San Ramon Creek Emergency Stabilization

Cal Engineering & Geology provided emergency design and engineering services during construction of federally-funded repairs of a creek bank that failed during the New Years Eve floods of 2005-2006 and threatened a single family residence situated on top of the bank. High flows in San Ramon Creek had completely scoured the creek bank created a hole approximately 24 feet deep, undermining a segment of existing sheet pile revetment located below the home. Emergency repair measures were needed to stabilize the site and save the house. The repair included the placement of more than 400 tons of rip rap to protect the toe of the existing sheet pile wall and installation of 100 feet of new sheet pile wall with helical anchor tiebacks.
