Field work was conducted on March 2, 2020 to determine the wetland boundary and rating of a wetland as mapped on the Jefferson County Critical Areas Map. The wetland boundaries are accurate within 5 feet as determined by topography, soils, and vegetation. Project Proposal The project proposal includes installing a septic for a single family residence that will be designed by Everett Sorenson. Currently there is an existing homesite that will be expanded to accommodate a larger home. John Colden owns the parcel and this delineation and buffer determination will determine development potential. Site Description and Existing Conditions The parcel slopes gently west towards Fort Flagler Road (SR 116). Jefferson County Critical Areas map indicates a small wetland on the lower elevations near the road. This wetland is shown to extend south to adjacent parcels. The majority of the parcel is forested with an understory of native shrubs and herbaceous species. + Legal Description: Parcel 976 201402, Section 33, Township 30N, Range lE ■ WRIA 17 Sub Basin 2014 Indian/Marrowstone • Zoned RR-5 ■ Soils: DaCDabob very gravelly loam and Casey silt Loam • Location: 6.1 miles from Port Hadlock and 1/2 mile from Nordland Store • Slopes 0 to 8%, 1.67 acres, elevations 10 to 60' At the end of this report are the following: Figure 1 Location, Contour, Aerial, Critical Areas, and Soils Figure 2 Findings of Wetland Delineation Figure 3 1 KM Polygon for Rating Form. Methodology Due to the mapped wetlands on this parcel this Wetland Delineation and Analysis is required by Jefferson County Environmental Health and DCD as part of the permit application process. This assessment is prepared according to the current Unified Development Code, Chapter 18.22, Critical Areas (18.22.270, 18.22.330, 18.22.440 and 18.22.450) with updates from March 10, 2020. The characteristics of an area that result in its classification as "wetland" have been formally defined by federal and state agencies. All wetland delineations must be prepared in accordance with the U.S. Army Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region, Version 2.0 (May 2010) John Colden Wetland Delineation and Analysis Report File 2020-0220 March 2020 Complete Methodology used for this delineation and HMP are included at the end of this r port. -� Background Information The following resources were consulted prior to field work for this project: 1�91 '�C�, • Jefferson County UDC Chapter 18 Critical Areas (updated March 2020)����''rpr • Washington Department of Fish and Wildlife Priority Habitat Species (PHS) Aerial Photographs (Google Internet) • Soil Survey (https://websoilsurvey.sc.egov.usda.gov/App/flomePage.htm) ■ Washington State Wetland Identification and Delineation Manual (1997) • National List of Plant Species That Occur in Wetlands: Northwest (Region 9) (2019 name update) Wetland Delineation Findings This delineation follows a wet spring during the early start of the growing season. Vegetation was mostly dormant with minimal leaf budding. Air and temperature were from 43' to 41' (soils at 16" below the surface). Determining a wetland edge is difficult during early spring due to seasonal high water table and dormant herbaceous species. It is advised to re-examine the site later in the spring when the water tables are stable. The Jefferson County Critical Areas map indicates only a small area in the western end the 1.6 acre parcel is mapped as wetland. This area is along Flagler Road historically be due to the elevation and construction of Fort Flagler Road interrupting and capturing the flow of stormwater towards Mystery Bay. NRCS soil maps do not indicate hydric soils on site. (Figure 1). The wetland edge was determined by examining soils, vegetation layers, and hydrology at each data point. The wetland boundary is defined by a slight drop in topography, change of vegetation (predominantly FAC), the presence of redoximorphic features in the soils, and the presence of hydrology both in the pit and ponding nearby. Findings reveal the wetland edge corresponds roughly with the Jefferson County Critical Areas wetland map. Once the wetland edge was established it was flagged at 20' to 30' intervals. The Findings Map (Figure 2) includes the property boundaries, delineated wetland edge, associated buffers, and data point locations overlaid on an aerial photograph with 5'contours (Google). Soils NRCS Soil Survey (internet) lists all soils on the subject parcel as DaC Dabob very gravelly loam and Casey silt Loam. Findings were relatively consistent with this soil description as observed in the 5 data points and soil test pit locations. The Soil matrix color in Data Points 1, 2, and 4 were very dark brown (1 OYR 2/2) with no redoximorphic features. Below 6 to 9" soils were greyish brown and sandy (1 OYR 5/2) with abundant redoximorphic features in a loamy clay layer (1 OYR 4/4). Water or soil saturation was only observed at the bottom inch or less of the 16" soil test pits. Data Point 3 was slightly upslope to the east and did not contain hydric soils. The soil matrix color was black 1 OYR 2/1 overlaying a light brown soil 1 OY/R dry soil. Data Point 3 is clearly outside the wetland. John Colden Wetland Delineation and Analysis Report File 2020-0220 2 March 2020 Data Point 5 was 40 feet to the east of Flagler road and had wetland soils. There was a mature Douglas fir with an understory of shrubs that clearly defined the wetland/upland boundary. Vegetation This wetland delineation was conducted during very early spring when most vegetation was in bud or starting to show leaf budding. Trees and shrubs were identified by familiarity of branching, bud formation, and residual leaves on the ground. There is a healthy understory of shubs with down branches that provide habitat for many species. There were very few non-native species. Most species on the parcel are rated as FAC and can also be found in uplands. The dominant vegetation and percent cover are recorded on the Data Forms at the end of this Below is the list of vegetation identified during the early March assessment and include the a indicator status of each species.

Surface ponding and soil saturation were observed near Flagler Road. Due to a recent series of storms with'signiflcant rainfall the water table was potentially higher than normal and the drainage ditch along Flagler Road had flowing water. All water from this site will eventually end up in Mystery Bay less than 1 iiie. from the parcel. ! o Wetland Analysis � cry Categorization and Buffers This wetland unit on Colden's parcel falls along Flagler Road. The rating for this wetland unit received.':, 16 points based the following: Improving Water Quality (6 points), Hydrologic Function (5) points, and ' Habitat (5points) for a total of 16 points. Wetlands with a rating of 16 points and 5 points for Habitat qualify as a Category III Wetland and have associated 60 foot buffers as indicated in the table below. Buffers are measured perpendicular from the delineated edge as indicated on the Findings Map (Figure 2). The proposed septic system/reserve and single-family residence are on a parcel larger than one acre and are defined as "moderate impact land- use". All development should be planned outside of wetland buffers. The Wetland Rating Form is included in the Appendix at the end of this report. Show below is the adopted critical areas update March 11, 2020 for wetland boundaries. This delineated wetland with a Habitat score of 5 with Moderate Land Use Impacts with have 60 foot buffers.

The subject parcel rises slightly upslope to an elevation of 30 to 40 feet above Flagler Road which is near sea level. Marrowstone is relatively flat with no significant elevation and harbors several wetland areas due to glacial compacted soils. Potential Impacts of Proposed Development Short-term impacts during the septic installation and completion of the house will be minimized by careful construction practices. Quantities of excavated soils for the septic system and the final design for the single-family residence will be discussed in detail in the final plans. All other impacts and impervious surfaces will be addressed when the final plans are submitted. All construction will take place outside of delineated buffers and are over 150 feet from the waters of Mystery Bay. There will be "No Net Loss" of any ecological functions during or after construction. The proposed building envelope consists of an existing cabin and no trees will be removed for the new homesite. Due to the gently sloping landscape there will be no potential for erosion or siltation entering Mystery Bay or the delineated wetland. Best Management Practices (BMPs) should be followed during and after construction. There will be no alteration of surface water flows since the site is moderately sloped, well drained and final contours will follow the original slopes in the landscape. John Colden Wetland Delineation and Analysis Report File 2020-0220 5 March 2020 Limitations The final authority over approval of this Wetland Delineation and Categorization Buffer will be Jefferson County DCD and Department of Environmental Public Health. Final jurisdictional authority over wetland, shoreline, and buffer determinations rests with the local, state and federal agencies. If there are further questions or planning requirements for this project, please do not hesitate to call. Summary Olympic Wetland Resources, LLC conducted a Wetland Delineation and Analysis for John Colden on his parcel located near Nordland Washington on March 2, 2020. The proposed project includes the installation of a septic system and permitting of a single-family residence. Findings from this report include a Category III wetland with 60-foot buffers. The final site plan will indicate the building envelope and septic location outside all wetland buffers.

All wetland delineations must be prepared in accordance with the U.S. Army Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region, Version 2.0 (May 2010). The wetland delineation report will include how the wetland boundary was determined and include a map of the delineated wetland, data sheets, and descriptions of site characteristics in both upland and wetland. The methodology outlined in the Corps Manual is based upon three essential characteristics of wetlands: (1) hydrophytic vegetation; (2) hydric soils; and (3) wetland hydrology. Field indicators of these three characteristics must all be present to determine that an area is a wetland (unless problem areas or atypical situations are encountered). All wetlands identified using this methodology may be regulated regardless of size. Determining Wetland Edges Wetland edges were determined by establishing pairs of data points. In general, the wetland edge falls between the sampling plot with all three positive wetland requirements and where one or all of the requirements were not present. Other difficult situations encountered in identifying wetlands are described in greater detail in the Corps Regional Supplement. Hydrophytic Vegetation Hydrophytic vegetation decisions are based on communities of species that tolerate prolonged inundation or soil saturation during the growing season. Vegetation sampling will follow the guidance outlined in the Corps Manual. Several methods can be applied; however, one method includes recording vegetation of a sampling point to determine if more than 50% of the dominant species have a wetland indicator status of OBL, FACW, or FAC. Dominance of plant species is determined by calculating actual aerial cover within an appropriate radius for trees, shrubs, and herbaceous species at each data point. Commonly occurring plant species have been rated by the U.S. Army Corps of En insets Nations! Wetland Plant List (NWPL). 2014 COE Western Mountains, Valleys, and Coast. During the fieldwork, each species was recorded and given a rating based on indicator status and percent cover. The 2014 NWPL will be used in any wetland delineations or determinations performed after May 1, 2014. Key to Wetland Indicator Status codes — Northwest Region (Source: USFWS, 1988, 1993): OBL Obligate: species that almost always occur in wetlands under natural conditions (est. probability >99%). FACW Facultative wetland: species that usually occur in wetlands (est. probability 67 to 99%), but are occasionally found in non -wetlands. FAC Facultative: species that are equally likely to occur in wetlands or non -wetlands (est. probability 34 to 66%). FACU Facultative upland: species that usually occur in non -wetlands (est. probability 67 to 99%), but are occasionally found in wetlands. UPL Upland: species that almost always occur in non -wetlands under normal conditions (est. probability >99%). NL Not listed: species that are not listed by USFWS (1988, 1993) and are presumed to be upland species. NI No indicator: species for which insufficient information is available to determine status, or which were not evaluated by USFWS. Hydrophytic Soil A hydric soil is a soil that forms under conditions of saturation, flooding, or pondind"ll"sting long enough ' during the growing season to result in an anaerobic upper layer (USDA-NRCS 1995). Hydric soils favor ri the growth and regeneration of hydrophytic vegetation. The Natural Resources Conservation Service (NRCS), in cooperation with the National Technical Committee for Hydric Soils, has compiled lists of hydric soils. It is common, however, for a map unit of non -wetland (non-hydric) soil to have inclusions of hydric soil, and vice versa. Therefore, field examination of soil conditions is important to determine if hydric soil conditions exist. In general, anaerobic conditions create certain characteristics in hydric soils, collectively known as "redoximorphic features" and include low chroma, depletions, gleying, sulfidic material (rotten egg odor) and/or high organic content within the soil immediately below the A -horizon. Holes were dug on the site and soil colors were described by texture, color name, value, and chroma (Munsell Color 2000). Soils were categorized in accordance with NRCS Field Indicators of Hydric Soils of the United States (Version 7.0, 2010 with updates). This manual further defines organic soils, sandy soils, loamy and clayey soils with a numeric value. Wetland Hydrology Water must be present in order for wetlands to exist; however, it need not be present throughout the entire year. The standard requires 14 or more consecutive days of flooding, or ponding or a water table 12" or less below the soil surface during the growing season. The growing season has begun when two or more different non -evergreen vascular plants are identified. Indicators of hydrology may include, but are not necessarily limited to, ponded water, drainage patterns, drift lines, sediment deposition, historic records, water -stained leaves, cracking of the soil surface, oxidized root channels, and/or sediment deposits. The Regional Supplements provide methods for evaluating situations in wetlands that periodically lack indicators of wetland hydrology but where hydric soils and hydrophytic vegetation are present. Categorization Wetland categorization is determined using the Washington State Department of Ecology (DOE) Wetland Rating System Revised (Ecology Publication #14-06-029, Effective January 2015 and as amended), according to type and category of wetland. The wetland is assigned a score of High, Medium, or Low for wetland values; including water quality function, hydrologic function, and habitat function. The total rating determines the category of wetland. Wetlands are rated as entire systems and quite often exceed project boundaries. Ratings range from Category I to Category IV. Buffers are assigned according to intensity of land use for specific parcel size using final numeric scores. Category I indicates wetlands with the highest quality of function for improving water quality, preventing flooding problems, and providing habitat. These are not replaceable and therefore receive the largest buffer and highest protection. Classification Two classification systems are commonly used to describe wetlands. The hydrogeomorphic (HGM) system describes wetlands in terms of their position in the landscape and the movement of water in the wetland (Brinson, 1993). The U.S. Fish and Wildlife Service classification system (Cowardin et al., 1979) describes wetlands in terms of their vegetation communities; for example, emergent (PEM), scrub- (PSS) shrub, and forested (PFO) community types.
