Measure J, the $574 million construction bond for the North Orange County Community College District, is winning by just 15 votes, according to the latest election results.

Orange County election officials certified vote totals last week, but a portion of the college district stretches into Los Angeles County, with those vote results yet to be certified.

L.A. County officials said they will certify the election totals Friday. They believe all of votes have been counted, but will spend the next few days canvasing precincts to ensure there are no outstanding ballots.

Measure J, which would be Orange County’s second-largest bond measure ever approved, would pay for upgrades and repairs at Cypress and Fullerton colleges. The measure has received 84,780 votes in favor across both counties, and 69,338 votes opposed. It needs 55 percent to pass.

About 4,000 votes were cast in L.A. County.
