    Thanks to local purchases and widespread public support, visitors enjoy protected places to play without entry fees. Jeffco Open Space (JCOS) funds also support projects in cities and park and recreation districts, enriching life in every corner of Jefferson County.

    The JCOS program is a credit to the foresight of engaged citizens. In 1972, PLAN Jeffco External Link Icon 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 and the funding of land acquisition, preservation, maintenance and trailbuilding followed the passage of the measure. 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 External Link Icon that shows the history and majesty of Open Space lands. We work alongside our partners in 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.
