AI Contract Overview

Caltrans plans to rehabilitate a 72-inch corrugated steel pipe culvert at Postmile 29.6 on Interstate 15 near Temescal Valley in Riverside County using concrete invert paving as the primary method. The work will be accessed from the inlet on De Palma Road, utilizing a Traffic Control System with Reversible Control, and no temporary access roads are needed—all equipment will remain on the shoulder. The goal is preventive maintenance to preserve the drainage system and extend the culvert’s service life by halting further deterioration and avoiding more costly future replacement. Limited activities will occur near both the inlet and outlet, including sediment removal from the last 50 feet inside the culvert, installation of a temporary gravel bag berm, and creation of a six-foot-wide walkway by cutting back vegetation without removing roots. Minor clearing and grubbing will take place around the inlet and outlet for fire safety during welding. Shoulder closures on I-15 will support culvert marker replacement and temporary drainage inlet protection, with public information and enhanced enforcement measures in place. The project uses only state funding and requires a temporary encroachment permit from Riverside County for work on previously state-purchased land that was relinquished to the county. The estimated duration is 50 working days for a culvert that spans approximately 440 feet.

Full Description

Caltrans proposes to rehabilitate an existing 72-inch Corrugated Steel Pipe (CSP) culvert at Postmile (PM) 29.6 on Interstate 15 (I-15), near Temescal Valley in Riverside County. The proposed rehabilitation method is concrete invert paving. Construction activities will primarily be performed from the inlet located on De Palma Road, where a Traffic Control System with Reversible Control will be implemented. No temporary access roads are required. All equipment and vehicles will be parked on the shoulder. Vehicles and equipment will not be traveling to and from the culvert work area. This project is funded by State-only funding. The purpose of this project is to perform preventive maintenance on the existing culvert to preserve the drainage system and extend its service life. The need of this project is to delay or prevent further deterioration of the culvert and to postpone the need for more extensive rehabilitation or replacement in the future. Limited work will occur in the channel near the outlet to implement best management practices (BMPs), including installing a temporary gravel bag berm and removing sediment from the last 50 feet inside the culvert. Additional limited work will occur in the channel near the inlet to establish a ~6-foot-wide walkway for the construction crew to access the work site. To establish this walkway, plants and bushes will be cut while leaving the roots in the soil. Minor clearing and grubbing will also occur in front of the inlet and outlet for fire prevention related to welding operations. On I-15 Northbound and Southbound, shoulder closures will be implemented to replace the culvert markers and install Temporary Drainage Inlet Protection. Traffic Management Plan (TMP) Elements include Traffic Management Plan-Public Information and Construction Zone Enhanced Enforcement Program (COZEEP). Per Right-of-Way Engineering, there are impacted areas on this culvert project along De Palma Road that were purchased by the State and subsequently relinquished to the County of Riverside. As a result, a request for an encroachment permit will be submitted to the County of Riverside. The Encroachment Permit will be temporary and valid only during the construction period. The estimated construction duration is 50 working days, and the total culvert length is approximately 440 feet.
