Challenge Cost Share

Purpose and Scope:

The purpose of the Challenge Cost Share Program (CCSP) is to increase participation by qualified partners in the preservation and improvement of National Park Service natural, cultural, and recreational resources; in all authorized Service programs and activities; and on national trails. NPS and partners should work together on CCSP projects with mutually beneficial, shared outcomes.

The CCSP is a matching fund program. An equal amount of eligible and matching share (minimum 50%) of cash, goods, or services from non-federal sources is required. Currently, the maximum CCSP award is $30,000. Projects selected should generally be able to be completed within one year.

One-third of CCSP funding is set aside for National Trails System projects, supporting work under the National Trails System Act (16 U.S.C. 1241-51). National Trail System projects include those associated with National Scenic and Historic trails, National Scenic and Historic Trails in parks, National Recreation Trails, and rail-trails.

Program Status:

The CCSP is not currently accepting applications at this time.
