Document Description
Caltrans proposes to repair the storm damaged northbound embankment of SR 101, located at PM 9.0 in Sonoma County near the City of Petaluma, approx 1.4 miles north of Old Redwood Hwy and just north of the southbound on ramp from Pepper Rd. This project will repair 3 small landslides on the northbound embankment. The slides will be repaired by re-grading the existing northbound side slope to 2 to 1 or flatter, re-grading an existing top of bank v-ditch, and lining the v-ditch with concrete to make it a trap-gutter. In addition, an existing 12" corrugated steel pipe downdrain will be replaced. All of the work will be within the existing Caltrans ROW.
