The City and transportation engineering firm, HDR Engineering, are working on plans to improve pedestrian and vehicular mobility on Warm Springs Road between Main Street and Saddle Road. Part of the plan includes the improvement of the 10th and Lewis Street intersections on Warm Springs Road. We are investigating potential solutions such as realignment of the intersection, a roundabout, and signalization.

Project goals:

• Address traffic calming needs and slow vehicle speeds
• Improve access for all modes of travel – walking, biking and transit
• Enhance public realm to serve as a gateway or transition zone
• Provide an intersection that will serve traffic adequately in the future

Project progress:

• April 11th – HDR Engineering briefed council regarding future transportation enhancements
• May 5th – an open house was conducted at the old lumber yard property to receive feedback from the public, businesses, and property owners
• May 13th-June 1st – city-launched on-line survey with 219 participants (view the results)
• Staff and HDR completed a screening matrix exercise (view the packet here) to compare the pros/cons of the potential five new intersection configurations
• July 18th – council agreed to further explore the following two concepts:

Refined Concept Alternative 2 – Lewis Street Roundabout

• This alternative replaces the existing stop controlled Warm Springs Road and Lewis Street intersection with a single lane roundabout.
• This concept provides good vehicle operations while requiring drivers to slow down approaching and moving through the intersection.
• Pedestrian facilities would be provided on all legs, connecting to existing facilities, and bikes would be able to travel through the roundabout due to low vehicle speeds or could travel around on pathways around the circle, crossing the legs in the pedestrian crosswalks.
• The bus stop on the west leg would be updated with this alternative.
• This concept would require widening the intersection with estimated private and public parking and access impacts.
• The adjacent Warm Springs Road and 10th Street intersection is not improved with this alternative.

Refined Concept Alternative 4 – 10^th Street & Lewis Street Realignment & Roundabout

• This alternative realigns 10th Street between Warms Springs Road and SH-75 to the north and west to match into the Lewis Street and Warm Springs Road intersection, cutting through the adjacent property. The Lewis Street leg is realigned to the east and a single lane roundabout is developed to serve the new four-leg intersection. The existing 10th Street between Warms Springs Road and SH-75 is proposed to be disconnected from Warm Springs Road but could remain as an access to existing businesses along with Leadville Avenue. The abandoned roadway could also be negotiated to be incorporated with adjacent landowners for development opportunities.
• As with the other roundabout alternatives, this concept provides good vehicle operations while requiring drivers to slow down approaching and moving through the intersection.
• Pedestrian facilities would be provided on all legs, connecting to existing facilities, and bikes would be able to travel through the roundabout due to low vehicle speeds or could travel around on pathways around the circle, crossing the legs in the pedestrian crosswalks.
• The bus stop on the west leg of Warm Springs Road would be updated with this alternative.
• This concept would require widening the intersection with estimated private and public parking, access, and building impacts along with splitting the parcel in the northeast corner.
• The adjacent Warm Springs Road and 10th Street intersection is updated with this alternative by removing the east leg as described.
