Adams County commissioners to press for $55 million to advance passenger "end line" planning and NEPA work

Adams County transportation staff told the Adams County Board of Commissioners on May 20 that they plan to ask state and federal partners for up to $55 million to fund planning and environmental work needed to advance the region's passenger rail "end line." The request would cover advanced design, coalition-building and NEPA studies; staff said it is not intended to substitute for RTD's responsibility to build final stations.

Janet (staff member leading the transportation team) told the board that the county's preliminary research shows the NEPA process alone for the final 2.5 miles could cost "between probably $8 to $15,000,000 just for the EIS process," and that reaching higher design milestones could push total planning costs toward the higher figures staff recommended for the ask.

Why it matters: Commissioners said the county has waited decades for the end line to be completed and that county staff will need seed funding to assemble technical plans and coalition support that can be used to defend a larger construction request later. Commissioners emphasized that a large planning ask is a precondition to move the project to shovel-ready status and to attract construction funding.

What the board decided: After a detailed discussion of cost categories and milestones, several commissioners signaled support for submitting a $55,000,000 request representing the county's best estimate of what will be needed to finish design, NEPA and preparatory work. Commissioner S8 said, "So I'm all in on $55,000,000," and commissioners asked staff to document how that total would be broken into phases and milestones so the request could be defended publicly.

Staff and next steps: Staff said they will present talking points and the county's formal position at the Colorado Department of Transportation's 10-year plan hearing and the Transportation Commission meeting scheduled May 21, and at the RTD executive board session, and will solicit regional letters of support. Janet framed the county's approach as "putting our flag in the ground" to secure the planning funds rather than negotiating away the scope in advance.

What the money would cover: In staff's description, the $55 million would cover an environmental review where required (EIS vs. EA), updates to older 30% designs, technical planning and consultant oversight, coalition building among municipalities and jurisdictions, and initial engineering to bring drawings to a near-constructible stage. As Janet warned, "each time you reach that next phase, you're uncovering more information that can get you to a more detailed projection of what that project cost is going to be."

What is not decided: The board did not adopt a formal, binding resolution at the study session. Commissioners asked staff to refine the cost breakdown, prepare the Transportation Commission presentation materials, and return with supporting documentation and potential coalition letters. The request to the Transportation Commission is scheduled to be made by staff in the next session; no construction funding was approved at this meeting.

Context: County staff said the $55 million request is intended to unlock federal and state construction dollars later; they also stressed that final station construction remains RTD's responsibility and that the county's request is to help complete the planning and technical groundwork that RTD and local partners will need to proceed.

The county expects a rapid follow-up over coming weeks: staff will (1) provide a phase-by-phase breakdown of the $55 million figure, (2) circulate supporting materials to the county delegation and regional partners, and (3) present the county's talking points at the Transportation Commission and RTD executive board meetings.
