LIZOTTE WETLAND DELINEATION REPORT
4203 East Grapeview Loop Road
Grapeview, WA
INTRODUCTION
The Wetland Corps has been authorized by the Bigi Lizotte to perform a wetland
delineation at the above referenced property located in Grapeview, Mason County,
Washington, (Tax Identification Number 121082290120). The delineation was
performed to identify wetlands and associated buffers within or adjacent to the parcel.
The delineation was completed on March 14', 2008.
The subject property is located in the NW '/4 of Section 8, Township 21 North, Range 01
West WM(Figure 1 Vicinity Map). The parcel is 4 acres in size.
For the purposes of federal, Washington State, and Mason County jurisdictional
oversight, methodology used for the wetland delineation is consistent with the wetland
definition provided in paragraph 25a of the Washington State Wetlands Identification and
Delineation Manual (Washington State Department of Ecology, 1997). 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 subject parcel is surrounded to the east, north, and west by undeveloped by parcels,
and to the south by a smaller ownership with an existing SFR, and also by Grapeview
Loop Road. A road grade accesses the parcel from Grapeview Loop Road, extending
toward the northeastern portion of the property, where development is proposed.
Vegetation within the majority of the parcel generally consists of an overstory of Douglas
fir, western red cedar and western hemlock, with an understory of salal, swordfern, holly
and Oregon grape.
The property contains undulating topography, generally sloping down toward two
wetlands within the east and west sides of the property. The eastern wetland is in close
proximity,but does not appear to encroach within the property boundary. This wetland is
characterized by a community of salmonberry, slough sedge, and piggy back plant. The
western wetland occupies the western portion of the parcel, and is characterized by a
similar community of salmonberry and slough sedge, but also contains deer fern and an
overstory of red alder and western red cedar. The western wetland appears to be the

headwater to a channel, mapped by the DNR as a fishbearing channel, draining southerly
into Pickering Passage, located approximately 500 feet south of the subject property (See
Figure 5. WA DNR Map).
METHODOLOGY
Review of Existing Information
Consistent with procedures detailed in the Washington State Wetlands Identification and
Delineation Manual (Washington State Department of Ecology, 1997) (1997 Manual),
preliminary information was gathered on the project site prior to the field review and
delineation. General information sources included: United States Geological Service
(USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS)
National Wetland Inventory (NWI) maps, the Soil Survey of Mason County Area,
Washington (USDA, 1951), and Mason County's critical areas regulations.
Field Delineation
Methodology used for wetland delineation was consistent with the technical approaches
articulated in the 1997 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 March 13"', 2008. Field work was conducted under cloudy skies with an
ambient temperature ranging between 50 and 60 degrees Fahrenheit. The time of year
and recent precipitation history were considered in assessing the extent of the suspect
wetland 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 four sample plot locations.
Data collected at each sample plot were entered onto a Routine Wetland Determination
Data Form (Washington State Department of Ecology 1997). Copies of data forms for
each sample plot are provided in Appendix A.

BACKGROUND INFORMATION
Mason County Soil Survey
The soil survey of Mason County indicates two onsite soil types, (USDA, 1951):
Ab- Alderwood gravelly sandy loam, 5 to 15 percent slopes The Alderwood series
consists of brown, well-drained, upland soils. They have developed from mixed gravelly
glacial till dominated by acid igneous rock. The imbedded gravel is mainly granite and
quartzite. Rainfall is 45 to 60 inches a year. The native vegetation is a dense forest
consisting almost entirely of Douglas-fir and a dense understory of salal, Oregon-grape,
vine maple, and huckleberry. Northeast of the Hood Canal the understory is mainly
rhododendron. Alderwood soils occupy the extensive rolling glacial moraines, and they
are the dominant soils in the eastern part of the county. The Alderwood soils are
associated with the somewhat excessively drained Everett and Indianola soils and with
the moderately well drained Kitsap soils. Shelton and Hoodsport soils differ from the
Alderwood soils in that they have developed under high rainfall and from glacial till
having a much higher content of basic igneous rock. The Alderwood gravelly sandy
loam, 5 to 15 percent slopes (Ab) is the most extensive, soil of the Alderwood series. It
occupies undulating to rolling moraines.
Bellingham silty clay loam, 0 to 3 percent slopes(Be).-The Bellingham series consists of
poorly drained, very dark gray silty soils. They occupy upland depressions and glacial
like basins. They have developed from glacial materials under rainfall ranging from 4 to
60 inches per year. The native vegetation is a dense forest of alder, maple, willow, cedar,
and an occasional spruce and aspen. Under the forest is spirea and a dense growth of wild
rose, sedges, and watertolerant grasses and shrubs. Bellingham soils are medium acid and
high in organic matter. They are associated with the Kitsap and Cloquallum soils and
with other glacial soils of the uplands Bellingham silty clay loam, 0 to 3 percent slopes
(Be).-Most of this soil is on Squaxin Island and on other islands off Pickering Passage. It
is closely associated with Bellingham silt loam, 0 to 3 percent slopes, but differs from it
in having finer textured surface soil and upper subsoil.
A more detailed soil description can be found in Appendix B Mason Soil Survey Text.
The Mason Soil Survey map is shown in Figure 4.
National Wetlands Inventory
The USFWS NWI map (online wetlands mapper) shows no wetlands mapped within the
approximate parcel location. The nearest wetland is mapped approximately 0.7 mile
northeast of the parcel. (Figure 3. National Wetland Inventory Map).
Department of Natural Resources Water Resource
The Department of Natural Resources Water Resource Map shows the identified stream
west of the subject parcel. The stream is classified by the DNR as a type "F" (F =
fishbearing) stream. According to the Mason County Aerial Photo (2005), the stream

Photo 1. Wetland B,within property.
The portion of each wetland within 150 feet of the development zone are flagged with
pink ribbon labeled WETLAND DELINEATION (See Figure 2. Site Map for
approximate location of development zone). Detailed information about the wetland
vegetation, hydrology and soil characteristics of each wetland are addressed below.
Vegetation
Wetland A and B have a similar vegetation theme, containing an overstory of red alder
(Alnus rubra, FAC) and western red cedar (Thuja plicata, FAC), with an understory of
dominated by salmonberry (Rubus spectabilis, FAC+), slough sedge (Carex obnupta,
OBL), water parsely (Oenanthe sarmentosa, OBL), piggyback plant (Tolmiea menziesii,
FAC), skunk cabbage (Lysichiton americanum, OBL) wild lilly of the valley
(Maianthemum dilatatum, FAC) and creeping buttercup (Ranunculus repens, FACW).
Wetland B also contains deer fern (Pteridium aquilinum, FAC), while portions of
Wetland A contain reed canarygrass (Phalaris arundinacea, FACW) and soft rush
(Juncus effufus, FACW).
The upland vegetation within the parcel consists of Douglas fir (Pseudotsuga menziesii,
FACU), western hemlock (Tsuga heterophylla, FAC), western red cedar (Thuja plicata,
FAC), salal (Gaultheria shallon, FACU), salmonberry (Rubus spectabilis, FAC),

swordfern (Polystichum munitum, FACU), holly (Ilex aquifolium, NI), Oregon grape
(Mahonia nervosa, UPL) and piggyback plant(Tolmiea menziesii, FAC).
Soils
All test pits excavated within Wetland A area revealed a two-layer profile consistent with
the mapped soil type, Bellingham silty clay loam. The upper layer consists of silt loam of
matrix chroma IOYR 3/1, and the lower layer consist of silty clay loam of matrix chroma
10YR 4/1 with many, medium-sized, distinct mottles of matrix chroma 10YR 4/6. Test
pits excavated within Wetland B revealed two different soil profiles; one test pit
consisting of muck to 12 inches, and the test pit revealed a profile consistent with the
mapped soil type, Bellingham silt loam, similar to the soil profiles in Wetland A.
Wetland hydric soils are indicated by a low-chroma (equaling one) in all wetland test
pits, a sulfidic odor present within the test pit consisting of muck in Wetland A, soil
profiles consistent with the mapped hydric soil Bellingham silty clay loam in both
Wetlands A and B, mottles present within matrix chromas less than 2, and iron
concretions.
The soil profiles observed in known upland test pits were consistent with the mapped soil
type, Alderwood gravelly sandy loam (Ab). Upland test pits also exhibited a two-layer
soil profile. The upper layer consists of gravelly sandy loam approximately eight to ten
inches deep of matrix chroma IOYR 3/3 and 5YR 4/3. The lower profile contained less
gravel with a matrix chroma of IOYR 6/3. No hydric soil indicators were present in
upland soil test pits.
Hydrology
Within Wetland A, hydrology was indicated by FAC-neutral vegetation, drainage
patterns, soils consistent with the mapped hydric soil (Bellingham silt loam, Bd), and
water-stained leaves. In addition, portions of the wetland were inundated up to twelve
inches during the growing season. Within Wetland B, hydrology was indicated by FAC-
neutral vegetation, drainage patterns, water stained leaves, standing water/soil saturation
within the test pits, and soils consistent with the mapped hydric soil (Bellingham silt
loam, Bd). Upland test pits showed no indicators of wetland hydrology.
WETLAND & STREAM EVALUATION
Wetland A meets criteria for a Depressional wetland per Washington State Wetland
Rating System for Western Washington (Hruby 2004) for the purposes of rating. 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 61 points on the
state rating form. The score for water quality functions in this wetland is 18,
hydrological functions scored 20, and the score for habitat functions is 23 (see Appendix
C for rating form). According to Table 17.01.070 E of the Mason County Resource
Ordinance, the base buffer width for a Category 11 Wetlands scoring between 20 and 28
points in habitat function,within parcels intended for Moderate Impact Land Use require
a base buffer width of 110 feet with an additional 15-foot building setback. Moderate

Impact Land Use is described in Table 17.07.070 B of the Mason County Resource
Ordinance as single-family residential lots or residential subdivisions with 1 unit/acre or
less.
Wetland B also meets criteria for a Depressional wetland per Washington State Wetland
Rating System for Western Washington(Hruby 2004) for the purposes of rating. 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 68 points on the
state rating form. The score for water quality functions in this wetland is 24,
hydrological functions scored 20, and the score for habitat functions is 24 (see Appendix
C for rating form). According to Table 17.01.070 E of the Mason County Resource
Ordinance, the base buffer width for a Category II Wetlands scoring between 20 and 28
points in habitat function, within parcels intended for Moderate Impact Land Use require
a base buffer width of 110 feet with an additional 15-foot building setback. Moderate
Impact Land Use is described in Table 17.07.070 B of the Mason County Resource
Ordinance as single-family residential lots or residential subdivisions with I unit/acre or
less.
The channel located west of the property originates from Wetland B. The stream meets
criteria for a fishbearing channel, based on the DNR stream map classification as a type
"F" stream (fishbearing) (See Figure 5. WA DNR Map). In Mason County, fishbearing
streams are identified as type F streams, and require a 150-foot buffer with an additional
15-foot building setback. The wetland buffer encompasses the entire stream buffer
within the parcel.
BUILDABLE AREA IDENTIFIED
The northeastern portion of the property includes approximately 1/4 acre of upland area
outside the above mentioned wetland setbacks. This area appears to be of sufficient size
and of suitable topography to accommodate the proposed single family home and onsite
septic. Buffers surrounding this area have been flagged in the field for the purpose of on-
site planning. The septic test holes appear to be within the 15-foot building setback, but
do not encroach into the 110-foot buffer of Wetland A.
CONCLUSION
This wetland report documents the presence of two Category II Depressional Wetlands
within the western and eastern portions of the subject property. According to Table
17.01.070E of the Mason County Resource Ordinance, the wetlands each require a 110-
foot buffer with an additional 15-foot building setback for Moderate Impact Land Use
(single-family residential lots with less than one unit per acre). A fishbearing channel
meeting criteria for a type F stream drains from Wetland B, and is located within 100 feet
of the western property boundary. Type F streams in Mason County require a buffer of
150-feet with and additional 15 foot building setback.

APPENDIX B
Soil Survey Text
ALDERWOOD SERIES
The Alderwood series consists of brown, well-drained, upland soils. They have
developed from mixed gravelly glacial till dominated by acid igneous rock. The
imbedded gravel is mainly granite and quartzite. Rainfall is 45 to 60 inches a year. The
native vegetation is a dense forest consisting almost entirely of Douglas-fir and a dense
understory of salal, Oregon-grape, vine maple, and huckleberry. Northeast of the Hood
Canal the understory is mainly rhododendron. Alderwood soils occupy the extensive
rolling glacial moraines, and they are the dominant soils in the eastern part of the county.
The Alderwood soils are associated with the somewhat excessively drained Everett and
Indianola soils and with the moderately well drained Kitsap soils. Shelton and Hoodsport
soils differ from the Alderwood soils in that they have developed under high rainfall and
from glacial till having a much higher content of basic igneous rock. The Shelton and
Hoodsport soils are more reddish throughout the profile. The Shelton soils are usually
deeper to the cemented till than the Alderwood soils.
Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab).-This is the most
extensive, soil of the Alderwood series. It occupies undulating to rolling moraines. In
undisturbed areas a 1- to 2-inch mat of very dark brown, acid organic matter is on the
surface. This grades to a thin, dark grayish-brown, highly organic mineral soil. The
surface soil consists of a friable, brown, medium acid gravelly sandy loam 8 to 13 inches
deep. It has a weak granular structure and contains numerous rounded shot. Below the
surface soil, to depths ranging from 18 to 24 inches, is a pale-brown gravelly sandy loam
that is very friable, is single grained; and contains small to moderate amounts of shot .
Between this layer and the cemented till is a 3- to 10-inch layer of very pale brown
gravelly sandy loam. It contains no shot and is firmer but has the same texture as the
layer above. However, it is faintly to distinctly spotted and horizontally streaked with
brown and yellow. The cemented till consists of light-gray, gravelly sandy loam, and it
normally occurs at depths ranging from 24 to 32 inches. It is impermeable to roots and
very slowly permeable to water. The first few inches is usually laminated and streaked
with reddish brown and yellow. Below this, to a depth of many feet, the till is uniformly
cemented, fairly uniform light gray, and medium to strongly acid. A thin mat of roots
often lies over the till. The cemented substratum tends to restrict the rapid downward
movement of moisture. Use and suitability.-Not more than about 5 percent of this soil has
been cleared and is used for crops or pasture. Most of the cultivated acreage is near the
inlets of Puget Sound in the vicinities of Arcadia and Allyn. In this area the Alderwood
soils are associated with the better agricultural soils of the Cloquallum, Sinclair and
Kitsap series. Hay, small grains, pasture, fruits, nuts, grapes, and berries are the principal
crops grown on the Alderwood soils. The lack of subsoil moisture damages crops in
summer. For this reason, early maturing, short-season crops are suited best to this soil.
Yields of all crops are usually fairly low because of low fertility and the dry summers.
Pastures produce good forage in spring and late in fall if proper plants are used and
management is good. The deeper soils are suited best to fruits, nuts, and grapes. The
uncleared and remote areas are better suited to forestry than to cultivated crops. Nearly
all the uncleared acreage is in second-growth forest 70 to 80 years of age. Shallowness to
the compact till often inhibits growth of the older trees. The soil, however, is well suited
to production of Christmas trees. Douglas-fir readily restocks in thick stands containing
trees of good form. Stands of small trees are often thinned and pruned to maintain good
form of growth. The growing of Christmas trees has expanded rapidly in the past few
years and is now one of the important industries in the county. It is one of the proper uses
of the cutover lands that are not in a high site class. Alder-wood soils need barnyard
manure, green manure, nitrogen, or legumes to maintain a fertility for crop production.
Phosphate fertilizers and green manure or barnyard manure greatly improve fertility.
Nitrogen fertilizer is often applied with barnyard manure or when cover crops are plowed
under. The fertilizer furnishes additional nitrogen needed to hasten decay of the organic
matter. This soil is in capability subclass Vls and in site classes 4 and 5 for Douglas-fir.
Small areas along- the border, where the soil is more than 32 inches deep to compact till,
are in site classes 3 and 4 for Douglas-fir.
BELLINGHAM SERIES
The Bellingham series consists of poorly drained, very dark gray silty soils. They occupy
upland depressions and glacial like basins. They have developed from glacial materials
under rainfall ranging from 4 to 60 inches per year. The native vegetation is a dense
forest of alder, maple, willow, cedar, and an occasional spruce and aspen. Under the
forest is spirea and a dense growth of wild rose, sedges, and watertolerant grasses and
shrubs. Bellingham soils are medium acid and high in organic matter. They are associated
with the Kitsap and Cloquallum soils and with other glacial soils of the uplands
Bellingham silty clay loam, 0 to 3 percent slopes (Be).-Most of this soil is on Squaxin
Island and on other islands off Pickering Passage. It is closely associated with
Bellingham silt loam, 0 to 3 percent slopes, but differs from it in having finer textured
surface soil and upper subsoil. The lower subsoil is very dense, and 24 to 34 inches from
the surface it rests on dense clay sediments or drift. This soil is also closely associated
with the Kitsap soils. Use and suitability.-This soil is more difficult to drain than
Bellingham silt loam, 0 to 3 percent slopes, and is more dense if worked under adverse
moisture conditions. Otherwise, it is similar to that soil in use, crops, and yields. This soil
is in capability subclass IVw; it is fair for red alder, Oregon-maple, willow, hemlock,
spruce, and redcedar.

Does the wetland being rated meet any of the criteria below?
If you answer YES to any of the questions below you will need to protect the wetland according to the
regulations regarding the special characteristics found in the wetland.
Check List for Wetlands that Need Special Protection, YES NO
and That are Not Included in the Rating
SP 1. Has the wetland been documented as a habitat for any Federally listed Threatened or
Endangered plant or animal species(TIE species)? X
For the purposes of this rating system, "documented" means the wetland is on the appropriate
state or federal database.
SP2. Has the wetland been documented as habitat for any State listed Threatened or Endangered
plant or animal species? For the purposes of this rating system, "documented" means the X
wetland is on the appropriate state database.
SP3. Does the wetland contain individuals of Priority species listed by the WDFW or the state? X
SP4. Does the wetland have a local significance in addition to its functions? For example, the
wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or X
in a local management plan as having special significance.
To complete the next part of the data sheet you will need to determine the
Hydrogeomorphic Class of the wetland being rated
The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions
needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key
below. See p. 24 for more detailed instructions on classifying wetlands.
Wetland Rating Form—western Washington(11/04) Page 1 of 8
Classification of Vegetated Wetlands for Western Washington
Wetland Name: Lizotte Wetland A Date: 3/13/08
1. Are the water levels in the wetland 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 Riverine 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 11 estuarine wetlands have changed (see p. ).
2. Is the topography within the wetland flat and precipitation is only source (>90%) of water to it.
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 wetland meet both of the following criteria?
The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the
surface)where at least 20 acres(8ha) are permanently inundated (ponded or flooded);
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 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 1 foot deep).
NO—go to 5 YES—The wetland class is Slope
5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The
flooding should occur at least once every two years, on the average, to answer"yes". The wetland 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 wetland 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 wetland located in a very flat area with no obvious depressional and no stream or river running through it and
providing water. The wetland 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 seems to be difficult to classify. 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. Sometimes we find
characteristics of several different hydrogeomorphic classes within one wetland boundary. 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 being rated. If the area of the second class is less than 10% classify the wetland using the first class.
Slope+ Riverine Riverine
Slope+Depressional Depressional
Slope+Lake-fringe Lake-frin e
Depressional +Riverine along stream within boundary Depressional
Depressional +Lake-fringe Depressional
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.

and/or forbs form the natural climax plant community.
Talus: Homogenous areas of rock rubble ranging in average size 0.15—2.Om(0.5—6.5 ft),
composed of basalt, andesite,and/or sedimentary rock,including riprap slides and mine tailings. May
be associated with cliffs.
Caves: A naturally occurring cavity,recess,void,or system of interconnected passages.
Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy 1
coverage of the oak component of the stand is 25%.
Urban Natural Open Space: A priority species resides within or is adjacent to the open space and
uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting
other priority habitats,especially those that would otherwise be isolated; and/or the open space is an

that cover more than 10%of the wetland,then the wetland should be given a dual rating(I/II). Cat. 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
determining the size threshold of 1 acre. Dual

C3 Bogs (seep. 88)
Does the wetland(or part of the wetland) 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 wetland 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 wetland 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 hold 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 wetland 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

SC4 Forested Wetlands (seep. 96)
Does the wetland have at least 1 acre of forest that meet one of these criteria for the Department of Fish
and Wildlife's forests as priority habitats?. If you answer yes you will still need to rate the wetland
based on its function.
Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a
multi-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
100%; decay, decadence, numbers of snags, and quantity of large downed material is generally

Hydrogeomorphic Class of the wetland beingrated.
The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions
needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key
below. See p. 24 for more detailed instructions on classifying wetlands.

Classification of Vegetated Wetlands for Western Washington
Wetland Name: Lizotte Wetland B Date: 3/13/08
1. Are the water levels in the wetland 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 Riverine 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 II estuarine wetlands have changed (see p. ).
2. Is the topography within the wetland flat and precipitation is only source(>90%) of water to it.
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 wetland meet both of the following criteria?
The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the
surface)where at least 20 acres (8ha) are permanently inundated (ponded or flooded),-
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 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 .1 foot deep).
NO—go to 5 YES—The wetland class is Slope
5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The
flooding should occur at least once every two years, on the average, to answer"yes". The wetland 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 wetland 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 wetland located in a very flat area with no obvious depressional and no stream or river running through it and
providing water. The wetland 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 seems to be difficult to classify. 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. Sometimes we find
characteristics of several different hydrogeomorphic classes within one wetland boundary. 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 being rated. If the area of the second class is less than 10% classify the wetland using the first class.

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.

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.
Prairies: Relatively undisturbed areas (as indicated by dominance of native plants)where greases
and/or forbs form the natural climax plant community.
Talus: Homogenous areas of rock rubble ranging in average size 0.15—2.Om(0.5—6.5 ft),
composed of basalt, andesite,and/or sedimentary rock, including riprap slides and mine tailings. May
be associated with cliffs.
_ Caves: A naturally occurring cavity,recess,void,or system of interconnected passages.
Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy 3
coverage of the oak component of the stand is 25%.
Urban Natural Open Space: A priority species resides within or is adjacent to the open space and
uses it for breeding and/or regular feeding;and/or the open space functions as a corridor connecting
other priority habitats,especially those that would otherwise be isolated; and/or the open space is an
isolated remnant of natural habitat larger than 4 ha(10 acres)and is surrounded by urban
development.
Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands,usually semi-enclosed
by land but with open,partly obstructed or sporadic access to the open ocean, and in which ocean
water is at least occasionally diluted by freshwater runoff from the land. The salinity may be
periodically increased above that of the open ocean by evaporation. Along some low-energy
coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward
to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow.
Includes both estuaries and lagoons.
_ Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches,and
may also include the backshore and adjacent components of the terrestrial landscape(e.g.,cliffs,
snags,mature trees,dunes,meadows)that are important to shoreline associated fish and wildlife and
that contribute to shoreline function(e.g.,sand/rock/log recruitment,nutrient contribution,erosion
control).

CATEGORIZATION BASED ON SPECIAL CHARACTERISTICS
Please determine if the wetland meets the attributes described below
and circle the appropriate answers and Category.
Wetland Type—Check off any criteria that apply to the wetland. Circle the Category when the appropriate
criteria are met.
SC1 Estuarine wetlands? (see p.87)
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 X
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? Cat. 1
YES =Category I NO=go to SC 1.2
SC 1.2 Is the wetland at least 1 acre in size and meets at least two of the following conditions?
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 sp are only species
that cover more than 10%of the wetland,then the wetland should be given a dual rating(1/11). Cat.II
The area of Spartina would be rated a Category H while the relatively undisturbed upper marsh
with native species would be a Category 1. Do not, however, exclude the area of Spartina in
determining the size threshold of 1 acre. Dual
At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed Rating or un-mowed grassland n g
The wetland has at least 2 of the following features: tidal channels, depressions with open water, I/II
or contiguous freshwater wetlands.
C2 Natural Heritage Wetlands (seep. 88)
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 KWHP/DNR.)
S/T/R information from Appendix D or accessed from WNHP/DNR web site
YES Contact WNHP/DNR(see p. 88)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
or endangered plant species? Cat I
YES =Category 1 NO X
C3 Bogs (seep. 88)
Does the wetland(or part of the wetland) 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 wetland 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 wetland 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 hold 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 wetland 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
YES=Category I NO=Is not a bog for purpose of rating
