Northwest Rail Line Final Environmental Evaluation

Since 2007, the RTD has been studying the impacts of providing rail service from Denver Union Station to Longmont in the Northwest Rail Line Environmental Evaluation (EE) as part of the voter-approved RTD FasTracks Program. The Northwest Rail Line (NWR) is a proposed 41-mile commuter rail project from Denver Union Station to Longmont, passing through North Denver, Adams County, Westminster, Broomfield, Louisville and Boulder.  

In February 2010, RTD released the NWR Draft EE for public review. The release of the document was followed by a 30-day comment period. Three project-wide public meetings took place in March 2010 to present the NWR Draft EE to the public and to solicit comments, feedback and input. More than 200 individuals attended the meetings with nearly 80 comments received during the comment period. On May 18, 2010, the RTD Board of Directors adopted the NWR Final EE; this action allows the project to move towards final design, construction and operation as funding becomes available for the FasTracks Program. As the project advances, RTD will continue to work with local, state and federal agencies, local jurisdictions, stakeholder groups and members of the general public along the NWR project to address issues or concerns relating to this project.

All comments and responses are included in their entirety in the Final EE. A summary of the most common issues is included in the latest issue of the Northwest Rail Corridor Times newsletter.
