Executive Summary
Soundview Consultants LLC (SVC) is assisting MJS Investors (Applicant) with a Wetland and Fish
and Wildlife Habitat Assessment Report for the residential development of a 32.28-acre site located
at 8014, 8228, 8210,and 8326 172nd Street Northeast within the City of Arlington,Washington. The
subject property consists of five parcels situated in the Northeast 1/4, of Section 26, Township 31
North, Range 5 East, (Snohomish County Tax Parcel Numbers 31052500200600, 31052600100100,
31052600100200, 31052600102200, 31052600102300).
SVC investigated the subject property for the presence of potentially-regulated wetlands,waterbodies,
fish and wildlife habitat,and/or priority species in December of 2022 and April of 2024. Using current
methodology,the site assessments identified four potentially-regulated wetlands onsite (Wetlands A—
D) and one stream (Stream Z) on the subject property. Additionally, one offsite wetland (Wetland 1)
was identified offsite to the west of the subject property. Wetlands A and D are classified as a Category
IV wetlands per Arlington Municipal Code (AMC) 20.93.800 and are subject to a standard 40-foot
buffer regardless of habitat score per AMC 20.93.830 Table 20.93-4 with the required use of
minimization measures outlined in AMC Table 20.93-5. Wetlands B, C, and 1 are Category III
wetlands per AMC 20.93.800 with moderate habitat scores of(6 or 7) and are subject to a standard
110-foot buffer per AMC 20.93.830 Table 20.93-4 with the required use of minimization measures
outlined in AMC Table 20.93-5. Stream Z is a seasonal, non-fish bearing stream and is therefore
considered a Type Ns water per AMC 20.93.700 and is subject to a standard 50-foot buffer per AMC
20.93.730 Table 20.93-3. In addition, a 15-foot structure setback is required at the edge of wetland
and stream buffers per AMC 20.93.340. No other potentially-regulated wetlands, waterbodies, fish
and wildlife habitat, and/or priority species were identified within 300 feet of the subject property.
SVC has met onsite multiple times with Todd Gray who is the Environmental Protection Ecologist
for the Tulalip Tribe, to assess the stream typing of Stream Z. SVC and Todd Gray also assessed the
culvert and onsite stream conditions on parcel 31052600100800. Todd Gray is in agreeance that
Stream Z is a Type Ns stream upgradient of the large approximately 260-foot long culvert located on
parcel 31052600100800. Additionally, Todd Gray and other biologists with the Tulalip Tribe have
determined that the headwaters of Edgecomb Creek are located to the west of the subject property
and are located on parcels 31052600101400, 31052600101500, 31052600100300, and
31052600100800. The true headwaters of Edgecomb Creek on parcels 31052600101400,
31052600101500, 31052600100300, and 31052600100800, are not identified by DNR Stream typing
or by WDFW and NWIFC-SWIFD. However, the headwaters of Edgecomb Creek are located in a
large ravine that is easily depictable on Lidar Hillshade.
The Applicant is assessing the potential for residential development on the subject property. All
necessary code analytics and mitigation strategy will be outlined in a Conceptual Mitigation Plan under
a separate cover.
The table below summarizes the identified critical areas on the subject property and their regulatory

Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
Chapter 3. Methods
SVC investigated, assessed, and delineated any potentially-regulated wetlands,waterbodies, and other
fish and wildlife habitat on and within 300 feet of the subject property in December of 2022 and April
of 2024. All determinations were made using observable vegetation, hydrology, and soils in
conjunction with data from the U.S. Geological Survey (USGS) topographic maps, the Natural
Resource Conservation Service (MRCS) soil survey,U.S. Fish and Wildlife Service (USFWS) National
Wetland Inventory (NWI),Washington Department of Fish and Wildlife (WDFW) Priority Habitats
and Species (PHS) and SWIFD mapping tools,Department of Natural Resources (DNR)water typing
system, Snohomish County's public geographic information systems (GIS), local precipitation data,
and various orthophotographic resources.
Wetland boundaries were determined in accordance with Arlington Municipal Code (AMC)20.93.810,
and as outlined in the U.S. Army Corps of Engineers' (USACE) Wletlands Delineation Manual
(Environmental Laboratory, 1987) as modified according to the guidelines established in the Regional
Supplement to the Corps of Engineers Wletland Delineation Manual. Wlestern Mountains, Valleys, and Coast Region,
(Version 2.0) (USACE, 2010) and Field Indicators of Hydric Soils in the United States (USDA, 2018).
Qualified wetland scientists marked boundaries of the onsite wetlands with orange surveyor's flagging
labeled alpha-numerically and tied to 3-foot lath or vegetation along the wetland boundary. Pink
surveyor'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 on the subject property(DP-
1 to DP-32). Additional tests pits were excavated at regular intervals inside and outside of the wetland
boundaries to further confirm the delineations.
SVC classified all wetlands 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 Wlashington State
Wletlands Rating System for Wlestern Wlashington-2014 Updated Version 2.0 (Hruby and Yahnke 2023) and
the guidelines and definitions established under AMC 20.93.800.
Ordinary high water (OHW) mark determinations were made using Washington State Department of
Ecology's (WSDOE's)methodology,as detailed in Determining the Ordinary High WaterMark for Shoreline
Management Act Compliance in Wlashington State(Anderson et al.,2016),and the definitions established in
the Revised Code of Washington (RCW) 90.58.030(2)(b) and Washington Administrative Code
(WAC) 173-22-030(11). To mark the centerline or banks of potentially-regulated streams and
shorelines, blue surveyor's flagging was alpha-numerically labeled and tied to vegetation. Offsite
waters were observed and OHW boundaries estimated based on topography and aerial imagery.
Streams and surface water features were classified using the DNR water typing system as outlined in
WAC 222-16-030 and the guidelines established in AMC 20.93.700.
The fish and wildlife habitat assessment was conducted during the same site visits by 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 (e.g. nesting, foraging, and migration/movement). Special attention
was given to assessing the presence of wildlife habitat areas outlined under AMC 20.93.400.

Chapter 4. Background
4.1 Landscape Setting
The subject property is located within a rural residential setting within the City of Arlington and is
partially developed with four single-family residences, associated infrastructure,gravel driveways, and
garages. Much of the site consists of open fields, lawn, and small pockets of deciduous trees and
shrubs,with a larger forested area located on the southeast area of the subject property. The subject
property abuts 172nd Street Northeast to the north, a single-family residence and undeveloped land to
the east, undeveloped forested land and chicken farm facilities to the south, and single-family
residences on large lots to the west. Topography on the site generally slopes from southeast to
northwest with elevations ranging from approximately 408 feet above mean sea level (amsl) to 360
feet amsl (Appendix B1). The subject property is within the Snohomish River Watershed (Water
Resources Inventory Area 7).

4.2 Soils
The NRCS soil survey identifies one soil series on the site:Tokul gravelly medial loam, 0 to 8 percent
slopes. A NRCS soil survey map is provided in Appendix B2. A description of the soil profile is
below.
Tokul gravelly medial loam, 0 to 8 percent slopes (72)
2419.0002-Lindsay Annexation 4 Soundview Consultants LLC
Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
According to the NRCS survey,Tokul gravelly medial loam,0 to 8 percent slopes is a moderately well
drained soil formed in glacial till and volcanic ash. In a typical profile, the surface layer is
approximately 4 inches thick and is a dark brown gravelly loam. From 4 to 22 inches the subsoil is a
brown, strong brown and dark yellowish-brown gravelly loam. From 22 to 31 inches the soil is light
olive brown gravelly fine sandy loam. A hard pan is present at a depth of approximately 31 inches.
Water capacity is moderate and permeability is moderate above the hard pan and very slow through
it.Tokul gravelly medial loam, 0 to 8 percent slopes is listed as a non-hydric soil (MRCS,N.d.),but as
much as 5 percent of areas mapped as Tokul gravelly medial loam, 0 to 8 percent slopes may contain
hydric inclusions of McKenna and Norma loams.
4.3 Critical Area Inventories
The DNR Stream Typing map (Appendix B3), WDFW and NWIFC-SWIFD map (Appendix B4),
and the Snohomish County Streams and Wetlands Inventory map (Appendix B5) identify a stream
running parallel to the subject property from the southeast to the northwest before briefly coming
onto the southwestern most portion of the property. The onsite portion of the stream is identified as
Type N (non-fish bearing) by DNR Stream Typing and as a Type F (fish bearing) stream by WDFW
and NWIFC-SWIFD. The stream is indicated to continue offsite to the northwest and eventually
transitions to Type F per DNR Stream Typing and WDFW and NWIFC-SWIFD. The USFWS NWI
map (Appendix 136) does not identify any wetlands or streams onsite or within 300 feet of the subject
property. The WDFW PHS map (Appendix B7) identifies a linear wetland or stream feature located
approximately 210 feet offsite to the east of the subject property. The Snohomish County Stream and
Wetland Inventory map identifies an offsite wetland located on parcel 31052600101700 approximately
45 feet offsite to the west of the subject property. No other wetlands or streams are mapped onsite
or within 300 feet of the subject property.
4.4 Priority Habitats and Species
The WDFW PHS map identifies the listed occurrence and migration of Dolly Varden/bull trout and
the occurrence of coho salmon in Stream Z. The WDFW and NWIFC SWIFD map lists the
documented spawning of coho salmon, the presumed presence of Dolly Varden/bull trout; and
gradient accessible reaches for chinook salmon,pink salmon, and winter steelhead trout in Stream Z.
No other wetlands, streams, or priority habitats or species are documented on or within 300 feet of
the subject property.
4.5 Precipitation
Precipitation data was obtained from the National Oceanic and Atmospheric Administration(NOAA)
weather station at Everett Paine Field Airport located in Snohomish County in order to acquire
precipitation values during and preceding the field investigations. A summary of data collected is
provided in Table 1.

Notes:
1. Precipitation level provided in inches.Data obtained from the NOAA(http://w2.weather.gov/climate/xmacis.php?wfo=sew)for Everett Paine
Field Airport.
2. Year-to-date precipitation is the total for the water year from October 1st to the 2022 and 2024 onsite dates.
Precipitation levels during the December 2022 site visit were below the statistical normal range (70 to
130 percent of normal) for the prior 30 days (43 percent of normal) and were within the historical
normal range for the water year (76 percent of normal). Precipitation levels during the April 2024 site
visits were within the statistical normal range for the 2024 water year(81 to 82 percent of normal) and
were below normal(40 to 45 percent of normal) for the prior 30 days. This precipitation data suggests
that hydrologic conditions may have been drier than usual at the time of the site investigations;
however hydrological conditions were still likely representative of normal conditions, as 0.70-inches
of precipitation was recorded during the week leading up to the site investigation and 0.44-inches of
precipitation was recorded on the first day of the wetland delineation (April 2"d). Such conditions
were considered in making professional wetland determinations.

Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
Chapter 5. Results
The site investigations in December of 2022 and April of 2024 identified four potentially-regulated
wetlands (Wetlands A - D) and one stream (Stream Z) on the subject property. Additionally, one
potentially regulated offsite wetland (Wetland 1) was identified offsite to the west within 300 feet of
the subject property. No other potentially-regulated wetlands,waterbodies, fish and wildlife habitat,
or priority species were identified on or within 300 feet of the subject property.
5.1 Upland Characterization
Vegetation on the majority of the site is dominated by grasses and forbs including non-native invasive
reed canarygrass (Phalaris arundinacea),creeping buttercup (Ranunculus repens),perennial ryegrass (Lolium
perenne), common velvetgrass (Holcus lanatus), and common dandelion (Taraxacum ofcinale). Forested
cover is present on the southeastern portion of the site and includes western red cedar (Thuja plicata),
western hemlock (Tsuga heterophylla),black cottonwood (Populus balsamifera),and red alder (Alnus rubra)
with an understory of non-native invasive Himalayan blackberry (Bubus armeniacus), salmonberry
(Aubus spectabalis),western sword fern (Polystichum munitum), and trailing blackberry (Aubus ursinus).
5.2 Wetlands
Four wetlands (Wetland A- D) were identified and delineated on the subject property. One wetland
(Wetland 1) was also identified offsite to the west within 300 feet of the subject property. The
delineated wetlands contained indicators of wetland hydrology, hydric soils (presumed for offsite
wetlands), and a predominance of hydrophytic vegetation according to current wetland delineation
methodology. Maps depicting the location and size of the wetlands are presented in Appendix A.
Data forms are provided in Appendix C, wetland rating forms are provided in Appendix D, and
wetland rating maps are provided in Appendix E. Table 2 below summarizes the wetlands identified

Wetland A
Wetland A is approximately 22,644 square feet(0.52 acre)in size and is located on the southern portion
of the subject property. Hydrology for Wetland A is provided by a seasonally-high water table,direct
precipitation and surface runoff from adjacent uplands. Wetland vegetation is dominated by velvet
grass, common rush (Juncus ffusus), birdsfoot trefoil (Lotus corniculatus), and non-native invasive reed
canarygrass. The buffer surrounding Wetland A consists of fields that are degraded by previous
grading and non-native invasive reed canary grass. Hydric soil indicators All (Depleted below dark
surface) and F3 (Depleted Matrix) were observed. Wetland boundaries were determined by a
transition of topography and wetland hydrology. Wetland A is a Palustrine Emergent and Seasonally
Saturated wetland (PEMB). Table 3 provides a summary of Wetland A.

Wetland 1
Wetland 1 is located approximately 80 feet offsite to the west of the subject property and is associated
with Stream Z. Hydrology for Wetland 1 is provided primarily by a seasonally high groundwater table,
direct precipitation,surface sheet flow from surrounding uplands,and overbank flooding from Stream
Z. Due to its offsite location,no formal data was collected in Wetland 1 and hydric soils and wetland
hydrology are presumed. The wetland boundary was estimated based on visual observations during
the site investigations, aerial imagery, and LiDAR imagery. Wetland 1 is a Palustrine Emergent,
Occasionally Flooded,and Seasonally Flooded wetland(PENIAC). As it is located offsite,no summary
table is provided.
5.3 Streams
(Stream Z)
Stream Z originates offsite to the southwest of the subject property and the onsite potion is located
on the northwestern edge of the property before continuing offsite to the northwest via a culvert
beneath 79'Avenue Northeast. Stream Z flows from south to northwest. Stream Z appears to be
artificially channelized through the subject property, and the onsite portion was flowing throughout
the onsite reach during the April 2024 site investigations. The channel width varies from
approximately 3 to 7 feet throughout the site with an average width of approximately 5 feet. Stream
Z originates approximately 160 feet southwest of the subject property. The creek exits the subject
property via a 2-foot culvert and continues to flow northwest from the subject property then
southwest before meandering to the southeast. Stream Z eventually outlets into Middle Fork Quilceda
Creek approximately 2.25 miles to the southwest of the subject property. Middle Fork Quilceda Creek
then outlets into the mainstem of Quilceda Creek,which outlets directly to Puget Sound. The onsite
stream buffer area is degraded by seasonally mowed fields.
SVC has met onsite multiple times with Todd Gray who is the Environmental Protection Ecologist
for the Tulalip Tribe, to assess the stream typing of Stream Z. SVC and Todd Gray also assessed the
culvert and onsite stream conditions on parcel 31052600100800. Todd Gray is in agreeance that
Stream Z is a Type Ns stream upgradient of the large approximately 260-foot long culvert located on
parcel 31052600100800. Additionally, Todd Gray and other biologists with the Tulalip Tribe have
determined that the headwaters of Edgecomb Creek are located to the west of the subject property
and are located on parcels 31052600101400, 31052600101500, 31052600100300, and
31052600100800. The true headwaters of Edgecomb Creek on parcels 31052600101400,
31052600101500, 31052600100300, and 31052600100800, are not identified by DNR Stream typing
or by WDFW and NWIFC-SWIFD. However, the headwaters of Edgecomb Creek are located in a
large ravine that is easily depictable on Lidar Hillshade.
The actual consistently defined stream channel of Stream Z appears to begin at the downstream end
of a culvert system on parcel 31052600102000. During the reconnaissance investigation in December
of 2022,SVC staff had access to parcel 31052600102000, as the Applicant was assessing feasibility on
parcel 31052600102000. During the reconnaissance investigation SVC staff observed no defined
channel to the south of the southern culvert,while a defined channel was observed immediately north
of the culvert system on parcel 31052600102000.
2419.0002-Lindsay Annexation 14 Soundview Consultants LLC
Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
DNR Stream Typing and WDFW and NWIFC-SWIFD identify Stream Z originating near the
northern culvert described above on parcel 31052600102000. DNR Stream Typing classifies the
portions of Stream Z near or on the subject property as a Type N (non-fish-bearing stream). WDFW
and NWIFC-SWIFD identifies the creek as gradient accessible for pink, chinook, and steelhead; the
presumed presence of bull trout; and the documented spawning of coho salmon. However, there is
a culvert fish passage barrier beneath a large gravel staging area for machinery and access on
Snohomish County parcel 31052600100800, as DNR Stream Typing displays a break from a Type F
(fish bearing) stream to a Type N stream on parcel 31052600100800. No fish were observed within
the stream at the time of the site investigation. Due to the heavily degraded conditions of the stream
onsite and offsite to the west and south, with the stream channel being choked full of non-native
invasive reed canarygrass, shallow flows, and potential downstream fish passage barrier on parcel
31052600100800, the onsite portion Stream Z is considered a Type N (non-fish-bearing) stream per
AMC 20.93.700. A summary of Stream Z is provided in Table 7 below.

b seasonally mowed fields.
5.4 Non-Regulated Ditches
A series of manmade,artificially constructed drainage ditches were observed on the southeastern area
of the subject property. The ditch systems located within or adjacent to Wetlands A, B, and C flow
from north to south and exit the subject property at the southwest corner of the subject property.
The ditches continue offsite to the southwest and drain into Stream Z northwest of their exit point.
These ditches are approximately 4 to 6 feet wide and feature linear,vertical-cut channels indicative of
manmade conditions. The linear nature of the channels,steep vertical banks,and berms built up along
the sides of the some of the ditches, indicate that these were likely constructed to manage surface
runoff.
A second series of manmade, artificially constructed drainage ditches were observed on the northern
area of the subject property. The ditches flow from south to north. The ditches on the northern half
of the site are conveyed offsite to the north into a roadside stormwater ditch. The identified ditches
are approximately 2 to 4 feet wide and feature linear, vertical-cut channels indicative of manmade
conditions, and lack a defined bed or bank. The linear nature of the channels, steep vertical banks,
and berms built up along the sides of the some of the ditches,indicate that these were constructed to
manage surface runoff.
Per AMC 20.93.100, "streams do not include irrigation ditches, canals, stormwater runoff devices or other entirely
artificial watercourses unless they are used to convey any stream naturally occurring prior to construction",and"wetlands
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, or those wetlands created after July 1, 1990, that were unintentionally created as a result of
the construction of a road, street, or highway'. As such, the drainage ditches onsite are not anticipated to be
considered streams or wetlands and should not be subject critical area boundaries and buffers.
5.5 Fish and Wildlife Habitat Conservation Areas
Per AMC 20.93.400, fish and wildlife habitat conservation areas consist of the following:
A. Lands containing priority habitats and species, including plant andl or animal species listed on federal or state
threatened or endangered species lists;
According to the USFWS IPaC mapping database, North American wolverine (Gulo gulo
luscus), marbled murrelet (Brachyramphus marmoratus),yellow-billed cuckoo (CocgZus americanus),
Northwestern pond turtle (Actinemys marmorata), and bull trout (Salvelinus confuentus) have the
potential to occur within 300 feet of the subject property. Additionally,WDFW PHS identifies
the occurrence of coho salmon (Oncorhynchus kisutch) and bull trout within Edgecomb Creek.
North American wolverines (Gulo gulo luscus) commonly occur in boreal forests and tundra
ecosystems and in Washington they occupy alpine and subalpine forests within the North
Cascades National Park and the wilderness areas of the Okanogan-Wenatchee National Forest
2419.0002-Lindsay Annexation 16 Soundview Consultants LLC
Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
where heavy snowpack persists well into the spring months (WDFW, n.d.). Population
estimates vary between 20 to 35 individuals residing in Washington state. Wolverines will
travel hundreds of miles when hunting and will consume a wide variety of foods including
insects,berries,marmots,ground squirrels,snowshoe hares and other small mammals but they
are predominantly scavengers of carrion of large animals. No boreal forests or tundra
ecosystems, marine waters, or riparian habitats are present within the vicinity of the subject
property; as such North American wolverine are not present onsite or within 300 feet of the
subject property.
Marbled murrelet that occur in the state of Washington are year-round residents on coastal
waters and 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. Potential suitable habitat typically consists of tree stands
5 or more acres in size composed of 60% or more conifer cover with minimum 15-inch
diameter at breast height (DBH) with nesting platform trees. Nesting platform trees include
"platform branches" that are a relatively flat surface at least four inches wide, at least 33 feet
high in a coniferous tree,with cover from the live crown of the same tree or an adjacent tree
(WSDOT, 2014). The nearest sightings of marbled murrelet occurred in 2023 approximately
8 miles to the east of the subject property in the vicinity of Twin Lakes (eBird, n.d.). Habitat
requirements for this species are potentially present on the southeast forested area of the site;
however,due to the surrounding fragmented landscape,adjacent roadways,residential homes,
and commercial chicken farm, the habitat conditions onsite and surrounding the subject
property are not likely conducive for marbled murrelet nesting and marbled murrelet are likely
not present on or within 300 feet of the subject property.
Yellow-billed cuckoo habitat consists of low to mid-level riparian forests dominated by
cottonwoods and willows. Suitable habitat is approximately 100 to 198 acres and wider than
200 meters;marginal habitat is approximately 20 to 100 acres and 100 to 200 meters wide;and
unsuitable habitat is smaller than approximately 37 acres and less than 100 meters wide (Wiles
& Kalasz, 2017). Twenty sightings of the yellow-billed cuckoo have been confirmed in
Washington between the 1950s and 2017; none of these sightings were of breeding birds.
Sixteen of these 20 confirmed sightings were east of the Cascades; and the sighted birds were
likely vagrants or migrants (Wiles&Kalasz,2017). The subject property is partially developed
and vegetated but is not within a riparian area and is surrounded by residential housing and
development, with no documented occurrences of yellow-billed cuckoo in the vicinity. The
most recent sighting was recorded approximately 31 miles to the southeast in the vicinity of
Sultan in 1979 (eBird, n.d). As the adjacent forested areas are typically smaller than the
required habitat blocks and are comprised predominantly of red alder and evergreen trees,no
suitable potential habitat is present on or near the site, and yellow-billed cuckoo is not likely
present on or within 300 feet of the site.
The Northwestern pond turtle is a medium-size aquatic turtle. In Washington, they are only
known to inhabit ponds and lakes,but also rely on adjacent upland habitats with extensive sun
exposure such as prairies in the Puget Sound,oak-pine savanna,open forested in the Columbia
Gorge, and pasture in order to lay eggs, disperse to new waters, overwinter, and aestivate.
Northwestern pond turtles are omnivorous,relying on insects, aquatic vertebrates, and plants
as food sources. Historical declines in their numbers may be attributed to hunting or collection
as food, alteration or loss of habitat, and introduced predators including bullfrogs and
largemouth bass. A small wetland with ponding exists approximately 75 feet offsite to the
2419.0002-Lindsay Annexation 17 Soundview Consultants LLC
Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
west;however,the conditions surrounding the ponded area are degraded by mowed lawns and
field. As such, Northwestern pond turtle is likely not present on or within 300 feet of the
subject property.
Bull trout have the most specific habitat requirements of salmonids. They require cold water
temperatures, clean stream substrates for spawning and rearing, complex habitats including
streams with riffles and deep pools,undercut banks and large logs,and they also rely on river,
lake, and ocean habitats that connect to headwater streams for annual spawning and feeding
migrations (Shellberg,2002). In Washington,bull trout are typically found in major tributaries
from the Cascades that flow into the Puget Sound as well as major tributaries for the Olympic
Mountains that flow into the Hood Canal, Straight of Juan de Fuca, and the Pacific Ocean
(USFWS, 2015). WDFW and NWIFC-SWIFD indicate the presumed presence of bull
trout/Dolly Varden and WDFW PHS indicates the occurrence and migration of bull trout
within Stream Z onsite and adjacent to the subject property to the west. However,the portion
of the Stream Z onsite is indicated as a Type Ns stream with likely downstream fish barriers,
therefore bull trout are not likely present on or within 300 feet of the subject property.
B. Ponds and their submerged aquatic beds that provide fish or wildlife habitat;
No ponds have been identified on or within 300 feet of the subject property.
C. Segments of natural waters and periodically inundated areas of their associated wetlands that are used by
salmonids for off-channel habitat;
Wetlands and streams are discussed in Section 5.2 and 5.3. Regulatory considerations are
discussed in Chapter 6.
D. Lakes,ponds, and streams planted with game fish (defined at RCWI 77.09.020), including those planted
under the auspices of a federal, state, local, or tribal programs, or which supportpriority fish species as identified
by the department offish and wildlife;
No lakes, ponds, or streams planted with game fish are present on or within 300 feet of the
subject property.
E. State natural area preserves and natural resource conservation areas;
No state natural area preserves of natural resource conservation areas are identified on or
within 300 feet of the subject property.
E Habitats or species of local importance;
No habitats or species of local importance were identified on or within 300 feet of the
subject property.

Chapter 6. Regulatory Considerations
The site investigations in the spring of 2024 identified four potentially-regulated wetlands (Wetlands
A - D) and one stream (Stream Z) on the subject property. The investigation also identified one
potentially regulated offsite wetland (Wetland 1). No other potentially-regulated wetlands,
waterbodies, fish and wildlife habitat, or priority species were identified on or within 300 feet of the
subject property.
6.1 Local Critical Areas Requirements
6.1.1 Wetland Buffers
AMC 20.93.8O0(a) has adopted the current wetland rating system for western Washington (Hruby,
2014). Category IV wetlands have the lowest levels of functions (scoring fewer than 16 points) and
are often heavily disturbed. These are wetlands that functions may be replaced, or in some cases
improved. Category III wetlands include wetlands with moderate level of functions (scoring between
16 and 19 points) that have generally been disturbed in some ways and are often less diverse or more
isolated in the landscape than Category 11 wetlands.
Per AMC 20.93.830,wetland buffers are based on wetland category and the level of habitat functions.
Wetlands A and D are classified as Category IV wetlands per Arlington Municipal Code (AMC)
20.93.800 and are subject to a standard 40-foot buffer regardless of habitat score per AMC 20.93.830
Table 20.93-4 with the required use of minimization measures outlined in AMC Table 20.93-5.
Wetlands B,C,and 1 are classified as Category III wetlands per AMC 20.93.800 with moderate habitat
scores of(6 or 7) and are subject to a standard 110-foot buffer per AMC 20.93.830 Table 20.93-4 with
the required use of minimization measures outlined in AMC Table 20.93-5. Table 8 presents the
standard wetland buffer widths for the identified wetlands.

6.1.2 Stream Buffers
Stream Z is considered to be a Type N (non-fish bearing) water according to DNR Stream Typing
with a likely downstream fish barrier on parcel 31052600100800. Due to the shallow flows observed
within Stream Z during the spring 2024 site investigations, and as the stream channel onsite and
adjacent to the site is heavily altered and has extensive vegetation growing within the channel, Stream
Z is considered to be a Type Ns (non-fish bearing seasonal) water per AMC 20.93.700 and is subject
to a standard 50-foot buffer per AMC 20.93.730 Table 20.93-3.
6.2 State and Federal Considerations
On January 18,2023,USACE and EPA published a revised definition of"Waters of the United States"
(USACE and EPA,2023a). The revised rule became effective on March 20, 2023. On May 25, 2023,
the U.S. Supreme Court issued a decision affecting the definition of Waters of the United States, or
"WOTUS", in Sackett Et Ux. V Environmental Protection Agency Et Al. On August 29, 2023, the US
EPA and USACE issued a final rule to amend the final"Revised Definition of`Waters of the United
States"' rule. The amendment conforms the definition of"Waters of the United States" to the U.S.
Supreme Court's decision in the Sackett Et Ux.V Environmental Protection Agency Et Al case. The
revised and amended definition of"Waters of the United States"is as follows:
(a) Waters of the United States means:
(1) iVaters which are: (i) Currently used, or mere used in the past, or may be susceptible to use in interstate or
foreign commerce, including all waters which are subject to the ebb and flow of the tide; (ii) The territorial seas;or
(iii)Interstate waters;
(2) Impoundments of waters otherwise defined as waters of the United States under this definition, other than
impoundments of waters identified underparagraph (a)(5) of this section;
(3)Tributaries of waters identified in paragraph (a)(1)or(2)of this section:that are relatively permanent, standing
or continuously flowing bodies of water;
(4) Wletlands adjacent to the following waters: (i) Waters identified in paragraph (a)(9) of this section; or (ii)
Relatively permanent, standing or continuously flowing bodies of water identified in paragraph (a)(2) or (a)(3) of
this section and with a continuous surface connection to those waters;
(5) Intrastate lakes and ponds not identified in paragraphs (a)(1) through (4) of this section that are relatively
permanent, standing or continuously flowing bodies of water with a continuous surface connection to the waters
identified in paragraph (a)(1) or(a)(3) of this section;
(b) The following are not "waters of the United States"even where they otherwise meet the terms of paragraphs (a)(2)
through (5) of this section:
(9) Wlaste treatment ystems, including treatment ponds or lagoons, designed to meet the requirements of the Clean
WlaterAct;
(2)Prior converted cropland designated by the Secretary of Agriculture. The exclusion would cease upon a change
of use, which means that the area is no longer available for the production of agricultural commodities.
Notwithstanding the determination of an area's status as prior converted cropland by any other Federal agency,for
2419.0002-Lindsay Annexation 21 Soundview Consultants LLC
Wetland&Fish&Wildlife Habitat Assessment Report June 20,2025
the purposes of the Clean Water Act, the final authority regarding Clean Water Act jurisdiction remains with
EPA;
(3) Ditches (including roadside ditches) excavated wholly in and draining only dry land and that do not carry a
relatively permanent flow of water;
(4)Artificially irrigated areas that would revert to dry land if the irrigation ceased;
(S)Artificial lakes or ponds created by excavating or diking dry land to collect and retain water and which are
used exclusively for such purposes as stock Wate in irrigation, settling basins, or rice growing
(6) Artificial reflecting or swimming pools or other small ornamental bodies of water created by excavating or
diking dry land to retain water for primarily aesthetic reasons;
(7) Vate f lled depressions created in dry land incidental to construction activity and pits excavated in dry land for
the purpose of obtaining fill, sand, orgravel unless and until the construction or excavation operation is abandoned
and the resulting body of water meets the definition of waters of the United States;and
(8) Swales and erosional features (e.g.,gullies, small washes) characterised by low volume, infrequent, or short
duration flow.
The 2023 revised and amended definition of Waters of the United States defines"adjacent"as"having
a continuous surface connection."
Stream Z connects into Edgecomb Creek and then Middle Fork Quilceda Creek which connects into
the main stem of Quilceda Creek which outlets directly to Puget Sound a WOTUS. As such, Stream
Z is regulated as a WOTUS under Category (a)(3) above. Wetlands A - D and offsite Wetland 1 all
share hydrological connections to the onsite ditches that outlet into Edgecomb Creek offsite to the
west; thus Wetlands A- D and Wetland 1 are likely federally regulated wetlands under the CWA, and
as such are likely regulated as WOTUS under category (a)(4).
All identified wetlands (Wetlands A— D and 1), and Stream Z are regulated as surface waters of the
state by the WSDOE under the Revised Code of Washington (RCW) 90.48. If a future project
required direct wetland impacts,authorization from USACE would be required,and coordination with
WSDOE would also be necessary.

to the Lindsay Annexation 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. Because of such changes,our observations and conclusions applicable to this project may need
to be revised wholly or in part.
The critical area determinations by Soundview Consultants LLC are based on conditions present at
the time of the site inspection and considered preliminary until the presence or absence and location
of critical areas are validated by the jurisdictional agencies. Validation of the critical area
determinations by the regulating agencies provides a certification,usually written, that the critical area
boundaries or lack thereof 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.
Since critical areas are dynamic communities affected by both natural and human activities, changes
in critical area determinations and/or boundaries may be expected; therefore, critical area
determinations cannot remain valid for an indefinite period of time. Local agencies typically recognize
the validity of critical area determinations for a period of 5 years after completion of a wetland
delineation and fish and wildlife habitat assessment report. Development activities on a site 5 years
after the completion of this report may require revision of the critical area determinations and/or
delineations. In addition, changes in government codes, regulations, or laws may occur. Because of
such changes, our observations and conclusions applicable to this site may need to be revised wholly
or in part.

HGM Classification of Wetlands in Western Washington
For questions 1-7,the criteria described must apply to the entire unit being rated.
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?
❑X NO - go to 2 ❑ YES -the wetland class is Tidal Fringe - 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 - Saltwater Tidal Fringe (Estuarine) DYES - Freshwater Tidal Fringe
Ifyour 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.
❑X NO - go to 3 ❑YES - The wetland class is Flats
Ifyour 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 anytime 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).
❑X NO - go to 4 DYES -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.
❑X NO - go to 5 ❑YES- 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-Version 2,July 2023
Wetland name or number 1
❑X NO - go to 6 ❑YES- 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 sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
❑NO - go to 7 ❑X YES - 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 - go to 8 ❑YES -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
Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

WDFW Priority Habitats
See complete descriptions of Priority Habitats listed by WDFW,and the counties in which they can be found,in:
Washington Department of Fish and Wildlife.2008(current year,as revised).Priority Habitat and Species List.133 This list
was updated for consistency with guidance from WDFW.
This question is independent of the land use between the wetland unit and the Priority Habitat.All vegetated wetlands are
by definition a Priority Habitat but are not included in this list because they are addressed by this rating system.
Count how many of the following Priority Habitats are within 330 ft(100 m) of the wetland unit:
— Aspen Stands: Pure or mixed stands of aspen greater than 1 ac(0.4 ha).
— Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and
wildlife.This habitat automatically counts if mapped on the online map within 100m of the wetland.IIf not mapped,a
determination can be made in the field.
— Caves: A naturally occurring cavity,recess,void,or system of interconnected passages under the earth in soils,rock,ice,
or other geological formations and is large enough to contain a human.
— Cliffs: Greater than 25 ft(7.6 m)high and occurring below 5000 ft elevation.
— Fresh Deepwater:Lands permanently flooded with freshwater,including environments where surface water is
permanent and often deep,so that water,rather than air,is the principal medium within which the dominant organisms
live.Substrate does not support emergent vegetation. Do not select if Instream habitat is also present,or if the entire
deepwater feature is included in the wetland unit being rated(such as a pond with a vegetated fringe).
— Herbaceous Balds:Variable size patches of grass and forbs on shallow soils over bedrock.
X Instream:The combination of physical,biological,and chemical processes and conditions that interact to provide
functional life history requirements for instream fish and wildlife resources.Do not select if Fresh Deepwater habitat is
also present.
— Nearshore:Relatively undisturbed nearshore habitats.These include Coastal Nearshore,Open Coast Nearshore,and
Puget Sound Nearshore.
— Old-growth/Mature forests: Old-growth west of Cascade crest-Stands of at least 2 tree species,forming a multi-
layered canopy with occasional small openings;with at least 8 trees/ac(20 trees/ha)>32 in.(81 cm)diameter at breast
height(dbh)or>200 years of age.Mature forests-Stands with average diameters exceeding 21 in.(53 cm)dbh;crown
cover may be less than 100%;decay,decadence,numbers of snags,and quantity of large downed material is generally
less than that found in old-growth;80-200 years old west of the Cascade crest.

HGM Classification of Wetlands in Western Washington
For questions 1-7,the criteria described must apply to the entire unit being rated.
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?
ONO - go to 2 ❑ YES -the wetland class is Tidal Fringe - 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 - Saltwater Tidal Fringe (Estuarine) DYES - Freshwater Tidal Fringe
Ifyour 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.
ONO - go to 3 ❑YES - The wetland class is Flats
Ifyour 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 anytime 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).
❑X NO - go to 4 DYES -The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
❑X The wetland is on a slope (slope can be very gradual),
❑X 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,
❑X The water leaves the wetland without being impounded.
❑NO - go to 5 ❑X YES- 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-Effective January 1,2015
Wetland name or number A
❑NO - go to 6 ❑YES- 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 sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
❑NO - go to 7 ❑YES - 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 - go to 8 ❑YES -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
Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

HGM Classification of Wetlands in Western Washington
For questions 1-7,the criteria described must apply to the entire unit being rated.
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?
ONO - go to 2 ❑ YES -the wetland class is Tidal Fringe - 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 - Saltwater Tidal Fringe (Estuarine) DYES - Freshwater Tidal Fringe
Ifyour 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.
ONO - go to 3 ❑YES - The wetland class is Flats
Ifyour 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 anytime 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).
❑X NO - go to 4 DYES -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.
❑X NO - go to 5 ❑YES- 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-Version 2,July 2023
Wetland name or number B
❑X NO - go to 6 ❑YES- 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 sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
❑NO - go to 7 ❑X YES - 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 - go to 8 ❑YES -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
Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

WDFW Priority Habitats
See complete descriptions of Priority Habitats listed by WDFW,and the counties in which they can be found,in:
Washington Department of Fish and Wildlife.2008(current year,as revised).Priority Habitat and Species List.133 This list
was updated for consistency with guidance from WDFW.
This question is independent of the land use between the wetland unit and the Priority Habitat.All vegetated wetlands are
by definition a Priority Habitat but are not included in this list because they are addressed by this rating system.
Count how many of the following Priority Habitats are within 330 ft(100 m) of the wetland unit:
— Aspen Stands: Pure or mixed stands of aspen greater than 1 ac(0.4 ha).
— Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and
wildlife.This habitat automatically counts if mapped on the online map within 100m of the wetland.IIf not mapped,a
determination can be made in the field.
— Caves: A naturally occurring cavity,recess,void,or system of interconnected passages under the earth in soils,rock,ice,
or other geological formations and is large enough to contain a human.
— Cliffs: Greater than 25 ft(7.6 m)high and occurring below 5000 ft elevation.
— Fresh Deepwater:Lands permanently flooded with freshwater,including environments where surface water is
permanent and often deep,so that water,rather than air,is the principal medium within which the dominant organisms
live.Substrate does not support emergent vegetation. Do not select if Instream habitat is also present,or if the entire
deepwater feature is included in the wetland unit being rated(such as a pond with a vegetated fringe).
— Herbaceous Balds:Variable size patches of grass and forbs on shallow soils over bedrock.
— Instream:The combination of physical,biological,and chemical processes and conditions that interact to provide
functional life history requirements for instream fish and wildlife resources.Do not select if Fresh Deepwater habitat is
also present.
— Nearshore:Relatively undisturbed nearshore habitats.These include Coastal Nearshore,Open Coast Nearshore,and
Puget Sound Nearshore.
— Old-growth/Mature forests: Old-growth west of Cascade crest-Stands of at least 2 tree species,forming a multi-
layered canopy with occasional small openings;with at least 8 trees/ac(20 trees/ha)>32 in.(81 cm)diameter at breast
height(dbh)or>200 years of age.Mature forests-Stands with average diameters exceeding 21 in.(53 cm)dbh;crown
cover may be less than 100%;decay,decadence,numbers of snags,and quantity of large downed material is generally
less than that found in old-growth;80-200 years old west of the Cascade crest.

HGM Classification of Wetlands in Western Washington
For questions 1-7,the criteria described must apply to the entire unit being rated.
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?
ONO - go to 2 ❑ YES -the wetland class is Tidal Fringe - 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 - Saltwater Tidal Fringe (Estuarine) DYES - Freshwater Tidal Fringe
Ifyour 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.
ONO - go to 3 ❑YES - The wetland class is Flats
Ifyour 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 anytime 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).
❑X NO - go to 4 DYES -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.
❑X NO - go to 5 ❑YES- 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

Wetland name or number C
❑X NO - go to 6 ❑YES- 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 sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
❑NO - go to 7 ❑X YES - 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

outlet.
❑NO - go to 8 ❑YES -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
Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

WDFW Priority Habitats
See complete descriptions of Priority Habitats listed by WDFW,and the counties in which they can be found,in:
Washington Department of Fish and Wildlife.2008(current year,as revised).Priority Habitat and Species List.133 This list
was updated for consistency with guidance from WDFW.
This question is independent of the land use between the wetland unit and the Priority Habitat.All vegetated wetlands are
by definition a Priority Habitat but are not included in this list because they are addressed by this rating system.
Count how many of the following Priority Habitats are within 330 ft(100 m) of the wetland unit:
— Aspen Stands: Pure or mixed stands of aspen greater than 1 ac(0.4 ha).
— Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and
wildlife.This habitat automatically counts if mapped on the online map within 100m of the wetland.IIf not mapped,a
determination can be made in the field.
— Caves: A naturally occurring cavity,recess,void,or system of interconnected passages under the earth in soils,rock,ice,
or other geological formations and is large enough to contain a human.
— Cliffs: Greater than 25 ft(7.6 m)high and occurring below 5000 ft elevation.
— Fresh Deepwater:Lands permanently flooded with freshwater,including environments where surface water is
permanent and often deep,so that water,rather than air,is the principal medium within which the dominant organisms
live.Substrate does not support emergent vegetation. Do not select if Instream habitat is also present,or if the entire
deepwater feature is included in the wetland unit being rated(such as a pond with a vegetated fringe).
— Herbaceous Balds:Variable size patches of grass and forbs on shallow soils over bedrock.
X Instream:The combination of physical,biological,and chemical processes and conditions that interact to provide
functional life history requirements for instream fish and wildlife resources.Do not select if Fresh Deepwater habitat is
also present.
— Nearshore:Relatively undisturbed nearshore habitats.These include Coastal Nearshore,Open Coast Nearshore,and
Puget Sound Nearshore.
— Old-growth/Mature forests: Old-growth west of Cascade crest-Stands of at least 2 tree species,forming a multi-
layered canopy with occasional small openings;with at least 8 trees/ac(20 trees/ha)>32 in.(81 cm)diameter at breast
height(dbh)or>200 years of age.Mature forests-Stands with average diameters exceeding 21 in.(53 cm)dbh;crown
cover may be less than 100%;decay,decadence,numbers of snags,and quantity of large downed material is generally
less than that found in old-growth;80-200 years old west of the Cascade crest.

HGM Classification of Wetlands in Western Washington
For questions 1-7,the criteria described must apply to the entire unit being rated.
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?
ONO - go to 2 ❑ YES -the wetland class is Tidal Fringe - 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 - Saltwater Tidal Fringe (Estuarine) DYES - Freshwater Tidal Fringe
Ifyour 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.
ONO - go to 3 ❑YES - The wetland class is Flats
Ifyour 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 anytime 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).
❑X NO - go to 4 DYES -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.
❑X NO - go to 5 ❑YES- 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-Version 2,July 2023
Wetland name or number D
❑X NO - go to 6 ❑YES- 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 sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
❑NO - go to 7 ❑X YES - 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 - go to 8 ❑YES -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
Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

Washington Department of Fish and Wildlife.2008(current year,as revised).Priority Habitat and Species List.133 This list
was updated for consistency with guidance from WDFW.
This question is independent of the land use between the wetland unit and the Priority Habitat.All vegetated wetlands are
by definition a Priority Habitat but are not included in this list because they are addressed by this rating system.
Count how many of the following Priority Habitats are within 330 ft(100 m) of the wetland unit:
— Aspen Stands: Pure or mixed stands of aspen greater than 1 ac(0.4 ha).
— Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and
wildlife.This habitat automatically counts if mapped on the online map within 100m of the wetland.IIf not mapped,a
determination can be made in the field.
— Caves: A naturally occurring cavity,recess,void,or system of interconnected passages under the earth in soils,rock,ice,
or other geological formations and is large enough to contain a human.
— Cliffs: Greater than 25 ft(7.6 m)high and occurring below 5000 ft elevation.
— Fresh Deepwater:Lands permanently flooded with freshwater,including environments where surface water is
permanent and often deep,so that water,rather than air,is the principal medium within which the dominant organisms
live.Substrate does not support emergent vegetation. Do not select if Instream habitat is also present,or if the entire
deepwater feature is included in the wetland unit being rated(such as a pond with a vegetated fringe).
— Herbaceous Balds:Variable size patches of grass and forbs on shallow soils over bedrock.
— Instream:The combination of physical,biological,and chemical processes and conditions that interact to provide
functional life history requirements for instream fish and wildlife resources.Do not select if Fresh Deepwater habitat is
also present.
— Nearshore:Relatively undisturbed nearshore habitats.These include Coastal Nearshore,Open Coast Nearshore,and
Puget Sound Nearshore.
— Old-growth/Mature forests: Old-growth west of Cascade crest-Stands of at least 2 tree species,forming a multi-
layered canopy with occasional small openings;with at least 8 trees/ac(20 trees/ha)>32 in.(81 cm)diameter at breast
height(dbh)or>200 years of age.Mature forests-Stands with average diameters exceeding 21 in.(53 cm)dbh;crown

Does the wetland have at least 1 contiguous acre of forest that meets one of these criteria for the WA
Department of Fish and Wildlife's forests as priority habitats?If you answer YES you will still need to rate
the wetland based on its functions.
—Old-growth forests(west of Cascade crest):Stands of at least two tree species,forming a multi-layered
canopy with occasional small openings;with at least 8 trees/ac(20 trees/ha)that are at least 200 years of
age OR have a diameter at breast height(dbh)of 32 in (81 cm)or more.
—Mature forests(west of the Cascade Crest):Stands where the largest trees are 80-200 years old OR the
species that make up the canopy have an average diameter(dbh)exceeding 21 in (53 cm).
El Yes= Category I ❑x No=Not a forested wetland for this section
SC 5.0. Wetlands in Coastal Lagoons
Does the wetland meet all of the following criteria of a wetland in a coastal lagoon?
—The wetland lies in a depression adjacent to marine waters that is wholly or partially separated from
marine waters by sandbanks,gravel banks,shingle,or, less frequently, rocks
—The lagoon in which the wetland is located contains ponded water that is saline or brackish (>0.5 ppt)
during most of the year in at least a portion of the lagoon (needs to be measured near the bottom)
—The lagoon retains some of its surface water at low tide during spring tides
❑Yes-Go to SC 5.1 ❑x No=Not a wetland in a coastal lagoon
SC 5.1. Does the wetland meet all of the following three conditions?
—The wetland is relatively undisturbed (has no diking, ditching,filling,cultivation,grazing),and has less
than 20%cover of aggressive,opportunistic plant species(see list of species in H 1.5 in the manual).
—At least 3%of the landward edge of the wetland has a 100 ft buffer of shrub,forest,or un-grazed or un-
mowed grassland.
—The wetland is larger than 1/10 ac(4350 ftz) ❑Yes=Category I ❑No=Category II
SC 6.0. Interdunal Wetlands
Is the wetland west of the 1889 line(also called the Western Boundary of Upland Ownership or WBUO)? If
you answer yes you will still need to rate the wetland based on its habitat functions.
In practical terms that means the following geographic areas:
— Long Beach Peninsula: Lands west of SR 103
— Grayland-Westport: Lands west of SR 105
— Ocean Shores-Copalis: Lands west of SR 115 and SR 109 and Ocean Shores Blvd SW, including lands west
of E.Oceans Shores Blvd SW. ❑Yes-Go to SC 6.1 x❑No=Not an interdunal wetland for rating
SC 6.1. Is the wetland 1 ac or larger and scores an 8 or 9 for the habitat functions on the form (rates H,H,H or H,H,M
for the three aspects of function)? ❑Yes=Category I ❑No-Go to SC 6.2
SC 6.2. Is the wetland 1 ac or larger,or is it in a mosaic of wetlands that is 1 ac or larger?
❑Yes=Category II ❑No-Go to SC 6.3
SC 6.3. Is the unit between 0.1 and 1 ac,or is it in a mosaic of wetlands that is between 0.1 and 1 ac?
