WETLAND DELINEATION AND ANALYSIS REPORT &
RESTORATION PLAN
Shearer Property
Haven Lake
Mason County,Washington
INTRODUCTION
The Wetland Corps has been authorized by Kevin Shearer to perform wetland delineation at the
property located off of NE Haven Lake Drive in Mason County County, Washington, (Tax
Identification Numbers 223304290001, 223304290002, 223304290003, and 223304290004). The
delineation was performed to identify regulated wetlands and associated buffers within a cleared
portion of the ownership, which occupies mainly the northeastern quarter of the entire property. In
addition to the wetland delineation, a restoration plan is outlined to address completed removal of
vegetation within portions of one wetland and wetland buffers.
The subject property is located in the SE 1/4 of Section 30, Township 23 North, Range 02 West
(Figure 1 Vicinity Map). The four parcels total 20.55 acres, and are accessed via NE Haven Lake
Drive.
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 study area is confined to the central and northeastern portion of the parcel, and consists of a
recently cleared and graded area, adjacent to a second growth forested/shrub community of Douglas
fir and western white pine with an understory of salal, evergreen huckleberry and bracken fern.
Five speculated wetland areas are located within the study area, and consist of either open water
within cleared areas or shrub/herbaceous vegetation comprised of dense patches of spirea, with
lesser amounts of slough sedge and soft rush. Topography on the site is generally flat, with a low
gradient slope from the north to the southern portion of the ownership. Existing development
surrounding the subject property is comprised of Washington State forest land and single-family
residences.

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, the
1974 United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) maps,
and the Soil Survey of Mason County Area, Washington (USDA, 1951), and Mason County's
critical areas regulations—Mason County Resource Ordinance 17.01.070 Wetlands.
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.
Since segments of wetland boundaries are vague and/or difficult to identify due to recent land
alteration, the extent and location of project site wetlands were determined during field work
performed throughout several site visits between August of 2006 and February 2007. In order to
assess the presence of wetland hydrology indication in both the growing and nongrowing season,
field work was conducted duringdrought events in August and flooding events in November and
� � g
December. Observing the speculated wetlands during different times of year improved accuracy in
determining the type and extent of wetlands presumed to exist on site before the clearing activities.
Specific field methodology used in determining the extent and location of wetland areas include:
1 As part of the initial project site reconnaissance, the study 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 collected at seven 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.
Wetland Evaluation
Wetlands were classified and razed using the categories set forth in the Mason County Resource
Ordinance 17.01.070, which defines wetland categories according to Washington State Wetland

Rating System, Western Washington, 2"d Edition, or as amended hereafter(Department of Ecology
1993). This wetland evaluation used the new rating manual, Washington State Wetland Rating
System for Western Washington (Hruby 2004). This system identifies various complexities within
wetland structures, habitat attributes and various functions associated with wetlands. The rating
form completed for this wetland is provided in Appendix C.
BACKGROUND INFORMATION
Mason County Soil Survey
The soil survey of Mason County indicates one onsite soil type(USDA, 1951):
The soil type mapped within the parcel has been identified as: Ab-Alderwood gravelly sandy
loam. 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.
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 US Fish and Wildlife Service,National Wetlands Inventory(online wetlands mapper) shows no
identified wetland areas within the vicinity of the ownership. The NWI map is shown in Figure 3.
Department of Natural Resources
The Washington State Department of Natural Resources Water Resource Map shows no streams
within the project vicinity. The nearest stream is mapped approximately 700 feet east of the
property. The DNR Water Resource Map is shown in Figure 5.
Mason County GIS
Aerial photos taken in 2005 posted on the Mason County GIS website were used to approximate
previous vegetative conditions prior to recent clearing.

Five speculated wetlands were identified within the study area. After further observation, three of
the five wetlands meet Department of Ecology criteria for regulated wetlands indicating
hydrophytic vegetation, wetland hydric soils and wetland hydrology. The wetlands are delineated
in the field with pink flagging, and are identified in this report as Wetland A, Wetland B, and
Wetland C. The wetlands are generally located within the central and northeastern portion of the
ownership. Wetland A is located south of Wetland B, and is north of Wetland C. All three
wetlands are characterized by dense communities of spirea. The vegetated portions of the buffers of
Wetlands A and C, not included in the cleared area, are comprised of a second growth community
of Douglas fir and western white pine.
Wetland B is in a depressional area located northeast of Wetland A and north of Wetland C.
Portions of the vegetation within Wetland B have been removed, as well as the entire associated
buffer. The area was observed for wetland indicators due to the drastic difference in soil
characteristics compared to surrounding upland areas, and the presence of facultative wetland and
obligate wetland vegetation comprised of spirea (Spiraea douglasii, FACW) and slough sedge
(Carex obnupta, OBL) subsisting within both the in tact portions of the wetland, and beginning to
volunteer within the recently cleared portions of the wetland.
Two speculated wetland areas nearly devoid of vegetation were observed within the study site. The
wetlands were observed for wetland parameters based on the presence of inundation up to 12 inches
in depressional areas during the nongrowing season. One speculated wetland area is located
adjacent to Wetland B in a depressional area, and one speculated wetland is located north of
Wetland A and west of Wetland B. The northern speculated wetland contains hydrophytic
vegetation, wetland hydric soils, and wetland hydrology indicators within an area less than 100
square feet in size. Due to lack of hydrophytic vegetation and wetland hydric soil indicators within
the majority of the depressional area,this area does not meet criteria for a regulated wetland.
The speculated wetland to the south is entirely devoid of vegetation, and lacks wetland hydric soil
and wetland hydrology indicators, and therefore does not meet criteria for a regulated wetland. It
appears that the speculated wetland areas have recently developed after the vegetation removal, and
now function as seasonal wetlands that are inundated and/or saturated during the non-growing
season, but not for a portion of the growing season that would meet DOE wetland criteria (5%-
12%).

Data was collected at seven sample plot locations. Sample Plots Al and A2 are located near the
western and northern portions of Wetland A. Sample Plots B3 and B4 are located within the
northern and southern portions of Wetland B. Sample Plot C5 is located in the northern portion of
Wetland C. Sample Plots D6 and D7 are located in the two speculated wetland areas that failed to
indicate all three wetland parameters. Specific findings on wetland soils, hydrology, and vegetation
for sample plots are provided below.
Soils
Wetland test pit data within Wetlands A and B only include soil characteristics beyond 5 inches,
given that most wetland test pits revealed an upper layer of non-native soil that was pushed into the
wetland boundary during clearing activity. However, wetland hydric soil is indicated in wetland
test pits Al, A2, B3, B4, and C5 by a mucky soil with a low-chroma matrix equaling one to 12
inches deep. Wetland test pits D6 and D7 revealed soil characteristics consistent with the profiles
exhibited throughout upland test pits, consisting of gravelly sandy loam to 20 inches with matrix
chromas varying from 1 OYR 3/2 to 1 OYR 4/6 and 6/4.
Upland test pits revealed similar characteristics throughout the soil profile consistent with
Alderwood gravelly sandy loam. No wetland hydric soil indicators were present in upland test pits.

Hydrology
The wetland hydrology indicators for Wetlands A, B and C include drainage patterns, drift lines,
FAC-neutral vegetation, water-marks on trees and water-stained leaves. During our initial
inspections in August, neither saturation to the surface or inundation were present. Into the wet
season, inundation up to 1 foot in some areas, soil saturation and standing water in the test pits were
observed in wetlands and speculated wetlands. Upland test pits showed no indicators of wetland
hydrology.
Vegetation
Wetlands A and C have similar vegetative communities, dominated by a dense shrub layer that
extends nearly to the wetland boundary, whereas shrub species within Wetland B are scattered due
to the recent vegetative alteration within the wetland boundary. Volunteer vegetation returning
within Wetland B is comprised of slough sedge (Carex obnupta, OBL) and soft rush (Juncus
effufus, FACW), and was used during the delineation as the most accurate indication of the extent of
the boundary of Wetland B, given the recent circumstances.
Overall, the vegetation in the wetlands is distinct from the surrounding upland areas most notably
because of the presence of obligate and facultative wetland species in the herb and shrub layers
including spirea (Spiraea douglasii, FACW), slough sedge (Carex obnupta, OBL), and soft rush
(Juncus effufus, FACW). Vegetation within one speculated wetland area consists of a small patch
(less than 100 square feet)of slough sedge(Carex obnupta, OBL).
The speculated wetland area south of Wetland B contains no vegetation due to the removal of
vegetation and regrading in the summer of 2006. Since one of the parameters of the speculated
wetland have been completely removed, this area meets criteria for an Atypical Situation. When
determining vegetation in atypical situations, such as the removal of vegetation, all possible
evidence regarding the type of plant community prior to alteration should be used in determining
hydrophytic vegetation, according to Section F. Subsection 1. of the Field Guide for the 1987 Corps
of Engineer Manual. Based on aerial photos from the Mason County GIS that were taken in 2005,
and a general walk through of the entire property completed by Lee Boad in 2004 for a separate
project, the speculated wetland areas previously contained vegetation consistent with that in known
upland areas including western white pine (Pinus monticola, FACU-), Douglas fir (Pseudtosuga
menziesii, FACU), salal (Gaultheria shallon, FACU) and evergreen huckleberry (Vaccinium
ovatum, FACU). Based on these vegetative data sources, we have determined that hydrophytic
vegetation was not present within the majority of the speculated wetland area south of Wetland B
prior to vegetation removal.
The vegetation within the speculated wetland area north of Wetland A and east of Wetland B
contains a small patch (less than 100 square feet) of slough sedge (Carex obnupta, OBL). Given the
non-hydrophytic vegetative community prior to vegetation removal and the small size of the
representative vegetation community during the latest site visit in February 2007, we have
determined that hydrophytic vegetation was not present within the majority of the speculated
wetland area north and Wetland A prior to vegetation removal.

Upland plant species include Douglas Fir (Psuedotsuga menziesii, FACU), western white pine
(Pinus monticola, FACU-), salal (Gaultheria shallon, FACU), evergreen huckleberry (Vaccinium

blackberry(Rubus discolor, FACU).
WETLAND EVALUATION
Wetland Categorization
Because the clearing activity was completed independent of county review or permitting, wetlands
A, B, and C were rated based on functions and values existing prior to wetland and/or or buffer
alteration. Each regulated wetland is classified as a depressional wetland per Washington State
Wetland Rating System for Western Washington (Hruby 2004). Each wetland is in a topographical
depression with either no surface water outlet or a slightly constricted surface water outlet.
Based on functional attributes associated with the wetland, Wetland A meets criteria for a Category
III wetland, scoring 37 points on the state rating form, with 19 points in habitat functions.
According to Table 17.01.070 D of the Mason County Resource Ordinance, Category III Wetlands
scoring less than 20 points in habitat function, within parcels intended for Moderate Impact Land
Use require a base buffer width of 60 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.
Wetland B meets criteria for a Category III wetland, scoring 37 points on the state rating form, with
19 points in habitat functions. According to Table 17.01.070 D of the Mason County Resource
Ordinance, Category III Wetlands scoring less than 30 points in habitat function, within parcels
intended for Moderate Impact Land Use, require a base buffer width of 60 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.
Based on functional attributes associated with the wetland, Wetland C meets criteria for a Category
III wetland, scoring 40 points on the state rating form, with 18 points in habitat functions.
According to Table 17.01.070 D of the Mason County Resource Ordinance, Category III Wetlands
scoring less than 20 points in habitat function, within parcels intended for Moderate Impact Land
Use require a base buffer width of 60 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.
RESTORATION PLAN
Buffer Restoration
It is recommended that all cleared areas within the wetland buffers are restored using native
vegetation planting. The restoration of a moderately dense forested/shrub community within the

cleared portions of the wetland buffers are expected to improve values and function of the wetlands
within the study site. The total area to be restored occupies 69,000 square feet. It is recommended
that plants be installed as described in the Native Plantings section below.
Native Plantings
It is recommended that potted plants be used as opposed to bare root seedlings. The following
plant species and potted sizes are recommended:
Trees: western white pine (Pinus moniticola,FACU-)-2 gallon
Douglas fir(Pseudotsuga menziesii) - 2 gallon
Shrubs: Oregon grape (Mahonia nervosa)- 1 gallon
salal (Gaultheria shallon)— 1 gallon
evergreen huckleberry (Faccinium ovatum) - gallon
nootka rose(Rosa nutkana)— I gallon
beaked hazelnut(Corylus cornuta)— 1 gallon
Indian plum(Oemleria cerasiformis)— 1 gallon
oceanspray (Holodiscus discolor)— I gallon
Pacific ninebark(Physocarpus capitatus)— 1 gallon
California black currant (Ribes bracteosum)— 1 gallon
western thimbleberry(Rubus parviflorus)— 1 gallon
red elderberry(Sambucus racemosa)— I gallon
Native Planting Guidelines
It is recommended that plantings be installed within the identified mitigation zone to achieve the
following densities. A minimum of I tree species and five shrub species from the above list are
recommended.
trees- 10' on center
shrubs- 5' on center
These densities will provide a moderately dense, structurally diverse plant community within the
mitigation zone. To fulfill the above mentioned planting density recommendation, the buffer of
Wetland A will be planted with a total of 240 trees and 720 shrubs, Wetland B will be planted with
a total of 420 trees and 1260 shrubs, and Wetland C will be planted with 30 trees and 90 shrubs. A
total of 690 trees and 2070 shrubs will be planted within all portions of the buffers that have been
removed of vegetation; a total area of 69,000 square feet. It is recommended that installation be
done as single trees and or clusters of three shrubs,on approximate 10-foot centers.
Typically, planting should occur during winter dormancy. The optimum time for planting is during
February and March, however, the need to complete the project in a timely manner may call for
planting to occur outside optimum time periods. No machinery earthwork will be necessary to
implement this restoration plan; planting holes for specified vegetation installation can be done by
hand. No additional clearing or grading should be necessary for site restoration. All installed

vegetation shall be marked with colored flagging to facilitate monitoring inspections. The
monitoring program is recommended to insure project effectiveness.
Invasive species such as Himalayan blackberry, reed canary grass, Japanese knotweed, and English
Ivy may invade the restoration zones. These species are stubborn competitors for light and nutrients
and limit success of native plants. Invasive species should be removed from the restoration zone
should they invade. Herbicides should not be used to achieve this due to the proximity to the
wetlands. Persistent cutting during the growing season is sufficient to offset the rhizomes of
invasive species if they become a problem.
Wetland Restoration
Wetland B has been modified by partial filling, grading, and vegetation removal. Upland material
has been pushed into the wetland along portions of the wetland edge. Hydric soil within the
wetland has been pushed around resulting in gradual elevated areas within the wetland. Scrub shrub
vegetation has been removed from approximately 60 percent of the wetland.
Fill Removal
The wetland edge as staked in the field represents the outermost extent of the wetland area. All
upland soil existing waterward of the stakes should be removed from the wetland and spread
throughout the adjacent upland. Wetland Corps staff should be on-site during this work.
Restoration of Wetland Contours
The wetland contours should be re-established to a single depression with the lowest point centrally
located within the wetland and a moderate slope toward upland areas. Upland/wetland transition
areas should consist of a slope of 10-15 percent toward the lowest point of the wetland. This can be
completed during the driest portion of the year (July-August) when no inundation or surface
saturation is present. Small rubber tracked equipment should be used for this work. Steel tracked
equipment should not be used. Wetland Corps staff should be on-site during this work.
Vegetation Restoration
The wetland area currently contains native wetland soil and a remaining patch of vegetation. The
removal of fill, restoration of wetland contours, and presence of a nearby seed source will provide
an optimum environment for natural vegetation recruitment. This being the case supplemental
planting within the wetland is not recommended. Monitoring the site for invasive species such as
Himalayan blackberry, reed canary grass, Japanese knotweed, or English Ivy will be necessary to
insure plant recruitment is exclusively native plants. Any invasive species observed should be
removed immediately.
Best Management Practices
Recommended Best Management Practices for this project are as follows:
• Perform all wetland restoration work during July or August.
• Install silt fencing around wetland areas to prevent siltation of waters.
• Minimize amount of erodible soils at any given time to the maximum extent feasible.

• Check all equipment dail for leaks. Refueling and lubrication of equipment should occur
Y g �I P
off site. Do not store any fuel, lubricants, chemicals, or hazardous substances outside
overnight within the project area.
• No construction debris or supplies should be placed in existing wetland buffer areas or
anywhere within the wetland boundaries.
• Do not apply any chemicals when there is a possibility of rain.
• Comply with all permits and requirements of governing authority.
MONITORING
Monitoring of the site will begin the first fall following restoration and maintained on a seasonal
basis. The information gathered will provide the following: 1) condition of reintroduced plant
species; 2) the use of the site by wildlife species; 3) conditions of wetland hydrology; 4) any
occurrence of exotic species within the restoration or wetland zone; 5)vegetation recruitment within
wetland B; 6) any corrective measures that may be deemed necessary to provide desired conditions.
Two photo points will be established that portray representative restoration areas from each side of
the property. One photo will be provided that portrays wetland B. This monitoring will be in effect
for the duration of five years or longer if required by Mason County. The information gathered will
be provided in an annual report and submitted to the Director of Mason County Department of
Community Development.
SUMMARY
This wetland report documents the presence of three depressional wetlands identified in this report
as Wetlands A, B and C; within the recently cleared portion the property owned by Kevin Shearer
located off of NE Haven Lake Drive. All three wetlands meet Mason County's wetland
classification criteria for Category III Wetlands scoring less than 20 points in habitat function on the
state rating form. According to Table 17.01.070 D of the Mason County Resource Ordinance, the
standard buffer widths for Category III Wetlands in parcels intended for Moderate Impact
Development(Single-family residential lots)is 60 feet with an additional 15-foot building setback.
In addition to the wetland delineation, a restoration plan is outlined to address unnecessary removal
of vegetation within portions of Wetland B and wetland buffers during the recent clearing activities.
The area to be restored with native trees and shrubs occupies an area of 69,000 square feet.

Soil Onsite Conditions based on Mason County Soil Survey
Subject Site Soil:
Soil type one has been identified as: Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab). 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.
A more detailed soil description can be found in Appendix B Mason Soil Survey Text.

2. Effect on Vegetation: No vegetation present within the depression that is a speculated wetland area.
3. Previous Vegetation (Attach documentation): A site visit in July 2004 for a separate project was
completed in the southern portion of the subject property. During that site visit The Wetland Corps, then
identified as Lee Boad Habitat Management and Wetland Services, conducted a general walk through of the
entire property. The vegetation within the approximate location of the speculated wetland area was
comprised of a 2nd growth forested community of western white pine (Pious monticola, FACU-), douglas fir
(Pseudotsuga menziesii, FACU), salal (Gaultheria shallop, FACU), and evergreen huckleberry (Vaccinium
ovatum, FACU); similar to surrounding upland portions of the property that have been left in tact. Based on

Appendix B: Soil Text
I
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 VIs
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.

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.
Slope+Riverine Riverine
Slope+Depressional Depressional
Slope+Lake-fringe Lake-fringe
Depressional+Riverine along stream within bound Depressional
Depressional+Lake-fringe De ressional
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.

multi-layered canopy with occasional small openings,with at least 20 trees/ha(8 trees/acre)>81cm
(32 in)dbh or>200 years of age.
X Mature forests: Stands with average diameters exceeding 53cm(21 in)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.
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—2.0m(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
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

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

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.

C4 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

SP4. Does the wetland have a local significance in addition to its functions? For example,the X
wetland has been identified in the Shoreline Master Program,the Critical Areas Ordinance, or
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 beingrated.
ated.
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: Wetland B Date: 2/21/07
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.
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 Icharacteristics
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.

Hydrogeomorphic Class of the wetland beingrated.
ated.
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: Wetland C Date: 2/21/07
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-Merge(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 I 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
.T .
depressions that are filled with water when the river is not flooding.
P .n g
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 De ressional
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.

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.
