The delineation was performed to determine the presence of wetland or stream areas and associated buffers that would impact future use of the site. The subject property is in the SW 1/4 of Section 16, Township 23 North, Range 01 West WM (Figure 1 Vicinity Map). The ownership is 20 acres in size, oriented north to south. The ownership is accessed by an easement via NE Hill Road, which enters the parcel from the south. The property is zoned one unit per 10 acres; and the northern 10 acres is currently occupied by a single-family residence; therefore, the focus of this report is within the southern 10 acres. A building location has been staked in the field, and is located within the southeastern portion of the parcel. The field inspection was concentrated in areas surrounding the proposed building location. For the purposes of federal, Washington State, and Mason County jurisdictional oversight, methodology used for the wetland delineation is consistent with the wetland definition provided in paragraph 25a of the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997). The sections below provide: (1) an introduction to the site; (2) a description of methods used in the field delineation; and, (3)technical results. GENERAL SITE CONDITIONS The property contains a mature forested community of western red cedar, red alder, and big leaf maple. The understory generally consists of sword fern, piggy back plant, himilayan blackberry and salmonberry with interspersed Devils club. The ownership is comprised of undulating topography, which is generally flat along the southeastern portion of the ownership. The proposed building site it positioned within a portion of the flat area. The flat area transitions to a moderate to high-gradient slope (15 to 30 percent) which descends westerly and northerly,toward the Union River and associated floodplain located north and west of the parcel. Raines Wetland Determination&Stream Analysis TWC06-W317 December,2006 Page 2 A swale is located within the steep slope, with a defined channel less than 2-feet wide within the swale. A speculated wetland area is located upslope of the uppermost extent of the defined channel within the swale. The area was identified as a suspected wetland primarily due to it's location within the lowest point of general landscape topography. Vegetation within the speculated wetland area is comprised primarily of Devils club, salmonberry, swordfern, and piggy back plant. Such plants were identified within the known upland areas as well. The ownership is surrounded by low-density single family development. Several existing foot paths and road grades meander throughout the parcel. METHODOLOGY Review of Existing Information Consistent with procedures detailed in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997) (1997 Manual), preliminary information was gathered on the project site prior to the field review and delineation. General information sources included: United States Geological Service (USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) maps, the Soil Survey of Mason County Area, Washington (USDA, 1951), and Mason County's critical areas regulations. Field Delineation Methodology used for wetland delineation was consistent with the technical approaches articulated in the 1997 Manual. This document is the wetland delineation manual that is used in determining wetland areas when applying state and local government regulations under the Shoreline Management Act and the Growth Management Act in Washington State. The extent and location of project site wetlands were determined during field work performed on December 27 h, 2006. Field work was conducted under rainy conditions with an ambient temperature ranging between 30 and 40 degrees Fahrenheit. The time of year and recent precipitation history were considered in assessing the type and extent of wetlands presumed to exist on site. Specific field methodology used in determining the extent and location of wetland areas include: ■ As part of the initial project site reconnaissance, the site was walked to determine the general extent and location of potential wetland areas; ■ Suspect Wetland and known upland sample plots were established in the potential wetland areas and in the adjacent upland area; and PO Box 2854 Belfair,Washington 98528•Cell Phone 360-620-0618.Office Phone 360-372-2421-boad40@peoplepc.com Raines Wetland Determination&Stream Analysis TWC06-W317 December,2006 Pa-ge 3 Data was collected at four sample plot locations within the project area. Data collected at each sample plot were entered onto a Routine Wetland Determination Data Form (Washington State Department of Ecology 1997). Copies of data forms for each sample plot are provided in Appendix A. Stream Evaluation The onsite stream was classified according to the definitions listed in the Mason County Resource Ordinance, which uses the WAC 16.222.031 Interim Water Typing System. Factors that influence stream typing such as channel width, possibility of intermittent dry periods, stream gradient and obstructions downstream that would effect fish migration were analyzed to accurately classify the stream. BACKGROUND INFORMATION Mason County Soil Survey The soil survey of Mason County indicates two onsite soil types (USDA, 1951): Soil type one is identified as: Belfast sandy loam, 0 to 3 percent slopes (Ba).- The Belfast series consists of moderately well drained, slightly to medium acid, brown alluvial soils that lie along smaller streams. During winter the water table is close to the surface, and some areas are flooded during high water. Soil texture and depth to underlying gravel change within short distances. Coarse sand, with or without gravel, is at depths ranging from 2 1/2 to 4 feet. The Belfast soils differ front other alluvial soils of the county mainly in having parent material that was deposited during the Vashon glaciation. Belfast sandy loam, 0 to 3 percent slopes(Ba) soil is mainly along the Tahuya and Union Rivers. It is closely associated with Belfast silt loam and with Juno soils. The soil does not waterlog, and normally it holds enough moisture to mature crops. Soil type two is identified as: Kitsap silt loam, 15 to 30 percent slopes (Kc).- The Kitsap series consists of moderately well drained, light brownish-gray silty soils on undulating to rolling upland benches. They have developed almost entirely' from lake sediments of the Vashon glaciation. The annual rainfall ranges from 45 to 55 inches. Kitsap They are associated with the Alderwood and the Everett soils, but they have neither the hardpan of the Alderwood, nor the gravelly substratum of the Everett soils. Kitsap soils contain well-developed shot. Kitsap silt loam, 15 to 30 percent slopes (Kc) is on hillsides, gullies, and canyons adjacent to other Kitsap soils. It varies more in depth and texture and has more rapid runoff than the other Kitsap soils. A more detailed soil description can be found in Appendix B Mason Soil Survey Text. The Mason Soil Survey map is shown in Figure 4. National Wetlands Inventory The USFWS NWI map (online wetlands mapper) shows two identified wetland area in proximity to the parcel (Figure 3). One wetland is mapped west of the parcel, and is classified by the NWI as [P] Palustrine, [FO] Forested, [A] Temporarily Flooded.

There are no wetlands mapped within the study area. Department of Natural Resources Water Resource The Department of Natural Resources Water Resource Map shows two identified streams in the project vicinity. One salmon bearing stream identified as Union River is mapped within the northwestern portion of the parcel, and runs off site and west of the parcel. One nonfishbearing stream is mapped to drain northerly within the central portion of the parcel, and is mapped to drain into the Union River(Figure 5. DNR Stream Map). WETLAND DETERMINATION RESULTS General Conditions The speculated wetland area the swale was inspected for positive wetland parameters. The area was observed for wetland indicators based on the presence of facultative vegetation within a swale, and the presence of a seasonal stream downslope of the speculated wetland area. 42. t / i §sue= <& ��+...'�.k•. •t ia� Photo 1.

Sample Plot 1 is located on the easternmost portion of the speculated wetland area within the swale. Sample Plot 2 is located within the western portion of the speculated wetland area near the headwater of the seasonal stream. Sample Plots 3 and 4 are located upslope of the speculated wetland sample plots. Soils The test pits in the speculated wetland area exhibited a two-layer soil profile with a matrix chroma 10YR 3/2 to a 10 and 12-inch depth, and matrix chroma 10 YR 4/2 to an 18-inch depth. The soil texture was silt loam and silty clay loam, and the soil was saturated to the surface in both test pits. The soil characteristics were consistent with the mapped soil type, Kitsap silt loam. No hydric soil indicators were present in the speculated wetland area test pits. Upland soil profiles exhibited characteristics similar to the suspected wetland area and consistent with the mapped soil type Kitsap silty loam. The soil pits in revealed a two- layer profile of silt loam. The upland soil profiles were also saturated to the surface in both test pits. No hydric soil indicators were present in upland soil test pits. Hydrology Observed conditions within the speculated wetland area, relative to hydrology, included soil saturation to the surface, free water in the test pits, and the overall drainage pattern. Given the recent rain event, the presence of soil saturation and/or free water in the test pit outside of the growing season is not sufficient to conclude presence of wetland hydrology. Upland test pits exhibited similar conditions of soil saturation and free water in the pits. With the exception of location within the general landscape, no indicators of wetland hydrology were identified. Despite the time of year and recent rain event the majority of the swale was not inundated nor exhibited signs of prolonged saturation or standing water. Vegetation The vegetation within the speculated wetland area is similar to the understory in upland areas, described below. The vegetation is the speculated wetland arae is comprised of shrub and herbaceous vegetation comprised of salmonberry (Rubus spectabilis, FAC+), Devils club (Oplopanax horridus, FAC+), sword fern (Polystichum munitum, FACU) and piggy-back plant(Tolmiea menziesii, FAQ. Upland vegetation is comprised of an overstory of western red cedar (Thuja plicata, FAQ, red alder (Alnus rubra, FAQ and big leaf maple (Acer macrophyllum, FACU); with an understory of salmonberry (Rubus spectabilis, FAC+), sword fern (Polystichum munitum, FACU), Devils club (Oplopanax horridus, FAC+), piggy-back plant (Tolmiea menziesii, FAQ and Himalayan blackberry(Rubus discolor, FACU).

According to the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology 1997), a speculated wetland area must contain indicators for all three wetland parameters to meet positive wetland criteria. Given the speculated wetland area does not meet positive wetland criteria,no regulations apply. Stream Evaluation The identified stream channel originates within the swale west of the speculated wetland area(figure 2). The drainage is inaccessible to fish from the Union River due to its high gradient(greater than 16 percent), and inadequate channel width(less than two feet). Mason County has recently changed the water typing system from the original Types 1,2,3,4 & 5 streams to Types S, F, Np & Ns streams. Although the codes are new, similar criteria are used to define water types. According to the WAC 222-16-030 water typing system, the stream meets criteria for a type Ns stream, because it is a nonfishbearing stream that seasonally flows into the Union River. The water typing system provides the following definition for seasonal nonfishbearing waters previously identified as type 5 waters: "Type 5 Waters" means all segments of natural waters within the bankfull width of the defined channels that are not Type 1, 2, 3, or 4 Waters. These are seasonal, nonfish habitat streams in which surface flow is not present for at least some portion of the year and are not located downstream from any stream reach that is a Type 4 Water. Type 5 Waters must be physically connected by an above-ground channel system to Type 1, 2, 3, or 4 Waters.

Type Ns streams in Mason County require a 75-foot buffer with a 15-foot building setback. A speculated wetland area was observed within the swale, upslope from the uppermost extent of the defined channel. The speculated wetland does not meet DOE criteria for a regulated wetland because of the lack of hydric soils and wetland hydrology.

NOTES: APPENDIX B Soil Survey Text BELFAST SERIES The Belfast series consists of moderately well drained, slightly to medium acid, brown alluvial soils that lie along smaller streams. Their parent material is washed mainly from surrounding areas of Vashon glacial drift. The native vegetation is a mixture of Douglas- fir, cedar, maple, willow, alder, vine maple, swordfern, shrubs, and grasses. During winter the water table is close to the surface, and some areas are flooded during high water. Soil texture and depth to underlying gravel change within short distances. Coarse sand, with or without gravel, is at depths ranging from 2 1/2 to 4 feet. Large areas of any one texture are few. The soils are in small areas, mainly in the northeastern part of the county along the many small streams. In some areas these Belfast soils differ from the Juno soils only in depth to underlying gravel. The Belfast soils differ front other alluvial soils of the county mainly in having parent material that was deposited during the Vashon glaciation. Belfast sandy loam, 0 to 3 percent slopes (Ba).-This soil is mainly along the. Tahuya and Union Rivers. It is closely associated with Belfast silt loam and with Juno soils. The surface soil is brown, friable, weak, granular sandy loath, 0 to 10 inches thick. The color is lighter with increasing depth. The subsurface to 15 inches is slightly lighter colored and a friable sandy loam. Below the depths of 15 to 25 inches is pale-brown, friable, sandy loam subsoil faintly mottled with yellow and rust brown. This material is underlain by stratified, light brownish-gray silt, fine sand, and sand. At depths-of 42 to 50 inches but, in planes at less depth,the silt and sand rest on well-rounded glacial gravel or very coarse sand. The subsoil in areas along Union River normally is more intensively mottled with yellow and stained by iron, and the underlying material is coarse sand rather than gravel. About 100 acres having a loamy sand surface texture were mapped with this soil. The soil does not waterlog, and normally it holds enough moisture to mature crops. Streaks of dried grass indicate places where sand or gravel is fairly near the surface. Use and suitability.-About half the acreage, mainly areas along the lower reaches of the Tahuya and Union Rivers, has been cleared and is farmed along with other soils. The uncleared acreage provides some grazing. Yields are good for the main crops grown-hay, small grains, and pasture. All available barnyard manure should be put on the soil. Yields can be substantially increased through the occasional use of nitrogen fertilizer. Phosphate also improves yields. Other fertilizers are seldom used. The soil has a fairly high inherent fertility. Its use for agriculture is limited because it is in fairly small patches surrounded. In many places, by the shallower Juno soils or by other less desirable soils; because it is fairly difficult to reach; and because the cost of clearing it is high. This soil is in capability subclass IIIs and it is fair for mixed forests. KITSAP SERIES The Kitsap series consists of moderately well drained, light brownish-gray silty soils on undulating to rolling upland benches. They have developed almost entirely' from lake sediments of the Vashon glaciation. The annual rainfall ranges from 45 to 55 inches. The vegetation is a dense forest consisting mainly of Douglas-fir mixed with alder, cedar, and hemlock. The understory is a luxuriant growth of salal, vine maple, willow, and i swordfern. Kitsap soils occur along the borders of inlets and islands of Puget Sound. They are associated with the Alderwood and the Everett soils, but they have neither the hardpan of the Alderwood, nor the gravelly substratum of the Everett soils. Kitsap soils contain well-developed shot. Kitsap silt loam, 15 to 30 percent slopes(Kc).-This soil is on hillsides, gullies, and canyons adjacent to other Kitsap soils. It varies more in depth and texture and has more rapid runoff than the other Kitsap soils. Use and suitability.-Forestry is the best use of this soil because it is steep and dissected. Trees grow well. Erosion is a serious hazard in the absence of a plant cover. The soil is in capability subclass VIe and in site class 4 for Douglas-fir.
