SANTA CLARA – The San Francisco 49ers’ management company owes Santa Clara about $310,000 less than originally estimated for city staff time spent on Levi’s Stadium events, a final audit released Monday shows.

“This is only a portion of what has happened,” Gillmor said Monday. “We need to change the way we do business so this doesn’t happen again. This audit was the first step and we have more work to do — we need all the documents to fully know where we are.”

A draft released in May found the team’s management company owed Santa Clara $424,349 for police and firefighter staff time for stadium events from October 2014 to June 2016. But the final audit pared that back to $114,781 after some costs were reimbursed prior to the audit.

Gillmor, who once supported Levi’s Stadium and the team, pushed for the audit soon after she was appointed mayor in Feb. 2016. Gillmor suspected the city spent taxpayer dollars on the stadium in violation of Measure J, a 2010 ballot measure that established framework for the construction and operation of Levi’s Stadium.

The Santa Clara City Council in June 2016 approved a contract with Harvey M. Rose to conduct the audit.

Gillmor says she isn’t sure how the reduction in staff costs happened. Lead auditor Fred Brousseau couldn’t immediately be reached on Monday.

Top 49ers’ officials celebrated a victory, saying the auditor’s report “has already been proven to be riddled with errors.”

“They were forced to admit major errors and make significant changes to the draft report they previously leaked in a failed attempt to embarrass the 49ers,” said team president Al Guido. “In the end, they wasted over $200,000 in public funds to discover that the city of Santa Clara failed to bill $115,000 in expenses — something which was their responsibility.”

Guido said Gillmor’s plan to “create media headlines” backfired.

Santa Clara city officials also disputed the initial $424,349 estimate. Santa Clara’s acting finance director, Angela Kraetsch, questioned why Harvey Rose used estimates and “not actual amounts” and said most of those staff costs were paid in June.

But the final audit maintained some key findings from the draft report. Auditors found that $894,228 in public safety costs were paid by “construction fund” monies — left over because Levi’s construction costs were below budget. Team officials said the expenditure was approved by city leaders, but Gillmor says public safety is not an allowable use of those funds.

“The left over money in the construction fund could be been used to pay our mortgage on Levi’s Stadium,” said Gillmor, adding that she’ll demand that the Niners pay that back. Team officials countered that Levi’s construction fund money can’t be used for mortgage payments.

The audit also found the team’s management company hasn’t paid $718,803 to Santa Clara for allowing cars to park on a city golf course for five months. The golf course was one of five city-owned sites used for stadium event parking.

Team officials are disputing the unpaid parking fees, saying the Niners actually overpaid by a million dollars. That issue is being hashed out by officials on both sides but could end up in court.

The final audit will be discussed Thursday at the city’s first Stadium Authority meeting. The Stadium Authority, which is comprised of Gillmor and the other City Council members, is a separate public body which owns Levi’s Stadium and has leased it to the Niners.

Gillmor said she plans to hire a separate Stadium Authority manager to add another layer of scrutiny and will request another audit of stadium finances — based on a civil grand jury recommendation — going back to 2010.
