RCPC presented the first in a series of articles examining whether soundwalls could be built along Highway 24 (SR 24) through Rockridge. The article outlined noise-level thresholds and CalTrans eligibility criteria for soundwall construction.
Highway 24 (SR 24) through Rockridge
RCPC presented the first in a series of articles examining whether soundwalls could be built along Highway 24 (SR 24) through Rockridge. The article outlined noise-level thresholds and CalTrans eligibility criteria for soundwall construction.
“Today, sections of SR 24 may be eligible for noise barriers if the sound level at nearby households reaches, or is predicted to reach, 65 dB or higher without a barrier, and a feasible sound wall is predicted to lower the noise level by at least 5 dB at a sufficient number of residences to make its construction cost effective.”2011_06 - Soundwalls in Rockridge? article, June 2011
