Hayden council hears update on PEL study for Hayden/Hunter corridor; public meetings set for spring

The Hayden City Council on Jan. 28 heard an update from Idaho Transportation Department (ITD) staff and the Kootenai Metropolitan Planning Organization (KMPO) on a Planning and Environmental Linkages (PEL) study examining alternatives for a multi-segment transportation system connecting Interstate 90, U.S. 95 and Highway 53 across the Rathdrum Prairie.

The presentation traced a series of prior transportation studies dating to 1997 and described how those efforts, plus a 2009 access-plan and a 2021 alignment update, led ITD and KMPO to the current PEL. KMPO staff said the PEL narrowed roughly 50 initial concepts through screening to 13 alternatives and will narrow those to three or four this spring and then to a final one or two alternatives by summer. ITD said the PEL is being used to identify a locally preferred system that can support future National Environmental Policy Act (NEPA) study work and competitive grant applications.

Council members and the mayor raised concerns about near-term development pressures along two‑lane roads (notably Hunter) and the risk that housing construction could outpace transportation capacity. KMPO staff emphasized that funding outcomes depend on having a defined, supported alternative; federal and state competitive grants—including large programs that award funds for projects in the hundreds of millions—require a clear engineering and planning foundation before funding is likely to follow.

ITD described the range of alternatives under study: “D”-type concepts would function with signals and direct access (more local street character), while higher‑access variants such as alternative H would be limited‑access, divided corridors with interchanges and overpasses. During the meeting an ITD/KMPO speaker estimated a major limited‑access alignment could be in the low‑hundreds of millions of dollars and said some conceptual builds could approach the $200–$300 million range depending on scope and interchange spacing.

Council members and attendees asked about environmental and water‑resource impacts. KMPO staff said stormwater design for highways follows DEQ and EPA standards and that typical roadside swales and filtration are used to reduce runoff reaching groundwater. Presenters noted septic systems and direct injection from septic infrastructure are a separate concern and recommended continued coordination with the aquifer board, DEQ and other water authorities in project design.

ITD staff said a public comment and outreach round is expected in spring (the presenters repeatedly referenced March for open‑house events), with alternatives narrowed further by summer. Staff emphasized the study’s role: to provide the technical basis needed to pursue NEPA and competitive funding, not to commit funding or immediate construction. Attendees were told there will be another public meeting this spring where the community may review and comment on the narrowed alternatives.

The PEL presentation also reviewed recent local projects derived from past planning work: a roughly $10 million FASTLANES federal grant that funded safety and operations work on U.S. 95, and signal work intended to improve connectivity between Government Way and other corridors. Presenters urged regional coordination and said history shows projects can move rapidly when legislative or congressional priorities and funding align, but they cautioned users should not expect an immediate construction schedule—timelines depend on funding and political will.

Next steps identified at the meeting: a spring public open house to present the level‑2 narrowing, further technical screening to reduce options to three or four, continued coordination with DEQ and the aquifer board on environmental issues, and preparation of materials to support later NEPA work and grant applications.

Speakers at the presentation included Glenn Miles of KMPO and Carrie Gentry of the Idaho Transportation Department, with local elected officials and staff participating in Q&A.
