Broomfield Trail Project
On December 2, the City Council approved an agreement with T2 Construction, Inc. for the construction of Phase 2 of the Broomfield Trail Segment 6-Lowell Boulevard to Sheridan Parkway. Construction is tentatively planned to begin in early 2015. View the staff memo to City Council.

The Broomfield Trail will stretch a total of 22 miles once all sections are completed. It will extend from the Great Western Open Space in the southwest corner of Broomfield just east of Indiana Street to northeast of Weld County Road 6 and Interstate 25. The trail is intended to be a multi-modal trail for bicyclists and pedestrians. The trail design standard is a 10-foot-wide concrete trail with a three-foot crusher fines shoulder on one side. To date, 8.65 miles of the Broomfield Trail are built. Map of entire Broomfield Trail

The proposed alignment for the Broomfield Trail Project 2014 includes a trail that would extend west from Lowell Boulevard along the north side of the FRICO Community Ditch, continue between the Wildgrass subdivision and Glasser Reservoir, and tie into an existing trail south of the Sheridan Parkway underpass. In response to citizen concerns about pedestrian and bicyclist safety along Lowell Boulevard, the project was bid with an add-alternate option for a trail connection along Lowell Boulevard, from West 144th Avenue north to Community Ditch. View map.

A consulting firm completed an environmental review in March 2014 of 1) wetlands, 2) Federally Threatened and Endangered Species (TES), and 3) other wildlife and migratory birds. View the report.
