an
annual basis unless the performance data indicate that a more frequent schedule is required.
(CATCH BASIN)
Yard Drain & Cleanout
What is a Yard Drain?
A Yard Drain is similar to a Type 1 Catch Basin but smaller (most are 12 to 18 inches in diameter).
ï‚· Currently, the most frequently used type of yard drain is a high density polyethylene (HDPE) pipe:
o set vertically on end,
o with the bell end up fitted with a grate, and
o the bottom end resting on washed drain rock.
ï‚· There are older versions which are made of either polyvinylchloride (PVC) or Concrete Pipe.
How does a Yard Drain work?
Yard Drain systems usually consist of several yard drains and 6â€-8†diameter HDPE pipe between them. They are
designed for use in private residential or commercial property and not for use in public or private streets and
roads.
ï‚· They function as an intermediary stormwater conveyance system that connects roof and building
foundation footing drains (4â€-6†diameter HDPE pipe) to the main stormwater conveyance system of:
o Type 1 or 2 Catch Basins, and
o 12†and larger diameter HDPE pipe.
ï‚· Typically, in residential subdivisions these systems can be located along lot lines.
ï‚· Yard Drains also have commercial property applications, often being installed to connect building roof
and footing drains To the parking area and driveway drainage systems.
NOTE: If Yard Drains are not visible, it is possible that Cleanouts were installed as a substitute. This is generally
the case when the depth from the top of the Yard Drain grate to what would be the top of the washed drain
rock exceeds 42â€. (See drawings below.)
Common maintenance needs
The most common tool for cleaning Yard Drains or Cleanouts is a yard hose. Cleaning by a vactor truck with its
very high pressure and volume washing and vacuum system can destroy both the older Yard Drains or Cleanouts
and pipe. It is better to use a low pressure washing system and scoop out by hand any mud and debris collecting
in the Yard Drains or Cleanouts.

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
To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of
construction will be clearly marked before land-disturbing activities begin. Trees that are to be
preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the
field and on the plans. In general, natural vegetation and native topsoil shall be retained in an
undisturbed state to the maximum extent possible. The BMPs relevant to marking the clearing
limits that will be applied for this project include:
o Preserving Natural Vegetation (BMP C101)
o High Visibility Plastic or Metal Fence (BMP C103)
BMP C101: Clearing limits will be marked both on the plans and in the field, where natural
vegetation is to be protected.
BMP C103: High visibility plastic fence will be used to delineate clearing limits and areas of
vegetation to be protected.
Alternate BMPs for marking clearing limits are included in Appendix C as a quick reference tool
for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or
inappropriate during construction, the Certified Erosion and Sediment Control Lead will
promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix
C after the first sign that existing BMPs are ineffective or failing.
2.1.2 Element 2: Establish Construction Access
Construction access or activities occurring on unpaved areas shall be minimized, yet where
necessary, access points shall be stabilized to minimize the tracking of sediment onto public
roads, and wheel washing, street sweeping, and street cleaning shall be employed to prevent
sediment from entering state waters. All wash wastewater shall be controlled on site. The
specific BMPs related to establishing construction access that will be used on this project
include:
o Stabilized Construction Entrance (BMP C105)
BMP C105: A stabilized construction entrance will be located at the entrance to the site.
P a g e | 6
Alternate construction access BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction, the Certified Erosion and Sediment Control Lead will promptly initiate the
implementation of one or more of the alternative BMPs listed in Appendix C after the first sign
that existing BMPs are ineffective or failing.
2.1.3 Element 3: Control Flow Rates
In order to protect the properties and waterways downstream of the project site, stormwater
discharges from the site will be controlled if increased. The specific BMPs for flow control that
is being used on this project include:
o Silt Fence (BMP C233)
Alternate flow control BMPs are included in Appendix C as a quick reference tool for the onsite
inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during
construction, the Certified Erosion and Sediment Control Lead will promptly initiate the
implementation of one or more of the alternative BMPs listed in Appendix C after the first sign
that existing BMPs are ineffective or failing.
In general, discharge rates of stormwater from the site will be controlled where increases in
impervious area or soil compaction during construction could lead to downstream erosion, or
where necessary to meet local agency stormwater discharge requirements (e.g. discharge to
combined sewer systems).
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
2.1.4 Element 4: Install Sediment Controls
All stormwater runoff from disturbed areas shall pass through an appropriate sediment removal
BMP before leaving the construction site or prior to being discharged to an infiltration facility.
The specific BMPs to be used for controlling sediment on this project include:
o Silt Fence (BMP C233)
Alternate sediment control BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction, the Certified Erosion and Sediment Control Lead will promptly initiate the
P a g e | 7
implementation of one or more of the alternative BMPs listed in Appendix C after the first sign
that existing BMPs are ineffective or failing.
In addition, sediment will be removed from paved areas in and adjacent to construction work
areas manually or using mechanical sweepers, as needed, to minimize tracking of sediments on
vehicle tires away from the site and to minimize washoff of sediments from adjacent streets in
runoff.
Whenever possible, sediment laden water shall be discharged into onsite, relatively level,
vegetated areas (BMP C240 paragraph 5, page 4-102).
2.1.5 Element 5: Stabilize Soils
Exposed and unworked soils shall be stabilized with the application of effective BMPs to prevent
erosion throughout the life of the project. The specific BMPs for soil stabilization that shall be
used on this project include:
o Preserve Natural Vegetation (BMP C101)
o Temporary and Permanent Seeding (BMP C120)
o Mulching (BMP C121)
o Plastic Covering (BMP C123)
o Topsoiling/Composting (BMP C125)
Alternate soil stabilization BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction, the Certified Erosion and Sediment Control Lead will promptly initiate the
implementation of one or more of the alternative BMPs listed in Appendix C after the first sign
that existing BMPs are ineffective or failing.
The project site is located west of the Cascade Mountain Crest. 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.

Responsible Staff: Scott Wammack
2.1.6 Element 6: Protect Slopes
All cut and fill slopes will be designed, constructed, and protected in a manner than minimizes
erosion. The following specific BMPs will be used to protect slopes for this project:
o Temporary and Permanent Seeding (BMP C120)
Alternate slope protection BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction, the Certified Erosion and Sediment Control Lead will promptly initiate the
implementation of one or more of the alternative BMPs listed in Appendix C after the first sign
that existing BMPs are ineffective or failing.
Will steep slopes be present at the site during construction?
Yes No
2.1.7 Element 7: Protect Drain Inlets
All storm drain inlets and culverts made operable during construction shall be protected to
prevent unfiltered or untreated water from entering the drainage conveyance system. 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. Storm Drain Inlet Protection (BMP
C220) will be implemented for all drainage inlets and culverts that could potentially be impacted
by sediment-laden runoff on and near the project site. The following inlet protection measures
will be applied on this project:
o Storm Drain Inlet Protection (BMP C220).
P a g e | 9
If the BMP options listed above are deemed ineffective or inappropriate during construction, the
Certified Erosion and Sediment Control Lead shall implement one or more of the alternative
BMP inlet protection options listed in Appendix C.
2.1.8 Element 8: Stabilize Channels and Outlets
There are no outlets proposed on site.
2.1.9 Element 9: Control Pollutants
The following pollutants are anticipated to be present on-site:
Table 2 – Pollutants
Pollutant (List pollutants and source, if applicable)
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 stormwater. 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.
The facility does not require a Spill Prevention, Control, and Countermeasure (SPCC) Plan under
the Federal regulations of the Clean Water Act (CWA).
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

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
There will be no dewatering during the duration of the project.
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.
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.
P a g e | 11
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.
P a g e | 12
2.1.12 Element 12: Manage the Project
The project will be managed based on the following principles:
• Projects will be phased to the maximum extent practicable and seasonal work limitations
will be taken into account.
• 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.
• 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.

documentation of the inspection and sampling findings in a site log book. A site log book will be
maintained for all on-site construction activities and will include:
• A record of the implementation of the SWPPP and other permit requirements
• Site inspections
• Stormwater sampling data
A Construction Stormwater Site Inspection Form File can be found under Appendix D.
The site log book must be maintained on-site within reasonable access to the site and be made
available upon request to Ecology or the local jurisdiction.
Numeric effluent limits may be required for certain discharges to 303(d) listed waterbodies. See
CSWGP Special Condition S8 and Section 5 of this template.

I’ll add it under the PW-Admin review even though it was last completed in May, if that’s the proper
location. Just wanted to make sure it didn’t get missed if PW-Admin was closed out.
Thanks!

Subject: Paisley Lofts ADA Ramp
Hi Raelynn,
In the process of measuring the ADA ramps on Division for next year’s overlay project we found that
the ADA ramp on the SW corner of Division and Olympic was not up to current standards, despite it
appearing so. The ramp running slope exceeds the required minimum slope.
I’d like to include in the next batch of review comments that the ramp will need to be replaced and
upgraded to current standards as part of their frontage improvements. This will also avoid us having
to impact their new frontage with construction next year as we would have no choice but to replace
it.
Thank you,
Ryan
