Document Description
Phase 3 of the LSAP proposes landside levee improvements along approximately 8.4 miles of the RD 17 levee system in San Joaquin County, California, including portions of the San Joaquin River east levee, portions of the levee along the northerly bank of Walthall Slough, and the Dryland levee extending easterly from Walthall Slough to ~ South Airport Way, to meet applicable Federal and State design recommendations for levees protecting urban areas. Project objectives are to construct seepage berms, setback levees, and slurry cutoff walls where needed to increase the levee's resistance to underseepage and through-seepage; to provide seepage exit gradients of less than 0.5 at the water surface elevation associated with a flood event with a 0.01 annual exceedance probability; and to implement USACE levee vegetation management recommendations.
