Sinkhole on Eldorado Drive repaired
Problem was caused by damage to storm pipe

Repair work on the sinkhole that appeared on Eldorado Drive Friday was almost complete on Monday.
“The sinkhole is repaired and the crews are doing some road restoration work right now,” said Greg Grueber, utilities manager for the city. “We’re going to be preparing it for its finished asphalt.”
Grueber expected by Tuesday afternoon the road would be completely open. As of Monday afternoon there was one lane open and motorists were being asked to yield to oncoming traffic.
While it sounds dramatic, the sinkhole itself wasn’t very large. Public works expanded it to about 18 inches while poking at the asphalt to see what the problem was, and dug down around 5.5 or six feet.
Grueber said the cause was “a utility conflict. There was some damage to storm water infrastructure in the area caused by, it looked like, some construction activity that occurred there in the past.”
It appears logical a directional drilling company that worked in the area punctured one of the storm pipes, he said.
“We didn’t know of it until the road started to form a sinkhole,” Grueber said.
The issue was spotted by a public works employee who reported it to the office.
“Our inspections found the root cause and we actioned the repair immediately,” he said.
Grueber offered kudos to the nearby residents who were cooperative with the inconvenience of construction and the road closure that occurred along Eldorado between Erin Ridge Drive and Essex Close.
The appearance of a sinkhole is not too common in St. Albert, Grueber said, noting there’s maybe one every couple of years or so.
If residents do spot a sinkhole, however, they should contact public works immediately.
