HomeMy WebLinkAbout901273004 Camp Beausite Lake Beausite Wetland RatingOlympic Wetland Resources, Inc. Dixie Llewellin, Principal Biologist rating form for Camp Beausite Northwest. The project includes the addition of two new bunkhouses for the campers. This update is based on site visits which re-examined wetland boundaries along Beausite Lake in 2014 and 2015 (Camp Beausite Northwest Habitat Management Plan, September 2014 and Camp Beausite Northwest Phase II Wetland Delineation November 2015). During these field visits the wetland edge of Beausite Lake was in conceft with previous information found during the Wetland Delineation in 1996 Q.{orthwest Kiwanis Camp, Beausite Delineation, July 1995). Original stakes were still present and reflagged in 2014. Updated Wetland Rating Form The entire wetland around the perimeter of Beausite Lake could not be examined. Areas closely examined include shoreline trails along the eastem edge of the lake, the outlet ditch, and high intensity land use locations which border the lake. These include the lodge, camp facilities, and caretaker's cabin. Additional data was acquired by examining National Wetland Inventory maps, soil surveys, critical areas maps, and aerial photographs (included on Sheet #1). The current approach to wetland rating now includes the evaluation of wetlands fbr improving water quality, hydrologic, and habitat functions. Key elements include landscape settings, the basins and sub-basin contribution for prevention of downstream flooding, and potential for water filtration. Habitat function is assessed according to structural layers, interspersion of habitats" and surrounding natural buffers. Wetlands associated with Beausite Lake were rated as to their value to society. Land uses were determined within one kilometer of the wetland edge to calculate areas of impact (included in Sheet #2). Using the Washington State Wetland Rating System, effective January 2015 this wetland rates as a Category II wetland. It received 6 points for Improving Water Quality, 6 points for Hydrologic Functions, and 8 points for Habitat Functions (total of 20 points). Camp Beausite Northwest, Wetland Rating Form Report File #2016-1221 December 2016 Buffer Requirements This commercial development is considered high intensity land use according the Jefferson County UDC table (Table 18.22.330(3). Buffers for this high habitat wetland will be 300 feet measured perpendicular from the delineated wetland edge. According to the site plan submitted by Simon Little the two bunkhouses are 333' and 429' respectively from the wetland edge. Limitations The final authority for the approval of this wetland ratingwill be Jefferson County Department of Community Development. Jurisdictional authority over wetlands and shorelines rests with the local, state and federal agencies. If there are further questions or planning requirements for this phase or future phases of this development, please do not hesitate to call.
