The Indiana Floodplain Information Portal Launch INFIP, an interactive floodplain mapping tool, which includes address searching and eFARA, the Division of Water’s on-line floodplain analysis submittal tools. INFIP also now includes the “Best Available Data” layer, showing up to date floodplain mapping information.
FEMA Map Service Center View and download official FEMA floodplain mapping products, including Flood Insurance Rate Maps, Flood Insurance Studies, Letters of Map Change (LOMA, LOMR-F, LOMR) FIRM database information, and preliminary and historic mapping products.
The Indiana Hydrology and Hydraulics Model Library View and download previous hydrologic and hydraulic models developed for Flood Insurance Studies, Construction in a Floodway applications, Floodplain Analysis / Regulatory Assessment (FARA), and others.
The Indiana DNR HEC-RAS Geometric Data Tool This tool uses the State of Indiana’s LiDAR dataset, along with the National Hydrography Dataset, to create a Geometric Input file for HEC-RAS, the Corps of Engineers hydraulic modeling program.
Fluvial Erosion Hazards in Indiana The Fluvial Erosion Hazards portal features mapping of approximate areas of stream migration for communities to better manage river corridors. The setbacks vary based on the stream’s recent migration history (mobile or non-mobile).
Non Levee Embankments in Indiana The Non-Levee Embankment project is a joint effort between The Indiana Silver Jackets, The Polis Center, IMAGIS/Indy GIS, INDNR and SIU Geography. The purpose of the project is to identify non-levee embankments (NLE) utilizing LiDAR and geoprocessing techniques. NLE are elevated linear features adjacent to waterways and within the floodplain.
USGS Flood Inundation Mapper The Flood Inundation Mapper shows estimates of flood inundation areas based on USGS stream gage information. Areas are shown based on gage height, allowing users to view the approximate limits of a flood based on a reported gage reading.
