WHAT IS A FLOOD MAP?<\/span><\/strong><\/h2>\n

Flood maps are an important part of the National Flood Insurance Program (NFIP) as it show a community\u2019s risk of flooding.\u00a0 Specifically, flood maps show a community\u2019s flood zone, floodplain boundaries, and base flood elevation.\u00a0 These regulatory flood maps are called a Flood Insurance Rate Map.\u00a0 FEMA maintains and updates the flood hazard data through risk assessments, which are used to revise the Flood Insurance Studies (FIS) and Flood Insurance Rate Maps (FIRMs).<\/p>\n

Property owners, insurance agents, lenders, design professionals, and government officials are among the many NFIP stakeholders that utilize the FIS and FIRM maps:<\/p>\n

–\u00a0 as a basis of determining applicable floodplain management regulations for development within the floodplain;\u00a0<\/em><\/p>\n

–\u00a0 to determine flood insurance requirements and policy premiums; and<\/em><\/p>\n

–\u00a0 to help guide mitigation actions to reduce future exposure to flood risk .<\/em><\/p>\n

HOW TO VIEW AND OBTAIN THE FIRM MAPS<\/span><\/strong><\/h2>\n

The Department of Land and Natural Resources has developed and maintains the Hawaii Flood Hazard Assessment Tool (FHAT). The FHAT is an informational map viewer that displays FEMA’s Geographic Information Systems (GIS) version of the FIRM map.\u00a0 User can search by area of interest, address, TMK number, stream or watershed name, and by a specific Letter of Map Change (LOMC).<\/p>\n

PRELIMINARY FLOOD HAZARD DATA<\/a><\/span><\/p>\n

Preliminary flood hazard data provide the public an early look at their home or community\u2018s projected risk to flood hazards. Preliminary data may include: new or revised Flood Insurance Rate Maps (FIRM), Flood Insurance Study (FIS) reports, and FIRM Databases.<\/p>\n

NATIONAL FLOOD HAZARD LAYER<\/span><\/a><\/p>\n

National Flood Hazard Layer<\/a> is a geospatial database made from effective flood maps and Letters of Map Change (LOMC) delivered to communities.<\/p>\n
