Lower San Joaquin River Feasibility Study

Lower San Joaquin River Feasibility Study

The Corps and its non-Federal sponsors propose to improve flood risk management to North and Central Stockton by repairing and enhancing the levees that surround the city, and by constructing and operating closure structures on Fourteenmile Slough and Smith Canal. The overall study area as defined in the Study authorization includes the mainstem of the San Joaquin River from the Mariposa Bypass downstream to the city of Stockton. The study area also includes the distributary channel of the San Joaquin River in the southernmost reaches of the Delta: Paradise Cut and Old River as far north as Tracy Boulevard and Middle River as far north as Victoria Canal. Based on availability of potential non-Federal sponsors the refined study area focused on approximately 305 sf encompassing incorporated areas of Stockton, Lathrop, and Manteca as well as unincorporated portions of San Joaquin County. The draft FR/EIS/EIS presents the draft findings of the Feasibility Study, which formulates and evaluates the benefits, costs, and environmental effects of alternative plans to improve flood risk management in and near the cities of Stockton, Manteca, and Lathrop in San Joaquin Valley.
