State Route 41/Culvert Installation and Drainage Project [KP 11.3/12.7 (PM 6.9/7.9)]
NEG - Negative Declaration
Present Land Use
Caltrans proposes to rehabilitate the drainage at two culvert locations between the Friant-Madera Canal and the State Route 41/145 intersection in Madera County. The proposed work includes modifying surface water drainage and replacing the existing culvert at post mile 6.9. The drainage channel would be modified at the existing culvert at post mile 7.9. Drainage channel excavation would be a maximum depth of two feet (0.61 meters) at the culvert opening; the channel would then gradually slope away from the culverts and level off with the existing streambed elevation. The purpose of the project is to alleviate flooding of the roadway that occurs during heavy rains.
