Are you SAFR not? A Flood Risk Identification GIS Web Mapping Application – UPDATE
Abstract
This talk will give an update on what has been happening with the Structures at Flood Risk (SAFR) web mapping application. Developed by the Illinois State Water Survey (ISWS) with support from the Illinois Department of Natural Resources/Office of Water Resources (IDNR/OWR) and U.S. Army Corps of Engineers (USACE), SAFR hosts data produced during structure specific flood risk assessments for multiple areas in Illinois. Data from surveys of said structures, combined with annual-chance exceedance depth grids for multiple events, are analyzed to estimate what losses would occur if these areas were to experience flooding. The SAFR web map allows community floodplain managers in the project areas to select individual structures and display or download the estimated flood losses, surveyed elevations, and flood depth data for use in aiding mitigation efforts.
