Document Type
NOE - Notice of Exemption
Document Description
The California Department of Transportation (Caltrans) proposes immediately replacing the triple-barrel culvert system on State Route (SR) 4 at post mile 36.6 in San Joaquin County. On 12/31/2022 a high-intensity rainstorm passed through Farmington and overwhelmed the three culvert pipes, eroded the embankment slope, jeopardized the guardrail, and undermined the shoulder and westbound travel lane. A State of Emeregncy was declared by Governor Newsome on 01/04/2023. The scope of work includes replacing the three existing, damaged, 36” Corrugated Steel Pipes (CSP) and steel Flared End Sections (FES) with three new 36” CSPs and steel FESs. The project will also stabilize the embankment and roadway structure, replace damaged guardrail, and place Hot Mix Asphalt. The purpose of this project is to immediately rectify structural and drainage damages caused by the extreme storm event. The project is needed to prevent the loss or impairment of life, property, or essential public services.
