Oklahoma State Regents for Higher Education told legislators that the state’s campuses have almost $1.5 billion worth of leaky roofs, worn out heating and air conditioning, bad wiring, environmental hazards, chipped paint and buildings that need to be updated or demolished. According to the regents’ report, some campuses spend up to 30% of their annual budgets on maintenance and repairs. The need isn’t entirely with buildings approaching 100 years old.
