The -subject parcel is located adjacent to Chimacum Creek and west of Center Valley Road. The goal of the wetland delineation is to determine wetland locations and associated buffers that would restrict a building site location. All wetlands within Jefferson County are subject to requirements outlined in the Jefferson County Unified Development Code (UDC) dated Janwny 1, 2001. Land use restrictions will apply to all future developments associated with this parcel. Description of Site · Legal Description: Parcel #901142 002 T29N. Rl W, 26 acre parcel · Location: West of Center Valley Road (#408) and South of the Chimacum intersection (Appendix Sheet #1: Location Map) · Soils: HvC Hoypus gravelly loamy sand, Sh Semiahmoo muck, moderately shallow variant. and Se Sem:Jmmoo muck (Appendix Sheet #1: Soil map) . Slopes: 0 to 15% slopes The subject parcel consists of flat pastureland that is actively grazed by llamas. Over half of the parcel consists of low quality wetland that is dominmed by reed canarygrass. The wetland is well defined by a drop in topography and a ditch channeling water from upstream pastures. The ditch empties into Chimacum Creek, which also defines the eastern boundary of the parcel. Applied Methodology The following resomces were consulted for this project: · Jefferson County Critical Areas Map Wetlands (1995) and ESA Maps (Stream and Wetlands) · Aerial Photographs (Soil maps pre-1975, and 2000, included in Appendix) · Jefferson County Unified Developm~nt Code (January 1. 2001) · Soil Smvey of Jefferson County (U.S. Soil COD.SelVation Service 1975) . National Wetland Inventory Map · Washington State Wetland Identification and Delineation Manual · National List of Plant Species That Occur in Wetlands: Northwest (Region 9) Mustin Wetland Delineation Repon File Number 2003-00939 I Olympic Wetland Resources_ Inc. 10/03 Washington State Wetland Identification and Delineation Manual Fieldwork to determine the actual wetland boundaries was conducted according to the methodology outlined in the Washington State Wetland Identification and Delineation Man~ (Departm~ of ..- Ecology #96-94). Chapter 173-.')') of the Washington Administrative Code requires that all wetlands within the State of Washington be delineated using this manual. . The methodology outlined in the Washington State Wetland Identification and Delineation Manual requires e;lClImination of the three parameters for a positive wetland determination: hydric soils. hydrophytic vegetation, and hydrology. For an area to qualify as a jurisdictioDaI wetland it must have a positive indicator nom all three parameters. All wetlands identified usjl)e tbi5 methodology may be federally regulated, regardless of size. Soils A hydric soil is a soil that forms under conditions of saturation, flooding, or ponding lasting long enough during the growing season to result in an anaerobic upper layer. Hydric soils favor the growth and regeneration ofhydrophytic vegetation. The indicators for this type of soil include low chroma, mottles, gleying, and high organic content within the upper 32 inches of the soil profile. Holes were dug on the site and soil colors (including value and chroma) were recorded in the top 16 inches. Soil colors were analyzed using the Munsell Color Charts (1992). Vegetation Wetland plant species must constitute greater than 51 % of the total vegetation present to meet the qualification as a site dom-inlttPil by hydrophytic vegetation. Dominance of plant species is determined by calCliJatine actual aerial cover within a 30-foot radius for trees. a 10-foot radius for shrubs. and ~ 6-foot radius for the herbaceous layer at each data point. Commonly occwring plant species have been rated by the United States Fish and Wildlife Service (USFW) National List of Plant Species That Occur in Wetlands: Northwest (Region 9) as to their frequency of occurrence in wetlands and non-wetlands. During the fieldwork, each species was recorded and given a rating based on indicator status and percent cover. Hydrology WetIand hydrology is defined in the Washington State Wetland Identification and Delineation Manual as "areas that are periodically inundated or have soils saturated to the smface at some time dwing the growing season. ~ Areas must have seasonally inundated or saturated soil at least 12:5% of the ~owing ~ Indicators of~ydrology in~lude visual obsetva~on of inun~.o~:m~--,""\~!tif.'

Wetlands are rated as entire systems and quite often Mustin Wetland Delineation Repon File Number 2003-00939 ") Olympic Wetland Resources. Inc. 10/03 exceed project bOlmdaries ratings: range from Class I to Class IV. Class I is the highest quality wetland and is not replaceable. It therefore receives the largest buffers and highest protection. Streams and Streamside Wetland Definitions According to the DOE Washington State Wetland Rating Syste~ Western Washington (Second Edition DOE Manual). a stream channel is defined as -a seasonal flow of water that is predominately in one direction and there is a defined bank or series ofbanks containing the water. .. Oftentimes, stream and streamside wetlands are intermingled. If a stream has wetland characteristics, no matter how small then the entire system is rated as a wetland. Both streams and wetlands have associated buffers as defined by the Jefferson County Criti~al ^-!eas Ordinance. The larger buffer is the one that is applied. Streams types in Jefferson County are determined using the criteria set forth in the Chapter 122- 16-030 WAC. This system categorizes streams according to connectivity of larger bodies of water, fish bearing potential, use by humans, and whether the stream flow is seasonal or perennial. The ratings range from Type 1, the highest quality, to Type 5, a seasonal non fish- bearing stream. Any vegetated wetland that is contiguous with a stream may be rated separately when it is separated from any other vegetated wetland by a wetland corridor that is less than 50' wide (including the stream channel) for at least 200' (page 59 DOE Manual). Determining Wetland Edges Wetland edges were determined by establishing two data points: one within the wetland which contained positive indicators of all three of the wetland requirements: soils, hydrology. and vegetation., and another data point outside the wetland, where one or all of the requirements were not present. Measurements were taken with a Chainm:m II hip chain. Findings The Jefferson County Critical Areas Map indicates that the parcel is completely within wetland bOlmdaries. Findings indicate that the northeastern portion of the parcel is upslope and well outside the wetland. The wetland edge is clearly defined by a distinct drop in topography and vegetation change, which can even be observed on the aerial map (included in the Appendix). The wetland is very low.quality and consists of a monotypic stand of reed canarygrass. The_ rating for this wetland is a low quality (23 points) Class II wetland. The only reason it qualifies as a Class II rather than a Class ill is because of the connection to Chimacum Creek. Chimacum Creek has been rated as a Type 2 stream and qualifies as a fish-bearing stream. Due to the connectivity of this wetland to this creek. the wetland as a whole will have a shrub and tree lay~r. The vegetation adjacent to the wetland is also connected to a ditch that empties into Chimacum Creek. All wetlands and drainage corridors were flagged with orange plastic ribbon labeled .'Wetland . Boundary, - tied to posts near the drainage ditch at points 10 to 40 feet apart along the wetland edge. The wetland edge is contiguous with the drop in topography and distinrrRegetatioo.--Gl]:anF~~-t:rr;::..l r;D~ ~ (G It u w .~ .ir\-,\\ \ .n \~ . ri - --=-~---=-t \! d \ , Ii)" . }.

The data point locations. wetland edges, and buffers are indicated on the Findings Map in the Appendix (Sheet #2). Soils . Jefferson County Soil Smvey (page 48) lists soils' on site as HvC Hoypus gravelly loamy sand, Sh Semiahmoo muck, moderately shallow variant. and Se Semiabmoo muck. Semiahmoo muck is classified as a hydric soil on the Jefferson County Area Hydric Soil list (Janwuy 1991) and has been mapped throughout Center Valley and. along Cbimacum Creek. Semiahmoo muck consists of very poorly drained organic soil overlying a hard mineral soil formed by glaciers. Data points and soil test pits confirmed the presence of hydric soils; soils were low-chroma the entire depth of the soil test. At Data Point #1 the soil layer was black (1 OYR .211). At Data Point #'. upslope and to the east of Data Point #1, soils colors changed to a higher chroma of dark brown (1 OYR 212 with gravel and rocks and 10YR 212 loamy sand, both with no mottles). Upslope from the wetland, soils are mapped as Hoypus, whi~h is a gravelly soil fOrmed in glacial outwash areas. Several soil test pits were excavated to depths of 6 to 8 feet. near the proposed house site, clearly showing the soil profile. The upper profile of the soil layer consisted of rocks and gravel. Hydric soils were not identified in th~ upper soil horizon. VegetatioD Vegetation diversity is low, consisting of grazed pasture grasses. The only areas where there was tree or shrub layer was near the Chimacwn Creek. Due to the extensive grazing and seasonal dormancy, grass identification was difficult. The reed canmygrasswas obvious since it was not grazed as heavily. Below is the list of vegetation identified and the indicator status.

Hydrology - JEfFERSON COUNTY Water only needs to be present 20 days of the growing season for an area~~~Qig~ . ELOPMENT The growing season i:; defined by the Jefferson County soil survey as March 12 to November 25. Hydrology must be present for 12.5% (20 days) of these 258 days. The growing season is also defined by soil temperature at 19.7 inches below the soil swface being higher than biological 0 (50C or 400F). Daytime temperatures were in the 60's during this fieldwork: therefore this delineation was conducted during the growing season. Mustin Wetland Delineation Repon file Number 1003-00939 4 Olympic Wetland Resources. Inc. 10103 Hydrology was present in the ditch and in Cbimacum Creek. Hydrology was not present in any of the soil test pits dug to 16 inches in depth. When there are positive indicators of wetland soils and wetland vegetation. then hydrology can Pe assumed during the dry seasons. Western Wasbington has been experiencing record drought conditions this year and rainfall has been below normal for 1:he past 3 years. During high water seasons this large wetland has been observed to be completely inundated with water (conversation with Mustin). Classification of Wetlands and Streams All wetlands have been rated according to the DOE rating system. This wetland classifies as a Class IT wetland with 100-foot buffers. All buffers are measured perpendicular from the delineated edge (Jefferson County Unified Development Code, Jan. 1,2001,3-30 Buffers Table 3-4). Cbimacum Creek has been previously classified and mapped as a Type 4 stream, which will also receive 100-foot buffers. The ditch contained standing water to depths of 20". Summary This report presents :findings from the wetland dellD.eation conducted on parcel #901 142 002 in Center Valley owned by Barclay Mustin. Findings reveal a low quality Class IT wetland that is adjacent to Chimacum Creek that is rated as a Type 4 Stream. Both the Type 4 Stream and the Class IT wetland will have associated 100- foot buffers where development will be restricted. The wetland buffer is currently used as pasture land and is heavily grazed. The streamside buffers are partially protected and have a protective tree and shrub layer. The final authority over this wetland determination rests with the governmental agencies: restriction will apply to any development near the wetlands or buffers associated with this parcel.
