associated with each. The rationale for shifting the focus of the PB /EDC Work Group,.to these factors is explained in greater detail below. Performance standards. one objective contained in the initial agreement between the Planning Board and Economic Development Commission was the identification of performance standards and project size thresholds with which to control the intensity and thus the impact of land development. Traditionally, intensity has been controlled through the use of standards that regulate the bulk of buildings. Examples of such standards include building coverage, floor area, landscape surface, and impervious surface ratios. These standards in combination with building height limitations were the principal means of controlling bulk. Rather than limit - itself to consideration of these traditional standards, the PB /EDC Work Group decided to evaluate additional ways of controlling land use intensity. Among the techniques considered by the PB /EDC Work Group were three new standards promoted by performance zoning advocates. These standards included building volume, landscape volume, and site volume ratios, and introduced not only consideration of building height but the size of plant materials and vehicles. To help the PB /EDC Work Group understand the application of the standards, the staff suggested that three businesses be selected, representing each of the nonresidential land use categories identified in the target area analysis. The staff would then conduct a detailed analysis of each site to illustrate the relationship between development character and intensity standards. Initially, 18 sites were selected for evaluation by the PB /EDC Work Group. An additional site, a bank, has since been added to the list of "service" establishments. Each evaluation includes the preparation of a site plan rendering showing the location of buildings and landscaping, parking and loading areas, and streets and access drives. Photographs have also been taken of each site so that the PB /EDC Work Group can relate what is "on the ground" with the rendering (see Attachment 5). Related to the site analysis work, a spreadsheet template was developed to calculate land use intensity ratios for each site. The template was designed to enable calculations for single or multiple uses and is being expanded to permit calculation of other impacts, including traffic, solid waste, water consumption, sewage disposal, etc. An example of the template's use in deriving calculations for Parker - Hannifin is provided in Attachment 6. Summary sheets comparing site, land use intensity, and landscape characteristics of businesses evaluated to date are provided as Attachments 7, 8, and 9. 1992 Work_ objectives All of the work completed by the PB /EDC Work Group has led to the formulation of a more definitive goal; i.e., to develop an
