Document Description
Caltrans proposes replace an undersized 88-foot long, 3-foot diameter culvert with a 9-foot diameter culvert. The culvert conveys Timber Gulch flows under State Route 1. The undersized culvert is causing debris collection at the inlet thereby restricting downstream flow. As a result of the restricting flow, extensive scouring and erosion has occurred at the inlet. The new culvert will be installed using the pipe ramming technique which requires the use of an insertion pit and receiving pit. The pit will be excavated as necessary to achieve a depth of 4 feet.
