Book Description
The purpose of this report is to recommend for construction, a plan of improvements for the Central San Francisco Bay segment of the John F. Baldwin Ship Channel. This project is part of the San Francisco Bay to Stockton Project authorized by Congress in 1965. The San Francisco District, U.S. Army Corps of Engineers is the responsible agency for the construction of the John F. Baldwin Ship Channel. The Sacramento District, U.S. Army Corps of Engineers is the responsible agency for the construction of the Avon to Stockton Ship Channel. Advanced engineering and design and construction of the John F. Baldwin Ship Channel is proceeding in three phases. Phase I was constructed in 1974 and consists of a main ship Channel 55 feet deep and 2000 feet wide across the San Francisco Bay. Phase II, the subject of this report, provides channel improvements in Central San Francisco Bay near Richmond, California. Phase III provides for channel improvements in San Pablo Bay, Carquinez Strait and Suisun bay to Point Edith. The impetus for channel improvements in Central San Francisco Bay is the worldwide trend toward larger tankers with correspondingly deeper drafts, to transport crude petroleum and a progressive increase in the demand for crude petroleum.

Book Description
The WES Research Ship Simulator was used to evaluate the design of Phase II of the John F. Baldwin Ship Channel and to study the impact of the deepened channel on the navigability of large tankers inbound to the Long Wharf docking facility near Richmond Harbor. The present channel and maneuvering area is 35 ft deep and is inadequate for the larger tankers bringing crude oil from the Alaskan North Slope. The San Francisco District has proposed to deepen the channel to 45 ft deep. The authorized 35-ft-deep channel was simulated to verify the ship simulator setup as well as establish the base maneuvering strategies, and the proposed 45-ft-deep channel was simulated to study the proposed conditions. In addition to the tankers, containerships navigating into Richmond Harbor entrance channel were also simulated to investigate the impact of channel deepening on other ships using the maneuvering area. Originator-supplied keywords: Channels (Hydraulic engineering), Harbors--California--San Francisco, John F. Baldwin Navigation Channel (Calif.). Ships--Maneuverability--Simulation methods, Tankers.

Book Description
This report describes testing and evaluation performed by the Environmental Laboratory of the U.S. Army Engineer Waterways Experiment Station (WES) on sediment from the John F. Baldwin Ship Channel, California. Test protocols from the Corps' Management Strategy for Disposal of Dredged Material were used in the present evaluation to determine the potential for migration of contaminants into the effluent, surface runoff, leachates, plants, and animals at an undetermined upland disposal site. Two composite sediment samples were collected from the Pinole Shoal and West Richmond reaches of the J.F. Baldwin Ship Channel from core depths to 47 ft (or 15.7 m) (45 ft project depth plus 2 ft overdepth. Collected sediments were transported to WES for testing ...

Book Description
In August of 1990, the battelle/Marine Sciences Laboratory (MSL) conducted a program of sampling, geologic characterization, and chemical analysis of sediments from five sites in the West Richmond reach of the John F. Baldwin Ship Channel in San Francisco Bay. Additional sediment samples were collected for the USACE Waterways Experiment Station (WES) Wetlands and Uplands testing programs. The objective of the MSL study of the five West Richmond sites was to determine the physical characteristics and chemical contaminant levels in sediments proposed for dredging. Metals concentrations were comparable to or lower than those reported in the Phase 1 study. Butyltin concentrations were very low, and organic contaminants (PAH, PCB and pesticides) were not detected. Differences between Phase 1 and Phase 2 results may be explained by the fact that Phase 2 stations are outside the shipping channel. 16 refs., 4 figs., 16 tabs.
