SAN RAFAEL CREEK
OPERATIONS AND MAINTENANCE

 
 

PROJECT LOCATION AND DESCRIPTION

San Rafael Creek is located north of San Francisco Bay in Marin County. Project Operations and Maintenance (O&M) is in a shallow draft channel used mainly for light commercial and recreational activities. The O&M schedule provides for a seven-year cycle for maintenance dredging to a depth of -8 feet Mean Lower Low Water (MLLW) for the Across-the-Flats Channel in San Francisco Bay to the mouth of San Rafael Creek, and a four-year cycle for maintenance dredging to a depth of -6 feet MLLW for the Inner Canal Channel to the head of navigation at the Grand Street Bridge in the City of San Rafael. The Inner Canal and Across-the-Flats Channels were last dredged in FY 12 to a depth of -5 feet MLLW, with placement of the dredged material at the San Pablo Bay Disposal Site (SF-10), an unconfined aquatic disposal site.

ISSUES AND OTHER INFORMATION

  • The City of San Rafael is the NFS.
  • The NFS must cost-share for upland disposal containment of any material unsuitable for unconfined aquatic disposal. Originally the NFS provided an upland site for the Inner Canal portion of the project, but that site is no longer available.
  • The NFS is now required to cost‑share 20% of the tipping fee for upland disposal of dredged material.
