Flood Maps: Floods are unpredictable. Because flood risk is always changing, communities use tools to understand their risk and take actions to protect their families, homes and businesses. ... Flood maps are one tool that communities use to know which areas have the highest risk of flooding. FEMA maintains and updates data through flood maps and risk assessments. Flood maps show how likely it is for an area to flood. Any place with a 1% chance or higher chance of experiencing a flood each year is considered to have a high risk. Those areas have at least a one-in-four chance of flooding during a 30-year mortgage. Floods don't follow city limits or property lines. Using a flood map, you can see the relationship between your property and the areas with the highest risk of flooding. There is no such thing as a "no-risk zone," but some areas have a lower or moderate risk. How to View and Obtain Flood Maps: The FEMA Flood Map Service Center (MSC) is the official online location to find all flood hazard mapping products created under the National Flood Insurance Program, including your community's flood map. ... Updates to flood maps are a collaboration between your community and FEMA. Every community that participates in the National Flood Insurance Program has a floodplain administrator who works with FEMA during the mapping process.
