STH 145 Roundabout Presentation

Bloom Companies, LLC presents a comprehensive proposal for a roundabout design aimed at improving safety and traffic flow at the intersection previously identified for enhancements. Our multi-disciplinary team specializes in architecture, engineering, and construction, focusing on sustainable solutions. The project history includes stakeholder engagement, public input sessions, and detailed design iterations. We emphasize the design's feasibility, especially concerning historic properties, and present cost comparisons to alternative signalized options. Our commitment to stakeholder communication ensures transparency and collaboration throughout the project development process.

  4. Project History • TIA in Aug. 2009 • intersection needs improvements • March 31, 2011 – Selected for Master Contract project • Mid June 2011 work order is approved • Late June 2011 survey completed • OPM held Sept. 27, 2011 • 30% plans completed Dec. 12, 2011 • 1 Signalized design • 1 Roundabout design • PIM No. 1 on Feb. 8, 2012 • ICE approval on June 6, 2012 • Roundabout recommended

  5. Design process • Original thought presented at OPM: • Center the Roundabout, show historic school house impact (basis for design) • Was told any design involving historic properties must be feasible and leave historic property intact. • Slide center of intersection NE within both options • Multiple iterations and discussions with Ourston on Roundabout design • October thru early December 2011 • 1 Signalized design and 1 Roundabout design submitted to Department and Village for comments (seen in agenda package)

  6. 1 Signalized Intersection

  7. 2 Roundabout Intersection

  8. 3 PIM No. 1, Feb. 8, 2012 42 attendees signed in

  9. 4 PIM No. 1 comments / themes • 12 comment forms turned in; comments include: • 1) Concern for speed on 145, mentioned roundabout could help this • 2) One misunderstood roundabout to be 2 lane with need to switch lanes • 3) 3 liked the roundabout idea, 1 liked safety of Roundabout • 4) 7 said no roundabout, multiple mentioning lower cost of signal option • (incorrect assumption) • Signal = $1.9 million • Roundabout = $1.4 million • 5) Concerns about utility lines, trees and ability to make left out of driveway • 6) Waste Mgmt – desires signal or 50% larger Roundabout • 7) 1 thought – signal easier on semi’s and garbage trucks • 8) 2 concerned about space required for roundabout • 9) 1 said go with signal due to cost (see above #’s) • Shared with stakeholders on Feb. 9, 2012 via synopsis / overview doc.

  10. 4 ICE Review • 9 different areas within chart, operational analysis shown below.

  11. 4 ICE Review, continued • Signal LOS = C Roundabout LOS = B • Signal Delay = 34 seconds Roundabout Delay = 14 seconds

  12. 5

  13. 6 Project initiation

  14. 7 Some items initiating project

  15. 8 TIA recommendations

  16. 9 Roundabouts VS Signals

  17. 1 Present design (Roundabout) • Safety • Speed reduction through use of Chicane

  18. 1 Present design (Roundabout) • Right-of-way impacts • Similar for both options

  19. 1 Present design (Roundabout) • Access – lost with signal but not with Rdbt.

  20. 1 Village comments desired • Can help better design • Now or later, form provided
