The property is located in the NW quarter of Section 26 of Township 28 North, Range 1 E (Figures 1, 2 and 3). The owner is planning to apply to Jefferson County for a building permit for a single family residence. The property at East Fir Street was checked for environmentally sensitive (critical) areas by Westech Company (Westech) and found to be a shoreline property containing a stream drainage and a small wetland area. Mr. and Mrs. Bodker contracted with Westech to delineate the stream and wetland boundaries and determine stream/wetland type and buffer zones. Chapter 3.0 of this report contains results of the delineation. Field investigations were conducted by Dr. G. Bradford Shea and Ms. Julie A. Knott during November 2006. These investigations included investigations of vegetation, soils and hydrologic conditions at the Site. WW1 008EastFirWetDelin.

("j ~ :J 0) u:: 2.0 METHODS Wetlands were delineated in the field based on field methods recommended in the Washinaton State Wetlands Identification and Delineation Manual (WDOE 1997). Wetland rating was accomplished according to the Guidelines of the Washinaton State Wetlands Ratina Svstem (Western Washinaton) (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 (U .S. ACOE 1989). Guidelines and requirements of the Jefferson County Critical 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 18-22 inches using a wetland shovel, a 24 inch 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 Ms. Knott on November 15, 2006. These surveys included identification of plants, wetland habitats, soils and hydrology. 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 WW1008EastFirWetDelin,RPT/121306/mas 5 were sampled for vegetation, soil and hydrology in order to determine wetland boundaries. Appendix A contains Jefferson County's wetland map as well as field data forms for one typical sample point from the non-regulatory wetland and one typical upland area outside of the wetland boundary. 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. WW1008EastFirWetDelin,RPT/121306/mas 6 3.0 WETLAND DELINEATION RESULTS 3.1 Existing Conditions Elevation of the Site ranges from 0-60 feet above mean sea level (msl) on this shoreline parcel. The Site vegetation is composed of typical second growth forest including Douglas fir, alder and western red cedar as dominant plants. The forest areas cover most of the site with the exception of a cleared area roughly 150 feet square located immediately east of the center of the Site and a shrub zone lying immediately east of the cleared area. There are three areas on the Site which were deemed to be potential sensitive areas (Figure 4). The shoreline of Hood Canal forms the Site's eastern boundary. A Type 4 stream lies near the southern boundary of the Site. The cleared area contains some wetland plants and was investigated as a potential wetland area. Data forms taken within and immediately outside this area are shown in Appendix A. Photographs of the Site are shown in Appendix B. The adjacent site to the north contains an existing single family residence and a well (which will be shared by the two properties. That well lies along the north boundary of the Site, roughly 250 feet west of the proposed homesite. Well tests indicated a static level only nine feet below the surface during late October 1993. Soil logs taken at the time of well installation showed that soils were brown to fine loamy sand in the top 60 inches underlain by gravelly clay and silty clays according to the well logs. Veaetation On-site vegetation was found to be predominantly second-growth forest consisting mainly of Douglas fir, red alder and western red cedar. The understory consisted of bracken and sword fern, salal and Oregon grape. A cleared area which graded into a shrub area included facultative wetland plants such as creeping buttercup, soft rush, piggyback plant and salmonberry as well as upland plants such as thimbleberry, Himalayan blackberry and bracken fern. A list of plant species found on the Site is included in Table 1. Soils Soils on the Site are of the Alderwood and Belfast soil series (SCS 1975) with some Kitsap silt loam immediately to the south. These are generally moderately to well drained soils formed on glacial terraces and floodplains. The specific soil types at the Site are: 1) Alderwood gravelly sandy loam (0-15 percent slopes) This moderately steep soil is in places where the rolling glacial upland terraces converge toward ravines and steep drainageways. Runoff is medium to rapid and the hazard of water erosion is moderate to severe. Alderwood soils have a slowly permeable cemented layer at depths of 20-40 inches.

Site Map Showing Wetland Delineation Westech Company 2006 Approximate Scale: 1 inch = 100 feet Source: Northwestern Territories Inc. 1992 2) Belfast silt loam - These are generally well drained soils formed in alluvium. Soils at the site of this type are mapped as Belfast silty clay loam - wet variant which have moderately slow permeability and a seasonally perched water table at depths of 0.5 to 1.0 feet. This variant is poorly drained with moderately slow permeability. 3) Kitsap silt loam (0-15 percent slopes). This nearly level rolling soil is found on terraces and benches. The SCS mapping shows this soil mainly to the south of the Site. This soil is moderately well drained with very slow permeability. Runoff is slow to medium and erosion hazard is slight. On-site soils were sampled on the edge of the forest area and in the cleared area within the small apparent wetland. Forest soils appeared to be well drained as evidenced by the presence of upland plants and an open test pit (from drainfield testing) containing well drained sandy soils. There was no water standing in the base of the test pit following intense rainfall for more than 12 hours. Within the cleared area, some soil saturation was observed at depths of 8-12 inches below a compacted layer of dark grey/brown soil. These shallow compacted soils vegetated by facultative plants appeared to occupy an area approximately 80 x 90 feet in extent (7,200 square feet). Below the dark soil, we found orange sand at depths of 12-30 inches. HvdroloQV Hydrology of the Site is that of an eastward facing slope draining upland hills to the west. Most of the area is forested with upland forest and appears to be well drained. A stream runs from west to east across the eastern portion of the property, draining through a culvert into Hood Canal. There is a five foot drop from the culvert outlet near a cut in the bluff above the beach. Hydrology on the property appears to be highly dependent on soil type. Variation of soils appears to be a major factor responsible for the small wetland area on the Site although past disturbance (timber removal, grading and clearing) may have contributed to the compressed surface soils and consequent near-surface saturation. 3.2 Description of Wetlands There are three potential sensitive areas on the property: 1) Hood Canal Shoreline, 2) an unnamed Type 4 stream and 3) a small apparent wetland area. The Hood Canal Shoreline lies along the eastern boundary. The boundary of that shoreline was identified by delineating the Ordinary High Water (OHW) mark. A Type 4 Stream crosses the property from west to east, flowing along the eastern portion of the Site's southern boundary. Further west, the stream channel lies off-site on the property to the south. A small cleared area lies immediately south of the end of the improved driveway. The central WW1008EastFirWetDelin.RPT/121306/mas 9 portion of this cleared area was found to contain wetland plants, so further investigation of soils and hydrology was conducted. 3.3 Land Uses and Habitat Values The Site is currently an undeveloped property zoned for residential single family use. The Site contains a second growth forest, a stream and a small cleared field area, part of which contains some wetland vegetation. The stream and forest areas on the site appear to provide habitat for small mammals and birds and possibly deer, raccoon and similar species which co-exist well with human development (adjacent houses on East Fir and other nearby streets). The stream on the property appears to be a perennial stream (Type 4) which does not contain fish, due in part to a five foot drop from a culvert near the Hood Canal shoreline. This drop may be smaller at extreme tides, but it appears unlikely that the stream is ever hydraulically connected to Hood Canal. The area of wetland plants appears to be very small and of less than regulatory size (10,000 square feet). The surface soils have borderline characteristics of wetland soils to depths of 6-12 inches, but appear to overlay well-drained sandy soils. Immediately outside this area are well drained soils including sandy loams and sandy silt loams as evidenced by Westech test pits and the open test pits from previous drainfield investigations. A review of Site photographs taken at the time of clearing does not indicate wetland soil characteristics. 3.4 Wetland Types and Buffers The Hood Canal shoreline (Type 1 Water) has been flagged at the OHW mark (above ordinary High Tide) using pink "Wetland Delineation" tape. A 150 foot buffer zone has been flagged using orange and black striped flagging on stakes and vegetation as required by the County regulations. The stream drainage on the Site is a Type 4 stream. This drainage requires a 100 foot buffer extending from the Ordinary High Water Mark (OHWM) of the stream. The stream has been flagged with "Wetland Delineation" flagging at the northern Ordinary High Water Mark and a 100 foot buffer zone has been staked and flagged using orange and black striped flagging. The small apparent wetland area on the Site appears to be a non-regulatory sized Category IV wetland. This wetland appears to originate largely from past disturbance and soil compression during grading and logging which occurred on the Site about three years ago (Bodker 2006 personal communication and Site photographs). The Site vegetation appears to be consistent with that clearing date. Soils below the compressed surface layer appear to be well-drained and soils immediately outside this cleared area appear to be very WW1008EastFirWetDelin.RPT/121306/mas 10 well drained. Our conclusion that the wetland is non-regulatory in size indicates that no buffer is required under the County regulations. We have considered the apparent wetland to be a "problem area" due to its borderline characteristics. Size and location of the shoreline, stream and their buffer zones is shown in Figure 4. The on-site wetland appears to be below the regulatory threshold in size. WW1008EastFirWetDelin,RPT/121306/mas 11 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 Conclusions The Site includes the Hood Canal shoreline, a Type 4 stream drainage and a non- regulatory sized emergent wetland. The apparent wetland was found to be less than 10,000 square feet in size and does not connect to the stream or to other regulated wetlands. Underlying soils below 12 inches in depth were found to be well-drained sandy loams. A buffer zone of 150 feet was mapped from the Hood Canal shoreline and a 100 foot buffer has been mapped for the stream drainage. With a minor adjustment in the location, the planned residence will lie outside of these buffer zones as per Jefferson County regulations (Jefferson County 2001). 4.2 Recommendations Figure 4 shows mapped locations of shoreline, stream and buffer areas found on the Site. Recommended 150 foot and 100 foot buffer zones adjacent to the shoreline and stream respectively have also been shown on Figure 4. No structures, grading, excavating, filling, draining or other activities which may adversely affect the shoreline, stream or regulatory wetlands may be carried out within the environmentally sensitive area or in the buffer zones as per Section 3.6.9 of the Unified Development Code.
