Morgan County, a part of Planning Region 8 and represented on the Hoosier Heartland Coordinating Commission, is in south-central Indiana about 25 miles southwest of Indianapolis, the core of a large and expanding urban-industrial complex. Much of the growth pressure imposed on the dominantly rural, agriculturally oriented county results from the ease of access afforded to Indianapolis by three major highways that radiate from the center of the capital city into the county. Other factors that contribute to growth pressure are the attractive wooded hills in the southern part of the county and geologic conditions that generally favor homesite development. Certain considerations must be made, however, to determine the type of development best suited for given areas and the limits that must be imposed on development. The development potential of an area is partly controlled by its geologic environment and available resources. The maps compiled for this report are designed to provide guidelines for the planner and the developer so that they may make the best use of the resources of the county while avoiding environmental hazards. To assist in achieving these ends, information based on geology, hydrology, and soils in presented here in special regard to mineral resource potential and sanitary landfill suitability, and availability of industrial minerals were compiled originally on a scale of 1 inch to 1 mile. They have been reduced in size for this report, but the large-scale maps may be consulted in the offices of the Morgan County Plan Commission and of the Indiana Geological Survey. The sanitary landfill and mineral resources maps are self explanatory. The map showing drift thickness can be used in several kinds of studies that lead to use-suitability maps.
