VIEW MAPS & PROVIDE FEEDBACK
The interactive web map (use the button above) shows detailed flood risk zones and related FEMA map amendments that are currently regulated throughout unincorporated Boulder County as Floodplain Overlay Zoning District. This map will update as new FEMA maps become effective throughout Boulder County and as the Boulder County Board of County Commissioners (BOCC) adopts best available information.
The Boulder County Regulatory Flood Risk Zones were updated on Jan. 10, 2020 to reflect changes to the Floodplain Overlay District based on FEMA’s Preliminary Flood Insurance Rate Maps (FIRMs) for stream reaches studied by the Colorado Hazard Mapping Program (CHAMP). The Preliminary FIRMs were adopted by the BOCC via Docket Z-19-0001.
Visit the interactive web map (use button above) to view FEMA’s Preliminary Flood Insurance Rate Maps (FIRMs) for stream reaches studied by CHAMP. We expect the CHAMP Preliminary FIRMs will become effective FIRMs in 2021, pending any appeals received by FEMA. At that time, the updated CHAMP mapping will be used for flood insurance rating.
