In Brevard County -- school is back in session -- the primary election is just days away -- but come November voters will decide the fate of a half cent sales tax to fund large scale school improvements.

But with aging buildings and infrastructure -- school system leaders say the alternative is closing some of them down.

Indialantic's Deb Clark has two reasons to be concerned about the state of Brevard's school facilities; her fourth grader who attends Indialantic Elementary, and her seventh grader who goes to Hoover Middle School next door.

"Plumbling, roofs, air conditioning. These things have to be done," said Clark.

Especially at schools of this age; Hoover is 49 years old, and Indialantic is even older -- it was built 57 years ago.

Brevard schools has compiled a list of the nearly 100 schools and facilities deemed in need of repair and upgrades.

Most of the schools are at least forty years old. The 113,000 square foot Hoover Middle School needs improvements like air conditioning, water piping and electrical system renewals. Officials say it also needs exterior upgrades.

And that costs money.

Bring in the half-cent sales tax proposal which would last ten years.

"We just want our communities to understand the types of things, air conditioning, roofs, pipes, things that we really need to renew at every facility," said Brevard Schools Superintendent Dr. Brian Binggeli.

School system leaders say the tax would generate $33 million a year, and Clark says she fully supports the referendum. But it's not just because she has two children currently in school.

"You really have to look at what you are getting for this. It really raises the quality of life in our community. It affects all of us. I think it's worth it. I think it's a deal," added Clark.

Three Brevard schools were closed last year after voters rejected a half-cent sales tax referendum back in November of 2012.

School leaders say if it fails again, potentially six million dollars in cuts would take place -- and four schools are targeted for closure.

Orange County and Volusia County voters will also be voting on a half-cent sales tax for school improvements.
