The wetland edge was delineated and the 50' buffer established. This small, degraded wetland appears to have been a result of past logging road construction in2004. The proposed developments include the installation an asphalt driveway with utilities (water main, hydrant, electric communications conduit, and stormwater management features) along the undeveloped portion of Katherine Street. f"hese street improvements would service two proposed houses on Block l5 and the southem portion of Block 14 as shown on the Sorensen site plan. As requested by the City, additional data is required during the wet season to determine if there is a change in the wetland size or location, Field work was conducted on February 2,2021 after a significant rain event of over one inch of precipitation the previous day. The focus of the field work was to determine the proximity of the eastern wetland edge (if there were changes) in relationship to the proposed Kathrine Street development. Although the entire area was observed for additional water ponding, the focus was on the eastern porlion of Lots 7 and 8. Findings from this wet-season evaluation determined there are no significant changes in the wetland size or location of boundaries. It is still within the swale created by the logging road and a distinct vegetation change from sedge to upland species (salal, Douglas fir, and Madrone). Once again using a hip chain the site was measured betweeu the eastern edge of the wetland (Lots 7 and 8 Block 14 Parcels 959 70I40I) and the western edge of the proposed Katherine Street development. The development is 96 feet from the wetland edge and well out of the 50 foot buffer of this small Category IV roadside wetland.

The project consists of 3 parcels and is bisected by Katherine Street. Field work was conducted on July 8th and August 7,2019 to determine the presence of wetlands, wetland rating, and potential buffer restriction to proposed building envelopes. Several subsequent updates in the rating system and City of Port Townsend Critical Area Code (May 201S) will regulate all wetlands no matter how small. Previous to the Code update wetlands under 1,000 sqft were exempt. 19.05.1 l0 (B. 4d) Category IV wetlands have the lowest levels of functions (scores less than 16 points) and are often heavily disturbed. These are wetlands that are capable of being replaced, and in some cases improved. However, experience has shown that replacement cannot be guaranteed in any specific case. These wetlands may provide some important functions, and should be protected' Project Proposal The project includes the development of utilities to all parcels down the undeveloped portion of Kathrine Street that runs between parcel 959701501 to the east and parcels 959701401and 95940140 to the west. The parcels are in the planning phase to determine potential site location for single family homes in relationship to the critical areas and buffer restrictions.

Methodology Methodology used for this delineation and buffer categorization include the May 2018 update ofthe Port Townsend Municipal Code and current state and federal jurisdictions. The characteristics of an area that result in its classification as "wetland" have been formally defined by federal and state agencies. Al1 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 Background Information The following resources were consulted prior to field work for this project: o City of Port Townsend Municipal Code. Title 19 Environmental Protection Chapter 19.05 Critical Areas (19.05) May 21,2018 o Clty of Port Townsend Critical Areas Map (2016) o Aerial Photographs (Google lntemet) o Soil Survey (https://websoilsurvey.sc.egov.usda.gov/App/tlomePage.htm) o Washinglon State Wetland Identification and Delineation Manual (1997) o National List ofPlant Species That Occur in Wetlands: Northwest (Region 9) (2019) Wetland Delineation Findings A small -660 sqft wetland was identified along the access driveway (logging road) east of Cliff Street and on Parcel 959701401at the top of Basin 4. The Findings Map (Figure 2) includes property boundaries, delineated wetland edge, associated buffers, and data point locations overlaid on a site plan prepared by Everett Sorensen, PE. This small wetland is defined by a slight drop in topography potentially caused by road construction. Once the wetland boundary was established it was flagged at l0 foot intervals (A1- A4). The wetland edge was determined by examining soils (redoximorphic features), vegetation layers (Obligate and Facultative wetland vegetation), and hydrology. Wetlands are often located in the glacial soils of the Clallam soil types throughout Port Townsend due to the lateral movement of stormwater on the compact glacial cement layer. This delineation was conducted in July/August after below average rainfall in the spring and summer and hydrology was not present. To confirm hydrology a wet season evaluation could be done in the early spring months. Soils NRCS Soil Survey (internet) lists all soils on the parcels as CmC Clallam gravelly sandy loam and TnC Townsend gravelly loam. Finding were relatively consistent with this soil description. The Soil matrix color in Data Point I (DP 1) was dark greyish brown (Munsell soil color 10YR 312)wtth redoximorphic features in the lower parts (1OYR 416). The vegetation layer was dominated by upland plant communities in all vegetation layers. Sorensen Wetland Delineation Report File #2019-0710 2 July/August 2019 Data Point 2 (DP 2) was adjacent to the access driveway and consisted of matrix dark gray brown (Munsell 10yR 4l2abovesoilscolors 10YR 5l2andredoximorphic 10YR4i6). Thisdatapointiswithinthe wetland supported by the dominance of wetland vegetation in all plant communities. Soils in Data Point 3 (DP 3) conesponded with findings in DP 1. and were dry and is also dominated by upland vegetation. Redoximorphic features were observed in all data points under 2'7 inches below the top layer and above the cement layer (photograph Figure 3). Vegetation The majority of the three parcels are dominated by upland vegetation unable to tolerate regular saturated conditions. The plant community is dominated by an overstory of Douglas fir, Madrone, and red cedal with a very dense understory of salal, oceanspray and bracken fern. Scouler's willow is scattered in both upland wetland sites. The small wetland had over 90Yo wefiland vegetation in a plant community that included slough sedge, Nootka rose, spirea, and willow.

WA State Sorensen Wetland Delineation Report File #2019-0710 J July/August 2019 Hydrology Hydrology was not present even within the wetland data point which is common this time of year. Hydrology can be assumed where obligate and facultative vegetation are identified. The majority of the thr.ee parcels are dominated by upland vegetation. It is common in disturbed or excavated areas for stormwater to flow laterally and create ponding during the wet season. Wetland Analysis and Critical Areas Review Categori zation a nd Buffers The standard buffer width for a delineated Category IV Wetlands for parcels under 1 acre is 50' as highlighted in the table below. The wetland was categorized using the standard wetland analysis that examines Water Quality, Hydrologic Function, and Habitat features. The Wetland Rating Form is included in the Appendix at the end of this report. A single-family residence is considered "high impact land-use'o when it is on a parcel smaller than one acre. The rating for Improving Water Quality is 4 points, Hydrologic Function 4 points, and Habitat 3 points (total of l1 points). All buffers are measured perpendicular from the delineated edge. Habitat and Species Assessment Washington Department of Fish and Wildlife Priority Habitat and Species were evaluated within 1i3 of a mile of this parcel. All threatened or endangered plant or animal species were recorded and if possible surveyed during the October 2018 assessment. The only listing is Freshwater Emergent Wetlands near this parcel. Watershed and Hydrologic Assessment Since these parcels are at the top of 3 basins as defined by the City of Port Townsend all water will drain downslope. The small wetland is within Basin 4 where many wetlands are identified. Since there is no outlet there is no chance of downslope flooding. It is in the WRA Quimper Peninsula Sub Basin 2014 wRrA #17.

Large trees along the undeveloped Katherine Street will be avoided as much a possible when installing water, sewer and other utilities. Short-term impacts during the installation of the utilities will be minimized by careful construction practices. All proposed construction will be located outside the 50' buffer of the delineated wetland. There will be "No Net Loss" of any ecological functions during or after construction. Due to the flat landscape there will be no potential for erosion or siltation to the 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 well drained and final contours should follow the original landscape. Limitations The final authority over approval of this Wetland Delineation and Categorization will be the City of Port Townsend Development Services Department. Final jurisdictional authority over wetland, shorelineo 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 A 660 sqft wetland was categorized and delineated in July/August 2019 to determine development restrictions for the installation of utilities (down the undeveloped portion of Katherine Street) and the construction of homes on the undeveloped parcels owned by Everett Sorensen. The parcels are transected by social trails and contained cleared areas for easy assessment of potential wetland conditions. The only wetland identified was a ditch associated with the current access driveway off of Cliff Street. This was once a logging road constructed in 2004 and potentially contributed to the soil disturbance and water accumulation for this small wetland. Wetland soils were identified throughout the site as indicated by redoximorphic features below the top layer of soil from 2to 7 inches within the soil test pits. The only area with a dominance of wetland vegetation was along the driveway and was delineated and flagged. It qualifies as a Category IV wetland with 50 foot buffers.

The characteristics of anareathatresult 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 Wreiland 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 andwetland. The methodology outlined in the Corps Manual is based upon three essential characteristics of wetlands: (l) hydrophytic vegetation; (2) hydric soils; and (3) wetland hydrology. Field indicators of these three characteristics must all be present in order 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. ln general, the wetland edge falls between the sampling plot with all three positive wetland requirements and where one or all ofthe requirements were not present. Other difficult situations encountered in identi$ing wetlands are described in greater detail in the Corps Regional Supplement. Hy drop hytic Vegetatio n Hydrophytic vegetation decisions are based on cornmunities 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 50o/o 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 Engineers National Wetland Plant List (NWPL). 2014 COE Western Mountains. Vallq)s, and Coast. During the fieldwork, each species was recorded and given a rating based on indicator status and percent cover. The2014 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 >gg%). FACW Facultative wetland: species that usually occur in wetlands (est. probability 67 to 99%o), 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 99Yo), but are occasionally found in wetlands. UPL Upland: species that almost always occur in non-wetlands under normal conditions (est. probability >99o/o). Hydric Soil A hydric soil is a soil that forms under conditions of saturation, flooding, or ponding lasting long enough during the growing season to result in an anaerobic upper layer (USDA-NRCS 1995). Hydric soils favor the growth and regeneration ofhydrophytic 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 irihydric soils, collectivply known as "redoximorphic features" and include low chrom4 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 accordancewithNRCs FieldlndicatorsofHydricsoilsoftheUnitedStates(VersionT.0,20l0withupdates). This manual further defines organic soils, sandy soils, loamy and clayey soils with anumeric 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 pattems, 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 categoization is determined using the Washington State Department of Ecologt (DOE) Wetland Rating System Revised (Ecologt 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 frrnction, hydrologic firnction, andhabitat 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. Bufferb 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 qualrty, preventing flooding problems, and providing habitat. These are not replaceable and therefore receive the largest bufler 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.
