Floodplain management is the operation of a community program of preventive and corrective measures to reduce the risk of current and future flooding, resulting in a more resilient community. These measures take a variety of forms, are carried out by multiple stakeholders with a vested interest in responsible floodplain management and generally include requirements for zoning, subdivision or building, building codes and special-purpose floodplain ordinances. While FEMA has minimum floodplain management standards for communities participating in the National Flood Insurance Program (NFIP), best practices demonstrate the adoption of higher standards which will lead to safer, stronger, more resilient communities.
FEMA’s Floodplain Management provides tools and resources to help communities navigate NFIP requirements and implement higher standards of floodplain management. State and federal agencies, tribal governments, local communities and property owners have a role in reducing flood risk and helping communities become more resilient. From states providing strong model ordinances, to communities adopting and enforcing higher-standard building practices, to property owners elevating their homes, everyone can play a part in making communities safer and more resistant to flood disasters.

Flood Map Service Center : Determine Floodplain Status
The FEMA Flood Map Service Center (MSC) is the official public source for flood hazard information produced in support of the National Flood Insurance Program (NFIP). Use the Map Service Center to find your official flood map, access a range of other flood hazard products, and take advantage of tools for better understanding flood risk.
FEMA flood maps are continually updated through a variety of processes. Effective information that you download or print from this site may change or become superseded by new maps over time. For additional information, please see the Flood Hazard Mapping Updates Overview Fact Sheet
These documents have recently been added to the FEMA Library:
- Critical Facilities - for local community officials and emergency managers to learn the basic requirements of critical facilities when they are located in or near a high flood hazard area. It discusses mitigation options and design guidance information to providing enhanced protection to critical facilities.
- Higher Standards - for local community officials and gives an introduction of what it means to go above and the beyond the minimum required standards to participate in the National Flood Insurance Program (NFIP). It also explains why it is beneficial to utilize higher standards in their community, and how they can save their citizens money by reducing their flood insurance premiums if they adopt higher standards and join the Community Rating System (CRS).
- Limit of Moderate Wave Action (LiMWA) - for local officials and coastal property owners to explain wave effects, the limit of moderate was action zone, and why it is important to design structures to a coastal standard in those areas. It provides LiMWA Quick Facts to illustrate basic concepts of the LiMWA and provides helpful links to learn more.
