Dubuque officials to start process of sealing sinkhole after 3 years

DUBUQUE, Iowa (KWWL) -- After three years a sinkhole in Dubuque is finally on the path to being filled. Through a partnership between Dubuque and Iowa’s Department of Agriculture and Land Stewardship the city has hired S&S Construction of Dubuque to seal the hole. 

The sinkhole first emerged in September of 2018 in Barbara and Robert Friedman’s side yard. It has since grown to butt against their garage, causing damage and safety concerns for neighbors. Multiple attempts were made by the Friedman's to fill the hole over the years but the sinkhole swallowed them all. 

In December the Friedman’s sent a letter to Governor Reynolds asking for assistance. She authorized the IDALS to fund the sealing of the hole. 

S&S Construction plans to dig down to what they hope is solid rock and then seal the origin of the sinkhole with a cement cap.

Bob Schiesel, Dubuque’s assistant city engineer, hopes the initial dig will reveal more details about the sinkhole.

“We won’t know until we get the whole thing opened up and we can actually see what's down there,” he said. “But we’re hoping that we’re able to see a crevice or something.”

Utilities in the area have to move service before digging can begin. Because of this the earliest excavation will be started is mid next week.
