Site work, paving, outdoor lighting and renovation of a civil project in Calexico, California. Completed plans call for site work for a road / highway; for paving for a road / highway; for the renovation of a water / sewer project; water / sewer project; and for outdoor lighting for a road / highway.

The work shall be done in conformance to the City's final plans and specifications for the Project, which include four (4) major tasks: Installing a Trash Screen across the New River and building a structural concrete Diversion Structure for the New River at a point approximately 900 feet downstream from the US-Mexico International Boundary in Calexico. These tasks also entail: Construction of a temporary diversion channel and coffer dam to build the Diversion Structure and Trash Screen. Demolition work and site improvements including grading, erosion control, fencing and installation of two security gates, lighting, and construction of a new paved access road over an existing dirt road. Removal of an existing security screen that is across the New River, between 2nd Street and the International Boundary. Installing approximately 1.5 miles of a 72-inch underground fiberglass reinforced mortar pipe (FRM pipe) to convey via gravity polluted New River water from the Diversion Structure to a point just upstream of where the All-American Canal Siphon goes over the New River. This work also requires: Building an Energy Dissipater at the end of the 72-inch FRM pipe to prevent erosion of the New River channel at the outfall of the 72-inch FRM pipe. Construction of a small temporary coffer dam to build the Energy Dissipater. Construction of a Pump-back System to replace the polluted water in the river channel that flows adjacent to City neighborhoods with clean, treated wastewater from the Calexico Wastewater Treatment Plant (WWTP). The Pump-back System consists of a 5.0-million gallons per day sewage lift station and the installation of approximately 4,000 feet of a 16-inch Ductile Iron Pipe forcemain. Grading and erosion control of an area just above where the 72-inch FRM pipe outfalls into the River. The Engineers Cost Estimate puts the cost to build the Project at approximately thirty-four million, one hundred and ninety thousand, and five hundred and fifty-six dollars ($34,190,556). A summary of the bids along with a recommended bid may be presented to the City Council for its consideration of awarding the Projects construction contract at a Public Meeting, after the bids are received and evaluated, in December 2022, at 6:30 p.m. in the City Council Chambers, 608 Heber Avenue, Calexico, California.
