Project History ▫TIA in Aug  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

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)

Signalized Intersection 1

Roundabout Intersection 2

PIM No. 1, Feb. 8, attendees signed in

PIM No. 1 comments / themes 4 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.

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