The Wisconsin Wetland Inventory(WWI)mapped the much of the Property as wetland(Figure 3), The objective of the wetland determination and delineation was to provide an estimate of the extent and spatial arrangement of wetlands at the Property. Most wetlands are considered waters of the U.S.and are therefore subject to regulation under the Clean Water Aot(CWA). Specifically,non-isolated wetlands are regulated under section 404 of the CWA and the jurisdictional regulatory authority lies with the United States Army Corps of Engineers(USACE). Additionally,the Wisconsin Department of Natural Resources(WDNR)has regulatory authority under Chapter 30 Wisconsin State Statutes and NR 103 Wisconsin Administrative Code. The Town of Westport and/or Dane County has additional regulatory authority through their Shoreland/Wetland Zoning Ordinance. NRC understands the requested services to include: I.
