About Us

Jeffco Open Space was founded as a land conservation organization in 1972 by PLAN Jeffco and The League of Women Voters of Jefferson County. These organizations proposed a unique concept to the Board of County Commissioners to preserve the scenic vistas and open lands within the county using the collection of one-half of one percent tax on sales in Jefferson County to fund the program. The voters agreed, thereby ensuring perpetual land conservation, stewardship of open space and parklands, and access for public enjoyment.

Funded with a one-half of one percent sales tax, Jeffco Open Space contributes to city and park district projects, has preserved more than 54,000 acres, and manages 28 open space parks and more than 252 miles of trails in Jefferson County, Colorado. View the Jeffco Open Space park system map.
