OAKLAND — The Public Ethics Commission is still investigating possible lawbreaking in city officials’ use of luxury box tickets to Warriors, Raiders and A’s games.

But its report, issued this month, makes it clear there are plenty of problems inherent in how the city handles the thousands of game tickets its tenants at the Coliseum and Coliseum Arena provide every month.

The report calls for appointing a “ticket administrator” to supervise the distribution and accounting of thousands of top-tier tickets that too many officials seem to view not as city property but rather a perk of their jobs as public servants, according to the report.

Whether they ask for them or not, city council members, the mayor and other city officials get monthly distributions from a pool of 20 luxury box tickets to every Warriors game, 18 luxury box tickets to every Raiders and A’s game and 18 more field level tickets to A’s games.

Other city officials who are involved in negotiating leases at the two big sports facilities, such as the city administrator and city attorney, also receive tickets for “government purposes” such as overseeing and reviewing operations there. This situation “presents significant, inherent ethics concerns in the areas of conflicts of interest and self-dealing,” the report points out.

All told, the city has more than 10,000 tickets per year provided to it at no cost.

With the tickets comes a requirement that they be accounted for, using the city’s Form 802, to describe who got the tickets and why. From the mayor on down, the commission’s report said, there have been lapses in this reporting.

The commission found that at least a third of those tickets go completely unaccounted for, despite the city council 10 years ago adopting rules requiring that elected officials report the tickets as gifts.

State Fair Political Practices Commission laws mandate the reporting of any gifts worth $250 or more and forbid accepting those worth more than $470 from any single source.

Local teams’ recent successes have pushed the value of some individual tickets far beyond that threshold. Luxury box tickets to Warriors playoff games, for instance, can cost thousands of dollars.

The report said Mayor Libby Schaaf failed to report eight of 476 tickets her office received in 2015 and 2016.

“We take our reporting responsibility seriously. In the handful of instances where tickets appear to have been issued, but a use was not reported it is most likely that we either were not actually issued tickets for those events, or a scheduled event did not occur, as in the case of a unneeded playoff game or canceled concert for example,” Erica Derryck of the mayor’s office wrote in an email.

“As for the policy as a whole, the mayor does not sit on the Joint Powers Authority which manages the sports facilities and is responsible for negotiating contract terms that the Oakland City Council and the Alameda County Board of Supervisors approve, and therefore has no official role in setting the policy or in implementing it,” she wrote.

At the other end of the spectrum, city council members Larry Reid and Noel Gallo each provided no documentation on 1,156 tickets received in the same time period. Council member Desley Brooks failed to report 990 tickets, according to the report.

City council member at large Rebecca Kaplan, who was one of the city officials negotiating terms of the teams’ tenancy at city facilities, has recently called for the city to “monetize” those free tickets by not getting them at all, in exchange for higher rent payments.

Other cities have imposed limits on the number of events officials can attend using free tickets, the Ethics Commission report noted. It suggested similar limits on the number of times an official could claim to be doing an inspection.

“I think the most important thing to come from this is the set of recommendations,” council member Dan Kalb said in an interview. “I support putting those into place and even more: Campaign donors should be prohibited from receiving tickets, and if you get tickets, then you can’t give money.

“Those of us who followed the rules and tried to follow the rules as required, we give them to nonprofits, don’t use many of them, but if someone wants to know, it’s in the report,” he said.

Some of the nonprofits his office had given tickets to, he said, were able to auction them off for fundraising.

“I’m thrilled that we can do that,” Kalb said.

In a statement, Ethics Commission Executive Director Whitney Barazoto said the commission will be drafting a proposed redesign of the process to ensure that ticket distribution and use is for “legitimate public purposes and complies with state and local ethics laws.

“Our commission is committed to helping the city resolve these problems in order to ensure effective and ethical distribution and use of city tickets going forward. The commission also will address past use of tickets by officials once the ongoing investigation of activities from prior years has been completed,” she wrote in an email to this newspaper.
