The current five-year inventory of Bulloch County public school facilities does not qualify the district for any new schools. But local officials are ready to apply for $900,000 from the state to put a new roof on Stilson Elementary School and replace heating and air-conditioning systems at two schools. The Stilson roof will be one of the most expensive among 12 projects, predicted to cost $2.5 million, that the Board of Education agreed earlier this year to pursue from a list of school facilities needs identified by a countywide committee.
