After the Flood: Continuing Trail Repairs

99% 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 99 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.
