Abstract
 Floodplain Delineation and Preparation of Enhanced DFIRM Maps Track: Water Resources Author(s): Alfredo Frauenfelder Henrico County, Virginia, has been working with FEMA to accomplish a comprehensive update to the locality's Floodplain Management Program. This included complete redelineation of the locality's Special Flood Hazard Areas and creation of Enhanced Digital Flood Insurance Rate Maps (E-DFIRMs). This locality is one of the first localities in the nation to develop E-DFIRMs. This GIS-based effort allows the determination of floodplain extent on a site-by-site basis including all related flood study documentation in the form of a GIS-enabled relational database management system (RDBMS). The new floodplain delineation provides the basis for updating the locality's Code of Ordinances in regard to the management of floodplain areas in the locality. This comprehensive approach gives detailed and accurate planimetric and topographic data as well as provide the legislative framework to protect life and property in the locality.
