Boulder is the number one flash flood risk community in Colorado
Holiday Closures
In observance of the Labor Day holiday, all administrative facilities and Age Well Centers will be closed on Monday, Sept. 1. Some facilities and services will be open.
Boulder has a high flash flood risk due to its location at the mouth of several canyons and the number of people who live, work and recreate in the floodplains. When floods occur, there may be mere minutes to react. The best defense is to understand the risks, be prepared and know how to respond.
When you hear the siren or an emergency warning, tune in to local news or visit boulderodm.gov.
These are great steps to help prepare for and react to a flood event, but there is always more to know.
