ID-A Pipeline Fire Flow Improvements

ID-A Pipeline Fire Flow Improvements

The project is proposed to provide a service loop to existing customers of Rincon del Diablo Municipal Water District (District) in the eastern portion of the service area. Project implementation is proposed to supplement fire response and will replace and upsize approximately 900 linear feet of 8-inch diameter ACP water main in paved portions of Rancho del Sol Street, from Green Mountain Road to Rancho del Verde, with a 12-inch diameter water main. This pipeline will tie into the District’s water distribution system on the westerly end of the project at Green Mountain within an existing unpaved District easement that is adjacent to the paved street. The project includes approximately 5,900 linear feet of 8-inch Ductile Iron Pipe, which will be installed proceeding on Rancho del Verde to Summit Drive, then to Old San Pasqual Road and ending at a connection point at San Pasqual Trail. The project will not directly or indirectly impact native vegetation. Project implementation involves phased removal of an approximately 3-foot-wide strip of the existing paving in street right-of-way, trenching to a depth of approximately 6 feet below ground surface, removal of existing pipe, new pipe installation, and connections to the District’s existing water service system. A portion of the street will be used for materials staging during construction. Through street access and parcel access will remain open during construction. An encroachment permit from the County of San Diego is required for project implementation and the contractor will be responsible for implementing a storm water pollution prevention plan and an approved traffic control plan during construction. The surface of existing streets will be returned to pre-project conditions upon completion of construction. The project will not involve direct or indirect impacts on native vegetation. The project will not directly impact sensitive biological resources because work will occur within rights-of-way with high levels of existing traffic and in previously disturbed utility easements. A pre-construction nesting bird avoidance survey will be conducted prior to project construction according to plans and specifications for the project so that construction will not indirectly impact raptors, migratory birds, or special-status species. Plans and specifications for the project require a pre-construction nesting bird avoidance survey conducted prior to ground disturbance; therefore no impacts on the environment or sensitive biological resources will result from project implementation.
