I live on this street and about a year ago a Fulton County truck and crew came thru checking the problems with our street sinking. I spoke with one of the crew members and asked what they were looking for. He explained that there is a problem with the main sewer line under the street and it is causing these problems. This wasn't the first time a crew had been out to check the sewer line, so there must be a significant problem. About 4 years ago, we had an area in the street right in front of our home that was even worse than this current spot. It was repaired when the street was resurfaced, but the Fulton County employee confirmed there is still a problem with the sewer line under the street and he explained that it runs all the way down into the cul de sac at the bottom of the hill.
