BPD found this story about problems with Cohen Stadium: Cohen Stadium in danger of failing inspection code
Some $175,000 of renovations and improvements need to be done at Cohen Stadium in order for it to pass its next building code inspection, city engineers said Wednesday.

Appearing before City Council, City Engineer Alan Shubert said it was imperative for the panel to approve funding so the stadium could remain in compliance.

Most of the problems are with the electrical and plumbing systems throughout the facility, Shubert said. There are wiring problems such as exposed cables and leaking sewage lines, he said.

"It's not an eminent situation that would require us shutting the facility down. There are just things we have to address to make sure those kinds of safety issues don't occur," he said.

Shubert said most of the major repair work will be done by March or April of next year, in time for baseball season.
For the record, Cohen Stadium was built in 1990 and home of the original double-A Diablos. The problems appear to all be for the city to repair since it's leased, not owned, by the club.
