State Route 138 Curve Correction

The California Department of Transportation, District 8, is undertaking a drainage and streambed modification project along approximately half a mile of State Route 138 under a Lake and Streambed Alteration Agreement approved by the California Department of Fish and Wildlife. The project involves the removal of an existing culvert along with its headwalls, wingwalls, and cable railings, followed by the installation of a new drainage system featuring updated headwalls and cable railings. Concrete lining will be applied to an existing culvert, the streambed will be graded, and un-grouted rock slope protection will be installed to stabilize the area and manage water flow. These activities aim to improve drainage efficiency and infrastructure resilience while minimizing environmental impact. The project is governed by Fish and Game Code section 1602, ensuring compliance with state regulations for alterations to waterways. Key contacts for the project include Adam Compton, Branch Chief at Caltrans District 8, and Chris Briggs, Senior Environmental Scientist at the Department of Fish and Wildlife, who oversee coordination and environmental compliance. The project is forecasted with a posted date of May 29, 2026, and is located in California, with all activities confined to the SR-138 corridor. No set-aside or NAICS code has been specified, and the initiative is part of ongoing efforts to maintain and upgrade transportation infrastructure in alignment with environmental protection standards.
