A mathematical goal programming model is described for the purpose of normative policy evaluation of environmental land use management on the Texas Gulf Coast. The model's three-level hierarchy, linking statewide, multicounty, and local models, allows the explicit consideration o f competing goals (policies) a t different spatial scales. Microlevel impacts of macrolevel environmental policy decisions, and vice versa, can be assessed.The purpose of this paper is t o describe a normative framework within which alternative policies of an environmental land-use character can be evaluated. For many years geographers, planners, economists, and sociologists have been struggling with various facets of this problem. The literature of urban planning provides a rich array of small scale (census tract) urban allocation models for projecting future distributions of residential population, retailing, and manufacturing [6, 9, 101. Regional economics and regional science have provided us with a series of larger scale regional development models that relate regional resources to regional economic structure [ 4 ] . Although useful and interesting in their own right, both approaches have important limitations. Boyce, Day, and McDonald [ I ] have noted the lack of sensitivity of urban allocation models to alternative policy formulations particularly in the area of transportation, while regional resource models have generally not reflected sensitivity to environmental parameters except
