Rattlesnake Reservoir Fencing Project

The Rattlesnake Reservoir Fencing Project is a security upgrade initiative managed by the Irvine Ranch Water District located in Irvine, Orange County, California. The project aims to address ongoing security breaches at the Rattlesnake Reservoir, an uncovered facility containing recycled water intended for industrial and commercial use. The scope of work includes the construction of 3,900 linear feet of 6-foot high, black vinyl-coated chain link fencing, with 1,400 feet to be installed on the north side of the reservoir and 2,500 feet on the south side. Additionally, the project requires the replacement of two existing fence gates with new 6-foot high chain link gates. All new security structures will be installed on the existing site to serve the same purpose as the current infrastructure, and the contractor will be responsible for restoring any disturbed pavement and landscaping upon completion. The project is located at the IRWD Rattlesnake Reservoir (APN 104-118-02) and has been granted a Notice of Exemption from the California Environmental Quality Act under Class 2 and Class 3 categorical exemptions, as the work involves replacement and limited new construction without significant expansion. While specific contract values, pricing schedules, and evaluation factors are not provided in the available documentation, the project is categorized under NAICS code 237990. Administrative oversight and environmental compliance are managed by Emily Le, an Environmental Compliance Analyst for the Irvine Ranch Water District. The project documentation was officially filed with the Orange County Clerk-Recorder in November 2025.
