The property is listed as Assessor's Parcel #001-184- 006 and is located in the Southeast Quarter of Section 18, Township 30 North, Range 1 West (Figures 1, 2, 3 and 4). The Site is located about 1.5 miles southwest of Port Townsend. The owners of the parcel are Amy M. Hiatt and David Pratt at 234 Sand Road, Port Townsend, Washington. This report has been conducted for the area of the parcel and wetland edges most pertinent to the proposed project. The property owner intends to construct a new home and a detached garage on the property between two wetlands. The Site presently contains a residence, well and septic system. A new septic system and drainfield will be installed. The existing drainfield will be abandoned and the existing residence will be demolished. The new garage will be placed roughly where the existing residence is located The parcel was checked for environmentally sensitive areas by Westech Company (Westech) and was found to contain two depressional wetlands, one also containing characteristics of a slope wetland. This report delineates the wetlands lying on the parcel. (See Site Photographs in Appendix A). The Property owners contracted with Westech to delineate and rate these wetlands and determine the buffer required under the Jefferson County Codes. This Wetland Delineation is intended to assist in determining the optimal location for placing the new septic system. Chapter 2.0 describes the Methodology used to conduct this Wetland Delineation. Chapter 3.0 contains results of the Wetland Delineation. Field investigations of the wetland were conducted by Mr. Charles Tanner and Dr. G. Bradford Shea during February 2014. One wetland was classified as a Category III wetland and the other a Category IV wetland. The former requires a 60 foot buffer for projects of this size, while the latter requires a 40 foot buffer. The Wetland boundaries have been marked in the field. WW1299SRWD. RPT/041414/mas 1 "-I I N ,000'SOo2V N ,000'StIoZV N ,000'SZoZ-� N ,000'SOoZt, V j � AC t �`% --1 � V *Z t v 0 . . N C7 f "O O �.

The JCC requires that wetlands be identified and delineated according to procedures in the 1997 Washington State Department of Ecology's (WDOE) Washington State Wetlands Identification and Delineation Manual (Ecology Publication No. 96-94 or as amended) (JCC 18.22.300). Because the State of Washington now defers to the U.S. Army Corps of Engineers' (Corps) wetland delineation methods, this wetland was delineated according to the Corps' Regional Supplement for the Western Mountains, Valleys and Coast Region (Corps 2010). The Wetland was rated by the methods outlined in the Washington State Department of Ecology's Wetland Rating System for Western Washington (WDOE 2006). The following methods are drawn from the Corps' Supplement for the Western Mountains, Valleys and Coast Region (Corps 2010). The Corps' manual defines wetlands as those "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions." Wetlands are defined by the following three criteria: 1. Vegetation: Prevalent vegetation consisting of macrophytes adapted to areas with wetland hydrologic and soil conditions. 2. Hydric soils: Soils that are histosols, in aquic suborders or that show certain characteristics associated with poor draining, very poor draining or ponding for a long duration during the growing season. 3. Hydrology: Evidence that the area is inundated or saturated to the surface between 5 and 12.5 percent of the growing season in most years. Evidence of at least one wetland indicator from each of these three categories is generally required to identify an area as a wetland. Preliminary data gathering consisted of the examining U.S. Geological Survey (USGS) maps, county parcel, wetlands, and topographic maps, aerial photographs and Natural Resources Conservation Service (NRCS) soil surveys. Because these sources were insufficient to make a determination, additional information on site vegetation, soils and hydrology was unavailable, and the site did not appear to have the complexity to require a comprehensive determination, a Routine Determination with Onsite Inspection was used. WW1299SRWD.RPT/041414/mas 6 Because both wetlands on -Site were less than five acres, the procedure for "Areas Equal to or Less Than 5 Acres in Size" was used. The wetland and its boundaries were initially estimated by noting likely areas of topographic and vegetative distinction between wetlands and uplands. The routine method for delineating wetlands begins with the identification of plant communities, as uplands and wetlands are often occupied by different assemblages of species determined by combinations of environmental influences. These plant communities were identified and evaluated for the presence or absence of hydrophytic vegetation. The wetland indicator status of the dominant species is used to determine the presence of hydrophytic vegetation. Each species has an indicator status defined according to the U.S. Department of Agriculture (USDA) (USDA 2012). A species indicator status refers to the relative frequency at which the species occurs in jurisdictional wetlands. Wetland plant species (OBL, FACW and/or FAC) must constitute greater than 50 percent of the dominant vegetation to meet Department of Ecology (DOE) criterion for hydrophytic vegetation (Corps 2010). Because plant coverage varied significantly across the wetland, small transects could not be utilized to estimate percent coverage. Accordingly, a combination of on -Site visual inspection and aerial maps were used to estimate percent coverage. These estimates were used to conduct a dominance test with 50/20 selection as described in the Corps manual (Corps 2010). Wetland plants were primarily identified in the field, with subsequent collection and keying when necessary. Plants were identified using the following sources: Pojar and MacKinnon 1994 (Updated 2004) Guard 1995 Cooke 1997 Hitchcock and Cronquist 1973 Lyons1997 Taylor 1995 Keying of plants using magnifying lenses and dissecting microscope was used as necessary. Determination of wetland indicator status utilized regional keys published by USDA. This indicator replaced the previous U.S. Fish and Wildlife key in June 2012 (USDA 2012). Areas with plant communities dominated by hydrophytic vegetation were then evaluated for wetland hydrology and hydric soils. Wetland hydrology refers to "all hydrological characteristics of areas that are periodically inundated or have soils saturated to the surface at some time during the growing season." These are areas with evidence that the presence of water has an overriding influence on the characteristics of vegetation and soils due to anaerobic and reducing conditions (Corps 2010). An area has wetland hydrology if it is inundated or saturated to the WW1299SRWD.RPT/041414/mas 7 ..o surface continuously for at least five percent (5%) of the growing season in most years. The level of inundation can range from permanently inundated to irregularly inundated/saturated. The level of inundation/saturation can be impacted by precipitation, topography and soil characteristics. Hydrology is often the least exact of the parameters used to delineate wetland edges because it is the most ephemeral and leaves the least reliable traces in the landscape after water tables or floods have receded. Therefore, indicators of wetland hydrology are sometimes difficult to find in the field. However, it is essential that a wetland area is periodically inundated or has saturated soils for a sufficient duration during the growing season. Based on Corps recommendations, Westech staff noted areas with evident characteristics of wetland hydrology. In general, places with wetland hydrology show evidence that the presence of water has had an overriding influence on characteristics of vegetation and soils due to anaerobic and chemically -reducing conditions. Hydrologic conditions were determined through examination of topographic relief and drainage patterns. Soil moistness was determined by hand and, in the event of standing water, depth to standing water was noted. Field indicators of wetland hydrology include such features as watermarks, historic records, and visual observation of saturated soils or inundation. Evidence of hydric soils was checked along the apparent wetland boundary. These are soils that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper layers. These soils are identified in the field mainly by morphological features such as color patterns, organic matter accumulation, and observation of inundation. Soils were sampled to depths of up to 18-24 inches using a wetland shovel. Soil consistency was determined by feeling for grain size and texture. Soil moisture was determined at that time. In the event of saturated conditions in the hole, depth to standing water was noted. Soil color was determined through comparison of field samples with standard Munsell Color Charts (Munsell 1994). Soil was also examined for presence of redox features, gley or other indicators of anaerobic soil oxidation. If one or more of these indicators was present in the wetlands, the soil was considered hydric. Wetlands were determined based on the Routine On -Site Field Method used by the Corps using a combination of vegetation, soil and hydrology indicators. The boundaries of the wetland were determined by first mapping each plant community area as wetland or non -wetland. The general wetland boundary was determined by the interface of these two mapping units. These boundaries were confirmed and the boundary locations narrowed down by sampling specific transects along wetland boundaries. Various points were sampled for vegetation, soil and hydrology in order to pinpoint the location of wetland boundaries. Appendix B contains data forms for WW1299SRWD.RPT/041414/mas 8 6� i two sample points (one wetland and one upland) from a typical area in the delineated wetland. Wetland boundaries were indicated in the field by the use of pink "Wetland Delineation Boundary" flagging tape tied to the wooden stakes (24" or 48") or to trees as appropriate. All boundaries were staked and/or flagged every 25-30 feet. Buffer widths were determined based the Jefferson County Critical Areas Code and marked in the field with orange and black tape. Soil test pits were indicated by orange/white diagonal flagging and stakes containing the test pit number. Site visits were carried out in February 2014 by Mr. Charles Tanner and Dr. G. Bradford Shea. Exploration of the Property involved noting Site characteristics such as hydrology and soil conditions. A botanical study involving identification of the plant species found growing on the Site was also conducted. The wetland edge was delineated and photographic documentation was acquired (Appendix A). Measurements for mapping purposes were made using a fiberglass tape measure. WW1299SRWD.RPT/041414/mas 9 i 3.0 WETLAND DELINEATION RESULTS 3.1 Existing Conditions The 10.1 acre parcel is located about 1.5 miles southwest of Port Townsend and 1.9 miles northeast of Discovery Bay. The surrounding area includes lowland coniferous and deciduous forests located on a peninsula surrounded by marine waters. The Site itself sits in a large depression bounded by gradually sloping terrain from north to south, moderately sloping terrain to the east and more rapidly rising terrain from to the west. After rising to about 480 feet above msl about one- half mile west of the Site, the landscape grades to sea level at Discovery Bay. The area is less developed to the southwest and more developed to the northeast, with several cleared areas and single rural housing sites located north and east of the property. Several gravel pits are also located approximately one-half mile northeast of the property. A single housing unit is located on the southeast part of the parcel. This home is 1,128 square feet in area according to County Assessor's data. The property is rated Rural Residential 1:10 indicating an allowance of one residence per 10 acres. The Site presently contains a residence, a shop building, a well and septic system. The property owner intends to construct a new residence and a garage on the property between two wetlands. The owners also intend to place a septic line linking to a drainfield. According to an email from the county, utilities lines connecting to a structure are considered low impact uses (Johnson 2014). Westech Company's (Westech) field investigation determined that two wetlands are located on the Site. One wetland is depressional while the other exhibits characteristics of both slope and depressional wetlands. The depressional wetland is located in a deciduous forest on the eastern portion of the parcel while the depressional/slope wetland is located in a cleared field in the central portion of the property. Wetland boundaries were determined by first noting likely areas of topographic and vegetative distinction between wetland and uplands. The Site vegetation was found to transition from upland to wetland in a relatively distinct fashion in the eastern depressional wetland (Wetland A). The wetland (shrub -scrub wetland) contains scattered tree and a shrub layer. Vegetation patterns were less distinct on the centrally -located wetland (Wetland B). Because of the complex patterns, soil characteristics and hydrologic influences were especially important in marking the line separating Wetland A from adjacent upland areas in the field. Evidence of hydric soils was also checked along the apparent wetland boundary. Westech staff noted the presence of a dark layer overlaying a depleted matrix in the boundary areas of the wetland. WW1299SRWD. RPT/041414/mas 10 Westech staff also noted the presence of hydrological indicators. While difficult to find, and often the least exact of the three indicators, Westech staff noted areas with evident characteristics of wetland hydrology, places where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and chemically -reducing conditions. These included standing water in both wetlands. The vegetation, soils, and hydrology of the Site are described in more detail in the following subsections. Results of these three factors at four test pit locations (two in the wetlands, two in the upland areas) are contained in Appendix B. Figure 5 shows the location of the wetland relative to nearby features. Site photographs are shown in Appendix A. Vegetation The Site vegetation in both wetlands consists primarily of native vegetation (Tables 1 and 2). This was also the case for upland areas adjacent to both wetlands. As these tables indicate, vegetation in Wetland A and Wetland B consisted of distinct communities. Wetland A (Table 1) (shrub -scrub wetland) was identified first by the presence of Pacific crabapple (Malus fusca, FACW), Pacific willow (Salix lucida, FACW, scouler's willow (Salix Scouleriana, FAC) and cottonwood (Populus balsamifera, FAC) in the tree layers; and Douglas spirea (Spirea douglasii, FACW), Nootka rose (Rosa Nutkana, FAC) and black twinberry (Lonicera involucrata, FAC) in the shrub layer. The herb layer did not meet Cowardin requirements for inclusion. Upland vegetation transitions rapidly up a short incline to areas dominated by salal (Galutheria shallon, FACU) and sword fern (Polysticum munitum, FACU). Wetland vegetation in Wetland B (Table 2) was dominated by creeping buttercup (Ranunculus repens, FACW) and a variety of grasses. Some slough sedge (Carex obnupta, OBL) and common rush (Juncus effusus, FACW) were also present. Douglas spirea dominated wetland shrubs and no tree layer was present. The upland area was comprised of a mix of creeping buttercup, grasses, with patches of rush. Tables 3 and 4 shows the results of dominance tests conducted following the guidelines of the Corps (Corps 2010). As this table indicates, the dominant species in Wetlands A and B were rated OBL, FACW or FAC. While this was not the case for upland areas adjacent to Wetland A, it was the case for areas adjacent to Wetland B. The vegetation in both wetlands can thus be characterized as hydrophytic for the purposes of delineating the wetlands. WW1299SRWD.

These soils are identified mainly by morphological features such as color patterns, organic matter accumulation, or observation of inundation. A soil may be considered hydric if it is inundated (flooded or ponded) for at least one continuous week during the growing season in most years (Corps 2010). Westech staff looked for field indicators of hydric soil conditions as recommended by the Corps. If one or more of these indicators was present in the wetlands, the soil was considered hydric (Corps 2010). Westech staff first examined existing Natural Resource Conservation Service (NRCS) soil surveys of the Site. The NRCS maps four soils on the Site (NRCS 2014). The scale of the maps do not allow firm conclusions about the specific location of these soils on the property. The four soils mapped by the NRCS on the Site include: Belfast silty clay loam� wet variant (arn This soil is associated with flood plains and alluvium and with 1 to 2 percent slopes. The soil is described as consisting of a silty clay loam from 0 to 9 inches, loam from 9 to 20 inches and stratified gravelly fine sandy loam to clay loam from 20 to 60 inches. This soil is listed as poorly drained, has occasional flooding and no frequency of ponding. It is also listed as having more than 80 inches to the most restrictive layer and 6 to 12 inches depth to the water table. The soil has a high (about 10.3 inches) available water capacity and a moderately high (0.20 to 0.57 inches/hour) capacity of its most limiting layer to transmit water. Belfast silt loam wet variant Bk : This soil is associated with flood plains and alluvium and with 1 to 2 percent slopes. The soil is described as consisting of a silt loam from 0 to 20 inches and stratified gravelly fine sandy loam to clay loam from 20 to 60 inches. This soil is listed as poorly drained, has occasional flooding and no frequency of ponding. It is also listed as having more than 80 inches to the most restrictive layer and 6 to 12 inches depth to the water table. The soil has a high (about 10.3 inches) available water capacity and a moderately high (0.20 to 0.57 inches/hour) capacity of its most limiting layer to transmit water. Ho us gravelly loamy sand 0 to 15 percent slopes HuC : This soil is associated with terraces and glacial outwash and 0 to 15 percent slopes. The soil is described as a gravelly loamy sand from 0 to 60 inches. This soil is listed as somewhat excessively drained and has no frequency of flooding or ponding. It is also listed as having more than 80 inches to the most restrictive layer and 80 inches depth to the water table. The soil has a very low (about 1.6 inches) available water capacity and a high to very WW1299SRWD. RPT/041414/mas 17 high (5.95 to 19.98 inches/hour) capacity of its most limiting layer to transmit water. Clallam gravelly sandy loam, _0_to 15 percent slopes (CmC): This soil is associated with basal till and 0 to 15 percent slopes. This soil is described as a gravelly sandy loam from 0 to 3 inches, a very gravelly sandy loam from 3 to 23 inches, and a gravelly sandy loam from 23 to 60 inches. This soil is listed as well drained and has no frequency of flooding or ponding. It is also listed as having 20 to 40 inches to the most restrictive layer and about 19 to 39 inches depth to the water table. The soil has a very low (about 1.9 inches) available water capacity and a very low to moderately low (0.00 to 0.06 inches/hour) capacity of its most limiting layer to transmit water. Both the Belfast silty clay loam and Belfast silt loam appear on the NRCS list of hydric soils. Neither the Hoypus gravelly loamy sand nor Clallam gravelly sandy loam are listed by the NRCS as hydric soils (NRCS 2014). Because NRCS soil surveys do not necessarily capture small scale variation, Westech staff conducted additional field studies of the soils. Westech staff found that on -Site soils in and adjacent to the on -Site wetland were similar to NRCS soil designations for both Belfast soils. To examine soils in the wetland boundaries, Westech staff dug many soil pits and observed soil characteristics. The location of four soil pits examined in detail by Westech, are shown in Figure 5. These VSH plots are located within representative upland and wetland areas. The location of these plots has been marked in the field using wooden stakes tied with orange and white striped flagging. The soil information taken at these sample points is highlighted in Table 5. As indicated here these soils meet the U.S. Army Corps criterion for hydric soils, in particular, for a dark layer above a reduced matrix. WW1299SRWD.RPT/041414/mas 18 TABLE 5.

Wetland hydrology was the best indicator of the dividing line between wetland and upland. A soil pit in the wetland area indicated a water table in the roots zone (about 10 inches). The upland area showed no indications of wetland hydrology. Both soils were a silt loam. WW1299SRWD.Tab5/041414/mas 19 "•'I As Table 3 indicates, the soils observed in Wetland A have wetland characteristics distinct from the adjacent upland soils. Soils in this wetland met the Corps' criterion for a dark layer above a reduced matrix. These included a silt loam upper layer of about 8-10 inches with a matrix with a value/chroma of 3/1 and a reduced matrix (value/chroma 5/2) with over 5 percent redox features. While having a dark chroma, soils in the upland area had a limiting layer of hardpan about 10 inches below the surface. These soils meet the Corps' criterion for hydric soils (Corps 2010). Soils in both the upland and wetland areas of Wetland B were similar, meeting the Corps' criterion for a dark layer with a reduced matrix. This included an upper layer of about 8-10 inches with a value/chroma of 3/1 (10YR) and a reduced matrix of value/chroma 5/2 (10YR) with over 5 percent redox features. These soils meet the Corps' criterion for hydric soils (Corps 2010). Because soils were similar in wetland and upland areas, hydrology was important to delineating the boundaries of Wetland B. Hydrology Numerous factors (e.g., precipitation, topography, soil permeability, and plant cover) influence the wetness of an area. The water source for these wetland comes from a combination of direct precipitation, runoff from uphill areas and groundwater sources. In Wetland A, observations in the soil pit indicated a water table at between 6 and 10 inches below the surface. Hardpan was found at about 10 inches in the wetland area. In Wetland B, hydrology was a key indicator of the dividing line between wetland and upland. A soil pit in the wetland area indicated a water table in the root zone (about 6 inches). Upland areas showed a water table below 12 inches. These features fit the Corps' criterion for wetland hydrology (Corps 2010). 3.2 Description of Wetlands The wetlands at this Site consist of one depressional wetland and one wetland exhibiting depressional and slope characteristics. The location of the wetlands are shown in Figure 5. The edges of the wetland have been delineated in the field by Westech. Pink "Wetland Delineation Boundary" flags were used to mark the line differentiating wetland areas from upland areas. Wetland A, a shrub -scrub wetland, lies on the eastern portion of the property in a small deciduous forest that itself is bounded to the east by a coniferous forest. The wetland lies entirely in a depression. The tree layer in the wetland consists of Pacific crabapple (Malus fusca, FACW), Pacific willow (Salix lucida, FACW), Scouler's willow (Salix Scouleriana, FAC) and cottonwood (Populus balsamifera, FAC) in the tree layers. The shrub layer consists of Douglas spirea (Spirea doug/asii, FACW), Nootka rose (Rosa Nutkana, FAC) and black twinberry WW1299SRWD.RPT/041414/mas 20 r_-w (Lonicera involucrata, FAC) in the shrub layer. The herb layer did not meet Cowardin requirements for inclusion (Corps 2010). Wetland B lies in the central portion of the parcel. It occurs in a larger depression extending onto the adjacent property to the south. This wetland exhibits depressional and slope characteristics because it declines gradually across the landscape from north to south before being bounded by a slight incline at a road adjacent to its southern border. A culvert beneath the road restricts outflow to the adjacent property. This wetland is dominated by creeping butter cup and mixed grasses in the herb layer and Douglas spirea in the shrub layer. It has no tree layer. In addition to precipitation, this wetland is also fed by a shallow seasonal swale that flows from the north end of the property before dissipating in the wetland. 3.3 Land Uses and Habitat Values The Site is between Port Townsend and Discovery Bay. The surrounding area is characterized by a lowland coniferous forest, cleared lands and small areas of deciduous forests. Wetlands are transitional areas between upland and aquatic environments where water is present long enough to form distinct soils, and where specialized, water - tolerant plants grow. Wetlands serve a variety of functions such as transferring surface water into the ground, thereby recharging groundwater supplies. Wetlands also trap water along with sediments and pollutants providing stormwater detention, mitigating flood impacts and providing wildlife habitat. Wetland buffers are important because they reduce the adverse impacts of adjacent land uses on wetlands. The buffers serve to stabilize soil and prevent erosion, filter suspended solids, nutrients and toxic substances and moderate impacts of stormwater runoff. As such, buffers serve to preserve wetland functions. They also provide important habitat for wildlife living in and around the wetland. The location of the wetlands adjacent to an on -Site septic system indicate that the wetland can play a role in improving water quality in the area. The parcel's contribution to water quality can be expected to be incremental due to a "non -fish - bearing stream area" located about one-half mile or greater to the north, south and southwest of the Site. While Discovery Bay has been designated as critical habitat for ESA -listed salmonids, including Puget Sound Chinook (Oncorhynchus tshawytscha) and Hood Canal Summer Chum (Onchorynchus keta), the Bay is approximately 1.9 miles southwest of the Site (NOAA 2005). Wetland A provides a unique deciduous forest wetland in this area otherwise dominated by coniferous forestlands. This wetland will also provide habitat for amphibians because of the presence of thick -stemmed vegetation that is in standing water during part of the year. Pacific treefrog (Pseudacris regilla) WW1299SRWD.RPT/041414/mas 21 M.*I vocalizations were observed during fieldwork. The mix of tree and shrub in this area will provide habitat for a range of bird species and small mammals. Wetland B provides considerably less habitat for bird and animal species. The wetland lacks a tree layer and consists mainly of a mowed lawn and patches of Douglas spirea. 3.4 Wetland Types and Buffers The buffer sizes to be applied at this Site are governed by the Jefferson County Critical Areas Code. In order to establish buffer sizes, Jefferson County requires that wetlands be rated using the Washington State Department of Ecology's Wetland Rating System for Western Washington (WDOE 2006). In this system, wetland ratings are based on: 1) Water Quality Function (i.e., Does the wetland have the ability to improve water quality?) 2) Hydrologic Function (i.e., Does the wetland decrease flooding and/or erosion?) 3) Habitat Function (i.e., Does the wetland provide habitat for many species?) In Washington, wetland rating categories are based on the rarity of the type of wetland, our ability to replace it, its sensitivity to adjacent human disturbances, and the functions it performs. The objective of the rating system is to divide wetlands into groups that have similar needs for protection. Wetland A was classified as a Category III shrub -scrub depressional wetland with an overall score of 40. This included a water quality score of 16, a hydrologic score of 7 and a habitat score of 17. The low hydrologic scores occurred because structures on adjacent lots sit at an elevation higher than the wetland. The Jefferson County Codes require 60 foot buffers to protect these functions in areas of moderate use projects (such as single family residences and appurtenances such as garages and decks). Wetland B was rated as an emergent depressional wetland because it had characteristics of both a slope and depressional wetland. This wetland was classified as a Category IV wetland with an overall score of 23. This included a water quality score of 6, a hydrologic score of 5 and a habitat score of 12. The low hydrologic score occurred because structures on adjacent lots are at an elevation higher than the wetland. The Jefferson County Codes require 40 foot buffers to protect these functions. WW1299SRWD. RPT/041414/mas 22 b" 1 The buffers on each wetland were marked with orange and black tape (JCC 18.22.330, 18.22.330(2)). One exception exists to these buffers. According to Jefferson County, utilities corridors are considered low impact uses. These uses would require 40 foot buffers for Wetland A and 25 foot buffers for Wetland B. Buffers for moderate uses were marked in the field (Johnson 2014, JCC 18.22.330(1)). As mapped by the owners, the Project appears to be located outside of these wetland buffers. The southwest corner of the Project is located approximately 30.5 feet from the buffer of Wetland B while the northwest corner is 16.5 feet from this wetland. The southeast corner of the wetland is approximately two feet from the buffer of wetland A while the northeast corner is approximately 28.5 feet from the buffer of this wetland. 3.5 Jefferson County Wetland Map This Site has been mapped as containing three wetlands by Jefferson County (Jefferson County 2014). County wetland maps appear to be roughly accurate with both Wetlands A and B located by the County in the approximate location of the wetland delineated in this report. The county also maps a third wetland on the southeastern corner of the property. This wetland appears to be located further to the southwest on the adjacent property. WW1299SRWD. RPT/041414/mas 23 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 Conclusions Two wetlands were identified and delineated on the Site. Figure 5 shows the location and extent of the mapped wetlands. A depressional wetland (Wetland A) has been rated according to state guidelines and classified as a Category III wetland. Jefferson County requires buffer widths of 60 feet for this type of wetland and the proposed intensity of land use for the Site. A depressional/slope wetland (Wetland B) has been rated according to state guidelines and classified as a Category IV wetland. Jefferson County requires buffer widths of 40 feet for this type of wetland and the proposed intensity of land use for the Site. Wetland boundaries and buffers have been marked in the field. 4.2 Recommendations The project on this property is located outside of the wetland buffers delineated at this site. This project is allowed under the Jefferson County Code, provided that the facilities are placed outside the buffer zone. Construction activities in the buffer should be accompanied by Mitigation Measures developed in a Mitigation and Habitat Management Plan or Critical Area Stewardship Plan. WW1299SRWD.

If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. Check List for Wetlands That May Need Additional Protection YES NO in addition to the protection recommended for its category) SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are cate Torized as Category I Natural Heritage Wetlands (see .. 14 of data form). SP3. Does the wetland unit contain individuals of Priority species listed hY the iVDFW for the state? SP4_ Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master r` Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To corn fete the next part af the data sheet you will deed to determine the H dr o eomor hic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer'how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. Seep. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form — western Washington 2 August 2004 version 2 Updated with new WDFW definitions Oct. 2008 W.t 1 I Wetland name or number Classification of Wetland Units in Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. in this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are water levels in the entire unit usually controlled by tides (i.e. except during floods)? l Oio to 2 YES — the wetland class is Tidal Fringe If yes, is the 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) If your wetland can be classified as a Freshwater Tidal Fringe use the forms_ for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and IT estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. g=Qndwater and surface water runoff are NOT sources of water to the unit. NOr go to 3 YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without.any vegetation on the surface) at least 20 acres (8 ha) in: size. _A.t least 30% of the open water area is deeper than .6.6 fl (2 m)? �� go to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4: Des the -entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The 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. The water leaves the wetland without being impounded.? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocla (depressions are usually <3ft diameter and less than I foot deep). NO - go to 5 YES — The wetland class is Slope ' Wetland Rating Form — western Washington 3 August 2004 j version 2 Updated with new WDFW definitions Oct. 2008 6� 1 Wetland name or number Lfi 5. Does the entire wetland unit meet 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: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES — The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This rneans that any outlet, ifpresent, is higher than the ii(erior o the wetland.__ NO — go to 7- YF5 The wetland class is Depressional 7. Is the entire wetland unit 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. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS I.N THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recomtnended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. )YGM Classes within the wetland unit heirs rated HGM Class to Use in Rating Slope + Riverine Riverine Slope + Depressional t Slope + Lake -fringe Lake-frin e Depressional + Riverine along stream within boundary Depressional Depressional + Lake-fhn e Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.
