B&N completed the study of the realignment of Orchard Street for the Ada County Highway District (ACHD) in Boise, Idaho. As the project lead, B&N examined options for moving Orchard Street to the western limits of a land parcel owned by the Boise Airport while establishing it as a Mobility Arterial that would support vehicular, bicycle and pedestrian traffic.
The final design concept developed by B&N included:
- Three multi-lane roundabouts sized to accommodate over-sized, overweight vehicles
- Multi-use paths
- Access management strategies
- Realigned Gowen Road to improve roadway geometry
- Phased construction recommendations for the project
Because the realignment is adjacent to several landfills, significant coordination on recommendations for drainage and cross street connections was required between the study team, ACHD, City of Boise and Idaho Department of Environmental Quality (IDEQ).
B&N led a stakeholder and public involvement process that sought to gain consensus among local agency representatives and property owners on the best plan for the realignment. To assist in this effort, GIS and CAD visualization tools were used.
