WETLAND DELINEATION AND ANALYSIS REPORT
Les and Carol Ford
I(ent, VVashington
INTRODUCTION
ALKAI Consultants, LCC. (ALKAI) has been authorized by Dave and Jan Garing on behalf of
Les and Carol Ford to perform a wetland delineation at the property located just west of Lip Lip
Lane on Marrowstone Island, Jefferson County, Washington (Tax Identification Number
977700049). The delineation was performed on May 23, 2007.
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 9, Township 29 North, Range
01 East (Figure 1). The parcel is a 2-acre lot, rectangular in shape, and accessed via Lip Lip
Lane, off of Moen Road on Marrowstone Island, Washington. The parcel is primarily comprised
of a forested plant community dominated by grand fir, western hemlock and Douglas-fir with an
understory of red elderberry, osoberry, salmonberry, and sword fern.
The site is undeveloped and generally undisturbed. The parcel is located on a gentle grade that
gradually slopes to a depression in the northeast portion of the parcel. A wetland was identified
on the parcel, referred to here as Wetland A. Figure 2 illustrates the 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
AlKAI Consultants. llC . 9465 Provost Road NW. Suite 202. Silverdale. Washington 98383

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 Ecology (DOE) Coastal Atlas maps, Washington State Department of
Natural Resources (DNR) Resource maps, Jefferson County Critical Areas maps and Jefferson
County's Critical Areas regulations - Title 18 ofthe Jefferson County Code (JCC).
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 May 23,2007. Fieldwork was conducted under cloudy skies with an ambient temperature of
approximately 55 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

wetland are provided in Appendix C.
BACKGROUND INFORMATION
Watershed
This parcel is located approximately 475 feet west of Puget Sound, three-tenths of a mile
northwest of Lip Lip Point of Marrowstone Island (Figure 1). The Department of Natural
Resources (DNR) map shows a freshwater wetland and an unnamed non-fish-bearing stream
approximately one-half mile to northwest of the subject parcel, which flows into Scow Bay
(Figure 6).
Jefferson County Soil Survey
The soil survey of Jefferson County indicates three onsite soil types:
. CeB Casey silt loam, 0 to 8 percent slopes
. loG Indianola sandy loam, 0 to 15 percent slopes
. Sh Semiahmoo muck, moderately shallow variant
Semiahmoo muck is listed as a hydric soil in Jefferson County. Casey silt loam, although listed
as a somewhat poorly drained soil, is not on the hydric soil list. However an unnamed inclusion
of hydric soil is listed as a possibility in alluvial cones mapped as Casey. The northeastern
portion of the subject parcel is mapped as Semiahmoo muck. Next to this is mapped a band of
Casey silt loam. The remainder of the parcel is mapped as Indianola. A more detailed
description of these 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 not shown on the NWl map. Eleven other
freshwater wetlands are listed on NWI maps within 0.5 miles of the project area (Figure 5). To
the northwest, the NWI map shows the following:
. 2. I-acre PSS/EMA (Palustrine, Shrub-scrub/Emergent, Temporarily flooded) wetland
. 4.0-acre PFOC (Palustrine, Forested, Seasonally flooded) wetland
. O.3-acre PABHx (Palustrine, Aquatic bed, Permanently flooded, excavated) pond
. 0.6-acre PFOC wetland
. 0.8-acre PSSC (Palustrine, Shrub-scrub, Seasonally flooded) wetland
. 1.8-acre PSSC wetland
. 0.2-acre PUBH (Palustrine, Unconsolidated bottom, Permanently flooded) pond
. 0.5-acre PEMC (Palustrine, Emergent, Seasonally flooded) wetland
. OA-acre PEMA (Palustrine, Emergent, Temporarily flooded) wetland
To the southwest:
. 1.0-acre PEMC
. 7 . I-acre PEMA

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 exist 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 southwestern boundary of Wetland A. The wetland extends off of the
subject parcel to the north and east. Wetland A is visible on aerial photos and the approximate
boundary can be inferred from vegetation changes. In general, the wetland is comprised largely
of emergent and shrub-scrub plant communities surrounded by forest. Wetland areas are
dominated by red alder, western red cedar, Pacific willow and western crabapple with an
understory of salmonberry, spirea, lady fern, slough sedge and water-parsley. Approximately
one tenth of the parcel is wetland.
Soils
Soil analysis within the wetland included test pit DP-l near wetland boundary flag A-3 (Figure
2). A peat soil with decomposed wood was observed in the first twelve inches below ground
surface, indicating hydric soils. From twelve to sixteen inches, a mucky loam with low matrix
chroma (Munsell reading 10YR 2/1) was found. This low chroma reading also indicated hydric
conditions. Wetland soil characterization at DP-l was not consistent with that described as
Casey silt loam or Semiahmoo muck in the Soil Survey of Jefferson County Area (USDA 1977).
This data point was located near the edge of the wetland with indicators that were transitional to
upland. Muckier soils similar to Semiahmoo were observed closer to the center of the wetland,
but were not sampled.
Corresponding upland test pit (DP-2) was located slightly upslope near wetland boundary flag A-
4 (Figure 2). The soil to three inches below ground surface was observed to be a loam exhibiting
higher matrix chroma (Munsell reading 10YR 3/2) with no mottles. From three to sixteen inches
below surface, a sandy loam of Munsell reading lOYR 3/4 was found. Upland soil
characterization is consistent with that described as Indianola sandy loam, 0 to 15 percent slopes
in the Soil Survey of Jefferson County Area (USDA 1977). No hydric indicators were found at
DP-2.
Hydrology
Free water was present one inch below the surface at the test pit DP-1. The soil was saturated to
the surface. Fifteen to twenty feet north of the test pit, inundation was approximately 10" above
surface. In addition, the area was a depression with no outlet.

Soils and the area around the upland test pit did not exhibit characteristics of wetland hydrology.
There was no free water in the pit, no inundation, and the soil was not saturated. No other
primary indicators were observed.
Vegetation
The wetland area surrounding the test pit DP-l had vegetation consisting of red alder (Alnus
rubra, F AC), salmonberry (Rubus spectabilis, F AC+), western crabapple (Malus fusca, F ACW),
lady fern (Athyrium filix-femina, F AC), and sword fern (Polystichum munitum, F ACU). Within
the wetland, more than 50 percent of the dominant species were identified as facultative (F AC)
or wetter and therefore meet the wetland criteria for hydrophytic vegetation (Appendix B).
Other wetland vegetation identified nearby included slough sedge (Carex obnupta, OBL), water-
parsley (Oenanthe sarmentosa, OBL), and Pacific willow (Salix lucid a lasiandra, F ACW).
The upland vegetation was distinct from the wetland vegetation.. The upland area surrounding
the test pit DP-2 had vegetation that included red alder (Alnus rubra, F AC), western red cedar
(Thuja plicata, FAC), western hemlock (Tsuga heterophylla, FACU-), grand fir (Abies grandis,
FACU-) salmonberry (Rubus spectabilis, FAC+), red elderberry (Sambucus racemosa, FACU),
salal (Gaultheria shallon, FACU), red huckleberry (Vaccinium parvifolium, NI), lady fern
(Athyrium filix-femina, FAC), and sword fern (Polystichum munitum, F ACU). 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 EVALUATION RESULTS
Wetland Categorization
Wetland A was rated as a disturbed wetland, without irreplaceable ecological functions, greater
than one acre with few invasive species, and of significant habitat value as per Washington State
Wetland Rating System, Western Washington (McMillan 1993). As such, it scored 26 points,
making it a Category II wetland (see Appendix C for rating form). All Category II wetlands
larger than 2,500 square feet are regulated wetlands per JCC 18.15.325. According to JCC
18.15.340 Table 3-4, the standard buffer width for delineated Category II wetlands is 100 feet.
SUMMARY
This wetland report documents the presence of a depressional wetland at parcel 977700049
located at Lip Lip Lane on Marrowstone Island, Jefferson County, Washington. The property is
owned by William and Carol Ford Trustees of Kent. The wetland meets Jefferson County's
wetland classification criteria for a Category II wetland which requires a 100 foot buffer from the
delineated edge. Approximately one third of the parcel is encumbered by buffer or wetland,
however more than one acre of buildable area remains.

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
f'mdings before there is any guarantee of no change. Our estimation for the accuracy of the
unconfirmed wetland boundaries portrayed within this report is ~95%.

Plot Samuline:
A pair of corresponding sample plots was established to determine the wetland area. The
locations of these sample plots (labeled DP-l for the Wetland A test pit and DP-2 for the upland
test pit) 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 F orm (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 (FACW), and/or facultative (FAC) species.
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.

clay films in pores and on faces of peds; moderate organic staining on faces of peds; neutral; abrupt, smooth boundary.
(14 to 24 inches thick)
IIIC1-33 to 40 inches, dark grayish-brown (2.5Y 4/2) loamy fine sand, light brownish gray (10YR 6/2) dry; common, fine,
prominent yellowish-red (5YR 4/6) mottles; massive; soft, friable, nonsticky, nonplastic: few fine roots; neutral; abrupt,
smooth boundary. (0 to 8 inches thick)
IVC2g-40 to 60 inches, gray (5Y 5/1) clay, light gray (5Y 7/2) dry; few, fine, distinct dark-brown (10YR 3/3) mottles; massive;
very hard, very firm, very sticky, very plastic; neutral.
The IIB2tg horizon is silty, clay, or silty clay loam, but in places subhorizons of sandy loam or loamy fine sand are present. In
places coarsetextured glacial drift is below a depth of 40 inches.
Included with this soil in mapping are small areas of moderately well drained and somewhat excessively
drained soils.
This soil is somewhat poorly drained. Permeability is slow. Roots penetrate to a depth of more than 60
inches. This soil holds 8 to 10 inches of water available for plants. Runoff is slow, and the hazard of water
erosion is slight. A seasonal water table is at a depth of 1 to 2 feet. About 60 to 70 percent of the acreage
of this soil has been cleared and is used mostly for pasture. Berries and vegetable crops are of minor
importance. Capability unit lII-w-1; woodland group 4w2.
Indianola Series
The Indianola series consists of somewhat excessively drained soils that formed on eskers or kames in
sandy glacial outwash. Slopes range from 0 to 50 percent. Elevation ranges from slightly above sea level
to 1,000 feet. Native vegetation consists mainly of Douglas-fir, western hemlock, western redcedar, red
alder, rhododendron, huckleberry, salal, Oregon grape, and bracken. Annual precipitation ranges from 26
to 55 inches. The average annual air temperature is 50oF. The above 320F growing season ranges from
about 160 to 260 days, and the above 280F growing season ranges from about 215 to 320 days. Variation
in the length of the growing season at these temperatures depends mostly on elevation, and the soils at
lower elevations have longer seasons. Indianolasoils are associated mainly with Alderwood, Cassolary,
Everett, Hoypus, Kitsap, Quilcene, and Sinclair soils.
In a representative profile in a wooded area, about 5 inches of leaves, needles, bark, and humus cover
the surface. The upper 10 inches of the soil is loamy sand that is very dark grayish brown in the upper
part and strong brown in the lower part. Below this, to a depth of 28 inches, is brown loamy sand.
Beneath this, and extending to a depth of 60 inches, are layers ranging in texture from medium sand to
loamy fine sand.
Most areas of Indianola soils are wooded (fig. 6). Besides production of trees, another important use of
these soils is for permanent and summer rural homesites. Less than 25 percent of the acreage of these
soils has been cleared. This acreage is used for growing various minor crops.
Indianola sandy loam, 0 to 15 percent slopes (loC). This nearly level to strongly sloping soil is sandy loam to
a depth of 8 to 12 inches. Runoff is slow to medium. The soil holds 4 to 6 inches of water available for
plants. This soil is used mainly for producing trees and for wildlife habitat and recreation areas. About 40
percent of the acreage is used for growing such crops as pasture, hay, small grains, berries, and
vegetables. Capability unit. IVe-2; woodland group 302.

Semiahmoo muck (Se).-This nearly level soil is in valley basins. Representative profile 1.5 miles southeast
of Chimacum in SW1/4NW1/4NW1/4 sec. 24, T. 29 N., R. 1 W.:
Oa1-0 to 12 inches, black (5YR 2/1) muck (sapric material), dark reddish brown (5YR 3/2) dry; moderate, very fine, fine, and
medium, granular structure: hard, firm, nonsticky, nonplastic; many roots on surfaces of peds; few fragments of wood;
slightly acid (pH 6,/2) ; gradual, wavy boundary. (8 to 14 inches thick)
Oa2-12 to 16 inches, dark reddish-brown (5YR 2/2) muck (sapric material), dark reddish brown (5YR 3,/2) dry ; weak, fine and
medium, granular structure; hard, firm, nonsticky, nonplastic; about 25 percent sedge fibers that can be identified before
rubbing; common roots on surfaces of peds; slightly acid (pH 6.2); gradual, wavy boundary. (2 to 6 inches thick)
Oa3-16 to 25 inches, brown (7.5YR 4/4) mucky peat (sapric material), that darkens to dark reddish brown (5YR 2/2) upon
exposure to air, reddish brown (5YR 4/4) dry; weak, fine, granular structure; slightly hard, friable, nonsticky, nonplastic;
about 50 percent of mass that, before rubbing, can be identified as leaves and stems of sedges and reeds; slightly acid
(pH 6.2); gradual, wavy boundary. (7 to 12 inches thick)
Oa4-25 to 54 inches, brown (7.5YR 4/4) mucky peat (sapric material) that darkens rapidly to dark reddish brown (5YR 3/3 and
5YR 2/2) upon exposure to air, dark reddish brown (5YR 3/3) dry; fibrous and massive, finely divided; slightly hard, very
friable, nonsticky, nonplastic; about 25 percent leaves and stems that, can be identified before rubbing; medium acid (pH
6.0); abrupt, wavy boundary. (20 to 40 inches thick)
IIC-54 to 55 inches, light-gray (10YR. 7/1) very fine sand and silt volcanic ash, light gray (10YR 7/1) dry; massive; soft, very
friable, nonsticky, nonplastic; medium acid (pH 6.0); abrupt, wavy boundary. (1.2 to 2 inChes thick)
Oa5-55 to 60 inches, dark reddish-brown (5YR 3/4) muck (sapric material) that darkens rapidly, upon exposure to air, to dark
reddish brown (5YR 2/2) and finally to black (5YR 2/1), black (5YR 2/1) dry; massive; hard, very friable, nonsticky,
nonplastic; less than 15 percent wood fibers can be identified; neutral (pH 6.6). In places 1/2- to 2-inch strata (or a single
stratum) of volcanic ash or a 1- to 12-inch layer of light-gray or light brownish-gray diatomaceous earth are present at any
depth in the profile. The organic layers range from medium acid to neutral.
This soil is very poorly drained. Permeability is moderate. Roots penetrate to a depth of 60 inches. This
soil holds more than 10 inches of water available for plants. Runoff is very slow or ponded, and the
hazard of erosion is generally slight or nonexistent. Along banks of open drainage ditches, however,
sloughing and slippage are common. A seasonal high water table is at a depth of 0 to 1 foot. This soil is
used mainly for growing grasses and legumes for hay, silage, and grazing and for growing garden truck
and field crops. Capability unit IIw-2; not assigned to a woodland group.
