Council backs HSIP grant application for intersection improvements at 190th and Ridgeview; roundabout recommended
Summary
Council authorized staff to apply for a Highway Safety Improvement Program grant for intersection improvements at 190th Street and Ridgeview, recommending a single‑lane roundabout with truck apron; motion carried 5‑0 with county and school district coordination.
The Spring Hill City Council approved submitting an application to the Kansas Department of Transportation (KDOT) for a Highway Safety Improvement Program (HSIP) grant that staff said would fund intersection improvements at 190th Street and Ridgeview — an area with heavy school traffic and a history of crashes.
City Engineer Allison Abel summarized the HSIP selection method: traffic data and a hazard heat map developed with consultant HDR guided candidate intersections; KDOT safety staff advised the city to avoid duplicative work on Highway 169 while a larger corridor study is underway. Council and staff landed on 190th and Ridgeview as an eligible intersection with strong benefit‑cost potential.
Staff recommendation: Based on traffic patterns, school proximity and current and anticipated development, staff recommended a single‑lane roundabout at the intersection. The design would include a truck apron to accommodate large vehicles and allow emergency and truck passage. Abel said the HSIP grant could cover up to 90% of costs; the city would be responsible for the 10% local match. The county oversees most of the intersection right‑of‑way (three of four corners), and staff reported they have requested a letter of support and will seek county participation for the local share.
Motion and vote: The council authorized staff to apply for an HSIP grant for the intersection improvements at 190th and Ridgeview. Vote: motion carried 5‑0.
Why it matters: Staff said the intersection experiences high crash rates during peak school travel and that a roundabout would improve safety and traffic flow during school drop‑off and pick‑up. The grant’s high federal match rate (up to 90%) makes it a cost‑effective candidate to address a long‑standing local safety concern.
Next steps: Staff will coordinate with Johnson County Public Works and the school district, refine project cost estimates and pursue the HSIP application. If awarded, the project would advance design and construction scheduling; staff noted the grant is an annual program and the city can reapply for other candidate intersections in the future.
