WOODARD & CURRAN (#2026256) - Laserfiche WebLink

City of Pleasanton 2 Woodard & Curran, Inc. Arroyo Lago Sewer Impact Study September 3, 2025 • Option 2 would convey Arroyo Lago and East Lakes flows through a new alignment along Mohr Avenue and Iron Horse Trail; Amazon flows would follow Busch Road to Ironwood Drive to the above network. Woodard & Curran will summarize the model results in a brief Technical Memorandum (TM) for review by the City. The TM will document the model updates and assumptions made for the evaluation and include model hydraulic profile plots of the flow in the relevant downstream sewers. The TM will also identify where public sewer improvements (e.g., pipe upsizing) may be needed to serve each development scenario, and the sizing of any new or upsized sewers. As the proposed developments contribute to Capacity Project 4, identified in the City’s Capacity Evaluation Report, the evaluation will also determine how the proposed Capacity Project 4 would need to change to accommodate the additional flows, based on the two conveyance alternatives described above. The pro-rata share for each of the proposed developments (Arroyo Lago, East Lakes, and Amazon) to the Capacity Project 4 project cost will be determined for each of the scenarios. Comments received from the City will be incorporated into a final TM.
