EIS for San Francisco to Stockton Navigation Improvement Project Now Available

Published May 10, 2019

The Draft General Reevaluation Report (GRR) and Environmental Impact Statement (EIS) for the San Francisco Bay to Stockton Navigation Improvement Project, prepared by the U.S. Army Corps of Engineers, is available for public review. 

The study area is a 13.2 mile length of navigation channel spanning central San Francisco Bay to Avon just east of the Benicia-Martinez Bridge and includes the Pinole Shoal Channel, and the Bulls Head Reach portion of the Suisun Bay Channel.  Although the navigation channels in the study area are authorized to a depth of up to -45 feet mean lower low water (MLLW), the channels are currently maintained to only -35 feet MLLW.   The proposed project includes deepening the existing maintained channel depth of the Pinole Shoal Channel and Bulls Head Reach (Suisun Bay) from -35 feet to -38 feet MLLW, dredging a 2,600 foot sediment trap at Bulls Head Reach with a depth of -42 feet MLLW, plus 2 feet of overdepth, leveling the rock outcrop located to the west of Pinole Shoal from a peak of 39.7 feet MLLW to 43 feet MLLW, and using the dredged material at permitted beneficial reuse sites.

The Draft GRR/EIS is available for review on the Corps' environmental planning website at: http://www.saj.usace.army.mil/About/DivisionsOffices/Planning/EnvironmentalBranch/EnvironmentalDocuments.aspx
