A majority of Contra Costa County voters, but just slightly over the required two-thirds threshold, were in favor of maintaining the county's participation in the state's vehicle abatement program, as of the most recent ballot count from the primary election.

In the latest data from the county elections office, last updated on Friday, 67.40% of counted ballots were in favor of the measure, with 32.60% opposing it. The current tally has Yes on Measure G at just over above the necessary 66.67% majority vote needed to pass.

However, the small margin that had made it too close to call on Election Night -- with Yes at 68.74% -- did shrink as additional eligible ballots were processed in the ensuing days, down to less than 0.75% from the deciding threshold.

As of Friday, there were an estimated 2,000 ballots remaining to be counted in Contra Costa County, which is about 0.9% of the total 221,856 votes cast on the measure. Basically all pending ballots, if that number is slightly higher than 2,000, would need to be in the No camp in order to flip the outcome, mathematically.

If final certified results -- due by July 7 -- remain above the required 66.67% threshold for the measure to pass, Contra Costa will be among the counties in the state set to continue participation in the California Highway Patrol abandoned vehicle abatement program, which is aimed at removing "abandoned vehicles that create a public nuisance and a health or safety hazard," according to the CHP.

If Measure G failed to reach or exceed two-thirds support from county voters in the final results, the local Vehicle Abatement Services Authority -- which facilitates the vehicle abatement program and is funded by an additional $1 registration fee for most vehicles in the county -- would "cease to operate and be discontinued," according to the authority's staff.

The county has participated in the abandoned vehicle abatement program since 1981, with Measure G coming to voters as the final step in a 10-year renewal process. The program's services have been implemented and overseen by the Vehicle Abatement Services Authority since all of the county's cities voted to enter into it in 1991.

The required two-thirds supermajority vote or higher comes following the passage and implementation of Proposition 26 by California voters in 2010. Under that legislation, "special taxes" such as those collected for the vehicle abatement program must be passed by two-thirds or more of voters in an election.
