2 of 2 To accomplish these goals, the City’s traffic model was used to model traffic generation associated with different development scenarios, based on the projects’ anticipated construction timelines. The Study first establishes a baseline level of service at key intersections, then adds the projects individually, and for each successive project evaluates its impact on the circulation network. The projects were assumed to develop in the following sequence and per the following project profiles: 1. Kiewit - 310 single family homes (SFH), 102 multifamily homes (MFH), 57 ADU’s 2. Arroyo Lago - 194 SFH, 49 ADU’s 3. East Lakes - 357 age-restricted SFH, 88 assisted and independent MFH 4. Amazon - 650,000 square foot distribution center The Study evaluates traffic volumes on key roadway segments, and intersection level of service (LOS) at 16 intersections with and without El Charro; it also provides analysis of future travel patterns to determine the effect of the extension on cut-through traffic. Broadly, the study concludes that El Charro is needed as a four-lane roadway from Stoneridge Drive to El Charro Road, and the extension is needed at or near the completion of the first project (Kiewit). Additional development would further contribute to the need for the extension. The modeling further concludes that the extension would not substantially change the overall volume of cut-through traffic, but would benefit Santa Rita Road, the most heavily used cut-through route, by shifting traffic to the new El Charro. As described in the February 18, 2025, City Council Agenda Report, since the East Lakes project was submitted to Alameda County, new alternatives have been formulated that include more units and a mix of non-age-restricted and senior housing. The modeling for the Traffic Study was well underway at the time these alternatives were proposed, and so they are not reflected in the attached study. In staff’s initial review, the proposed alternatives would increase the project’s trip generation but would not change the overall conclusions of the study as outlined above. Attachments: 1.
