Abstract
 Using GIS to Derive Base Flood Elevations for Building Permits Track: State and Local Government Author(s): Evan Brown, Brent Johnson The Planning & Development Services Business Center of Sarasota County, Florida processes applications for construction permits. A critical element of each permit application is the minimum buildable elevation to prevent structure flooding. Staff previously used various paper map sources to formulate estimates in their analysis of an application. Hydrodynamic models and spatial data were developed to enable staff to provide a more effective and efficient determination of the minimum buildable elevation. An application was created using Avenue in ArcView 3.x to analyze the data and provide staff with essential information about the permit application. The application relates information about the location of the applicant parcel and, most importantly, supplies staff with the essential minimum buildable elevation. The GIS application enhances productivity and provides documentation for the application determination. The application was recently re-written in ArcObjects for use in ArcGIS 8.x and is now being ported to ArcGIS 9.x.
