It turns out the oft-quoted $200 million taxpayer-backed bond that brought the Raiders back to the East Bay in 1995 is going to end up costing $350 million.

It’s a debt that Oakland and Alameda County taxpayers will be paying off until 2025 — well after Raiders owner Mark Davis is enjoying his new digs in Las Vegas.

“It was a bad deal,” said Oakland City Council President Larry Reid, who was chief of staff for then-Mayor Elihu Harris in the 1990s when the city and county agreed to an expansion of the Coliseum to bring the Raiders back from Los Angeles. “The projections were off, but everyone was just caught up in the emotions of having the Raiders return.”

The original idea was to pay off the bond through the sale of personal seat licenses. However, the seat license sales never came close to hitting the mark, leaving taxpayers liable for the difference.

And although most accounts set the debt at $200 million, interest brought the bill to $350.4 million, said Scott McKibben, executive director of the Oakland Alameda County Coliseum Authority.

Even with repeated refinancings and the paying off of interest, Oakland and Alameda County taxpayers are still splitting a $13 million tab every year through 2025.

The high annual payout is one of the key reasons that Oakland Mayor Libby Schaaf and the county Board of Supervisors balked at using public money to finance a new Raiders stadium.

And it’s not just the stadium redo that isn’t completely paid for. The Coliseum authority still owes more than $68 million on 1990s renovations for Oracle Arena, about $7 million a year, which the Warriors now pay. But who pays off that debt when the Warriors leave for San Francisco hasn’t been decided. If it’s the city and county, their total tab on the Coliseum complex will be about $20 million annually.

“We’ll cross that bridge when we come to it,” Reid said.

There’s one last insult. As The Chronicle’s Kimberly Veklerov reported, the Coliseum authority actually loses money on game days when the Raiders are in town. If the team sticks around until its Las Vegas palace is ready in 2020, attendance in Oakland could well plunge — right along with the authority’s take.

McKibben figures total game-day losses could exceed $2 million a year if attendance drops even 10 to 15 percent.

“We are better off if they don’t play here, and that’s the bottom line,” McKibben said.

Strikeout: The head baseball coach at San Francisco’s Galileo high school has been put on administrative leave after he allegedly shouted out Chinese-sounding gibberish to mock an Asian American player.

“Mr. (Don) Papa is not coaching the Galileo baseball team,” Gentle Blythe, spokeswoman for the San Francisco Unified School District, said in an email.

Blythe said the district placed Papa on paid administrative leave March 15 “as a result of information that emerged in the course of the investigation” into the racially charged incident.

The alleged incident happened during a varsity game between Galileo and Lick-Wilmerding High School at Skyline College on Feb. 24.

Papa yelled out his remarks at a player who was standing on first base and appeared to be puzzled by the coach’s instructions. Nakia Kashima, father of another Galileo player, described it as “Ching, chong, something, something.” He reported it to school officials.

Papa, 66, has coached sports for 25 years at Galileo, where he is also a social studies teacher.

He has not responded to requests for comment. On his Facebook page, where he goes by the name Don Steven, Papa told a supporter on Friday, “Can’t comment now — but I have some fight.”

Albany woes: The Albany Unified School District has just notified parents that a second incident with hate-speech overtones has been uncovered this month at Albany High.

According to district Superintendent Val Williams, “administrators were notified that a group of seven ninth-graders had been engaging in Nazi salutes to each other when passing in the halls.”

Williams said the saluting had been going on for “several months.”

She said the vice principal immediately “brought these students into the office, determined what occurred, contacted their parents and took appropriate action.”

The revelation comes just a week after officials disclosed that police were investigating a group of students who had allegedly created an Instagram account targeting African American students and an African American staff member. One photo reportedly showed a black doll alongside images of a Ku Klux Klan member, a torch and a noose.

Over the weekend, some 300 parents, students and others rallied outside Albany High in a public show of resisting bullying and racism.

Emergency call: As if addicts shooting up in the stacks hasn’t been enough of a problem, the San Francisco Main Library has been dealing with a plumbing crisis since Friday that knocked out most of its public bathrooms.

Michelle Jeffers, a spokeswoman for the library, says crews working through the weekend pinpointed the trouble to a couple of faulty pumps connected to the sewage system that were replaced just two years ago. A pair of emergency replacements, costing $20,000, weren’t due to arrive until Wednesday.

In the meantime, the library has brought in portable toilets for the public on Fulton Street, to go along with a few toilets in the building that have been deemed safe.

It was a bit of an inconvenience when the library staff hosted 60 members of the California Library Association at a meeting Friday morning on the Main’s lower level. What happened when they got the call?

“We escorted them to the the staff restrooms on the sixth floor,” Jeffers said.

Incidentally, Jeffers says senior staffers dealing with the mess have dubbed themselves the “Stuff Happens Incident Team,” also known as ... well, you know.
