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 (NFIP), including your community’s flood map, called a Flood Insurance Rate Map (FIRM).
Effective FIRMs and any amendments or revisions that apply to them may be accessed through the site’s Address Search, in addition to the full range of products accessible through the Search All Products function. All MSC products and services are available at no cost.
Your local Community Map Repository, usually located in the planning and zoning office, also has copies of flood maps. Please contact a FEMA Map Information eXchange Map Specialist to determine the location of your Community Map Repository.
