In Saint Paul, Minnesota property owners and developers must follow local floodplain development rules when building or altering land in regulated flood zones.

Overview

Floodplain permits cover new construction, substantial improvements, and certain land alterations in mapped flood hazard areas. Saint Paul enforces local provisions that implement the National Flood Insurance Program; additional state standards may apply. Before work begins you generally must submit a site plan, elevation information, and a mitigation plan describing measures to reduce flood risk.

Responsible office: City of Saint Paul Department of Safety and Inspections (DSI). For program details and local submission instructions, see the DSI floodplain guidance City of Saint Paul DSI[1]. For state-level technical standards and mapping, consult the Minnesota Department of Natural Resources floodplain pages Minnesota DNR Floodplain Management[2].
