Three Hempstead High Schools were closed Tuesday due to plumbing and heating issues, much to the surprise of some students who arrived there earlier this morning.

Some parents say they were never informed about the issues at Hempstead High School, Prospect Elementary and Front Street Elementary School that kept the buildings closed.

News 12 obtained some photos from inside the high schools from the community group “Hempstead for Hempstead.” They appear to show water pooling near a staircase. The group says this is unacceptable and claims it could have been prevented.

"Parents were never informed ahead of time and that is a major health and safety concern,” says Carmen Ayala. “It is a failure of the superintendent and the person who is the acting head of facilities from securing the building."

Some Prospect School parents posted on social media that they were, in fact, warned ahead of time that pipes burst inside the school. One post read that "Prospect School have been calling since Saturday to inform the parents."

District Deputy Superintendent Varleton McDonald would only say that they were “in the process of repairing all of the issues that have occurred."

District officials say robocalls went to all parents as soon as the problems were discovered. They expect both Hempstead High School and Front Street School to reopen Wednesday, but Prospect will not be open. They say maintenance is still working to address all issues.
