East Arlington sinkhole questions answered

JACKSONVILLE, Fla. -- In the Sterling Ridge subdivision residents are concerned about holes, several holes. 

"You don't know how deep some of them do," said David Norris. 

Several are near Norris backyard. The city Municipal Code  Enforcement recently cordoned off the area and condemned it, citing the holes are related to a failed septic tank system. Norris said that can't be.

"There is no septic system here," said Norris, "these homes were built in 1999."

The city has since back pedal on the condemnation sign saying there is a need for more investigation. So what's causing the holes?

The On Your Side asked a team from Foundation Professionals and Cal Tech testing to investigate the area; to give residents peace of mind

"We see a lot of this in Jacksonville," said David Brown of Foundation Professionals.

The soil experts made digs in various areas, they were testing resistance and discovered in some areas the soil is very soft.

They also examined the soil for content-organic and moisture.

Gary McCollum of Cal Tech testing said even though their investigation is not as complete as it could be, their preliminary findings are pretty conclusive.

"What we are seeing are buried debris," said McCollum,"we are not seeing any kind of sinkhole debris." 

They found chunks of cement, fencing wire, broken glass, pieces of metal and organic from decayed wood.

David Brown, who calls his company the sinkhole guys, the buried debris creates a void and settling over time.

"It is surface depression from the permeation of the years of the decomposing of the materials someone buried here," said Brown.

Brown said when the buried material breaks down they may create sinkhole like conditions, but they are not sinkholes; that's what the residents needed to know.

"I think they're clear here," said Brown," we do not have a sinkhole."

The solution is to excavate the debris and back fill the area with a truckload of dirt. The residents are giving it serious consideration.
