Project Overview

Open Space & Mountain Parks Master Plan

For nearly 120 years, generations of Boulder residents have created an innovative public land legacy in building the city’s over 45,000-acre open space system. In September 2019, City Council unanimously accepted and adopted Open Space and Mountain Park’s first Master Plan. The Master Plan sets the course for achieving a vision for integrated and responsible land management over the next decade and beyond.

The OSMP Master Plan will shape the City of Boulder’s approach to future stewardship questions, such as: How to continue conservation of natural, cultural and scenic areas while also providing enjoyable visitor experiences, how to address population growth with increased visitation, and how the city will make its natural areas more resilient amid the climate crisis.

Thanks to all of you who shared ideas and feedback during our five windows of engagement. We have summarized the complete engagement process in Appendix A of the Master Plan.
