20. Grading plans for the PG&E gas line relocation or PODs T-2, V, and W, whichever are first submitted, shall indicate the required 6 foot high sound attenuation berm along the Vallecitos Road/Highway 84 fight-of-way. Grading plans and cross-sections must indicate the relationship between the berm, the relocated PG&E gas line, the PG&E access road, and the lots in these PODs. No grading for the pipeline relocation shall occur in these areas until such time as the grading plans have met with the satisfaction of the City Engineer and Planning Director. The applicant must demonstrate that the berm meets the requirements for sound attenuation as indicated in the EIR mitigation measures, or as can otherwise be demonstrated. No sound walls shall be permitted to be constructed instead of the berm. WATER ~ERVICE 21. Prior to approval of a final map(s) for Phase II of the project, a full water-service study shall be performed and submitted for review and approval by the Director of Public Works. Additionally, tank size, type (concrete, steel, etc.) and installation and maintenance responsibilities shall be specifically indicated and shall be to the satisfaction of the City, the developer, and the water-service provider. The water system shall be designed to the satisfaction of the City Engineer to assure that all lots can be adequately served with the appropriate flows and water pressure sufficient for domestic use as well as for the required automatic fire sprinklers. 22. The developer shall comply with all water service improvement requirements to the satisfaction of the City Engineer, including, but not limited to, the following: a. The design of the water system shall ensure that for the individual water user the water pressure does not fall below 40 psi an average day, nor fall below 30 psi at the peak hour, nor fall below 20 psi with fire flow, as measured at the water meter. Prior to approval of a final map for any lots which require water service from the Phase II water reservoir, an hydraulic analysis of the water system model shall be submitted concurrently with final improvement plans for review and approval of the City Engineer. b. Where the static pressure exceeds 100 psi (i.e., at elevations below approximately 550 feet), ductile iron pipe water mains, saddles for service connections and Class 200 polyethylene services shall be used unless otherwise approved by the City Engineer. c. Pressure reductions valves (PRVs), shall be installed at the house to lower the water pressure to 80 psi at all homes where deemed necessary by the City Engineer. No PRVs shall be permitted at curbside. -4-
