Your home, one of your greatest financial investments, is a place that shelters you, your family, and most of your possessions from the elements of nature. Yet natural hazards such as coastal storms, floods, high wind, and tornadoes can threaten the inhabitants and contents of your home. The 2013 FEMA Barnstable County Coastal Flood Risk report found Yarmouth has a total of 8.9 square miles of Special Flood Hazard Area (SFHA). The SFHAs are predicted to be flooded in a major flooding event. The Town also has 3.6 square miles of Coastal High Hazard Area (CHHA), the portion of the SFHA extending from offshore to the inland limit of a primary frontal dune along an open coast or any other area subject to high velocity wave action from storms. In 2014 the Town adopted new Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMS). The FIRM maps define the SFHAs in Yarmouth, areas where the National Flood Insurance Program's floodplain management regulations must be enforced. Property owners in these areas are mandated to purchase flood insurance if they have federally backed bank mortgages.
