FEMA Flood Map of the City of Boulder

The above noted maps were prepared for the Urban Drainage and Flooding District (UDFD) and are meant to be for general informational purposes only. Floodplain maps are often under revision and the official FEMA Flood Insurance Maps are what are used to determine what properties are contained in floodplains and who must have appropriate insurance. For the most updated maps in your area, contact FEMA's Flood Hazard Mapping site or, in the city of Boulder, the office of Floodplain and Wetlands Management (303) 441-3240
