DRA F T P18-0078, P18-0080, P18-0081, PUD-130, and Tract 8569 PC-2026-09, April 22, 2026 18 of 36 52. STORM WATER ENERGY DISSIPATION. The drainage design relies on storm discharges onto unprotected natural hillside slopes. To reduce erosion potential, the storm drain system shall be designed to dissipate energy and reduce flow velocity to less than 6 feet-per-second at the discharge end of all outfalls. (Address this condition prior to improvement plan approval). 53. PRIVATE STORM DRAIN EASEMENTS. Private storm drain easements shall be granted across the western portion of Lot 30 for the benefit of Lot 29 and Parcel C, and across Lot 29 for the benefit of Parcel C. The easements shall assure that storm runoff within Devany Creek can flow unobstructed across these properties to the Dublin Canyon Road culvert. Maintenance of the creek shall be the obligation of each property owner, unless this obligation is transferred to the homeowner’s association. (Address this condition prior to subdivision map approval). 54. POTABLE WATER. The potable water distribution system within the subdivision shall be designed in accordance with the Hydraulic Analysis prepared by Akel Engineering Group dated June 2024, specifically “Alternative 3 – Moller 770 Connection”, although Lots 29 and 30 shall be connected to the Dublin Canyon Pressure Zone. Said system shall be publicly owned and maintained by the City. Appropriate Public Service Easements shall be granted across roads and access pathways to allow maintenance access to these facilities. (Address this condition prior to subdivision map approval). The City’s Utility Division requires a water inter-tie on Dublin Canyon Road between the Dublin Canyon Pressure Zone and the Moller 770 Pressure Zone so the subdivision can be temporarily fed from the Dublin Canyon zone if service from the Moller zone is interrupted. Final design and coordination of the inter-tie is subject to the Utility Division review and comment during the permitting phase. (Address this condition prior to plan approval). 55. DESIGN STANDARDS: All permanent connections to the City’s potable water network shall conform to Pleasanton Municipal Code §14.04.050. Any required water pressure and/or flow needed by the project developer beyond that available from the network at the point-of-connection must be provided by the project developer as a private improvement on the customer side of the meter or backflow prevention device. All extensions or upgrades to the potable water network shall be designed to satisfy the following minimum standards: a. Minimum number of valves: i. 3 at cross intersections ii. 2 at “T” intersections iii. 500 feet maximum spacing iv. 1 valve at each fire hydrant lateral
