OF COMMUNITY DEVELOPMENT Description of Site · Description: Parcel # 970-800-606 970-800-511 970-800-403 S-T-R 33-29N-01E Mats Mats Beach, Port Ludlow, WA · Location: At the end of Prospect Road off of Bayshore Drive from Oak Bay Road The property is adjacent to and slopes gently towards Mats Mats Bay, near Port Ludlow, WA. It is comprised of numerous mature trees, both native and planted, and open grassy areas. A house and several out-buildings, including a trailer, are on the site. Local soils consist of a top layer over the glacial till. The hard till layer prevents surface water filtration, which often leads to drainage problems. The property is divided by several drainage channels that direct water towards a small pond before entering Mats Mats Bay. Introduction At the request of Christopher Carson, authorized representative for Dave Fraser and Jo Ann Alber, Dixie Llewellin of Olympic Wetland Resources, Inc. conducted a wetland reconnaissance Fraser Wetland Report 2000-0096 ] Olympic Wetland Resources, Inc. 7/00 on July 25, 2000, of the Mats Mats Beach property. The purpose of this survey was to examine wetlands that are shown on the critical areas maps of Jefferson County dated February 21, 1995 (Appendix Map # 1). Findings from this report will fulfill the requirements for Conditions of Approval, Jefferson County Interim Critical Areas Ordinance. Wetlands outlined on the Jefferson Critical Areas Maps are primarily along the shoreline. This is consistent with the wetlands mapped on the National Wetland Inventory Map as category E2 AB/US N (Estuarine, Intertidal, Aquatic Bed over Unconsolidated Shore which is regularly flooded). Findings confirm the wetlands as mapped and the saltwater edge is quite distinct from the upland. In addition to the obvious estuarine wetland, a small Category III non-intertidal wetland was identified. This wetland measured 5,330 square feet. This is less than the required 10,000 square feet and is therefore not regulated by Jefferson County Critical Areas Ordinance (Section 6 Wetlands 6.302 Designation). A complete wetland delineation is not required for this project. Methodology The following maps were consuked for this project: · Jefferson Critical Areas Map Wetlands (1995) · Soil Survey of Jefferson County (U.S. Soil Conservation Service 1975) · National Wetland Inventory Map 2001 jEFFERSON COUNTY DEPT. OF COMMUNITY DEVELOPMENT Fieldwork to determine the actual wetland boundaries was conducted according to the methodology outlined in the Washin~on State Wetland Identification and Delineation Manual (Department of Ecology #96-94). Washington Administrative Code requires that all wetlands within the State of Washington be delineated using this manual. The methodology outlined in the Washin~on State Wetland Identification and Delineation Manual requires examination of the three parameters for a positive wetland determination: hydric soils, hydrophytic vegetation, and hydrology. For an area to qualify as a jurisdictional wetland it must have a positive indicator from all three parameters. All wetlands identified using this methodology may be federally regulated, regardless of size. A hydric soil is a soil that forms under conditions of saturation, flooding, or ponding which last long enough during the growing season to result in an anaerobic upper layer. Hydric soils favor the growth and regeneration ofhydrophytic vegetation. The indicators for this type of soil include low chroma, mottles, gleying, and high organic content within the upper 32 inches of the soil profile. Holes were dug on the site and soil colors (including value and chroma) were recorded in the top 16 inches. Soil colors were analyzed using the Munsell Color Charts (1992). Fraser Wetland Report 2000-0096 2 Olympic Wetland Resources, Inc. 7/00 MAR - 1 2001 JEFFERSON COUNTY Vegetation DEPT. OF COMMUNITY DEVELOPMENT Wetland plant species must constitute greater than 50% of the total vegetation present to meet the qualification as a site dominated by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover within a 30-foot radius for trees, a 1 O-foot radius for shrubs, and a 6- foot radius for the herbaceous layer at each data point. Commonly occurring plant species have been ' rated by the United States Fish and Wildlife (USFW), National List of Plant Species that occur in Wetlands: Northwest (Region 9), as to their frequency of occurrence in wetlands and non-wetlands. During the fieldwork, each species was recorded and given a rating based on indicator status. Hydrology Wetland.hydrology is defined in the Washin~on State Wetland Identification and Delineation Manual as "areas that are periodically inundated or have soils saturated to the surface at some time during the growing season". Areas must have seasonally inundated or saturated soil at least 12.5% of the growing season. Indicators of hydrology include visual observation of inundation or soil saturation, water- stained leaves, cracking of the soil surface, and/or sediment deposits. Positive signs of hydrology are often absent during the summer and fall months but can be inferred if there are positive indicators of hydric soil and hydrophytic vegetation. Wetland Edges Approximate wetland edges were determined by establishing a data point within the wetland, which contained positive indicators of all three ofthe wetland requirements:, soils, hydrology, and vegetation, and another data point outside the wetland, where neither wetland soils, hydrology, nor hydrophytic vegetation were present. Measurements were taken with a Chainman II hip chain. Classification Wetland categorization was determined using the WA State Department of Ecology (DOE) Wetland Rating System (publication//91-57 October 1991), which assigns a numerical value to any given wetland according to wetland size, quality of surrounding buffers, vegetation diversity, wetland types, and habitat value. Wetlands are rated as entire systems and quite often exceed project boundaries. Findings Shorelines are consistent as mapped and setback standards will apply to this project. All projects within 200 feet of the shoreline are subject to evaluation. Standards include a mandatory 30' setback from the saltwater edge with other qualifiers according to bluff height. Each project is reviewed on a case-by-case basis. This project will probably be exempt from some of the regulations since it falls within the footprint of the existing house and is over 30' from the shoreline (conversation with Josh Peters, July 28,2000 Jefferson County Department of Community Development, Shorelines). Locations of soil test pits and wetland data points are indicated on Map//2 in the Appendix. Hydrophytic vegetation such as sedges, rushes, and wetland grasses (Agrostis alba and Holcus lanatus) were found only on the eastern edge of the site and not near the existing house. Fraser Wetland Report 2000-0096 3 Olympic Wetland Resources, Inc. 7/00 Wetland soils, which are low chroma (10YR 3/2 and 5Y 4/2 with orange mottles) were found throughout the eastern edge of the site. Wetland plants exist thorough out the site but it is the wetland the soils that are the true indicators of the wetland edge. Wetlands extend downslope into the forested area (dominated by alders and hawthorns) near the shoreline. Water was not found in the test pits but during the dryer months (between July and November) hydrology can be assumed when there are both wetland plants and Wetland soils. Water only needs to be present 20 days of the growing season for an area to qualify as a wetland. The growing season is defined by the Jefferson County soil survey as March 12 to November 25 in or near Port Townsend. Hydrology must be present for 12.5% (20 days) of these 258 days. Drainage channels direct stormwater fi.om uphill properties to a man-made pond (water to depths of 16 inches), which lies near the forested area adjacent to the bay. This pond not only increases wildlife habitat potential but is also a beneficial landscape feature that retains and treat surface water prior to entering Mats Mats Bay. Other native species (besides cattails) could be introduced to increase plant diversity. The wetland classifies as a Class III wetland, approximately 41 by 130 feet (5,330 square feet). Class III wetlands are only regulated by the Jefferson County Critical Areas Ordinance if they are larger than 10,000 square feet (Section 6.302). DOE rating form is included the Appendix. Final authority over this wetland determination rests with Jefferson County Department of Community Development, Critical Areas staff and the Corps of Engineers.
