As the Open Space program has grown in size & significance, PLAN Jeffco continues to provide citizen oversight and impetus for new program directions—citizens & government interacting to achieve a goal of conserving Open Space Lands. We also provide an important citizen education function, keeping you informed of what is going on in your Open Space Program.
