CASTLEWOOD, S.D.(KWAT)–Castlewood School District residents go to the polls Tuesday to decide a $6 million bond issue.

Castlewood was rocked by a tornado in May of last year that tore school facilities apart.

Superintendent Peter Books tells KWAT News that through a $5.6 million insurance settlement, they’ve made repairs to what could be fixed, but the insurance money didn’t cover everything the school district wanted to do in terms of improvements.

Tuesday’s $6 million bond referendum needs 60-percent voter approval in order to pass.

Books says if that happens, a portion of the money will be used to construct an auxiliary gymnasium, and newer and bigger classrooms.

Voting is Tuesday from 7 am to 7 pm at the Castlewood Community Center.
