About Flood Map Service Center
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 MSC 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 Effective information that you download or print from this site may change or become superseded by new maps over time.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
As of August 18, 2017, the FEMA Map Service Center (MSC) transitioned from Hypertext Transfer Protocol (HTTP) to Hypertext Transfer Protocol Secure (HTTPS), which secures data entered by users. Users should update all bookmarks, including any systems or processes that access MSC data or data services directly via URL.
As of August 1, 2017, the FEMA National Flood Hazard Layer (NFHL) transitioned from Hypertext Transfer Protocol (HTTP) to Hypertext Transfer Protocol Secure (HTTPS). This may impact NFHL web services. For more information on how NFHL GIS services will be impacted, please visit the NFHL GIS Services page at https://hazards.fema.gov/femaportal/wps/portal/NFHLWMS.
As part of this security protocol change, users that access the NFHL through Google Earth must install the Google Earth Version 7.3 or higher and download the new .kmz files which can be found on the Using the National Flood Hazard Layer Web Map Service (WMS) in Google Earth web page.
A patch is now available for the Hazus 4.0 Hurricane Wind model, fixing two defects: underestimation of losses for manufactured housing, and overestimation of losses for large and medium hospital facilities. Click HERE to download the patch. To install the patch, follow these steps:
- Download the patch and unzip to your local machine in the C:\ProgramFiles(x86)\Hazus-MH folder
- Navigate to the folder where the patch was unzipped. The extracted files will be in a folder called "HuPatch_v2." Please note, some extractors will create a second subfolder with the same name, and the patch files will be located there.
- Open the folder HuPatch_v2 which contains the patch files.
- Double-click on the executable file called HuPatch40SP1 to launch the patch. A message will display when the patch installation has successfully completed.
Please note: If Hazus is not installed in C:\ProgramFiles(x86)\Hazus-MH, or is only a partial install, a message will display that Hazus cannot be found on the machine. If this occurs, please contact the Hazus Help Desk for assistance in deploying the patch.
