Document Description
The proposed action would be to place 1,520 feet of rock and tree revetment on the west side of the Sacramento River and remove gravel on the east side of the river. The primary objective of placing longitudinal stone toe with tree revetment is to stabilize the site, thereby protecting the M&T Chico Ranch/Llano Seco Rancho pumping facility and the outfall for the City of Chico's Wastewater Treatment Plant. Approximately 9,120 tons of rock would be placed to about half of the bank height to an elevation of about 120 feet above mean sea level and the base of the revetment would be about 30 feet in width. Backfilling behind the stone toe will thicken the tow and provide a medium for revegetation. The top of the bench would be an average of approximately 10 feet. Woody brush material would be incorporated into the revetment by anchoring the material with cables and partially sunken large boulders to prevent loss during overtopping flows. The brush portion of the revetment would consist of multiple, alternative clusters of trees spaced approximately 10 to 15 feet apart at two elevations to provide instream and object cover at a range of flows.
