California Department of Transportation, District 7
Rock Slope Restoration Project
CON - Early Consultation
Present Land Use
Caltrans is proposing to construct 2 secant walls submerged underground on the southbound/coastal side of SR 1 (Pacific Coast Hwy) at PM 4.0 and 4.2 to stabilize the roadway foundation. The secant wall at PM 4.0 is proposed at 601 feet long and 40 feet high. The second secant wall at PM 4.2 is proposed at 202 feet long and 40 feet high. The purpose of this project is to perform permanent restoration of damage incurred by severe storm events within the project limits. The slope has sustained severe surf erosion that has undermined the roadway and high intensity storms have resulted in cracks and displacement of the roadway shoulders. The project is needed because the area is prone to erosion and needs adequate slope protection.
