  1. Outline • Board Direction • Tasks Completed • Recommendation

  2. Board Direction • Approved motion from December 2008 • 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

  3. Board Direction • Additional Requests • 3 Chicane model • 91st Street crash data • Leon County canopy road program

  4. 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)

  5. Path Widening/Relocation

  6. Path Widening/Relocation

  7. 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

  8. 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

  9. 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

  10. 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

  11. 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

  12. Stormwater Impacts – Pre-Construction

  13. Stormwater Impacts – Post-Construction

  14. 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

  15. 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

  16. Chicane Only Model

  17. 3 Chicane Model Chicane #1

  18. 3 Chicane Model Chicane #2

  19. 3 Chicane Model Chicane #3

  20. Chicanes Only Model • Chicanes only model is not a viable option • Driveway conflicts • Sight distance issues

  21. Crash History on 91st Street • 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

  22. Crash History on 91st Street

  23. Crash History on 91st Street

  24. Summary of Speed Study

  25. Relationship of Speeds & Crash Rate • Crash rates are lowest when posted speeds are at 85th percentile

  26. 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

  27. Recommendation • Approve the 60% design plans as presented which include widening the existing multi-use path to 8’ and relocating the path to the edge of the right-of-way where feasible. • Direct staff to complete plans.
