Document Description
The Metropolitan Water District of Southern California (Metropolitan) is proposing to repair and reconstruct the access road and pad adjacent to the San Francisquito Canyon Blow-off Structure. The access road and pad experienced significant erosion during 2004-2005 winter storm high flows in the San Francisquito Creek. Part of the main flow of the creek shifted from the west side to the east side of the structure, completely washing-out access to the structure. Metropolitan is proposing to install a temporary water-filled diversion structure to divert any flows during the repairs. The repair/reconstruction would entail placement of approximately 2-feet of fill, which will be protected from future erosion by a rock-filled gabion reno mattress. The road would be regraded and topped with a crushed aggregate base.
