Quigley Sub-Area Plan

Don Kostelec, AICP Alta Planning + Design, Boise, ID April 19, 2017

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

Why connectivity?

Pre- 1950s Post-1950s

• 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

Why connectivity?

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

• ccur
• 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
• n 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
• n the border of something

unacceptable, then it might look different

• Croy & 8th – 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

Fox Acres & SH 75

• Currently: 85% of traffic

goes north; 15% goes south

• Right turn from Fox Acres to

northbound SH 75 currently

• ver capacity in AM peak

period

• Assuming similar split and

worst case scenario of existing Quigley proposal (diagram at left)
