The state school building authority approved a financial plan Tuesday that might eventually allow for a new $75 million Hurricane Middle School. The plan indicates the School Building Authority would pick up one third of the cost. The SBA still has to sign off on the project which would require roughly half the agency’s school construction budget for the entire fiscal year. A virtual vote on Monday would clear the way for the county school board to send a bond issue to November voters that would replace the 1950s era school and improve athletic facilities at six other schools. The county has already purchased a 22-acre site next to Hurricane High School for the new middle school. The SBA’s next meeting is scheduled for Sept. 16.
