Grant Road Improvement Plan
Task Force Meeting

  • June 26, 2008


2
Representative Locations Design Concept (wrap-up)


  • Excess right-of-way & redevelopment
3
Excess Right-of-Way and
Redevelopment Themes


  • Land Use
  • Open Space
  • Development
  • Building Height
  • Buffering
  • New Commercial Frontage
4
Land Use
  • Broad Interest- support for open space as well as different types of development
5
Open Space
  • Liked pairing with development
    • Homes fronting onto open space
  • Concern about maintenance and safety
  • Support for multi-use path by a vocal minority


6
Development
  • Supported as much as open space
  • Support for residential and office
  • ‘Housing choice’ least popular as priority
  • Concern with:
    • Feasibility of development
    • Affordability of new development for existing businesses
    • Student housing
  • Participant ideas: courtyard offices/retail
7
Building Height
  • Overall:
    • Majority of participants seem to be comfortable with 2-3 story buildings
  • Some Locations – Fontana/Mansfield Park, First Avenue and Campbell Avenue
    • Approximately half supported 3-4 story building heights at these locations
8
Buffering
  • Overall
    • Recognition that buildings can provide effective buffer
  • Central Segment - “Preserving Neighborhoods”
    • No. 1 priority for use of excess right-of-way in
      • Buildings or open space
      • Both within the right-of-way and in excess acquired land

9
New Commercial Frontage
  • Over half of participants supported new pedestrian environment shown in “Preserving Businesses” concepts

Task Force Endorsement Process
  • Input
    • Public perspectives (neighborhoods
    •     & businesses)
    • Constituent perspectives
    • Personal perspectives
    • City guidance
    • Character segment workshops
    • Best practices, research, & analysis
    • Staff recommendation
    • City perspectives on recommendation


12
Task Force Endorsement Process
  • Evaluation Criteria
    • Guiding principles
    • Technical assessments by staff


  • Endorsement Options
    • Endorse staff recommendation
    •     and move on to the next step
    • Endorse a conditional or revised
    •     recommendation
    • Ask for more information

Public Perspectives-Major Intersection Improvements
  • Initial response divided between enhanced traditional and indirect left-turn
  • Understanding of reduced impact at representative locations led to more support for indirect left


35
Indirect Left Intersection


36
Super Street in Wilmington NC
37
Indirect Left-turn Advantages
  • Eliminating left-turns from the intersection…
  • Improves traffic operations
    • simpler signal phasing (3-phase)
    • increased green time for through vehicles (approx. 8 sec)
  • Requires less right-of-way
  • Reduces pedestrian crossing distance (from 130 ft to 110 ft)
  • Reduces conflicts and improves safety (from 32 conflict points to 24 conflict points)


38
Enhanced Traditional Intersection

Peak-Hour Modeling Results
  • Indirect-left is not a “fix-all”
    • Projected 2030 volumes are 60,000-70,000 vehicles/day
  • Individual Intersections
    • Major intersections will be congested for 60,000-70,000 vehicles/day conditions (with traditional & indirect left)
    • 50,000-55,000 vehicles/day, indirect will operate at better levels of service that traditional intersections
  • Total Grant Road Delay
    • Indirect left has less delay and improved travel time due to more E/W green time
    • Indirect left delay benefits favor Grant Road through motorists

Objectives for
Alignment Concept Graphics
  • Propose an alignment concept, and in some places, alternative alignments
  • Provide tools for Task Force to move towards a recommended Grant Road alignment
  • Explain project team’s design process


52
Orientation: Alignment
  • Propose an alignment concept, and in some places, alternative alignments
53
Orientation: Analysis

  • Provide tools for Task Force to make endorsements on a recommended Grant Road alignment
