Fresh from voter approval of an $18 million-a-year parcel tax extension to help keep its doors open, City College trustees are now looking to go back to voters next November with a whopping $800 million facilities bond.

“With some of our buildings, it’s questionable if they could withstand an earthquake,” college Trustee John Rizzo said. “You would be appalled at the condition of some of the buildings we are trying to teach in — they are well beyond their designed age.”

And it looks like the voters agree.

A Tulchin Research poll the district commissioned found 77 percent voter support for a new facilities bond — well above the 55 percent support required — with the respondents not appearing to care whether the ask was for $450 million or $800 million.

So the district is preparing to go for the full load.

Still, competition for votes could be steep, as there are likely to be competing measures on next year’s ballot seeking money. District officials expect to descend on City Hall this week to gauge the temperature of Mayor London Breed and the Board of Supervisors.
