Julianne Robinson will return to Deltona High School as a junior next month.

But she and her friends are worried about a sinkhole that opened up on campus at the Volusia County school.

"I have lots of friends who I go over for sleep-overs and their parents are concerned, too, because it's a huge issue," Robinson said. "It's scary that it's a dangerous situation that we all have to go into."

Volusia County Schools officials identified the sinkhole in June while students were on summer break. Repairs continued Monday, as the Aug. 18 first day of school gets closer.

Music students will likely have classes in the auditorium when school starts Aug. 18.

Nancy Wait, the spokeswoman for Volusia County Schools, said the School Board approved about $400,000 for repairs and to stabilize the building housing the chorus and band programs. Work will probably continue through September. So far, workers have placed 24 of 41 pilings to shore up the music building. They plan to line the edges with concrete, and then fill in the rest.

The sinkhole is only under one building, Wait said, adding that students will not be permitted inside that building and the entire area around the building is fenced in.

"Its a serious thing — sinkholes in Florida," said Cristobal Romero, the grandfather of three Deltona High School students. "I mean, I've seen in the news, it's dangerous. I think children should not be allowed to go there."

Lois Karlovich remembers when a 163-foot sinkhole opened up on Howland Boulevard, adjacent to Deltona High School.

"What's that saying about that area?" Karlovich said. "It's unstable, and I would just not be comfortable with my grandchildren going back to school."

Robinson added: "It's nerve-racking to know that if you get too close to a building, it could fall."

Romero said students should be transferred to another high school. Both Romero and Karlovich recognize other schools would likely then be overcrowded. But it would also mean students are safe.

School officials said student safety is the No. 1 priority.
