American Recovery and Reinvestment Act 2009 Section 110 Compliance Report for the U.S. Army Corps of Engineers, Chicago District. Inventory of Electronically Scanned and Geo-Referenced Historic Maps and Aerials Pertaining to the Chicago District, Cook, DuPage, Lake, and Will Counties, Illinois; Lak

At the request of the U.S. Army Corps of Engineers, St. Louis District, John MiIner Associates, Inc. (JMA) conducted a National Historic Preservation Act Section 110 compliance investigation for the Chicago District. The work entailed preparation of an inventory of electronically scanned and geo-referenced historic maps and aerial photographs that could be used in planning projects undertaken by the district in support of its major missions: flood control, shoreline protection, navigation, environmental protection, and emergency management. A total of 3,501 historic maps, map sections, and aerial photographs were inventoried, electronically scanned, and geo-referenced to facilitate integration with the current level of GIS mapping used by the district. Another 182 aerial photographs were inventoried and electronically scanned, but not geo-referenced, due to district priorities and funding limitations. This ARRA funded Task Order employed 23 specialists.
