Document Description
Install a rip rap revetment along approximately 100 feet of the Corte Madera creek bank in order to replace existing creek stabilization efforts that area currently undermined. The revetment will extend approximately 10 ft. up from the toe of the existing bank, and will be constructed using 0.25 and 0.5 ton boulders. The revetment is intended to re-establish the natural slope of the creek bank and help resist future scour and bank destabilization.
