    • Conceptually approve the 60% plans with the traffic calming
    • Widen path to 8 feet and move to edge of right-of-way where possible
    • Discuss with GRU the feasibility of underground utilities
    • Insure no additional stormwater impacts
    • Refer issue to Bicycle/Pedestrian Advisory Board
board direction1
Board Direction
  • Additional Requests
    • 3 Chicane model
    • 91st Street crash data
    • Leon County canopy road program
path widening relocation
Path Widening/Relocation
  • Tasks Completed
    • Horticulturist and Arborist reviewed relocation
    • Field meeting with Commissioner Byerly
    • Meeting with affected property owners
  • Results
    • Relocated path south of NW 1st Place to back of right-of-way
    • Meandered path north of NW 1st Place and widened to the east (toward the road)
path widening relocation3
Path Widening/Relocation
  • Benefits
    • Additional space for landscaping
    • Additional stormwater storage within the swales
  • Issues
    • Requires relocation of approximately 1600’ of fence
    • Reconstruction of path
      • Some underbrush removal
      • Potential adverse impacts to root systems
underground utility discussion
Underground Utility Discussion
  • Tasks Completed
    • Meeting with GRU (February 2nd)
    • Utility coordination meeting (February 16th)
  • Discussion
    • Life-cycle cost of underground vs. overhead
    • Types and locations of utilities along 91st
    • Potential impacts
    • Costs
underground utility discussion1
Underground Utility Discussion
  • Benefits
    • Better conditions for canopy development
  • Issues:
    • Life-cycle: underground is cost-prohibitive
    • Location: Cox Communications co-located on poles; AT&T and GRU water/waste water underground
    • Impacts
      • GRU easement requirements
      • Existing underground utilities
      • Trees
    • Costs (only for main line): GRU $1,000,000; Cox $450,000
underground utility discussion2
Underground Utility Discussion
  • County pays
    • Approximately $1,450,000 for main line
    • Plus cost of connections to homes
  • County cannot force utilities to move existing facilities underground
stormwater impacts
Stormwater Impacts
  • Tasks Completed
    • Kimley-Horn and Associates completed a drainage analysis of basin
    • Analysis was performed based on 60% plans as presented
      • 8’ wide multi-use path
      • Proposed traffic calming features
bicycle pedestrian advisory board
Bicycle/Pedestrian Advisory Board
  • Tasks Completed
    • Presented to BPAB on February 24, 2009
  • Results
    • BPAB recommended leaving path in place and widen to 8’ where possible
      • Same recommendation as Citizen’s Advisory Committee
bicycle pedestrian advisory board1
Bicycle/Pedestrian Advisory Board
  • Benefits
    • Less likelihood of impacting trees as compared to relocation
  • Issues
    • Requires reconstruction of sidewalk
    • Possible decrease in storage capacity of swales

  • Reviewed crash history
    • Data from 2002-2007
  • Standard practice to review crash history prior to beginning resurfacing, restoration and rehabilitation projects
  • May indicate problems with existing conditions
relationship of speeds crash rate
Relationship of Speeds & Crash Rate
  • Crash rates are lowest when posted speeds are at 85th percentile
leon county canopy road information
Leon County Canopy Road Information
  • Nine designated scenic roads
  • Mix of arterial, collector and local roads
    • Speed limits range from 30mph to 55mph
    • Traffic volumes range from 2,000 ADT to 7,000 ADT
  • Mix of driving surfaces
recommendation
