Resolution No. PC-93-49 Page 6 a. The design of the water system shall insure that on a average day, the water pressure does not fall below 40 psi, at the peak hour the pressure doe not fall below 30 psi, and with fire flow the pressure d es not fall below 20 psi, all of which shall be measur d at the meter. A hydraulic analysis that models the wa er system shall be submitted for review and approval of the city Engineer with the submittal of the improveme t plans prior to final map approval. b. Where the static pressure exceeds 100 psi (elevations below approximately 550 feet), ducti e iron pipe water mains, saddles for service connecti ns and Class 200 polyethylene services shall be used unless otherwise approved by the city Engineer. c. Pressure reduction valves (PRVs) sha 1 be installed at the house to lower the water pressure to 80 psi, at all homes where deemed necessary. No PRVs hall be permitted at curbside. d. Piping between the water meter and the PRV shall be 1.5- inch minimum diameter and upgraded to chedule 80, or as determined by the Chief Building Off ic ' al, to accommodate the expected higher water pressures. A 1 service laterals between the main and the meter shall b 1.5 inch minimum diameter and shall be upgraded to accommodate the additional water pressure, as dete ined by the city Engineer. e. The applicant shall install a reduce pressure station near the intersection of A street and the EVA, if determined necessary by the City Engin er, such that the line in the EVA and "B" Court maybe a a lower pressure zone. f. The exact location of the Foothill road shall be approved prior to the submittal of the Foothill Road. water mains in he city Engineer ovement plan for g. The size of the water main in "A" stree Road and the EVA shall be approved by between Foothill he City Engineer. 17. Unless otherwise approved by the City Engin er the storm drain line on "A" street near the intersection of Foothill Road shall not dump into the drainage swale but shall continue to Foothill Road and tie directly into the s orm drain culvert crossing Foothill Road. The final storm d ainage design for the area shown as the drain swale along th east side of "B" Court shall be subject to review and app oval by the City Engineer prior to approval of the final map. The final design may include piped storm drainage systems r storm drainage swales.
