Resolution No. PC-95-55 Page l3 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. 39. The portion of the water main from the reservoir to the street shall be ductile iron unless otherwise approved by the City Engineer. This line shall be cathodic protected if located adjacent to the PG&E gas main and if so determined by the City Engineer and/or PG&E. 40. With submittal of the first final map of PODs 0, R, V, or W, the final improvement plans for the tract shall include detailed landscape and irrigation plans for vegetative screening around the second water reservoir. Landscape material shall be consistent with other native, drought- and deer-resistant materials consistent with the Ruby Hill Master Landscape Plan, and shall be subject to the review and approval of the Planning Director and City Landscape Architect. Fencing materials also shall be indicated, subject to the review and approval of the Planning Director and City Engineer. Landscaping and improvements shall be completed prior to acceptance of the tract improvements of the first final map of POD o.
