The near-final language for Westminster’s signs at the new entrance to open space trails on the former Rocky Flats nuclear weapons site. A map of Rocky Flats National Wildlife Refuge, including the proposed route for the Rocky Mountain Greenway. Westminster open space and a popular dog park border Rocky Flats on the east side, and Boulder County Open Space is adjacent on the north. Westminster’s council voted in 2025 to not build easy connections for its current trails to the expanded entry points into Rocky Flats. Trails meander across the landscape of Rocky Flats National Wildlife Refuge in this July 25, 2025 photo.
