The proposed project consists of the abandonment of approximately 17,500 linear feet of existing 12- to 24 inch-diameter concrete-lined steel potable water pipeline within the City of Escondido and unincorporated County of San Diego. The pipelines would be replaced with approximately 12,600 lf of new pipe generally ranging between 12 and 24 inches in diameter and comprising steel, ductile iron, polyvinylchloride (PVC), or high-density polyethylene (HDPE) pipe material, as well as PVC or copper service laterals off the main lines. An approximately 5-foot-long section of 30-inch-diameter pipe would provide a connection point near the Oak Hill Memorial Park (Cemetery) entrance. New meters also would be constructed and, in some cases, existing meters would be relocated. The project would include construction of an approximately 2,545-foot-long, 20 inch-diameter HDPE recycled water pipeline which would not be activated until some point in the future. The project also would include construction of an approximately 10-by-20-foot pressure-reducing structure. The project would replace aging potable water transmission and distribution infrastructure, increase water delivery capacity and pressure to the project area, and maintain a reliable water supply and distribution system. The primary objective of the increase in pressure or capacity that could result from the proposed project is to improve the flow of water to existing property owners during a wildfire-related emergency. The existing pipelines would stay in service throughout the duration of construction, and would be capped and abandoned in place following implementation of the proposed replacement pipelines, or removed if necessary to provide room for the replacement lines.
