Coston Street Sidewalk Project

On March 27, 2024, the Commission adopted Concept #2 - Attached Sidewalk, which replaces on-street parking with extended bulb-outs at select properties.

• Redesign will be completed in FY24.
• Property purchases, as needed, to occur in FY25.
• Construction year is not yet programmed.

The Ada County Highway District (ACHD) will consider the adoption of a concept alternative for the Coston Street Sidewalk Project during the March 27, 2024 hearing. The meeting will begin at 6 p.m.; however, this project is one of several agenda items and may not be the first item discussed. ACHD staff will make a brief presentation followed by an opportunity for public comment before the Commission acts.

Alternatives under consideration:

• Concept 1- detached sidewalks
• Concept 2- attached sidewalks

Both concepts include:

• Curb, gutter, and a 5-foot sidewalk on both sides of Coston Street from Warm Springs Avenue to Franklin Street.
• Rebuilding Coston Street from Warm Springs Avenue to Franklin Street.
• Adding and/or improving pedestrian ramps.
• Constructing bulb-outs at all major intersections along Coston Street (Bannock Street, Jefferson Street, State Street, Washington Street, Franklin Street, Mobley Drive, and Hillview Drive).
• Retaining most existing sidewalk.

• Concept 2 - Attached Sidewalk
• Typical Sections

Residents along Coston Street were asked via a petition (administered and circulated by the East End Neighborhood Association) if they supported bulb-outs and sidewalks in place of on-street parking at some locations. Enough residents signed the petition prompting ACHD to design the two alternatives shown.

• Public Outreach Infographic
• Public Outreach Comment Summary

There were 117 total respondents to the survey, with most in favor of the proposed design.

• 82% (96 respondents) were supportive of the project.
• 12% (14 respondents) were unsupportive of the project.
• 6% (7 respondents) were unsure of the project design.

Frequently Asked Questions

• Why were bulbouts on Coston Street at Hillview Drive included in the project design?

There are significant utilities at the Coston and Hillview intersection. The bulbout placement here allows the pedestrian ramps to be compliant with modern standards.

• Will ACHD need to purchase my property for the project?

Most of the improvements fit in the public right-of-way and ACHD will not need to purchase much property.

However, Temporary Construction Easements (TCE) will be needed along some properties. This is so we can repair and clean any driveways impacted by construction.

• Why aren’t there more traffic calming methods in place?

Due to the current 20 mph speed limit and traffic volumes, additional traffic calming is not currently necessary for this corridor.

• How does ACHD decide what trees are removed and which ones are not?

ACHD works hard to impact trees as little as possible when designing improvements. Unfortunately, sometimes trees must be removed due to sidewalk impacts, utilities, and updated pedestrian ramps.

The trees slated for removal are identified and reviewed by a City of Boise Arborist, ACHD, and Boise Parks and Recreation. ACHD pays to have the trees removed as part of the construction cost.
