The Newport Beach City Council is set tonight to vote on a new amendment to an agreement that governs operations at John Wayne Airport.

The amendment maintains the airport’s curfew—no takeoffs are allowed after 10 p.m. and no arrivals after 11 p.m.—through 2035. It also increases the number of airport passengers allowed from 10.8 million a year now to 11.8 million in 2021 and between 12.2 million and 12.5 million after the year 2026.

City officials said they expect the amendment to pass.

“The vote tonight culminates a process begun nearly three years ago,” said Newport Beach Councilman Keith Curry. “We’re pleased with the results [of the process] and expect approval to be unanimous.”

He said the amendment – known as the new Amendment to the 1985 Settlement Agreement – allows for “reasonable airport use and protects the neighborhoods” near the airport.

Orange County Supervisors unanimously approved the amendment at the end of last month.

“When you want an extension … it requires respecting all the parties and I believe the proposed settlement extension strikes that balance,” said Supervisor John Moorlach, whose district includes John Wayne Airport.

JWA operates under a Settlement Agreement agreed to by the County of Orange, the City of Newport Beach, the Airport Working Group and Stop Polluting Our Newport.

After tonight’s vote the amendment goes to the U.S. District Court of California, Central Court, Western Division, in Los Angeles, for final acceptance.
