Soils, ve etation, and h drolo g Y gY were evaluated to verify the presence of wetlands and determine wetland classifcations. According to the Department of Ecology rating system this wetland is a high quality Class III wetland. It is small in size, less than 1/4 acre, but is very high in plant species diversity, structural layers, and has a high quality undisturbed buffer. Class III wetland receive 50 foot buffers if delineated and 75 feet buffers if not delineated (UDC Section 3 Tables 3-3 and 3-4). John Heal of Bionomics identified this small seasonal wetland adjacent to the access driveway in December 1990. During this assessment hydric soils (lOYR 2/1 overlying a clay layer of 10YR 5/1 with extensive streaking and mottling), hydrophytic vegetation (sedges, water parsley), and moist soils were identified. This wetland averages about 118 feet X 30 feet (3,540 square feet) and is confined to the low-lying areas. All wetlands over 2,500 square feet are regulated b Jefferson Count UDC 3.6.9 Y y( a. l ). The cleared area for the home site is slightly upslope and 120 feet from the wetland edge. The enclosed map indicates the general vicinity of the wetland location; this map does not re resent a P formal wetland delineation.
