The problem area is right in front of Deltona High School, on Howland Boulevard, between Wolf Pack Run and Forest Edge Drive.

"Sinkholes are very unpredictable," explained Volusia County Engineer Gerald Brinton. "We know there's a very large void down there."

Volusia County engineers are trying to prevent what they say could turn into a catastrophe on Howland Boulevard.

"It could be a circular void down there," admonished Brinton, "it could take an l and take off the the side [and] there's no way to know."

The sinkhole was discovered 154 feet below the surface, on Monday.

However, engineers have not yet been able to determine its width.

Friday morning, crews began drilling holes on the road to find out just how big this thing actually is. They'll fill the holes with grout.

"He's set up to go 10 to 12 hours a day continuously; he's expected to go seven days at a minimum."

The sinkhole is located right in front of Deltona High School, one of the largest campuses in the county. Many of its nearly 3,000 students drive to school, and pass directly over the problem area.

The Principal says it's a blessing in disguise that engineers discovered the problem when they did.

"The fact that this is the last day before our winter break is great, remarked Principal Gary Marks, "it really worked out well for us." He added, "a couple of weeks ago, or after we return it would probably create an ongoing traffic problem in front of the school."

According to the county engineer, it usually takes between 15 and 20 days to repair sinkholes like the one found in front of the high school.

He said he's confident it will be fixed by the time the students return to class on January 3rd.
