4 Model Outputs The inputs provide the basis for a series of outputs for each of the nine assessment fields. The model's programming encompasses a series of calculations and formulas that compute the outputs. As previously indicated,these are termed model calculations. To illustrate, for the physical and site analyses, the user enters the number and types of residential units as well as the site's total acreage and developable acreage. With these inputs, the model calculates a series of outputs. For instance, the gross residential density is equal to the number of units divided by the site's developable area. Other land use factors such as the floor/area ratio are similarly calculated by the application of appropriate formulas. The project pro forma, entered under the physical and site analysis, is the basis for many other calculations. By applying the demographic multipliers - the average number of people and school-age children residing in different type and size housing units - to the project profile, the model determines the development's projected population. Applying the model factors for per capita water use, sewage system use, and solid waste generation to the development population yields an estimate of environmental effects. Applying local per capita and per pupil expenditures to the development generated population produces the public service costs associated with growth. By matching expenditures to the revenues generated by development, the model calculates the net fiscal impact. In short,the model consists of a series of input data and output information. The inputs are based on readily available user information and factors already embodied in the model. The outputs comprise a series of linked findings across several dimensions of impact assessment as listed and described below. Model Components Administrative/Legal. The administrative/legal component of the model is largely descriptive. It provides tracking type data on the development and signals the level of scrutiny that the development must undergo. Physical/Land Planning. The second component is more analytic than the first and involves the physical setting of development impeding conditions en route to a determination of land-holding capacity. It is also descriptive in that the development's gross housing unit numbers and thousands of square feet of nonresidential space are initially displayed. Market Impact. The market assessment deals with the extent to which the development's land use components are interrelated with the regional market demand for such components. It compares the features offered by the development to the demand for the same. Environmental Impact. The environmental impact component scans a number of significant environmental factors, including impacts of utility systems, the level of development in sensitive areas,and the framework for environmental reviewing.
