DELINEATIONS

WEC conducts jurisdictional delineation to confirm the presence or absence of streams, wetlands, and other waters of the U.S. on a project site. Our services include an initial in-house review of available information such as soil surveys, topographic maps, aerial photographs, and National Wetland Inventory maps. Potential jurisdictional areas are then investigated during a site visit to confirm their presence or absence, followed by a field delineation (i.e. flagged) for visual reference and for a subsequent metes-and-bounds survey using methodology described in the U.S. Army Corps of Engineers 1987 Wetland Delineation Manual. Typically, these boundaries are surveyed using our in-house Global Positioning System (GPS) to sub-meter accuracy. These digital survey data are placed on the client’s development plans and directly provided to the client to determine what level of permitting is required.
