Flood Facts

Floods are the most common and widespread of all natural hazards. Some floods develop slowly, but flash floods can happen in just minutes.

Flood prone areas have been identified in 267 cities and towns and in all of the 64 counties in Colorado. Over 250,000 people are living in Colorado's floodplains. There are estimated to be 65,000 homes and 15,000 commercial, industrial, and business structures in identified floodplains. There are likely many more structures located within unmapped flood hazard areas. The value of the property, structures, and contents located in the identified floodplains is estimated to be over 11 billion dollars (1996).

Average annual flood losses in Colorado are estimated to be $17,600,000 in property damage based on data from 1896 to 1984.

Cumulative flood losses for the most damaging floods in Colorado between the turn of the century and 1993 include 331 people killed and $3.3 billion (1995 dollars) worth of property damage.
