In the course of thirty years, the pur- poses of comprehensive water resource planning had expanded fourfold, and one can assume that the col- lective skills and competence required from water resource planners had increased in some proportional measure. In terms of fundamental objectives, theories, and concepts, the field of environmental planning today is probably at the same level that water re- source planning was in 1933. Yet the commitment and expectations evidenced by the environmental pro- grams and policies in varying levels of government rival present goals of water resource development. Specific programs seem designed to either preserve, order, manipulate, or create aspects of the natural and artificial environment. The intent of each program is not difficult to identify. The more dif- ficult task is to attempt to generalize these in- tents, forming objectives that can bring together isolated programs in a comprehensive planning framework. i"':...,,.."ft.. ~~I,;~. ~.- - Objectives of Environmental Planning The objectives found in the specialized lit- eratureof individual programs when reduced to the smallest number of common denominators. are (as shown in Figure 1) physical and mental health, sensory and participatory pleasure, and economic value. Programs are justified in terms of the prevention of sickness (as is pollution control) and the provision of pleasure--either through aesthetic stimulation of the senses (for example, highway beautification) or through providing op- portunities for participating in pleasurable, en- vironmentally oriented activities (for example, outdoor recreation). Economic value as a goal may take the form of preserving present values (for example, reducing corrosion-inducing pollutants in the atmosphere) or enhancement (for example, in- creasing the value of real property through archi- tecturalcontrol). If these are the irreducible objectives of-environmental planning, then the centra~ obstacle to developing more comprehensive planning may be the lack of a common currency with which to mutually relate these objectives. In any event, a model"\>fcomprehensive planning will not spring easily from the matrix of single~purpose activities that\is presently ingrained in our public life. 69 70 REGIONAL PLANNING: CHALLENGE AND PROSPECTS COMPREHENSIVE ENVIRONMENTAL PLANNING 71 Enclosed Space, a Model of Comprehensive Environmental Planning THE WHY AND HOW OF ENVIRONMENTAL PLANNING: THE INVESTMENT DECISION MODEL However, a model does readily exist on a much reduced scale, and one needs but to look around the The investment decision model provides for the room, wherein almost all aspects of the physical statement of a single or multiple objective with a environment have been manipulated and organized. suitable set of constraints.
