Opponents of moving an LAX runway further north were handed a defeat by the county Airport Land Use Commission, which approved plans to modernize LAX that included the reconfigured runway. Supporters charge that moving the northernmost runway further north by 260 feet would improve safety for planes landing and taxiing at the airport. Supporters counter that the reconfiguration would degrade the quality of life for Westchester residents and businesses that abut the airport. In contrast, Bob Hope Airport officials are considering demolishing their existing terminal to meet the same safety requirements. To wit, the Burbank-Glendale-Pasadena Airport Authority presented plans for a new 14-gate terminal this week.
