Boulder Open Space Transmission Line Construction

Temporary trail closures in Boulder Open Space through September

Project Overview

Xcel Energy is replacing 33 structures and almost four miles of an existing 115 kilovolt (kV) transmission line located on land managed by the City of Boulder’s Open Space and Mountain Parks (OSMP) and Public Works Utilities Division. The four-mile section of line is located southwest of the city between Boulder Canyon Drive on the north and Eldorado Springs Drive on the south. The work is required to maintain  the transmission line and ensure continued electric reliability for you and others in the area. Construction is scheduled to start in late April and is expected to be completed by the end of September 2018.  During construction, we will occasionally need to temporarily close access to OSMP trails in the area. Longer-term closures are expected in Bear Canyon beginning in August 2018. For everyone’s safety, please comply with the closures. We will work closely with city staff to let you know about construction activity and trail closures.

Project Construction

We will use helicopters at times to move equipment and materials and to maintain the work schedule.  Helicopters will carry equipment and materials to and from staging sites located on Thomas Lane (near Highway 93) and near Kossler Reservoir (off Flagstaff Road).  We will use existing trails to access our right-of-way via limited ATV and vehicular use, as approved by the City of Boulder. 

Xcel Energy plans to use helicopters to reduce impacts in the work area and to move structures, materials and other equipment.
