Title

Swarthout Canyon Washout Repair

Description

Issuance of a Clean Water Act Section 401 Water Quality Standards Certification for a pipeline cover repair. The pipeline is a petroleum line which lies within a perennial stream tributary to Cajon Wash in Lone Pine Canyon. The pipeline has been exposed. The area surrounding the pipeline will be excavated and a geotube installed around the line. The line will be covered with flexible concrete matting. A portion of an adjacent bank will be armored with grouted rip-rap to prevent further erosion. 0.08 acres of the wash will be affected by the armoring. An access road will need to be constructed from Swarthout Canyon Road to the project site affecting 0.8 acres of uplands. A 0.43 acre staging area will be cleared in the adjacent uplands.
