adopt the new maps and re~utations in <br />order to keep future development out of <br />harm's way. <br /> <br />MASSACHUSE'J'rs STATEWIDE gUILgOUT <br />ANALYSIS <br />The state of Massachusetts completed <br />dui[dour analyses for all of its 3SI commu- <br />nities in 2002, as part of th.e Community <br />Preservation Initiative of the [xecutfve <br />Office of Environmental Affairs. Outputs of <br />the analyses included number of housing <br />units, population and number of school <br />children, square feet of commercial and <br />industrial space, §alEphs of water demand, <br />and miles of roads. These analyses were <br />presented to local decision makers to help <br />them evaluate potential impacts of future <br />devetopment and to create a receptive <br />environment for discussion of alternatives <br />such as zonin~ changes, open space pro- <br />tection, and regional cooperation. <br /> MassGIS--the state geographic infor- <br />mation agency--provided developed land- <br />use data, Analyses were conducted by <br />regional planning agencies and consult- <br />ants. Undeveloped land in each zoning <br />district was identified through interpreta- <br />tion of orthophotographs (photographs <br />prepared from perspective photographs <br />by removing distortions and displace- <br />ments of points caused by tilt, relief, and <br />perspective), ignodng parcel boundaries. <br />Using oveday and spreadsheet tools, stan- <br />dard formulas were applied to generate <br />yields of future residential units and com- <br />mercial/industrial areas. The state pro- <br />vided a buJtdout analysis methodology <br />and scope of services for contractors. <br />Because the Office of Environmental <br />Affairs contracted in bulk for the buildout <br />analyses for the entire state, there were <br />significant economies of scale and each <br />buildout map series cost only $7,000 per <br />community. <br /> <br /> By using a consistent methodology <br /> and set of land-use categories, the buildout <br /> analysis maps could be a[~re§ated across <br /> regions, The Office of Environmental Affairs <br /> held meetin§s in five high-growth regions to <br /> show composite regional dui[clout maps and <br /> to facilitate discussions of coordinating <br /> regional growth manai)ement efforts. <br /> In addition to community orthopho- <br /> <br /> <br />
