,Download In State Plane Projection Here.,Boundaries of designated high quality ADID wetlands established as a result of a formal process under the direction of the U.S. Environmental Protection Agency. Part 404(b)(1) of the Clean Water Act authorizes the USEPA and the US Army Corps of Engineers to identify in advance of specific permit requests aquatic sites which will be considered as areas generally unsuitable for disposal of dredged or fill material. This process is called an Advanced Identification or ADID. Under the ADID process identification of an area as generally unsuitable for fill does not prohibit applications for permits to fill in these areas. Therefore the ADID designation of unsuitability is advisory not regulatory.,An ADID designation lets a potential applicant know in advance that a proposal to fill such a site is not likely to be consistent with the 404(b)(1) guidelines, and the USEPA will probably request permit denial.,ADID wetland information is also useful in watershed planning, land use planning, public land acquisition programs, natural resource studies and other purposes.,The wetland selection criteria and methodology are documented in the publication entitled "Advanced Identification (ADID) Study, Lake County, Illinois. Final Report, November 1992" which is included in this download.,Boundaries were delineated by the ADID project team on orthophotograph background with an intended usage scale of 1" = 400', a scale ratio of 1:4800.,
