Flood Risk Map Viewer
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. FEMA is working with federal, state, tribal and local partners across the nation to identify flood risk and help reduce that risk through the Risk Mapping, Assessment and Planning (Risk MAP) program.
Preliminary data is presented as the best information available at this time and include new or revised Flood Insurance Rate Maps (FIRMs), Flood Insurance Study (FIS) reports and FIRM Databases.
• A FIRM (also referred to as a flood map) is the official map that shows Special Flood Hazard Areas (SFHA) and the risk premium zones applicable to a community. Risk zones indicated on a FIRM providea a basis for establishing flood insurance coverage premium rates offered through the National Flood Insurance Program (NFIP).
• FIS reports provide background information on the analysis performed and more precise data on the flood elevations in a community
• A FIRM Database is a collection of the digital data that are used in Geographic Information Systems (GIS) applications for creating new FIRMs. These datasets cover a county or a community
What are the Benefits of Preliminary Data?
The release of preliminary data is an important step in a community’s flood mapping lifecycle. There are several benefits for the public and professionals in viewing their community’s preliminary data before it becomes an effective FIRM:
- Allows the public to voice their opinions or concerns regarding how the data may affect them or to question data accuracy
- Insurance agents can compare existing FIRMs with preliminary FIRMs to see how their clients may be affected. However, policies cannot be written using preliminary data
- Loan and mortgage brokers can use preliminary data as a guide to determine whether a property may be mapped into a high-risk area, allowing the borrower to be informed of any changes or requirements before finalizing the loan
- Real estate agents and brokers can determine what changes are likely to occur and how it might affect any properties for sale
- Engineers, developers and builders can plan for safer construction
What is the Difference Between Preliminary and Effective Data?
Preliminary data are for review and guidance purposes only. By viewing preliminary data, the user acknowledges that the information provided is preliminary and subject to change. Preliminary data, including new or revised FIRMs, FIS reports and FIRM Databases, are not final and are presented on the FEMA Flood Map Service Center (MSC) as the best information available at this time. Additionally, preliminary data cannot be used to rate flood insurance policies or enforce the federal mandatory purchase requirement. Preliminary data will be removed and replaced once effective data are available.
Unlike preliminary data, effective data and maps are official and should be used for National Flood Insurance Program (NFIP) purposes and viewing risk premium zones applicable to a community. If you don’t want to view preliminary data, go to your community’s effective FIRM or effective FIS Report available on the FEMA Flood Map Service Center (MSC).
