JURISDICTIONAL DETERMINATION OF WETLANDS
The identification and location of jurisdictional Waters of the United States (which includes wetlands) regulated by the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act of 1977, is physically determined through a process known as a jurisdictional determination (JD). The method of performing a JD employs a multi-parameter approach defined in Technical Report Y-87-1, Corps of Engineers Wetlands Delineation Manual, dated January 1987, and supplemental guidance. It generally requires positive evidence of hydrophytic vegetation, hydric soils, and wetlands hydrology for a determination that an area is a wetland. The JD process establishes a line that separates and identifies the COE-regulated wetland areas from non-wetland (upland) areas that are not regulated by the COE.
