Description

more
Following the 2013 flood, the Colorado Water Conservation Board (CWCB) initiated a program to re-map the predicted 1% chance regulatory floodplain (100-year flood zone) of the most affected waterways. The program was named the "Colorado Hazard Mapping Program" or "CHAMP." This has been adopted by the Boulder County Commissioners, and will be used for regulatory decisions by the county. Not necessarily used for determining flood insurance.
