Casa Loma Siphon No. 1 and San Jacinto Pipeline Protection Project

The Casa Loma Siphon No. 1 and San Jacinto Pipeline Protection Project involves encasing approximately 320 feet of the CRA Casa Loma Siphon No. 1 Pipeline and 295 feet of the San Jacinto Pipeline with reinforced concrete to prevent flotation and exposure, with steel rebar installed both horizontally and vertically to ensure structural integrity. The project will not add new aboveground components or alter existing operational and maintenance conditions at the site. Work is scheduled to occur in San Jacinto, California, with a defined performance period from October 1, 2026, to February 15, 2028, broken into phases for vegetation removal, site preparation, excavation, infrastructure installation, and final site restoration. All contractor activities must comply with stringent environmental and regulatory requirements, including the implementation of a site-specific Stormwater Pollution Prevention Plan, adherence to California Air Resources Board emissions standards, use of certified low-emission equipment, and prohibition of non-biodegradable erosion control products. Equipment must be decontaminated and certified clean at project entry and exit points to prevent the spread of invasive species, soil, or vegetative matter, meeting standards aligned with USDA Forest Service guidelines and local air quality regulations. Noise control measures are mandated, requiring the use of mufflered equipment, adherence to local noise thresholds, and obtaining necessary variances. Contractors are also required to enact a rideshare plan for personnel and coordinate with landowners to avoid disruption to domestic animals. All submissions must be provided in two paper copies and one PDF electronic copy, and environmental documentation such as the SWPPP, species occurrence reports, site photographs, and floral compendium are referenced as attachments supporting regulatory compliance. The project is forecasted under the NAICS code 237120 by the Metropolitan Water District of Southern California, with environmental specialist Alfredo Aguirre designated as the point of contact; however, no contract value, pricing structure, payment details, or formal award evaluation factors are specified in the available information.
