Document Description
Construct/excavate a tunnel by conventional mining (mechanical and drill and blast) methods to replace a portion of the Oakdale Irrigation District South Main Canal that has a high risk hazard due to potential rock fall from above. The upstream portal is located near the Two Mile Bar Recreation Area parking lot in Tuolumne County and continues south west for approximately 5,860 ft where it will tie back into the existing South Main Canal in Stanislaus County (APN 002-041-029) (between approximately 37,50,23.19"N, 121,38,23.12"W and 37,49',35.74"N, 121, 39'9.14"W). The cross-sectional area of the tunnel is horseshoe-shaped measuring 10.5 feet at the bottom, 14 feet high at the center and will be located 200 feet below ground surface. 2/3's of tunnel spoils will be used to fill in the old canal section to create a gated, emergency access road.
