Location: The slide is located on Norris Canyon Road approximately 70 feet west of Milepost 0.83 in the San Ramon area (Figure 1). 2. Project Description: The purpose of the project is to repair a slide undermining the roadway and to reconstruct the roadway embankment. Construction of an access ramp allows excavation of the site and requires the removal of a section of fence, which will be reinstalled. Construction of a gabion wall stabilizes the bank and the placement of ungrouted rock slope protection on the slope further minimizes erosion potential(Figure 2). The ungrouted rock slope protection will be filled with soil and seeded and the access ramp seeded. On the slope just below the roadway,an existing outfall pipe protrudes approximately eight feet over the slide area (Figure 2). To minimize erosion, the pipe will be replaced with approximately 24 linear feet of drainage pipe. Placement of the drainage pipe will occur under the rock slope protection on the slope, exiting behind the top section of the proposed gabion wall (Figure 2). 3.
