PUD-138 and VTM 8616 Planning Commission Page 15 of 30 needs. (Address this condition during construction) (PROJECT SPECIFIC CONDITION) 52. WATER & SEWER SYSTEM EVALUATION: The City commissioned a Happy Valley Water & Sewer Study by RMC dated 11-21-2016 which evaluated the residual capacity of the installed potable water and sanitary sewer networks to serve properties within the Happy Valley Specific Plan. The study focused on properties that had not been annexed. a. For water capacity, Section 3 “Water System Evaluation” of the report concluded that the City’s existing water distribution system has sufficient capacity to meet the City’s criteria for minimum pressures, maximum velocity, and allowable headloss, although the report did not model the distribution system. The City subsequently commissioned a City-wide water system computer model currently under development by Akel Engineering Group. Since the RMC report did not model the distribution system, the applicant shall fund the creation of a scenario within the Akel computer model to determine whether distribution system upgrades are needed based on the applicant’s expected water demand. The City’s Operations Services Department will lead this effort once funding is submitted. (Address this condition prior to improvement plan approval) b. For sewer capacity, Section 4 “Sewer System Evaluation” of the report concluded that there is sufficient capacity available in the trunk sewer downstream of the Sunol Boulevard connection. The report assumed, however, that the force main pipe in Alisal Street extending from Pump Station S-14 along the applicant’s Parcel A frontage to Sycamore Road was 6-inches in diameter. The existing force main is currently 4-inches in diameter. The applicant shall evaluate through computational analysis the need for a 6-inch diameter force main using the RMC report’s assumptions together with the subdivision’s expected effluent discharge to Pump Station S-14. This analysis shall be submitted to the City’s Operations Services Department for review and approval. If the City determines a need to upgrade the force main pipe, then the applicant shall implement this improvement. The design and construction cost of the upgrade will be eligible for fee credits against the Happy Valley Specific Plan Sanitary Sewer Main Pro-Rata Share Fees that would otherwise be collected. (Address this condition prior to improvement plan approval) (PROJECT SPECIFIC CONDITION) 53. WATER SERVICE: The Happy Valley Specific Plan, Chapter VII “Public Facilities”, Section A “Water”, subsection 1 “Specific Plan Water System Concept”, includes the following requirement: “The City shall construct and front the cost of constructing all water facilities required for the Golf Course and Golf Course housing in accordance with a future agreement to be entered into between the City and the Golf Course property owners. The owners of existing
