 | Danville residents living near Crow Canyon Road can expect to get some relief from traffic noise generated by the busy arterial street as crews begin the installation of sound walls along the north side of Crow Canyon Road, near the Crow Canyon Country Club residential development.
The first phase of the project will include the pruning or removal of trees in conflict with the proposed wall. Town officials say they are working to limit the number of trees that will need to be pruned or removed. Of the 98 trees located directly adjacent to the sound wall study area, 21 are in conflict with the proposed walls, and will need to be removed.
The removal of these trees will allow the other existing trees to flourish, and will reduce maintenance problems associated with the existing trees, a release stated. The tree removal work is expected to take place this month, prior to the start of the annual bird nesting season. New trees will be placed along the corridor to compensate for the removal of the impacted trees. Construction of the new walls is expected to take place in spring and summer of 2013.
Following build-out plans for the Dougherty Valley in the early 1990s, which would use sound walls as noise mitigation, the town of Danville conducted engineering studies, a geotechnical investigation and an arborist report. Based on these studies, the town determined the key locations for sound walls along Crow Canyon between El Capitan Drive and St. George Road to reduce noise levels.
Funding for this project is provided by construction fees collected from the Dougherty Valley development and is expected to be completed in late summer or early fall of 2013.

Posted by LMP, a resident of the Danville neighborhood, on Jan 11, 2013 at 6:56 am I think I'd rather have the trees and a little traffic noise than a big wall.

Posted by MCL, a resident of the San Ramon neighborhood, on Jan 15, 2013 at 7:02 am They don't really work. Something has to absorb the sound, the walls merely cause the sound to ricochet, and even can make it worse. When they walled the 680 corridor one friend living a couple blocks away (in San Ramon) stated that it was even noisier after they were installed.

Posted by JT, a resident of the Danville neighborhood, on Jan 15, 2013 at 3:17 pm More stupidity. It might be a "sound" wall, meaning it is constructed soundly, but it could be better described as a rebound wall.
Idiot planners need to look for sound absorption walls! and not pretend that concrete, brick and otherwise do anything to absorb sound.
How can our society be so DUMB!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Posted by peggy, a resident of the Alamo neighborhood, on Jan 16, 2013 at 5:33 pm Sound walls help those who need it most: those living nearest the traffic. If you were living with the noise, you would have a different opinion than those who just drive by and miss the trees. Get real.
