Mapping Palai-Waiakea Stream

Owners of property along the Palai Stream in South Hilo are receiving letters from the County of Hawai‘i, Department of Public Works this week.  The letter informs them of proposed floodplain changes to the “Flood Insurance Rate Maps” or FIRMs covering their property, the processes before FIRMs are effective, and the course of action if a property is mapped incorrectly.

In April 2014, the Department of Public Works submitted a Letter of Map Revision (LOMR) to the Federal Management Agency (FEMA) proposing changes to the existing 1988 FIRMs for Palai Stream in South Hilo. 

These proposed changes submitted to FEMA are based on better topographic data and an improved modeling technique to determine the flood risks, and flood insurance rates that help Hawai‘i County with floodplain management.

The benefits of updated Palai Stream Flood Study Flood Insurance Rate Map will provide:

  • a better understanding of flood hazards for planners; and
  • detailed information where to build, and to make financial decisions about protecting a home or business property.

The County of Hawai‘i and the U.S. Army Corps of Engineers (USACE), continue to work on solutions to mitigate damage during flood conditions.

Your flood risk is indicated by three colors: Grey is the current flood risk.  The proposed changes are in blue and red.  The green lines are engineer marks, as are the cross section in black. These are large files and will take a second to download.
