How much flood risk does Rush County actually carry?
Rush County lands at the 6.3th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Rush County's flood-insurance compliance gap
Rush County is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Rush County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Where Rush County ranks
Rush County sits at rank 2957 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 2971 of 3144 by population (1 is biggest). Rush County, Kansas is home to about 2,810 people across 717.763 square miles of land.
