Not only is flooding one of the most common and costly disasters, flood risk can also change over time because of new building and development, weather patterns and other factors. Although the frequency or severity of impacts cannot be changed, FEMA is working with federal, state, tribal and local partners across the nation to identify flood risk and promote informed planning and development practices to help reduce that risk through the Risk Mapping, Assessment and Planning (Risk MAP) program.

    Risk MAP supports community resilience by providing data, building partnerships, and supporting long-term hazard mitigation planning. In particular, Risk MAP’s Flood Risk Products work alongside regulatory products to provide flood risk information and support your community’s overall floodplain management and hazard mitigation strategies.

    The Flood Risk Products and datasets present information that can enhance hazard mitigation planning activities, especially the risk and vulnerability assessment portion of a hazard mitigation plan, and the development of risk-based mitigation strategies. Flood Risk Products can also help guide land use and development decisions and help you take mitigation action by highlighting areas of highest risk, areas in need of mitigation, and areas of floodplain change.

    The Risk MAP program promotes planning and development practices to help reduce that risk.

    Whether you are an engineer performing a flood risk analysis, a state planner designing and implementing a hazard mitigation plan, or a well-informed homeowner who has purchased flood insurance, empowering individuals, organizations and communities to take proactive steps to reducing flood risk is an essential piece of Risk MAP.

    Managing Organizations

    FEMA’s mission is to help people before, during and after disasters. The challenges posed by more intense storms, frequent heavy rain, heat waves, drought, extreme flooding, and higher sea levels could lead to increased risks from disasters faced by communities and the emergency management professionals serving them.
