After some residents have complained that noise from Orange Line buses is keeping them awake at night – and annoying them during the day – the MTA announced Friday it will be install sound-mitigation measures at a handful of locations along the 14-mile route. Metropolitan Transportation Authority officials said they surveyed 41 homes whose residents had complained and found that nine exceeded noise levels established by the project’s initial environmental review and were eligible for mitigation. “I absolutely hear it. It definitely sounds like we’re at a truck stop on the freeway,” said Lisa Cerda, a member of the Tarzana Neighborhood Council. “We do hear the braking, the stopping, its coming and its going. It’s worse when you’re outside. We actually play games with the kids: Can you tell which way the bus was going?” The agency plans to work with the residents and property owners of the 32 other sites to see if adjustments can be made to lower the impact, even though the MTA has no requirement to do so. Already the MTA has shifted the buses’ rooftop exhaust to point away from homes. But Cerda said they never surveyed her yard, and she questions the methods used to measure noise. Buses run from 4 a.m. to 1 a.m. most nights and buses come every five or six minutes during rush hour – a boon for commuters who’ve come to rely on frequent service, but a hassle for residents. The MTA had gone to great lengths to prevent noise when it was planning the busway, putting up soundwalls across the San Fernando Valley and using rubberized asphalt in some locations to keep sound down. The buses run on compressed natural gas, not diesel engines. “None of us have had any decent sleep since September,” said Stephanie Sheppard, a 10-year resident of a multi-unit apartment complex in Van Nuys, referring to the time when practice buses started running. “It is loud, continuous noise. It is disruptive. It’s hard to concentrate…. You just sort of get some quiet, then another bus comes.” Lisa Mascaro, (818) 713-3761 [email protected] 160Want local news?Sign up for the Localist and stay informed Something went wrong.

The MTA could not immediately provide its budget for the work. “We knew there would be some cases where we would exceed our cumulative noise threshold and we would have to mitigate,” said MTA spokesman Marc Littman. “There are thousands of people who live along the alignment. We’re trying to be good neighbors. Where we have complaints, we respond to each one of them. Where we exceed criteria, we’re dealing with it.” Shortly after the $350 million Orange Line opened on Oct. 31, the MTA began taking sound readings to determine if neighbors were getting exposed to too much noise. Littman said improvements will be made at five apartment buildings and four single-family homes.
