Full Breakdown

Any development activity within an area of special flood hazard (SFHA) in the City of Evansville, Indiana, construction, fill, excavation, utility installation, or placing a manufactured home or recreational vehicle, needs a floodplain development permit first. SFHAs are the Zone A/AE areas delineated on the FEMA flood insurance rate map for Vanderburgh County, Indiana and incorporated areas, dated January 29, 2021. The Floodplain Administrator, an Evansville-Vanderburgh Building Commission employee, reviews and issues the permits; this is the City's own Title 16 ordinance, distinct from Vanderburgh County's separate floodplain rules for unincorporated areas.

Building without a floodplain development permit, or violating permit conditions, is a common nuisance under EMC 15.05.520; each day of continued violation is a separate offense, and the Building Commission may warn the owner that a willful violation can suspend NFIP flood insurance coverage.
