Figure 1 depicts the limits of this follow-up investigation. The results are to be used for planning purposes of the proposed development known as the Olympic Terrace II - Phase II area which is a portion of the overall Port Ludlow - Olympic Terrace property. This report summarizes the updated wetland and stream boundaries including findings of recently established wetlands, streams, and habitats nearest the Olympic Terrace II - Phase II project area. Raedeke Associates, Inc. performed extensive baseline investigations for wetlands and streams within the Olympic Terrace Plat property from June through July of 2000 that are the basis of this investigation. During the current field investigations, we identified seven wetlands and two streams. Since wetlands are dynamic areas with boundaries that often change, five wetland boundaries identified in the previous baseline investigations were re-delineated as part of this work. Only the boundaries nearest the proposed development associated with the Olympic Terrace II – Phase II project area were flagged, and two additional wetland areas were identified during this investigation. For planning purposes, this report includes detailed summaries of our field investigations performed to identify and delineate wetlands as required by State law and in general accordance with Jefferson County Code Title 18 Unified Development Code Chapter 18.22 Critical Areas wetland analysis and reporting requirements. 1 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 1.0 INTRODUCTION 1.1 STATEMENT OF PURPOSE This report documents the results of our March 2017 investigation of the Olympic Terrace II - Phase II property area in Jefferson County, Washington (Figure 1). Raedeke Associates, Inc. conducted extensive investigations of wetlands and streams on the overall Olympic Terrace property these are documented in our wetland assessment report prepared September 28, 2000 (Raedeke Associates, Inc. 2000), The purpose of our investigation was to update and document the current extent and condition of wetlands, streams, and critical habitat areas within or in the vicinity of the current project area. To date, the delineations and ratings for the wetlands within the site have not been confirmed by Jefferson County staff. However, this report was prepared in general accordance with Jefferson County Code Title 18 Unified Development Code Chapter 18.22 Critical Areas Article VIII Special Reports 18.22.450 wetland analysis reporting requirements for planning purposes and may be used to verify the delineations, wetland ratings, and buffers for the site. 1.2 STUDY AREA The site study area encompasses the southeastern portion, totaling approximately 19.2-acres, of the of the 125-acre Olympic Terrace property investigated during our baseline investigations. It is located in a portion of the southern half of Section 21, Township 28 North, Range 1 East, W.M., in unincorporated Jefferson County, Washington. Specifically, the site study area is located directly south and west of the Woodridge II plat, Olympic Terrace I, and consists of Jefferson County Parcel identification numbers 978802504 (8.1 acres), 978802503 (5.6 acres), and 978802502 (5.8 acres). The approximate 19.2-acre study area boundary, referenced herein as the site, is formed by Olympic Terrace I and Mount Wilder road to the north, and Mount Constance Way road and residential homes to the east. The southern site boundary is formed by the southern extent of Section 21, which was evident as an old logging road and an abrupt harvest boundary within the forest. The western extent of the site is formed by the unimproved access road that parallels the eastern boundary of the Port Ludlow golf course. The 125-acre Olympic Terrace property that was the subject of our baseline investigations extends further north, west, east, and southwest of the current site. Property boundaries, wetland flagging, and topography were surveyed and provided by ESM Consulting Engineers, LLC. Drawings received by our office on March 27, 2017 depict the wetland and stream delineation services that are the subject of this report. 2 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 2.0 METHODS 2.1 WETLAND DELINEATION The COE wetland definition was used to determine if any portions of the project area could be classified as wetland. A wetland is defined as an area “inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances does support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (Federal Register 1986:41251). We based our investigation upon the guidelines of the U. S. Army Corps of Engineers (COE) Wetlands Delineation Manual (Environmental Laboratory 1987) and subsequent amendments and clarifications provided by the COE (1991a, 1991b, 1992, 1994), as updated for this area by the regional supplement to the COE wetland delineation manual for the Western Mountains, Valleys, and Coast Region (COE 2010). The COE wetlands manual is required by state law (WAC 173-22-035, as revised) for all local jurisdictions, including Jefferson County. Hydrophytic vegetation is defined as “macrophytic plant life growing in water, soil or substrate that is at least periodically deficient in oxygen as a result of excessive water content” (Environmental Laboratory 1987). The U.S. Army Corps of Engineers National Wetland Plant List wetland indicator status (WIS) ratings were used to make this determination (Lichvar, et al. 2016). The WIS ratings “reflect the range of estimated probabilities (expressed as a frequency of occurrence) of a species occurring in wetland versus non-wetland across the entire distribution of the species” (Reed 1988:8). Plants are rated, from highest to lowest probability of occurrence in wetlands, as obligate (OBL), facultative wetland (FACW), facultative (FAC), facultative upland (FACU), and upland (UPL), respectively. In general, hydrophytic vegetation is present when the majority of the dominant species are rated OBL, FACW, and FAC. A hydric soil is defined as “a soil that is formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part” (Federal Register 1995: 35681). The morphological characteristics of the soils in the study area were examined to determine whether any could be classified as hydric. According to the 1987 methodology, wetland hydrology could be present if the soils were saturated (sufficient to produce anaerobic conditions) within the majority of the rooting zone (usually the upper 12 inches) for at least 5% of the growing season, which in this area is usually at least 2 weeks (COE 1991a). It should be noted, however, that areas having saturation to the surface between 5% and 12% of the growing season may or may not be wetland (COE 1991b). Depending on soil type and drainage characteristics, saturation to the surface would occur if water tables were shallower than about 12 inches 3 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 below the soil surface during this time period. Positive indicators of wetland hydrology include direct observation of inundation or soil saturation, as well as indirect evidence such as drift lines, watermarks, surface encrustations, and drainage patterns (Environmental Laboratory 1987). Hydrology was further investigated by noting drainage patterns and surface water connections between wetlands and streams within and adjacent to the project area. 2.2 ORDINARY HIGH WATER MARK DELINEATION We based our delineation of the ordinary high water mark (OHWM) for streams within the Phase II area on definitions provided under the Washington State Shorelines Management Act of 1971. The Washington State definition for the OHWM is as follows: Ordinary high water line" or "OHWL" means the mark on the shores of all waters that will be found by examining the bed and banks and ascertaining where the presence and action of waters are so common and usual and so long continued in ordinary years, as to mark upon the soil or vegetation a character distinct from that of the abutting upland, provided that in any area where the ordinary high water line cannot be found, the ordinary high water line adjoining saltwater shall be the line of mean higher high water, and the ordinary high water line adjoining freshwater shall be the elevation of the mean annual flood.”…(RCW 90.58.030(2)(b) and WAC173-22-030(5); WDOE 1994). As outlined in the Washington Department of Ecology (WDOE 1994) Shoreline Administrators Manual, the general guidelines for determining the OHWM include: (1) a clear vegetation mark; (2) wetland/upland edge; (3) elevation; (4) a combination of changes in vegetation, elevation, and landward limit of drift deposition; (5) soil surface changes from algae or sediment deposition to areas where soils show no sign of depositional processes; and/or (6) soil profile changes from wetter conditions (low chroma, high soil organic matter, and lack of mottling) to drier conditions (higher chroma, less organic matter, or brighter mottles). 2.3 BACKGROUND REVIEW In preparation for our site investigations, we collected maps and information from the U.S. Fish and Wildlife (USFWS 2016) National Wetlands Inventory (NWI), the U.S.D.A. Natural Resource Conservation Service (NRCS 2017) Soil Survey, Washington Department of Natural Resources (2017) Forest Practices Base Maps, Washington Department of Fish and Wildlife (2017) Priority Habitats and Species (PHS) on-line mapper, and the Jefferson County (2011) Public GIS maps. We examined current and historical aerial photographs (Google Earth 2016) and United States Geological Survey 7.5-Minute Topographic maps (USGS 2017) to assist in the definition of existing plant communities, drainage patterns, and land use. Finally, we also reviewed our baseline 4 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 investigations that we completed in June and July of 2000 (Raedeke Associates, Inc. 2000) in the vicinity of the site. The results of our background review identified four wetland areas within the vicinity of our site per the results of our baseline investigations, two to three streams per NWI maps, two wetland areas per Jefferson County wetland inventory maps, primarily non-hydric soils per NRCS soil survey information, cutthroat trout PHS listed fish species, and large forested areas within topography of peaks, terraces, and valleys per Google Earth aerial imagery and United States Geologic Survey 7.5-Minute topographic maps. 2.4 FIELD SAMPLING PROCEDURES AND DATA ANALYSIS Raedeke Associates, Inc. staff visited the Olympic Terrace project area on March 1, 2017. We examined depressions, topographically low areas, and the base of steep slopes where wetlands may occur as identified on topographic maps and aerial photograph interpretation. In addition, we walked through the study area systematically along transects to search the study area for the presence of areas that could have hydrophytic vegetation, hydric soil, and positive indicators of wetland hydrology. Vegetation, soils, and hydrology were examined in representative portions of the investigated area according to the procedures described in the COE Wetlands Delineation Manual (Environmental Laboratory 1987). Areas investigated were examined per the 1987 Manual as updated by the Regional Supplement (COE 2010). Plant communities were inventoried, classified, and described during our field investigation. We estimated the percent coverage of each species. Plant identifications were made according to standard taxonomic procedures described in Hitchcock and Cronquist (1976), with nomenclature as updated by the U.S. Army Corps of Engineers National Wetland Plant List (Lichvar et. al. 2016). Wetland classification follows the USFWS wetland classification system (Cowardin et al. 1992). We determined the presence of a hydrophytic vegetation community using the procedure described in the 1987 Manual (Environmental Laboratory 1987), U.S. Army Corps of Engineers Special Notice (1991a, (1991b, 1992, 1994), as updated by the Regional Supplement (COE 2010), which requires the use of the dominance test, unless positive indicators of hydric soils and wetland hydrology are also present, in which case the prevalence index or the use of other indicators of a hydrophytic vegetation community, as described in the Regional Supplement (COE 2010), may also be required. Wetlands delineated prior to and after the COE 2010 regional supplement were delineated in general accordance with the applicable delineation requirements at the time of the delineation. We excavated pits to at least 18 inches below the soil surface, where possible, in order to describe the soil and hydrologic conditions throughout the study area. We sampled soil at locations that corresponded with vegetation sampling areas and potential wetland areas. Soil colors were determined using the Munsell Soil Color Chart (Munsell Color 5 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 2009). We used the indicators described in the Regional Supplement (COE 2010) to determine the presence of hydric soils and wetland hydrology for wetland. During these most recent investigations in 2017, the four wetland areas delineated before the COE 2010 supplement were examined per the COE 2010 requirements to determine if previously delineated areas still met the characteristics of a wetland. 6 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 3.0 EXISTING CONDITIONS 3.1 GENERAL PROPERTY DESCRIPTION The project site is located south of Paradise Bay Road within the Port Ludlow community in the northeastern part of the Olympic Pennisula on the northern tip of the Kitsap Peninsula (Figure 1). The property ranges from about 270 to 390 feet in elevation. The western half of the site generally drains to the southwest and westerly direction while the eastern half generally drains to the north. Vegetation on the site is a mosaic of second or third generation forests following timber harvest and replanting. The Phase I area of the Olympic Terrace property is currently under development. The Phase II portions of the site remain undeveloped. 3.2 WETLAND DESCRIPTIONS Raedeke Associates, Inc. identified seven wetlands totaling approximately 1.6 acres and two streams within the study area (Figure 2). These include a riverine wetland (Wetland A) associated with an unnamed stream (Stream 1) located on the western half of the site and forested wetland depressions (Wetlands C, D, E, F, Y, and Z) and a stream (Stream 6). Table 1 lists all seven wetlands within the site area and provides their locations. Table 2 provides a summary of each wetland’s approximate size, Cowardin et al. (1992) vegetation class, and hydrogeomorphic class. Table 3 provides a summary of updated wetland ratings, per the current WDOE rating system (Hruby 2014), and the probable buffer width per Jefferson County (2016) code for each wetland. As part of our most recent site investigations, we revisited 5 of the 13 previously-delineated wetlands in order to verify the accuracy of their boundaries. Where necessary, we adjusted the boundaries to reflect current site conditions. We understand that all proposed development activities are located on the interior portions of the project parcels. Therefore, for this study, we updated only the wetland boundaries nearest the proposed project development. Wetlands or work beyond the proposed site development activities may not be relied on by this report and will require additional delineation services if work is to occur in these locations. In addition, we delineated two wetlands within the site project area that were not identified as part of our previous baseline investigations. Positive indicators for each of the three wetland parameters were present at the time of our 2017 investigations for each of the previously and newly delineated wetlands. Therefore, the delineated areas each met the necessary criteria for designation as wetlands according to the guidelines of the COE (Environmental Laboratory 1987) and Regional Supplement (COE 2010). 7 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 The majority of wetlands within the site meet criteria to be regulated as Category III and IV wetlands providing a moderate to high level of habitat function. With few exceptions, all wetlands and streams at the site would be provided buffers that range from 50 to 150 feet and described in more detail later in this report. Wetlands that provide moderate to high habitat functions would be provided the widest buffers. 3.2.1 Site Wetlands (Olympic Terrace II – Phase II) Wetland A and Stream 1 Based on our previous baseline investigation, Wetland A totals 16,105 square feet (0.37 acres) in area and lies in a narrow, steep-sided ravine located in the southwestern portion of the site. Stream 1 flows into Wetland A and was flagged for ordinary high water as part of this project. Flow from Wetland A occurs along the narrow, steeply-sided bottom of a forested ravine that continues off-site to the south and forms a small stream that ultimately flows into another wetland area just south of the extreme southwestern corner of the site nearest Parcel Number 978820504. Vegetation Wetland A is dominated by a palustrine, scrub-shrub, broad-leaved deciduous (PSS1) vegetation class. Although the wetland is influenced by a canopy of red alder (Alnus rubra), western arborvitae (Thuja plicata), and western hemlock (Tsuga heterophylla) trees, the trees are all rooted upslope and outside of the wetland boundary. The wetland itself is generally dominated by salmonberry (Rubus spectabilis), with portions dominated by overhanging Himalayan blackberry (Rubus armeniancus) and western arborvitae. Skunk cabbage (Lysichiton americanum), slough sedge (Carex obnupta), pig-a-back plant (Tolmia menzesii), fringe cup (Tellima grandiflora), lady-fern (Athyrium felix-feminina), horsetail (Equistetum arvense), and deer fern (Blechnum spicant) are also common components of the herbaceous understory community. Numerous downed logs criss-cross the incised channel and provide substrate for sword fern (Polystichum munitum), red elderberry (Sambucus racemosa), salal (Gaultheria shallon), and red huckleberry (Vaccinium parvifolis). In addition to the Himalayan blackberry, black raspberry (Rubus leucodermis), Pacific blackberry (Rubus ursinus), and evergreen blackberry (Rubus laciniatus) also overhang portions of the northern end of the wetland. All portions of the wetland are dominated by hydrophytic vegetation. Soils and Hydrology Soils within Wetland A consist of a very dark gray (10YR 3/1) silty clay loam ‘A’ horizon, underlain by a very dark grayish brown (10YR 3/2) muck ‘B’ horizon over a grayish brown (10YR 5/2) to yellowish brown (10YR 5/6) sandy loam (Sample Plot A-2, Appendix A). This soil profile generally occurred on the headwaters of a seep at the top of the ravine, approximately 20 feet upslope of the stream bottom. Low chroma and muck soils are indicative of hydric soil conditions. Near the southeastern side of Wetland 8 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 A, a small hillside seep contributes hydrology to this riverine wetland system. At the top of this seep muck soils were encountered along with hydrophytic vegetation. All portions of the wetland had positive primary indicators of wetland hydrology and were saturated within the majority of the root zone. At the time of our site visit, Wetland A was characterized by a stream channel approximately ranging from 3-10 feet wide with 8 inches of water flowing south through the wetland. However, the volume of flow was relatively small and it is likely that the primary contributor to wetland hydrology is interflow and a seasonally perched water table. The adjacent soil profiles of the ravine sidewalls were saturated at approximately 5 inches deep with a water table evident at 15 inches deep according to our previous baseline investigation (Raedeke Associates, Inc. 2000). Classification and Determination Based on our observations, Wetland A meets the necessary criteria for designation as a wetland according to the guidelines of the COE delineation manual (Environmental Laboratory 1987) and the Regional Supplement (COE 2010). Wetland A is classified as a palustrine, scrub-shrub, broad-leaved deciduous (PSS1) wetland. Based on the 2014 WDOE Wetlands Rating Form for Western Washington (Hruby 2014), Wetland A would likely be rated as a Category III wetland (Wetland A, Appendix B). Category III wetlands typically require a 150-foot buffer, depending on the intensity of proposed adjacent land use, according to the Jefferson County (2016) Code. Stream 1, according to Jefferson County GIS mapping information, is mapped as a non-fish habitat stream with a 75-foot stream buffer requirement per Jefferson County (2016) Code. Based on observations during this investigation and previous investigations, the stream appears to flow perennially. Adjacent Uplands The uplands surrounding Wetland A consist of young planted Douglas-fir (Pseudotsuga menziesii) and western hemlock that were part of a restoration effort following clear- cutting over 15 years ago. These areas are currently characterized by an upland shrub community and were differentiated from the wetland mainly by the dominance of non-hydrophytic plant species such as western hemlock, red huckleberry, deer fern, sword fern, Pacific blackberry, Himalayan blackberry, and bracken-fern (Pteridium aquilinum). The surrounding uplands are generally characterized by a very dark grayish brown (10YR 3/2) loam surface horizon, over a yellowish brown (10YR 5/4) sandy loam subsurface, generally without mottles within 12 inches of the surface (Sample Plot A-1, Appendix A). At the time of our site investigations, there was no evidence of saturation or free water within the upper 14 to 18 inches of the soil profile. 9 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 Wetland C Wetland C is located in the southeastern corner of the property, west of a wetland area delineated during our baseline investigation denoted as Wetland B and south of Mount Wilder Way Road. According to our previous baseline investigation, Wetland C totals 15,649 square feet (0.36 acres) in area and is an isolated depression oriented generally north to south. Vegetation Wetland C is characterized by palustrine, emergent persistent (PEM1) and palustrine scrub-shrub, broad-leaved deciduous (PSS1) vegetation classes. The emergent class encompasses the majority of the northern portion of the wetland and is dominated by slough sedge with scattered red alder, Sitka willow (Salix sitchensis), and Pacific willow (Salix lucida) trees. The wetland is fringed by salmonberry and western red cedar. Patches of Pacific blackberry and salal growing on elevated hummocks are interspersed within the wetland. The southern portion of the wetland is characterized by a scrub-shrub community dominated by salmonberry with a fringe of western hemlock and western red cedar trees and an understory of water parsley (Oenanthe sarmentosa) and slough sedge. Tall buttercup (Ranunculus acris), smooth stem sedge (Carex laeviculmis), violet (Viola spp), and tall mannagrass (Glyceria elata) are also common components of the understory in the southern portion of the wetland. Wetland C is thus dominated by hydrophytic vegetation. Soils and Hydrology Soils within the southern portion of the wetland consist of a very dark grayish brown (10YR 3/2) depleted matrix at least 8 inches thick with yellowish brown (10YR 5/4) redoxomorphic features associated with wetland soils (Sample Plot C-2, Appendix A). Low chroma soils with mottles are indicative of hydric soil conditions. At the time of our site investigation, the majority of the wetland was inundated approximately 6-8 inches. Thus, all portions of the wetland had positive primary indicators of wetland hydrology. Wetland C likely receives hydrology from groundwater seepage and a seasonally perched water table. Classification and Determination Based on our observations, Wetland C meets the necessary criteria for designation as a wetland according to the guidelines of the COE delineation manual (Environmental Laboratory 1987) and the Regional Supplement (COE 2010). This wetland is classified as a palustrine, emergent, persistent (PEM1) and scrub-shrub, broad-leaved deciduous (PSS1) wetland. Based on the 2014 WDOE Wetlands Rating Form for Western Washington (Hruby 2014), Wetland C would likely be rated as a Category III wetland (Wetland C, Appendix B). Category III wetlands typically require a 150-foot buffer, depending on the intensity of proposed adjacent land use, according to the Jefferson County (2016) Code. 10 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 Adjacent Uplands The surrounding uplands (coniferous forest) were differentiated from the wetland mainly by the dominance of non-hydrophytic plant species, principally Douglas-fir, salal, red huckleberry, cascade Oregon-grape (Mahonia nervosa), and sword-fern. Scattered western arborvitae, red alder, and western hemlock also are common components of these upland forests. The surrounding uplands also were generally characterized by very grayish brown (10YR 4/2) to yellowish brown (10YR 5/8) or brighter soils, generally without mottles in the ‘B’ horizon within 12 inches of the surface (Sample Plot C-1, Appendix A). At the time of our site investigations, saturation was not evident within the upper 12 inches of the soil profile. Wetland D Wetland D is a small, isolated depression that totals 759 square feet (0.02 acres) and lies approximately 150 feet south of Wetland C according to the results of our baseline investigation report (Raedeke Associates, Inc. 2000). We did not flag this wetland area as part of this study since it is located more than 300 feet from any proposed disturbances at the site. Although it was not flagged as part of this study, Wetland D is still present and found in approximately the same location that it was identified during our baseline investigations. Wetland E Wetland E is a small, isolated depression which according to our baseline investigation report (Raedeke Associates, Inc. 2000) totals 602 square feet (0.01 acres) in area and is located in the southeastern corner of the property, to the west of Wetlands C and D. It was observed to be approximately the same size and in the same location as it was identified in our baseline studies. Vegetation Wetland E consists of a palustrine emergent, persistent (PEM1) vegetation community dominated by slough sedge, violet, marsh speedwell (Veronica scutellata), and common speedwell (Veronica officinalis). Scattered salmonberry, hardhack spirea (Spiraea douglasii), salal, and red huckleberry are interspersed with the larger areas of slough sedge. Wetland E is thus dominated by hydrophytic vegetation. Soils and Hydrology Soils within Wetland E consist of a grayish brown (10YR 5/2) sandy loam surface horizon with yellowish brown (10YR 5/4) mottles, standing water to a depth of at least 8 inches was observed during our 2017 field investigation. At the time of our site investigation, wetland hydrology was observed based on the presence of hydric soils, a dominance of hydrophytic vegetation, and indicators of wetland drainage patterns, including evidence of ponding and scouring (Sample Plot E-2, Appendix A). Thus, 11 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 Wetland E has positive evidence of wetland hydrology and low chroma, mottled soils indicative of hydric soils. Wetland E likely receives hydrology from groundwater seepage and a seasonally perched water table. Classification and Determination Based on our observations, Wetland E meets the necessary criteria for designation as a wetland according to the guidelines of the COE delineation manual (Environmental Laboratory 1987) and the Regional Supplement (COE 2010). This wetland is classified as a palustrine, persistent emergent (PEM1) wetland. Based on the 2014 WDOE Wetlands Rating Form for Western Washington (Hruby 2014), Wetland E would likely be rated as a Category IV wetland (Wetland E, Appendix B). Category IV wetlands typically require a 50-foot buffer, depending on the intensity of proposed adjacent land use, according to the Jefferson County (2016) Code. However, Category IV wetlands smaller than 10,000 feet are not considered designated wetlands under the Jefferson County (2016) ICAO. Such wetlands may still be considered jurisdictional wetlands by the WDOE and COE. Adjacent Uplands Due to their close proximity, the uplands surrounding Wetlands B, C, D, E, and F are essentially the same. These coniferous forests were differentiated from the wetland mainly by the dominance of non-hydrophytic plant species, principally Douglas-fir, salal, Pacific blackberry, cascade Oregon-grape, and sword-fern. Scattered western red cedar, red alder, and western hemlock also are common components of these upland forests. The surrounding uplands also were generally characterized by very dark grayish brown (10YR 3/2) to dark yellowish brown (10YR 4/6) or brighter loam soils, generally without mottles in the ‘B’ horizon within 12 inches of the surface (Sample Plot E-1, Appendix A). At the time of our site investigations, saturation was not evident within the upper 12 inches of the soil profile in these upland areas. Wetland F Wetland F is an isolated depression that totals 27,133 square feet (0.62 acres) in area and is located south and west of Wetland E in the southeastern corner of the property. Vegetation Wetland F consists of palustrine, forested, broad-leaved deciduous (PFO1) and palustrine, emergent, persistent (PEM1) vegetation classes. The emergent community comprises the southern and central portion of the wetland and is dominated by slough sedge, water parsley, pacific water dropwort (Petasites frigidus), and marsh speedwell, with scattered patches of hardhack spirea, western crabapple (Malus fusca), and salal interspersed throughout the wetland. The forested community comprises the western and northern portions of Wetland F and is dominated by red alder and western red cedar trees with an understory of salmonberry, water parsley, Siberian miner’s lettuce (Claytonia 12 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 sibirica), and tall mannagrass. Wetland F is thus characterized by a dominance of hydrophytic vegetation. Soils and Hydrology The soil profile throughout this wetland is generally characterized by a surface horizon of very dark grayish brown (10YR 3/2) silt loam with yellowish brown (10YR 5/4) redoximorphic features. At the time of our site investigation, the soil profile was saturated at the surface within the center of the wetland. The southern and western portions of the wetland were saturated and exhibiting signs of ponding at the time of our site investigation, which confirmed wetland hydrology that was assumed in these portions of the wetland during our previous baseline investigations based on water-stained leaves, evidence of scouring, hydric soil, and a dominance by hydrophytic vegetation. Thus, Wetland F displayed positive evidence of wetland hydrology and low chroma, mottled soils indicative of hydric soils (Sample Plot F-2, Appendix A). Wetland F likely receives hydrology from groundwater seepage, direct precipitation surface water runoff from surrounding uplands, and a seasonally perched water table. Classification and Determination Based on our observations, Wetland F meets the necessary criteria for designation as a wetland according to the guidelines of the COE delineation manual (Environmental Laboratory 1987) and the Regional Supplement (COE 2010). This wetland is classified as a palustrine, forested, broad-leaved deciduous (PFO1) and palustrine, emergent persistent (PEM1) wetland. Based on the 2014 WDOE Wetlands Rating Form for Western Washington (Hruby 2014), Wetland F would likely be rated as a Category IV wetland (Wetland F, Appendix B). Category IV wetlands typically require a 50-foot buffer, depending on the intensity of adjacent land use, according to the Jefferson County (2016) Code. Adjacent Uplands Due to their close proximity, the uplands surrounding Wetlands B, C, D, E, F, Y, and Z are essentially the same. These coniferous forests were differentiated from the wetland mainly by the dominance of non-hydrophytic plant species, principally Douglas-fir, salal, Pacific blackberry, red huckleberry, and sword-fern. Scattered western red cedar, red alder, and western hemlock also are common components of these upland forests. The surrounding uplands also were generally characterized by very dark grayish brown (10YR 3/2) to strong brown (7.5YR 4/6) or brighter soils, generally without mottles within 12 inches of the surface (Sample Plot F-1, Appendix A). At the time of our site investigations, saturation was not evident within the upper 12 inches of the soil profile in these upland areas. 13 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 Wetland Y Wetland Y is a depression that totals 8,410 square feet (0.19 acres) in area and is located north of Wetland F and south of Wetland Z and Stream 6. It is generally located in the northwestern corner of the site parcel number 978802502. Vegetation Wetland Y consists of palustrine, forested, broad-leaved deciduous (PFO1) and interspersed palustrine, emergent, persistent (PEM1) vegetation classes. The emergent community is comprised of slough sedge and pacific water dropwort, with scattered patches of salal and salmon raspberry interspersed throughout the wetland. The forested community is dominated by red alder and western arborvitae trees with an understory of salmonberry, salal, ad slough sedge. Wetland Y is thus characterized by a dominance of hydrophytic vegetation. Soils and Hydrology The soil profile throughout this wetland is generally characterized by a surface horizon of black (10YR 2/1) loam with an underlying “B” soil layer of grayish brown (10YR 5/2) sandy loam with dark yellowish brown (10YR 4/4) redoximorphic features (Sample Plots Y-1 and Y-3, Appendix A). At the time of our site investigation, the soil profile was saturated at the surface with approximately 3 inches of ponding water in the wetland. Thus, Wetland Y displayed positive evidence of wetland hydrology, and low chroma, mottled soils indicative of hydric soils. Wetland Y likely receives hydrology from groundwater seepage, direct precipitation surface water runoff from surrounding uplands, and a seasonally perched water table. It generally drains by overland flow when flooded to the north toward Stream 6. Classification and Determination Based on our observations, Wetland Y meets the necessary criteria for designation as a wetland according to the guidelines of the COE delineation manual (Environmental Laboratory 1987) and the Regional Supplement (COE 2010). This wetland is classified as a palustrine, forested, broad-leaved deciduous (PFO1) and palustrine, emergent persistent (PEM1) wetland. Based on the 2014 WDOE Wetlands Rating Form for Western Washington (Hruby 2014), Wetland Y would likely be rated as a Category III wetland (Wetland Y, Appendix B). Category III wetlands typically require a 150-foot buffer, depending on the intensity of proposed adjacent land use, according to the Jefferson County (2016) Code. 14 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 Adjacent Uplands Due to their close proximity, the uplands surrounding Wetlands B, C, D, E, F, Y, and Z are essentially the same (Sample Plot Y-2, Appendix A). Refer to the descriptions of uplands around nearby wetland areas that are previously discussed in this report. The surrounding uplands also were generally characterized by brighter soils without mottles within 12-18 inches of the surface and similar to the uplands around nearby wetland areas. Wetland Z and Stream 6 Wetland Z is a depression that totals 1,276 square feet (0.03 acres) in area and is located north of Wetland Y and east of Stream 6 in the northwestern corner of the site parcel number 978802502. Stream 6 generally drains south to north through a culvert under the Mount Wilder Way roadway. Vegetation Wetland Z is comprised of palustrine, scrub-shrub broad leaved deciduous (PSS1) vegetation class. The community is dominated by salmonberry throughout. Wetland Z is thus characterized by a dominance of hydrophytic vegetation. Soils and Hydrology The soil profiled throughout this wetland is similar to that of Wetland Y. The profiled consisted of shallow dark surface of black (10YR 2/1) sandy loam with underlying dark grayish brown (10YR 4/2) sandy loam with dark yellowish brown (10YR 4/4) mottles, inundated to a depth of approximately 3 inches throughout the wetland (Sample Plot Z-1, Appendix A). Thus, Wetland Z displayed positive evidence of wetland hydrology and low chroma, mottled soils indicative of hydric soils. A nearby stormwater pond also contributes hydrology to this wetland area. Classification and Determination Based on our observations, Wetland Z meets the necessary criteria for designation as a wetland according to the guidelines of the COE delineation manual (Environmental Laboratory 1987) and the Regional Supplement (COE 2010). This wetland is classified as a palustrine scrub-shrub broad leaved deciduous (PSS1) wetland. Based on the 2014 WDOE Wetlands Rating Form for Western Washington (Hruby 2014), Wetland Z would likely be rated as a Category III wetland (Wetland Z, Appendix B). Category III wetlands typically require a 150-foot buffer, depending on the intensity of proposed adjacent land use, according to the Jefferson County (2016) Code. 15 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 Stream 6, according to Jefferson County GIS mapping information, is mapped as a non- fish habitat stream with a 75-foot stream buffer requirement per Jefferson County (2016) Code. Based on observations during this investigation and previous investigations, the stream appears to flow seasonally. Adjacent Uplands Due to their close proximity, the uplands surrounding Wetlands B, C, D, E, F, Y, and Z are essentially the same (sample Plot Z-2, Appendix A). Refer to the descriptions of uplands around nearby wetland areas that are previously discussed in this report. The surrounding uplands also were generally characterized by brighter soils without mottles within 12-18 inches of the surface and similar to the uplands around nearby wetland areas. 3.2.2 Phase I Wetlands Adjacent to or Offsite of The Phase II Area Wetlands A, C, and F continue off site from the investigated parcels. We did not identify any other wetlands adjacent to or offsite that were of concern for the proposed development of Olympic Terrace II – Phase II area other than the wetlands described in the previous section of this report. Wetlands located in the remainder of the Olympic Terrace project area, including Olympic Terrace I that is currently under construction, were not delineated during these 2017 field investigations. Only the areas nearest the proposed project development, within 300 feet, were investigated for wetlands, streams, and habitats. Refer to the results presented in the baseline investigations performed by Raedeke for more information regarding wetlands located around the current project site (Raedeke Associates, Inc. 2000). Wetlands identified as part of our 2000 baseline investigations may not be relied on for purposes of this report. However, for general understanding of the overall Olympic Terrace property, previously delineated wetlands are shown on Figure 2 of this report. 16 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 4.0 REGULATORY CONSIDERATIONS Wetlands and streams are protected by Section 404 of the Federal Clean Water Act and other state and local policies and ordinances, including the Jefferson County (2016) code. Regulatory considerations pertinent to wetlands and streams at the site are subject to Federal, State, and Jefferson County (2016) Critical Areas Regulations discussed below; however, this discussion should not be considered comprehensive. Additional information may be obtained from agencies with jurisdictional responsibility for, or interest in, the site. A brief review of federal and state regulations and Jefferson County policy, relative to wetlands, is presented below. 4.1 FEDERAL CLEAN WATER ACT (U.S. ARMY CORPS OF ENGINEERS) Federal law (Section 404 of the Clean Water Act) discourages the discharge of dredged or fill material into the nation's waters, including most wetlands and streams, without a permit from the U.S. Army Corps of Engineers (COE). We note that certain wetlands, including many that are hydrologically isolated from “Waters of the U.S.,” may not be regulated by the COE. The COE makes the final determination as to whether an area meets the definition of “Waters of the U.S.” as defined by the federal government (Federal Register 1986:41251), and thus, if it is under their jurisdiction. We should caution that the placement of fill within wetlands or other “Waters of the U.S.” without authorization from the COE is not advised, as the COE makes the final determination regarding whether any permits would be required for any proposed alteration (COE 2012). Therefore, we recommend requesting a jurisdictional determination from the COE prior to any construction activities, if any modification of wetlands or streams is proposed. A jurisdictional determination would also provide evaluation and confirmation of our delineation by the COE. 4.2 STATE OF WASHINGTON Under Section 401 of the Clean Water Act, an activity involving a discharge in waters of the U.S. and authorized by the COE must also receive certification that the federally permitted activity complies with the federal Clean Water Act, state water quality laws, and any other appropriate state laws (such as the Water Resources Act and Hydraulic Code). In Washington State, the certifying agency is usually the Washington Department of Ecology (WDOE). In addition, if the COE-authorized permit is for actions within the 15 coastal counties, including Jefferson County, then the WDOE must confirm or deny that the proposed action complies with the Washington Coastal Zone Management Program. The WDOE also regulates activities within isolated wetlands under the state Water Pollution Control Act (90.48 RCW) and the Shoreline Management Act (90.58 RCW) in instances where a wetland or water is determined to be non-jurisdictional by the COE. The standards of review for issuance of a permit by the WDOE for activities 17 Olympic Terrace II Raedeke Associates, Inc. Wetland Delineation Update May 17, 2017 within non-COE-jurisdictional wetlands or waters are the same as those for Section 401 certifications. 4.3 JEFFERSON COUNTY Jefferson County (2016) code regulates wetlands and streams as critical areas. Alterations of wetlands or streams and their buffers are generally prohibited, except as allowed under certain conditions. All direct wetland impacts must be mitigated through wetland creation, restoration, or enhancement. Jefferson County (2016) has the final authority to determine ratings, buffers, and allowed uses of wetlands, their buffers, and other sensitive areas that are under their jurisdiction. We rated all wetlands within the project areas using the 2014 WDOE Wetland Rating System for Western Washington (Hruby 2014), as required and clarified by Jefferson County (2016) code for determination of wetland buffer widths and mitigation ratios (see Appendix B) and Ms. Donna Frostholm of Jefferson County Department of Community Development via email on April 3, 2017 (Frostholm, pers. comm. 2017). Jefferson County (2016) also regulates streams as “Fish and Wildlife Habitat Conservation Areas” under Title 18 Chapter 18.22 Article VI. Table 2 provides a list of wetlands and streams within the project area and their probable ratings and corresponding buffers. 18 Olympic Terrace II Raedeke Associates, Inc.

NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe 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 an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2.The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – 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 all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4.Does 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. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 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 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. 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. Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 NO – go to 6 YES – The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 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 means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – 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 classes. 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 IN 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 the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM 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. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable 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.

Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High Conservation Value? Yes – Go to SC 2.2 No – Go to SC 2.3 SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value? Yes = Category I No = Not a WHCV SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland? http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf Yes – Contact WNHP/WDNR and go to SC 2.4 No = Not a WHCV SC 2.4. Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on their website? Yes = Category I No = Not a WHCV Cat. I SC 3.0. Bogs Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key below. If you answer YES you will still need to rate the wetland based on its functions. SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or more of the first 32 in of the soil profile? Yes – Go to SC 3.3 No – Go to SC 3.2 SC 3.2. Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or pond?
