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 January 1,2001. Land use restrictions will apply to all future developments associated with this parcel. Description of Site · L%m~l Description: Parcel 0901 142 002 'iw_gN, R1W, 26 acre parcel · Location: West of Center Valley Road (~408) and South of the Chimacum intersection (Appendix Sheet # 1: Location Map) Soils: HvC Hoypus ~m-avelly loamy san& Sh Semiahmoo muck moderately shallow- variant. and Se Semaihmoo muck (Appendix Sheet #1: Soil map) Slopes: 0 to 15% slopes The subject parcel consists of flat pastureland that is actively ~m'azed by llamas. Over half of the parcel consists of low quality wetland that is dominated by reed canary~m~ass. 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 resources 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 Development Code (January 1. 2001 ) · Soil Survey of Jefferson Coun~ (U.S. Soil Conservation Service 1975) · National Wetland Inventory Map · Washin~on State Wetland Identification and Delineation Manual · National List of Plant Species That Occur in Wetlands: Northwest (Re,on 9) Mustin Wetland Delineation Report File Number 2003-00939 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 metho~:l, ology outlined in the Washington State Wetland Identification and Delineation Manual (Department of Ecology ~96-94). Chapter 173-22 of the Washington Adminisuafive 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 examination of the three parameters for a positive wetland determination: hydric soils. hydrophytic vegetation,, and hydrology. For an area to qualify as a jurisdictional wetland it must have a positive indicator l~om all three parameters. All wetlands identified usingshis_methodolo~: may be federally regulated,, regardless of size. Soils A hydric soil is a soil that forms under conditions of saturation,, floodin~ or ponding lasting long enough during the ~owing season to result in an anaerobic upper layer. Hydric soils favor the ~owth and regeneration ofhydrophytic vegetation. The indicators for this type of soil include low chroma, mottles, gleying, and high or_manic content within the upper 32 inches ofthe 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 constitme ~eater than 51% of the total vegetation present to meet the qualification as a site dominmed by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover vdthin a 30-foot radius for trees, a 1 O-foot radius for shrubs, and a 6-foot radius for the herbaceous layer at each data point. Commonly occurring 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 ~ven a rating based on indicator stares and percent cover. Hydrology Wetland hydrology is defined in the Washington State Wetland Identification and Delineation Manual as "areas that are periodically inundated or have soils saturated to the surface at some time during the ~owing season." Areas must have seasonally inundated or saturated soil at least 12.5% of the Bowing season. Indicators of hydrology include visual observation of in~_~lkmor, so~... ....... sanwanom water-stained leaves, crackina of the soil surface, and/or sediment de simas of hydrology are often absem dmfng the summer and fall months but can t are positive indicators ofhydric soil and hvdrophytic ve~etauon. ' dt?! Nov- Classification t t ..... i~:-'i'~.:.30i-,_ Wetland cate~ofizmion was &termined usin~ the Washin~on State Departmefit '-- ~ -~. (DOt) Wetland Rating System (publication #93-74, A ~ugust 199~), which assi~rrfm~ffffil value to any ~ven wetland according to wetland size, quality of surrounding buffers, vegetation diversity, wetland types, and habitat value. Wetlands are rated as entire systems and quite often Mustin Wetland Delineation Report File Number 2003-00939 Olympic Wetland Resources. Inc. 10/03 exceed project boundaries ratings: range from Class I to Class IV. Class I is the hi~hest 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 W~tland Rating System,. 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 of banks containing the water." Oftentimes, stream and streamside wetlands are intermin~eck 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 Critical Areas Ordinance. The larger buffer is the one that is applieck Streams types in Jefferson County are determined using the criteria set forth in the Chapter 222- 164)30 WAC. This system categorizes streamq 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, hydrolo~', and vegetation,, and another data point outside the wetland,, where one or all of the requirements were not present. Measurements were taken with a Chainman 11 hip chain. Findings The Jefferson County Critical Areas Map indicates that the parcel is completely within wetland boundaries. Finding 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 top%m~aphy and vegetation change, which can even be observed on the aerial map (included in the Appendix). Thc wetland is very low quality and consists of a monotypic stand of reed canary~m~ass. 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 111 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 layer. 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 20 to 40 feet apart along the wetland edge. The wetland echge is contiguous with the drop in topography and ~it, ~f~ ............... ~! mustin Wetland Delineation 3 Ol.~mpic W~. Resol~. t~.

Semiahmoo muck is classified as a hydric soil on the Jefferson County Area Hydric Soil list (January. 1991) and has been mapped throughout Center Valley and along Chimacum Creek. Semiahmoo muck consists of very. poorly drained organic soil overlying a hard mineral soil formed by ~aciers. Data points and soil test pits confirmed the presence ofhydric soils; soils were low-chroma the entire depth ofthe soil test. At Data Point #1 the soil layer was black (10YR 2/1 ). At Data Point #2, upslope and to the east of Data Point #1. soils colors changed to a higher chroma of dark brown ( 10YR 2/2 with gravel and rocks and 10YR 2/2 loamy san& both with no mottles). Upslope from the wetland,, soils are mapped as Hoypus, which is a gravelly soil formed in ~acial 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 the upper soil horizon. Vegetation Vegetation diversity is low, consisting of ~mmzed pasture ~m-asses. The only areas where there was tree or shrub layer was near the Chimacum Creek. Due to the extensive ~m-azing and seasonal dormancy, ~m-ass identification was difficult. The reed canarygrass was obvious since it was not ~m"azed as heavily. Below is the list of vegetation identified and the indicator status.

Hydrology must be present for 12.5% (20 days) o£these 258 days. The ~owing season is also defined by soil temperature at 19.7 inches below the soil surface being higher than biolo~cal 0 (5°C or 40°F). Daytime temperatures were in the 60's during this fieldwork: therefore this delineation was conducted daring the ~owing season. Mustin Wetland Delineation Report File Number 2003-00939 Ol3xnpic Wetland Resources. Inc. 10,03 Hydrology was present in the ditch and in Chimacum Creek. Hydrology was not presem in any of the soil test pits dug to 16 inches in depth. When there are positive indicators of wetlan~t soils and wetland vegetation,, then hydrology can be assumed during the dry seasons. Westem Washington has been experiencing record drought conditions this year and rainfall has been below normal for the 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 II 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 -l-able 34). Chimacum Creek has been previously classified and mapped as a T.vpe 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 delineation conducted on parcel .~-q)01 142 002 in Center Valley owned by Barcla.v Mustin. Findings reveal a low quality. Class 11 wetland that is adjacent to Chimacum Creek that is rated as a Iype 4 Stream. Both the Iype 4 Stream and the Class II wetland will have associated 100-foot buffers where development will be restricte& The wetland buffer is currently used as pasture land and is heavily ~mxzed. 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.

Box 117 Chimacum, WA 98325 Mr. Barclay, It has been called to my attention that there was an error in the wetland delineation report on Parcel 901 142 002. The summary incorrectly identified Chimacum Creek as a Type 4 stream. Chimacum Creek is a Type 2 stream and the ditch that corresponds with the delineated wetland edge is a Type 4 stream. Please replace updated page for you report. There are no changes in the results. Sorry about the error. Sincerely, DiXie Llcw¢llin Cc' Mo-chi Lindblad, Department of Community Development Randy Marx, Environmental Health Hydrology was present in the ditch and in Chimacum Creek. Hydrology was not present in. any of the soil test pits dug to t 6 inches in depth. When there are positive indicators of wetland soils and wetland vegetation, then hydrology can be assumed during the dry seasons. Western Washington has been experiencing record drought conditions this year and rainfall has been below normal for the 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 II wetland with 100-foot buffers. All buffers are measured perpendicular from the delinemed.edge (Jefferson County Unified Development Code, Jan. 1,2001, 3-30 Bu£fers Table 3-4). Chimacum Creek has been previously classified and mapped as a Type 2 stream, which will also receive 100-foot buffers. The ditch has been. mapped as a Type 4 stream, which also receives 100-foot buffers. During the delineation it contained standing water to depths of 20". Summary This report presents findings from thc wetland delineation conducted on parcel #901 142 ~002 in Center Valley owned by Barclay Mustin. Findings reveal a low quality Class II wetland that is adjacent to Chimacum Creek that is rated as a Type 2 Stream. Both the Type 2 Stream and the Class II 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 delineated wetland edge corresponds with a drop in topography and is adjacent tq a ditch that contained flowing water. The ditch has been mapped as a Type 4 stream. A the 100-foot buffer of the ditch is included within the buffer of the Class II wetland. 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. If there are further questions or planning requirements tbr this project please do not hesitate to call. Dixie Llewellin Principal Biologist, Olympic Wetland Resources, Inc.
