Box 402 Chimacum, WA 98265 Karyn Williams Wetland Report and Updated Buffer Rating 409 Center Road Chimacum, WA Parcel # 90L I42 001 Introduction Olympic Wetland Resources, LLC has been authorized by Karyn Williams to determine if there are changes from a wetland delineation conducted in 2007 (Karyn Williams, Wetland Delineation and Analysis Report, Parcel # 901 142 001, August 2007). At that time a delineated edge was established, a Category III wetland rated with 5O-foot buffers, and a building envelope was defined. Since the original delineation the Department of Ecology (DOE) has updated rating standards (2014), therefore new buffer widths will now apply to all construction projects. A current rating form is included with this report. The field work for this assessment at 409 Center Road Chimacum, Washington was conducted on February 28,2019. A single family residence, a barn, and outbuildings have been constructed within the established building envelope and outside of 50 footwetland buffers established in 2007. A 30'X 5O'garage is proposed within this same building envelope. This agricultural pasture land has been developed to a successful working farm known as Red Dog Farm. Description of Site . Legal Description: Parcel#901 142 001, Section 14 Township 29N Range 1W . Location: 409 Center Road, Chimacum WA, Jefferson County WA (approximately Yz mile south of the Highway 19 and Center Road four way intersection) o Soils: Se Semiahmoo muck, Th Tisch silt loam, Bk Belfast silt loam, small north east corner is SaB San Juan gravelly sandy loam (a11 listed as a hydric soil, Jefferson County Hydric Soil List 1 l9l except SaB), Slopes: 0 to 8 percent This 23 acre site is described in the original 2007 Wetland Delineation report and includes soil pit details, hydrology, and vegetation identified on the parcel. This report included updates in the current codes and ratings. Williams Wetland Assessment and Rating Report File 2019-0229 Olympic Wetland Resources, LLC March 2019 The following figures can be found at the end of this report: Figure 1, Site Location and Aerial ffi&p, Figure 2, Original Delineation 2007,2019 Site Plan with updated Buffers, Figure 3, Photographs, Figure 4,1 KM Polygon to support DOE rating. Methodology Fieldwork to determine the actual wetland boundaries was conducted according to the methodology outlined in the Washington State Wetland Identification and Delineation Manual (Department of Ecology March 1997) and 18.22 Critical Areas (2009), 18.22.2270, FWHCAs 18.22.440 HMP. All wetlands within Jefferson County are subject to requirements outlined in the Jefferson County Unified Development Code (UDC) dated March 2009 with updates. Wetland Assessment and Rating Findings The parcel consists of agricultural land in the valley between Chimacum Creek to the west and Center Road to the east. Chimacum Creek is now rated as a Type 66F" fish bearing stream with 150' buffers; all construction is proposed outside creek buffers. The assessment in February 28,2019 followed a major snow storm and surface water was present in the low areas outside the mapped building envelope. The 2007 delineated wetland edge has NOT changed; it is defined by a distinct drop in topography (approximately 4 feet), hydrology, and the presence of wetland vegetation. A hedge of native wetland shrubs was planted between the wetland edge and the building envelope. Wetland Analysis Results During the original rating the wetland classified as Category III with 50 foot buffers. The rationale behind this categorization is that the wetland is has little species diversity,habitat value, and is surrounded by agricultural land. The new assessment still indicates the wetland rating as Category III ( 16 points with 4 points for Habitat). There is a connection via a man-made ditch to Chimacum Creek, the Creek is also confined to a distinct channel. Recent revegetation along the buffer edges do not change this categorization. In Jefferson County, the updated buffer width for a delineated Category III wetland is 60 feet due to the low habitat quality of this agricultural wetland. All buffers are measured perpendicular from the delineated edge (Jefferson County Unified Development Code, Jan. I ,2001, 3-30 Buffers Table 3-4). The proposed garage will be constructed outside all buffers and within the istinq buildi 1oexmg enve ategory III Wetlands Moderate Level of Function for Habitat (Score for Habitat 5 - 7 Points) Low -75 feet Moderate - 110 feet High - 150 feet Reserved. Score for Habitat 3 - 4 Points Low - 40 feet Moderate - 60 feet High - 80 feet Reserved. Williams Wetland Assessment and Rating Report File 2019-0229 Olympic Wetland Resources, LLC March 20192 Summary A Category III wetland was delineated and rated in August2007 and required 50 foot buffers. Currently there is a single family residence and farm building outside of those buffers in the established building envelope. The goal for this project is to build a30'X 50' unheated garage within that same building envelope. This report confirms findings from the 2007 wetland delineation. The wetland edge still coffesponds with a distinct swale connected by a man made ditch to Chimacum Creek. A11 data was reexamined and confirmed during field findings on Febru ary 28th 2019. According to the updated DOE rating form the wetland still qualiff as Category III due to lack of diversity with the exception of recent voluntary plantings of native shrubs. Buffers will now be 60 feet measured from the wetland edge; the proposed garage is outside all buffers. Final authority over this wetland determination will be Jefferson County Department of Community Development. Jurisdictional authority over wetlands rests with the local, state and federal agencies. All information in this report should be reviewed by the appropriate regulatory agencies prior to approval. If there are further questions or planning requirements, please do not hesitate to call.
