A massive sinkhole in Philadelphia’s Mayfair neighborhood is raising safety concerns among residents who say the hole has grown significantly over the past six months. Neighbors said the sinkhole started as a much smaller hole in March but has since grown, leaving a massive pile of dirt at the site. The area is surrounded by cones and barricades, but neighbors told NBC10 they have seen teenagers climbing on top of the dirt pile — something they say is extremely dangerous. Residents are worried about the safety of children and drivers, the loss of parking and the stability of the street itself. The Philadelphia Water Department told NBC10 the hole is connected to a problem with a private sewer line. A contractor working through the city’s Homeowner Emergency Loan Program discovered Friday that conditions were getting worse and stopped work, according to the Water Department. The area has since been barricaded. The Water Department said plumbing work is expected to continue into next week. This story was originally reported for broadcast by NBC Philadelphia.
