After the Flood: Continuing Trail Repairs
98% of OSMP’s trail system now open, but some trails remain closed
For more than four months, trail crews with the City of Boulder’s Open Space and Mountain Parks (OSMP) Department have had a single focus: to re-open all trails damaged during the September Flood.
With the help of volunteers, they’ve re-built bridges. They’ve resurfaced miles of trails. They’ve re-routed trails around mudslides. And they’ve cleared massive amounts of boulders, snapped branches and other flood-related debris from trails.
As a result of volunteers and trail crews’ hard work, about 98 percent of OSMP’s trail system is now open. However, some trails sustained significant and severe damage and still require major repair efforts to reopen them to the public. Because of the expected limited availability of materials and contractors, who are working to complete numerous post-flood projects, completion of those projects may take some time.
Maps showing open and closed trails are available in the brown box under Re-opened Trails Maps. Nighttime and off-trail restrictions are shown on the trail maps.
Remaining long-term OSMP trail projects include (these trails are currently closed):
Gregory Canyon Road: Much of the surface of the asphalt road was destroyed. It is a long-term road rebuilding project where OSMP is developing a reconstruction plan.
Royal Arch Trail: The famous area trail sustained severe damage during the flood. The department is working with the climbing community to develop options for rehabilitating and repairing the trail.
Upper Saddle Rock Trail: There is a 10- to- 15-foot vertical wall of debris blocking the trail. Because of the location high up in the Boulder’s mountain backdrop, OSMP is unable to bring in heavy equipment to remove the flood debris. OSMP is considering rerouting the damaged section of the trail – an alternative already identified in the West Trail Study Area Plan.
Chapman Drive: It is a critical emergency access for first responders. While OSMP opened the trail from the intersection of the Tenderfoot Trail to the Flagstaff summit, Chapman Drive is currently unusable as a road. OSMP is working to develop a plan for reconstructing the road.
