Fixing leaky roofs could cost an additional $7.5 million. That list has 18 projects at 14 sites. An extra $4.3 million is needed for 19 distinct life, health and safety improvements. That work includes districtwide security upgrades and asbestos management, remediation of basement leaks at nine schools, and miscellaneous structural issues at several other schools.

Kranz also included a contingency fund of $3.5 million, or about 10 percent of expected costs, because some of the estimates were based on facilities reports that date back as far as 2002.

Bathroom renovations, window replacements, painting and parking lot improvements are also needed across the city but were not factored into this request.

“I’m not going to sit here tonight and say the sky is falling,” Kranz said. “But we have systems that are getting harder and harder to maintain, and we’re running out of optional space.”

The school system has not had a coordinated, scheduled approach to building maintenance in recent memory, and it has struggled to pay for what little work has been done.

This year’s $7 million allocation for capital needs is the largest in years, up from the less than $1 million last year. Of that, $1 million is committed to buying school buses, leaving $6 million for school projects.
