Rose Hill Street Temporary Traffic Calming

Thank you for visiting the Rose Hill Street Temporary Traffic Calming Virtual Open House. Here you will find information about the project’s background, what we’ve heard so far from the community, status of the design, and project schedule. At the end, you will be able to provide feedback on the adopted design.

If you need printed materials mailed to you or need to make other arrangements to answer your questions, please call 208-387-6100 | TTY 1-800-377-3529 and we will be happy to help you.

This open house will be open through June 29th, 2023.

During previous outreach efforts on the Boise Bench, ACHD heard from residents that there was interest in calming traffic on Rose Hill Street.

Given this feedback, the number of homes facing Rose Hill Street and traffic speeds, ACHD began examining temporary traffic calming features in early 2022 to enhance safety.

Public Outreach

After seeking  feedback from the community in March 2022 , ACHD developed several alternatives based on that feedback. ACHD presented the  alternatives to the public in June 2022 .

The ACHD Commission adopted the preferred alternative in September 2022.  View the adopted plan here .

Please note that this is a separate project from the approved mini-roundabout at the Rose Hill Street/Owyhee Street intersection which is scheduled for construction in 2024.  More information on that project can be found here. 

The design will reallocate roadway space to provide:

• On-street bike lanes on both sides of the street, separated from the travel lanes by physical separators and painted buffers.
• On-street parking on one side of the street, except between Latah Street and Owyhee Street, where the road is narrower.
  • On-street parking will alternate from one side to the other to help slow traffic.
• No center turn lane.
• The design does not impact the existing pavement or sidewalks along the corridor.

Key Design Features & Advantages

• Continuous buffered bike lanes on Rose Hill Street between Roosevelt Street and Vista Avenue.
• Tie-in to intersecting bike facilities/bikeways at Roosevelt Street, Latah Street, and Shoshone Street.
• All bike lanes will be buffered from vehicle lanes with a 2-foot painted buffer and two types of vertical elements, placed within the painted buffers. A combination of tubular markers and Zebra markers will be used to provide vertical enhancement to the painted buffers.

• Alternating on-street parking provides traffic calming.
• Does not impact private property.
• Does not restrict commercial or residential access/driveways.
• Corner treatments at Vista Avenue will slow vehicle speeds when turning and improve pedestrian crossing safety.

• Traffic circles are being considered throughout the design process. The design and placement of potential traffic circles is pending and will be finalized in coming design activities. Traffic circles will help lower vehicle speeds at key locations along the Rose Hill Street corridor.

Potential Trade-Offs

• Removes center turn lane, which will add delay to through traffic.
• Increases potential for rear-end crashes with no turn lane.

How long will the temporary traffic calming be in place?

The exact duration of the temporary measures is still to be determined. ACHD will evaluate how effective the treatments are using before and after data. Based on how treatments are performing, and in consultation with the public, ACHD will determine whether to adjust any treatments or make any treatments permanent.
