The Site and the surrounding 300 feet are referred to jointly as the “Study Area”. This critical areas report has been prepared to comply with the requirements of the City of Port Townsend’s Municipal Code (PTMC) §19.05.110 - Critical area 5 – Wetland and PTMC §19.05.110.K – Special Reports for the purposes of Site development. PROPERTY LOCATION The Site is a single, Jefferson County tax parcel (95970-1904) with no established address. The Site is located along Eddy Street in the City of Port Townsend, Washington at approximately latitude: 48.1232 and longitude: -122.8036. The Public Land Survey System location of the Site is the northeastern quarter of Section 04, Township 30 North, Range 01 West, of the Willamette Meridian. PROPERTY DESCRIPTION AND LAND USE The Site is a 0.12-acre undeveloped single-family residence parcel. The Site is undeveloped with any structures but contains one small quarry spall area that acts as a connection to Eddy Street for the future construction project. The Site contains mixed deciduous and coniferous forest species with relatively dense underlying scrub shrub and herbaceous strata. Small areas onsite also contain patches of invasive Himalayan blackberry (Rubus bifrons). The Site is bordered to the north, south, and east by partially forested single-family residence parcels, and to the west by Eddy Street. Vegetation identified onsite includes, but is not limited to, western redcedar (Thuja plicata), red alder (Alnus rubra), Douglas-fir (Psuedotsuga menziesii), bigleaf maple (Acer macrophyllum), one- seed hawthorn (Crataegus monogyna), Himalayan blackberry (Rubus bifrons), salmonberry (Rubus spectabilis), pea-fruit rose (Rosa pisocarpa), trailing blackberry (Rubus ursinus), common ladyfern (Athyrium filix-femina var. cyclosorum), creeping buttercup (Ranunculus repens), orchard grass (Dactylis glomerata), soft rush (Juncus effusus), yellow archangel (Lamium galeobdolon), common dandelion (Taraxacum officinale), and Robert’s herb (Geranium robertianum). Topography onsite is relatively flat with a light slope downwards from the east to the west. The lowest elevation onsite is located along the western Site boundary, adjacent to Eddy Street, at approximately 234 feet. The highest elevation onsite is situated along the Site’s eastern property boundary at approximately 240 feet. METHODOLOGY The Study Area was evaluated for the presence of critical areas on 28 October 2025 using the routine approach described in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (U.S. Army Corps of Engineers, 2010) and the Washington State Department of Ecology’s publication, Determining the Ordinary High Water Mark for Shoreline Management Compliance in Washington State (2016). Offsite areas were evaluated from what could be observed visually from the boundary of the Site, public rights-of-way, and via agency databases. Wetlands were classified per PTMC §19.05.110.B and their buffers assigned in accordance with PTMC §19.05.110.G. Plant species were identified according to the taxonomy of Flora of the Pacific Northwest (Hitchcock and Cronquist 2018). Taxonomic nomenclature was updated by the U.S. Army Corps of Engineers National Wetland Plant List (Lichvar and Kartesz 2016). Wetland classes were determined per the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin 1979). Hydrophytic vegetation was determined using the standard procedures described in the Army Corps of Engineers (Corps) Regional Supplement, which requires use of the dominance test, except when positive indicators of wetland hydrology and hydric soils are met, in which case the prevalence index or alternative indicators of hydrophytic vegetation may also be required. Wetland hydrology was determined based on the presence of hydrologic indicators listed in the Army Corps of Engineers (Corps) regional supplement. Hydrology indicators include both Primary Indicators and Secondary Indicators. To meet the definition of wetland hydrology, one Primary Indicator or two Secondary Indicators must be observed. Examples of wetland hydrology indicators include but are not limited to: drainage patterns drift lines, sediment deposition, watermarks, stream gauge data and flood predictions, historic records, visual observation of saturated soils, and visual observation of inundation. Soil test pits were excavated to a depth of at least 20 inches below the soil surface to categorize and describe soil and hydrologic conditions within the Study Area. Soils on the Site were considered hydric if one or more of the hydric soil indicators listed in the Corps Regional Supplement were present. Examples of hydric soil indicators include: presence of organic soils, reduced matrix, depleted or gleyed soils, or redoximorphic features in association with a reduced soil matrix. Soil colors were determined using the Munsell Soil Color Charts (Munsell Color 2009). Wetland Determination Datasheets were recorded within representative locations on the Site (Attachment 1). Attachment 2 contains wetland rating forms used to categorize wetland(s) within the Study Area. Climatic conditions were evaluated through the Army Corps of Engineers Antecedent Precipitation Tool application (Attachment 3). Climatic conditions during the Site visit were wetter than normal. Photos are located at the end of the report, before the figures section. ONSITE INVESTIGATION RESULTS One (1) wetland (Wetland A) was identified offsite to the north of the Site but within the Study Area during the 28 October 2025 evaluation (Figure 1). One potential wetland area is estimated offsite to the south according to the City of Port Townsend’s ArcGIS mapper (Photo 1). This potential feature contains a note on the interactive mapper which states “Sketched from 2017 Aerial”; however, no such wetland is present in this location as depicted in Photo 2 from in-field verifications. No other critical areas were identified within the Study Area. Wetland A is described below in Table 1 and the following section. Table 1. Critical Areas Summary Table. Critical Area Category / Type HGM / Cowardin Class Standard Buffer* Wetland A (840-sf, 0.02-acres) Category IV, Habitat Score 4 Depressional/ Forested 50 feet**(***) *Per PTMC §19.05.110.G.9, “Building setback lines shall be measured from the outside edge of required buffers and no setback shall be less than 15 feet from an established wetland buffer”. **Land use intensity has been assigned in accordance with Table §19.05.110(B) - Land Use Impacts and Intensity Levels. Residential parcels zoned for more than 1 d.u. per acre are considered “High” impact. The Subject Property is zoned for “R-I – Low Density Single-Family” which accommodates up to four dwelling units per 40,000-square-foot area or >1 d.u. per acre. ***According to PTMC §19.05.110.D.5, the director may exempt the wetlands that are less than 4,000 sf in area that are not associated with riparian areas and/or shorelines of the state and their associated buffers, are not part of a wetland mosaic, do not score at least 6 or more points for habitat, and do not contain priority habitats or a priority area for priority species. WETLAND A Wetland A is approximately (840-sf, 0.02-acres) and is located offsite to the north and adjacent to Eddy Street (Photo 3). Wetland A has both slope and depressional hydrogeomorphic (HGM) classifications (Brinson, 1993). Wetland A contains Palustrine forested Cowardin classification (Cowardin et al., 1979). Wetlands with both slope and depressional HGM classifications are rated as depressional wetlands by default according to the Washington State Wetland Rating System for Western Washington (2014 update) by Ecology. Vegetation identified within Wetland A includes slough sedge (Carex obnupta), creeping buttercup (Ranunculus repens), salmonberry (Rubus spectabilis), Pacific crabapple (Malus fusca), Pacific willow (Salix lasiandra), and Himalayan blackberry (Rubus bifrons). No soil test pits were able to be obtained due to its offsite location; however, a dark surface soils and a Sparsely Vegetated Concave Surface, wetland hydrology indicator B8, was observed from Eddy Street during the Site evaluation. Wetland A scored 6 points for improving water quality functions, 5 points for hydrologic functions, and 4 points for habitat functions through the 2014 Wetland Rating Form (Attachment 2). These scores total 15 points and qualify Wetland A as a Category IV wetland. In the City of Port Townsend, a Category IV wetland with a habitat score of 4 requires a standard 50-foot buffer, plus a 15-foot building setback measured from the edge of the critical area buffer per PTMC §19.05.110.G and PTMC §19.05.110.G.9. According to PTMC §19.05.110.D.5, the director may exempt buffers of wetlands that are less than 4,000 sf in area that are not associated with riparian areas or shorelines of the state and their associated buffers, are not part of a wetland mosaic, do not reach 6 or more points for their habitat score, and do not contain priority habitats or a priority area for priority species. Wetland A is an 840-sf wetland and is isolated from any other critical area or surface waters. Additionally, Wetland A has a habitat score of 4 and does not contain or have any adjacent priority habitats; it is also not recorded as habitat to any priority species. Though Wetland A’s standard buffer would not extend onsite according to Figure 1, Wetland A appears to qualify for exemptions from typical requirements to avoid impacts per PTMC §19.05.060.A. PROPOSED PROJECT The applicant proposes to construct a single-family residence, detached additional dwelling unit, and parking pad area onsite (Figure 2). No critical areas or associated buffers extend onsite; therefore, onsite development does not require mitigation and will not result in direct or indirect impacts to critical areas or their buffers. SUMMARY A critical areas evaluation was completed on the subject property (Jefferson County TPN: 95970- 1904) in the City of Port Townsend on 28 October 2025. One (1) wetland (Wetland A) was identified offsite, approximately 116 feet to the north of the Subject Property (Figure 1). No other critical areas were identified within the Study Area during the Site evaluation. Wetland A is a Category IV wetland with a habitat score of 4 which typically requires a 50-foot buffer and an additional 15-foot building setback measured from the edge of the critical area buffer. However, Wetland A appears to be exempt from wetland typical wetland buffer avoidance regulations according to PTMC §19.05.110.D.5. Regardless, Wetland A’s standard buffer does not extend onsite. The applicant proposes to construct a single-family residence, detached additional dwelling unit, and parking pad area onsite (Figure 2). This proposed development is situated outside of critical areas and their associated buffers. Therefore, this project will not result in direct or indirect impacts to critical areas or their buffers and does not require mitigation. We trust that the information presented here sufficiently describes and documents the critical areas on your property.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 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. 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 Wetland A Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Version 2, July 2023 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.

Priority Habitat and Species List. Olympia, Washington. This list was updated for consistency with guidance from WDFW. This question is independent of the land use between the wetland unit and the priority habitat. All vegetated wetlands are Priority Habitat but are not included in this list because they are addressed by this rating system Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha). Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and wildlife (full descriptions in WDFW PHS report). Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. Fresh Deepwater. Lands permanently flooded with freshwater, including environments where surface water is permanent and often deep, so that water, rather than air, is the principal medium within which the dominant organism lives. Substrate does not support emergent vegetation. Do not select if Instream habitat is also present, or if the entire Deepwater feature is included in the wetland unit being rated (such as pond with a vegetated fringe) Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock. Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report – see web link on previous page). Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species, forming a multilayered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha ) > 32 in (81 cm) dbh or > 200 years of age. Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; crown cover may be less than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old-growth; 80-200 years old west of the Cascade crest. Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 – see web link above). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft (6 m) long.

The wetland lies in a depression adjacent to marine waters that is wholly or partially separated from marine waters by sandbanks, gravel banks, shingle, or, less frequently, rocks The lagoon in which the wetland is located contains ponded water that is saline or brackish (> 0.5 ppt) during most of the year in at least a portion of the lagoon (needs to be measured near the bottom) Yes – Go to SC 5.1 No = Not a wetland in a coastal lagoon SC 5.1. Does the wetland meet all of the following three conditions? The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing), and has less than 20% cover of aggressive, opportunistic plant species (see list of species on p. 100). At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or unmowed grassland. The wetland is larger than 1/10 ac (4350 ft2) Yes = Category I No = Category II No SC 6.0. Interdunal Wetlands Is the wetland west of the 1889 line (also called the Western Boundary of Upland Ownership or WBUO)? If you answer yes you will still need to rate the wetland based on its habitat functions. In practical terms that means the following geographic areas: Long Beach Peninsula: Lands west of SR 103 Grayland-Westport: Lands west of SR 105 Ocean Shores-Copalis: Lands west of SR 115 and SR 109 Yes – Go to SC 6.1 No = not an interdunal wetland for rating SC 6.1. Is the wetland 1 ac or larger and scores an 8 or 9 for the habitat functions on the form (rates H,H,H or H,H,M for the three aspects of function)? Yes = Category I No – Go to SC 6.2 SC 6.2. Is the wetland 1 ac or larger, or is it in a mosaic of wetlands that is 1 ac or larger? Yes = Category II No – Go to SC 6.3 SC 6.3. Is the unit between 0.1 and 1 ac, or is it in a mosaic of wetlands that is between 0.1 and 1 ac? Yes = Category III No = Category IV No Category of wetland based on Special Characteristics If you answered No for all types, enter “Not Applicable” on Summary Form N/A Wetland A Wetland Rating System for Western WA: 2014 Update 13 Rating Form – Version 2, July 2023 This page left blank intentionally Contributing Basin Esri, NASA, NGA, USGS, FEMASources: Esri, HERE, Garmin, Intermap, increment P Corp., GEBCO, USGS,FAO, NPS, NRCAN, GeoBase, IGN, Kadaster NL, Ordnance Survey, Esri November 24, 2025 0 0.2 0.40.1 Miles K Subbasins (12 digit HUCs) HUC boundary City of Port Townsend, Vantor UNDISTURBED AREAS (52.83%) MODERATE INTENSITY LAND USE (26.01%) HIGH INTENSITY LAND USE (21.16%)m EASTSIDE ENVRIONMENTAL PROS, INC. 18500 156th Ave NE, Suite 203 Woodinville, Washington 98072 Bus (425) 949-6659 FIGURE # C MAP OF HABITAT WITHIN 1-KILOMETER NEAT DELINEATION P O R T T O W N S E N D, WASHINGTON SCALE NTS DRAWN BY: AS FIGURE C Date: 10/28/2025 SITE PLAN LEGEND 2.48 mi 303d Island County, WA State Parks GIS, Esri, TomTom, Garmin, SafeGraph,GeoTechnologies, Inc, METI/NASA, USGS, Bureau of Land Management,EPA, NPS, USDA, USFWS November 24, 2025 0 1 20.5 Miles K Assessed Water/Sediment WaterCategory 5 - 303d Category 4CCategory 4BCategory 4ACategory 2Category 1 SedimentCategory 5 - 303d Category 4CCategory 4BCategory 4ACategory 2Category 1 Water Quality StandardsAll Standards ATTACHMENT 3 Corps Antecedent Precipitation Tool. 28 October 2025 This normal precipitation analysis follows the methodology described by Sprecher and Warne (2000).
