The U.S. Department of Transportation has awarded Colorado $22.79 million for disaster recovery related to 2013 flooding and a rockfall in the San Juan Mountains last summer, U.S. Sen. Cory Gardner announced.

The events “caused significant damage to our infrastructure that we are still dealing with today,” Gardner said. “I’m pleased this much-needed funding has been made available to help our communities recover.”

These funds are in addition to the nearly $125 million awarded to Colorado by the Federal Highway Administration in 2017 for recovery from 2013 and 2015 floods, as well as a 2016 rockslide on Interstate 70 through Glenwood Canyon, Gardner’s staff said.

Flooding along a 150-mile stretch of the Front Range from Fort Collins southward to Colorado Springs began Sept. 12, 2013. Just four days later, six people were confirmed dead and 1,000 remained missing, according to climate.gov.

Flooding was so severe that it qualified as a 1,000-year event, “meaning that any one year has just a 1-in-1,000 chance of experiencing such heavy precipitation,” according to the website.

A July 8 rockfall resulting from heavy rain covered U.S. Highway 550 at Red Mountain Pass in 4 to 10 feet of rock and mud, the Durango Herald reported last summer.
