1.0 INTRODUCTION
The property described as Parcel #802261001, located on Snow Creek Road in Jefferson
County, Washington is a 12 acre parcel of land owned by Dr. Ronald Reinhart. The
property is located in the NE quarter of Section 26 of Township 28 North, Range 2 West
(Figures 1, 2 and 3) and consists of Assessor's Parcel #802261001. The owner has
applied to Jefferson County for a building permit for a single family residence, associated
drainfield and a proposed barn/shop building.
The property at 893 Snow Creek Road was checked for Environmentally Sensitive Areas
by Westech Company (Westech) and was found to contain wetlands. Dr. Ronald
Reinhart contracted with Westech to delineate those wetlands and determine wetland
type and buffer zones. Section 3.0 of this report contains results of the delineation.
Parcel maps were obtained from the Jefferson County Assessor, with the latest revision
dated January 5, 2002. Aerial photographs and other maps were obtained on-line from
Jefferson County and from U.S. Geological Survey and other sources. Field investigation
of wetlands was conducted by Dr. G. Bradford Shea and Mr. James McDougall during
November 2005 and February 2006 (Site photographs are shown in Appendix A).

2.0 METHODS
Wetlands were delineated in the field based on field methods recommended in the
Washinqton State Wetlands Identification and Delineation Manual (WDOE 1997).
Wetland rating was accomplished according to the Guidelines of the Washinoton State
Wetlands Ratino System (Western Washinoton) (WDOE 1993, 2004). Methods were
essentially those recommended by the U.S. Army Corps of Engineers for Routine On-Site
Field Method of Delineation of Wetlands (ACOE 1987, 1989). Guidelines and
requirements of the Jefferson County Environmentally Sensitive Areas Code were applied
as applicable (Unified Development Code, Section 3, Land Use Districts 2001).
Wetland plants were primarily identified in the field, with subsequent collection and keying
when necessary. Plants were identified using the following sources:
Cooke 1997
Guard 1995
Pojar and MacKinnon 1994
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
U.S. Fish and Wildlife Service (USFWS 1988).
Soils were determined through field examination. Soils were dug or augured to depths of
up to 18 inches using a wetland shovel, a 24" soil probe and a standard augur. 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 mottles, gley and other indicators of anaerobic soil oxidation.
Hydrologic conditions were determined through examination of topographic relief and
drainage patterns. Soil moistness was determined by hand as indicated above, and in
the event of standing water, depth to standing water was noted.
Field surveys were carried out by Dr. Shea and Mr. McDougall during November and
December 2005. These surveys included identification of plants, wetland habitats, soils
and hydrology. During February 2006, additional fieldwork was conducted in coordination
with the applicant's septic designer. Test pits were dug by backhoe and analyzed during
this field check.

Wetlands were determined based on the Routine On-Site Field Method used by
Washington Department of Ecology and the U.S. Army Corps of Engineers. Wetlands
were determined by a combination of vegetation, soil and hydrology indicators. Specific
transect and quadrat points were sampled along apparent wetland edges. Various points
were sampled for vegetation, soil and hydrology in order to determine wetland
boundaries. Appendix B contains wetland maps and data forms for one typical sample
point from the delineated wetlands.
Wetlands were staked in the field by 24 inch wooden stakes. Wetland boundaries in
forested areas were indicated by use of 'Wetland Delineation Boundary" flagging tape
placed at appropriate points in trees and shrubs. All boundaries were staked and/or
flagged every 20-25 feet. Wetland buffer zones were determined based on field
measurements and regulatory requirements and were staked in the field and marked with
orange and black striped flagging every 40-50 feet.

3.0 WETLAND DEUNEA TION RESULTS
3.1 Existing Conditions
The Site is adjacent to the northwestern shoreline of Lake Leland. The Site has nearly
level soils, with the exception of the northwest side of the property which is fairly steep.
Elevation is roughly 150 feet above mean sea level (msl). There is a small existing
recreational building (one room dwelling) and a small shelter that have been built near the
lake on the east side of the property (Figures 4 and 5). Also located on the east side of
the property is a small boat docl<.
There are two wetland areas on the Site (Figures 4 and 5). The wetland found in the
southeast area of the property is labeled as Wetland A and can be categorized as an
emergent lake-fringe wetland. This wetland has been classified as a Category III wetland
and parallels the lake shore on the south-eastern portion of the Site.
Another Category ill emergent lake-fringe wetland (Wetland B) was found in the
northeastern portion of the Site. This wetland is heavily forested with red alder and
western red cedar dominating the canopy. A diverse shrub and herb layer can be found
that consists of piggyback plant and salmonberry.
A Type 4 stream flows in an easterly direction through the property and empties into Lake
Leland. Approximately 210 feet of the stream-bank has been deforested in the
northeastern portion of the property. Mowed grass and a few other wetland plants border
the stream in this area.
Veaetation
The Site vegetation is composed of typical forested vegetation with large conifers and
shrubs, including western red cedar, Douglas fir, red alder, ocean-spray and sword fern.
Also included are areas of lake-fringe vegetation which consists of wetland plants and
shrubs such as sedges and salmonberry. Wooded wetland areas consist of red alder,
salmonberry, and piggyback plant (For a more detailed list of plants, refer to Table 1).
The forest area covers the majority of the property, with the exception of the eastern
portion of the parcel which includes a mowed grassy area on both sides of the stream.
The northeast portion of this area is planned for new development (single family
residence, drainfield and barn).

Soils
Soils on the Site are of the Alderwood soil series (SCS 1975). These are generally
moderately well drained and usually have a cemented layer 20-40 inches below the
surface. This causes slow permeability and can cause surface water to appear in
depressed areas. These soils were formed in glacial till. The surface layer is typically a
very dark grayish brown, turning to a dark yellowish brown below this to a depth of 12
inches. Textures range from a gravelly fine sandy loam to a gravelly sandy loam.
The specific soil types at the Site are:
1) Alderwood gravelly loams (AI-C). Found on 0-15% slopes. These gravelly
sandy loams have sandy, very gravelly, or cobbly sub-soils and are
moderately well drained. Runoff is slow to medium and the hazard of water
erosion is slight to moderate. Due to the compact glacial till, water has a
tendency to pool up in depressed areas.
2) Alderwood gravelly loams (AI-D). These soils are found on 15-30% slopes.
This soil type has the same general soil texture and layers as AI-C. The
hazard of water erosion is moderate to severe and runoff is medium to
rapid.
The soils on the Site that have 15%+ slopes are well vegetated with native species and it
appears that water erosion or landslides have not occurred in recent years, since trees
which are at least 70 years old are present on those slopes.
Hvdrologv
Hydrology of the Site includes a Type 4 stream that flows in an easterly direction through
the property before draining into Lake leland. This stream had very low flow in November
due to low rainfall, but judging from the width and depth of the stream channel, it appears
that this stream will have substantially higher flows during periods of heavy rainfall.
Wetland A is classified as an emergent lake-fringe wetland and follows the contour of the
lake. At one point near the existing house, Wetland A widens out, creating an area that is
dominated by reed canarygrass (See Figure 5). Wetland B occupies an area near the
proposed home-site and north of the stream. This is a forested lake-fringe wetland.
Hydrology of both wetlands is driven by water seepage along the top of the glacial till
layer, coupled with some lake water in the root zone along the shoreline.

3.2 Description of WetJands
There are two wetlands found on the property. Wetland A borders Lake Leland on the
southeast side of the property. Its average width ranges from 15-25 feet and can be found
at varying widths along the entire southeast portion of the property. Wetland B varies in
width from 25-60 feet and is a forested wetland located on the northeast portion of the
Site. The Type 4 stream flows in to Lake Leland between the two wetlands. The stream
has a channel which fluctuates between 2-5 feet in width and stream-banks 4-6 feet in
height. Small pockets of wetland vegetation are found at intervals along the stream
channel.
Wetland A
The vegetation of Wetland A is typical of an emergent lake-fringe community. Its diverse
plant community includes sedges, salmonberry, and rushes, with reed canary grass as
the dominant species. Not many tree or shrub species are found in this area except for a
few large alders. There is an area south of the existing building where a large patch of
reed canary grass exists.
Wetland B
This wetland lies adjacent to and north of a Type 4 stream and has plant species of both
shrub-scrub and forested wetland communities. In the northern portion of the property,
mature red cedar and Douglas fir dominate the canopy, with sword fern and moss in the
herb layer. Salmonberry, buttercup, piggyback plant, and sedges are found along the
lakeshore and stream bank. Approximately 70 feet beyond (east of) the existing stream
bridge, the stream enters a mowed field where species diversity is low. This field area
continues downstream for about 280 feet. Shrub and herbaceous wetland species are
found along the stream bank near the lakeshore.
3.3 land Uses and Habitat Values
The Site is currently a partially developed property zoned for rural residential
development. The Site currently has a very small recreational dwelling constructed on
the southeastern portion of the property along with a small recreational picnic shelter and
a small boat dock. These structures are most likely used on a periodic basis. Currently,
the cleared northern portion of property is planned for the construction of a house,
drainfield and barn (see Figure 5).

The wetlands on the site appear to provide habitat for small mammals and birds. Larger
animals including black tailed deer inhabit the area as well as waterfowl such as geese
ducks. Both Wetlands A and B may become nearly dry during summer months along the
upper edges. The wetlands appear to be perennial in terms of saturation but generally do
not contain standing water except in some areas immediately adjacent to the lake.
3.4 Wetland Types and Buffers
Two wetlands on the Site were rated as Category III wetlands. These are diverse lake-
fringe wetlands which contain mostly native species. The Site also contains a Type 4
Stream which connects to the northeastern forested wetland. Wetland size and location is
shown in Figure 5. These two wetlands appear to be above the regulatory threshold in
size.
A 50 foot buffer for the Category III wetlands is required for development ofa single family
residence. Striped field flagging indicating that size buffer zone has been placed around
both wetlands A and B.
The buffer zone for a Type 4 stream in Jefferson County is 100 feet. To allow more room
for building purposes, buffer reduction was implemented on the north side of the stream.
Twenty-five (25) feet has been subtracted from the buffer zone downstream and east of
the bridge to create a 75 foot buffer for a linear distance of approximately 300 feet.
Twenty five (25) feet has been added to the buffer upstream from the bridge. extending
the buffer zone to 125 feet for a total linear distance of 300 feet on both sides of the
stream, resulting in buffer averaging areas of 7,500 square feet (See Figure 5). This
tentative buffer averaging must be approved by Jefferson County prior to implementation
of the project.

4.0 CONCLUSIONS AND RECOMMENDA liONS
4.1 Conclusions
Two wetlands were found on the property. Two Category III emergent lake-fringe
wetlands were found to be present as well as a Type 4 Stream with an associated narrow
riparian zone. These wetlands were found to be greater than 10,000 square feet in size
and the wetlands connect with Lake Leland. Buffer zones of 50 feet for the wetlands and
100 feet for the stream have been field-flagged and mapped within 200 feet of the
proposed residence as per Jefferson County regulations (Jefferson County 2001).
Modifications of the stream buffer zone (reductions to 75 feet near the proposed home-
site, offset by increases to 125 feet in the forested area to the north) are proposed for
buffer averaging and have been flagged in the field (see Figure 5).
4.2 Recommendations
Figure 5 shows mapped locations of regulatory wetlands found on the Site.
Recommended 50 and 100 foot buffer zones around these wetlands have also been
shown on Figure 5 as modified by proposed buffer averaging. No structures, grading,
excavating, filling, draining or other activities which may adversely affect the wetlands
may be carried out in the wetland or in the buffer zones as per Section 3.6.9 of the
Unified Development Code.
