Skagit County, WA flood risk explained
Flood hazard in Skagit County sits at the 91.4th national percentile, well above the national norm for flood hazard; split between inland river flooding (about once every 3 years) and coastal storm surge (about 3.4 times a year). That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Skagit County
FEMA hasn't published a residential structure count for Skagit 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, 4.9% of all residential structures in Skagit County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
