1.0 INTRODUCTION
The Property (Site) is a 19.5 acre parcel located at 171 Embody 'Rd in Port Ludlow,
Washington. The Property is listed as Assessor's Parcel #x 821-073-002 and is located in
the Southwest Quarter of Section 17, Township 28 North, Range 1 East (Figures 1, 2, 3
and 4). The property owner is listed as James D. Kelly at 328 Hope Street in Bristol,
Rhode Island 02809-2029.
The property is located in northeastern Jefferson County just west of State Route 19 and
north of Larson Lake Road, The Site covered in this Wetland Delineation includes a single
family home, an existing well, several outbuildings including a barn -type structure, an
existing dock and access driveway.
The property owner intends to place a single family residence on the footprint of the
current structure and install a new septic system on the parcel. Mr. Kelly and Ms. Warrick
contracted with Westech to delineate and rate wetlands on the Site and determine the
buffers required under the Jefferson County Codes (Jefferson County 2014b). Chapter 2.0
describes the Methodology used to conduct this Wetland Delineation, Chapter 3.0 contains
results of the Wetland Delineation.
Field investigations of the wetland were conducted by Mr. Charles Tanner during May 2016.
Dr. Bradford Shea reviewed site conditions and wetland staring, as well as photographic
and other site documentation. Two wetlands were identified on the Site. Both were classified
as Category ill wetlands with habitat ratings of 7, requiring a 110 -foot buffer for projects of
this size, The Wetland boundaries have been marked in the field. Wetland buffer zones
were also staked and marked.

2.0 METHODS
The Wetland was delineated and rated according to procedures required by the Jefferson
County Code (JCC). The JCC requires that wetlands be identified and delineated according
to procedures in the 1997 Washington State Department of Ecology's (WDOE) Washington
State Wetlands Identification and Delineation Manual (Ecology Publication No. 96-94 or as
amended) (JCC 18.22.300). Because the State of Washington now defers to the U. S. Army
Corps of Engineers' (Corps) wetland delineation methods, this wetland was delineated
according to the Corps' Regional Supplement for the Western Mountains, Valleys and Coast
Region (Corps 2010). The Wetland was rated by the methods outlined in the Washington
State Department of Ecology's Wetland Rating System for Western Washington (WDOE
2014).
The following methods are drawn from the Corps' Supplement for the Western Mountains,
Valleys and Coast Region (Corps 2010). The Corps' manual defines wetlands as those
"areas that are inundated or saturated by surface or ground water at a frequency and
duration sufficient to support, and that under normal circumstances, do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions." Wetlands are
defined by the following three criteria:
1. Vegetation: Prevalent vegetation consisting of macrophytes adapted to areas with
wetland hydrologic and soil conditions.
2. Hydric sails: Soils that are histosols, in aquic suborders or that show certain
characteristics associated with poor draining, very poor draining or ponding for a long
duration during the growing season.
3. Hydrology: Evidence that the area is inundated or saturated to the surface between
5 and 12.5 percent of the growing season in most years.
Evidence of at least one wetland indicator from each of these three categories is generally
required to identify an area as a wetland.
Preliminary data gathering consisted of the examining U.S. Geological Survey (USGS)
maps, county parcel, wetlands, and topographic maps, aerial photographs and Natural
Resources Conservation Service (MRCS) soil surveys. Because these sources were
insufficient to make a determination, additional information on site vegetation, soils and
hydrology was unavailable, and the Site did not appear to have the complexity to require a
comprehensive determination, a Routine Determination with Onsite Inspection was used.
WW1482-EmbodyWD.RPT/071916/tjs 6
Because each wetland on -Site was less than five acres, the procedure for "Areas Equal
to or Less Than 5 Acres in Size" was used. The wetlands and their boundaries were
initially estimated by noting likely areas of topographic and vegetative distinction between
wetlands and uplands. The routine method for delineating wetlands begins with the
identification of plant communities, as uplands and wetlands are often occupied by
different assemblages of species determined by combinations of environmental
influences.
These plant communities were identified and evaluated for the presence or absence of
hydrophytic vegetation. The wetland indicator status of the dominant species is used to
determine the presence of hydrophytic vegetation. Each species has an indicator status
defined according to the U.S. Department of Agriculture (USDA) (USDA 2012). A species
indicator status refers to the relative frequency at which the species occurs in jurisdictional
wetlands. Wetland plant species (OBL, FACW and/or FAC) must constitute greater than 50
percent of the dominant vegetation to meet department of Ecology (DOE) criterion for
hydrophytic vegetation (Corps 2010), Because non-dominant plants in the wetland were
scattered irregularly throughout, small transects could not be utilized to estimate percent
coverage. Accordingly, a combination of on -Site visual inspection and aerial maps were
used to estimate percent coverage. These estimates were used to conduct a dominance
test with 50/20 selection as described in the Carps manual (Corps 2010).
Wetland plants were primarily identified in the field, with subsequent collection and keying
when necessary. Plants were identified using the following sources:
Pojar and MacKinnon 1994 (Updated 2004)
Guard 1995
Cooke 1997
Hitchcock and Cronquist 1973
Lyons 1997
Taylor 1995
Keying of plants using magnifying lenses and dissecting microscope was used as
necessary. Determination of wetland indicator status utilized regional keys published by
USDA. This indicator replaced the previous U.S. Fish and Wildlife key in June 2012 (USDA
2012).
Areas with plant communities dominated by hydrophytic vegetation were then evaluated
for wetland hydrology and hydric soils. Wetland hydrology refers to "all hydrological
characteristics of areas that are periodically inundated or have soils saturated to the
surface at some time during the growing season." These are areas with evidence that the
presence of water has an overriding influence on the characteristics of vegetation and
soils due to anaerobic and reducing conditions (Corps 2010). An area has wetland
hydrology if it is inundated or saturated to the surface continuously for at least five percent
(5%) of the growing season in most years. The level of inundation can range from
permanently inundated to irregularly inundated/saturated. The level of
WW1482-Em bodyWD. RPT/07199 6/tjs 7
inundation/saturation can be impacted by precipitation, topography and soil
characteristics.
Hydrology is often the least exact of the parameters used to delineate wetland edges
because it is the most ephemeral and leaves the least reliable traces in the landscape
after water tables or floods have receded. Therefore, indicators of wetland hydrology are
sometimes difficult to find in the field. However, it is essential that a wetland area is
periodically inundated or has saturated soils for a sufficient duration during the growing
season.
Based on Corps recommendations, Westech staff noted areas with evident
characteristics of wetland hydrology. In general, places with wetland hydrology show
evidence that the presence of water has had an overriding influence on characteristics of
vegetation and soils due to anaerobic and chemically -reducing conditions, Hydrologic
conditions were determined through examination of topographic relief and drainage
patterns. Soil moistness was determined by hand and, in the event of standing water, depth
to standing water was noted. Field indicators of wetland hydrology include such features as
watermarks, historic records, and visual observation of saturated soils or inundation.
Evidence of hydric soils was checked along the apparent wetland boundary. These are
soils that formed under conditions of saturation, flooding or ponding long enough during
the growing season to develop anaerobic conditions in the upper layers. These soils are
identified in the field mainly by morphological features such as color patterns, organic
matter accumulation, and observation of inundation.
Soils were sampled to depths of up to 18-24 inches using a wetland shovel. Soil consistency
was determined by feeling for grain size and texture. Soil moisture was determined at that
time. In the event of saturated conditions in the hole, depth to standing water was noted.
Soil color was determined through comparison of field samples with standard Munsell Color
Charts (Munsell 1994). Soil was also examined for presence of redox features, gley or other
indicators of anaerobic soil oxidation. If one or more of these indicators was present in the
wetlands, the soil was considered hydric.
The wetland was determined based on the Routine 0n -Site Field Method used by the Corps
using a combination of vegetation, soil and hydrology indicators. The boundaries of the
wetland were determined by first mapping each plant community area as wetland or non -
wetland. The general wetland boundary was determined by the interface of these two
mapping units, These boundaries were confirmed and the boundary locations narrowed
down by sampling specific transects along wetland boundaries. Various points were
sampled for vegetation, soil and hydrology in order to pinpoint the location of wetland
boundaries. Appendix B contains data forms for two sample points (one wetland and one
upland) from a typical area in the delineated wetland.
Wetland boundaries were indicated in the field by the use of pink "Wetland Delineation
Boundary" flagging tape tied to the wooden stakes (24" or 48") or to trees as appropriate.
All boundaries were staked and/or flagged every 25-30 feet. Buffer widths were determined
W W 1482-E m bodyW D. RPT/071916/tjs
based the Jefferson County Critical Areas Code and marked in the field with orange and
black tape, Soil test pits were indicated by orange/white diagonal flagging and stakes
containing the test pit number..
Site visits were carried out during April and June 2016 by Dr. Bradford Shea. Fieldwork was
conducted during May 2016 by Mr. Charles Tanner in May 2016. This report was prepared
jointly by Mr, Tanner and Dr. G. Bradford Shea. Exploration of the Property involved noting
Site characteristics such as hydrology and soil conditions. A botanical study involving
identification of the plant species found growing on the Site was also conducted. The
wetland edge was delineated and photographic documentation was acquired (Appendix A).
Measurements for mapping purposes were made using a fiberglass tape measure.

3.0 WETLAND DELINEATION RESULTS
3.1 EXISTING CONDITIONS
The property is located in northeastern Jefferson County immediately west of State Route
19 and north of Larson Lake Road. The parcel sits at an elevation of about 160 feet above
mean sea level (msl) in Beaver Valley. The Site includes a single family home, well, barn
structure, several outbuildings, a dock and an access driveway, Forested areas and a
ponded depressional wetland with standing water lie adjacent to cleared on -Site areas.
The northern portion of the parcel is covered in grasses and herbaceous plants, while the
southern portion is forested.
The surrounding area consists of a mix of residential and forested land. A fish -bearing (Type
I~) stream appears on county maps on the parcel to the immediate west, while county maps
show a non -fish -bearing stream (Type N) entering the parcel from the east.
The Property is zoned as Rural Residential 1:10, indicating an allowance of one residence
per 10 acres. Parcels in the surrounding area have residential and forest zoning
designations
Wetlands
Westech's field investigation determined that two wetlands are located on the property. A
large pond, classified as a depressional, ponded wetland (Wetland A) is located in the center
of the property. A depressional, forested wetland (Wetland B) is located on the southwestern
portion of the property and extends onto the adjacent property to the west.
Wetland boundaries were determined by first noting likely areas of topographic and
vegetative distinction between wetland and uplands. The Site vegetation was found to
transition from upland to wetland in a relatively abrupt fashion. Evidence of hydric soils was
checked along the apparent wetland boundary. Westech staff noted the presence of soils
marked by redox features in the boundary areas of each wetland.
Westech staff also noted the presence of hydrological indicators. While difficult to find, and
often the least exact of the three indicators, Westech staff noted areas with evident
characteristics of wetland hydrology, places where the presence of water has an overriding
influence on characteristics of vegetation and soils due to anaerobic and chemically -
reducing conditions. Observed hydrologic indicators included a water table at 10 inches
(Wetland A) and saturation in the rout zone (Wetland B) (See Figure 4 and Appendix B).
WW1482-EmbodyWD.RPT/071916/tjs 10
The vegetation, soils, and hydrology of the Site are described in more detail in the following
subsections. Results of these three factors at four test pits (two in the wetlands, two in the
upland areas) are contained in Appendix B. Figure 5 shows the location of the wetland
relative to nearby features. Site photographs are shown in Appendix A.
V etation
Table 1 a and Table I b list on -Site wetland vegetation and the upland vegetation adjacent
to the wetland boundaries. Both wetlands had tree, shrub and herbaceous layers. Some
areas adjacent to Wetland A had been disturbed and are covered in mixed grasses.
Observations in these areas as well as a forested strip adjacent to the wetland were used
to construct vegetation profiles in this wetland. Wetland B vegetation was that of typical
lowland forested wetland.
Wetland A was dominated in the tree layer by red alder (Alnus rubra, FAC), salmonberry
(Rubes spectabilis, FAC) in the shrub layer and cattail (Typha latifolia, OBL) in the herb
layer. Tables 2a shows the results of a dominance test conducted following the guidelines
of the Army Corps (Corps 2010). This area met U.S. Army Corps criterion for wetland
vegetation.
The adjacent upland area was dominated by red alder in the tree layer, salmonberry in
the shrub layer and tall buttercup (Ranunculus acris, FAC) and Kentucky bluegrass (Poa
pratensis, FAC) in the herb layer. This area also met Army Corps criterion for wetland
vegetation, making hydrologic and soil conditions important for determining wetland
boundaries.
Wetland B was dominated by red aider in the tree layer, salmonberry in the shrub layer
and sword fern (Polystxchum munitum, FACU) and skunk cabbage (Lysicton americanum,
OBL) in the herb layer. Tables 2b shows the results of a dominance test conducted
following the guidelines of the Army Corps (Corps 2010). This area met U.S. Army Corps
criterion for wetland vegetation.
The adjacent upland area was dominated by Douglas fir (Pseudotsuga menziesii, FACU)
and western red cedar (Thuja plicata, FAC) in the tree layer, salmonberry in the shrub
layer and sword fern and common horsetail (Equisitum atvense, FAC) in the herb layer.
This area also met Army Corps criterion for wetland vegetation.

Soils
"Hydric soils" is a name for soils commonly found in wetlands. These soils are identified
mainly by morphological features such as color patterns, organic matter accumulation, or
observation of inundation. A soil may be considered hydric if it is inundated (flooded or
ponded) for at least one continuous week during the growing season in most years (Corps
2010). Westech staff looked for field indicators of hydric soil conditions as recommended
by the Corps. If one or more of these indicators was present in the wetlands, the soil was
considered hydric (Corps 2010).
Westech staff examined existing NRCS soil surveys of the Site. The NRCS maps four
dominant soils on the Site (NRCS 2016). The four soils mapped by the NRCS on the Site
include;
Cassolary sandy loam 0 to 15 percent slope CfC is a well -drained soil associated
with terraces and derived from glacial drift or marine deposits. It has a depth of 20
to 32 inches to the water table and a moderately high capacity to transmit water
(0.20 to 0.57 in/hr). This soil has a moderate water storage capacity in its profile
(about 8.5 inches) and no frequency of ponding or flooding.
Swantown gravelly sand loam (StB1 is a somewhat poorly drained soil derived
from till. It has a depth of about 6 to 12 inches to the water table, a very low to
moderately low capacity to transmit water (0.00 to 0.06 in/hr) and a very low
capacity to store water in its profile (about 2.0 inches). This soil has no frequency
of flooding or ponding.
Alderwood gravelly loam 0 to 15 percent slopes (AmC) is a moderately well
drained soil associated with mills and ridges and derived from glacial drift and
outwash. It has a depth of about 18 to 37 inches to the water table, a very low to
moderately low capacity to transmit water (0.00 to 0.06 in/hr) and a very low
capacity to store water in its profile (about 2.8 inches). This soil has no frequency
of ponding or flooding.
Belfast silty clay loam wet variant L@mI is a poorly drained soil associated with
flood plains and derived from alluvium. This soil has a depth of about 6 to 12 inches
to the water table and a moderately high capacity to transmit water (0.20 to 0.57
in/hr). The soil has a high capacity to store water in its profile (about 10.3 inches),
occasionally floods, and has no frequency of ponding.
Because NRCS soil surveys do not necessarily capture small scale variation, Westech staff
conducted additional field studies of the soils. To examine soils in the wetland boundaries,
Westech staff dug soil pits and observed soil characteristics. The location of two soil pits
examined by Westech is shown in Figure 5. These VSH plots are located within
representative upland and wetland areas. The location of these plots has been marked in
the field using wooden stakes tied with orange and white striped flagging. The soil
information taken at these sample points is highlighted in Table 3.
WW1482-EmbodyWD.RPT/071916/tjs 17
TABLE 3. SITE SOILS
WW1482-EmbodyWD.Tab3/071 91 6/tjs 18
Westech observed both sandy loam and silt loam soils similar to those mapped by the
MRCS. A soil pit in Wetland A consisted of silt Iaams that exhibited a valuelchroma of
2/2(10YR) to a depth of 10 inches and a value/chroma of 611 (10YR) with 20 percent
redox features (5/6 10YR) from 10 to 20 inches. The lower layer of these soils indicated
signs of frequent inundation in the root zone. A soil pit in an upland area exhibited soils
with a value/chroma of 312 (10YR) to a depth of about 10 inches and a value/chroma of
5/2 (1 CYR) with 10 percent redox features (5/6 10YR). This soil also showed signs of
frequent saturation in the root zone. f=eatures of wetland soils made hydrology important
in delineating wetland boundaries in this area.
A soil pit in Wetland B consisted of sand loams that exhibited a value/chroma of 3/2
(10YR) with 20 percent redox features {516 10YR) from 10 to 16 inches. The soil met
Army Corps criterion for Sandy Redox soils. A soil pit in an upland area exhibited soils
with a valuelchroma of 10YR 4/3 to a depth of about 12 inches and a valuelchroma of 3/3
(10YR) to 20 inches. These soils did not meet Army Corps criterion for hydric soils and
did not indicate evidence of frequent saturation in the root zone.
Hydrology
Numerous factors (e.g., precipitation, topography, soil permeability, and plant cover)
influence the wetness of an area. The water source for Wetland A comes from a direct
precipitation, runoff from uphill areas surrounding the wetland and groundwater sources,
Water sources for Wetland B include precipitation, runoff and groundwater sources.
Hydrologic indicators observed in a soil pit in Wetland A included a high water table (10
inches). The soil pit dug in the upland area had no standing water or saturation to 20
inches (Corps 2010), Hydrologic indicators in Wetland B included saturation in the root zone
(10 inches). Adjacent upland soils showed no saturation in the root zone.
3.2 LAND USES AND HABITAT VALUES
Wetlands are transitional areas between upland and aquatic environments where water is
present long enough to form distinct soils, and where specialized, water -tolerant plants grow.
Wetlands serve a variety of functions such as transferring surface water into the ground,
thereby recharging groundwater supplies. Wetlands trap water along with sediments and
pollutants providing storm -water detention and filtration; mitigate flood impacts; and provide
wildlife habitat.
Wetland buffers are important because they reduce the adverse impacts of adjacent land
uses on wetlands. The buffers serve to stabilize soil and prevent erosion, filter suspended
solids, nutrients and toxic substances and moderate impacts of storm -water runoff. As such,
buffers serve to preserve wetland functions. They also provide important habitat for wildlife
living in and around the wetland,
WWI 482-EmbodyWD.RPT/071916/tjs 19
The proximity of the wetlands on the Site to a fish -bearing stream mapped to the west
indicates that the wetlands can play a role in protecting instream water quality. The pond
adjacent to Wetland A is listed in county records as containing fish habitat and likely provides
amphibian habitat because of the presence of hard -stemmed plants that are inundated at
least part of the year. Both wetlands provide habitat for bird and mammal species. Each of
these wetlands provide flood protection capacity due to their close proximity to on -Site and
adjacent properties.
3.3 WETLAND TYPES AND BUFFERS
The buffer sizes to be applied at this Site are governed by the Jefferson County Critical
Areas Code. In order to establish buffer sizes, Jefferson County requires that wetlands be
rated using the Washington State Department of Ecology's Wetland Rating System for
Western Washington (WDOE 2006). In this system, wetland ratings are based on:
1) Water Quality Function (i,e., Does the wetland have the ability to improve water
quality?)
2) Hydrologic Function (i.e., Does the wetland decrease flooding and/or erosion?)
3) Habitat Function (i.e., Does the wetland provide habitat for many species?)
In Washington, wetland rating categories are based on the rarity of the type of wetland, our
ability to replace it, its sensitivity to adjacent human disturbances, and the functions it
performs. The objective of the rating system is to divide wetlands into groups that have
similar needs for protection.
Both on -Site wetlands were classified as Category III wetlands. Wetland A had an overall
score of 19 with a water quality scare of 6, hydrologic score of 6 and habitat score of 7.
Wetland B was rated as having a water quality of 6, a hydrologic scores of 5 and a habitat
score of 7. (See Wetland Rating Forms in Appendix 6), The Jefferson County Codes
require 110 foot buffers to protect these functions in areas of moderate use projects (such
as single family residences). Wetland buffers were flagged in the field with white/orange
striped flagging. The current structure on the property is located well inside the wetland
buffer. Most upland areas adjacent to the residence and seemingly all potential areas for
septic were inside wetland buffers,
3.4 JEFFERSON COUNTY WETLAND MAP
Jefferson County maps a wetland on the central and southern portions of the Site (Jefferson
County 2016). Westech observations confirmed that Jefferson County maps are roughly
accurate in their depiction of on -Site wetlands, though perhaps over -representing the extent
of wetlands on the far eastern portion of the Site. These areas were not examined in detail
due to their distance from the project area (See Figure 4).
WW1482-EmbodyWD.RPT/071916/tjs 20
4.0 CONCLUSIONS AND RECOMMENDATIONS
4.1 CONCLUSIONS
The wetlands were identified and flagged on the Site. Figure 4 shows the location and extent
of the mapped wetlands. This included a depressional pond wetland in the center area and
a depressional forest wetland along the forest edge within the southern portion of the
property. Both wetlands were rated Category III wetlands with habitat scores of 7, Jefferson
County requires buffer widths of 110 feet for this type of wetland and the proposed intensity
of land use for the Site. Wetland boundaries and buffers have been marked in the field.
4.2 RECOMMENDATIONS
Westech recommends that all construction activity for the new septic system tape place
outside the County approved buffer zones. The new home will be built upon the footprint of
the existing house, as allowed by the Jefferson County Code, although it will be constructed
within the wetland buffer.
For these wetlands, buffer zone reduction through buffer averaging or buffer reduction
provisions of the Jefferson County Code may need to be considered to assure project
feasibility. This may include buffer reduction through implementation of a Critical Area
Stewardship Plan (CASP). Westech also recommends that, as feasible, the County obtain
GPS points of the wetland boundaries, or otherwise modify existing County mapping based
on this report, so that the wetland boundaries are accurately reflected in County maps.

`? HGM Classification of Wetlands in Western Washington
For questions 1-7, the criteria described must apply to the entire unit being rated.
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you
probably have a unit with multiple HGM classes, In this case, identify which hydrologic criteria in
questions 1-7 apply, and go to (question F3.
1. Are the water levels in the entire relit usually controlled by tides except dtn•ing floods?
Ut go to 2 YI S - the wetland class is Tidal Fringe - go to 1.1
