A cooperative project to demonstrate the use of earth-science information in land-use planning was started by the U.S. Geological Survey and the Fairfax County, Virginia, Office of Comprehensive Planning in 1976. Environmental conditions related to planned-development housing in the Lehigh tract include unstable slopes, sand and gravel resources, flood-prone areas, vegetation, and artificial fill. Computer-composite mapping was used to analyze these conditions by combining maps of various land characteristics. This system may be used for review of development plans, long-range planning, and the production of “land capability” maps; it is particularly useful in single-site selection.
