ABSTRACT
The challenge to planners is to determine what effects a given landuse plan will have upon the sand and gravel industry, and to establish alternative actions or adjustments that will allow the plan to be implemented while maintaining and stimulating a healthy sand and gravel business. The technique allows them to test the effects of alternative landuse options for a more satisfying time—space development of sand and gravel resources. The problem of planning sound landuse allocations while maintaining healthy business conditions is acute because of the great demand that exists for construction aggregate. Marketing dynamics respond to a constantly changing set of demand pressures and transportation constraints that, through time, yield mappable geographic patterns. Central-place theory was derived from the empirical relationships of marketplaces that shift geographically in response to changes in location and character of demand.
