Baseline Project:  Palo Alto Medical Foundation (PAMF) Mitigations
  • Concern of the effects on the adjacent San Carlos Airport
  • Concern that improvements to interchange might not be necessary; requested clarification as to why improvements are needed
  • Signalized intersection allows for enhanced pedestrian/bike safety
  • What is lifespan of improvement?  (20 year projection)
  • Concern that this baseline only looks at traffic improvements and does not account for bike/pedestrian safety
  • Traffic light helps with the unobstructed flow across Holly Street, but there are still pedestrian/bike safety issues associated with this improvement
  • What is the change in LOS?
  • Modification to the US 101 off-ramp may lead to back up on the freeway corridor

Alternative A:  PAMF Mitigations + Close Southbound (SB) 101 Offramp to Holly Street

  • Concern of widening on Holly Street
  • Concern of added congestion on Brittan Avenue
  • Request that a study be done to evaluate how many automobiles use the route for which Alternative A would require
  • What is the impact on the Industrial Road/Holly Street intersection?
  • Emergency access concern on southbound US 101

Alternative B:  PAMF Mitigations + Close SB 101 Onramp from Holly Street

  • Concern that traffic would be pushed elsewhere (BrittanAvenue/Harbor Boulevard)
  • Concern that clover leaf would not present a safe option for bike/pedestrian travel
  • Concern of cumulative In-N-Out Burger development, specifically related to traffic and increased pedestrian activity
  • Bike/pedestrian safety should be at forefront of improvements
  • Indicated a need for a pedestrian crossing at Industrial Road/Holly Street

Alternative C:  PAMF Mitigations + East San Carlos Bike Boulevard

  • Concern of truck traffic on East San Carlos for bike safety
  • Signage and low traffic volumes would help with safety
  • Close East San Carlos to Industrial Road to decrease use as major thoroughfare

  • Concern that bicycle boulevards to not vastly improve bike safety
  • Concern that this alternative does not address the crossing of El Camino Real
  • Questioned how a bicycle boulevard would differ from existing bicycle routes
  • Only focuses on one to two roadways, limited in scope

Alternative D:  Optimized Use of Existing Holly Street Curb to Curb Width + Full Partial Cloverleaf Interchange

  • Suggested square-off of the Holly Street/Northbound US 101 On-Ramp/Southbound US 101 Off-Ramp intersection
  • Suggested shifting the traffic signal for the US 101 Northbound On-Ramp to provide better safety for bike/pedestrian crossing
  • Combine improvements to Holly Street with interchange and bike/pedestrian improvements from Alternative C
  • Signal timing should be included
  • Lane alignment should be designed for traffic and bike/pedestrian safety issues
  • Concern of queue on left turn lane on eastbound Holly Street at intersection with Industrial Road
  • Concern for bike safety and intersection with new signal - helps pedestrian but not bikes
  • Traffic signal at Holly Street/Industrial Road intersection needs to be improved

  • Concern that the one-way road could result in driver frustration
  • Concern that this would only move traffic problem to a new roadway, such as Old County Road
  • Enhances bike/pedestrian safety
  • Path between Caltrain Station and the future PAMF should be available, easy, direct and safe
  • Need to consider traffic increase on adjacent roadways; concern that the design will result in movement of flow elsewhere

Alternative H:  Taylor Way / Terminal Way One-Way Couplet + Full Partial Cloverleaf Interchange

  • Emergency access concern
  • Concern of the air quality impacts associated with this alternative
