News & Announcements



January 27, 2016 - The U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA) has initiated the process which allows the public to officially comment on the Preliminary Digital Flood Insurance Rate Maps (DFIRMs) that were issued August 14, 2015.  Comments must be in writing and should be submitted to the County by April 26, 2016 to be included in the County’s appeal to FEMA. 

The U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA) is nearing the end of a multi-year effort to update and modernize the Flood Insurance Rate Maps (FIRM) for Hawai‘i County. The updated maps will help community officials and local residents better identify known flood risks and when finalized, will be used for flood insurance, land use and development decisions. 

Flooding is one of the major natural disasters in the United States. These maps can help residents make informed decisions about flood insurance options and flood protection measures.

The preliminary FIRM maps serve to revise and update information on the existence and severity of flood hazards in Hawaii County. The revised maps reflect the combined efforts of FEMA and Hawai‘i County.  The maps are available for viewing at the Hawai‘i County Department of Public Works Engineering offices at either 101 Pauahi St., Suite 7 in Hilo (808 961-8327) or 74-5044 Ane Keohokalole Hwy, Building D, 1st floor of the West Hawaii Civic Center in Kona (808 323-4850). They will also be available for online viewing on the State of Hawai‘i’s Flood Hazard Assessment Tool (FHAT) at
