Resolution No. PC-95-12 Page 7 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. d. piping between the water meter and PRV shall be 1.5- inch minimum diameter and upgraded to Schedule 80 to accommodate the expected higher water pressures, or as otherwise determined by the Chief Building Official. All service laterals between the main and the meter shall be 1.5-inch minimum diameter and shall be upgraded to accommodate the additional water pressure, as determined necessary by the city Engineer. e. If determined by the City Engineer, a reduced pressure station(s) shall be installed such that certain tracts may be served at a lower pressure zone. 23. Prior to the approval of any final map for PODs R, V, and W, access to the water reservoir shall be identified. To the greatest extent possible, the applicant shall attempt to acquire a 20 foot wide access easement over or adjacent to the relocated PG&E gas line access road from the Vallecitos Road entry, along the backs of lots in POD W, and through the Tiger Salamander Habitat. The City's access easement must be paved to a width of 14 feet, or as otherwise determined by the City Engineer. This road shall be gated to prevent unauthorized access to the water reservoir and Tiger Salamander Habitat. The exact location and design of the road shall be subject to approval by the city Engineer and Planning Director. 24. Prior to the approval of any tentative map for PODs V or W, staff, PG&E, and the applicant shall work out the location and design of the PG&E/water reservoir access road at the Vallecitos Road entrance.
