Mat t Braughton – Traff ic
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
• Poster Exhibit s (Remainder of the evening)

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
Pedest rian refuge
Pedest rian and bike bypass shared use path
Crosswalk and two-stage crossing
ROUNDABOUT - “ RURAL” AESTHETICS
ROUNDABOUT “ RURAL” AESTHETICS Cent ral Island Public Art
Tan Colored Surface to Blend with Rural Surroundings
Use of Decomposed Granite with Cobble and Accent Boulders along with zones of non-irr igated nat ive grass and wild f lowers
ROUNDABOUT - “ RURAL” AESTHETICS
ALTERNATIVE COMPARISON
Sheldon and Bradshaw Intersect ion Feature Signal Roundabout
Ant icipated vehicular delay in 2018 after const ruct ion
Fewer number and lower severit y of crashes
Increased t raff ic calming effect
Abilit y to bet ter incorporate rural aesthet ics
Reduct ion in vehicle emissions
Lower long term maintenance and operat ion costs
Eliminates overtopping of the 100 year storm event
St ream relocat ion impacts
Least amount of r ight -of-way needed

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?
