Indiana Floodplain Information Portal

The Indiana Floodplain Information Portal (INFIP) is a mapping application developed by the DNR, Division of Water that provides floodplain information for public use. The portal displays floodplain information from both FEMA and DNR sources, including mapped floodplains and flood elevation points along waterways. In addition, the revised INFIP allows users to generate a Floodplain Analysis and Regulatory Assessment (FARA) by using the FARA Report Generator. A FARA is required for local floodplain permitting and FEMA Letter of Map Amendment applications in A zones.

  • A FARA is also required for regulatory determination when the upstream drainage area is greater than 1 square mile, for areas that are unmapped on the FIRM, or for areas known to be flood prone.
  • Base Flood Elevation (BFE) determinations are often used for proposed development and flood insurance purposes.
  • The Indiana Floodplain Information Portal (INFIP) displays the Best Available Floodplain mapping as well as the BFE.
  • The layers tab allows the user to view the effective layer.
  • A FARA can be generated by selecting “run” once a point is selected.
  • A BFE will be provided for the site, then the FARA should be downloaded and saved by the user for future reference.
  • There is the opportunity for users to submit a site for review if they wish to contest the FARA, if their site is near a stream without a mapped floodplain/floodway, or if their point is nearest to a stream with no floodplain and the tool took the BFE from a different stream.

First-time users of the site are encouraged to review the Indiana Floodplain Information Portal help document.
