Packet: City Council Work Session (10/21/2025)

• Kimberlite Street: Currently operates acceptably under existing volumes with minor delay. Future Conditions (2025–2045) Croell Avenue • Alternatives that include a tra ic signal improve operations to acceptable LOS during both peak periods. • The southbound left-turn queue may occasionally exceed existing storage length but remains manageable under most conditions. Kimberlite Street • Tra ic Signal Alternatives (Options 1–4): o Maintain acceptable LOS through 2045, though westbound queues increase during the PM peak. • Roundabout Alternative (Option 5): o Operates e&iciently in the near term (2025). o By 2045, the westbound approach operates at LOS F during the PM peak, though queues remain shorter than the signalized alternative. Safety and Design Considerations • Croell Avenue: o Topography and embankment slopes limit roundabout feasibility. o O&set right-turn lane and/or tra&ic signal control can improve visibility and reduce high-angle crash potential. • Kimberlite Street: o Both tra&ic signal and roundabout configurations are feasible. o A roundabout o&ers lower crash severity potential and smoother operations during o&-peak hours.
