These unique valleys were created by rivers and streams that support wildlife habitat, agricultural operations, recreational opportunities and more. Our local waterways are a beautiful amenity - that can also be a powerfully dangerous force during flooding. What are floodplains and how are they managed? A floodplain is any land area susceptible to being inundated by floodwaters from any source. Floodplain management is the operation of a community program that reduces the risk of current and future flooding and helps create a more resilient community. Floodplain management includes a variety of preventative and corrective measures that are implemented by different stakeholders - all with a vested interest in responsible floodplain management. Measures generally include requirements for zoning, subdivision or building, building codes, and special purpose floodplain ordinances. The City of Missoula administers floodplain hazard management through the National Flood Insurance Program which includes floodplain permitting, regulations, and mapping within the city limits. Through management, the City works to reduce future flood losses and to promote health and safety through wise use and development within floodplains. For questions and information outside the City limits, please contact the Missoula County Floodplain Administrator.
