Flood Risk FAQs

  • FEMA’s Standard Flood Insurance Policy (SFIP) defines a flood as:

    • Two or more acres of normally dry land or two or more properties that are partially or completely submerged by water from any of these events:
      • Overflowing inland or tidal waters
      • Unusual, quick surface water runoff
      • Mudflows (rivers of liquid, flowing mud) caused by flooding
      • Collapse or sinking of land along a lake or other body of water caused by heavy waves or currents

  • High-risk flood areas begin with the letters A or V on FEMA flood maps.

    They are also known as special flood hazard areas (SFHAs).

    If you own a property in a high-risk zone and have a federally backed mortgage, you must purchase flood insurance.

    Over a 30-year mortgage, homes in these areas have a 1 in 4 chance of flooding at least once.

    Moderate- to lower-risk flood areas are designated with the letters B, C and X on FEMA flood maps.

    There is still a risk of flooding in areas with low or moderate flood risk. About 40% of NFIP claims come from outside high-risk flood areas. Although some lenders may not require flood insurance, FEMA recommends flood insurance to protect property owners from financial losses. It’s important to note that most homeowners and renters insurance don’t cover flood damage.

  • The NFIP uses many factors to evaluate a property’s flood risk:

    Your Property’s Location

    • Frequency of flooding in the area
    • Distance to multiple types of flooding sources, including the coast, oceans, rivers, and lakes
    • The ground elevation where the building is located relative to the elevation of the surrounding area and nearby flooding sources

    The Building’s Characteristics

    • Risk is greater for foundations underground or at ground level than those elevated above ground
    • Flood risk is lower for buildings with first floors that are higher off the ground
    • Buildings with more floors spread flood risk over a larger area
    • Individual units on a building’s higher floors have a lower risk of flooding than units on lower floors
    • Masonry walls perform better in flooding events than wood frame walls
    • A building with flood openings can have lower flood risk by allowing floodwaters to flow through the structure’s enclosure or crawlspace
    • Where the building’s heating/air conditioning, electrical panels, hot water heater and other equipment are located affect risk
      • Locating equipment above the first floor (or above floor level) lowers the risk of flood damage

  • Mitigating (reducing) flood risk protects your property against flood damage. Mitigation can also help to lower insurance costs.

    Common flood mitigation options include:

    • Moving or raising heating and cooling systems, water heaters, electrical panels and other utilities to reduce risk of damage. Consider using an attic, extra closet, or raised platform to elevate them
    • Filling in your basement. A basement is any area of a building with its floor lower than the ground. Crawlspaces that are below ground on all sides are considered basements
    • Elevating your property above the ground
    • Relocating your structure to an area with lower flood risk

    You can find more in the Homeowner's Guide to Retrofitting.

    If a flood is about to occur, you can take flood avoidance measures.

    Under current rules, the NFIP covers certain flood avoidance measures, including:

    • Up to $1,000 to protect insured property and
    • Up to $1,000 to move insured property away from a flood or imminent danger of flooding)

    Eligible expenses include:

    • Sandbags (including sand to fill them)
    • Fill (such as sand or gravel) to create temporary levees
    • Water pumps
    • Plastic sheeting and lumber
    • Labor of the property owner or a family member, covered at the federal minimum hourly wage ($7.25 in 2024)
