Document Description
The San Joaquin Area Flood Control Agency (SJAFCA) is currently evaluating the Lower Calaveras River levee system to demonstrate that the levees meet or exceed the Federal Emergency management Agency (FEMA) criteria for providing 100-year flood protection. Geotechnical analyses indicate that a short section of the north bank of the Lower Calaveras River at the Bianchi Road Undercrossing of El Dorado Street as potential seepage and stability issues. At this location there is an elevation difference between the levee landside tow and the 100-year water surface elevation of approximately 15 feet and the landside levee slope is relatively steep (1.5 horizontal: 1 vertical) To address this issue, SJAFCA is proposing to install a drain at the landside toe of the levee to mitigate the seepage and stability issues. The toe drain will be installed approximately five feet deep, at the toe of the levee directly adjacent to Bianchi Road along the roadside shoulder. No trees or vegetation is present along the shoulder, therefore no trees or vegetation will need to be removed to facilitate the toe drain installation.
