As part of a pre-purchase assessment the wetland was delineated to define the wetland edges, analyze wetland categories, and determine associated buffers that would restrict building a single family residence and bams associated with a proposed fann. The delineation was conducted on August 6, 2007. Description of Site . Legal Description: Parcel #901 142001, Section 14 Township 29N Range 1 W . Location: 9 Center Road, Chimacum W A, Jefferson County W A (approximately ~ mile south of the Highway 19 and Center Road four way intersection) · Soils: Se Semiahmoo muck, Th Tisch silt loam, Bk Belfast silt loam, small north east comer is SaB San Juan gravelly sandy loam (all listed as a hydric soil, Jefferson County Hydric Soil List 1/91 except SaB) . Slopes: 0 to 8 percent A map of the site location and mapped soils is included in the Appendix (Sheet #1). Physically the site runs between Chimacum Creek to the west and Center Road to the east. Chimacum Creek is rated as a Type 2 stream with 150' associated buffers and is known to be a salmon bearing stream. The driveway along the entire northern portion defines the northern boundary of the parcel. This parcel was divided in April of2007; land north of the driveway is no long part of this parcel. The site is relatively flat and lies within Center Valley which consists of pasture. Small topography drops define the wetland; a slight rise in topography is the location of the potential building site. Currently there are no structures on the parcel but there was once a fence running north to south that divided the parcel roughly in half. This 23 acre site is approximately 600 feet wide and 1722 feet long along the southern boundary and 1235 feet along the northern boundary. Drainage on the parcel is towards the drainage swale and eventually into Chimacum Creek. The surrounding neighborhood is also in fanns and agricultural land. Williams Wetland Delineation Report File #2007-0806 1 Olympic Wetland Resources, Inc. August 2007 Methodology 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 March 1997). All wetlands within Jefferson County are subject to requirements outlined in the Jefferson County Unified Development Code (DDC) dated January 1,2001. Land use restrictions will apply to all future developments associated with this parcel. A comprehensive description of methodology used to conduct this report is included in the Appendix. RECEIVED Background Information The following resources were consulted prior to field work for this project: . Jefferson County Critical Areas Map (1995) . National Wetland Inventory Map (Included in Appendix with location map) . Aerial Photographs (Soil maps pre-1975 and 2006, 2005, 2000, and internet) . 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) SEP 11 2007 COUNTY oeD Jefferson County Critical Areas Maps show the site to be entirely within wetlands, which is in agreement with the mapped hydric soils. National Wetland Inventory Maps indicate that the northern third to one half portions is outside wetland boundaries. The NWI describes the wetland as a PEMAD Wetland (Palustrine, emergent, temporally flooded/seasonally flooded, and well drained, downloaded from the internet). The Jefferson County wetland Map and the NWI map are included in the Appendix (Sheet #2). ' Wetland Delineation Findings General Wetland Conditions The delineated wetland edge is contained within the low lying areas of a natural swale. Hydrology for this wetland is from surface water from surrounding areas. This wetland is low in habitat value due to few structural layers and only moderate plant species diversity. Large stands of common rush were observed within the wetland, however many species of native wetland dependant species were identified as well. Water from the wetland eventually filters into Chimacum Creek, which is an important salmon bearing stream. This upslope wetland could potentially filter pollutants out of ground water before enteringChimacum Creek. The wetland's edges were flagged with orange plastic ribbon labeled "Wetland Boundary" at points 20 to 30 feet apart. Flagging is labeled with alphanumeric codes (AI through A9). The data point locations, wetland edges, and buffers are indicated on the Wetland Boundary Map in the Appendix (Sheet #3). Williams Wetland Delineation Report File #2007-0806 2 Olympic Wetland Resources, Inc. August 2007 Soils Jefferson County Soil Survey lists the soils as: Se Semiahmoo muck, Th Tisch silt loam, Bk Belfast silt loam, and SaB San Juan gravelly sandy loam in the north east comer. All of these soils are listed as a hydric soil on the Jefferson County Hydric Soil List with the exception of SaB. Field findings within several test pits revealed upland soils within the area mapped as hydric soil. Soils at Data Points 1 and 3 ((DP #1, DP#3) were clearly hydric. At these locations a very dark . brown soils (Munsell 1 OYR 2/2 with mottles 1 OYR 4/4 and 4/6) with abundant mottles were identified. The soils were a mineral soil but had very high fiber content. Soil pits in the upland at Data Points 2 and 4 (DP #2, DP#4) were a lighter brown in color even when moistened. There were 4" rocks found in DP#4 which may be a sign of imported soils. The soils did not qualify as wetland soils even though faint mottles were present due to the higher matrix chroma (Munse1l10YR 2/3 and 3/3 with mottles). Additional soil test pits were dug on the site. These pits are outside the potential building envelope. Soil one soil test pit (STP#1) to the east of the delineated wetland and near Center Road had hydric soils. Soils within many of the test pits were clearly upland soils (STP#2, DP#2, and DP #4). Soil pitswere excavated in the north east comer of the parcel to test for a septic system location by Bernt Ericsen Excavating Inc. in April 22, 2006. Soil logs from the excavation describe the soils as light brown in color with plant roots to 24 inches. Water within the pits was identified at depths of 32 to 40 inches. During the spring months water would be higher if this were a wetland location. Vegetation Wetland vegetation was dominated by an emergent layer of common rush, lady's thumb, bent grass, and reed canarygrass (only a small patch). At Data Point #1 and #3 the majority (100 percent) of the vegetation was hydrophytic. There was no tree or shrub layer. Upland Data Points #2 and #4 were dominated by a planted pasture grass mixture that includes quackgrass, orchard grass, and bentgrass. At these locations only 10 percent of the vegetation was hydrophytic. Below is the list of vegetation identified on site and the assigned indicator status of each species.

Plants classified according to the Fish and Wildlife Service; 1988,1993 Update Hydrology This wetland empties into Chimacum Creek which had running water. During this time of year seasonal wetlands are completely dry and do not have obvious signs of hydrology. There was no surface saturation, free water in the soil test pit, or inundation within the delineated wetland. There were secondary signs of a seasonally high water table. Water stained leaves and oxidized live roots can verify seasonal hydrology during dry summer months. Wetland Analysis Results Wetland Categorization The onsite wetland was classified using the Washington State Wetland Rating Field Data Form (Department of Ecology #96-94). Based on the number of points (15) this wetland rates as a Category III wetland. The rationale behind this categorization is that the wetland is has little species diversity or habitat value. This wetland does have potential~ 41w~e water quality from surface runoff prior to entering Chimacum Creek.

August 2007 Buffer Requirements In Jefferson County, the standard buffer width for a delineated Category III wetland is 50 feet. All buffers are measured perpendicular from the delineated edge (Jefferson County Unified Development Code, Jan. 1,2001,3-30 Buffers Table 3-4). The proposed single family residence and farm buildings are outside this buffer. Summary A Category III wetland was delineated on the parcel as part of a pre-purchase assessment for Karyn Williams. Although the entire site has been mapped within wetlands and containing hydric soil (Jefferson Critical Areas Map and Jefferson County Soil Survey) areas without hydric soil or water tolerant plant were identified. The National Wetland Inventory Map does not agree with soil or critical areas maps and indicates that the wetland is only within the southern half of the subject parcel. All maps are included in the Appendix. The required 50-foot buffers from the Category III wetland edge will not restrict a proposed building envelope. The building site is indicated on the Wetland Boundary Map. Future building plans include a single family residence and several agricultural buildings that would support a small farm. The delineated wetland is contained within a swale that is directly connected to Chimacum Creek. The distinct differences in soil and vegetation types and topography made the wetland boundary fairly clear. Chimacum Creek has been rated as a Type 2 Stream and has 150' buffers. There are no development plans between the delineated wetland and Chimacum Creek. If the buffers are strictly enforced and extra care is taken to keep livestock away from wetlands the water quality will not be altered by future development. Limitations Wetland status depicted in this report has not been confirmed by a government official, final authority over this wetland determination rests with the governmental agencies. Jurisdictional authority over wetlands rests with the local, state and federal agencies. All information in this report should be reviewed by the appropriate regulatory agencies prior to approval.

Chapter 173-22 of the Washington Administrative Code requires that all wetlands within the State of Washington be delineated using this manual. All wetlands within Jefferson County are regulated according to the Jefferson County Development Code, January 2001 (ODC). Applied Methodology Jefferson County 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 ajurisdictional wetland it must have a positive indicator from all three parameters. All wetlands identified using this methodology may be federally regulated, regardless of size. The subject parcel was initially examined to identify plant communities, potential wetlands, topographic features, hydrology sources, and drainage patterns. It was determined whether human impacts to the site would significantly alter the wetland. Hydrophytic Vegetation Criterion: Wetland plant species must, under normal circumstances, constitute greater than 50% 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 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 given a rating based on indicator status and percent cover. Hydrophytic Soil Criterion: 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 (USDA Soil Conservation Service, 1987). 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). Wetland Hydrology Criterion: 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).

High Quality Natural Wetland la. Human caused disturbances Is there significant evidence of human-caused changes to topography or hydrology or the wetland as indicated by any of the following conditions? Consider only changes that may changes that may have taken place in the last S decades. The impacts of changes done earlier have probably been stabilized and the wetland ecosystems will be close to reaching some new equilibrium that may represent a high quality wetland. la.l Upland watershed> 1296 impervious la.2 Wetland is ditched and water flow is not obstructed la.3 Wetland has been graded, filled, logged la.4 Water in wetland is controlled by dikes, weirs, etc. la.S Wetland is grazed THIS SITE IS MOWED la.6 Other indicators of disturbance (listed below) lb. Are there populations of non-native plants which are currently present, cover more than 1096 of the wetland, and appear to be invading native populations? Briefly describe any non-native populations and information source(s): le. Is there evidence of human-caused disturbances which have visibly degraded water quality. Evidence of the degradation of water quality include: direct (untreated) runoff from roads or parking lots; presence, or historic evidence, of waste dumps; oilv sheens; the smell of oroanic chemicals; or livestock use. Brleflv Describe: Q.2. Irreplaceable Ecological Functions: Does the wetiand have at least 1/4 acre of organic soils deeper than 16 inches and the wetland is relatively undisturbed; OR have a forested class greater that 1 acre; OR have characteristics of an estuarine system; OR have eel arass f1oatino or non-f1oatino kelD beds? 2a. Bogs and Fens Are any of the three following conditions met for the area of organic soil? 18.1 Are Sphagnum mosses a common ground cover (> 3096) and the cover of of Invasive species (Table 3) less than 10%1 Is the area of sphagnum mosses and deep organiC soils> 1/2 acre? Is the area of sphagnum mosses and deep organic soils 1/4 to 1/2 acre? 18.2 Is there an area of organic soil which has an emergent class with at least one species from Table 2, and cover of Invasive speCies is < 1 0% (see Table 3)? Is the area of herbaceous plant and deep organic soils > 1/2 acre? Is the area of herbaceous plant and deep organic solis 1/4 to> 1/2 acre? 18.3 Is the vegetation a mixture of only herbaceous plant and sphagnum mosses with no scrublshrub or forest classes? Is the area of herbaceous plants. sphagnum, and deep organic solis> 1/2 acre? Is the area of herbaceous plants, sDhaanum, and deeD oraanic solis 1/4 to 1/2 acre? Q.2b Mature Forested Wetlands 2b.l Does SO%of the cover of upper forest canopy consist of evergreen trees older than 80 years or deciduous trees older than SO years? Note: The size of trees Is often not a measure of age, and size cannot be used as a surrogate for age. 2b.2 Does S096 of the cover of forest canopy consist of evergreen trees older than SO years, AND is the structural diversity of the forest high as characterized by an additional layer of trees 20'-49' tall, shrubs 6'-20' tall and a herbaceous groundcover? 2b.3 Does <2S96 of the areal cover In the herbaceousl groundcover layer or the shrub la er consist of exotic s cies?
