The Office of the Comptroller of the Currency (OCC), Board of Governors of the Federal Reserve System (Board), Federal Deposit Insurance Corporation (FDIC), the Farm Credit Administration (FCA), and the National Credit Union Administration (NCUA) (collectively, the Agencies) are amending their regulations regarding loans in areas having special flood hazards to implement certain provisions of the Homeowner Flood Insurance Affordability Act of 2014 (HFIAA), which amends some of the changes to the Flood Disaster Protection Act of 1973 mandated by the Biggert-Waters Flood Insurance Reform Act of 2012 (Biggert-Waters). Specifically, the final rule requires the escrow of flood insurance payments on residential improved real estate securing a loan, consistent with the changes set forth in HFIAA. The final rule also incorporates an exemption in HFIAA for certain detached structures from the mandatory flood insurance purchase requirement. Furthermore, the final rule implements the provisions of Biggert-Waters related to the force placement of flood insurance. Finally, the final rule integrates the OCC's flood insurance regulations for national banks and Federal savings associations. The Agencies plan to address the private flood insurance provisions in Biggert-Waters in a separate rulemaking.
