BACKGROUND
The November 2025 storms caused a small landslide that undermined about 33 linear feet of the roadway edge, leaving part of the asphalt concrete road unsupported and creating a steep drop down to a private driveway. To ensure the future stability of the road and provide public safety, staff propose to repair the damage by installing a new rock slope protection (RSP) buttress to stabilize the downhill shoulder of 4620 Redwood Road at a 1:1 slope, about ten feet high, averaging five feet in thickness. Following installation of the RSP, about 100 feet of the damaged road surface will be reconstructed or repaved.
