NAPA RIVER

OPERATIONS AND MAINTENANCE

PROJECT LOCATION AND DESCRIPTION

The Napa River Channel is a shallow draft channel approximately 16 miles long, that is mainly used for light commercial and recreational navigation. The Channel extends from the City of Vallejo, which is located on San Pablo Bay, northward to the City of Napa. The Operations and Maintenance (O&M) schedule provides for a six-year cycle of maintenance dredging for the Channel to a depth of 15 feet Mean Lower Low Water (MLLW) from the Mare Island Strait Causeway to Asylum Slough (downstream portion) and 10 feet MLLW to the head of navigation at the Third Street Bridge in the City of Napa (upstream portion).  Between FY 98 when the channel was last dredged and FY 08, the controlling dept shoaled to 2 feet MLLW in the upstream channel affirming that the Channel is long overdue for dredging.

FY 16 AND FY 17 ACCOMPLISHMENTS (based on the availability of funds):

• Complete environmental coordination for next dredging episode.
• Conduct a condition survey of the channel and initiate environmental sampling and testing and preliminary engineering and design for maintenance dredging.
• Meet with the Non-Federal Sponsor (NFS) to discuss dredging priorities should additional funds become available.
