Document Description
The California Department of Transportation (Caltrans) is proposing to replace two cross-culverts to improve maintenance operations. The project is located in Tehama County on Highway 36 approximately 2.5 miles east of Mineral. The proposed culvert replacement will occur at Poastmile Marker (PM) 85.58 and 85.65. The culverts are in poor condition and can no longer be repaired. They are undersized and often become blocked with woody debris. As a result, water overflows the culvert inlet and causes erosion to the hillside and road banks along the highway. Furthermore, the existing inlets do not meet current design standards and are difficult to maintain. The project will replace each of the cross-culverts with an appropriately sized pipe designed to meet the specific needs at each location. The inlets will be replaced with new structures and relocated to meet current design standards. Paved shoulders will connect the existing edge of pavement of the new inlet structures. Limited staging will be available at a dirt pull out near the outlet of the culvert at PM 85.58. Additional staging for equipment and materials is available at a paved pullout just east of the project site at postmile 86.3. Replacing the culverts will require permits from the California Department of Fish and Game, Regional Water Quality Control Board and the Army Corps of Engineers. Caltrans is consulting with Lassen National Forest Service on this project. All work will take place within the existing right-of-way limits. No additional right-of-way is needed to complete the project. No biological or archaeological resources were identified to occur inside the limits of the project.
