COLE/LAKE HAZEL INTERSECTION PROJECT
Ada County, Idaho

PROJECT DESCRIPTION

The intersection of Cole/Lake Hazel, located in south Boise, is currently a three-legged intersection with a future fourth leg proposed to the east. Lake Hazel Rd. is a major arterial roadway across south Ada County and long term will extend east eventually tying into the Eisenman interchange near Micron. Cole Rd. is a residential collector (two lanes) without sidewalks or bike lanes. It extends to the south, but ends at a rural lot subdivision about two miles south of Lake Hazel.

GOALS/OBJECTIVES:

- Design an intersection that will better accommodate all users, including pedestrians, bicycles, transit users and motor vehicles for forecasted traffic volumes twenty or more years into the future.

- Design a cross section of Lake Hazel to the east that will accommodate future traffic demand in addition to pedestrian and bicycle traffic.

- Minimize the impact to adjacent property for any design alternative considered.

- Consider a public involvement campaign and how you would go about creating one for any "unconventional" intersection design treatment.

THINGS TO CONSIDER

- Traffic volumes: morning, afternoon, and evening

- Traffic patterns - Cole to the south of the intersection has relatively little traffic today, but there is significant potential for development in the near future with nearly 2000 homes planned on the east side of the intersection. Lake Hazel connected Cole to the west just recently (within the last two years), which helps to alleviate vehicles cutting through the neighborhood to the north.

- Pedestrian and bicycle accommodations on all legs of the intersection.

- ACHD considered unconventional intersection alternatives (Continuous Flow Intersection, Michigan U-turns, flyovers) that may not be well known to Ada County drivers. These may be possibilities in designing your intersection, but how do you communicate this information to the public? What strategies will you use and how will you justify doing so based on your engineering analysis?
