Creek Restoration along Zone 5 Line D between Cherry Street and Union Pacific Railroad in Newark, Alameda County
NOE - Notice of Exemption
The project involves restoring approximately 2,700 ft. long section of Zone 5 Line D to a more natural state by constructing a meandering low flow channel within a wider flood plain and planting native riparian vegetation. Existing gravel access road on westerly side of channel will be reconstructed to provide adequate vehicular access for maintenance. A 20-ft. wide prefabricated bridge would be installed across restored channel near the downstream limit of the project to provide maintenance vehicle access and a crossing location for the Alameda County Water District domestic water supply pipelines. Existing drainage outfalls to channel would be modified to conform to the restored channel alignment. Existing rock riprap will be salvaged and reused in the project to secure the toe of slope. Purpose of this project is to restore constructed channel to a more natural meandering creek with increased habitat values, minimize potential of future embankment instability, and reduce maintenance over time while providing flood protection. Restored channel will become an added feature to the Ohlone College environmental education program.
