Trail Assessments

With over 56,000 acres of managed land, 252 miles of trail, 27 parks and high visitation, taking care of existing parks and trails is top priority for Jeffco Open Space. In order to do this job effectively and efficiently, an annual trails assessment was implemented. This assessment helps to develop work plans and priorities for trail maintenance, identify opportunities for volunteer stewardship projects by groups or as a special event, and communicate to visitors where maintenance will be occurring.

Jeffco Trails Plan

The Jeffco Trails Plan is the first-ever, Countywide trails plan that envisions a healthier, engaged community connected by trails. The Plan is a result of a collaborative effort that included multiple partner organizations and extensive community engagement to identify trail opportunities and implementation strategies that increase safety, access, and connectivity of Jefferson County trails or greenspaces.

The Jeffco Trails Plan aspires to provide County residents access to a trail or greenspace within a 10-minute walk in the plains and 10-minute drive in the mountain areas. The Plan identifies specific goals and strategies to be pursued and achieved through collaboration with partner organizations and funding through the Trails Partnership Program.

Trail Proposal Process

Jeffco Open Space allows for proposals of new trails and has an application process for those that want to submit a proposal. After submittal, a trail proposal application will be assigned an initial priority ranking, which will determine when subsequent evaluation will take place or if the project will be declined at that time. Potential trails that offer the greatest value to Jefferson County residents will be given the highest priority and moved into the Planning step as outlined in the Trails Development Handbook.
