Sinkhole could threaten south Crestview homes

Sinkhole Antioch Estates

This sinkhole formed between two homes in southwest Crestview last week, caused by a leaking underground drain pipe that channels storm water runoff from the hill opposite the homes.

CRESTVIEW — The City Council has unanimously approved Public Works’ request to repair a leaking 18-inch storm-water runoff pipe that caused a sinkhole to form on Denise Drive.

Public Works Director Wayne Steele said a resident alerted him July 17 that the sinkhole had appeared between his house and a neighbor's home in the Antioch Estates subdivision.

An underground video inspection revealed three holes have appeared in the pipe, most likely aggravated by the excessive recent rainfall, Steele said.

The pipe — which runs from a drain on Denise Drive at the base of a hill opposite the homes — empties into a retention pond below a sharp slope behind the residences.

"The small sinkhole over the weekend turned into a large sinkhole," Steele said.

Because the pipe is buried 15 feet below the ground, it is impossible to dig it up for replacement, particularly given the close proximity of the two houses.

The solution, Steele said, is to install a Fiberglas liner the pipe’s length from the street to the retention pond.
