The Los Angeles County Airport Land Use Commission has ruled that the Los Angeles International Airport (LAX) Master Plan Alternative D violates the county Comprehensive Land Use Plan of 1991.

The ruling means that Los Angeles Mayor Jim Hahn needs ten Los Angeles City Council votes to get his LAX master plan alternative approved, rather than eight of 15 City Council votes.

Members of the county Airport Land Use Commission unanimously said that the LAX master plan is inconsistent with the County Airport Land Use Plan.

RESOLUTION FINDINGS — The county panel claims that a direct conflict exists because the LAX plan results in negative noise and safety impacts on a significantly different population than was assumed when the county land use plan was adopted years ago.

The county commission claims that key changes to the airport proposed in the LAX master plan that impact surrounding neighborhoods, creating compatibility issues, include:

– changes to north runway alignment for an outer runway (6L/24R) and an inner runway (6R/24L); and

– new plans for south runways — the outer 7R/25L runway and the inner 7L/25R runway.

Runway reconstruction and extensions would shift noise impacts to newly exposed neighborhoods, the commission claims.

The commission also charges that by expanding the airport into Manchester Square, a former residential area, and other areas, LAX officials are changing the airport boundary.

A proposed remote parking, ground transportation center, consolidated rental car facility and other proposed facilities are not within the airport boundary in the county land use plan, the county commission says.

The county commission also says that the existing three-story Centinela Hospital Airport Medical Clinic, at 9601 Sepulveda Blvd., would be included — and impacted — in the LAX master plan runway protection zone with reconstruction of Runway 24L.

The commission claims that there is a conflict because the existing clinic currently brings the general public into an area that the new LAX master plan considers to be a “runway protection zone clear of people.”

The proposed LAX plan says the medical clinic would either be removed, relocated or renovated, but doesn’t specify which will occur, the commission complains.

A cluster of commercial and industrial buildings at the south edge of the runway protection zone of Runway 24L would also be included inside a new runway protection zone if the LAX plan is approved, the commission warns.

The LAX plan calls for Runway 24L to be extended eastward and positioned further south.

Most of the buildings within this cluster are owned by the Los Angeles Community College District and are used as a movie prop training and storage facility.

Another building is under private ownership and is used a valet car park facility.

The LAX master plan proposes purchase of these locations during Phase I, in the fourth quarter of 2006 through the third quarter 2008. The LAX plan calls for the structures to be relocated prior to any shift in the runway protection zone.

As the LAX master plan creates shifts in runway alignments, corresponding noise shifts in noise contours will occur, the county commission charges.

The Airport Land Use Commission claims that a comparison of the 1991 noise contour and the proposed 2015 noise contour indicates that three public schools, two elementary schools and one high school, with a combined enrollment of 3,835, and three private schools and pre-schools would be subject to greater noise levels than the county land use plan identified.

In addition to the schools, there are 12 other noise-sensitive uses — ten churches, one hospital and one park — within this area, the county commission says.

That means a significant number of additional people and homes would be affected.
