Page 7 of 12 and 15 percent would be age-restricted to seniors. The applicant’s preferred plan includes considerably fewer age-restricted units than the County's entirely senior residential proposal. At the February 18, 2025, meeting a City Council majority supported a mix of age-restricted and non-age-restricted, housing, but did not indicate a preferred percentage of each. With respect to total unit count, City Council members have previously raised concerns about various project impacts, some of which directly pertain to the total unit count and percentage of age-restricted units; these issues include traffic and school capacity. Other concerns raised relate to development in general, including geotechnical suitability, and hazardous materials. Traffic Regarding traffic, the City’s consultant prepared a study to analyze the impacts of new traffic generated by East Pleasanton development on key roads and intersections, and looking in particular at the triggers for, and effects of, construction of an extension of El Charro Road. As outlined in the Supplemental Memorandum distributed for the February 18 City Council meeting, the Kiewit project would trigger the need for El Charro Road to avoid unacceptable congestion at Santa Rita Road/Valley Avenue; future developments including Arroyo Lago, East Lakes, and a project on the Amazon property would further contribute to this need. The study concluded that, with buildout of all projects, a 4-lane El Charro Road from Stoneridge Drive to Stanley Boulevard would be needed to fully address future traffic volumes and impacts to the existing network. The traffic study looked at the smaller County-proposed 445-unit Senior project in its evaluation for the East Lakes site. It is acknowledged that increasing the number of units, and increasing the proportion of non-senior units, would also increase overall traffic generation. With the mix of uses in the preferred plan, the PM peak hour traffic would increase by around 45% (equivalent approximately 140 additional PM peak hour trips). While staff is working to update the study to reflect the applicant’s preferred project, in the City Traffic Engineer’s opinion the study’s findings are unlikely to change such that El Charro would still be a required improvement. In its preferred -lane configuration, El Charro would have adequate capacity to accommodate a larger increment of project traffic. Furthermore, as noted above, increasing the number of units would help to support the funding of this costly improvement, by helping to spread the costs across an increased unit count to create a more feasible cost-burden per unit. School Capacity Regarding schools, in an initial discussion with City staff, PUSD staff indicated that due to declining enrollment, the District expects to have sufficient capacity for additional students generated from the applicant’s preferred plan. However, residential development in East Pleasanton could create challenges for elementary school boundaries due to projected future enrollment at individual schools. Mohr Elementary would have the greatest capacity to absorb students from new East Pleasanton development. Improved vehicle and bicycle/pedestrian connections from East Pleasanton to Mohr Elementary would be necessary to provide convenient school access while minimizing traffic impacts. Staff will continue to work with PUSD to provide a thorough assessment of impacts to schools at all levels (elementary, middle and high schools), which considers the projected impact of new students generated by the project. Geotechnical Suitability and Hazardous Materials City Council members have also raised concerns about geotechnical and hazardous materials Page 330 of 348
