Document Description
The County proposes to develop a uniform channel section supporting Austin Road Bridge with scour countermeasures to prevent channel degradation of South Littlejohn's Creek. The proposed project will include the following actions: clearing and grubbing along the creek banks; installation of a temporary access ramp and coffer dams, or alternative diversion methods, to access the creek channel during construction while the creek is flowing; excavation of the existing earthen channel bottom and banks to an approximate depth of 4.5 feet; placement of a layer of Caltrans Light Class Rock Slope Protection (RSP) in the excavated channel bottom to conform to the upstream and downstream conditions with staggered concrete baffles to hold the RSP in place; and potential placement of RSP in the form of riprap along the embankment to reduce depths of excavation.
