WETLAND DELINEATION AND ANALYSIS REPORT
Michael Jameson & Jean French
Chimacum, Washington
INTRODUCTION
ALKAI Consultants, LCC, (ALKAI) has been authorized by Michael Jameson and Jean
French to perform a wetland delineation at the property located on West Uncas Road in
Discovery Bay, Jefferson County, Washington (Tax Identification Number 902264043),
The delineation was performed on April 19, 2007. The proposed project involves
removing the current mobile home residence, decommissioning the existing septic
system, and constructing a new single family residence and septic system. Because the
best drained soils are close to the wetland edge, a delineation was required to determine
the best location for the septic system,
For the purposes of Federal, Washington State, and Jefferson County jurisdictional
oversight, methodology used for the wetland delineation is consistent with the definition
provided in paragraph 25a of the Washington State Wetlands Identification and
Delineation Manual (Washington State Department of Ecology [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 property is located in the southeast quarter of Section 26, Township 29
North, Range 02 West (Figure 1). The parcel is a 3-acre lot, roughly rectangular in
shape, located at 1450 West Uncas Road in Discovery Bay, Washington, The parcel is
primarily comprised of lawn and pasture plant communities dominated by black
cottonwood, grasses and rushes, A wooded upland along West Uncas Road is dominated
by big-leaf maple, red alder and Sitka spruce with an understory of osoberry, vine maple,
red elderberry and sword fern, Approximately one third of the parcel is forested,
The site contains a single family residence, outbuildings and horse pasture, The parcel is
located in the Snow Creek valley with gentle east-facing slopes, except near West Uncas
Road where approximately 15 percent slopes run north to the pasture, A wetland is
located on the parcel, referred to here as Wetland A. The wetland is associated with an
unnamed tributary to Snow Creek, and is located at the eastern edge of the property.
Figure 2 illustrates the approximate wetland boundaries,

METHODOLOGY
Review of Existing Information
Consistent with procedures detailed in the Washington State Wetlands Identification and
Delineation Manual (1997 Manual) (Ecology 1997), ALKAI gathered preliminary
information on the project site prior to the field review and delineation. General
information sources included: United States Geological Survey (USGS) topographic
maps, United States Fish and Wildlife Service (USFWS) National Wetland Inventory
(NWI) maps, Soil Survey of Jefferson County Area, Washington (United States
Department of Agriculture [USDA] 1977), Washington State Department of Natural
Resources (DNR) Resource maps, Jefferson County Critical Areas maps and Jefferson
County's Critical Areas regulations - Title 18 of the Jefferson County Code (lCC),
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 project related wetlands were determined during fieldwork
performed on April 19, 2007. Fieldwork was conducted under sunny skies with an
ambient temperature of approximately 53 degrees Fahrenheit. The time of year and
recent precipitation history were considered in assessing the type and extent of wetlands
and stream typing presumed to exist on and in proximity to the site, Wetlands identified
during fieldwork are considered potential wetlands until their presence is confirmed
through Jefferson County or U,S, Army Corps of Engineers review,
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,
Specific field methodologies for plot sampling; hydrology, soil, and vegetation
evaluation; and boundary delineation are described in Appendix A. Data collected at
each sample plot were entered onto a Routine Wetland Determination Data Form
(Ecology 1997), Copies of data forms for each sample plot are provided in Appendix B.

WETLAND EVALUATION
The subject wetland was characterized using the wetland classes defined by the Cowardin
system (Cowardin et al. 1979), The Cowardin system describes wetlands by the plant
communities, soils and hydrologic regimes present. The naming convention was
developed by the USFWS for the NWI maps, Wetlands were also classified and rated
using the categories set forth in JCC 18.15,325, which defines wetland categories
according to Washington State Wetland Rating System, Western Washington, 2nd Edition,
(Ecology 1993). The rating forms completed for this wetland are provided in Appendix
C.
BACKGROUND INFORMATION
Watershed
This parcel is located approximately one-tenth of a mile west of Snow Creek at river mile
1.5. The Jefferson County Sensitive Areas map shows an unnamed Type 3 stream
flowing past the northwest comer of the property, which joins Salmon Creek within one
mile, A Type 5 stream is shown just to the northeast of the property on the Jefferson
County Critical Areas map (Figure 3), During field work, the Type 3 stream was found
running in a ditch along the western property boundary. The portion of the Type 5
stream near the French property is a shallow, ponded depression without a channel.
Jefferson County Soil Survey
The soil survey of Jefferson County indicates two onsite soil types:
. AmD Alderwood gravelly loam, 15 to 20 percent slopes
. Bh Belfast silt loam, heavy variant
The southern portion is mapped as Alderwood gravelly loam. The Alderwood series
consists of moderately well drained soils that have a very slowly permeable cemented
layer at a depth of 20 to 40 inches, The northern portion of the subject parcel is mapped
as Belfast silt loam heavy variant which is listed as a moderately well-drained soil with
inclusions of Belfast silt loam, wet variant, which has poor drainage, Belfast silt loam is
listed as a partially hydric soilin Jefferson County. A more detailed description ofthese
soils is presented in Appendix D. Soil location is illustrated in Figure 4 - Jefferson Soil
Survey map.
National Wetlands Inventory
The wetland delineated by ALKAI on this site is shown on the USFWS NWI map as a
14,9-acre PalustrinelEmergentlSeasonally Flooded (PEMC) wetland (Figure 5), Several
other freshwater wetlands are listed on NWI maps within one-half mile of the project
area, A O,5-acre pond is shown to the west along West Uncas Road, To the northwest, a
10,7-acre emergent wetland is shown. A O,5-acre emergent wetland is shown to the
northeast. To the southeast, a 1,2-acre shrub-scrub wetland and a 2.3-acre emergent
wetland are indicated.

Priority Species Listing and National Heritage Features
The Washington Department of Fish and Wildlife - Habitats and Species map for
Jefferson County indicates that no priority species or national heritage features exist
onsite, No other State Candidate Species, Threatened, Priority or Other Priority Habitats
are located within one-half mile of the subject parcel. The National Heritage Features
Associated with Wetlands data does not list this section of land for rare plant species,
WETLAND DELINEATION RESULTS
General Wetland Conditions
ALKAI delineated the western boundary of a wetland referred to here as Wetland A. The
wetland extends off of the subject parcel to the north and east. The proposed septic
system location is the far southeastern portion of the property near West Uncas Road,
Existing fences define the northern and eastern property boundaries of the parcel. The
wetland is comprised of an emergent plant community that has been grazed, Dominant
plant species include common rush, skunk-cabbage and creeping buttercup. In total, the
wetland covers less than one-quarter of the parcel. A 200-foot transect was located
running from the eastern property boundary southwest towards the proposed septic site,
Data was collected at five points along this transect approximately 50 feet apart, The
data points are referred to as DP 1, DP 2, etc. Completed data forms are included in
Appendix B,
The adjacent parcel to the north was delineated in February 2007 by Olympic Wetland
Resources, Wetland boundaries to the east of the subject property were partially visible
from the French property and from aerial photos, but the exact location of the boundary is
not known,
Soils
Indicators of hydric conditions were found in soil pits at data points DP 1 through DP 4,
Soil textures ranged from silt loam to silty clay, Texture and color were similar to the
description of Belfast Silt Loam in the Soil Survey of Jefferson County Area (USDA
1977), Matrix chroma Munsell readings of two or less with prominent mottles, and the
listing of Belfast silt loam as a partially hydric soil were positive indicators in all four
pits, however the extent of mottling decreased with distance from the wetland,
DP 5 exhibited characteristics similar to the description of Alderwood gravelly loam in
the soil survey, Munsell readings were higher, no mottling was observed and soil
textures were loam and gravelly loam, No hydric indicators were found at DP 5, In a
nearby soil test pit dug by the septic designer Nathan Cleaver, soil texture changed to a
mottled clay loam at approximately 48 inches below surface,
Hydrology
Free water was present in soil pits at DP 1 four inches below the surface at and DP 2
twelve inches below the surface, In addition, the low elevation ofDP 1 and DP 2 and the
slow permeability of the soil was such that occasional inundation was likely, Innundation

was present slightly downslope of DP 1 at the time of field work, DP 1 had slight
sediment deposits from earlier ponding, The strongly hydrophytic vegetation at DP 1
gave a FAC-Neutral test of 3:0, which was another positive indicator of hydrology, Soil
survey mapping ofthe soil as partially hydric was the final indicator of hydrology,
Positive indicators of wetland hydrology could not be found at data points DP 3 through
DP 5. No water was found in pits, except near DP 5 where there was water at 48 inches
in a test hole dug by Cleaver, There were slight elevation differences between DP 2 and
DP 3, which were probably sufficient to result in better drainage at DP 3. Slope
increased significantly between DP 4 and DP 5,
Vegetation
Heavy grazing on the French property and recent grazing on adjacent property to the
north and east made identification of plant species difficult. Nevertheless, 18 species
were identified along the transect, nine of these within the wetland,
The wetland area surrounding DP 1 had vegetation consisting of black cottonwood,
creeping buttercup, common rush, skunk-cabbage, and timothy. Greater than 50 percent
of the dominant species were identified as facultative (F AC) or wetter and therefore met
the wetland criteria for hydrophytic vegetation (Appendix B). In addition, the vegetation
at DP 1 had a F AC-neutral ratio of 3 :0, indicating strongly hydrophytic vegetation,
The percent of dominant vegetation that was hydrophytic declined steadily along the
transect. At DP 2 it was 67 percent, indicating hydrophytic vegetation. At DP 3 and DP
4 only 40 percent of dominant vegetation was hydrophytic, DP 5 had one facultative
species, Sitka spruce, present at the forest edge,
The upland vegetation was distinct from the wetland vegetation, The upland area
surrounding the test pit DP 5 had vegetation that included big-leaf maple, Sitka spruce,
osoberry, vine maple, red elderberry, sword fern and Pacific waterleaf, Less than 50
percent of the dominant species in this area were identified as facultative (F AC) or
wetter, and therefore did not meet the criteria for hydrophytic vegetation.

WETLAND EV ALUA TION RESULTS
Wetland Categorization
Wetland A was rated using the 1993 Wetland Rating System for Western Washington,
The wetland is larger than the subject parcel and the estimated size of the wetland unit is
170 acres, based on verbal communication with Donna Frostholm, Jefferson County
Wetland Specialist. Based on findings of significant habitat value, it scored 22 points on
the state rating system, making it a Category II wetland. Wetland A has been previously
rated on the adjacent Fenter parcel (902264042) by Olympic Wetland Resources in
February, 2007. Olympic Wetland Resources rated it as a Category II wetland, All
Category II wetlands larger than 2,500 square feet are regulated in Jefferson County, The
standard buffer width for a delineated Category II wetland is 100 feet from the wetland
boundary, Informal measurements were taken onsite and the approximate distance
between the proposed septic location and the delineated wetland edge was 160 feet, plus
or minus ten feet.
SUMMARY
This report documents the presence of a depressional wetland on parcel 902264043
located at 1450 West Uncas Road in Discovery Bay, Jefferson County, Washington, The
property is owned by Jean French of Chimacum. Wetland boundaries on the subject
parcel were found to be similar to what is shown on Jefferson County Sensitive Areas
maps, The wetland is a Category II wetland with an associated buffer of 100 feet.
CONFIRMATION
Wetland status depicted in this report has not been confirmed by a government
official, and therefore has no legal status. Agencies with jurisdictional authority
over wetlands at the local, state and federal level need to be consulted for their
signed agreement to our findings before there is any guarantee of no change. Our
estimation for the accuracy of the unconfirmed wetland boundaries portrayed
within this report is ~95%.

Onsite Soil Conditions based on Jefferson County Soil Survey
Alderwood gravelly loam, 15 to 30 percent slopes
(AmD).-This moderately steep soil is.in areas where the rolling upland glacial terraces converge with the steep drainage way
ravines. The surface layer and subsoil are gravelly loam. This soil holds 3 to 6 inches of water available for plants.
Permeability is moderate. Runoff is medium to rapid, and the hazard of erosion is moderate to severe. This soil is used mainly
for tree production and for wildlife habitat and recreation areas. Capability unit VIe-I; woodland group 3d2.
Belfast silt loam, heavy variant (Bh).- This nearly level soil is on flood plains. The upper 26 inches is dominantly dark brown
or dark yellowish-brown, slightly acid to neutral silt loam. Below this, to a depth of more than 60 inches, is mostly dark
grayish-brown or dark-brown, neutral heavy silt loam and silty clay loam mottled with dark red and dark reddish brown.
Included with this soil in mapping are small areas having poor drainage. This soil is moderately well drained. Permeability is
moderately slow. This soil holds about 11 to 13 inches of water available for plants. A seasonal water table is at a depth of2 to
4 feet. Most of the acreage of this . soil is used for permanent pasture, hay, or silage and for many berry, fruit, and vegetable
crops. Capability unit Ilw-l; woodland group 302.
A detailed soil description can be found in Appendix D Jefferson County Soil Survey Text.

Plot Sampline:
A 200- foot transect was located running from the eastern property boundary southwest
towards the proposed septic site. Data was collected at five points along this transect
approximately 50 feet apart. The data points are referred to as DP 1, DP 2, DP 3, DP 4,
and DP 5. The locations of these sample plots are indicated in Figure 2. These sampling
locations were used as sites for the collection of hydrologic, soil, and vegetative data in
accordance with the methodologies set forth in the 1997 Manual. 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
appended to this delineation report.
Hvdroloe:v Evaluation
According to the 1997 Manual, wetland hydrology is present in areas that are inundated
and/or saturated to the surface for a consecutive number of days greater than 12.5 percent
of the growing season (approximately 2 weeks in Western Washington). Saturation to
the surface is assumed when the water table - the level at which standing water is found
in an unlined hole - is found within 12 inches of the surface in a non-sandy soil or within
6 inches of the soil surface in sandy soils.
A small soil test pit was excavated to a depth of 18 to 20 inches at the center of each
sample plot. The extent of soil inundation and saturation as well as the depth to free
water in the test pit were recorded on the Routine Wetland Determination Data Forms as
an indication of potential wetland hydrology. Other recorded potential field indicators of
wetland hydrology, as listed in the 1997 Manual, include oxidized channels
(rhizospheres) associated with living roots, water marks on vegetation or fixed objects,
drift lines, sediment deposition on vegetation and other objects, water-stained leaves,
wetland drainage patterns, and hydric soil characteristics.
Soil Evaluation
The presence of hydric soils was determined consistent with the 1997 Manual.
Fulfillment of the technical criteria for soil can be inferred by using a combination of
published soils information and field indicators. A soil profile to a depth of 16 inches
was extracted from each sample plot test pit and the depth and character of each distinct
soil horizon was recorded. A Munsell soil color chart (Munsell Color, 2000 rev.) was
used to characterize the soil. In accordance with the 1997 Manual field protocol, soil
color, hue, and chroma was recorded for each soil profile immediately below the "A"
horizon or at a depth of 10 inches, whichever is shallower. All information collected on
field soil profiles was recorded on the Routine Wetland Determination Data Form for
each sample plot.

Vee:etation Evaluation
At each sample plot, vegetation was characterized by determining the percent aerial cover
of each plant species occurring' within the herb, shrub, and tree stratum. Dominant
species in each of the three strata ~tree, sapling/shrub, and herb) were identified and
recorded on the Routine Wetland Determination Data Form for each sample plot. The
wetland indicator status of the dominant species' within each vegetation stratum was used
to determine the presence of hydrophytic wetland vegetation. Each species' indicator
status was defined according to Reed (1993). According to the 1997 Manual an area
meets the hydrophytic vegetation criteria when, under normal circumstances, more than
50 percent of the dominant species from each stratum are obligate wetland (OBL),
facultative wetland (F ACW), and/or facultative (F AC) species.
Boundary Delineation
After characteristics of hydrology, soil, and vegetation were compared between the
confirmed upland and wetland sample plots, a boundary determination was made in the
field. The wetland boundary was determined by first noting likely areas of topographic
and vegetative distinction between wetlands and uplands, and then using soil borings to
determine the boundary between hydric and non-hydric soils. The wetland boundary was
marked with flagging spaced at a distance of approximately 20 feet.

Q.1. High Quality Natural Wetland
Circle Answers
Answer this question if you have adequate information or experience to do so. If
not fmd someone with the expertise to answer the questions. Then, if the answer
to questions la, Ib and lc are all NO, contact the Natural Heritage program of
DNR.
la. Human caused disturbances,
Is there significant evidence of human-caused changes to topography or
hydrology of the wetland as indicated by any of the following conditions?
Consider only changes that may have taken place in the last 5 decades. The
impacts of changes done earlier have probably been stabilized and the wetland
ecosystem will be close to reaching some new equilibrium that may represent a
high quality wetland.
la.l Upstream watershed> 12% impervious.
la2. Wetland is ditched and water flow is not obstructed.
la3. Wetland has been graded, filled, logged.
la4. Water in wetland is controlled by dikes, weirs, etc.

Alderwood Series
The Alderwood series consists of moderately well drained soils that have a very slowly permeable
cemented layer at a depth of20 to 40 inches. Slopes range from 0 to 50 percent. Elevation ranges from 100
to 800 feet. These soils formed in glacial till under a forest of mixed coniferous and broadleaved
vegetation. Annual precipitation ranges from 25 to 50 inches. The average annual air temperature is about
49'F. The above 32'F growing season ranges from 160 to 260 days, and the above 280F growing season
ranges from 220 to 320 days. These soils are associated mainly with Beausite, Casey, Clallam, Dick,
Everett, Hoypus, Indianola, Sinclair, and Whidbey soils. In a representative profile a thin layer of organic
litter covers the surface. The top 1 inch of the soil is very dark grayish-brown gravelly fme sandy loam.
Below this, to a depth of 12 inches, is dark yellowish-brown gravelly sandy loam. Beneath this layer, and
continuing to a depth of 30 inches, is gravelly sandy loam that is brown in the upper part and dark grayish
brown and prominently mottled in the lower part. The next layer is a dark grayish-brown cemented layer
that formed in very compact glacial till. Rounded pebbles, cobblestones, and stones are on the surface and
throughout the profile. Alderwood soils are used mainly for tree production and for wildlife habitat and
recreation areas. Less than 30 percent of the acreage is used for growing pasture plants, hay plants, and
diversified farm crops,
Alderwood gravelly loam, 15 to 30 percent slopes
(AmD).- This moderately steep soil is in areas where the rolling upland glacial terraces converge with the
steep drainage way ravines. The surface layer and subsoil are gravelly loam. This soil holds 3 to 6 inches of
water available for plants. Permeability is moderate. Runoff is medium to rapid, and the hazard of erosion
is moderate to severe. This soil is used mainly for tree production and for wildlife habitat and recreation
areas, Capability unit Vie-I; woodland group 3d2.

Belfast Series
The Belfast series consists of well-drained soils on flood plains. Slopes range from 1 to 2 percent. Elevation
ranges from 30 to about 300 feet. These soils formed in alluvium under a forest consisting mostly of
Douglas-fir, western red cedar, Sitka spruce, red alder, maple, willow, cottonwood, salmonberry, and
Sword fern. Annual precipitation ranges from 30 to 70 inches. The average annual air temperature is about
500F, The above 320F growing season ranges from 160 to 200 days, and the above 28'F growing season
ranges from 210 to 250 days. These soils are associated mainly with Lummi and Swantown soils., In a
representative profile in a typical cultivated area, the upper 15 inches is silt loam that is very dark grayish
brown in the upper part and dark grayish brown in the lower part. Below this are dark grayish-brown
stratified layers ranging in texture from fme sandy loam to silt loam. All soil layers are slightly acid except
the surface layer, which is medium acid. Belfast soils are used for growing pasture plants, hay, home
garden crops, bulbs, rhododendrons, and azaleas and for summer home sites.
Belfast silt loam, heavy variant (Bh).- This nearly level soil is on flood plains. The upper 26 inches is
dominantly dark brown or dark yellowish-brown, slightly acid to neutral silt loam. Below this, to a depth of
more than 60 inches, is mostly dark grayish-brown or dark-brown, neutral heavy silt loam and silty clay
loam mottled with dark red and dark reddish brown. Included with this soil in mapping are small areas
having poor drainage. This soil is moderately well drained. Permeability is moderately slow. This soil holds
about 11 to 13 inches of water available for plants. A seasonal water table is at a depth of 2 to 4 feet. Most
of the acreage of this soil is used for permanent pasture, hay, or silage and for many berry, fruit, and
vegetable crops. Capability unit IIw-l; woodland group 302.
Belfast silt loam, wet variant (Bk).-This nearly level soil is on flood plains. The upper 9 inches of the soil
is dominantly very dark brown or very dark grayish-brown, slightly acid or neutral silt loam. Below this, to
a depth of20 inches, is dark-gray or dark grayish-brown, slightly acid or neutral silt loam, fme sandy loam,
or loam mottled with strong brown and dark yellowish brown. Beneath this, and extending to a depth of
more than 40 inches, is dominantly dark-gray or olive-gray, neutral or slightly acid, stratified fme sandy
loam, silt loam, and clay loam. Gravel content ranges from 2 to 25 percent, increasing with depth. Included
with this soil in mapping are small areas where the surface. layer is fine sandy loam or loam. This soil is
poorly drained. Permeability is moderately slow. The soil holds 10 to 12 inches of water available for
plants. A seasonal water table is at a depth of 1/2 to 1 foot. Most of the acreage of this soil is in pasture, but
small areas are used for growing diversified home garden crops. Capability unit IIw-l; woodland group
4w2.
