Maui County, HI flood risk explained
Flood hazard in Maui County sits at the 93.7th national percentile, well above the national norm for flood hazard; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 4.3 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Maui County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Maui County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 4.8% of all residential structures in Maui County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Maui County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Maui County ranks 216 — 1 being the highest hazard nationally — and 430 by population among all 3144 counties covered here, where 1 is the largest. Maui County, Hawaii is home to about 163,688 people across 1,161.54 square miles of land.

Where Maui County's figures come from
Every figure on this page traces to a named FEMA dataset, documented in the methodology guide. Maui County's compliance figure is one of the ones affected by FEMA's incomplete denominator data — the data quality guide explains what that means and how many counties it touches.
