Project Description, Common Name (if any) and Location:Alhambra Valley Road Slipout A-Vaca
Creek, County File #CP 97-22 : The purpose of the proposed project is to repair a slide in the roadway
embankment that threatens to undermine the roadway. To stabilize the bank and minimize erosion, an
approximately 24 foot high by 40 foot long rock-filled gabion wall will be constructed and any damaged shoulder
will be replaced. A minor amount of guard rail will be reinstalled upon completion of the project and exposed
areas will be hydroseeded. A small amount of temporary and permanent right-of-way may need to be acquired.
Construction may require some oak and buckeye trees to be pruned and a few small buckeyes (approximately
6 " dbh or less) may need to be removed. Due to the density of the vegetation in this area, these small trees
are not considered a scenic resource. Project location: The project location is in a rural, unincorporated area
of central Contra Costa County. The slide is located on the south side of Alhambra Valley Road, in a rural
wooded area, at mile marker 5451.
