East McEwan Prairie Road
Shelton,Washington
INTRODUCTION
The Wetland Corps has been authorized by Nathan Stout to perform a wetland delineation
at the property (designated forest land) owned by James Brix located off of East McEwan
Prairie Road in Shelton, Mason County, Washington, (Tax Identification Number32133-
34-00010). The delineation was performed on January 1" 2013 to identify wetlands,
streams and associated buffers that would be applicable to four adjacent parcels (Parcels
32133-40-90024, 32133-40-90023, 32133-40-90022 and 32133-40-90021) to the south,
owned by Nathan Stout.
The subject property is located in the SW 1/4 of Section 33, Township 21 North, Range 04
West WM (Figure 1 Vicinity Map). According to the Mason County Assessor, the parcel
is 300 acres in size. Given the intention of this study is to identify buffers that may extend
onto the properties adjacent to the southwest side of the property, the study area
encompasses southwestern 50 acres of the property.
For the purposes of federal, Washington State, and Mason County jurisdictional oversight,
this wetland delineation followed the methodology outlined in the Regional Supplement to
the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and
Coast Region (Version 2.0) U.S. Army Corps of Engineers May 2010. WAC 173-22-035
states delineations should be done according to this manual and supplements. The changes
became effective March 14, 2011. The sections below provide: (1) an introduction to the
site; (2)a description of methods used in the field delineation; and, (3)technical results.
GENERAL SITE CONDITIONS
The property is accessed via East McEwen Prairie Road, which makes up a portion of the
southern property boundary. East Mason Lake Road makes up a portion of the eastern
property boundary. The parcel is bordered to the north, east and west by residential parcels
of similar size and shape. The property is undeveloped, and contains no buildings or
structures. In general,topography within the study area is flat.
The ownership generally consists of a forested community of Douglas Fir (Pseudotsuga
menziesii, FACU, with an understory of salal (Gaultheria shallon, FACU) and swordfern
(Polystichum munitum, FACU). A small, seasonal stream drains within 100 feet north of

the properties owned by Nathan Stout. The stream is surrounded by dark, saturated surface
soils and hydrophytic wetland vegetation such as slough sedge (Carex obnupta, OBL) and
lady fern (Athyrium filix femina, FAC), meeting Department of Ecology criteria for a
regulated wetland.
METHODOLOGY
Consistent with procedures detailed in the Washington State Wetlands Identification and
Delineation Manual (Washington State Department of Ecology, 2011) (2011 Manual),
preliminary information was gathered on the project site prior to the field review and
delineation. General information sources included: 1974 United States Fish and Wildlife
Service (USFWS) National Wetland Inventory (NWI) maps, the Soil Survey of Mason
County Area, Washington (USDA, 1951), the Washington Department of Natural
Resources Water Resource Map,and Mason County's critical areas regulations.
Field Delineation
The methodology used for this wetland delineation was consistent with the technical
approaches articulated in the 2011 Manual. This document is the wetland delineation
manual that is used in determining wetland areas when applying state and local
government regulations under the Shoreline Management Act and the Growth
Management Act in Washington State.
The extent and location of suspect wetlands were determined during field work performed
on January 1 s, 2013. Field work was conducted under cloudy conditions with an ambient
temperature ranging between 30 and 35 degrees Fahrenheit. The time of year and recent
precipitation history were considered in assessing the extent of the suspect wetlands
presumed to exist on site.
Specific field methodology used in determining the extent and location of wetland areas
include:
1. As part of the initial project site reconnaissance, the site was walked to determine
the general extent and location of potential wetland areas;
2. Wetland and upland sample plots were established in the identified potential
wetland areas and in the adjacent upland area; and
3. Wetland boundaries were delineated with flagging by noting localized topography
and vegetation patterns and comparing parameters of hydrology, soil, and
vegetation with data collected at the wetland and upland sample plots.
The project area was investigated and data was collected at two sample plot locations.
Data was collected at two sample plot locations. Each sample plot included a data form
completed for a wetland area and a form completed for the corresponding upland area.

BACKGROUND INFORMATION
Mason County Soil Survey
The soil survey of Mason County indicates three onsite soil types,(USDA, 1951):
Grove gravelly sandy loam, 0 to 5 percent slopes. (Gh):This soil occupies nearly level
out-wash plain. The Grove series consists of somewhat excessivelydrained,reddish-brown
gravelly soils. It occupies the large glacial outwash plains. The Grove soils have developed
from Vashon glacial drift, modified considerably by inclusions of local basaltic rock and
mixed material from the Olympic Mountain glaciers. The rainfall ranges from 60 to 100
inches a year. The vegetation is coniferous forest, with an understory dominated by the
lower growing mosses, kinnikinnick, and snowberry, and these mixed with huckleberry,
salal, and Oregon-grape. The droughtresistant manzanita is especially- common on the
Grove soils. The cover is not so profuse nor so rank as that on the adjacent Shelton and
Hoodsport soils. Logged areas restock slowly to Douglas-fir, and some pure stands of
lodgepole pine are on these soils. The Grove soils occur in the western part of the county,
in association with the Shelton and Hoodsport soils. Grove soils differ front the Everett
soils farther east in their parent material and in having redder surface soil and subsoil.
McKenna gravelly loam, 0 to 3 percent slopes (Mc).This soil occurs as small scattered
areas.The McKenna series consists of poorly drained, very dark, gravelly soils in
depressions and along natural drainageways. They have developed in Vashon glacial drift,
under rainfall that ranges from 45 to 60 inches a year. The vegetation consists of deciduous
trees and shrubs, sedges, reeds, spirea, and wild rose, with occasional thickets of quaking
aspen and Oregon-oak. McKenna soils occur mainly in association with the Alderwood
and Everett soils and only rarely with the Grove or Shelton soils. McKenna soils differ
from the Norma and Bellingham soils in having very gravelly subsoils and substrata. They
are much darker colored than the Koch soils. The Deckerville soils, which closely
resemble the McKenna, have developed from more basic parent material.
Carstairs gravelly loam, 0 to 5 percent slopes (Ca).-- The surface soil is a friable, fluffy,
very dark gray gravelly loam, about 7 inches thick. The Carstairs series consists of very
dark, excessively drained soils. They occupy the nearly treeless outwash plains in the
southwestern part of the county (fig. 3). In position and parent material, they are similar to
the Grove soils. Carstairs soils have developed from basic parent material and under
rainfall that ranges front 60 to 90 inches a year. The native vegetation consists of grass,
kinnikinnick, ferns, moss, and low shrubs. Although the soil is surrounded by dense
forests, it has no overstory, except for a few lodgepole pines, Douglas-firs, and clumps of
Oregon-oak. Carstairs soils are friable, shot free, gravelly, porous, and droughty. They
resemble the Grove soils in being porous, droughty, sand gravelly. They are finer textured
than the Spanaway soils (not mapped in Mason County) and grade more gradually to the
very loose and porous gravelly subsoil and substratum.

The Mason Soil Survey map is shown in Figure 4.
National Wetlands Inventory
The USFWS NWI map (online wetlands mapper) shows a portion of the subject wetland
identified by the NWI within the approximate site location. The wetland is categorized by
the Cowardin classification system as [P] Palustrine [FO] Forested [1] [C] Seasonally
flooded.
Department of Natural Resources Water Resource Map
The Department of Natural Resources Water Resource Map shows no streams in the
vicinity of the subject parcel (See Figure 5. WA DNR Water Resource Map). The nearest
stream is mapped approximately 300 feet south of the subject property. The identified
stream located approximately 100 feet north of the parcels owned by Nathan Stout, drains
between two extensive wetland systems located northeast and northwest of the study area
(See Figure 3. NWI Map). Based on aerial photos from the Mason County GIS Mapping
Tool (see photo on page 5, below), the identified channel does not appear to be
hydrologically connected to the mapped drainage.
WETLAND DELINEATION RESULTS
One riverine wetland was identified within 100 feet north of the parcels owned by Nathan
Stout. The wetland is located in the lowest point in general topography and receives
hydrology primarily from overbank flooding from the identified seasonal stream
(discussed below), coupled with subsurface hydrology from a high water table. In
addition,the wetland receives seasonal surface runoff from surrounding topography.
The wetland is narrow and elongated in shape, occupying a total area of approximately 1.5
acres. The wetland hydrologically connects two extensive wetland systems, located
approximately one quarter mile northwest of the study area, and east of East Mason Lake
Road (See Figure 3. NWI Map and aerial photo, below). The subject wetland is
hydrogeorphically classified as a Riverine wetland, given the dominant hydrology regime
is supported by overbank flooding from the stream channel. The larger wetland systems
beyond the subject Riverine wetland are classified as a Depressional wetland systems
located outside of the study area and do not affect the properties owned by Nathan Stout.
The subject stream provides an unconstricted surface water outlet at the southern end of the
large, Depressional wetland system to the northwest.

Photo 1. Bright green line represents wetland/stream complex,connecting two wetland systems
mapped by the NWI,outlined in striped blue. This photo is adapted from the Mason County GIS
Mapping Tool.
The wetland boundary was identified primarily by the abrupt transition from upland
vegetation such as salal (Gaultheria shallop, FACU) and swordforn (Polystichum
munitum, FACU) to facultative and obligate wetland vegetation, primarily slough sedge
(Carex obnupta, OBL). The presence of facultative wetland vegetation in congruence with
topography patterns and positive wetland hydrology indicators was used to identify the
wetland boundary.
Vegetation
The wetland contains an overstory of red alder (Alnus rubra, FAQ and western red cedar
(Thuja plicata, FAQ with various willow species (Salix sp.). The understory consists of
lady fern (Athyrium filix femina, FAQ and spires (Spiraea douglasii, FACW). Wetland
vegetation is indicated by hydrophytic vegetation FAC and FACW dominating over 50
percent of the vegetation community in wetland data plots.
The upland vegetation adjacent to the wetland area is comprised of an overstory primarily
consisting of Douglas fir (Pseudotsuga menziesii, FACU), with an associated understory
consisting of salal (Gaultheria shallon, FACU), evergreen huckleberry (Vaccinium
ovatum, FACU) and swordfern (Polystichum munitum, FACU). Hydophytic vegetation
occupies less than 50 percent of the vegetative community in upland data plots.
Soils
The profiles within the test pits consisted of a single layer profile consisting of silt loam to
12 inches deep with matrix chroma 10YR 3/1 and 10YR 2/1. Wetland hydric soils are
indicated by a thick, dark, surface on the surface of the soil and the presence of muck
within the loamy mineral soil. In addition, the soil consists of a low-chroma (equaling
one)in all wetland test pits.
The soil profiles observed in known upland test pits were consistent with the mapped soil
type, Grove gravelly sandy loam (Gh). Upland test pits exhibited a two-layer soil profile.
The upper layer consists of gravelly sandy loam approximately eight to ten inches deep of

matrix chroma 1 OYR 3/3. The lower profile contained less gravel with a matrix chroma of
10YR 6/3. No hydric soil indicators were present in upland soil test pits.
Hydrology
Wetland hydrology is indicated by FAC-neutral vegetation, drainage patterns, the wetland
is in the lowest point in general landscape topography, stunted or stressed plants growing
within the wetland, oxidized rhizospheres among living root channels, and water stained
leaves. In addition, the sample plots within the wetland area revealed inundation up to
eight inches, free water in the test pits at an four inch depth and soil saturation to the
surface.
Upland test pits showed no indicators of wetland hydrology.
STREAM ANALYSIS
A seasonal channel was identified within 100 feet north of the parcels owned by Nathan
Stout. The channel contains sorted gravels and a pool riffle complex, meeting WAC
16.222.030 criteria for a regulated channel. Based on Mason County Aerial Photos from
2011 (see below) coupled with information from the National Wetlands Inventory maps
(Figure 2. NWI Map), the stream appears to originate from the extensive depressional
wetland system located approximately one quarter mile northwest of the study area. The
stream drains east off the property,through a culvert under East Mason Lake Road. Based
on the aerial photo and NWI maps, the stream drains into a depressional wetland system
east of the property.
The identified channel draining within the above described riverine wetland does not meet
criteria for supporting fishbearing habitat, because the channel width is less than 2 feet, on
average, according to WAC 16.222.031. Therefore, this channel is regulated as a type Ns
stream according to Section 17.01.110 of the Mason County Resource Ordinance.
According to Section 17.01.110 of the Mason County Resource Ordinance, Type Ns
streams in Mason County require a buffer of 75 feet with an additional 15-foot building
setback.
WETLAND EVALUATION
The wetland is classified as a Riverine wetland per Washington State Wetland Rating
System for Western Washington (Hruby 2004). Based on functional attributes associated
with the wetland including habitat, water quality, and hydrology functions, it has been
rated as a Category II wetland, scoring 63 points on the state rating form. The score for
water quality functions in this wetland is 12, hydrological functions scored 26, and the
score for habitat functions is 25 (see Appendix C for rating form). According to Table
17.01.070 E of the Mason County Resource Ordinance, the base buffer width for Category
II Wetlands scoring between 20 and 28 points in habitat function is 70 feet with an
additional 15-foot building setback within parcels intended for Low Impact Land Use.
Low Impact Land Use is described in Table 17.07.070 B of the Mason County Resource

Ordinance as parcels designated for forestry, open space (low-intensity such as passive
recreation and natural resources preservation, minor transportation improvements. Given
that the wetland is situated within a parcel designated as forest land, the wetland is
assigned the buffer within associated with low-impact land-use.
SUMMARY
This wetland report documents the presence of a wetland meeting criteria for a Category II
Wetland. According to the Mason County Resource Ordinance,the wetland requires a 70-
foot buffer with additional 15-foot building setback for the existing land use. The wetland
surrounds a channel meeting criteria for a type Ns (Seasonal, nonfishbearing) stream.
Type Ns streams in Mason County are regulated with a 75-foot buffer with an additional
15-foot building setback. See Figure 2. Site Map for the approximate location of the
wetland, stream and associated buffers.

Onsite Soil Conditions based on Mason County Soil Survey
Subject Site Soils:
Grove gravelly sandy loam, 0 to 5 percent slopes. (Gh):This soil occupies nearly level out-wash plain. The Grove series
consists of somewhat excessivelydrained,reddish-brown gravelly soils.It occupies the large glacial outwash plains.The Grove
soils have developed from Vashon glacial drift,modified considerably by inclusions of local basaltic rock and mixed material

and Hoodsport soils. Grove soils differ front the Everett soils farther east in their parent material and in having redder surface
soil and subsoil.
McKenna gravelly loam, 0 to 3 percent slopes (Mc).This soil occurs as small scattered areas.The McKenna series consists
of poorly drained, very dark, gravelly soils in depressions and along natural drainageways. They have developed in Vashon
glacial drift, under rainfall that ranges from 45 to 60 inches a year. The vegetation consists of deciduous trees and shrubs,
sedges,reeds,spirea,and wild rose,with occasional thickets of quaking aspen and Oregon-oak.McKenna soils occur mainly in
association with the Alderwood and Everett soils and only rarely with the Grove or Shelton soils. McKenna soils differ from
the Norma and Bellingham soils in having very gravelly subsoils and substrata. They are much darker colored than the Koch
soils.The Deckerville soils,which closely resemble the McKenna,have developed from more basic parent material.
Carstairs gravelly loam,0 to 5 percent slopes(Ca).—The surface soil is a friable,fluffy,very dark gray gravelly loam,about
7 inches thick. The Carstairs series consists of very dark, excessively drained soils. They occupy the nearly treeless outwash
plains in the southwestern part of the county (fig. 3). In position and parent material, they are similar to the Grove soils.
Carstairs soils have developed from basic parent material and under rainfall that ranges front 60 to 90 inches a year.The native
vegetation consists of grass,kinnikinnick,ferns,moss,and low shrubs.Although the soil is surrounded by dense forests, it has
no overstory, except for a few lodgepole pines, Douglas-firs, and clumps of Oregon-oak. Carstairs soils are friable, shot free,
gravelly, porous, and droughty. They resemble the Grove soils in being porous, droughty, sand gravelly. They are finer
textured than the Spanaway soils (not mapped in Mason County) and grade more gradually to the very loose and porous
gravelly subsoil and substratum.

APPENDIX B
Soil Survey Text
GROVE SERIES
The Grove series consists of somewhat excessively
drained,reddish-brown gravelly soils. It occupies the large
glacial outwash plains. The Grove soils have developed from
Vashon glacial drift,modified considerably by inclusions of
local basaltic rock and mixed material from the Olympic
Mountain glaciers. The rainfall ranges from 60 to 100
inches a year. The vegetation is coniferous forest, with an
understory dominated by the lower growing mosses,
kinnikinnick, and snowberry, and these mixed with
huckleberry, salal,and Oregon-grape. The droughtresistant
manzanita is especially- common on the Grove soils.
The cover is not so profuse nor so rank as that on the
adjacent Shelton and Hoodsport soils. Logged areas
restock slowly to Douglas-fir, and some pure stands of
lodgepole pine are on these soils.
The Grove soils occur in the western part of the
county, in association with the Shelton and Hoodsport soils.
Grove soils differ front the Everett soils farther east in their
parent material and in having redder surface soil and
subsoil.
Grove gravelly sandy loam,0 to 5 percent slopes
(Gh):This soil occupies nearly level out-wash plain.
In forested areas there is a 1-to 2-inch layer of
needles, leaves,twigs,roots, and moss. The lower part is
moderately decomposed and very dark grayish brown.
The surface soil consists of reddish-brown, gravelly
sandy loam, 6 inches thick. It is very friable, is single
grained, and contains a few small,round shot. The upper
part of this layer contains a few firm, irregular,more
reddish aggregates. The next layer extends to depths
ranging from 12 to 14 inches. It is similar to the surface
soil,except that it is more gravelly,contains less shot, and
the gravel is stained and coated with dark reddish-brown
fine material.
The subsoil is a light-brown,very gravelly loamy sand. It
is loose, is single grained, and contains no shot. At
depths ranging from 24 to 32 inches,the subsoil grades
to the substratum of loose gravel, cobbles,and sand. The
dominant colors are gray. grayish brown, yellowish brown,
and light brown. Much of the gravel is highly stained with
nearly black and reddish-brown material. In places the
upper 24 inches of the substratum is compact or weakly
cemented.
Included with this soil are about 250 acres occurring
on gently sloping fans, colluvial slopes,and terraces. The
parent material of the included soils is a mixture of local
basic igneous rock and mixed glacial material. The profile
is similar to that of Grove gravelly sandy loam, 0 to 5
percent slopes, but it differs in being brown and yellowish
brown,more variable in texture and in degree of
stratification, and in containing much angular and
subangular gravel.
This soil is strongly to medium acid and less acid with
depth. Surface runoff is very slow because of the rapid
permeability of the soil and the smooth topography.
Use and suitability.-Except for a very small acreage
in farms producing mainly for the farm household,this
soil is in forest, a use for which it is best suited. Because
of droughtiness and low fertility,it is not suitable for
hay or pasture. In suitability,this soil is similar to the
Everett gravelly sandy loam, 0 to 5 percent slopes,
except that it is in classes 3 and 4 for Douglas-fir,
partly because of the higher rainfall. Areas in young
Douglas-fir are managed for Christmas trees. The soil is in
capability subclass Vis.
McKENNA SERIES
The McKenna series consists of poorly drained,very dark,
gravelly soils in depressions and along natural drainageways.
They have developed in Vashon glacial drift,under rainfall
that ranges from 45 to 60 inches a year.
The vegetation consists of deciduous trees and shrubs,
sedges,reeds, spirea, and wild rose,with occasional thickets
of quaking aspen and Oregon-oak. McKenna
soils occur mainly in association with the Alderwood and
Everett soils and only rarely with the Grove or Shelton soils.
McKenna soils differ from the Norma and Bellingham soils in
having very gravelly subsoils and substrata. They are much
darker colored than the Koch soils. The Deckerville soils,
which closely resemble the McKenna,have developed from
more basic parent material.
McKenna gravelly loam,0 to 3 percent slopes (Mc).This
soil occurs as small scattered areas. The surface soil is
friable and granular,dark-gray(nearly black when moist)
gravelly loam that is high in organic matter. Below this,to
depths of 10 to 15 inches, is firm, dark grayish-brown very
gravelly loam or gravelly clay loam that has a weak,
subangular blocky structure and is moderately high in
organic matter. This grades to firm,massive subsoil
consisting of light brownish-gray very gravelly loamy sand.
The substratum begins at depths of 24 to 30 inches and
consists of slightly to moderately compact,olive-brown and palebrown
coarse gravel and sand that is faintly mottled and
stained.
In many areas there is a thin,highly organic silty
layer on the surface. The soil is medium acid to strongly acid
in all layers. Gravel prevents cultivation. The soil is wet most
of the year but dries rapidly in summer.
Use and suitability.-Nearly all this soil is in natural
cover. A few areas have been cleared for pasture and
grazing. The narrow areas of this soil, and of other McKenna
soils,provide green pastures after those on surrounding
upland soils have dried.
This soil is in capability subclass IVw; it is poor for
evergreen and deciduous trees.
CARSTAIRS SERIES
The Carstairs series consists of very dark, excessively
drained soils. They occupy the nearly treeless outwash
plains in the southwestern part of the county(fig. 3).
In position and parent material,they are similar to the
Grove soils. Carstairs soils have developed from basic
parent material and under rainfall that ranges front 60 to
90 inches a year. The native vegetation consists of grass,
kinnikinnick, ferns,moss,and low shrubs. Although the
soil is surrounded by dense forests, it has no overstory,
except for a few lodgepole pines,Douglas-firs,and clumps
of Oregon-oak.
Carstairs soils are friable, shot free, gravelly,porous,
and droughty. They resemble the Grove soils in being
porous, droughty, sand gravelly. They are finer textured
than the Spanaway soils(not mapped in Mason County)
and grade more gradually to the very loose and porous
gravelly subsoil and substratum.
Carstairs gravelly loam,0 to 5 percent slopes (Ca).--
The surface soil is a friable, fluffy,very dark gray
gravelly loam, about 7 inches thick. It has a weak, fine,
granular structure; contains no shot; and,when moist, is
nearly black or very dark brown. The subsurface layer,
between depths of 7 and 15 inches, is a friable, darkbrown
gravelly loam. It has a very weak, fine, granular
structure and contains more gravel than the surface layer.
The subsoil, extending to a depth of 25 inches,is a very
friable,brown gravelly sandy loam. It is single grained
Figure 3.-The prairie is on Carstairs gravelly loam, 0 to 5 percent
slopes. The forest in background is on Grove gravelly sandy loam, 0 l
to 5 percent slopes.
and, in places, is weakly compact. The gravel is stained with
reddish brown and yellow. Below 25 inches is the substratum,
which consists of loose, stratified,multicolored sandy gravel
containing many cobbles and a few stones. Manganese and
iron stains are on the surface of some of the stones.
This soil has a few slopes greater than 5 percent. The
depth to the substratum ranges from 25 to 50 inches.
In a few areas the solum contains small amounts of
gravel and the surface soil is a sandy loam that is more
coarse at a greater depth. At a depth of 30 inches,the
texture grades to a loamy sand, or to sand.Near the surface,
the soil is very strongly acid,but the subsurface layer
is medium acid.
Use and suitability.-This soil is used mainly for pasture.
I t is too droughty and low in fertility for most cultivated
crops. Part of the acreage is used for building sites and an
airport. Small acreages are used for hay,pasture, and
small grains. Yields are low and crop failures are frequent.
This soil is in capability subclass VIs and in site
classes 3 and 4 for Douglas-fir.

Classification of Vegetated Wetlands for Western Washington
If the hydrologic criteria listed in each question do not apply to the entire unit being rated,you probably have a unit with
multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.
1. Are the water levels in the entire unit usually controlled by tides(i.e. except during floods)?
®NO—go to 2 ❑YES—the wetland class is Tidal Fringe
If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)?
❑ YES—Freshwater Tidal Fringe ❑ NO—Saltwater Tidal Fringe(Estuarine)
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Rivenne wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions,and
this separation is being kept in this revision. To maintain consistency between editions,the term"Estuarine"wetland is kept. Please
note,however,that the characteristics that define Category I and H estuarine wetlands have changed(see p. ).
2. The entire wetland unit is flat and precipitation is 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 meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water(without any vegetation on
the surface)where at least 20 acres(8ha)in size;
❑At least 30%of the open water area is deeper than 6.6(2 m)?
®NO—go to 4 ❑ YES—The wetland class is Lake-fringe(Lacustrine Fringe)
4. Does the entire wetland 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?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually<3 ft diameter and less than I foot deep).
®NO—go to 5 ❑YES—The wetland class is Slope
5. Does the entire wetland 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 two years.
NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding..
❑NO—go to 6 ® YES—The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface,at some time of
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 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 REGROES 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 your wetland 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 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 De ressional
Depressional+Lake-fringe Depression I
Salt Water Tidal Fringe and any other class of Treat as ESTUARINE under wetlands with special
freshwater wetland characteristics
If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes
within a wetland boundary, classify the wetland as Depressional for the rating.

❑YES =Category I ❑ NO=Category II Cat. I
❑The wetland is relatively undisturbed(has no diking,ditching,filling,cultivation,grazing,and has ❑
less than 10%cover of non-native plant species. If the non-native Spartina spp,.are only species Cat.II
that cover more than 10%of the wetland,then the wetland should be given a dual rating(I/II). ❑
The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh
with native species would be a Category 1. Do not,however,exclude the area of Spartina in Dual
determining the size threshold of 1 acre.
❑At least 3/4 of the landward edge of the wetland has a 100 ft.buffer of shrub,forest,or un-grazed or Rating
un-mowed grassland 1/II
❑The wetland has at least 2 of the following features: tidal channels,depressions with open water,or ❑
contiguous freshwater wetlands.
SC2 Natural Heritage Wetlands (seep. 87)
Natural Heritage wetlands have been identified by the Washington Natural Heritage Program/DNR as
either high quality undisturbed wetlands or wetlands that support state Threatened,Endangered,or
Sensitive plant species.
SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a natural heritage wetland? (This
question is used to screen out most sites before you need to contact WNHP/DNR.)
® S/T/R information from Appendix D ®or accessed from WNHP/DNR web site
❑YES Contact WNHP/DNR(see p. 79)and go to SC 2.2 ®NO
SC 2.2 Has DNR identified the wetland as a high quality undisturbed wetland or as a site with state threatened Cat I
or endangered plant species? ❑
❑YES =Category 1 ®NO not a Heritage Wetland
SC3 Bogs(seep. 87)
Does the wetland(or any part of the unit)meet both the criteria for soils and vegetation in bogs? Use
the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the
wetland based on its function.
1. Does the unit have organic soil horizons(i.e.layers of organic soil),either peats or mucks,that
compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to
identify organic soils)? ❑YES=go to question 3 ® NO=go to question 2
2. Does the wetland have organic soils,either peats or mucks that are less than 16 inches deep over
bedrock,or an impermeable hardpan such as clay or volcanic ash,or that are floating on a lake or
pond? ❑YES=go to question 3 ® NO=is not a bog for purpose of rating
3. Does the unit have more than 70%cover of mosses at ground level,AND other plants,if present,
consist of the"bog"species listed in Table 3 as a significant component of the vegetation(more
than 30%of the total shrub and herbaceous cover consists of species in Table 3)?
❑YES=Is a bog for purpose of rating ❑ NO=go to question 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"deep. If the pH is
less than 5.0 and the"bog"plant species in Table 3 are present,the wetland is a bog.
4. Is the unit forested(>30%cover)with sitka spruce,subalpine fir,western red cedar,western
hemlock,lodgepole pine,quaking aspen,Englemann's spruce,or western white pine.WITH any of
the species(or combination of species)on the bog species plant list in Table 3 as a significant
component of the ground cover(> 30%coverage of the total shrub/herbaceous cover)? Cat.I

layered canopy with occasional small openings;with at least 8 trees/acre(20 trees/hectare)that are
at least 200 years of age OR have a diameter at breast height(dbh)of 32 inches(81 cm or more).
NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees
in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW
criterion is and"OR"so old-growth forests do not necessarily have to have trees of this diameter.
❑Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80—200 years old
OR have an average diameters(dbh)exceeding 21 inches(53 cm);crown cover may be less than
