From the San Joaquin River Restoration Program – Work has started on the Reach O levee improvements! The project will improve seepage and stability requirements within two miles of Eastside Bypass levees to allow for higher Restoration Flows. Currently, the levee is constructed of sand or gravelly soils of higher permeability which can transmit water via seepage during high-water stages — potentially impacting adjacent lands. The project aims to reduce these impacts by installing cutoff walls to reduce levee seepage and underseepage as well as replacing six aged culverts with concrete reinforced pipe. (more).
