Gold Hill Road Over Auburn Ravine Bridge Replacement Project
MND - Mitigated Negative Declaration
Present Land Use
Placer County Zone Designation: Farming - Building Site with 4.6 acre minimum size (F-B X 4.6 AC. Minimum.)
The proposed improvements include the replacement of the existing bridge. The proposed bridge will be approximately 92 feet long and will be supported on seat type abutments. The abutments will be located behind the existing abutments and will be placed outside the limits of the Ordinary High Water Mark. Excavation depth at the abutments will be up to 20 feet, measured from the existing roadway surface. The Gold Hill Road bridge profile will be raised to provide hydraulic clearance required for the design hydrologic event. The roadway alignment will remain at relatively the same location as the existing roadway alignment. The roadway approaches would be widened from 20 feet to 32 feet wide and raised by a maximum of approximately eight feet to conform to the replacement structure.
