Property owners investigating cause of Dillon rock slide

Special to the Daily/Lake Dillon Fire-Rescue

DILLON – Officials are still investigating the cause of a rock slide behind Dillon’s Walgreens earlier this week. A water main break closed Dillon Valley’s Little Beaver Trail until further notice, but testing is being done to determine why the retaining wall failed.

According to reports from Lake Dillon Fire-Rescue. the water main break sent water down the 60-foot retaining wall, causing some of it to slump. Two homes located below the slump were evacuated and Little Beaver Trail was closed near 1st Bank. There were no injuries or accidents resulting from the break.

“It’s not probably dangerous for property owners and businesses,” Dillon’s public works director Eric Holgerson said. “There’s still a little bit of movement. One house is directly underneath it, but it’s not in imminent danger.”

Evergreen Road is being used to access Dillon Valley until further notice. Local traffic can access the Dillon and Silverthorne sections of Little Beaver Trail, however.

Holgerson said the owner, Pace Properties, is conducting testing to determine the stability of the slope.

“They’re investigating the cause of the failure, and if it had to do with the retaining wall,” he said. “We had a meeting with the property owners yesterday, and they informed the town of testing and failure investigations.”

Another meeting with Pace Properties and the Town of Dillon will possibly be set for Friday.

“The hope is that we’ll have preliminary findings on Friday to figure out how to move forward,” said town manager Devin Granbery. “They’re trying to figure out what exactly happened. At this time we just don’t know. We need the experts to come in to give us an idea of what happened.”
