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 56,000 acres, and manages 27 open space parks and more than 251 miles of trails in Jefferson County, Colorado. View the Jeffco Open Space park system map.

Project Web Map In December of 2019, Jeffco Open Space embarked on the development a new Projects Web Map. The goal has been to create an engaging internal and external resource that highlights major open space projects within a geographic environment. The web map is designed to relay project information and connect people to additional resources. Utilizing ArcGIS Online, Jeffco Open Space can configure spatial and non-spatial project information and easily share it with anyone who has an internet connection. This resource will evolve with project updates and future opportunities overtime. Project Web Map Desktop Version Link Project Web Map Mobile Friendly Version Link
