Four businesses house in a small retail complex on Jeffco Boulevard in Arnold had to close after part of a retaining wall collapsed this morning (July 29), the Rock Community Fire Protection District reported.
Two homes in the 1200 block on Windcrest Circle – a neighborhood below where the wall collapsed – also were evacuated, the Rock Community Fire Protection District reported.
No one was injured in the collapse, which the Arnold Police Department reported to the fire district at about 9:15 a.m. today, Rock Fire spokesman Ron Harder said.
The portion of the wall that came down is behind the Jimmy John’s sandwich shop, 1266 Jeffco Blvd.; Cold Stone Creamery, 1270 Jeffco Blvd.; Smoothie King, 1272 Jeffco Blvd.; and a Verizon retail store, 1276, Jeffco Blvd. The complex is between McClain Drive and Ridgecrest Drive, which is near the Arnold Post Office and across the street from the Arnold Walmart Supercenter.
Arnold Community Development Director David Bookless said the city’s building commissioner has directed the property owner to have a certified structural engineer assess the situation and propose remedies. Officials from Spire and Public Water Supply District No. 1 also inspected the area, Rock Fire reported.
“It could take a couple of days. It might take a few weeks,” Bookless said about getting an engineer to investigate the situation. “Once the engineer provides something to the building commissioner that he finds satisfactory, people can move back into (the businesses) and repairs can be made.”
Bookless said this afternoon he did not know what caused the collapse.
He also said the homeowners could return to their houses at their own risk.
The concrete from the wall fell behind the homes and did not appear to go into the homes’ yards since some concrete pieces were stopped by a fence.
