DRAFT Dmrr Reponr WerlaHo axo Weruro Burren Mmcanon PUN BRtttttott Masren Purxeo ResoRr Jerrenson Counw, Wasxrncron Fon Staresmex CoRponanon INTRODUCTION This report presents the Wetland and Wetland Buffer Mitigation Plan (Mitigation Plan) for the proposed Master Planned Resort (MPR) near Brinnon in Jefferson County, Washington. The Brinnon MPR (Master Land Use Application [MLA] 06-87) is situated on approximately 250 acres around Pleasant Harbor and on Black Point and will consist of an l8-hole championship golf course, residentialhousing, a marina and maritime village. GeoEngineers, Inc. (GeoEngineers) was contracted by Statesman Corporation (Statesman) to prepare a Mitigation Plan to compensate for impacts to wetland and wetland buffers as a result of the MPR. This report was prepared utilizing information obtained from site inspections and the Final Environmental Impact Statement (FEIS) (Jefferson County 2007) for the Brinnon MPR. This Mitigation Plan proposes to compensate for wetland impacts with on-site and in-kind wetland creation following the guidelines for compensatory mitigation as outlined in the Washington State Department of Ecology (Ecology) lVetland Mitigation in Washington State report (Ecology 2006a & 2006b), Jefferson County Code (JCC) Chapter 18.22Part 350 Mitigation (Jefferson County 2008) and to meet the condition(s) set forth by Jefferson County for wetlands and buffers (lvII-A 06-87, Ordinance 0l- 0128-08). The local jurisdiction and lead environmental review authority is Jefferson County. REPORT SCOPE Statesman is requesting approval for wetland alteration through Jefferson County and Ecology. Ecology will review this request using administrative orders of the state Clean Water Act (90.48 RCW) under the standards of the 401 Water Quality Certification process (WAC 173-201A). The United States Army Corps of Engineers (USACE) has determined that the on-site wetlands identified in the report titled Pleasant Harbor Marina and Golf Resort lletland Delineation (GeoEngineers 2006a) are hydrologically isolated; and therefore, are not regulated as waters of the United States (Appendix A). The conceptual and final Mitigation Plans prepared by GeoEngineers will comply with the JCC pertaining to wetland protection and mitigation criteria, mitigation conditions of the MLA and Ecology's lletland Mitigation in Washington State: Part 2 Developing Mitigation Plans, which has been approved by the USACE and the United States Environmental Protection Agency. As stated in FEIS Chapter 5, "the wetland mitigation plan will be developed in conjunction with the detailed design phase of the project and will be required at the outset of the grading plan in advance of final plat approval and project development when details of the construction will be available." This Mitigation Plan was compiled based on site topography, on-site field reconnaissance and a review of preliminary development plans. This Mitigation Plan strictly covers conditions and plans as they relate to wetland alteration. There are five streams located within the MPR and buffer mitigation plans have been developed for those streams in a separate Habitat Management Plan (HI!P) produced by GeoEngineers in conjunction with this report (Habitat Management Plan, Brinnon Master Planned Resarl (GeoEngineers 2008)). FileNo. I2677-001-06 August 21,2008 Page 1 GeoExetxeensiQ ! DRAFT PROJECT LOCATION The Brinnon MPR is located along the western shoreline of the Hood Canal surrounding Pleasant Harbor and on Black Point in Sections 15 and 22 of Township 25 North, Range 2 West of the Willamette Meridian. The MPR property, herein referred to as the site, consists of 13 parcels (50215-2005, -2012, - 2013, -2014, -2015, -2016, -3002, -3003, -3020, -3021, -3022, -3023 and -4002) and is approximately 1.5 miles south of Brinnon in Jefferson County, Washington (Figure l-Vicinity Map). The site is located in the Skokomish-Dosewallips Water Resource Inventory Area (WRIA 16) and is part of the East Olympic and Hood Canal Basins. The 252.4 acre site (15.2 acres of Washington State Department of Natural Resources [DNR] Lease) is partially developed and comprised of three main development sections as identified in Figure l. Section I is approximately 220 acres on Black Point, which extends east approximately I mile into Hood Canal, and was historically used as the Pleasant Harbor RV Park. Sections 2 and3 consist of approximately 35 acres, 15 of which are aquatic and leased from the DNR, and are located on the northwest shoreline of Pleasant Harbor which is a shallow cove of Hood Canal north of Black Point. Currently, Sections 2 and 3 are being utilized for a variety of purposes including business (real-estate office), recreational (the marina) and commercial (restaurant and convenience store). PROJECT DESCRIPTION Statesman intends to develop a mixed-use resort development on the 252.4 acre site south of Brinnon, Washington. Section I of the proposed development (sometimes referred to as Black Point Properties) will consist of an lS-hole championship golf course, club house, residential facilities and associated amenities. Sections 2 and 3 will include the Maritime Village, associated amenities and marina. Photographs of the three sections are located in Appendix B-Site Photographs. Section I is the proposed site for an l8-hole championship golf course that will contain an approximately 60,000-square-foot resort center including a restaurant, conference center, spa, pro shop, and offices. This section will also contain a community center, water treatment plant and ponds, and 802 seasonal and permanent residences. Based on draft plans, the completed golf course resort will consist of roughly I I percent impervious surfaces,6l percent will consist of pervious surfaces and 28 percent would be left undisturbed with native vegetation. Sections 2 and3 are composed of approximately 20 acres located in between Highway l0l and Pleasant Harbor. These sections will contain commercial facilities that will provide a variety of uses and 88 permanent and seasonal residential dwellings. The proposed development in Section 3 will utilize existing impervious surfaces by developing within the footprint of the existing structures to the great€st extent feasible. As part of this development, the existing septic tanks and pump house will be replaced with a sewage treatment plant and water treatment system. The fuel containment tanks and pump will be replaced with a new fuel system. A new one-way entrance access from Black Point Road to the Maritime Village area will be developed and the current marina access from Highway l0l will become a one-way exit. The existing marina will be retained with no plans for expansion, although several existing wooden docks and docks with Styrofoam billets will be replaced with concrete docks as part of a tunicate eradication plan (described in detail below). Based on draft plans, the roughly 20 acres in Sections 2 and 3 will consist of approximately 22 percent impervious surfaces, 5 percent pervious surfaces and 73 percent would be left undisturbed with native vegetation. File No. I 2677-001 -06 August 2 I, 2008 Page 2 GeoExetxeeesiQ DRAFT PROPOSED MITIGATION PROJ ECT Mrrrcarrox PRo.lecr Descrupnon The MPR will incorporate an on-site water treatment and recycling program into the layout of the golf course and residential dwellings in Section l. The on-site water program will impact one wetland (Wetland B) which will be used as a control pond for the water treatment system. This pond will collect water from the MPR and recycle for use by the golf course inigation system. The on-site recycling of water will decrease the amount of fresh water necessary to operate the Golf Course. This pond will also be used as a driving range for golfers. Wetland B is described in detail in the report entitled Pleasant Harbor Marina and Golf Resort Wetland Delineation (GeoEngineers 2006a). Wetland B is located at the bottom of a large kettle in the center of Section l. A kettle is a geologic landform created from receding glaciers that were buried by glacial outwash. Once the glacier melted, a large depression was created were the glacier once resided. Statesman is proposing to partially fill and collect recycled water within this kettle; thus, impacting Wetland B at the bottom of the kettle. The fill will impact 20,693 square feet (0.475 acres) of Category III scrub-shrub wetland and its corresponding buffers. Both Ecology and Jefferson County have set their wetland mitigation ratio for creation to offset impacts to Category III wetlands at 2:l (creation: impact). The purpose of this report is to provide a Mitigation Plan for the compensatory creation of new wetland features and wetland buffers as well as the enhancement of existing wetland buffers on-site and in-kind. The wetland categorization presented in this report differs from what is presented in the 2006 wetland delineation report (GeoEngineers 2006a) due to the adoption of a new Jefferson County critical areas ordinance (JCC Chapter 18.22) in March of 2008. The new JCC requires the use of Ecology's 20M Washington State l{etland Rating System for Western Washington (Ecology 2004). GeoEngineers biologists re-rated Wetland B using Ecology's 2004 rating system and concluded that it is a Category III wetland as presented in Appendix C-2004 Westem Washington Rating Forms. An overview plan of the proposed MPR depicting the golf course layout, buildings, maritime village, marina and critical areas is presented in Figure 2. Statesman is planning to begin construction of the MPR in the summer of 2009 but there is no set end date for construction activities. This Mitigation Plan will be implemented prior to the filling of Wetland B and the anticipated start date for the mitigation construction activities is also the summer of 2009. The approximate time period for construction of the mitigation wetlands and buffers is four months. The proposed project sequencing will occur as follows: o Mobilization to the mitigation site, o Fill and grading of the mitigation site to desired grades, e Planting of identified mitigation vegetation species, o Revegetation of the disturbed areas, . Enhancement of existing wetland buffers, and o Cleaning up and demobilization from the mitigation site. File No. 1 2677-00 I -06 August 21, 2008 Page 3 GeoExetxeeaslQ DRAFT DescRrpnoN oF rxe Deveuopuenr Srre Wetland B is located at the bottom of a large kettle in the center of Section I as shown in Figure 3. The kettle is approximately 140 feet deep with moderately steep slopes that were formed in glacial till. The catchment basin for Wetland B is approximately thirty times the size of the wetland and the main source of hydrology comes from precipitation and localized surface run-off within the catchment basin. Wetland B is listed on the National Wetland Inventory NWI) map (United States Fish and Wildlife Service 1987) as presented in Figure 4-National Wetland Inventory Map, but is not located within a Federal Emergency Management Agency 100-year floodplain. There are two other wetlands (Wetland C and D) located within the boundaries of Section I as shown in Figure 3. These two wetlands are discussed in detail in the wetland delineation report (GeoEngineers 2006a) and neither of the wetlands will be adversely impacted by construction activities. All of the wetlands identified onsite were determined to be isolated wetlands and not federally jurisdictional as outlined in the jurisdictional determination from the Corps of Engineers dated March 27,2007 . Photographs of Wetlands B, C and D are shown in Appendix B - Site Photographs. Wetland B is densely occupied by native scrub-shrub and emergent wetland vegetation. Vegetation within Wetland B is dominated by false lily-of-the-valley (Maianthemum dilatatum. FAC [Facultative]), slough sedge (Carex obnupta, OBL [Obligate]), hardhack (Spiraea douglasii, FACW [Facultative Wet]) and juvenile red alder trees (Alnus rubra, FAC). The wetland buffer is intact and consists of moderately steep slopes with a multi-layer second growth forest dominated by Douglas ftr (Pseudotsuga menziesii, FACU [Facultative Upland]) and westem hemlock (Tsuga heterophylla, FACU) with an understory of westem sword fem (Polystichum munitum, FACU), salal (Gaultheria shallo,n, FACU), red huckleberry (Vaccinium parvifolium, FACU) and evergreen huckleberry (Yaccinium ovatum, UPL [Upland]). Section I contains many sanitary stations that were historically used for RV Park patrons. They are currently abandoned and there is one located at the top of the kettle. There are no structures located in the kettle and an old logging road is the only path leading down the slopes to Wetland B. There are no known historical land uses or structures associated with the site or adjacent parcels; however, a cultural resources monitoring program will be in place during construction activities in case historical artifacts are encountered. ASSESSMENT OF THE IMPACTS AT THE DEVELOPMENT SITE There are three wetlands located on the site but only Wetland B will be impacted from the development activities. Wetland B is 20,693 square feet in size and the entire wetland is being proposed for fill. Waren Recrue Seasonal precipitation and localized run-off is the primary source of hydrology for Wetland B. The moderately steep slopes of the kettle capture water as it falls into the basin and directs it into bottom of the kettle. Signs of inundation in Wetland B include marks of ponded water up to two feet on vegetation, water stained leaves, adventitious roots and buttressed tree trunks. Other signs of hydrology included signs of saturation within 12 inches of the surface specifically including oxidized rhizospheres, low- chroma soils and hydrophytic vegetation. Hydrology appears to be present on a seasonal basis starting in the late fall and ending in the spring. The wetland loses its ponded water during the late spring and summer months but still retains saturation within l2 inches of the soils surface. The kettle that Wetland B resides in will be filled with water and the water level will be governed for use in the water recycling system and the golf course driving range. The kettle and pond will still collect the File No. I 2677-001-06 August 21,2008 Page 4 GeoExeneeas-.1Q I ! DRAFT same amount of direct precipitation from the site. The water in the filled kettle will be incorporated into the irrigation system for use on the golf course. Filling Wetland B with water will create a larger, deepwater hydrologic feature that can be used as habitat for waterfowl and amphibians. Sorr-s Hoodsport-Grove very gravelly sandy loam is mapped within the Wetland B (Figure 5-Soils Survey Map). This soil is generally found in upland areas and is associated with glacial till that typifu the surrounding landscape (United States Department of Agriculture [USDA] 1975). Hoodsport-Grove very gravelly sandy loam is a moderately well drained soil type and is not listed as hydric on the Jefferson County Hydric Soils List (USDA 2001). The soils within Wetland B will be covered with an impermeable layer and then water will be filled in the kettle to the desired level. Veceranott Wetland B is classified under the Cowardin Rating System (Cowardin et al. 1979) as a Palustrine scrub- shrub wetland and is currently undeveloped. The scrub-shrub layer of the wetland is primarily comprised of hardhack and juvenile red alder. The herbaceous layer is comprised of false lily-of+he-valley, slough sedge and miscellaneous grasses. Douglas fir, westem hemlock, western sword fem, salal, red huckleberry and evergreen huckleberry occupy the steep slopes in the upland portion ofthe kettle. The kettle has been historically logged and the existing vegetation is approximately 50 years old. A query of DNR Natural Heritage Features list revealed no presence of rare or sensitive plants on or within the vicinity of Wetland B (DNR 2008). The construction of the control pond for the water treatment system in the kettle will require the removal of vegetation on the slopes and within Wetland B; therefore, vegetation in Wetland B and its corresponding buffer will be removed. Faura Wetland B contains seasonal open water and emergent and scrub-shrub vegetation for food, hiding cover and shelter that currently supports a variety of wildlife species including mammals, birds, reptiles and amphibians. During our field visits, we observed numerous bird species as well as tracks and signs from various wildlife species such as black-tail deer and coyotes. Wetland B is not directly connected to streams, tributaries or other wetlands that could provide habitat for fish species. A review of a Washington Department of Fish and Wildlife (WDFW) Priority Habitat and Species (PHS) map (WDFW 2008) shows no presence of critical habitat or sensitive species on or within the vicinity of the development site. The report titled Pleasant Harbor Marina and Golf Resort Fish and Wildlife Habitat Assessment (GeoEngineers 2006b) described the fish and wildlife presence and habitat quality on and within the vicinity of the site. The filling of Wetland B and corresponding buffer will result in the loss of habitat primarily used by birds, mammals and reptiles but in return will create additional habitat for waterfowl and amphibians. LIHoscIpE PosITloN AND GEoMoRPHoLoGY Wetland B is positioned at the bottom of the watershed and collects precipitation runoff from the slopes surrounding the kettle. Hydrologic input enters the wetland but does not directly discharge back into the watershed due to its depressional and isolated nature. It was classified by both the Cowardin System (Cowardin et. al. 1979) and the Jefferson County four-tiered rating system that corresponds to the 2004 Ecology rating system as shown in Table l. Wetland B is rated as a Category III wetland within an area planned for a high intensity land use and a high score for habitat value. A copy of the 2004 Ecology rating form for Wetland B is located in Appendix C. File No. I 2677-001-06 August 21,2008 Page 5 GeoExetxeeeslQ ! DRAFT Table 1.

The results of the functional assessment for Wetland B are presented below in Table 2. Table 2. Functional Assessment of Wetland B Note: NA=Not Wetland B is a depressional closed system that does not provide the opportunity for functioning in several of the assessment categories shown as NA in Table 2. Wetland B has high index scores for the water quality functions that filter and remove sediment and nutrients, as well as a high density of scrub-shrub vegetation that filten run-off. The catchment area to wetland area ratio is a factor in the lower score for removing heavy metals and run-off, as the highest index value is attributed to wetlands that provide that function for catchment areas that are many times larger. The surrounding land use is relatively undisturbed giving the wetland unit a lower value for water quality functions. Groundwater recharge function is high, due to the capture of all precipitation and direct connection to the groundwater table.

The sunounding forested areas, which will be removed when the kettle is filled, contribute significantly to this score. Native plant richness provides moderate function, but the overall size of the wetland results in a moderate score in functional capacity for mammals. The wetland also serves a moderate habitat function, particularly for wetland-associated birds and mammals, by providing a small refuge for animals that are being displaced from surrounding habitat as it is developed. BurreRs The Jefferson County designated wetland buffer for a Category III wetland with high impact land use and a high habitat function score is 150 feet from the edge of the wetland. The buffer surrounding Wetland B is occupied by a multi-layer second growth forest with relatively little invasive species. This buffer is undisturbed and serves as a wildlife corridor and also as habitat for numerous bird, mammal, and reptilian species. The 150-foot buffer surrounding Wetland B will be cleared of vegetation to accommodate the proposed water recycling system and driving range. MITIGATION APPROACH Current regulatory policies accentuate the importance of providing mitigation for loss of wetland function resulting from development. Typically, mitigation consists of creating, enhancing and restoring wetland areas either on-site, off-site, in-kind or out-of-kind, wetland banking or any combination of these. This report has been prepared to describe the on-site and in-kind compensatory wetland mitigation actions proposed by the applicant. Ecology's publication entitled Wetland Mitigation Washington State: Agency Policy and Guidance (2006a) states that "the first step of any project impacting wetlands should be to avoid impacts to wetland and aquatic resources to the maximum extent possible." The l8-hole championship golf course at the MPR has the goal of reducing water consumption by recycling treated water into the golf course irrigation system. To achieve this goal, Statesman plans to construct several stormwater control ponds to supply the on-site water recycling facility. Because of the limited area due to the proposed golf course and topography, Wetland B will be filled with water in order to create one of these stormwater confiol ponds. Since the goal of the MPR is to limit water consumption by reclaiming golf course and stormwater run- off, there is limited altemative land to create control ponds the required size, thus the impact to Wetland B cannot be avoided. Ecology further states that if avoidance of wetland impacts cannot be achieved, then wetland impact minimization should be considered (Ecology 2006a). Due to the limited land area of the MPR, the impacts to the wetland feature could not be minimized through redesigning the project. Instead, Statesman included this feature as a part of the design for the water treatment and recycling system to take advantage of the natural landform. The depressional, kettle landform will need minimal grading to accomplish the planned control pond at that location. In addition, the water collected at this site is part of a plan for reuse in the golf course irrigation system and result in an overall decrease of water consumption by the MPR. To offset the fill of Wetland B, Statesman is proposing compensatory mitigation in another large kettle south of the Wetland B kettle. Jefferson County replacement ratios, based on Ecology's (2006a) document, were utilized to determine the amount of wetland creation required and forms the basis of the preparation of this plan. It is the overall mitigation goal of this project to provide no net loss of wetland functions, values or acreage as a result of development. Mitigation will be on-site and in-kind through wetland creation. File No. I 2677-001-06 August 21, 2008 Page 7 GzoExetxezeslQ DRAFT The table below outlines Jefferson Counties and Ecology's replacement ratios recommended for wetland impacts to Category III wetlands. In order to strive to achieve a higher replacement ratio than required, this project proposes to create 0.95 acres (41,400 square feet) of forested and scrub-shrub wetland to compensate for 0.475 acres (20,693 square feet) of wetland fill. The wetland creation number was derived by evaluating the mitigation site and potential creation areas. Table 3. Jurisdictiona!

Seven potential wetland mitigation areas were identified for on-site and in-kind mitigation. All seven of the potential mitigation areas are located within the boundaries of the site in Section l. After a review of updated MPR layouts, six of these wetland mitigation areas were removed from consideration due to spatial constraints from geomorphic landforms, available hydrology, golf course fairways, residential dwellings and lack of space for a suitable buffer. The following sections discuss the baseline conditions at the preferred mitigation site. DescRlpnoN oF Mrrrcaron Anea The preferred mitigation option is located in the bottom of a kettle, referred to as Kettle C, similar to the kettle that Wetland B is found in. Kettle C is located approximately 800 feet south of Wetland B in the south central portion of Section I (Figure 3). The bottom of the kettle is hydrologically isolated and there are no wetlands or streams located in this landform. The walls of the kettle range from 30 to 55 percent slope and are approximately I l0 feet tall. There are paved roads surrounding the kettle at the top of the slope and vegetation has been cleared within the past l0 years in the entire kettle unit. Wetland creation in this area would be on-site and in-kind (depressional and hydrologically isolated). HISTOnIc AND CURRENT LAND USE Kettle C has been historically logged and the most recent logging event occurred in the past ten years. The RV Park historically had campsites and roads surrounding the kettle but the kettle itself was never used for any commercial or recreational purposes. There are no man-made structures located in the kettle but there are sanitary stations associated with the RV Park located near the top of the slope. Since this File No. I 2677-001-06 August 21,2008 Page I GeoExeueenslQ ! DRAFT kettle is also located on-site, the zoning and land use are the same as Wetland B. An aerial photo depicting the condition and land use of the kettle in 2005 is presented in Figure 6. Werlero FearuRes There are no wetlands associated with Kettle C. No wetland features, streams or seeps were observed entering or leaving this mitigation area. Thus, the area identified as Kettle C is located in an upland portion of the site. Weren Recrme Hydrology is the most important component of any wetland creation project. Hydrologic characteristics are the dominant modifiers of wetlands and exert great control over the type of vegetation. Kettle C receives hydrology from direct precipitation and localized runoff from the catchment basin surrounding the kettle depression. There is no direct outlet in this depressional area and there were no signs of inundation or hydric soils in the bottom of the kettle. The high infiltration rate of the soils in this area does not allow water to collect and pond on top of the ground or within 12 inches of the surface for more than l2 percent of the growing season. This kettle does not lie within a 100-year floodplain. Sorr-s The ^Soil Survey of Jefferson County (USDA 1975) has identified one soil type being associated with the location of Kettle C. The mapped soil is Hoodsport - Grove very gravelly sandy loam (HrD) as shown in Figure 5. Hoodsport-Grove very gravelly sandy loam, 0 to 30 percent slopes, is a moderately well drained soil formed from glacier outwash. Permeability is moderately rapid and available water capacity is very low. This soil is not a listed hydric soil for Jefferson County but the soil does have unnamed hydric inclusions (USDA 2001). A confining layer was not observed within 16 inches of the surface that would slow water moving through the various soil layers. Veoemnor The vegetation in the bottom and sides of the kettle is primarily composed of juvenile red alder, Douglas fir, sword fern and miscellaneous grasses. Mature vegetation was removed from logging activities less than ten years ago and the existing vegetation is indicative of upland plant communities. A query of DNR Natural Heritage Features list revealed no presence of rare or sensitive plants on or within the vicinity of Kettle C (DNR 2008). Fauna Kettle C does not have the potential to support a variety of wildlife species (birds, reptiles, and mammals) due to the disturbed forest and shrub layer and the presence ofa paved road surrounding the top ofthe kettle. There is also no aquatic habitat to support amphibians or attract birds. This area is not directly connected to undisturbed portions of habitat on-and off-site; and therefore, fauna are not assumed to utilize this area frequently. During field visits, only a few bird species were observed in this area. There are no streams or tributaries connected to this mitigation area that could provide habitat for fish species. A review of WDFW PHS maps (WDFW 2008) shows no presence of critical habitat or sensitive species on or within the vicinity of Kettle C. The report titled Pleasant Harbor Marina and Golf Resort Fish and Wildlife Habilat Assessment (GeoEngineers 2006b) described the fish and wildlife presence and habitat quality on and within the vicinity of the site. This mitigation area will be incorporated into the File No. I 2677-001-06 Augast 21, 2008 Page 9 GeoExeneztsiQ DRAFT HMP which outlines the preservation and creation of wildlife corridors and habitat features that will be featured in the final design of the MPR (GeoEngineers 2008). LauosCepE PoSITION AND GEOMORPHOLOGY Kettle C is located in a kettle that is approximately ll0 feet deep with moderately steep slopes. There is no potential outlet to this kettle. The bottom of this kettle is located at elevation 83 feet mean lower low water (MLLW) and the top of the kettle is located at elevation about 195 feet MLLW. The catchment basin for this area begins at the top of the slope surrounding the kettle. These conditions were confirmed during our site visits. Burrens The buffer area in this kettle is disturbed from logging activities and portions of the outer edge are disturbed from the development of the RV Park. There were only a few observations of Himalayan blackberry (Rubus discolor) and Scot's broom (Cytisus scoparius) observed in the buffer area. The buffer area is primarily composed ofjuvenile red alder, Douglas fir, sword fem and miscellaneous grasses. DESCRIPTION OF MITIGATION SITE PLANS The preferred area of wetland creation is shown in Figure 7. The following sections describe the concepts of the mitigation plan for creating wetland conditions at this mitigation site. The mitigation wetland, after creation, would receive direct precipitation, surface run-off similar to Wetland B and treated stormwater for its source of hydrology. The projected goal is to create a wetland mitigation site that meets or exceeds the performance of a Category III scrub-shrub wetland, thus complying with Jefferson County regulations. Waren Reorme Wetland hydrology is referred to as all hydrologic characteristics of areas that are periodically inundated or have soils saturated to the surface for a sufficient duration during the growing season. The growing season is defined as the portion of the year when soil temperatures at 19.7 inches below the soil surface are higher than biological zero (41'F). Areas which are seasonally inundated and/or saturated to the surface for a consecutive number of days greater than or equal to 12.5 percent during the growing season are considered to be wetland. The growing season for Jefferson County is from March to November (usDA 2002). A query was made to gather historical rain data for the area. Quilcene, Washington, a city approximately I I miles north of the proposed site, was the location of the nearest weather station and located in similar geographic and climatic conditions. The data for the Quilcene 2W weather station reveals that station received an average precipitation of 55.24 inches per year, from June 4, 1948 to June 30,2007 (Westem Regional Climate Center 2007). Research of weather stations in Chimacum, Washington (north or the site) and Shelton (south of the site) reveal that precipitation amounts were 29.45 inches and 66.19 inches, respectively, for the similar amount of time. This demonstrates that precipitation levels increase from north to south in the Hood Canal region and because the MPR is south of Quilcene it will likely receive more precipitation than that location. The amount of precipitation recorded at Quilcene for the region is sufficient to support the hydrology needed to sustain wetland conditions because there are three wetlands currently present on the site and all receive direct precipitation and surface run-off as their sources of hydrology. The preferred mitigation site will receive water in the same fashion as well as treated stormwater from the MPR. FileNo.12677-001-06 August 21,2008 Page I0 GeoExetxeeaslQ DRAFT The preferred mitigation site will be supplied hydrology from reclaimed water run-off from the MPR. It will be required that the run-off from the golf course pass through a water treatment system before entering the newly created wetland or existing wetlands. The amount of hydrology entering the created wetlands, and existing wetlands, will likely be greater than the existing site conditions because of the addition of reclaimed water. Due to the increased hydrology entering the wetlands, the newly created wetland should have soils that remain saturated for a sufficient duration of the growing season to achieve hydric wetland conditions. Additionally, ponding may occur and provide increased value to the wetlands' function due to an open water component. The groundwater table in Kettle C is at a depth too far below the surface to consider excavating to in order to create a wetland fed with groundwater hydrology. Thus, direct precipitation, surface water runoff and treated stormwater are the best candidates to add hydrology to this proposed wetland. Sots The soil type present in Kettle C is moderately well drained and does not favor wetland creation; thus, Kettle C does not contain wetland features due to the porous nature of the soil (USDA 1975). Soils rich in silt and clay have a lower permeability and higher water capacity than sandy and gravelly soils. Therefore, the addition of imported soils with clay and clay-like characteristics will be necessary to retain sufficient hydrology to create wetland conditions. The confining soil layer will be added to Kettle C after filling and grading have occurred as described below. Due to the poor water retention of the soil layers that will be underneath the confining layer, the silt and clay layer will need to be five feet deep and tightly packed in order to fill all space within the soil before water can be successfully captured and retained. Once water is able to be retained, hydric soils and hydrophytic plants should occur in the created wetland. During construction events, the top 12 inches of hydric soils will be salvaged from Wetland B and placed on the top layer within the wetland creation area at Kettle C. Importing hydric soils will bring additional benefits to the created wetland such as seed sources, roots and rhizomes of wetland species and may retain micronutrients, mycorrhizae, and other necessary components for plant growth (Ecology 1993a). GRaorNc Putt/Sre Maps The preferred mitigation site will require significant filling and grading to achieve 41,386 square feet of mitigation for the filling of Wetland B. An analysis of the existing grade in Kettle C was performed to determine the cubic yards required to fill the bottom of the kettle to achieve the necessary square footage of wetland surface. It was determined that 13,059 cubic yards of fill and a S-foot deep confining layer will be required to raise the bottom of the kettle from the 83 feet MLLW to 120 feet MLLW as shown in Figure 8. The bottom of the kettle will be compacted and shaped to a concave surface allowing for water to pond; thus, creating 41,400 square feet of wetland within the Kettle. During clearing and grading of Kettle C, the top 2 feet of hydric soil within Wetland B will be excavated and stockpiled for use in the mitigation area. The soils will be transported to the created wetland and spread out with a minimum depth of 6 inches deep on top of the confining layer. The filling and grading plan for the kettle is shown in Figure 8. Pllunrc/LenoscapE PLANs One objective of this mitigation plan is to use native species occurring in Wetlands B, C and D as well as their buffers. Planting should occur in the fall of the same year after the excavation/grading activities have been completed. The created wetland will have an open water component incorporated into the center that will stay ponded throughout the year. The sides of the wetland will experience seasonal File No. 1 2677-001 -06 August 21, 2008 Page 1I GroExcrnerns.1y' I I I T DRAFT inundation correlating with the wet season. The bottom of the wetland will not be deeper than 24 inches than the wetland edge to allow for seasonal herbaceous plants to grow around the edges. Large woody debris will be placed in the open water component as well as along the edges to create habitat for amphibians. Wetland and buffer vegetation was analyzed at Wetlands B, C and D and incorporated into the planting plan. Plants selected for the created wetlands will be based upon their hydrologic requirements, their attributes, such as being able to support wildlife and their ability to improve water quality. Vegetation is a major factor in the distribution of wildlife. Plants provide food, shelter against predators and weather, and areas for nesting, resting, perching and breeding (Leedy et al. 1978). Other areas with existing vegetation that are valuable to wildlife will be maintained within the designed buffer. Plants noted to occur in high quality habitats were selected over plants that form monotypic stands or possess low quality habitat characteristics such as hardhack (Spiraea douglasii). Invasive species at the mitigation site will be removed prior to plant installation. All machinery will be properly cleaned prior to work at the mitigation site to limit fugitive invasive species seeds unintentionally brought onto the site. No soil from the impacted wetland will be incorporated in the mitigation site if it is noted to contain invasive species. Upon invasive species discovery at the mitigation site any time during the project, appropriate measures will be taken to remove it and ensure it does not return. The prefened mitigation site is disturbed but contains native upland vegetation. The intact areas of the surrounding buffer of the created wetland will be left unplanted to allow the existing vegetation to continue to grow. Habitat structures and features at the mitigation site will be installed in the form of new wetland plants, open water components and large woody debris placed in various locations in and surrounding the wetland. Once the MPR is complete, human traffic in the mitigation area will be minimal except for MPR personnel and biologists. Table 5 outlines the vegetative species proposed for planting as well as general size and spacing of each species. A detailed planting plan of the mitigation site is presented in Figure 9 and descriptions of the proposed mitigation plantings are found in Appendix D - Plant Descriptions. Table 5.

Wetland buffers will follow the JCC Chapter 18.22 on critical areas and the created wetland will require a 150-foot buffer for a Category III wetland. This buffer will be preserved and no disturbance activities will occur in this area. Buffers will be measured perpendicular from wetland boundaries and are to be permanently marked in the field by a fence. The buffer for the created wetland is depicted Figure 8. Statesman will secure a deed restriction for the wetland mitigation area and the associated buffers. The area surrounding the preferred mitigation site is dominated by a variety of native and non-native upland plants. In order to increase the value of the buffers for the mitigation plan, non-native vegetation, such as Scot's broom and Himalayan blackberry, will be removed to provide native plant species a better chance of thriving. Native plant species will be re-planted, if upon removal of non-native plant species an area becomes sparsely vegetated. These preserved buffers will not only protect the new wetland, but also serve as habitat for many smaller animals such as, small songbirds, reptiles, and mammals. These buffers will also help to connect wildlife corridors throughout the golf course. In addition to preserving upland vegetation for buffers surrounding the newly created wetland, the portions of the buffers of existing Wetland C and Wetland D will be enhanced as part of this mitigation plan. Details of the wetland buffer enhancement plans are described in the sections below. To accommodate topographic restraints of the site, buffer averaging for Wetland C and D is proposed in discrete locations. A wetland buffer addition will add 28,701 square feet of total wetland buffers to compensate for a total buffer loss of 26,910 square feet. Details of the buffer averaging plan are presented in Figure l0 and described in the sections below. Wetland C Wetland C is a Category III wetland, requiring an 80-foot buffer. Portions of this wetland buffer currently have gravel and paved roads crossing through it breaking up the native vegetation. Along the sides of these roads and in disturbed portions of the buffer, Himalayan blackberry and Scot's broom are also present in thick patches. The impervious surfaces and invasive species will be removed from the buffer and much of this area will be replanted with upland vegetation native to the area. To accommodate the fairway for Hole #2 of the planned golf course, a portion of the eastern wetland bufferdirectlyadjacenttothegolf coursefairwaywillbereduced. Atotal of 8,247 squarefeetofbuffer will be reduced, but there will not be a reduction of more than 25 percent along any portion of the buffer File No. I 2677-00t-06 August 2 l, 2008 Page 13 GzoExetxezeslQ DRAFT as outlined in the JCC 18.22.330.8. The reduced portion of the buffer contains apaved road and large amounts of Scot's broom and Himalayan blackberry to be removed as part of the enhancement plan. The buffer addition area will occur on the northern and southern portions of the wetland and will compensate for the reduction with the addition of 8,316 square feet. The buffer addition area currently consists of mixed coniferous-deciduous forest of Douglas fir, westem red cedar, and red alder. Increasing these areas of forest on the southem side of this wetland will provide more space and assist to better connect the proposed wildlife corridors. Details of the wetland buffer area are shown in Figure I I and a description of plants proposed for the enhancement portion of this buffer is listed below in Table 6. Table 6.

The impervious surfaces and invasive species will be removed from the buffer and much of this area will be replanted with upland vegetation native to the area. The planned fairway of Hole #6 also passes through the western portion of the 15O-foot buffer of Wetland D. This portion of the wetland buffer will be reduced by a total of 18,663 square feet, but will not be reduced more than 25 percent as outlined in the JCC 18.22.330.8.

FACU Salal DRAFT MITIGATION SITE-SPECIFIC GOALS, OBJ ECTIVES AND PERFORMANCE STANDARDS As stated above, this Mitigation Plan strictly covers conditions and plans as they relate to wetland alteration. A HMP with buffer mitigation plans (GeoEngineers 2008) has been developed for the five streams located within the Maritime Village area of the MPR Goels Chances ofsuccess are dependent on a thorough evaluation ofexisting conditions, soils, vegetation, and hydrology of the proposed mitigation site. This mitigation report is focused toward the following goals: o Provide no-net-loss in wetland acreage and function, o Provide on-site, in-kind compensatory mitigation, o Create a total of 0.95 acres (4l,40Osquare feet) of forested, shrub and emergent wetland, o Maintain or enhance hydrologic patterns similar to current conditions at existing wetlands, o Provide a natural plant community within the created wetland area that will surpass the diversity and structural complexity currently found at the mitigation site, and o Perform a wetland delineation of the created wetland area at the end of the monitoring period using the approved wetland delineation manual for that year to verifr that 0.95 acres of wetland was created. Oe.,ecnves Specific objectives and standards associated with this wetland mitigation are: o The creation of 0.95 acres (41,400 square feet) of wetland habitat is pplanned to compensate for the loss of 0.475 acres (20,693 square feet) of Category III wetlands. The mitigation area will be required to meet all three wetland parameters (vegetation, soil and hydrology) at the end of the monitoring period as defined in the monitoring plan. . Vegetate the area using only native plant species occurring in the project vicinity, o Vegetate wetland and buffer areas with species that will provide a broad food base for wildlife or that are high in cover value, o Buffer average along the outer 25 percent of Wetland C and D buffers, . Enhance Wetlands C and D buffers, o Importation of clay-rich soils to line the bottom of wetland creation areas, o Utilize mulch from on-site sources, o Trees of significant value will be flagged prior to construction by a biologist. Construction of the wetland in the vicinity of the existing trees shall leave an adequate physical buffer so as not to damage the roots or the trees. It is assumed that the width of the buffer surrounding the existing trees will be determined by the drip line and on a case-by-case basis. o Use Best Management Practices during construction to protect water quality in adjacent wetland areas, and o Implement a defined monitoring program that will serve as a measure of the mitigation success. File No. 1 2677-001-06 August 21,2008 Page 15 GroExermrrs/ DRAFT GompensnroRY Pl.an Mitigation efforts are proposed to expand and enhance several features identified by wetland biologists as components of high-quality habitat. These features include: . High structural diversity, especially emergent, shrub and forested canopy layers for birds, o Adequate buffers to protect native plants and to provide key components of habitat, o Undisturbed corridors between rivers, streams, wetland systems, intact upland habitats and other natural areas, . High diversity or abundance of native plants and animals, and o Either seasonal or intermittent open water. Many of the above components are planned for incorporation into this mitigation plan. High structural diversity can be achieved by the proposed planting of three canopy layers. Native plants will be planted and desirable native volunteers will be permitted. MONITORING PLAN A specific set of performance standards corresponding to the stated mitigation goals have been established for the MPR. The goals listed in the previous section are implemented below and these standards will be used to judge the results of this project. The success of this mitigation is dependent upon the components specified in this plan. Post-construction monitoring will occur on an annual basis for a minimum of five years and up to ten years based on the success of the project. The limiting factor for success of the project is the size of the tree canopy aerial coverage. Tree canopies may take up to ten years to meet performance standards for this project. Ecology and Jefferson County will determine the success of the mitigation project after five years and conclude how many more years of monitoring will be required before the site reaches performance standards if not successful by year 5. The as-built event will occur following completion of the installation of the vegetative species. This event will document that the created wetland appears to meet the construction plans and document any deviations from the plans. Items to be noted will include: plants were installed as specified and that the wetland appears to be receiving hydrology as planned. At this time, the wetland specialist will aid in the production of the "as-built drawings" and these drawings will be included in the as-built report submitted to Ecology and Jefferson County. Whether the second monitoring event will occur in the spring or in the fall depends on the time of year during which the planting of the created wetland has occurred. The monitoring events will occur at approximately 6-month intervals following the second monitoring event. The primary focus of the annual spring monitoring event will be on hydrologic functions, with the fall monitoring event focusing on vegetative diversity, cover and mortality. A brief monitoring report will be prepared subsequent to each fall monitoring visit summarizing the spring and fall monitoring observations and will be submitted to the appropriate agencies within 3 months of the fall monitoring event. A wetland delineation of the created wetland areas will be performed at the end of the monitoring period to verifu that 0.95 acres of wetland was created. The approved wetland delineation manual for the year of the final monitoring will be followed. A wetland delineation map will be submitted along with the final monitoring report describing the results of the delineation. File No. I 2677-001-06 August 21,2008 Page 16 GeoExatxeetslQ DRAFT Meruoos Producing a photographic log of pre-construction and post-construction environmental conditions will be a primary method of monitoring the success of the mitigation. Observations to be recorded include plant survival and growth rates, hydrologic factors, and wildlife occurrences. Photographs will also be taken at each monitoring event at each monitoring station to document the evolution of the mitigation site over the monitoring period. Photographs will be taken in all four cardinal directions, from the same point, height, and focused in the same direction. a a a a a Six permanent monitoring stations will be established in the wetland creation and wetland buffer mitigation areas. The same standards described below will be implemented in the wetland buffer enhancementareas. Eachmonitoringstationwillconsistof circlewithan ll.8-footradius(0.01 acres) with a reinforcing bar embedded in the center. Selection of monitoring stations will be spaced out in the wetland creation area to accurately depict the different plant species communities and habitat features. Monitoring of each station will be accomplished by determining the survival rate of the planting by counting both dead and live plants of each species respectively within the station. Each species will be recorded by name along with its coverage. Also, the general condition of each plant, such as observations of new growth and signs of stress or disease, will be noted. Monitoring of aerial coverage of the vegetation within the wetland creation area will be accomplished by estimating the percentage of the ground covered within the monitoring station, by planted and volunteer species. Estimating aerial overage will occur during the first monitoring event and also during each monitoring event thereafter. Trees, shrubs and herbaceous species will be included in the estimate of coverage. Desirable native volunteer species will be identified and documented; and undesirable non-native species such as reed canarygmss (Phalaris arundinacea, FACW), Himalayan blackberry (Rubus discolor, FACU), cutleaf blackberry (Rubus laciniatus, FACU, and Scot's broom (Cytisus scoparius, UPL) will be identified, counted and their percentage of aerial coverage will be estimated and compared to performance standards listed below. Upon completion of this documentation, the undesirable species will be removed. Hydrology and presence of hydric soil will be verified by tracking soil saturation or ponding water within the created wetland areas during the spring and fall monitoring events. Thriving obligate plant species will be documented as partial indicators of a successful hydrologic regime. We will also look for hydrology within 12 inches of the ground surface for at least 12 percent of the growing season each year. Wildlife recordings are to be made as general notes by the monitoring biologist during the monitoring events. Observations may include sighting of individual species, nests, burrows, droppings, or other indicators. The results will be recorded, including date and time of day, and included in the report for the monitoring event. Maintenance requirements such as trash removal and vandalism repair will also be noted. These observations, along with mitigation site photographs and a brief report will be submitted to Jefferson County and Ecology after the annual monitoring event is completed. It is understood that in order for monitoring to occur, the biologist will be required to cross the existing wetland and associated buffer in order to enter the mitigation area. Access will be restricted to only authorized personnel, who will be aware of the sensitivity of the existing and created wetland. The landscape contractor will also be made aware of this, and should be careful not to disturb desirable vegetation when removing non-native species. In both instances, trained a a File No. 12677-001-06 August 2 1, 2008 Page 17 GtoExorurns.1y' ! DRAFT professionals who will be able to determine a path of minimal disturbance to the existing wetland should be hired. PeRroRuaNcE STANDARDS a a a a SITE PROTECTION Statesman will protect this mitigation site from disturbance including logging, mining, development and selling of the mitigation areas. MAINTENANCE Plant maintenance of the wetland creation areas will be conducted throughout the monitoring years. Maintenance during the first two years will include periodic watering (irrigation) and control of undesirable species. Maintenance during the subsequent years will be focused on weeding (invasive plant removal). Also, if crowding of newly planted vegetation by grass species is determined to affect plant survival during the monitoring events, the maintenance company will return to trim grasses from around the drip lines of the planted vegetation. Irrigation of the wetland creation area may be required for the first 2 years after installation of native plants. A temporary irrigation system may be utilized or a regular watering schedule established if on-site water is not available. Watering during the plant establishment period is crucial for plant survival. During the dry months, usually June through September, it may be necessary to add up to 3 gallons of water per plant per week. Extremely warm weeks may necessitate watering on a more frequent basis. An irregular watering interval will encourage the development of deep root systems, which in time will reduce the need for any future watering. Control of undesirable species will be maintained by periodic weeding of the mitigation area. Species to be removed primarily include exotic invasive species such as: reed canarygrass, Himalayan blackberry, cutleaf blackberry and Scot's broom. Only desirable native volunteer species in addition to those planned for the area will be encouraged to grow. Wetland buffer slopes will be reseeded with grasses if deemed necessary due to erosion or sedimentation into the newly created wetland areas. Some of the other File No. I 2677-001-06 August 2 l, 2008 Page 18 GtoErctxezaslQ Invasive, exotic and undesirable species shall be represented by less than l0 percent coverage in the created wetland area and buffer enhancement areas at the end of the monitoring period as determined by observations made within the monitoring areas. There shall be a minimum of 80 percent survival of all planted materials throughout the monitoring period. Survival of the enhancement plantings will be determined by counting and documenting the numbers of dead versus live plants within the enhanced area. Species, quantities, general conditions and sizes of enhancement plants will be described and recorded. Acceptable cover standards for the wetland trees and shrubs: . end of year l: minimum of 20 percent . end of year 3: minimum of 30 percent . end of year 5: minimum of 40 percent Acceptable cover standards for the wetland herbaceous species will be at least 80 percent. DRAFT maintenance responsibilities such as trash removal and vandalism repair will be performed on an as- needed basis. CONTIGENCY PLAN If the project fails to meet the standards discussed above, implementation of a contingency plan will be required by Ecology and Jefferson County. The contingency plan will supplement the wetland mitigation plan and will be based off of assessments made during mitigation monitoring events and additional site visits. As problems are recorded, suggestions and possible solutions will be forwarded to Ecology and Jefferson County as a component of the monitoring reports. GeoEngineers will work in conjunction with Ecology and Jefferson County to develop the contingency plan. The plan will anticipate problems and specifically address issues such as the eradication of invasive species, supplemental irrigation as required, replacement plant installation of deceased plants, damaged or missing structures or vandalism. The plan will follow the protocol set forth in this Mitigation Plan and also provide greater detail about specific measures required to help the site meet its goals, objectives and performance standards. If more than 20 percent mortality of plantings occurs within any of the monitoring years, the problem areas will be replanted, preferably in the dormant season and provided with better maintenance to ensure higher plant survival. If, in the judgment of the monitoring biologist, altemative plant species are needed to improve survival, alternative species will be selected. IMPLEMENTATION SCHEDULE Statesman will follow the timeline approved and agreed upon by the regulatory agencies in regards to the development of the MPR and the construction of the mitigation areas.

After reviewing your submitted information and visiting the site we have determined that wetlands "b", "c" and "d" shown on the enclosed map are not wat€rs of the United States. As such, the work that would o@ur within these wetlands marked on the enclosed drawing does not require Department of the Army authorization under Section 404 of the Clean Water Act. This approvod jurisdictiond daermination is valid for a period of 5 years from the date of this letter unless neu' information warrants revisions of the deermination. Other state and local regulations may still apply to these wetlands. For example, the Washington State Department of Ecology (Ecology) regulates isolated wetlands. You should contact Ecology's Office of Regulatory Assistance's One-Stop Service Center at (800) 917-0A43 or ec)pac(ir,ccr . s a.qor. for more information on how to obtain State approval for your project. We are sending a copy of this letter to Ecology and to the Environmental Protection Agency's Aquatic Resources Unit. A cop)'of this letter with enclosures u'ill be sent to the Washington Depanment of Ecolog1,, Office of Regulatory Assistance's One-Stop Service Center and GeoEngineers.

YES - the wetland class is Tidal Fringe e salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) Ifyow wetland cot be classified as a Fresh'nater Tidal Finge use theformsfor Riveiru vrytlm^. If it is a fultvater Tidal Finge it is rated as m Estaairv wetlond. Wetlands that were call eshurine in the first and second editiqrs of the rating qmtem are called Salt Water Tidal Fringe in the Hydrogeomrphic Classificatian. Esurarine wetlands were categmized sryarately in the earlia editiors, and this separatim is being kqt in this revisiur. To maintain cursistency between editianq the terrn'Estuarind' wetland is kept Please nde, however, that the characteristics that define Categry I and II estuarine wetlands have changed(seep. _). 2. The entire wetland unit is flat and precipitation is only source (>90%) of water to it. Groundwater and surface water runoff are NOT unit. YES - The wetland class is Flats If your wetland can ed as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland meet both of the following criteria? I fne vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; E At least 30%area is deeper than 6.6 (2 m)? YES - The wetland class is 4. Does the entire of the following criteria? f] fne wetland is on a slope (slope can be very gradual). E fne water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ! fne water leaves the wetland without being impounded? NOTE: Surface water does nol pond in these types of wetlands except occasionally in very small and shallow or behind hummocks (depressions are usually <3 ft diameter and less than I foot deep). to5 YES - The wetland class is 5. Does the entire all of the following criteria? The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE can contain depressions that are filled with water when the river is not Jlooding.. YES - The wetland class is Riverinego 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if NO-goto7 presplis-hi.Nhan the interior ( YES - T!) wetland class of the wetland. is Depressional 7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches.

I Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. f] Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres) fl Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft. f] OIA-growth forests: (Old growth west of Cascade Crest) Stands of at least 2 tree species, forming a multi-layered canopy with occasional small openings, with at least 20 trees/ha (8 trees/acre) > 8lcm (32 in) dbh or > 200 years ofage. f] Mature forests: Stands with average diameters exceeding 53cm (21 in) dbh; crown cover may be less than 100%; decay, decadence, numbers ofsnags, and quantity oflarge downed material is generally less than that found in old-growth; 80 - 200 years old west ofthe Cascade Crest. f] Prairies: Relatively undisturbed areas (as indicated by dominance ofnative plants) where greases and/or forbs form the natural climax plant community. f] Talus: Homogenous areas of rock rubble ranging in average size 0. l5 - 2.0m (0.5 - 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. I Caves: A naturally occurring cavity, recess, void, or system ofinterconnected passages. I Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is25%. fl Urban Natural Open Spacc: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; and/or the open space is an isolated remnant ofnatural habitat larger than 4 ha (10 acres) and is surrounded by urban development. I Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runofffrom tbe land.

In the open, it forms a round, spreading crown, while in a dense stand it becomes a tall straight tree. It has long clusters of yellow flowers in the spring, and very large, lobbed leaves which turn yellow in the fall. Various birds eat its two-winged "helicopter" fruits, and the leaves provide foliage for deer and elk. Young trees grow rapidly in the spring (Thurston County Conservation District 2005). It grows in dry to moist sites, often with Douglas fir and often on sites disturbed by fire, clearing or logging at low to middle elevations (Pojar and MacKinnon 1994). Douglas Fir (Pseudotsuga menziesii\: This tree grows well in various soil types, especially in sunny areas. It has flat needles that are sharp-pointed but not prickly, and many medium-sized cones that drop to the ground each fall. The ridged Douglas fir bark on older trees is fire-resistant because of its thickness. An uncrowded tree has pyramidal crown with dense foliage. Deer and rodents browse on the seedlings, and small birds and mammals eat the seeds. It needs well-drained soil and full sun but is located everywhere from extremely dry, low elevation sites to moist mountain sites (Thurston County Conservation District 2005 and Pojar and MacKinnon 1994). Pacific Willow (Salix lucida ssp. lasiandra): This tree typically has one or more leaning, crooked trunks and an upright to rounded form. It can grow 20 to 40 feet tall as a deciduous shrub or tree and grows in coastal dune wetland communities along the outer coast and coastal freshwater swamps around Puget Sound (Department of Ecology 1993). The branches are brown and twigs glossy, with yellow, duckbill-shaped buds that are usually hairless and brittle at base. The bark is fissured yellowish-brown on older trees. This plant is found along riverbanks, floodplains, lakeshores and wet meadows. It tolerates full sin to partial shade and prefers moist soils (Pojar and MacKinnon 1994).

It is a deciduous tree, usually single stemmed and forms pure stands or intermixes with Westem Red Cedar and Westem Hemlock. Red alder is intolerant of shade and will grow in nitrogen-deficient soils due to its ability to fix atmospheric nitrogen. This tree provides food for grouse, pine siskin, black-capped chickadee, kinglet and beaver and is a common nest tree for great blue heron (Department of Ecology 1993). It tends to grow in moist woods, sheambanks, floodplains, slide tracks, and recently cleared land and is often found in pure stands and at low elevations (Pojar and MacKinnon 1994). Western Red Cedar (Thuja plicata): This is a sweet-smelling, coniferous evergreen tree that likes moist soil but can also survive in drier habitats. It grows slowly, but can grow to heights of between 60 and 200 feet. As it grows, its crown becomes open and its lower branches droop. Clusters of small brown cones grow at the ends of the branches (Thurston County Conservation District 2005). Instead of needle leaves, it has tiny scales set snugly on the branches and it is resistant to rot and fungus (Pojar and MacKinnion et al. 1994). It provides protective and nesting cover for wildlife and also provides twigs and foliage for browsers. Its bluish-black, berry-like fruit is important to many large and small birds and mammals (Martin et al. 1961). Sxnues Evergreen Huckleberry (Vaccinium ovatum): This plant has glossy, dark green leaves on many erect, hairy branches which start at the base of the plant. It produces purplish-black fruits. New shoots are bronzy red, and mature foliage is often reddish purple (Thurston County Conservation District 2005). It is found in the understory of coniferous forests (especially edges and openings) at low elevations. It also prefers shade and grows in moist to dry sites (Pojar and MacKinnon 1994).

Ir L 't \ DRAFT Pacific Ninebark (Physocarpus capitatus): Pacific ninebark is a deciduous shrub that grows to about 15 feet tall. It typically grows in moist but well-drained soils along streams, in full sun to part shade (Department of Ecology 1993). It also grows in wet, somewhat open spaces (streamside thickets, edges of moist woods, coastal marshes, meadows, margins of lakes and streams) and occasionally on drier, shrubby sites (Pojar and MacKinnon 1994). The twigs and greenery provide browse for girds and wildlife. Salil (Gaultheria shallon): This plant is a robust, evergreen shrub which often forms dense thickets. It has lustrous, dark green leaves, showy pink flower clusters, and purplish-black berries that are eaten by birds, rodents and people. Salal can be damaged by the strawberry root weevil (Thurston County Conservation District 2005). It occurs in the understory of coniferous forests and rocky bluffs and is found in low to medium elevations. It likes partial shade to deep shade and is found in moist to dry sites (Pojar and MacKinnon 1994). Salmonberry (Rubus spectabilis): This shrub can grow 3 to l0 feet high and has shredding, light- or golden-brown bark. It has woody sparsely thorned stems; and zigzag twigs. Flowers are large (about I % inches across), borne singly, and are pink to dark or purplish-red. Large raspberry-like fruits appear in late spring, ripening over a fairly long period to become yellow to red or deep purple (United States Army Corps of Engineers 2005). Salmonberry grows in moist to wet places, often abundant along stream edges, avalanche tracks and in wet logged areas. It prefers full sun to fulI shade (Pojar and MacKinnon 1994).

The leaves are green during the summer but during the fall they turn either golden in the shade or bright red in full sun. It has white flowers that form in clusters at the end of the shoots and winged fruits that turn red or brown. This plant grows in moist to wet places and prefers partial to deep shade which typically occurs under tree canopies (Pojar and MacKinnon 1994). HeRseceous Sword Fern (Polystichum munitum): This evergreen shrub will typically reach 2-ll2 to 2 feet in height and 4 feet in diameter. The leaves are narrow lance-shaped pinnately dark green with fringed edges. Large orange spores appear on the underside of each leaf. The roots are rhizomes (Thurston County Conservation District 2007). Typically found in moist forests at low to middle elevations, it is abundant and widespread throughout the Pacific Northwest (Pojar and Mackinnon 1994). Slough sledge (Carex obnupta): This herbaceous plant grows one to three feet tall and spreads by rhizomes to form monotypic stands. It is limited to western Washington and required wet soils to flourish. The plant can tolerate deep shade or full sun and commonly grows in red alder-dominated swamps in association with skunk cabbage, water parsley and salmonberry (Department of Ecology 1993).

It spreads by rhizomes slowly and eventually spreads to form clusters of individual plants. It grows in partial shade to full shade and prefers wet to moist soils (Department of Ecology 1993). It is commonly found in moist to wet forest, swamps, thickets, openings, slidetracks, streambanks, gullies, meadows and clearings (Pojar and MacKinnon 1994). Small-fruited bulrush (Scirpus microcarpu.y': This herbaceous plant grows between two to four feet tall and is a deciduous perennial herb. It spreads by rhizomes to form monotypic stands in saturated soils and shallow seasonal standing water. It is commonly found along streams and in freshwater marshes (Department of Ecology 1993). Stems usually clustered, from a sturdy rhizome, stout, triangular, leaff, to 1.5 m tall. It grows in full sun and prefers wet to shallow water (Pojar and (MacKinnon 1994).
