Reflects policies with an effective date in the trailing 13 months (July 1, 2025 through August 16, 2026) - a 12-month policy term plus a 1-month buffer for OpenFEMA's own reporting lag - as an approximation of currently active policies, not a certified point-in-time count. Policies renewed early in this window may be counted twice, so actual totals may be somewhat lower than shown. See national policies data.

What Your Flood Zone Means in Kahului

Kahului faces a combination of coastal and inland flood risks. Storm surge from hurricanes and tropical storms pushes seawater inland, while heavy rainfall simultaneously overwhelms rivers, bayous, and drainage infrastructure. This dual threat means flooding can come from multiple directions at once. The most common FEMA flood zone designations in Kahului are Zone AE, Zone VE, Zone X. FEMA's National Risk Index estimates the county's annual expected loss from inland flooding at over $59.4M. Properties in Kahului's VE zones face additional wave action risk beyond still-water flooding, which typically results in higher insurance premiums and stricter building requirements.

Combined coastal and inland flood exposure in Kahului means properties may face higher premiums than areas with only one flood source. FEMA's Risk Rating 2.0 accounts for multiple flood sources, including coastal surge distance, river proximity, and rainfall-driven flooding. If your property is in a Special Flood Hazard Area (SFHA) and you have a federally regulated or government-backed mortgage, federal law generally requires your lender to ensure you carry flood insurance.

Flood maps in areas with combined coastal and inland risk are among the most complex in the FEMA system. Major storms often trigger FEMA restudies that can significantly shift zone boundaries. Letters of Map Revision (LOMR) after hurricanes may expand SFHA coverage as new storm data is incorporated. Use our free lookup tool to check the current flood zone for any Kahului address.

How many Kahului properties have flooded repeatedly?

Maui County has 57 properties with multiple flood losses on record, including 9 severe repetitive loss properties. These are properties that have experienced four or more NFIP claims of $5,000+ or two claims exceeding the building value.

Can my Kahului property be removed from a high-risk flood zone?

Yes, if your property's natural ground elevation is above the Base Flood Elevation and FEMA inadvertently mapped it in a high-risk zone, you can apply for a Letter of Map Amendment (LOMA). A successful LOMA removes the property from the Special Flood Hazard Area, generally eliminating the federal mandatory flood insurance requirement. You will need an elevation certificate from a licensed surveyor. If a property was raised above the BFE with fill material, the process is a LOMR-F rather than a LOMA.

What is Base Flood Elevation in Kahului?

Base Flood Elevation (BFE) is the predicted height of floodwaters during a 1% annual chance (100-year) flood, shown on FEMA maps as an elevation number in feet above sea level. In Kahului's Zone AE and Zone VE areas, BFE lines appear on the FIRM as wavy contours labeled with elevation values. Properties with a lowest floor at or above the BFE typically qualify for significantly lower NFIP flood insurance premiums.
