Missouri occupies the confluence of the Missouri and Mississippi rivers at St. Louis — two of the largest rivers in North America — creating a state with some of the most extensive mapped floodplains in the nation. The 1993 Great Flood of the Mississippi remains the largest and most economically damaging river flood in US history, inundating over 50,000 square miles and causing $15 billion in damage across Missouri and surrounding states. The 2019 Missouri River flood was historic in its own right, setting records at multiple gauge stations and breaching levees across western Missouri from Atchison to St. Charles. The Meramec River in the St. Louis metropolitan area creates a significant recurring flood hazard in suburban communities like Valley Park, Arnold, and Eureka. Missouri's bootheel region along the St. Francis River in the state's southeastern corner is a low-lying agricultural and residential area with chronic flood exposure.
Missouri has approximately 35,000 NFIP policies, concentrated in St. Louis metro-area counties along the Meramec and Missouri rivers, Buchanan County (St. Joseph), and the bootheel counties. Risk Rating 2.0 brought moderate changes to Missouri's policy base, with some high-value riverfront properties in the St. Louis metro seeing increases. The statewide average of approximately $640 per year is consistent with other Midwestern river states. Private flood insurance has essentially no commercial availability in Missouri outside the Kansas City and St. Louis metros.
Homeowners and renters policies categorically exclude flood damage. You must purchase a separate flood policy through the National Flood Insurance Program (NFIP) or a private flood insurer. Note: there's a standard 30-day waiting period from purchase to coverage, so don't wait until a storm is forecast.
NFIP residential policies cap building coverage at $250,000 and contents at $100,000. Homes worth more than these limits should consider 'excess flood' coverage through a private insurer or a fully-private flood policy with higher limits.
Major flood event affecting Missouri: 2024 Missouri River flooding; 2019 record Missouri River flooding. Repeated severe events tend to push up local NFIP premiums and shift more properties into mandatory-purchase Special Flood Hazard Areas.
💡 Missouri Pro Tip
Flood insurance is required for federally backed mortgage holders in Missouri SFHAs — which include extensive floodplain areas along the Missouri River from Kansas City to St. Louis, the Mississippi River border from Hannibal south to the bootheel, the Meramec River valley in the St. Louis metro, and the St. Francis River lowlands in the southeast. Missouri's floodplains are among the most extensively mapped in the US following the 1993 and 2019 flood events. St. Louis metro homeowners near any river or creek should seriously evaluate coverage given the region's repetitive flood history.
Missouri's average NFIP premium is approximately $640 per year. High-risk Missouri River floodplain properties in the Kansas City or St. Charles metro areas typically pay $700–$1,600. Meramec River floodplain properties in the St. Louis suburbs may pay $800–$1,800. Mississippi River border communities in Hannibal, Cape Girardeau, or the bootheel typically pay $700–$1,500. Zone X properties in lower-risk areas can access Preferred Risk Policies at $350–$550.
NFIP flood insurance in Missouri covers riverine flooding from the Missouri, Mississippi, Meramec, Osage, Gasconade, and other rivers (the dominant peril), surface water flooding from intense rainfall, levee overtopping and failure resulting in general surface inundation, backwater flooding in low areas where drainage is blocked by high main stem river levels, and mudflow caused by flooding. It does not cover basement seepage from saturated soils during prolonged flood events, sump pump failures, or sewer backup unless directly from external surface flooding. Missouri homeowners in the St. Louis metro should review their sewer backup coverage separately.
