The scope of the Hawaii County Countywide Revision effort includes processing the NRCS 2010 imagery dataset to be used as the base layer on revised preliminary maps, performing a quality review of the County’s georectified FIRM panels, digitization of riverine boundaries to the georectifeid FIRM panels, redelineation of riverine and coastal boundaries within the USACE LiDAR footprint of Hilo, incorporation of the County’s funded North Kona, Puna and Palai Stream Studies and a three-part training series on coastal analysis and mapping methodologies. This resultant effort will produce revised preliminary maps for the 114 printed panels.
Preliminary FIRM panels were released on August 14, 2015. The maps are available for viewing on FEMA's preliminary website located here
, or on the State of Hawaii's Flood Hazard Assessment Tool (FHAT) located here
The preliminary meeting was held in Hilo on August 17th and the first open house meeting was held directly afterwards. Residents and property owners were encouraged to attend one of two Informational Public Meetings on August 17th and 18th. Personnel from the FEMA, the State of Hawaii’s Department of Land and Natural Resources, and Hawaii County were available to answer questions, concerns, and provide information on the mapping timeline and appeals process.
