Purpose and Need

  • Purpose of the Highway 1 Corridor

Environmental Analysis

  • Reduce congestion
  • Encourage carpooling and use of alternative

transportation modes as means to increase capacity

  • Improve safety
slide-5
SLIDE 5

November 2017 5

Purpose and Need

  • Existing and Anticipated Needs to

Address

  • Recurrent congestion
  • Existing and future delays for commuters, commerce,

and emergency vehicles

  • Disincentives to use transit; congestion prevents

cost-effective transit service

  • No incentives to carpool and lack of supporting

facilities

  • Accident rates exceed statewide averages
  • “Cut-Through” traffic on local streets

Project Phasing

  • Tier I: Program-level review

(corridor)

  • Tier II: Project-level review

(segment)

  • Future Tier II projects subject to

project level environmental analysis

  • No Build Alternative
  • Does not address corridor purpose and need but offers

comparison with impacts of other alternatives

  • Transportation System Management (TSM)

Alternative

  • Lower cost improvements to partly address corridor

purpose and need without adding capacity

  • High Occupancy Vehicle Lane (HOV)

Alternative

  • Designed to fully address corridor purpose and need

Tier I Corridor - Alternatives Under Consideration

  • Interchange review process
  • Engineering design-
  • Optimize local circulation
  • Caltrans standard design and right of way impacts
  • Caltrans conceptual agreement on corridor footprint
