Planning Commission Meeting Agenda Packet 06242026

P25-0116. P25-0116, P25-0018, PUD-154 and Tract 8123 (Arroyo Lago) Planning Commission 16 of 22 includes the Kiewit and Arroyo Lago projects and assumes El Charro Road is not extended, and a scenario that assumes El Charro Road is extended between Stoneridge Drive and Busch Road. The TIA indicates that “Under Existing and Existing Plus Project conditions, all study intersections are expected to operate acceptably at level of service (LOS) D or better, except for the Santa Rita Road at Valley Avenue intersection, which operates at LOS E during the evening peak hour. Minor signal timing adjustments, such as allocating additional green time to the eastbound left-turn movement, would improve operations at this intersection to LOS D. The 95th percentile queueing analysis indicates that while a few turn movements are projected to exceed available storage, optimizing signal timing would reduce queues to available storage lengths.” The TIA also states that “Under General Plan buildout conditions, the intersection of Santa Rita Road at Valley Avenue is forecast to operate below the city’s LOS D standard across all scenarios during the morning and evening peak hours; also, 95th percentile queues are expected to exceed available storage for key movements at the intersection. With implementation of the city’s planned intersection upgrades -- specifically the addition of southbound and westbound left-turn lanes and optimization of signal timing splits—overall operations would improve to LOS D or better. Queueing conditions would also improve, with 95th-percentile queues expected to remain within available storage lengths following these improvements. Consistent with the El Charro Road Extension Assessment, these results also confirm that extending El Charro Road would further enhance corridor performance and reduce congestion on Santa Rita Road.” The TIA confirms that the proposed Project can be accommodated within the City’s circulation system with the implementation of the targeted intersections. The City Traffic Engineer reviewed the TIA and concurred with its analysis. In addition to the improvements identified in the TIA, the Project would be required to develop all internal streets to the City’s standards and to make frontage improvements along Busch Road, including sidewalk, curb/gutter, travel lane striping, etc. Specifically, the Project is required to construct a roundabout at the Busch Road/Street B intersection. The Project is also required to construct the extension of a Class I trail with a minimum width of 10 feet along the east side of Street A from Street D to Busch Road. The trail design must meet the standards set forth in the Bicycle and Pedestrian Master Plan and the Trails Master Plan. The required improvements have been reflected in the Project’s conditions of approval. Further, as analyzed in the CEQA Addendum, the Project would result in Vehicle Miles Traveled (VMT) impacts that exceed applicable adopted regulatory thresholds. While feasible mitigation measures would be implemented to reduce VMT, including design features that support alternative modes of transportation, these impacts would remain significant and unavoidable. Additional discussion on this item is in the Environmental Assessment section of this report. Notwithstanding the VMT findings, the proposed circulation improvements would enhance local traffic operations and safety on Busch Road and the local road network.
