ecent aerial photo coverage of many areas. Soils maps at 1:7,500,000, 1:250,000, and 1:12,000 scale are available in digital format for some areas. Reports since 1957 contain engineering uses of soils mapped, parent materials, geologic origin, climate, physiographic setting, and profiles. Federal Emergency Management Agency Earthquake hazard National Earthquake Hazards Reduction Program, “Recommended Provisions for Seismic Regulations for New Buildings and Older Structures,” issued 1997, includes seismic maps. State Geologic Agencies Geologic maps and reports State and county geologic maps; mineral resource maps; special maps such as for swelling soils; bulletins and monographs; well logs; water resources, ground water studies List of maps and reports published annually, unpublished information by direct coordination with State geologist Defense Mapping Agency (DMA) Topographic maps Standard scales of 1:12,500, 1:50,000, 1:250,000, and 1:1,000,000 foreign and worldwide coverage, including photomaps Index of available maps from DMA American Association of Petroleum Geologists Geological highway map series Scale approximately 1 inch to 30 miles shows surface geology and includes generalized time and rock unit columns, physiographic map, tectonic map, geologic history summary, and sections Published as 12 regional maps, including Alaska and Hawaii Tennessee Valley Authority (TVA) Topographic maps, geologic maps and reports Standard 7.5-minute TVA-USGS topographic maps, project pool maps, large-scale topographic maps of reservoirs, geologic maps and reports in connection with construction projects Coordinate with TVA for available specific information. U.S. Department of Interior, Bureau of Reclamation Geologic maps and reports Maps and reports prepared during project planning and design studies Reports on completed projects can be obtained by interlibrary loan or from USAEWES.
