Finally, multipliers, based on existin[ <br />demographic and public facility data, can be <br />used to derive impacts of bui[dout develop- <br />ment for each new residential unit or each <br />increment of commerdal or industrial sc~uare <br />footage. These multipliers can include <br />increases in projected future population, future <br />additional school students, future demand for <br />water supply or sewage treatment, as well as <br />potential tax revenue and service casts. <br /> <br />DATA AVA!LABILITY <br />An important consideration in plannin~ a build- <br />out analysis is the availability of data. In the <br />idea( case, the community will have di[itai ver- <br />sions of its zoning, existin~ and future land use, <br />reads and transit, wetlands and floodplains, <br />open space, orthophota[raphs, and recent <br />development maps. aa we[[ as natural hazard <br />areas, and parcel and tax assessment maps. [n <br /> <br />will be unavailable or out of date and wilt have <br />to be supplemented and updated. <br /> The availability of data can be a major <br />bud[et constraint. In order to realize economies <br />of scale, re[/onal plannin~ a§enc[es can coordi- <br /> <br /> providir[~.a standard, re~ionwide set of land-use <br /> <br />Zoning Practice web pages.

It takes the principles of these eartler <br />efforts at inte§rative, forward thinking into the <br />present era of geographic information systems <br />and computer-based analyses.
