Document Description
Reconstruction of a stormwater drainage system ofn State Route 395, in Modoc County, in the community of Likely. The existing drainage system, which consists of a series of paved and unpaved gutters and subsurface culverts parallel to the east side of the roadway, now longer functions properly due to landscape and ditch modifications. Storms sometimes result in flooding of residences and businesses adjacent to the highway.
The proposed project entails reconstruction of paved and unpaved gutters, construction of three drainage inlets and a 24-inch diameter subsurface culvert syst, structure within an existing irrigation canal. The outlet structureswill consist of a 24-inch diameter pipe witha flared-end section and rock slope protection to dissipate flows. Drainage inlets will include concrete vaults (sand traps) which will trap heavier solids, such as sand and cinders, that may be present in storm water runoff. The sand traps will include clean-out access for routine miantenance.
