Document Description
The purpose of the project is to repair structural deficiencies and address bank erosion and scour along Big Chico Creek in the City of Chico. Without the repairs, the structural integrity of Vallombrosa Avenue and its associated pedestrian path may be threatened and lead to the closure of the road.
The City of Chico Public Works Department proposes to repair the erosion and fill in the cave on the west bank of Big Chico Creek using rock slope protection (RSP). The undercut cave will be collapsed and regraded to remove any safety risks to the public. A total of 187 linear feet of RSP will then be installed along the west bank to reinforce the reconstructed creek banks and prevent further erosion. All ground disturbing activities will take place within existing City right-of-way. (WDID 5A04CR00381)
