description

Improvements to the intersection of Sheldon Road and Bradshaw Road are planned because threshold values for increased traffic have been met, per the process outlined in the Rural Road Improvement Policy and Standards. Based on community input and City Council direction, two options are being considered for the intersection: a signal or a roundabout. All proposed designs, currently 35% complete, take into consideration design preferences expressed in the Rural Road Improvement Policy and Standards.

PURPOSE OF TONIGHT’S WORKSHOP

• Bring everyone up to speed on the project (past part icipants and new part icipants)

• Present the signalizat ion alternat ive and the roundabout alternat ive

• Discuss benefit s and challenges of both alternat ives

• With your “ st icky dot ” , show your preference for the alternat ive you prefer – Data to be shared with Cit y Council

• Allow t ime for sharing feedback with the Cit y at the posters

TONIGHT’S AGENDA

• Presentat ion (30 minutes) – Please hold all

quest ions/ comments

PROJECT NEED

1. Intersect ion Level of Service a) Exist ing Intersect ion = LOS F

(172 to 224 seconds of delay)

b) EG Policy CI-13: All intersect ions to operate at a minimum of Level of Service “ D” at all t imes

PROJECT NEED

1. Intersect ion Level of Service (cont inued)

c) Rural Roads Policy – Invest igate Traffic Signal Cont rol as well as a Roundabout

PROJECT NEED

2. Hydraulics a) Eliminates

overtopping of the bridge and roadway during the 100 Year Flood Event

• Benefit t o emergency service access and evacuat ions if necessary

ROUNDABOUT SUMMARY

• We all drive through signals every day and are quite familiar with them

• Roundabouts are less common • Let ’s take a moment to learn more

about roundabouts

ROUNDABOUT - TYPICAL FEATURES

PRINCIPLES OF GOOD ROUNDABOUT DESIGN

NCHRP Report 672 Roundabouts: An Informat ion Guide

• Slow ent ry speeds and consistent speeds • Adequate capacit y and number of lanes • Smooth channelizat ion • Accommodat ing design vehicles • Providing sight distance, visibilit y, and light ing

• Integrat ing pedest rian and bicycle features

BENEFITS OF ROUNDABOUT

• Improved Overall Safety – 36% to 60% fewer total crashes than a

signal – Reduct ion in crash severit y in general – Nearly 100% reduct ion in fatal Crashes

• Reduced Delay – No stopping if no opposing t raff ic

• Reduced Noise • Aesthet ically Pleasing

– Adaptable to Local Context

ROUNDABOUT - BICYCLE AND PEDESTRIAN FEATURES

INTERSECTION CONSTRUCTION STAGING OPTIONS

Opt ion 1 Maintain t raff ic with 4 months of staged const ruct ion • Const ruct ion will last

addit ional months

Requires temporary detour and more ROW Opt ion 2 Full 6 week closure • Const ruct ion will last

addit ional months Impacts others outside the Sheldon area In the summer Primary detour route Secondary detour route Saves $400K to $600K

POSTER EXHIBIT INSTRUCTIONS

• Visit as many poster exhibit s as you would like

• Order does not mat ter

• Use st icky dots to inform us your intersect ion preference

• Add new ideas to the easel pads – Have had some new ideas come up through

recent discussions with property owners

• Facilit ators at each stat ion to help

NEXT STEPS

• Community input from tonight will be collected and provided to the Cit y Council on 1/ 27

• 1/ 27 Cit y Council Meet ing – Will include environmental document approval and the Council decision on a signal or a roundabout

• Design will be advanced

• Next Open House in Early 2017 – Be sure to sign-in to receive email updates

• Const ruct ion in 2017/ 2018?
