Homeowner Near Deep Crack In North Versailles Questions Mine Maps

NORTH VERSAILLES (KDKA) -- Dave Milko says it began as a hole about the size of a basketball, but now that hole has expanded into a 25-foot deep crack that runs in the alley behind his home and several others in North Versailles.

"We're pretty close to this mess, and it's scary stuff," said Milko.

The cause of the crack is unclear, but some people suspect mine subsidence or water draining from an underground mine.

Milko bought mine subsidence insurance, but has a question for the Department of Environmental Protection.

The DEP's current map showing undermined areas depicts an old mine near Woodland Road, but not directly underneath.

However, Milko found a DEP map from 2003 which shows there is a mine directly underneath.

"So my question to the DEP would be what has changed?" said Milko.

Neighbors worry not only about their homes but also a sewer line they say runs under the crumbling alley.

The DEP is scheduled to inspect the crack on Tuesday.
