Box 2876 Port Angeles, Washington 98362 M J A Category IV wetland is required to be given a 40 foot buffer with a moderate intensity project within Jefferson County. Since the wetland is also located off-site to the north and south, it likely does not qualify for any buffer exemption as per the Jefferson County Code, Figure 6 shows Wetland A and its on-site buffer zone. 3.6 Jefferson County Wetland Map Jefferson County does not have the on-site wetland mapped on its Critical Areas website. This is likely due to its small size and forested nature with few distinctive features. Field investigations found the Wetland to cover approximately 3,000 square feet of the property with extensions to the north and south (Figure 6).

The owner's current address is 1126 SW 168t1' Street, Normandy Park, Washington 08166-3439. The Project Site is located in Section 18 of Township 26 North, Ranee 1 West, Willamette Meridian, within Jefferson County, Washington. The Project Site is listed as parcel number 601-18-1007. The Site is approximately 1. 12 acres of residential land (roughly 541 feet x 90 feet) that is zoned as R- 1:5 (Rural Residential). It lies along the shoreline of Hood Canal and is in a Conservancy Shoreline Zone, County Assessor's parcel maps and Google Earth aerial maps were used to determine locations and features of the Project Site (Figures 1--4). Field investigation of the wetlands was conducted by Dr. G. Bradford Shea with Mr. Trevor Shea during August and September 2018. The Project Site is presently undeveloped. There is a potable water well installed in the southwest corner of the property. The applicants have submitted an application for a septic system with Jefferson County Environmental Health Department for a single-family residence. Upon approval of that septic permit and this Wetland Delineation Report, the applicants intend to apply for a building permit for a single-family residence. The surrounding area consists of undeveloped lots and several lots with single family residences. There is a single-family residence on the adjacent lot to the north of the Site (Figure 4) and several residences are in the area (along the shoreline to the northeast and a non -adjacent residence to the south). The property has been mapped as containing one wetland located on the west end (Wetland A) of the Site. Mr. Lui Wong contracted with Westech Company (Westech) to delineate the wetland that lies on the Project Site. The Project Site was found to contain a Category IV Forested Slope Wetland (Wetland A) covering a portion of the western edge of the Site. The proposed residence construction is classified as a moderate intensity land use for parcels over 1.0 acres in size under the Jefferson County Critical Areas Code (JCCAC Chapter 18.22.290). Chapter 3.0 of this report contains results of the delineation.

Wetland Rating was accomplished according to the Guidelines of the Jefferson County Critical Areas Code (Jefferson County 2018), and the Washington State Wetlands Rating System (Western Washington) (DOE 2014). Methods for delineation were essentially those recommended by the U.S. Army Corps of Engineers (USACE) for Routine On -Site Field Method of delineation of wetlands as included in the USACE Manual and Regional Supplement (USACE 1987/1989, 2010). Guidelines and requirements of the Jefferson County Critical Areas Code were used as applicable. Wetland plants were primarily identified in the field, with subsequent collection and keying when necessary. Plants were identified using the following sources: Hansen's Northwest Plants Database 2018 USDA NRCS Plants Database 2018 Pojar and Mackinnon 2004 Cooke 1997 Lyons 1997 Taylor 1995 Guard 1995 Hitchcock and Cronquist 1973 Keying of plants using magnifying lenses and dissecting microscope was used as necessary. Determination of wetland indicator status utilized regional keys published by U.S. Fish and Wildlife Service (USFWS) and updated by the United States Department of Agriculture (USDA) (USFWS 1088, USDA 2018). Herbaceous plants were found to be well into the growing season and in good condition within the wetlands. The wetland area was dominated by Red Alder in the tree layer, black huckleberry, snowberry and salmonberry in the shrub layer and reed canary grass and slough sedge in the herb layer. Field investigations were conducted at the end of the dry season (August 2018). Soils were determined through field examination. Soils were dug or augured to depths of up to 18-24 inches using a wetland shovel and standard augur. 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 2009). Soil was also examined for presence of redoximorphic features including mottles (oxidation coloration), gley and other indicators of anaerobic soil oxidation. WW1578-OldPointWhitneyRdWD.RPT/101618/mas 6 Hydrologic conditions were determined through examination of topographic relief and drainage patterns. Soil moistness was determined by hand as indicated above and in the event of standing water; depth to standing water was noted. Initial field surveys were carried out by Dr. Bradford Shea during August 2018 with more detailed follow-up investigations by Mr. Trevor Shea during September 2018. These surveys included identification of plants, wetland habitats, soils and hydrology. Wetlands were determined based on the Routine On -Site Field Method used by Washington Department of Ecology and the U.S. Army Corps of Engineers. Wetlands were determined by a combination of vegetation, soil and hydrology indicators. Specific transect and quadrat points were sampled along apparent wetland edges. Various points were sampled for vegetation, soil and hydrology in order to determine wetland boundaries. Appendix A contains representative site photographs. Appendix B contains data forms for two sample points (one wetland and one upland) from two typical areas of the delineated wetlands. Appendix C contains the Rating Forms and attached maps. Wetlands were staked in the field by 24 and 48 inch wooden stakes, or flagged on trees or shrubs as appropriate. Wetland boundaries were indicated by use of "Wetland Delineation Boundary" flagging tape tied to the wooden stakes or trees. All boundaries were staked and/or flagged every 25-30 feet. Buffer zones near the proposed project area were mapped using GPS measurements which were then plotted on aerial photographs using Google Earth Pro. WW1 578-OIdPolntWhitneyRdWD. R PT/101618/mas 3.0 WETLAND DELINEATION RESULTS 3.1 Existing Conditions The Site consists of an undeveloped Site with an existing well and a driveway. It is proposed for development with a single-family residence and septic system. The Site is located south of Old Point Whitney Road in an unincorporated area of Jefferson County near Brinnon, Washington. The Site lies at an elevation extending from sea level to 105 feet above mean sea level (msl). The Site lies adjacent to Dabob Bay, an embayment off of Hood Canal, The Site is surrounded by a mixture of single family residences and undeveloped lots (Figures 3 & 4). Jefferson County maps do not show the on-site wetland. A Wetland Determination study by Westech Company during 2014 led to the discovery of the on-site wetland. This Wetland Delineation constitutes an update of the information from that study and compliance with Jefferson County's requirements for a full Wetland Delineation Report. Westech's field investigation found the wetland to be a Category IV forested slope wetland that encompasses approximately 3000 square feet of the property (with another 100 square feet extending offsite to the north). This is a forested wetland dominated by Red alder (Alnus rubra) with a mixed shrub and herbaceous understory. Vegetation The on-site wetland (Wetland A) lies within a forested area and is made up of mixed forest, shrub and emergent vegetation. Vegetation within Wetland A is dominated by Red Alder (Alnus rubra) in the tree layer, Alaska blueberry (Vaccirnium alaskense) and salmonberry (Rubus spectabilis) in the shrub layer and Reed Canary Grass (Phalaris arundinaceae) and slough sedge (Camx obnupta) in the herb layer. The dominant trees in the upland area are Big -leaved maple (Acer macrophyllum), Douglas fir (Pseudotsuga roen,ziesir), and western red -cedar ( Thuja plicata). There is also a scattering of Red alder (Alms rubra) and western hemlock (Tsuga heterophylla) in the tree layer. The dominant upland shrubs include sword fern (Polystichum munitum), bracken fern (Pteridium aquilinum), oceanspray (Holodiscus discolor ), salal (Gaultheria shallop) and trailing blackberry (Rubus ursinus). There was no significant herbaceous layer found to be present in the upland areas, which were colonized by shrubs in the forest understory. A detailed list of plants found at the Site is shown in Table 1. WW1 678-OldPointWhitneyRdWD.RPT/101618/mas 8 TABLE 1.

WWI 578-OldPointWhitneyRdWD.Tab1/101618/mas 9 Soils "Hydric soils" is a name for soils commonly found in wetlands. 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 examined existing NRCS soil surveys of the Site. The NRCS maps three dominant soils on the Site (NRCS 2018) which are shown in Figure 5. The two soils mapped by the NRCS on the Site include: Coastal Beaches Co are soils associated with tidal influence, storm waves and shorelines. These soils are usually very well drained (sand, gravel and cobble) and have a depth to water table of 0-11 inches. They have a high frequency of flooding. Normal consistency is sands and gravels to a depth of over 60 inches. Hoodsportrc ravelly loam, 0 to 15 percent slopes (HpQ is a moderately well - drained soil associated with terraces with basal till as the parent material. This soil has a very low water storage (about 2.1 inches) and a very low ability to transmit water (0.00 to 0.06 in/hr) in its most limiting layer. It has a depth to water table between 19 to 36 inches. This soil has no frequency of flooding or ponding and is not classified as a hydric soil (NRCS 2018). Because NRCS soil surveys do not necessarily capture small scale variation, Westech staff conducted additional field studies of the soils. To examine soils in the wetland boundary, Westech staff dug soil pits and observed soil characteristics. The location of these plots has been marked in the field using wooden stakes tied with blue and white striped flagging. The soil information taken at these sample points is highlighted in Table 2. Data forms are included in Appendix B. Field investigations found that the soils conformed roughly to the NRCS characterization, consisting of silty and gravelly loam at the various upland test pits that were dug. Wetland soils were found to be a loamy silt (possibly Bellingham silt loam or related soil). The wetland soil pit showed soils with a value/chroma of 2/1 (10YR) from 0-12 inches with oxidized root channels and no observable redox features. The wetland soils were moist but not saturated during this relatively dry early autumn period (following some light rain events). These soils meet the U.S. Army Corps criterion for hydric soils described as characterized by oxidized root channels (C3), Hostosol (A1) and depleted dark surface (F7). The soil pit taken in the upland area had a chroma/value of 3/2 (10YR) from 0-12 inches. These soils did not meet Army Corps hydric soils criterion.

The water source for Wetland A comes from direct precipitation, runoff from uphill areas surrounding the wetland and groundwater sources. Field investigations were taken during the end of the dry season (August - September) which included a few light rainfall events following an extended period of warm dry weather. This wetland is also relatively flat with very low slope adjacent to forested upland areas. These factors led to no evidence of hydrologic indicators including oxidized root channels during Westech's field investigations. Hydrology is likely more evident during the height of the wet season and into the early spring. Adjacent upland soils showed no evidence of saturation in the root zone. 3.2 Description of Wetlands Westech's field investigations determined that one Category IV forested slope wetland is located on the property. That wetland is routed through a culvert under the existing driveway and meets another small slope wetland off-site to the south. From there, the joined wetlands appear to form a small channel which flows southeast to Dabob Bay and the Hood Canal shoreline. 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 well-defined line. Evidence of hydric soils was checked along the apparent wetland boundary. Westech staff noted the presence of soils marked by dark coloration and other wetland features within the boundary areas of Wetland (A). Westech staff were able to find some evidence of the presence of hydrological indicators (oxidized root channels, water saturated leaves etc.), however, soils were not saturated during the field investigations. Field investigations were conducted following the end of the dry season in an abnormally dry, warm summer. Hydrologic indicators are difficult to find, and often the least exact of the three indicators. This wetland is located within a forested slope. The wetland may originate from a seasonal spring on the property to the north. Hydrological indicators are likely only evident during the wet season (winter and early spring). Two soil test pits were mapped and buffers were identified using GPS measuring software. Those points are labeled as VSH-1 (Wetland) and VSH-2(upland) and are shown in Figure 6 (see also Appendix B). Figure 6 also shows the delineated boundary of the wetland and the required standard buffer zone. WWI 578-OldPointWhitneyRdWD.RPT/101618/mas 14 3.3 Land Uses and Habitat Values 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 wafter into the ground, thereby recharging groundwater supplies. Wetlands trap water along with sediments and pollutants providing storm -water detention and filtration; mitigate flood impacts; and provide 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 storm -water runoff. As such, buffers serve to preserve wetland functions. They also provide important habitat for wildlife living in and around the wetland. The property is currently zoned R1:5 and is surrounded by a mixture of undeveloped lots and single-family residences. The proposed project is construction of a single family residence and septic system (Figure 6). This type of project is considered as a moderate intensity land use. 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 f=unction (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 rated as a Category IV forested slope wetland with an overall score of 13. This wetland had a Water Quality score of 4, Hydrologic score of 3 and a Habitat score of 6. WWI 578-OIdPolntWhitneyRdWD.RPT/101618/mas 15 TABLE 2.

The wetland was classified as a Category IV wetland, requiring 40 -foot buffers under the Jefferson Critical Areas Code (Chapter 18.22.290) for moderate -intensity developments. This wetland buffer is shown on Figure 6 and is outside of the proposed project area for the proposed home and septic system. 4.2 Recommendations Figure 6 shows locations of the mapped wetland . The wetland boundary has been staked on the Site. The required 40 -foot buffer zone adjacent to the wetland is also shown on Figure 6. Any construction activities on the Site should be conducted outside the buffer zone. A construction fence (silt fence or equivalent erosion control measure) should be placed between the construction area and the buffer zone prior to any grading for the project. Placement of any construction fencing and silt fences should be based on locations of critical areas (wetlands and the associated buffer zones) as delineated and described in this report and as staked by Westech Company in the field. Grading activities should not take place after September 30 or before May 1 without all possible erosion control measures in place.
