Wetland Delineation Report 1 September 27, 2021 INTRODUCTION Ecological Land Services, Inc. (ELS) was contracted by Andrew Vodder to conduct a critical areas reconnaissance to determine presence of streams and/or wetlands for the property located at 5662 Center Road, Jefferson County Tax Parcel Number 801091011, in Chimacum, Washington. This property is located in a portion of Section 9, Township 28 North, Range 1 West of the Willamette Meridian (Figure 1). This report summarizes findings of the wetland according to the Jefferson County Code (JCC), Chapter 18.22 Article VII Wetlands. METHODOLOGY The wetland determination followed the Routine Determination Method in the Western Mountains, Valleys, and Coast Region according to the U.S. Army Corps of Engineers, Wetland Delineation Manual (Environmental Laboratory 1987), and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys and Coast Region (Version 2.0) (U.S. Army Engineer Research and Development Center 2010). The Routine Determination Method examines three parameters—vegetation, soils, and hydrology—to determine if wetlands exist in a given area. Hydrology is critical in determining what is wetland but is often difficult to assess because hydrologic conditions can change periodically (hourly, daily, or seasonally). Consequently, it is necessary to determine if hydrophytic vegetation and hydric soils are present, which would indicate that water is present for long enough duration to support a wetland plant community. By definition, wetlands are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands are regulated as “Waters of the United States” by the U.S. Army Corps of Engineers (USACE), as “Waters of the State” by the Washington Department of Ecology (DOE), and locally by Jefferson County. To delineate the wetland boundaries on the property, ELS biologists collected data on vegetation, hydrology, and soils. The delineation site visit was conducted on July 8, 2021 during which one wetland was identified and delineated. The wetland boundary was delineated using consecutively numbered fluorescent flags labeled “WETLAND DELINEATION.” The wetland boundary was determined through breaks in topography, changes in vegetation, and evidence of wetland hydrology. Vegetation, hydrology, and soil data was collected at two test plots to verify the wetland boundary (Appendix A). The wetland boundary was mapped using a handheld Global Positioning System (GPS) unit to show the boundary on the site map (Figure 2). PROPERTY DESCRIPTION This 20.29-acre rectangular shaped property is located on the west side of Center Road north of Highway 104 (Figure 1). The property is undeveloped (Figure 2). The western three quarters of the property is composed of an open field with a fish bearing stream separating it from the forested eastern portion of the property. The eastern quarter slopes quickly down to the west toward the wetland and stream. The portion of the property west of the stream slopes gently down to the east creating the depression in which the wetland resides. The property is currently adjacent to similarly sized properties (some of which contain single family homes) and undeveloped Pope and Talbot logging properties. Vodder-Center Road Ecological Land Services, Inc. Wetland Delineation Report 2 September 27, 2021 VEGETATION The onsite portion of the wetland is composed of an emergent and forested community. The emergent community was dominated by reed canary grass (Phalaris arundinacea, FACW). The forested community was dominated by red alder (Alnus rubra, FAC), salmonberry (Rubus spectabilis, FAC), and vine maple (Acer circinatum, FAC). The herbaceous layer was dominated by false lily of the valley (Maianthemum dilatatum, FAC) with an occurrence of skunk cabbage (Lysichiton americanus, OBL) and water parsley (Oenanthe sarmentosa, OBL). The hydrophytic vegetation criterion is met at Test Plot 2 because of the dominance by FAC plant species. The upland forested area was dominated by Douglas fir (Pseudotsuga menziesii, FACU) and western red cedar (Thuja plicata, FAC), and red alder in the tree canopy (Photoplate 1). Low shrub cover was present and included salmonberry, Indian plum (Oemleria cerasiformis, FACU), and Oregon grape (Mahoina nervosa, FACU). The herbaceous layer was composed of youth on age (Tolmiea menziesii, FAC), stinging nettle (Urtica dioica, FAC), and sword fern (Polystichum munitum, FACU). In addition, there is a small area between the forested upland and the wetland dominated by a dense cover of salmonberry (Photoplate 1). The hydrophytic vegetation criterion is met at Test Plot 1 because of the dominance by FAC plant species. The dominant vegetation found onsite is recorded on the attached wetland determination data forms (Appendix A). The indicator status, following the common and scientific names, indicates how likely a species is to be found in wetlands. Listed from most likely to least likely to be found in wetlands, the indicator status categories are: ▪ OBL (obligate wetland) – Almost always occur in wetlands. ▪ FACW (facultative wetland) – Usually occur in wetlands but may occur in non-wetlands. ▪ FAC (facultative) – Occur in wetlands and non-wetlands. ▪ FACU (facultative upland) – Usually occur in non-wetlands but may occur in wetlands. ▪ UPL (obligate upland) – Almost never occur in wetlands. ▪ NI (no indicator) – Status not yet determined. SOILS As referenced on the Natural Resources Conservation Service website (NRCS 2020), Alderwood gravelly sandy loam, 15 to 30 percent slopes is mapped across the eastern third of this property with Semiahmoo muck (Se), Semiahmoo muck, moderately shallow variant (Sh), and Belfast silt loam, heavy variant (Bh) mapped throughout the western two-thirds of the property (Figure 3). Alderwood soils are moderately well-drained soils existing on glacially modified hills and ridges. These soils formed in glacial drift and outwash over dense glaciomarine deposits. Semiahmoo soils consist of very poorly drained organic soils that formed in well decomposed and disintegrated plant remains in glacial basins or old displaced stream and river channel ponded areas. A typical profile consists of a 10 to 15-inch-thick black muck surface layer and in most places two to four layers of muck and mucky peat are above the mineral soil material. Underlying mineral soils typically consist of loamy sand, sandy loam, sandy clay loam, sandy clay, and clay. Belfast soils are deep, moderately well-drained soils that formed in stratified alluvium. They typically exist on nearly level flood plains. Semiahmoo soils are classified as hydric because they are poorly drained Vodder-Center Road Ecological Land Services, Inc. Wetland Delineation Report 3 September 27, 2021 and composed of organic material. Alderwood and Belfast soils are not classified as hydric because they are moderately well-drained1 (NRCS 2016). The soil profile within Test Plot 1 revealed a single layer of loam to 20 inches deep. The soil had a dark brown (10YR 2/1) matrix color. The soil profile within Test Plot 2 was a black (Gley 1 2.5/N) muck to 19 inches below the surface. This soil profile met the hydric soil indicator Histosol (A1) because of the presence of organic material. The soil profile within Test Plot 1 did not meet any hydric soil indicators because there was no organic material, a depleted matrix, or redoximorphic features. HYDROLOGY The soil within the wetland was saturated to the surface (A3) and there was a high water table to 9 inches below the surface (A2) at the time of the site visit. A fish bearing stream flows south to north through the center of the property and provides hydrology to the portion of the wetland surrounding the stream. However, the majority of the wetland is within a depression where the main source of hydrology appears to be surface water runoff, groundwater, and direct precipitation. The wetland could possibly contribute to the hydrology of the stream. There was flowing water within the stream at the time of the site visit. The wetland hydrology criterion is met within the test plot location. There was no hydrology or evidence of wetland hydrology within the upland areas. CRITICAL AREAS INVENTORIES2 The U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI 2020) maps a large forested, emergent, and scrub-shrub wetland system on the western two-thirds of the property. It extends offsite to the north, west, and south. The stream is also mapped through the east end of the wetland (Figure 4). The mapping of the wetland was consistent with the findings of the ELS site visit. The Jefferson County Tax Parcel Viewer maps the wetland system and the Type F stream in the location mapped by the NWI (Figure 5). During the site visit, ELS biologists confirmed the presence of the onsite portion of the large wetland system and the stream as mapped based on data collected throughout the property. CONCLUSIONS WETLAND CATEGORIZATION The identified wetland is a Category II. It was categorized according to functions using the Washington State Wetlands Rating System for Western Washington, 2014 Update (Rating System) (Hruby 2014) (Appendix B). The hydrogeomorphic classification for the wetland is depressional, vegetation is forested and emergent communities, and the hydroperiods are saturated only and seasonally flooded with a permanently flowing stream. The overall wetland rating score was 20. 1 Areas mapped as hydric soils do not necessarily mean that an area is or is not a wetland—hydrology, hydrophytic vegetation, and hydric soils must all be present to classify an area as a wetland. 2 Critical area inventory maps are to be used with discretion because they are intended to gather general wetland information about a regional area and therefore are limited in accuracy for smaller areas due to their large scale. Vodder-Center Road Ecological Land Services, Inc. Wetland Delineation Report 4 September 27, 2021 The water quality function score is 8, the hydrologic function score is 5, and the habitat score is 7. The fish habitat stream within the wetland flows from the south to the north through the center of the property. WATER TYPING The JCC specifies the use of the Washington Department of Natural Resources (WDNR) water typing system (WDNR 2006) presented in Section 18.22.630 to determine the water type of streams. The Jefferson County public land records map classified the onsite site stream as a Type F water, which was confirmed during the field visit. It is a Type F water because the average bankfull width is greater than 2 feet and the gradient is less than 16 percent. CRITICAL AREA REGULATIONS The JCC Chapter 18.22.730 specifies wetland buffers based on wetland category, proposed land use intensity, and scores for habitat on the rating form. Because the wetland is a Category II system, the habitat score is moderate, and the proposed project is of moderate intensity land use, a buffer width of 110 feet is required from the edge of the wetland. The JCC Chapter 18.22.630 specifies buffers based on Department of Natural Resources (DNR) Water Typing System. The onsite stream is classified as a Type F (fish habitat) stream. Type F streams require 150 feet of buffer with an additional building and impervious surface setback of 15 feet. The stream buffer supersedes the wetland buffer, providing greater habitat protection to the critical areas. Therefore, the greater stream buffer will be used. SITE DEVELOPMENT PROPOSAL AND BUFFER REDUCTION PROCESS The JCC allows buffer reductions for projects that cannot be constructed outside the required wetland and/or stream buffer widths. Buffer reduction options include buffer averaging, which takes the amount of displaced buffer and increases the buffer in another location along the buffer. This creates an average buffer width that matches the regulated buffer width. A second option is a 25-percent reduction, which requires improvement of the buffer through enhancement of vegetation to provide equal or improved buffer function. No buffer reduction or averaging is proposed at this time. LIMITATIONS ELS bases this report’s determinations on standard scientific methodology and best professional judgment. In our opinion, local, state, and federal regulatory agencies should agree with our determinations. However, the information contained in this report should be considered preliminary and used at your own risk until it has been approved in writing by the appropriate regulatory agencies.

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. Wetland name or number: Wetland Rating System for Western WA: 2014 Update Rating Form – Effective January 1, 2015 4 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? Yes – Go to SC 3.3 No = Is not a bog SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30% cover of plant species listed in Table 4? Yes = Is a Category I bog No – Go to SC 3.4 NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the plant species in Table 4 are present, the wetland is a bog. SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the species (or combination of species) listed in Table 4 provide more than 30% of the cover under the canopy?
