Learn About Open Space Land Acquisition Program

The Open Space and Mountain Parks (OSMP) system includes more than 46,000 acres of preserved land in and around Boulder, Colorado. The very first piece of land, 80 acres at the base of Flagstaff Mountain, was purchased by the city in 1898 to be used as one in a series of Chautauqua cultural centers around the country. Since then, the Open Space program (established in 1967) has acquired over 450 separate properties.

In addition to land acquisitions, the Open Space program acquires water rights to help support agricultural operations and preserve historical water rights. Approximately 6,000 acres of open space land are irrigated with these water rights. Whenever possible, mineral rights are also acquired during the land acquisition process.

How Are Decisions Made Regarding Acquisitions?

The Open Space and Mountain Parks division acquires properties based on the OSMP Master Plan, adopted by the Boulder City Council in 2019. Recommendations for acquisitions are made by the Open Space Board of Trustees and approved by Boulder City Council pursuant to the City of Boulder Charter, Article XII, Open Space.

Methods to acquire properties:

  • Property purchases: Fee interest acquisitions are typically based on fair market value.
  • Bargain and sale agreements and land donations: Involve a donation of land as one of the components.
  • Conservation Easements: The fee interest is retained by the property owner and the owner has agreed to permanently limit their use of the land to protect its conservation values.
  • Joint acquisitions: Partner with other agencies, most notably Boulder County, on joint acquisitions.
  • Dedications: Acquisition of property interests as part of a development or annexation process.

The Open Space and Mountain Parks program is about 90 percent funded by sales and use tax dollars. 0.77 cents of every dollar spent on retail products in the City of Boulder helps support the continued acquisition and maintenance of OSMP lands; protecting the land from development and preserving it for future generations.
