PC-2026-16 June 24, 2026 and signed by a California-licensed civil engineer. (Fulfill this condition prior to plan approval.) 72. EMERGENCY OVERLAND STORMWATER FLOW/SUMP PROPERTIES: All properties shall be designed with an emergency overland flow path to direct storm runoff to the nearest public street or open flood control facility in the event on-site pipes become plugged. The flow path shall be lower than the finish floor elevation of all habitable structures. The flow path cannot rely on neighboring properties unless a storm drain easement across the neighbor is obtained. Sump properties must be designed to discharge the 50-year recurrence interval storm event through the pipe network before habitable structures become inundated. (Fulfill this condition prior to plan approval.) 73. STORM DRAIN FORCE MAIN: The SDFM intended to discharge stormwater from the detention basin to the City pipe network on Busch Road is shown extending across property owned by Amazon (APN 946-1250-19-6). The Applicant shall provide evidence of property rights acquired from Amazon for this private pipeline. Alternatively, the Applicant shall relocate the pipeline onto property where easement rights can be obtained. (Fulfill this condition prior to plan approval.) 74. STORM DRAIN PUMP EQUIPMENT: The planned bioretention area and detention basin to be located east of the current El Charro Road alignment will be served by pumping equipment. Said equipment could be damaged if the controls become inundated. Because this area is identified as Zone A on FEMA Flood Insurance Rate Maps and is thus subject to floodwaters, any pump equipment associated with the storm drain network shall be elevated at least one foot above the expected flood elevation. (Fulfill this condition prior to plan approval.) 75. STORM DRAIN BEYOND SUBDIVISION BOUNDARY: The Applicant shall grant a storm drain easement (SDE) to the City for any portion of the storm drain network that extends beyond the subdivision boundary including the pipe network, bioretention area, detention basin, pump system, and force main to the east. Maintenance of these improvements shall be by the City with funding from the Community Facilities District except as follows: Any weed abatement or ornamental landscaping maintenance within the bioretention or surrounding/appurtenant areas shall be the responsibility of a private entity such as the homeowner’s association or underlying property owner. (Fulfill this condition prior to map approval.) 76. SANITARY SEWER DESIGN STANDARDS: Connections to the City’s sanitary sewer network shall conform to Pleasanton Municipal Code Title 15 “Sewerage”. All buildings inhabited by human beings which are not more than 250 feet from the City’s sewer network shall be connected. All premises, parcels, and/or lots shall have independent connections to the City’s sewer network. The public
