PROJECT LOCATION AND Description

Located along the San Francisco Bay in Marin County, San Rafael Creek Channel is 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.
