Port of Redwood City - Geology and Hydrology

Geology and Hydrology

The Port of Redwood City is situated on the east banks of Redwood Creek approximately one kilometer upchannel from the mouth of Redwood Creek. Extensive areas of marshland and bay muds are found in the vicinity of the Port. Westpoint Slough joins Redwood Creek from the southeast about 600 meters north of the Port of Redwood City. Deepwater Slough is a U-shaped channel whose two ends join Redwood Creek both north and south of the Port, with both joins on the opposite site of Redwood Creek. Approximately one kilometer north of the Port of Redwood City, Corkscrew Slough enters Redwood Creek from the northwest. From that confluence northward the northwest bank of Redwood Creek (now at the mouth) consists of Bair Island, an expansive area of saltwater marsh and salt evaporation ponds.

Typical high tides at the Port range from 7.0 to 8.4 feet (2.6 m), based upon February, 2007 tide chart data. Low tide typically varies from -0.8 to 2.9 feet (0.88 m).
