Document Description
The Loma Prieta Road Emergency Washout Repair Project serves to repair the access road to public safety infrastructure located on the top of Loma Prieta Mountain. The parcel has a repeater vault and tower that supports 7 CAL FIRE repeaters plus additional public safety repeaters for Caltrans, State Fish and Wildlife, OES and CHP. In addition to these critical public safety repeaters are numerous State Microwave Repeaters that support most of Central California for the state Public Safety System. Recent rainfall has washed out portions of the road underneath the road prism. The road has been determined to be unsafe for large truck traffic. Specifically, traffic for Propane and Powerline support trucks. Loss of power to this site would significantly impact Public Safety operations across the Central State. Repairs to this road is critical as it is anticipated that winter rains will cause additional soil loss and significantly increase the size of the road failure. The road repair would involve utilizing a JD-245 excavator to create a keyway at the base of the washout (approximately 30 ft tall x 18 ft wide x 45 ft long) to place large (30” diameter) boulders. Engineered fill will be placed behind the boulders up to the level of the road surface. Additionally, a failed culvert will be replaced just upslope. The fill would be compacted with one foot lifts and then capped with 3-inch or larger rock. The road would then be final graded with a Cat 13 grader. Brush removal may occur as needed to allow access and to complete repair work.
