A long stagnant proposal to build a single car rental facility shared by multiple companies at Los Angeles International Airport will be studied again in the next three years under a plan likely to be approved Monday by the Board of Airport Commissioners.

The plan calls for the airport to build the facility in Manchester Square, a once densely populated neighborhood east of the airport that has in recent years become more of a ghost town. City leaders have long had grand plans for the neighborhood — since 1998, the airport has bought up most of the real estate in the roughly 20-square-block area — but there have been few concrete plans about what to do with it.

After the 9/11 terrorist attack, then-Mayor James Hahn wanted to build a sprawling passenger check-in building there, a move that would effectively ban cars from the Central Terminal Area, possibly making the airport’s core safer, at least from car bombs. But the idea was not considered viable.

By now, Los Angeles World Airports has purchased most — but not all — of the homes and multifamily residences in the neighborhood. Presumably, if they move ahead with the rental car facility, the airport operator will buy out the remaining tenants.

Manchester Square is bordered by Century Boulevard on the south, Aviation Boulevard on the west, Arbor Vitae Street on the north and La Cienega Boulevard on the east.

Under the plan expected to be approved Monday, Kansas City, Mo.-based TranSystems Corp. will receive about $3 million to study building the car rental facility. Many other airports, including Phoenix Sky Harbor and Chicago Midway, have centrally located rental buildings, in which many companies share one garage. Eventually, L.A.’s facility likely would be linked to the Central Terminal Area with an automated train. If built, in 20 years it might also be linked via the same automated system to Metro’s Green and LAX/Crenshaw lines.

Airport officials refer to the project as the ConRAC, for consolidated rental agency complex.

“The TranSystems consultant team will complete a report detailing the findings and recommendations regarding the layout of the ConRAC, descriptions for main building components, sizing of the facility based on future estimated demand, traffic circulation within Manchester Square, and traffic patterns to and from the ConRAC and the freeway network,” airport staff wrote in a report to the board.

TranSystems is expected to have a report ready for the board later this year.

LAX already has a mechanism to pay for the facility. Since 2002, it has been collecting a $10 fee on every customer renting from an LAX-based car rental brand. According to the report prepared for the board, there is now more than $160 million available to fund a new car rental center.
