Lower Norco Bluffs Toe Protection   8

Lower Norco Bluffs Toe Protection

The project consists of an earth fill placed against the existing bluffs, approximately 7,330 feet in length, revetted with riprap slope protection and a launchable stone toe blanket. The project will tie into existing high ground at the upstream (Station 90+20) and downstream (Station 19+90) project extents. The embankment fill will raise the grade between 12 and 25 feet above existing grade to provide protection up to a 100-year flow event water surface elevation (WSE). The proposed embankment slope is 2H:1V and is revetted with riprap slope protection 42 inches thick measured perpendicular to the slope face. Expected scour is between 5 and 14 feet below the existing thalweg (between 6 and 19 feet below existing grade at the project alignment). To eliminate the need for dewatering, excavation is planned down to 2 feet above typical groundwater averaging 5 feet below existing grade. A launchable stone toe is intended to provide some protection from scour. The launchable stone toe is 9 feet high and varies in width, between 10 and 30 feet, depending on the expected scour depth along the project alignment.
