How much flood risk does Colonial Heights city actually carry?
Colonial Heights city lands at the 43th 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 coastal storm surge rather than inland rivers — FEMA's model puts a surge event here at about 3.7 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires

Across all residential structures in Colonial Heights city, not just the ones FEMA mandates, 0.7% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
