Technical Mapping Advisory Council

The Technical Mapping Advisory Council (TMAC) is a federal advisory committee established to review and make recommendations to FEMA on matters related to the national flood mapping program authorized under the Biggert-Waters Flood Insurance Reform Act of 2012.

The national flood mapping program provides flood maps to inform communities about the local flood risk and help set minimum floodplain standards so communities may build safely and resiliently. The Flood Insurance Rate Maps (FIRMs) established under the program help determine the cost of National Flood Insurance Program flood insurance which helps property owners financially protect themselves against flooding.

The TMAC reviews the national flood mapping activities authorized under the law and prepares recommendations for the FEMA Administrator. The TMAC also produces an annual report on the impacts of climate sciences and future conditions and how they may be incorporated into the mapping program. The TMAC is comprised of representatives from federal, state, local and private sector organizations as mandated in the Biggert Waters Reform Act of 2012 and governed by the Federal Advisory Committee Act (FACA) requirements.

The TMAC holds public meetings throughout the year.  Public meeting notices and information are published in the Federal Register and can be searched with the keyword “TMAC.”
