The Boulder County Commissioners approved a 1041 permit for the pipeline location and construction through Boulder County in 2012. This process evaluated alternative routes considering the environment, land use and project cost. Final design of the project began in 2016 and right-of-way acquisition activities have been completed. Construction started in August 2018 and be completed in early 2020.
The interactive map provides an overview of the pipeline alignment as well as the anticipated schedule for pipe laying activities and road/ trail impacts. Pre-construction work may take place prior to pipe laying activities in some areas.
