Quigley Sub-Area Plan April 19, 2017 Don Kostelec, AICP Alta Planning + Design, Boise, ID Photo Credit: Bike Walk Wichita
Purpose • A more focused evaluation of transportation network connectivity in the area served by Quigley Road and Fox Acres What has happened since the Hailey • Transportation Master Plan was adopted nearly a decade ago? • What would be likely impacts of buildout of proposed developments? • Help City provide guidance to current proposed development on analysis and potential requirements

Collector Streets
Collector Streets • Overall Goal: Distribute transportation users between local streets and arterials • May serve as an “arterial” for pedestrians and bicyclists • Are part of a network to support their distribution function
Collector Streets ?
Why connectivity? 1. It’s safer—for everyone. 2. Creates redundancy in the network 3. Better serves pedestrians, bicyclists & drivers 4. Improves delivery & efficiency of city services 5. Gives you more options for SH 75 Post-1950s Pre- 1950s Source: Norm Garrick Presentation

Why connectivity for active transportation?
Traffic Impacts • Roadway links function well and are generally within acceptable thresholds (very common) • Intersections are where vehicular traffic flow impacts occur • Fox Acres & SH 75 in buildout of existing phase • Also influenced by other, past developments in the area
Quigley Development Traffic Impact Study - Agree with methods and science applied throughout the study - Went beyond the norm for traffic counts for this type of development - 1.6% “background” growth per year - Not a through highway, so little traditional background growth - Therefore, it captures some level of growth from other future development - Traffic volumes are low on almost every street , - Therefore even large increases in % of traffic does not impact Level of Service
Quigley Development Traffic Impact Study - Existing traffic and buildout traffic on Bullion (what is the change) - While it sounds high because it goes from 105 to 250 in a peak hour. That seems significant, but the LOS does not change even with that amount of traffic. - Might be different if Bullion was on the border of something unacceptable, then it might look different - Croy & 8 th – A now, B no-build, C in worst case scenario - Numbers are low all-around; Likely that many of the numbers - Do not see that it will increase ff f ld l k l
Fox Acres & SH 75 • Currently: 85% of traffic goes north; 15% goes south • Right turn from Fox Acres to northbound SH 75 currently over capacity in AM peak period • Assuming similar split and worst case scenario of existing Quigley proposal (diagram at left) AM Peak: TODAY
