The Board of County Commissioners (BOCC) will hold a hybrid Public Hearing on Docket Z-23-0001: Zoning Map Amendments to the Floodplain Overlay District on Tuesday, March 26 starting at 1 p.m.

The Colorado Hazard Mapping Program (CHAMP) has produced new regulatory floodplain maps for the waterways in unincorporated Boulder County most affected by the 2013 Flood. The county's Floodplain Overlay District is comprised of both the FEMA Flood Insurance Rate Map (FIRM) and the Boulder County Floodplain and Floodway. In 2017, 2018, and 2020, the county incorporated draft and preliminary CHAMP data into the Boulder County Floodplain and Floodway. Now, the CHAMP study will be incorporated into the FEMA FIRM as of autumn 2024.
