Your specific zone determines insurance cost, build elevation, and permit requirements in Bloomington, IN.

Full Breakdown

040 of the Unified Development Ordinance applies to every area of special flood hazard (SFHA) within Bloomington's jurisdiction, including any annexed later. The rule is blunt: no structure may be located, extended, converted or structurally altered within an SFHA, and no land or stream within an SFHA may be altered, without full compliance with the UDO. 050(d). The Common Council appointed the City's Planning Director, or their designee, to administer the program as the Floodplain Administrator, who reviews applications, interprets floodplain boundaries, issues or denies permits, conducts substantial-damage determinations, and can issue stop-work orders or revoke a permit obtained through a false statement.

Bloomington's SFHA boundaries come from the Flood Insurance Study and Flood Insurance Rate Map dated December 17, 2010, plus later FEMA updates and, where floodway limits are not mapped, the best available flood layer from the Indiana Department of Natural Resources. Construction within a mapped floodway also requires a separate state permit under the Flood Control Act (Indiana Code 14-28-1) before the City will issue its own permit. Owners should expect the floodplain permit process to run in parallel with, not instead of, any Indiana DNR floodway authorization.

Violations & Fines

Failing to obtain a Floodplain Development Permit in the SFHA, or failing to comply with a permit's requirements or a variance's conditions, is a violation of the ordinance. The code directs that all such violations be treated as a common nuisance under the City's Zoning Code, and the Floodplain Administrator must also warn the owner that a willful violation can cause a Standard Flood Insurance Policy to be suspended.
