Fairfax council directs staff to prepare MPO funding application for Gate Street/Highway 151 intersection

Fairfax council instructed staff to begin preparing an application to the regional MPO for funding to improve the Gate Street and Highway 151 (80th Street) intersection, with council members debating whether to seek a roundabout or traffic‑signal/turn‑lane configuration.

Staff described the MPO’s 2050 long‑range plan process and said projects listed on the plan’s fiscally constrained list are eligible to apply. “Applications are due January 11,” the staff member said, and a successful application could shift construction to roughly 2030–2032 depending on award timing and project scope. Staff also summarized likely funding scales, saying the broader program pool covers roads, transit and trails and that the STBG‑style road grant portion in the next two‑year cycle would likely be in the low‑millions per project.

The debate centered on safety, cost and speed of implementation. A council participant warned that area traffic will grow fast, saying, “If you think traffic’s crappy now at that intersection, wait a year,” to underscore concerns about near‑term congestion tied to local development. Staff pointed to MPO and DOT team study guidance, noting roundabouts typically reduce high‑impact crashes by large margins but can show more low‑speed collisions; one council member responded that roundabouts can increase minor collisions and that signals would be cheaper and quicker to deploy.

Staff outlined responsibilities and timing: engineering, right‑of‑way acquisition and detailed design would be the city’s responsibility if the project is funded, and some grant programs assume an 80% construction match. Staff said updated traffic counts would be required to advance design, though counts are not strictly needed to begin the application. To get more technical guidance, staff offered to invite a DOT or MPO representative to the Dec. 9 council meeting.

Council did not take a final, binding vote to submit the application at this meeting; instead members directed staff to start preparing the MPO application and return to council with estimates and a resolution for final sign‑off. Staff said a formal decision would be needed by the Dec. 9 meeting so the city can complete cost estimates, then the MPO application must be finalized in time for the January deadline.

The council’s next steps: staff will draft the application and reach out to the DOT/MPO for technical input ahead of the Dec. 9 meeting; staff will collect or commission updated traffic counts as part of preliminary design work if the city chooses to proceed to construction planning.
