OSMP Projects

The City of Boulder’s Open Space and Mountain Parks (OSMP) Department will highlight large projects for 2020 on this page. 

Anemone Hill Trail Construction

Beginning in March 2020, a trail contractor will begin preparatory work for constructing the three-mile trail loop at Anemone Hill. Visitors may see small equipment and laborers working on-site, as well as materials and equipment being staged. Some short-term trail closures may be necessary for public safety.  More information on this project will be posted at this web page and on signs in the project vicinity in the near future.

Trails 2020: A Public Open House

Volunteers working on a trail

OSMP held a community open house on Thursday, Feb. 27, to inform community members of upcoming trail projects and maintenance efforts that OSMP will conduct in 2020.

View posters from the open house pdf.

This in-person learning experience informed community members of trail building, repair and maintenance efforts and featured information on:

  • Planned construction that will extend the Anemone Trail into a 3-mile trail loop west of Boulder.
  • Upcoming work along the Cottontail Trail northeast of Boulder, which will help OSMP to complete major maintenance work along the important commuter path.
  • Continuing trail projects along popular paths, including the Mount Sanitas Trail, Tenderfoot Trail, 1st-2nd Flatiron Trail, and the junction area of Fern Canyon and Mesa Trails.
  • Information on how OSMP completes full-sweeps of its 155-mile trail system to prioritize trail repairs, and volunteering on trail projects will also be available.
  • The new Boulder Area Trail App, which provides information on OSMP trails along with paths managed by 11 other Boulder-area agencies. OSMP also will highlight its interactive trail map and an online tool that shows which OSMP trails that receive the most AND least visits.

Eldorado Canyon to Walker Ranch Connection

A group of three local and state governments have proposed a preliminary interagency recommendation for a multi-use trail connection between Eldorado Canyon State Park and Walker Ranch. After collaboration to complete a Trail Feasibility Study and careful consideration of the findings, Boulder County Parks & Open Space, the City of Boulder Open Space and Mountain Parks, and Colorado Parks and Wildlife are jointly recommending the North Route (using segments N1-N2-N4) as the preferred alignment for an Eldorado Canyon to Walker Ranch multi-use trail connection.
