The project proposes to maintenance dredge shoal areas to 35-foot depth in the Port of Richmond and maintain other channels at authorized depths; and to dispose of dredged material at Alcatraz. In Fiscal Year 1973, 1,226,000 cubic yards of material were dredged with 190,000 and 480,000 cubic yards projected for 1974 and 1975 respectively. There will be an increase in turbidity during dredging and disposal and displacement of benthic organisms. Resuspension of silt will possibly affect fishlife and plankton by increasing turbidities. Channels will continue to provide ship access to the Port of Richmond.
