Big Chico Creek Erosion Repair Project (Capital Project # 50497)

The City proposes to conduct erosion repair and bank stabilization at two bridge crossings over Big Chico Creek, Rose Avenue and Warner Street, and a third erosion repair site near the intersection of Manzanita and Vallombrosa in the City of Chico. Heavy flows from 2023 winter storms caused scouring along the banks from the abutments at Rose Avenue and Warner Street Bridges. At the Manzanita and Vallombrosa erosion repair site, the west bank of the creek has significant erosion at the base, creating a “cave” that is exposed during normal flows. Rock slope protection (RSP) will be placed along the areas of scour at all three locations to prevent further damage and reinforce the banks and structures to better withstand future storm events.
