It's right next to an area that had been cordoned off a few weeks back, and the sinkhole was likely caused by drainage issues with all the heavy rain.
The sinkhole is fairly deep. WBTV's Steve Ohnesorge observed what appears to be a culvert box at the head of the sinkhole. The box was made with red brick, signifying how long it's been there.
Emergency officials have not released any other information about the sinkhole.

It's an eyeopener to see the changes happening so close to home. Amazing times we live in.
