Wetland and Stream Delineation Report Otak
Executive Summary
Jefferson County Public Works is planning to construct a segment of the Olympic Discovery Trail Project
approximately three miles in length from the south end of the Larry Scott Trail at Milo Curry Road running east
and south to Anderson Lake State Park in Jefferson County. The trail will include clearing, grading, and fill during
construction. The project aims to accommodate pedestrians, runners, bicyclists, equestrians, and other non-
motorized/recreational trail users. Otak, Inc. (Otak) was hired by Jefferson County to complete a wetland and
stream delineation report to document baseline conditions and support project design and environmental permit
applications.
This report was completed by reviewing background information, delineating wetland and stream boundaries in
the field, classifying wetlands and stream habitats, and determining buffer widths per Jefferson County Code
(JCC) Chapter 18.22 (Critical Areas). Critical areas reviewed for this report include wetlands and fish and wildlife
habitat conservation areas (FWHCAs). Biologists from Otak conducted the field investigation on March 2 through
March 4, 2022. The study area for this report includes the right of way and easement boundary along South
Discovery Road and 4 Corners Road, the entire width of the utility easement trail section south of 4 Corners
Road, and the trail easement corridor from the utility easement to Anderson Lake State Park. Areas outside of the
right of way and easements were visually assessed to identify wetlands or streams with buffers that could extend
back into the study area. Wetland and stream boundaries were delineated in the field with pink and orange
flagging for wetlands and streams, respectively.
Habitat assessments for sensitive fish, wildlife, and plant species were completed in the field. Suitable habitat for
sensitive fish, wildlife, and plant species was not observed during the field investigation due to previous site
disturbances from development, logging, forest management, and maintenance of the utility corridor.
Twenty wetlands and three watercourses were identified in the study area. Wetland habitats consist of palustrine
forested, scrub-shrub, and emergent Cowardin classes. Wetlands have riverine, depressional, and slope
hydrogeomorphic classes. Wetland buffer widths range from 40 to 225 feet per JCC 18.22.730 (Standard Wetland
Buffer Widths). Wetlands were rated using the Washington State Wetland Rating System for Western Washington
– 2014 Update (Hruby 2014) per JCC 18.22.710 (Classification/designation). Watercourses within the study area
include three non-fish, seasonal streams with 50-foot buffer widths.

Wetland and Stream Delineation Report Otak
Chapter 1. Introduction
Otak, Inc. (Otak) was hired by Jefferson County Public Works (County) to complete a Wetland and Stream
Delineation Report to document baseline environmental conditions within the study area for the proposed Olympic
Discovery Trail extension project. Information this report will be used to support permitting with local, state, and
federal resource agencies. Critical areas and habitats covered in this report include wetlands and fish and wildlife
habitat conservation areas (FWHCAs). The project is an approximately three mile long pedestrian trail from the
south end of the Larry Scott Trail at Milo Curry Road running east and south to Anderson Lake State Park in
Jefferson County
This report was completed by reviewing background information and completing field work in March 2022 to
delineate wetlands and streams within the acquired easements and existing right of way (ROW) for the project.
The potential presence of suitable habitat for sensitive wildlife species and species of local importance was also
assessed. This report documents wetland and stream boundaries and classifications, associated buffer widths,
and existing wildlife habitat in the study area.
1.1 Project Location and Landscape Setting
The project is generally located within an approximately three mile long existing road and utility corridor and
previously logged forest lands. Adjacent land use along South Discovery Road at the north end of the project
includes a United Postal Service Pickup facility, an auto wrecking yard, a storage facility, a gas station, and the
Jefferson Transit Park and Ride. Land use outside of the utility corridor is mixed rural residential and logging, in
unincorporated Jefferson County, Washington (Appendix B: Figure 1–Vicinity Map). The project corridor is located
within easements along South Discovery Road and Four Corners Road. Anderson Lake State Park abuts the
southeast terminus of the study area where the trail is expected to continue on to State Park property in the
future.
The project is located in Sections 4 and 9, of Township 29 North, Range 01 West, and Sections 32, and 33 of
Township 30 North, Range 01 West, located entirely in Water Resource Inventory Areas (WRIA) 17 – Quilcene –
Snow watershed.
1.2 Project Description
This project aims to construct a segment of the Olympic Discovery Trail Project approximately three miles in
length located from the south end of the Larry Scott Trail at Milo Curry Road running east and south to Anderson
Lake State Park in Jefferson County. The trail will be part of a coordinated regional system that will eventually
connect the Larry Scott Trail to Discovery Bay as part of the Eaglemount segment of the Olympic Discovery Trail.
By constructing the trail segment, pedestrians, runners, bicyclists, equestrians, and other trail users with non-
motorized equipment will have an alternative to Highway 20 for travel between the existing trail segments. This
project will subsequently increase community use of the existing trail systems by increasing the accessibility of
the north and south trails and lowering the overall risk to non-motorized traffic along Highway 20.
1.3 Study Area
The study area for this report included areas of potential ground disturbance plus 300 feet in accordance with
JCC 18.22.960(3) (Wetland reports) (Appendix B: Figure 2–Study Area Map). The study area includes the right of
way and easement boundary along South Discovery Road and 4 Corners Road, the entire width of the utility
easement trail section south of 4 Corners Road, and the trail easement corridor from the utility easement to
Anderson Lake State Park. Areas outside of the right of way and easements were visually assessed to identify
wetlands or streams with buffers that could extend back into the study area. Wetland and stream boundaries
were delineated in the field with pink and orange flagging for wetlands and streams, respectively.

Chapter 2. Methods
This chapter summarizes the methods used in accordance with local, state, and federal guidance in delineating
wetland and stream boundaries in Washington State. See Table A-1 in Appendix A for further details regarding
the methods used to produce this report.
2.1 Review of Available Published Information
Available published information was reviewed prior to the field investigation to identify any previously documented
wetlands, streams, habitat areas, or other pertinent site characteristics (e.g., vegetation community patterns,
topography, soils, or water courses) that would indicate the presence of wetlands and streams within the project
site. These maps are typically used as guidance, and do not supersede conditions in the field. As part of this effort
Otak biologists reviewed the following sources:
▪ Soil survey from the United States Natural Resources Conservation Service (NRCS) (NRCS 2022);
▪ National Wetlands Inventory (NWI) map (USFWS 2022);
▪ Washington Department of Natural Resources (WDNR) Forest Practices Application Mapping Tool
(WDNR 2022);
▪ Washington State Department of Fish and Wildlife (WDFW) Priority Habitat and Species (PHS) maps (WDFW
2022) and Statewide Washington Integrated Fish Distribution (SWIFD) (WDFW 2022a); and
▪ Jefferson County Public Lands Records (Jefferson County 2022).
Appendix B contains figures associated with the background review, including: an aerial photograph of the study
area (Figure 2), NWI map (Figure 3), NRCS Soils Map (Figure 4), WDNR Stream Typing Map (Figure 5), and
Jefferson County Public Land Records Map depicting wetlands, streams, and fish passage barriers (Figure 6).
Soil units mapped within the study area are listed in Table 2-1. Agnew silt loam, Alderwood gravelly sandy loam,
Cassolary sandy loam, Dick loamy sand, Hoypus gravelly sandy loam, Swantown gravelly sandy loam, Tukey
gravelly loam. No soils within the study area are classified as hydric soils.

Wetland and Stream Delineation Report Otak
The NWI mapper identifies four riverine wetland habitats within the study area. All four NWI-mapped wetlands are
identified as classification code R4SBC [Riverine (R), Intermittent (4), Streambed (SB), and the water regime as
Seasonally Flooded (C)].
Jefferson County Public Lands records shows the NWI-mapped wetlands within the study area as Washington
Department of Natural Resources (DNR) streams, and type the streams using the former DNR water typing
system. Three of the mapped streams are Type 5 (Non-Fish Seasonal) and one is Type 9 (unknown/untyped
mapped stream). No additional fish and wildlife habitat areas or wetlands are mapped within the study area. The
WDNR Forest Practices Application Mapping Tool maps three streams within the study area. All streams are
Type N (nonfish habitat), formerly Type 5 streams, without an associated description of seasonal or intermittent
flow. Type 9 streams are classified as unknown/untyped.
WDFW’s PHS on the Web does not identify any priority habitats and species in the project vicinity.
The SWIFD mapper identifies four National Hydrology Dataset (NHD) flowlines in the study area. No fish species
or habitat have been documented in the streams within the study area.
The U.S. Fish & Wildlife Service (USFWS) Information for Planning and Consultation (IPaC) tool lists the potential
presence of species listed as Threatened (T), Endangered (E), Candidate (C), and Proposed Similarity of
Appearance to a Threatened Taxon (PSAT) under the Endangered Species Act (ESA) in the study area. Three
bird species are listed within the study area, including Marbled Murrelet (Brachyramphus marmoratus) (T),
Streaked Horned Lark (Eremophila alpestris strigata) (T), and Yellow-Billed Cuckoo (Coccyzus americanus) (T).
ESA-listed fish species potentially present include Bull Trout (Salvelinus confluentus) (T) and Dolly Varden
(Salvelinus malma) (PSAT). ESA-listed insects potentially present within the study area include Monarch Butterfly
(Danaus plexippus) (C) and Talor’s Checkersport (Euphydryas Editha taylor) (E). Golden Paintbrush (Castilleja
levisecta) (T), a flowering plant, is also listed. The IPaC tool does not map any critical habitats within the study
area. Suitable habitat for these species was not observed during the field investigation as discussed in Section 3
of this report.
2.2 Precipitation Data and Analysis
2.2.1 Evaluation of the Growing Season
Wetland hydrologic conditions are considered present if soils are inundated or saturated to the surface
continuously for at least 5 percent of the growing season in most years (50 percent probability of recurrence)
(USACE 1987). The technical standard for disturbed or problematic sites requires 14 or more consecutive days of
flooding or ponding, or a water table 12 inches or less below the soil surface, during the growing season, at a
minimum frequency of 5 years in 10 (USACE 2010).
The beginning and ending dates of the growing season can be defined based on two indicators of biological
activity that are readily observable in the field: (1) above ground growth and development of vascular plants, and
(2) soil temperature. However, due to seasonal fluctuations from year to year the growing season dates may also
be approximated by the number of frost-free days, defined as the time from the last date in spring when the
ambient air temperature drops to 28°F, to the first date in fall when it drops to 28°F, over a 30-year period
(USACE 2010).
As such, the beginning and ending dates for the growing season for the project site were estimated from long-
term weather records (1993-2022) as the median dates (50 percent probability) for the first and last 28°F days at
the Sequim 2 E Climate Station. Based on long-term weather records the average start and end dates for the
growing season for the area are April 2, and November 5, respectively, for a total growing season of 217 days
(NRCS 2022a). Continuing wetland hydrologic conditions must be present for at least 11 consecutive days during
the growing season for this site.

2.2.2 Precipitation Data during Field Investigation
The field survey for the project was conducted on March 2 - March 4, 2021. The area received 1.43 inches of
precipitation in the two-week period (February 15 – March 1) prior to the field survey as measured at the Sequim
2 E Climate Station (NRCS 2022a). Precipitation amounts for the three months preceding the field survey were
above normal in December 2021, below normal in January 2022, and normal in February 2022 (Table 3).

2.3 Field Investigation
Wetland and stream boundaries were delineated in the field by Otak biologists from March 2 to March 4, 2022.
Wetlands and streams were delineated within the easements and right of way where access was granted, and
areas outside of easements and right of way were visually assessed using field indicators such as changes in
vegetation communities.
2.3.1 Wetlands
In accordance with federal, state, and local guidance and regulations, Otak biologists delineated wetlands within
the study area using the three-parameter approach detailed in the Corps of Engineers Wetlands Delineation
Manual (USACE 1987), and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE 2010). Following routine methodology,
data on vegetation, soils, and hydrology were collected at paired (wetland/upland) data points for wetlands that
could be accessed within the easements associated with the project. The USACE wetland determination data
forms for the data points are provided in Appendix C.
Vegetation
Representative upland and wetland vegetation communities were documented at each data point during the field
survey. Typically, three vegetation strata are inventoried at each data point, including trees within a 30-foot
diameter plot, shrubs within a 15-foot diameter plot, and non-woody herbaceous plants (including forbs, grasses,
sedges, and rushes) within a 5-foot diameter plot. Plant species in each stratum were identified and absolute
percent cover was recorded. Each species was listed following the scientific nomenclature given in the United
States Department of Agriculture (USDA) PLANTS database (NRCS 2022b). The wetland indicator status for
each species was assigned using the 2020 National Wetland Plant List for the Western Mountains, Valleys &
Coast Region (USACE 2020).
The dominance test was the primary indicator used to determine the presence or absence of hydrophytic
vegetation. A data point is considered to have a hydrophytic vegetation community if more than 50 percent of the
dominant species have an indicator status of facultative (FAC), facultative-wetland (FACW), or obligate (OBL).
Dominant species are defined as those that individually or collectively account for more than 50 percent of the
total areal coverage of vegetation in the stratum, plus any other species that, by itself, accounts for at least 20
percent of the total areal coverage (USACE 2010). If more than 50 percent of the dominant plant species in a
Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 5
Wetland and Stream Delineation Report Otak
community have wetland indictor status of OBL, FACW, or FAC, then the plant community is considered
hydrophytic (wetland).
Soils
Per U.S. Army Corps of Engineers (USACE) protocol, soil samples were obtained at representative data points by
digging a pit to a depth of at least 18 inches if possible to determine the presence or absence of hydric soil
indicators using the Field Indicators of Hydric Soils in the United States, Version 8.2 (NRCS 2018). Soil colors
were evaluated against a Munsell® soil color chart (Gretag/Macbeth 2000) to distinguish hydric from non-hydric
soils.
Hydric soils are defined as soils that are saturated, flooded, or ponded long enough during the growing season to
develop anaerobic conditions in the upper part of the soil profile (USACE 2010). Hydric soils may exhibit certain
characteristics that can be observed in the field; such as: high organic content, accumulation of sulfidic material,
greenish or bluish-gray color (gley formation), depleted matrices, and development of redoximorphic features.
Hydrology
Wetland hydrologic conditions are considered present if, during the growing season, an area has 14 or more
consecutive days of flooding or ponding; or a water table 12 inches or less below the soil surface, during the
growing season at a minimum frequency of 5 years in 10 (USACE 1987 and 2010). The presence of primary and
secondary wetland hydrologic indicators was determined at each wetland data point.
Primary indicators of wetland hydrology may include, but are not limited to, surface water, soil saturation within 12
inches of the surface, shallow water table, and evidence of previous water inundation or saturation (e.g.,
watermarks, algal mats, sediment deposits). Secondary indicators may include wetland drainage patterns,
geomorphic position, stunted or stressed plants, and water-stained leaves. When at least one primary or two
secondary indicators were observed, wetland hydrology was determined to occur during the growing season long
enough to result in wetland hydrology conditions.
2.3.2 Ordinary High Water Mark
The ordinary high water mark (OHWM) along streams within the study area were determined in the field based on
the methodology outlined in USACE Regulatory Guidance Letter 05-05 (USACE 2005) and Determining the
Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Ecology 2016).
Identification of OHWM was based on the evaluation of stream physical characteristics, such as: presence of bed
and banks, a natural line impressed on the bank, change in sediment and vegetation characteristics, wracking,
erosion/scour, and silt deposits.
2.3.3 Fish and Wildlife Habitat Conservation Areas
Fish and Wildlife Habitat Conservation Areas (FWHCAs) include those areas that serve a critical role in sustaining
needed habitat and species for the functional integrity of the ecosystem. FWHCAs are identified as being of
critical importance to the maintenance of endangered, threatened, or sensitive species of fish, wildlife or plants, or
designated habitats and species of local importance per JCC 18.22.600-660 (Article VI. Fish and Wildlife Habitat
Conservation Areas), including rivers, streams, shellfish areas, kelp and eelgrass beds, forage fish spawning
areas, naturally occurring ponds less than 20 acres, aquatic resources planted wit game fish, natural preserves,
and state wildlife areas.
Habitats within the study area and the surrounding vicinities were assessed in the field by Otak biologists to
determine potential suitability for sensitive fish, wildlife and plant species. The USFWS IPaC mapping tool was
queried for the potential presence of federally-listed ESA species as provided in Section 2.1 of this report.
WDFW’s PHS on the Web does not identify any priority habitats or species with the project vicinity. Suitable
habitat for sensitive fish, wildlife, and plant species was not observed during the field investigation as discussed in
Section 3 of this report.

Wetland and Stream Delineation Report Otak
Rivers and streams are also designated as FWHCAs (JCC 18.22.610). Rivers and streams are assigned
prescriptive FWHCA Buffers per Table 18.22.630(1) (Stream Buffers). Four streams are mapped within the study
area by WDNR FPMAT, NHD, and Jefferson County Public Land Resources map applications (Section 2.1 f this
report). Results of the field delineation and habitat assessment are provided in Section 3.3 (Existing Conditions).
2.4 Wetland and Stream Classification and Ratings
Wetlands in the study area were classified according to Classification of Wetlands and Deepwater Habitats of
United States (Cowardin, et al. 1979), and the hydrogeomorphic (HGM) wetland classification system as adopted
by Hruby (2014). Wetland functions were rated using the Washington State Wetland Rating System for Western
Washington – 2014 Update (Hruby 2014) per JCC 18.22.710 (Classification/designation). Wetland standard buffer
widths were determined based on wetland category/characteristics, habitat score, and a moderate level of land
use intensity per JCC 18.22.730(6)(d)(i) (Protection Standards). Wetland buffer conditions were qualitatively
assessed based on vegetation cover, land use, and presence of invasive species. Wetlands and streams that
were identified outside of the easements were rated to determine if buffer widths could potentially extend into
project impact areas. Stream classification and buffer widths were determined according to JCC 18.22.630
(Protection Standards).
2.5 Mapping Methods
Wetlands and streams (OHWM) boundary flags were professionally surveyed after the field delineation was
completed. Any additional potential stream and wetland areas within 300 feet of study area was estimated using
aerial photography, lidar imagery, and observations made during the field investigation. Survey data was
transferred to Geographic Information Systems software, ArcGIS Pro version 2.8.7, to prepare exhibits for this
report (Appendix B: Figure Set 7).

Chapter 3. Existing Conditions
Otak biologists identified twenty wetlands and three watercourses in the study area as shown in Figure Set 7 in
Appendix B. Wetland classes, ratings, sizes, and buffer widths are summarized in Table 3-1, and stream
characteristics are summarized in Table 3-2. Species and wildlife habitat conservation areas are addressed in
Section 3.3. Wetland determination data forms are provided in Appendix C, and Washington State Department of
Ecology (Ecology) wetland rating forms are provided in Appendix D. Site photographs are provided in Appendix E.
3.1 Wetlands
Wetland 1. Wetland 1 is located northwest of Anderson Lake State Park and is partially within the trail easement.
The majority of Wetland 1 is located north of the trail easement. The area, including Wetland 1, was last logged in
2016. The wetland has a depressional HGM class with palustrine scrub-shrub (PSS) and forested (PFO)
Cowardin habitat classes. Dominant plant species within the wetland are salmonberry (Rubus spectabilis), red
alder (Alnus rubra), and common rush (Juncus effusus). The wetland is bordered by uplands with a similar plant
community with the addition of western swordfern (Polystichum munitum) and salal (Gaultheria shallon). The
wetland boundary was determined by the lack of hydric soil and wetland hydrology indicators in the uplands.
Photographs 1 and 2 in Appendix E show the typical habitat conditions within the wetland unit.
Wetland 2. Wetland 2 is located east of Wetland 1 and extends south into Anderson Lake State Park. The
wetland has a depressional HGM class with a PFO Cowardin class. The wetland is dominated by an overstory of
red alder, a scrub-shrub community of salmonberry, and an understory of slough sedge (Carex obnupta), lady
fern (Athyrium cyclosorum), and common rush. Uplands adjacent to the wetland unit include Douglas-fir
(Pseudotsuga menziesii), western redcedar (Thuja plicata), salmonberry, and western swordfern. Photographs 3
and 4 show habitat conditions within the wetland unit.
Wetland 3. Wetland 3 is a small (<0.01 acre) depressional wetland located approximately 15-feet north of
Wetland 2 and 15-feet south of Wetland 4. The Cowardin class present within the wetland unit is PSS, with
dominant vegetation including salmonberry and common rush. Ponded water was present within the unit. Woody
debris piles are present from previous logging in and near the wetland. Upland vegetation bordering the unit
includes salmonberry and western swordfern. Photographs 5 through 7 show the upland buffer conditions and
wetland habitat conditions for Wetland 3.
Wetland 4. Wetland 4 is located north and east of Wetland 3 and extends north and east outside of the trail
easement. The depressional wetland is dominated by palustrine emergent (PEM), PSS, and PFO Cowardin
habitat classes. An overstory of red alder occupies the tree stratum, areas of salmonberry dominate the scrub
stratum, and open areas of water parsley (Oenanthe sarmentosa) form the herb stratum. Flowing water is present
within the wetland unit running from west to east. The wetland extends east, outside of the study area and
appears to have a hydrologic surface connection with Anderson Lake based on lidar imagery. Photographs 8
through 11 show habitat conditions within Wetland 4, and upland conditions outside of the wetland within
Anderson Lake State Park.
Wetland 5. Wetland 5 is located outside of the trail easement and within the north-south aligned utility corridor
near the southern extent of the study area. The boundaries of Wetland 5 were estimated based on clear
topographic changes, hydrophytic vegetation, and surface ponding to determine the buffer area that extends into
the trail easement. The unit is in an isolated depression perched on a hillslope, bordered by the maintenance road
(moderate intensity land use) to the west and relatively undisturbed forest land (low intensity land use) to the east.
Wetland 5 is a depressional wetland with a PSS Cowardin habitat class with areas of seasonal ponding. The PSS
plant community is dominated by Douglas spirea (Spiraea douglasii). Photograph 14 shows typical vegetation and
standing water observed within Wetland 5.

3. Wetlands rated according to Hruby 2014 per JCC 18.22.710 (Classification/designation).
4. Wetland sizes are approximate for wetland extending past the easements based on delineated wetland edges, lidar imagery, NWI
mapping, and current aerial imagery.
5. Proposed land adjacent land use and are categorized and designated per JCC 18.22.730(6).
6. Wetland standard buffer width per JCC 18.22.730 is based on a combination of wetland category, habitat function score (from the wetland
rating form), and land use intensity.
Wetland 6. Wetland 6 is located north of Wetland 5 partially within the trail easement, and east of the utility
corridor maintenance road. The habitat class of the wetland unit is PSS, dominated by salmonberry and Pacific
willow (Salix lasiandra), and is classified as slope per the HNG classification system. Wetland 6 slopes east to
west and is bordered on the west side by the maintenance road embankment. Wetland hydrology is supported by
precipitation, shallow groundwater, and groundwater seeps. Upland vegetation consists of Douglas-fir,
salmonberry, and western swordfern. The WDNR Stream Typing map (Appendix B: Figure 5) identifies a Type N
waterbody where Wetland 6 is delineated. No evidence of a contemporary stream system (e.g., OHWM) is
present. Wetland 6 discharges water to the west through the culvert under the maintenance road, and presumably
to Discovery Bay during a portion of the year. Photographs 15 and 16 show typical habitat conditions for the slope
wetland and adjacent upland habitat conditions.

Wetland 7. Wetland 7 is a riverine wetland located within the utility corridor, west of the maintenance road, along
the bank of Stream 1. Wetland 7 has a PFO Cowardin habitat class composed of red alder with an understory of
salmonberry and piggyback-plant (Tolmiea menziesii). The wetland receives overbank flooding from Stream 1.
The presence of water-stained leaves and hydrogen sulfide odor suggest long periods of soil saturation within the
unit. The wetland is bordered by the maintenance road embankment in the utility corridor to the east (moderate
intensity land use), and relatively undisturbed habitat to the west (low intensity land use). Photographs 20 and 21
show the habitat conditions of the wetland.
Wetland 8. Wetland 8 is a riverine wetland located along Stream 1 and upstream of Wetland 7 on the east side of
the maintenance road embankment within the utility corridor. Wetland hydrology is supported by overbank flows
from Stream 1 and groundwater seeps. Wetland 8 and Stream 1 originate east of and outside of the trail
easement corridor. Dominant vegetation within the portion of Wetland 8 within the trail easement is salmonberry,
lady fern, and piggyback-plant. Wetland 8 has a PSS Cowardin class within the trail easement, and PFO habitat
to the east and outside of the easement. The unit is an average of 35-feet wide, and the stream is approximately
two feet wide. The upland buffer to the west of the unit is maintained and mowed within the utility corridor.
Relatively undisturbed land use extends to the east. Photographs 23 and 24 show the wetland unit associated
with Stream 1 and the upland buffer vegetation conditions adjacent to the wetland unit.
Wetlands 9-16. Wetlands 9 through 16 consist of multiple slope wetlands with PSS habitat interspersed with
uplands (e.g., mosaic) located north of Wetland 8 along the east and west sides of the maintenance road within
the utility corridor and trail easement. Wetlands 9 through 16 have been lumped together due to similar habitat
characteristics and functions per the 2014 Wetland Rating System for wetland/upland mosaics. Otak biologists
based the delineation on limits of observed ponding and hydrophytic vegetation within the topographic
depressions. The individual wetland areas are small (<0.1 acre individually) and supported by shallow
groundwater seeps and saturated soil conditions. The individual wetlands are located within 100 feet of each
other and meet the definition of regulated wetlands per JCC 18.22.710 despite being individually less than 0.1
acre in size. Wetland 15 is situated in a ditch along the east side of the maintenance road, but wetland conditions
are assumed to be naturally occurring due to the groundwater seeps upslope and downslope of the road.
Therefore, the wetland does not meet the definition of artificial per JCC 18.22.710. Dominant vegetation
throughout the wetlands consists of spiraea and common rush. The adjacent upland areas are vegetated with
salal, salmonberry and western swordfern. Buffer conditions include the disturbed utility corridor, forest land to the
east, and recently logged areas to the west. Photographs 28 through 33 show the individual slope wetlands that
make up the unit.
Wetland 17. Wetland 17 is a slope wetland located within the utility corridor and trail easement, west of the
maintenance road. The wetland is on a slope generally oriented east to west and south to north. Wetland 17
borders an auxiliary maintenance road to the west (Photograph 34 in Appendix E), and an upland berm to the
north that is situated between Wetlands 17 and 19. Wetland 17 has a Cowardin habitat class of PSS and a
vegetation community composed of spiraea and common rush. The unit is supported by shallow groundwater and
seeps, and has saturated soil conditions. Upland vegetation adjacent to the wetland unit is dominated by salal
and western swordfern.
Wetland 18. Wetland 18 is a depressional wetland located west of the auxiliary road along the western boundary
of the utility corridor and trail easement, west of Wetland 19. The Cowardin habitat class is PFO. The dominant
vegetation is Pacific willow which covers most of the wetland. Ponded water is present in the depression. The unit
is bordered by an upland berm to the west and a maintenance road to the east. Wetlands 17 and 18 are within the
wetland buffer to the southwest and northwest. Western swordfern is present in the upland area to the west. A
residential property is within 100-feet of the wetland to the west. Wetland 18 presumably overtops the auxiliary
road prism and overflows to Wetland 19 during precipitation or snow melt events. Photograph 35 shows ponding
and habitat conditions within Wetland 18.
Wetland 19. Wetland 19 is a depressional wetland located within the utility corridor and trail easement
underneath the overhead power lines. The wetland is bordered by maintenance roads along approximately 75
Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 10
Wetland and Stream Delineation Report Otak
percent of its boundary. The wetland is seasonally ponded and supports amphibian breeding habitat. In addition
to ponding, hydrogen sulfide odor was observed that indicates prolonged saturated soil conditions around the
edges of the ponded area. Wetland 19 includes PSS and PEM Cowardin habitat classes. Dominant plant species
include Pacific willow, red-stem dogwood (Cornus sericea), spiraea, and common rush. Photographs 36 and 37
show typical habitat conditions of the wetland unit.
Wetland 20. Wetland 20 is depressional wetland located along the north end of the utility corridor and trail
easement. The wetland receives surface water from Stream 3, which is then impounded by the maintenance road
embankment and infiltrates. Overflows in Wetland 3 outlet through a culvert underneath the road to a constructed
ditch outside of the trail easement and infiltrates in uplands. The Cowardin classes within the unit are PFO, PSS,
and PEM. Dominant vegetation includes red alder, spiraea, common rush, and small-fruited bulrush (Scirpus
microcarpus). Himalayan blackberry (Rubus armeniacus) and mixed grass species dominate the upland buffer to
the south. The wetland originates east of the study area and upslope along the Stream 3 corridor. Photographs 41
and 42 show the habitat conditions within the wetland unit.
3.2 Wetland Functions, Ratings, and Buffer Widths
Of the 20 individual wetlands delineated, several wetlands fall within a wetland/upland mosaic and are rated as a
single unit per guidance in the 2014 Wetland Rating System. A total of 13 rating forms were completed. Eight
wetland units are rated as Category III wetlands and five are rated as Category IV wetlands. Three Category IV
wetland units have an HGM designation of slope, and two are depressional. Six Category III wetlands are
depressional, and two are riverine. Wetland functions summaries are provided in Table 3-2, and wetland rating
forms are provided in Appendix D.
Generally, the wetlands provide low to moderate (scores of 4-6) water quality functions such as trapping and
removing pollutants locally and within the watershed. Wetlands provided low to moderate site potential for
hydrologic functions by storing water within the unit and having relatively small contributing basins. Slope
wetlands generally do not provide the same water storage functions as depressional wetlands and rated lower.
Hydrologic functions generally rated low to moderate (3-6) due to lack of pollutants in the surrounding landscape
and absence of flooding downgradient of the wetlands. Depressional wetlands scored higher than slope wetlands
due to characteristics that slow and retain surface water. Wetland habitat functions are moderate to high (5-8) due
to moderate interspersion of habitat types, and a relatively high connectivity to undisturbed habitat and low to
moderate land uses (e.g., forest land).
Standard wetland buffer widths are based on wetland category and characteristics, habitat scores, and intensity of
the impact of proposed adjacent land use per JCC 18.22.730. The majority of wetlands in the study area are
located adjacent to, or within easements associated with utility corridor land use. The proposed trail construction
will likely include a paved trail and will likely be constructed entirely within the utility corridor where maintenance
roads currently exist. The proposed land use is categorized as moderate intensity land use per JCC 18.22.730(6)
(Wetland Buffer Widths).
Wetland buffers range from 40 to 225 feet for Category III and IV wetlands for moderate impact buffer width
between 5-8 habitat scores. Throughout the project, buffers consist of moderately disturbed land within the utility
corridor easements, relatively undisturbed forested land outside of the easements, and rural residential land uses.
In general, the utility corridor is dominated by grass areas and scrub habitat from periodic maintenance, while the
adjacent forested area is composed of coniferous stands less than 30 years old with deciduous species along the
forest edges.
Wetland buffers along the southern end of the study area include recently (2016) logged land areas and relatively
undisturbed forest that extends south toward Anderson Lake State Park. The buffers associated with Wetland 1
and Wetland 2 are 110-feet wide and include recently logged land to the north, and forested land to the south.
Wetland 3 has a buffer width of 40-feet and includes recently logged areas and a small portion of Wetlands 2 and
4. The buffer of Wetland 4 is 225-feet wide and consists of logged land to the west, and relatively undisturbed
forested area to the east and south. The buffer of Wetland 4 overlaps Wetlands 2 and 3.

Along the north-south aligned utility corridor and trail easement, Wetlands 5 through 20 are located adjacent to
forested land and in most cases are within maintained area within the utility corridor. The 40-foot buffer
associated with Wetlands 5 and 6 overlaps a portion of the maintenance road to the west and forested land to the
east. Wetland 7 has a 110-foot buffer that extends west into forested land and east into the utility corridor.
Wetland 8 has a 225-foot buffer which encompasses a portion of the utility corridor and extends east into forested
land. Wetlands 9-16 are rated as a single unit and have a 40-foot buffer from the outer extent of each delineated
wetland polygon. The buffers include land primarily within the utility corridor. Wetland 17 has a 40-foot buffer that

situated within the disturbed utility corridor. Wetlands 18 and 19 have 60-foot buffers that include areas in the
utility corridor and forested area to the west. Wetland 20 has a 110-foot buffer that includes forest and meadow
habitats within and adjacent to the utility corridor and trail easement.
3.3 Fish and Wildlife Habitat Conservation Areas
3.3.1 Watercourses and Riparian Habitats
Three streams are present within the study area. Two streams were delineated within the utility corridor and trail
easements (Stream 1 and Stream 2), and one stream (Stream 3) was observed from the ROW and its boundaries
estimated using LiDAR and aerial ESRI imagery, east of the trail easement near Wetland 20.
Stream summaries are provided in Table 3-3. Stream classifications and riparian buffer widths were determined
per JCC 18.22.630(b) (Prescriptive FWHCA Buffers), and JCC 18.22.630(1) (Stream Buffers). Stream typing is
determined using the criteria in Washington Administrative Code (WAC) 222-16-030. WDNR mapped four
streams within the study area (Appendix B: Figure 5). Otak biologists identified stream presence at one of the four
mapped locations, in addition to two unmapped streams not listed on state or local resource mapping.

Stream 1 flows from east to west through Wetland 8 and two culverts under the existing maintenance roads within
the utility corridor. The stream daylights between the primary maintenance road and the secondary maintenance
road within the utility corridor, spanning approximately 25 feet before flowing into a culvert located under the
secondary maintenance road and discharging into Wetland 7. The stream is approximately 24 inches in width.
Stream 1 is mapped as a Type N (nonfish habitat) watercourse by the WDNR FPMAT. Type N streams are
categorized into perennial or seasonal streams per JCC 18.22.630 (Stream Buffers). Stream 1 has a seasonal
flow regime and is therefore typed Ns (nonfish, seasonal). Buffer widths are assigned based on the percent grade
(i.e., slope) of type Ns streams. The slope of Stream 1 is less than 20 percent and has a 50-foot buffer width. The
stream buffer includes forested areas to the east and west, and the maintenance road and disturbed utility
corridor. Photographs 20-27 show the flow path of Stream 1, associated wetlands (Wetlands 7 and 8), and buffer
conditions.
Stream 2 is approximately 12” in width and 40 feet long. The stream is fed by a groundwater seep emanating
along the hillslope, and flows at the surface for approximately 40 feet before infiltrating in an upland field. Stream
2 is not mapped by local or state mapping resources. Indicators of OHWM included gravel sorting, bed and bank,
scour, and surface water. Buffer vegetation includes a dense salmonberry community. Photograph 39 shows the
confined stream channel and buffer vegetation. A portion of the stream buffer is mowed and maintained.
Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 13
Wetland and Stream Delineation Report Otak
Stream 3 is located east of Wetland 20 and outside of the easement boundary. The stream discharges to Wetland
20 at the bottom of the hillside. The stream boundary is estimated using lidar imagery and observations made in
the field. Stream 4 is not identified by the WDNR FPMAT mapper. The stream is type Ns with less than 20
percent grade, resulting in a 50-foot buffer width per JCC 18.22.630. The stream buffer is composed of red alders
trees and salmonberry. Photograph 40 shows the general riparian habitat associated with the stream and typical
buffer conditions.
3.3.2 Fish and Wildlife Habitat Conservation Areas
Per the Washington Natural Heritage Program, no sensitive plant species or natural heritage features are
identified on the Washington Wetlands of High Conservation Value Map Viewer within the project vicinity (WDNR
2022a). No sensitive plant species were observed during the field survey in March 2022.
No designated habitats of local importance are present within the study area, including locally important species
or habitats per JCC 18.22.630(2) (Buffers for Other FWHCAs). The project occurs within Puget Sound Recovery
Domain for Puget Sound Chinook Salmon (DPS) and Puget Sound Steelhead (DPS) protected under the ESA
(NOAA 2022). However, no waterbodies within the study area are mapped for the presence of listed fish species
through WDFW PHS or SWIFD mapping. All streams within the study area are typed as non-fish habitat.
The USFWS IPaC tool lists the potential presence of five threatened federally listed species, one endangered
species, and one candidate species. The IPaC tool does not map any designated critical habitats within the study
area. WDFW PHS does not document these species or nests occurring within the study area. Otak biologists
visually surveyed for suitable habitat and presence of federally listed species in the easement corridor during the
field visit on March 2 through March 4, 2022. However, no listed species or suitable habitats were observed due
to recent logging activities, periodic maintenance activities (e.g., utility corridor), or other site disturbances.
Specifically, suitable habitat for marbled murrelet within and adjacent to the study area was assessed using
definitions of marbled murrelet habitat per USFWS Guidance for Identifying Marbled Murrelet Nest Trees in
Washington State (2012). The USFWS defines the range of nest trees in Washington as all areas within 55 miles
of marine waters. These trees must have the presence of platforms, sufficient cover, and other tree and forest
area characteristics. Nesting platforms are defined as “relatively flat surface[s] > 33 feet above the ground in the
live crown of a coniferous tree” (USFWS 2012). The width of the platform must be a minimum of four inches wide.
A single nesting platform can support a nest, and presence of these platforms can be condensed or dispersed
throughout the forest. Cover of the nest platforms must be present in order to provide chicks protection from
predation, and can consist of vertical or horizontal cover above or to the side of the nest.
Suitable nesting habitat was not observed within the study area. The study area is mostly located on or adjacent
to active forest lands or roadways. The age of the existing forest stands range from 17 to 32 years old along the
north-south aligned trail easement. Aerial imagery on Google Earth (2022) shows that a majority of the forested
utility corridor and surrounding areas was clear cut between 1990 and 2005. The existing forested stands do not
meet size criteria for platform widths in the study area. No deformities of branches were observed such as dwarf
mistletoe that would provide suitable nesting habitat.
3.4 Regulatory Summary
Wetlands and streams within the study area are assumed to be regulated by local, state, and federal agencies.
Four wetlands are assumed to be regulated by the USACE, and all wetlands are assumed to be regulated by
Ecology and the County. Streams onsite are assumed to be regulated by state (Ecology and WDFW) and local
(Jefferson County) agencies, whereas only Stream 1 is assumed ot be regulated by the USACE. Riparian buffers
are regulated by Jefferson County per JCC 18.22.630 (Protection Standards). Impacts to streams and their
buffers require prior authorization and coordination with regulatory agencies.
3.4.1 U.S. Army Corps of Engineers
The Environmental Protection Agency (EPA) and USACE regulate wetlands and other waters of the United States
(WOTUS) under Section 404 of the Clean Water Act (CWA). The agencies are currently interpreting WOTUS
Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 14
Wetland and Stream Delineation Report Otak
consistent with the pre-2015 regulatory regime (EPA 2021) per 40 CFR 230.3(s). The WOTUS definition includes
traditional navigable waters (TNW), wetlands adjacent to TNWs, non-navigable tributaries to TNWs [identified as
relatively permanent waters (RPWs) and non-RPWs), and wetlands that abut or have a significant nexus to such
tributaries. Discharge of fill material into these waterbodies is regulated under Section 404 and 401 of the CWA.
Puget Sound and Discover Bay are classified as a TNW. Stream 1 is classified a RPW because it is assumed to
flow continuously for at least three months out of the year and has a surface connection to Discovery Bay and
Puget Sound. Streams 2 and 3 do not appear to have a surface connection to a TNW, and therefore do not
appear to qualify as either RPWs or non-RPWs.
Wetlands 2, 3, 4, 6, 7, and 8 are assumed to be within federal jurisdiction under the CWA. Wetlands 2 and 3 are
assumed to have a hydrological connection to the outlet stream from Anderson Lake near Anderson Lake Road.
Wetland 4 is assumed to have a hydrological connection to Anderson Lake, which outlets at its southwest corner
to a tributary that discharges to Discovery Bay. Wetland 6 is located along a mapped drainage path that
presumably discharges to Discovery Bay. Wetland 7 and Wetland 8 are located adjacent to Stream 1, a RPW
which outflows to Discovery Bay.
Wetlands 1, 5, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 are assumed not to be regulated by the USACE
because the definition of WOTUS provided at 40 CFR 230.3(s) is not met. These wetlands are not adjacent to
TNWs, RPWs, or non-RPWs, and do not have a significant nexus to TNWs, RPW, and non-RPWs. Therefore,
these wetlands are not likely to significantly affect the chemical, physical, and biological integrity of downstream
navigable waters (Table 4-1 Federal Jurisdiction of Wetland and Streams in Study Area).

3.4.2 Washington State Department of Fish and Wildlife
WDFW requires issuance of a Hydraulic Permit Approval (HPA) prior to any activities that may directly or
indirectly affect streams or associated aquatic resources considered as waters of the state per the Regional Code
of Washington (RCW) 90.48.020. Construction in or near state waters that will “use, divert, obstruct, or change
the natural flow or bed of any of the salt of fresh waters in the state.” (RCW 77.55.011(11) require an HPA.
Streams 1, 2, and 3 are considered waters of the state and will require an HPA if they will be impacted. Activities
included in the Hydraulic Code Rules (Chapter 220-660 WAC) require an HPA.
3.4.3 Washington State Department of Ecology
Ecology regulates activities in wetlands and streams under Section 401 of the CWA through the Water Quality
Certification process. Ecology has authority over discharge into all wetlands and streams and can impose buffers
and compensatory mitigation for impacts per RCW 90.48 (Water Pollution Control Act) depending on the
proposed project and amount of impacts to aquatic resources. All wetlands in the study area assumed to be
regulated by Ecology.
3.4.4 Local Jurisdiction – Jefferson County
Wetland and riparian buffers are regulated by Jefferson County per JCC 18.22.700 (Wetlands) and JCC
18.22.600 (Fish and Wildlife Habitat Conservation Areas), respectively. Exemptions for non-federally regulated
Category IV wetlands do not apply to any of the wetlands on site per JCC 18.22.710 (3)(g) because all wetlands
score higher than 5 points for habitat functions based on the 2014 Wetland Rating System and they are in an
upland/wetland mosaic.

Web Soil Survey URL:
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Jefferson County Area, Washington
Survey Area Data: Version 20, Sep 1, 2021
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Jul 25, 2020—Nov
29, 2021
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

Wetland Rating System for Western WA: 2014 Update 3
Rating Form – Effective January 1, 2015
HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.

Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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
being rated
HGM class to
use in rating
Slope + Riverine Riverine
Slope + Depressional Depressional
Slope + Lake Fringe Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional
Depressional + Lake Fringe Depressional
Riverine + Lake Fringe Riverine
Salt Water Tidal Fringe and any other
class of freshwater wetland
Treat as
ESTUARINE
If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

Rating Form – Effective January 1, 2015
These questions apply to wetlands of all HGM classes.
HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
____Aquatic bed 4 structures or more: points = 4
____Emergent 3 structures: points = 2
____Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
____Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
____The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).
____Permanently flooded or inundated 4 or more types present: points = 3
____Seasonally flooded or inundated 3 types present: points = 2
____Occasionally flooded or inundated 2 types present: points = 1
____Saturated only 1 type present: points = 0
____Permanently flowing stream or river in, or adjacent to, the wetland
____Seasonally flowing stream in, or adjacent to, the wetland
____Lake Fringe wetland 2 points
____Freshwater tidal wetland 2 points
H 1.3. Richness of plant species
Count the number of plant species in the wetland that cover at least 10 ft2.
Different patches of the same species can be combined to meet the size threshold and you do not have to name
the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle
If you counted: > 19 species points = 2
5 - 19 species points = 1
< 5 species points = 0
H 1.4. Interspersion of habitats
Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or
the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you
have four or more plant classes or three classes and open water, the rating is always high.
None = 0 points Low = 1 point Moderate = 2 points
All three diagrams
in this row
are HIGH = 3points

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.
Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak
component is important (full descriptions in WDFW PHS report p. 158 – see web link above).
Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and

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.
Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and
Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report –
see web link on previous page).

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.
Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

Cat. I
Cat. II
SC 2.0. Wetlands of High Conservation Value (WHCV)
SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3
SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes = Category I No = Not a WHCV
SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV
SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website? Yes = Category I No = Not a WHCV
Cat. I
SC 3.0. Bogs
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key
below. If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or
more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2
SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep
over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or
pond? Yes – Go to SC 3.3 No = Is not a bog

NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.

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 some time 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 Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
W3
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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

Depressional + Riverine along stream
within boundary of depression
Depressional
Depressional + Lake Fringe Depressional
Riverine + Lake Fringe Riverine
Salt Water Tidal Fringe and any other
class of freshwater wetland
Treat as
ESTUARINE
If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

These questions apply to wetlands of all HGM classes.
HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
____Aquatic bed 4 structures or more: points = 4
____Emergent 3 structures: points = 2
____Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
____Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
____The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).
____Permanently flooded or inundated 4 or more types present: points = 3
____Seasonally flooded or inundated 3 types present: points = 2
____Occasionally flooded or inundated 2 types present: points = 1
____Saturated only 1 type present: points = 0
____Permanently flowing stream or river in, or adjacent to, the wetland
____Seasonally flowing stream in, or adjacent to, the wetland
____Lake Fringe wetland 2 points
____Freshwater tidal wetland 2 points
H 1.3. Richness of plant species
Count the number of plant species in the wetland that cover at least 10 ft2.
Different patches of the same species can be combined to meet the size threshold and you do not have to name
the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle
If you counted: > 19 species points = 2
5 - 19 species points = 1
< 5 species points = 0
H 1.4. Interspersion of habitats
Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or
the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you
have four or more plant classes or three classes and open water, the rating is always high.

http://wdfw.wa.gov/conservation/phs/list/)
Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: NOTE: This question is
independent of the land use between the wetland unit and the priority habitat.
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 (full descriptions in WDFW PHS report).

layered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha ) > 32 in (81 cm) 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.
Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak
component is important (full descriptions in WDFW PHS report p. 158 – see web link above).
Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and
terrestrial ecosystems which mutually influence each other.

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.
Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and
Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report –
see web link on previous page).
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.
Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

The dominant water regime is tidal,
Vegetated, and
With a salinity greater than 0.5 ppt Yes –Go to SC 1.1 No= Not an estuarine wetland
SC 1.1. Is the wetland within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area
Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332-30-151?
Yes = Category I No - Go to SC 1.2
Cat. I
SC 1.2. Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less
than 10% cover of non-native plant species. (If non-native species are Spartina, see page 25)
At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un-
mowed grassland.
The wetland has at least two of the following features: tidal channels, depressions with open water, or
contiguous freshwater wetlands. Yes = Category I No = Category II
Cat. I
Cat. II
SC 2.0. Wetlands of High Conservation Value (WHCV)
SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3
SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes = Category I No = Not a WHCV
SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV
SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website? Yes = Category I No = Not a WHCV
Cat. I
SC 3.0. Bogs
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key
below. If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or
more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2
SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep
over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or
pond? Yes – Go to SC 3.3 No = Is not a bog
SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30%
cover of plant species listed in Table 4? Yes = Is a Category I bog No – Go to SC 3.4
NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by
measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the
plant species in Table 4 are present, the wetland is a bog.
SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar,
western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
W4
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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

If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

____Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
____Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
____The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
5
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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
being rated
HGM class to
use in rating
Slope + Riverine Riverine
Slope + Depressional Depressional
Slope + Lake Fringe Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional
Depressional + Lake Fringe Depressional
Riverine + Lake Fringe Riverine
Salt Water Tidal Fringe and any other
class of freshwater wetland
Treat as
ESTUARINE
If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

CATEGORIZATION BASED ON SPECIAL CHARACTERISTICS
Wetland Type
Check off any criteria that apply to the wetland. Circle the category when the appropriate criteria are met.
Category
SC 1.0. Estuarine wetlands
Does the wetland meet the following criteria for Estuarine wetlands?
The dominant water regime is tidal,
Vegetated, and
With a salinity greater than 0.5 ppt Yes –Go to SC 1.1 No= Not an estuarine wetland
SC 1.1. Is the wetland within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area
Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332-30-151?
Yes = Category I No - Go to SC 1.2
Cat. I
SC 1.2. Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less
than 10% cover of non-native plant species. (If non-native species are Spartina, see page 25)
At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un-
mowed grassland.
The wetland has at least two of the following features: tidal channels, depressions with open water, or
contiguous freshwater wetlands. Yes = Category I No = Category II
Cat. I
Cat. II
SC 2.0. Wetlands of High Conservation Value (WHCV)
SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3
SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes = Category I No = Not a WHCV
SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV
SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website? Yes = Category I No = Not a WHCV
Cat. I
SC 3.0. Bogs
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key
below. If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or
more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2
SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep
over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or
pond? Yes – Go to SC 3.3 No = Is not a bog
SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30%
cover of plant species listed in Table 4? Yes = Is a Category I bog No – Go to SC 3.4
NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by
measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the
plant species in Table 4 are present, the wetland is a bog.
SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar,
western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the
species (or combination of species) listed in Table 4 provide more than 30% of the cover under the canopy?
Yes = Is a Category I bog No = Is not a bog

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.

Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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.

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.
Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

Rating Form – Effective January 1, 2015
HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.

Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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.

These questions apply to wetlands of all HGM classes.
HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
____Aquatic bed 4 structures or more: points = 4

Wetland Rating System for Western WA: 2014 Update 3
Rating Form – Effective January 1, 2015
HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
W8
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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

If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

be found, in: Washington Department of Fish and Wildlife. 2008. Priority Habitat and Species List. Olympia, Washington.
177 pp. http://wdfw.wa.gov/publications/00165/wdfw00165.pdf or access the list from here:
http://wdfw.wa.gov/conservation/phs/list/)
Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: NOTE: This question is
independent of the land use between the wetland unit and the priority habitat.
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 (full descriptions in WDFW PHS report).
Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock.
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) 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.
Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak
component is important (full descriptions in WDFW PHS report p. 158 – see web link above).
Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and
terrestrial ecosystems which mutually influence each other.
Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet
prairie (full descriptions in WDFW PHS report p. 161 – see web link above).
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.
Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and
Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report –
see web link on previous page).
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.
Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

CATEGORIZATION BASED ON SPECIAL CHARACTERISTICS
Wetland Type
Check off any criteria that apply to the wetland. Circle the category when the appropriate criteria are met.
Category
SC 1.0. Estuarine wetlands
Does the wetland meet the following criteria for Estuarine wetlands?
The dominant water regime is tidal,
Vegetated, and
With a salinity greater than 0.5 ppt Yes –Go to SC 1.1 No= Not an estuarine wetland
SC 1.1. Is the wetland within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area
Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332-30-151?
Yes = Category I No - Go to SC 1.2
Cat. I
SC 1.2. Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less
than 10% cover of non-native plant species. (If non-native species are Spartina, see page 25)
At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un-
mowed grassland.
The wetland has at least two of the following features: tidal channels, depressions with open water, or
contiguous freshwater wetlands. Yes = Category I No = Category II
Cat. I
Cat. II
SC 2.0. Wetlands of High Conservation Value (WHCV)
SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3
SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes = Category I No = Not a WHCV
SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV
SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website? Yes = Category I No = Not a WHCV
Cat. I
SC 3.0. Bogs
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key
below. If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or
more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2
SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep
over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or
pond? Yes – Go to SC 3.3 No = Is not a bog
SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30%
cover of plant species listed in Table 4? Yes = Is a Category I bog No – Go to SC 3.4
NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by
measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the
plant species in Table 4 are present, the wetland is a bog.
SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar,
western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the
species (or combination of species) listed in Table 4 provide more than 30% of the cover under the canopy?
Yes = Is a Category I bog No = Is not a bog

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.

Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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.

If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

These questions apply to wetlands of all HGM classes.
HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
____Aquatic bed 4 structures or more: points = 4
____Emergent 3 structures: points = 2
____Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
____Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
____The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).
____Permanently flooded or inundated 4 or more types present: points = 3
____Seasonally flooded or inundated 3 types present: points = 2
____Occasionally flooded or inundated 2 types present: points = 1
____Saturated only 1 type present: points = 0
____Permanently flowing stream or river in, or adjacent to, the wetland
____Seasonally flowing stream in, or adjacent to, the wetland
____Lake Fringe wetland 2 points
____Freshwater tidal wetland 2 points
H 1.3. Richness of plant species
Count the number of plant species in the wetland that cover at least 10 ft2.
Different patches of the same species can be combined to meet the size threshold and you do not have to name
the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle
If you counted: > 19 species points = 2
5 - 19 species points = 1
< 5 species points = 0
H 1.4. Interspersion of habitats
Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or
the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you
have four or more plant classes or three classes and open water, the rating is always high.
None = 0 points Low = 1 point Moderate = 2 points

be found, in: Washington Department of Fish and Wildlife. 2008. Priority Habitat and Species List. Olympia, Washington.
177 pp. http://wdfw.wa.gov/publications/00165/wdfw00165.pdf or access the list from here:
http://wdfw.wa.gov/conservation/phs/list/)
Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: NOTE: This question is
independent of the land use between the wetland unit and the priority habitat.
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 (full descriptions in WDFW PHS report).
Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock.

layered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha ) > 32 in (81 cm) 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.
Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak
component is important (full descriptions in WDFW PHS report p. 158 – see web link above).
Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and
terrestrial ecosystems which mutually influence each other.
Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet
prairie (full descriptions in WDFW PHS report p. 161 – see web link above).
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.
Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and
Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report –
see web link on previous page).
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.
Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

Yes = Category I No - Go to SC 1.2
Cat. I
SC 1.2. Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less
than 10% cover of non-native plant species. (If non-native species are Spartina, see page 25)
At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un-
mowed grassland.
The wetland has at least two of the following features: tidal channels, depressions with open water, or
contiguous freshwater wetlands. Yes = Category I No = Category II
Cat. I
Cat. II
SC 2.0. Wetlands of High Conservation Value (WHCV)
SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3
SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes = Category I No = Not a WHCV
SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV
SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website? Yes = Category I No = Not a WHCV
Cat. I
SC 3.0. Bogs
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key
below. If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or
more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2
SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep
over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or
pond? Yes – Go to SC 3.3 No = Is not a bog
SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30%
cover of plant species listed in Table 4? Yes = Is a Category I bog No – Go to SC 3.4
NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by
measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the
plant species in Table 4 are present, the wetland is a bog.
SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar,
western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the
species (or combination of species) listed in Table 4 provide more than 30% of the cover under the canopy?

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.

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 some time 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 Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
18
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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

If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

Does the wetland meet the following criteria for Estuarine wetlands?
The dominant water regime is tidal,
Vegetated, and
With a salinity greater than 0.5 ppt Yes –Go to SC 1.1 No= Not an estuarine wetland
SC 1.1. Is the wetland within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area
Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332-30-151?
Yes = Category I No - Go to SC 1.2
Cat. I
SC 1.2. Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less
than 10% cover of non-native plant species. (If non-native species are Spartina, see page 25)
At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un-
mowed grassland.
The wetland has at least two of the following features: tidal channels, depressions with open water, or
contiguous freshwater wetlands. Yes = Category I No = Category II
Cat. I
Cat. II
SC 2.0. Wetlands of High Conservation Value (WHCV)
SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3
SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes = Category I No = Not a WHCV
SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV
SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website? Yes = Category I No = Not a WHCV
Cat. I
SC 3.0. Bogs
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key
below. If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or
more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2
SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep
over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or
pond? Yes – Go to SC 3.3 No = Is not a bog
SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30%
cover of plant species listed in Table 4? Yes = Is a Category I bog No – Go to SC 3.4
NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by
measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the
plant species in Table 4 are present, the wetland is a bog.
SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar,
western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the
species (or combination of species) listed in Table 4 provide more than 30% of the cover under the canopy?
Yes = Is a Category I bog No = Is not a bog

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
W19
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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.

If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

These questions apply to wetlands of all HGM classes.
HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
____Aquatic bed 4 structures or more: points = 4
____Emergent 3 structures: points = 2
____Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
____Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
____The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).
____Permanently flooded or inundated 4 or more types present: points = 3
____Seasonally flooded or inundated 3 types present: points = 2
____Occasionally flooded or inundated 2 types present: points = 1
____Saturated only 1 type present: points = 0
____Permanently flowing stream or river in, or adjacent to, the wetland
____Seasonally flowing stream in, or adjacent to, the wetland
____Lake Fringe wetland 2 points
____Freshwater tidal wetland 2 points
H 1.3. Richness of plant species
Count the number of plant species in the wetland that cover at least 10 ft2.
Different patches of the same species can be combined to meet the size threshold and you do not have to name
the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle
If you counted: > 19 species points = 2
5 - 19 species points = 1
< 5 species points = 0
H 1.4. Interspersion of habitats
Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or
the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you
have four or more plant classes or three classes and open water, the rating is always high.
None = 0 points Low = 1 point Moderate = 2 points

HGM Classification of Wetlands in Western Washington
1. Are the water levels in the entire unit usually controlled by tides except during floods?
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) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – 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.
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.
20
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
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 some time 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
being rated
HGM class to
use in rating
Slope + Riverine Riverine
Slope + Depressional Depressional
Slope + Lake Fringe Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional
Depressional + Lake Fringe Depressional
Riverine + Lake Fringe Riverine
Salt Water Tidal Fringe and any other
class of freshwater wetland
Treat as
ESTUARINE
If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

Monroe Avenue NE Storm System Improvements; Renton, Washington
Wetland Scientist—Otak completed an alternatives analysis of a combination of stormwater
infiltration facilities and other strategies to prevent historic flooding along Monroe Avenue.
Additionally, water quality treatment will be provided for runoff as applicable. Otak provided
hydrologic and hydraulic modeling of the subbasin to estimate existing flows, assess the
capacity of the existing infiltration system, and size the proposed improvements. Otak also
developed stormwater, flow control, and water quality solutions for the urbanized 211- acre
subbasin in the Renton Highlands area. The improved stormwater conveyance system will
convey the 25- year peak flow rate and reduce the probability of roadway overtopping during
the 100- year event, thus reducing the risk of flooding along Monroe Avenue NE and adjacent
private properties. The considered water quality solutions included green stormwater
infrastructure like bioretention, compost-amended vegetated filter strip and biofiltration swale,
and bioswale. Zan conducted the site assessment for wetlands and wildlife habitats, prepared
the findings report, and completed the SEPA compliance documentation.
