The item, which was continued to next week at the request of Supervisor Don Knabe, would force LAWA to comply with a 2006 settlement that required it to redistribute air traffic throughout the region to airports such as L.A./Ontario International Airport.
Despite the delay, supervisors on Tuesday heard from Frank Lopez, a public policy manager for the Los Angeles Area Chamber of Commerce, who urged them to proceed cautiously.
Lopez asked that supervisors deal separately with Los Angeles International Airport's improvement plans and the efforts to redistribute air traffic.
"Do not delay the modernization plans," he told the board.
If Knabe's motion moves forward, it would direct William Fujioka, the county's chief executive officer, to meet with officials from the city, LAWA and the county's Airport Land Use Commission as well as enforce compliance with the settlement agreement that stems from expansion plans at LAX.
The county's counsel would also be asked to review the settlement and report back in 30 days on whether LAWA and Los Angeles have abided by the terms of the agreement.
The settlement called for LAWA to take substantive steps to reduce environmental impacts near LAX by encouraging passenger and cargo expansion at the Ontario airport and L.A./Palmdale Regional Airport.
LAWA operates LAX as well as the Ontario, Palmdale and Van Nuys airports. The agency reports to the city of Los Angeles.
The item was introduced at the Feb. 12 meeting but was moved into closed session. It was later announced the item had been continued to this week.
At the Feb. 12 meeting, the board also heard from several residents and employees of LAX about their concerns over the modernization plans and the possible economic and environmental effects.
