AI Contract Overview

The California Department of Transportation is preparing to rehabilitate 17 culvert systems comprising 30 segments along Interstate 5 in Shasta County, between post miles 56.70 and 66.50, using state and federal funds. The work aims to repair, replace, or upsize deteriorated culverts affected by corrosion, abrasion, joint separation, and deformation, which compromise structural integrity and hydraulic function. These deficiencies, particularly in smaller-diameter culverts, increase maintenance demands and threaten roadway stability if left unaddressed. The project will employ trenchless technology, cut-and-cover methods, concrete repairs, and liner installations to restore functionality and enhance resilience against future flow increases linked to climate change. Construction will involve temporary construction easements and four permanent drainage easements, with staging areas located at PM 61.70 and PM 64.59. Approximately 5.33 acres of soil will be disturbed, requiring clearing, grubbing, and limited tree removal, with excavation depths reaching up to 60 feet for trenchless installations. Lane closures will be implemented as needed, and all nearby utilities will be preserved in place. The project is scheduled for completion within a single construction season, requiring approximately 210 working days. No borrow or disposal sites are anticipated, as all excess soil and debris will become the contractor’s property. Consultation has been conducted with relevant agencies, tribes, and stakeholders, and the project requires permits from the Army Corps of Engineers under a Nationwide Permit, Regional Water Quality Control Board Section 401 certification, and a California Department of Fish and Wildlife Section 1602 Agreement. The initiative aligns with broader efforts to safeguard infrastructure reliability and environmental compliance, with Jana Marquardt of Caltrans District 2 serving as the primary point of contact. The project was posted as a forecast on June 30, 2026, under the title Flume Creek Leftovers Project.

Full Description

The California Department of Transportation (Caltrans), using State and Federal funding, is proposing to rehabilitate 17 culvert systems (30 culvert segments) on Interstate 5 in Shasta County. The proposed project occurs between post miles (PMs) 56.70 and 66.50. The purpose of this project is to repair, replace, and upsize culverts where necessary. The project would re-establish the structural integrity needed to maintain and protect the highway and meet the hydraulic demands, including potential future flow increases due to climate change. The project would restore the culverts to a good condition. The project is needed because the culverts within the project limits exhibit corrosion, abrasion, joint separation, alignment, and shape deformation deficiencies. Smaller diameter culverts are more difficult to inspect and maintain, requiring more frequent cleaning to keep the drainage openings clear. If not improved, the condition of the culverts will continue to deteriorate, impacting hydraulic capacity and threatening the integrity of the soil and pipe structure necessary to support the roadway. Culvert replacement would be accomplished through trenchless, cut and cover, concrete/joint repairs, and liner installation. Approximately 5.33 acres of soil would be disturbed during project implementation. The maximum anticipated excavation depths for the project are associated with cut and cover and trenchless culvert installations (estimated at 20 and 60 feet, respectively). Tree removal is anticipated. Clearing and grubbing would be required. Project construction would be staged and would utilize lane closures as needed. Right-of-Way The proposed culvert improvements would require temporary construction easements. Further, the acquisition of four permanent drainage easements is anticipated. Staging Staging areas have been identified at PMs 61.70 and 64.59. Disposal/Borrow Sites Excess soil material and construction debris would become the property of the contractor. As such, no borrow or disposal sites are anticipated. Utilities All utilities in proximity to the locations of work would be protected in-place; no utility conflicts are anticipated. Schedule The work would be completed in one construction season and would require approximately 210 working days to complete. Consultation/Coordination Caltrans performed a records review, field surveys, and consultation/coordination with applicable agencies, tribes, and individuals. Permits Based on the current scope, the project would be subject to following resource agency permits. Army Corps of Engineers Nationwide Permit (Section 404 permit- non-reporting) Regional Water Quality Control Board Water Quality Certification (Section 401 permit) California Department of Fish and Wildlife Lake and Streambed Alteration Agreement (Section 1602 Agreement)
