Applying Environmental Geology Concepts To Urban Development Planning An Example: Tippecanoe County, Indiana

Planning for urban development in many locations is based largely on 0.10 factors, 1) soil conditions and 2) socio-political aspects of the region. A more widely based approach is necessary, however, if a complete and functional plan is to be obtained. Under this unified approach, the overall field of earth science is included in the planning process. As considered here, the earth sciences comprise a large segment of the natural sciences; that is, geology, pedology, geomorphology, reengineering geology and ground water hydrology. A number of shortcomings can develop when using the restrictive, two-factor approach for urban development planning. These deficiencies are discussed in the paper. The specific considerations for each earth science area are examined and land use considerations for various urban requirements reviewed in light of these specialties. To illustrate the potential of the unified or earth science approach, Tippecanoe County, Indiana is presented as an example. The current area planning system for Tippecanoe County is examined to determine how well it compares with the unified approach and some of the shortcomings of the current plans are discussed.
