~ ~ Preliminary Traffic Study: Scope: Forecast the potential impacts of Options A and B on 13 selected intersections (Figure 1) Baseline: Existing Condition: All intersections operate at acceptable service level, LOS D (w/ approved projects) Marina/San Leandro Boulevard intersection close to LOS E (53.8 seconds/vehicle average delay) Cumulative Condition: All intersections continue to operate at acceptable service (to Year 2025) level, except Marina/San Leandro Blvd. becomes LOS E (60.4 seconds/vehicle average delay) Plus Option A: Existing Condition: Marina/San Leandro Blvd. intersection operates at LOS E (w/ approved projects) (70.4 seconds/vehicle average delay) Cumulative Condition: Marina/San Leandro Blvd. intersection operates at LOS E (to Year 2025) (76.3 seconds/vehicle average delay) Plus Option B: Existing Condition: Marina/San Leandro Blvd. intersection operates at LOS E (w/ approved projects) (57.5 seconds/vehicle average delay) Cumulative Condition: Marina/San Leandro Blvd. intersection operates at LOS E (to Year 2025) (62.2 seconds/vehicle average delay) Possible Mitigation for Marina/San Leandro Boulevard Intersection: ~ Ability to widen Marina Boulevard constrained by large columns supporting aerial BART structure and UPRR rail tracks along San Leandro Boulevard. ~ Option B: Restriping eastbound right-turn lane on Marina Boulevard to a shared right/thru lane will achieve LOS D in the near term. ~ Option A: In addition to above, restricting left turns out of the project site during peak p.m. hours (3:00 to 7:00 p.m.) on weekdays will mitigate to LOS D in the near term. Staff questions the feasibility of enforcing this option and it may be unacceptable to the retailer. • Extension of Aladdin or Montegue requires costly underpass or overpass and property acquisition dedication; preliminary cost/benefit analysis shows project is not economically feasible if cost exceeds $5,100,000.
