UPLAN Urban Growth Model (UPLAN)
The UPLAN Urban Growth Model (UPLAN) provides a land use evaluation and change analysis based on general land-use plans, population and employment projections, characteristics of housing, and other user-defined conditions. It is an integrated package of user-specified attractions that enable users to: 1) conduct a land suitability analysis, and 2) project future land use demand. UPLAN helps communities create alternative visions for their area's future by mapping alternative development patterns determined by local land development policies. Some of the policies and decisions UPLAN addresses include establishing various criteria to "weight" the suitability of different locations for a particular land use, incorporating various land use planning and zoning considerations and other allocation scenarios, and defining various growth scenarios. The model can also be used to determine various environmental and social constraints to growth by modifying the criteria and the associated weights.|
The UPLAN model allows the user to develop specific parameters in the form of grids in which to model future land uses. The model allows the user to generate attraction grids, exclusion grids, general plan grids, and existing urban grids. Attractive grids are locations for future development (i.e., near to freeway ramps); exclusion grids, list areas where development should not occur (i.e. parks, waterways etc.); general plan grid is a composite grid of the general plan land use maps from the users region; and existing urban grid provides the current land use conditions. Each grid applies user-defined decision criteria (e.g., identifying and weighting grid factors), to derive study-area conditions. These decision criteria are applied to land use information stored in geographic information system (GIS) data files to create maps and reports showing where future development may occur.
