The subject parcel is located west of Center Road between Chimacum and Quilcene Washington. The 4.45-acre parcel (Parcel #901 352003) owned by the Richardsons is undergoing lot line adjustments to create a more suitable building location. After combining the additional acreage from Parcel # 901 341 001 and Parcel # 901 352007 the lot will be 10.56 acres. The additional acreage to be added is to the west and north of the Richardson's property. The additional property is indicated on the findings map (Lots B and C). Maps of the site location, soils (as mapped by Jefferson County Soil Survey) and findings are included in the Appendix (Sheet #1 and Sheet #2). Chimacum Creek bisects the Richardson's parcel. This creek is a high quality salmon-bearing stream that has been assigned a Type 2 rating (Chapter 222-16-030 WAC). Type 2 streams automatically have 150-foot buffers (Jefferson County Unified Development Code, UDC, Section 3 Table 3-2) measured perpendicular from both sides of the stream bank. All wetlands and streams within Jefferson County are subject to requirements outlined in the Jefferson UDC dated J anumy 1, 2001. Land use restrictions will apply to all future developments associated with this parcel. Description of Site . Legal Description: Parcel #901 341 001, Section 35, Township 29N, Range 1 W . Location: Approximately 3 miles south of Chimacum . Soils: Mm McMurry and Mukilteo Peat (hydric soils), Ale Alderwood gravelly sandy loam . Slopes: 0 to 15% The procedures for determining the wetland edge are described III detail under Applied Methodology in the Appendix. Richardson Wetland Delineation Report File Number 2005-4329 1 Olympic Wetland Resources, Inc. March 2005 The following resources were consulted for this project: . Jefferson County Critical Areas Map Wetlands (1995) . Aerial Photographs (Soil maps pre-1975 and 2000, included in Appendix) . Jefferson County Unified Development Code (January 1,2001) . Soil Survey of Jefferson County (U.S. Soil Conservation Service 1975) . Washington State Wetland Identification and Delineation Manual . National List of Plant Species That Occur in Wetlands: Northwest (Region 9) Findings The Jefferson County Critical Areas Map indicates a large wetland near the property. Findings reveal that the majority of the wetland falls on the parcel (Lot B) to the west of the Richardson's property. This wetland is associated with the wetland complex along Center Valley and Chimacum Creek. The pOliion of the wetland delineated consists a high quality forested wetland with remnant emergent wetlands in sections of the open mowed field. In general, the delineated wetland edge corresponded closely with the edge defined by the open pasture and the forest. Some ditching was observed on the edge of the pasture but the wetland still extended out into the field in some areas since there were positive indicators of wetland plants, soils and hydrology (see Sheet 2 in Appendix, A6 through AI2). In accordance with the DOE rating system, the large high quality wetland qualifies as Category II (36 points) due to the complexity of the wetland, habitat value, size, and condition and size of buffers. Category II wetlands will have associated 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). The wetland's edges were flagged with orange plastic ribbon labeled "Wetland Boundary" at points 20 to 40 feet apart. Flagging is labeled with alphanumeric codes (AI through AI8). The data point locations, wetland edges, and buffers are indicated on the Findings Map in the Appendix (Sheet #2). Soils Jefferson County Soil Survey (page 51) lists soils within the valley as: Mm McMurry and Mukilteo Peat, Ale Alderwood gravelly sandy loam. McMurry and Mukilteo Peat are listed as hydric soils on the Jefferson County Area Hydric Soil list (January 1991). The soils within the upper pasture correspond to soils described as Alderwood series and the soils within the wetland were black and consisted of peat thereby corresponding with the McMurry soil types. Perk holes to test for septic sites were present within the open pasture. The holes, excavated to 6 feet deep, did not contain hydric soils within the profile or water in the bottom of the pit. Hydric soils were positively identified within the soil test pits along the forest/pasture edge. Data points and soil test pits confirmed the presence of hydric soils in the lower portions of the site. The soils were low-chroma the entire depth of the soil test, indicating frequent saturation Richardson Wetland Delineation Report File Number 2005-4329 2 Olympic Wetland Resources, Inc. March 2005 and a high water table. Data Point # 1, contained black hydric soils (peat soils 10YR 3/1). Data Point #2, upslope and outside the wetland soil colors were not as dark (10YR 3/2 with no mottles overlaying lOYR 4/3) and the plant community changed. The wetland was flagged between Data Point #1 and #2. Data Point #3, within the pasture, also was found to contain positive indicators of wetland conditions. Soil colors were very dark brown to black the entire depth of the soil test pit (10 2/1). Hydric soils were also found on the southern end of the pasture at Data Point #5 (1 OYR 2/1 overlaying lOYR 4/1 with bright mottles 10Y /R 4/6). Vegetation The wetland has a high diversity of native plant species. Upland areas are mostly dominated by pasture grass. The forested wetland has a mosaic of plant communities, structural layers, and habitat features. Small patches of reed canarygrass were present within the wetland within the pasture. The open pasture is mowed regularly, which helps control this species. Below is the list of vegetation identified on site and the assigned indicator status of each species.

March 2005 Hydrology Hydrology was present throughout the wetland as ponded water and surface saturation. Water was seeping into all wetland test pits. Several plant species indicate the presence of year-round water (bur-reed, water parsley, horsetail, taper tipped rush). Summary A I 0.56-acre parcel was examined for Glenn and Lisa Richardson for a potential building site and septic location. This parcel is in the process of a lot line adjustment as shown in the findings map. A high quality Category II wetland was delineated on March 1, 2005. The delineated wetland edge closely corresponds with the forest/pasture boundary. This wetland will have associated 100-foot buffers. The majority of the mowed pasture is upland. The majority of the wetland falls within in the forested area and the buffers fall within the mowed pasture. Wetland buffers will limit the area for the building envelope and septic site location. The only problem species on the site is reed canary grass, which is known to create large monotypic stands in wetlands and out-compete native species. It is recommended to continue mowing the site to control this grass. Other buffers influencing the building location are Chimacum Creek, which has 1 50-foot buffers. The findings map shows the possible building envelope after the buffers have been recorded. The final authority over this wetland determination rests with the governmental agencies.

Data Points All wetland locations and sizes are approximate; to establish exact points a formal survey is required ~ ~ 1- . Applied Methodology 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 Manual (Department of Ecology #96-94). Chapter 173-22 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 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 from all three parameters. All wetlands identified using this methodology may be federally regulated, regardless of size. Soils A hydric soil is a soil that fOlms 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 dominated by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover within a 30-foot radius for trees, a 10- foot radius for sluubs, 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 given a rating based on indicator status 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 growing season." Areas must have seasonally inundated or saturated soil at least 12.5% of the growing season (20 days out of258 days). The growing season is described in Jefferson County by the Jefferson County soil survey as March 12 to November 25. The growing season can also be defined by soil temperature at 19.7 inches below the soil surface being higher than biological 0 (50C or 400F). Indicators of hydrology include visual observation of inundation or soil saturation, water- stained leaves, cracking of the soil surface, and/or sediment deposits. Positive signs of hydrology are often absent during the summer and fall months but can be inferred if there are positive indicators of hydric soil and hydrophytic vegetation. Classification Wetland categorization was determined using the Washington State Department of Ecology (DOE) Wetland Rating System (second edition, publication #93-74, August 1993), which assigns a numerical value to any given 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 exceed project boundaries. Ratings range from Class I to Class IV; Class I is the highest quality wetland. It is not replaceable and therefore receives the largest buffers and highest protection. Determining Wetland Edges Wetland edges were determined by establishing pairs of data points: one within the wetland which contains 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. The wetland edge is flagged between the pairs of points at intervals of 20 to 40 feet. Streams and Streamside Wetland Definitions According to the DOE Washington State Wetland 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 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 Critical Areas 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 222-16-030 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.
