Jefferson County Open Space

Jefferson County Open Space (JCOS) manages one of the greatest open space park systems in the country. The abundance of parks and trails is the reason many of us have chosen to live in the Colorado Front Range. The open space properties are cherished by mountain bikers for their wealth of local riding opportunities and, as a result, bicyclists make up approximately half of all the visitors to the parks.

Maps of all the open properties in the park system can be found on this PDF: http://jeffco.us/parks/documents/parks-and-trails-documents/open-space-system-map/

The open space park system started as a citizens' movement led by PLAN Jeffco. After heavy campaigning by 400 PLAN Jeffco volunteers, the Jefferson County voters approved taxing themselves 0.5% to fund the purchase of open space on November 7, 1972.  Jefferson County Open Space was born. The parks and their funding have had to be defended by the citizens of the county several times since 1972.

In addition to these staff members, the  Open Space Advisory Committee (OSAC), a citizens' advisory board, makes recommendations regarding Open Space policy and procedures to Jefferson County's Board of County Commissioners. OSAC holds monthly meetings, open to the public, and are on the first Thursday of each month, beginning at 7 p.m. in the Ponderosa Room of the Jeffco Open Space Administration Building, Suite 100, 700 Jefferson County Parkway, Golden, CO 80401.

COMBA regularly interacts with all of these groups to help ensure the preservation of the open space park system and mountain bikers' access to these properties.
