The foundation of project environmental impact assessments and evaluations is a determination of the presence or absence of environmental regulatory agency jurisdiction, and if present, the geographic extent of this jurisdiction within the project site. HBG’s scientists delineate wetlands and other aquatic resources to determine the presence or absence of jurisdictional waters subject to US Army Corps of Engineers (Corps), state, and local jurisdiction. A jurisdictional delineation provides essential knowledge the project developer uses to develop permitting strategies and determine project costs, timeframes, and, ultimately, project feasibility.
HBG president Terry Huffman developed the Corps/US EPA wetlands definition and the technical criteria for the three-parameter methodology used today for determining wetland boundaries while he was the Chief Wetland Scientist for the Corps.
Jurisdictional delineation methods are also used to identify areas with hydrologic constraints where limited-to-no site-specific hydrology data are available to predict the location of, for example, wave erosion hazards or seasonal high groundwater, ponding, and/or flooding.
