The basin was field delineated(on-site)November 21,2006 using the principles of the <br /> 1987 Corps of Engineers Wetland Delineation Manual including adopted modifications, <br /> guidance letters and memorandum of agreement. The routine delineation method was <br /> generally used and dominant vegetation was evaluated by estimated area cover and the <br /> 50/20 rule. Wetlands were classified according to the methodologies in Wetland and <br /> Deepwater Habitats of the United States(FWS/OBS Publication 79/31; Cowardin et. al. <br /> 1979)and Wetlands of the United States (USFWS Circular 39; Shaw and Fredin 1971). <br /> The wetland boundaries and observation points were staked with pink metal flagging. <br /> The locations of the staked basins were surveyed by Demars-Gabriel Land Surveyors Inc. <br /> and incorporated into the site plans. <br /> Basin Characteristics <br /> Table 1.

The <br /> fringe wetland consisted of Reed Canary Grass, Common Cattails and Red Osier <br /> Dogwood. Saturated soils and standing water was observed near the surface. The adjacent <br /> uplands were marked by a distinet topographic and vegetation break consisting of <br /> Kentucky Blue Gra.ss, Common Dandelion, Canada Thistle and Black Seed Plantain. <br /> There is a remnant large White Oak that had faller�near the wetland boundary, <br /> Wetland Jurisdiction <br /> Clean Water Act. Section 404 <br /> The U.S. Army Corps of Engineers(COE)regulates dred�e and fill activities in <br /> navigable waters,wetlands adjacent, tributary, or with significant nexus to <br /> navigable waters and isolated wetlands important to interstate commerce. A 2001 <br /> Supreme Court ruling has limited the COE jurisdiction over isolated wetlands,but <br /> the COE has not yet finalized guidance for implementing this ruling under Section <br /> 404 of the Clean Water Act. In most cases, if the proposed impacts are less than <br /> 400 square feet,the COE does not require notification of the project. If proposed <br /> impacts are between 400 square feet and 2.0 acres,the COE requires notification <br /> and approval (letter of permission)prior to beginning the project. If the wetland <br /> impacts occur in or adjacent to "special waters"andlor exceed 10,000 square feet, <br /> the COE review will include a 30-day public/interagency notice. If the proposed <br /> impacts exceed the WCA deminimus limits (see below),the COE will require <br />
