Open Space & Natural Areas

To many Flagstaff area residents, open space is the defining feature of Flagstaff's character and attraction, and all of these properties were acquired after citizen initiatives (more on that below)! Open space defines the region's quality of life, protects the region's ecological health, supports tourism, and preserves historic and cultural resources.

We use Open Space Stewards to accomplish much of our work. If you love our beautiful open spaces and want to get involved, visit or click on "Open Space Stewards" on the left side of this page for more information.

Flagstaff's Open Spaces program also provides, and partners with others to provide, outdoor and nature education to kids. For more information, visit or click on "Outdoor Education Project" on the left side of this page.

The Schultz Creek Trailhead is no longer managed by the Open Space Section, after three storm water retention basins needed to be constructed there to prevent flooding after the Pipeline Fire. For more information, see the City's Pipeline Fire West Flood Area webpage and the 11/2/2022 newsletter about the completion of those basins.

Bond Initiatives

In 2004, Flagstaff voters approved two bond initiatives to fund open space acquisition efforts. These funds were leveraged with Arizona State Parks Growing Smarter grant funds to purchase nearly 2,700 acres of protected open space at Picture Canyon Natural and Cultural Preserve and Observatory Mesa Natural Area. In 2016, Flagstaff voted in favor of Prop 413, which restricted the use of 300 acres of City-owned property on McMillan Mesa to public open space and passive recreation; the official rezone to Public Open Space became effective on March 1, 2022. These areas are managed to provide recreational and educational opportunities.

On July 6, 2020, the Flagstaff City Council adopted the revised Management Plan for Legally-Designated Open Space (PDF), outlining policies and projects associated with managing the natural and cultural resources on these properties, while providing educational and recreational opportunities for Flagstaff visitors. Each year, in addition to directing efforts to meet the Program's mission, Flagstaff Open Space works to achieve the goals outlined in the Legally Designated Open Space Management Plan.
