Rockland must now wait for Maine Department of Transportation officials to determine what, if any, assistance the city will receive for repairing a massive sinkhole that developed late Monday afternoon.

A regional employee from the DOT met Tuesday morning with city officials to discuss how to repair the sinkhole next to the Rockland Golf Course parking lot on Old County Road.

City Manager Rosemary Kulow noted that Tuesday was a state government shutdown day and thus the DOT employee’s supervisors were not available. Photographs have been e-mailed to those officials and she said she hopes the city will receive some word on Wednesday, Feb. 17.

Plans for the repairs will need to be developed by an engineer, she said. She said she does not know if the state will provide the engineering or the city will have to contract for the work.

Kulow said Dragon Products in Thomaston has agreed to donate fill material for the hole that is estimated to be 25 to 30 feet wide and 50 feet deep.

The city manager said the date for when repairs will be made was to be determined after the meeting with the state transportation department. She said in her initial conversation with the state it seemed that the expense of repairs would have to be borne by the city.

There was no estimate on the cost of repairs.

Kulow said the road will be closed for at least a few days.

The sinkhole is located adjacent to a former limestone quarry.

David Hoch, who worked for the Rockport Lime Company for 30 years, said that while he is not as familiar with that quarry as he is with many others in the area, he believes the crews would sometimes dig into the side of the quarry and under existing roads.

The sinkhole does extend to the wall of the adjacent quarry. Hoch said he is not aware of any tunnels that led from that quarry to other nearby quarries.

He said that quarry had not operated in his 80 years of living in Rockland. He estimated the depth of that quarry at about 150 feet.

Harold Simmons, the president of the Rockland Historical Society, said the road, which was then the county road, was moved to allow for the quarry to expand.

Hoch said that, perhaps in the 1960s, there was an effort to fill that quarry but for some reason it was stopped.

The city of Rockland used the quarry for decades for disposal of demolition debris. That was stopped in the early 1980s at the insistence of the Maine Department of Environmental Protection.

The hole was detected late Monday afternoon. Concrete barriers were brought to the scene by the state transportation department, blocking vehicle access on both sides. Wooden barriers were erected at the intersection of Route 17 and Old County Road and a flashing sign was put up to warn motorists of the sinkhole.

The city had public works employees stationed at the scene to prevent youngsters from trying to play near the hole.

Aqua Maine Water Company was at the scene and the city manager said it installed shutoffs in the event that the sinkhole widens and threatens a water line.

The city police department received a call from a motorist at 4:51 p.m. saying there was a big pothole on Old County Road. After an officer arrived and saw what was occurring, the road was blocked on both sides of the hole.
