Thanks to local purchases and widespread public support, visitors enjoy protected places to play through trail-based activities. Jeffco Open Space (JCOS) funds also support projects in cities and park and recreation districts, enriching life in every corner of Jefferson County.

Jeffco Open Space is a credit to the foresight of engaged citizens. In 1972, PLAN Jeffco worked with the Board of County Commissioners and other local governments to adopt an enabling resolution and place a ballot initiative before Jefferson County voters. The creation of JCOS provided funding of land acquisition, preservation, maintenance and trailbuilding. In 1980, voters widened the program by approving an amendment to allow JCOS funds to be used for construction, maintenance and management of park and recreation facilities.
As JCOS turned 40, we celebrated with an anniversary video that shows the history and majesty of Open Space lands and our collaboration with Great Outdoors Colorado (GOCO) and Denver Mountain Parks. We work alongside other divisions within Jeffco Parks—the Boettcher Mansion, CSU Extension and the Jeffco Fairgrounds—to uphold our commitments to practice responsible management, provide quality experiences and exchange information and foster collaboration to produce the best possible results.
