The city of Boulder rests at the base of the Foothills of the Rocky Mountains and is home to Boulder Creek, its 14 tributaries and Boulder Slough (diverted water from Boulder Creek to fulfill irrigation company water rights). Due to our geographical location, the city of Boulder has the highest risk of flash flooding in the state of Colorado. Many neighborhoods throughout the city experience flooding during storm events, and some are at a higher risk to more extreme flooding due to their proximity to a major drainageway.
The city encourages all residents to be aware of their flood risk and take necessary precautions to help protect life and property.
