school districts; optimal square footage

SB 1816 sets a requirement for Arizona school districts: if their actual building space meets or exceeds 110% of a calculated "optimal" square footage based on student enrollment (including leased space for charter schools), they cannot hold bond elections for new bonds or changes to approved capital projects. The bill mandates annual calculations of this ratio by the state board, posting the results online and notifying districts and county officials when the ratio hits 110% or higher. This directly affects school districts with sufficient existing facilities, restricting their ability to seek voter approval for new bond funding. The key mechanism is using a specific enrollment-based formula to determine eligibility for bond elections, with the threshold set at 110% of optimal space.
