Connecting Counties & Military Installations
The DoD REPI Program

The DoD REPI Program is a key tool for combating encroachment on incompatible development near military installations that can limit or restrict critical military training, testing, and operations. The REPI Program preserves and enhances these military missions by helping remove or avoid land-use conflicts near installations, ranges and their associated facilities, range infrastructure and airspace, as well as addressing regulatory restrictions that inhibit military activities.
A key component of the REPI Program is the use of encroachment management partnerships, referred to as REPI projects, among the Military Services, local and state governments, and private conservation groups. These win-win partnerships share the cost of acquisition of easements or other interests in land from willing sellers to preserve land uses that are compatible with military missions and natural habitats near installations and ranges that help sustain critical military capabilities.
Counties have been active partners in REPI projects across the nation. REPI projects contribute to the longevity of working farms, forests, and ranchlands; increase recreational and open space opportunities for nearby residents and military families; and protect against military relocations that would adversely affect the local economy.
About This Tool
502 counties host U.S. military installations, representing more than 15 percent of America’s counties nationwide. In partnership with the U.S. Department of Defense (DOD), NACo is creating a Military Communities Resource Hub to share timely and relevant DOD updates and opportunities for county leaders to connect with each other and DOD representatives. This hub will primarily serve county officials who have an interest or role in coordinating with their local military installation personnel on administrative, environmental, public safety, economic development or other matters.

Featured Partner Resources
In partnership with the U.S. Department of Defense (DOD), the Readiness and Environmental Protection Integration Program (REPI) allows NACo to support communication and information sharing between these county governments and neighboring military installations. This program helps to combat encroachment on incompatible development near military installations that can limit or restrict critical military training, testing and operations.
The Department of Defense’s official project funding guide outlines how REPI funding opportunities can be leveraged for various initiatives. REPI projects contribute to the longevity of working farms, forests and ranchlands; increase recreational and open space opportunities for nearby residents and military families; and protect against military relocations that would adversely affect the local economy.
Produced by the Department of Defense REPI Program, these state-level fact sheets highlight how REPI investments are supporting military readiness, local economies and environmental resilience. Each report details the locations, funding levels, partners and outcomes of REPI projects within individual states, offering counties a snapshot of defense-community collaboration in their region.
These REPI primers provide counties and other stakeholders with practical guidance on building successful partnerships, integrating military compatibility into land use planning and addressing environmental noise concerns. Each resource is designed to support collaborative, readiness-focused planning.
- Program Partnerships Primer

In partnership with the U.S. Departments of Defense, Agriculture and the Interior, the Sentinel Landscapes Partnership connects landowners, government agencies and nonprofit organizations to promote conservation and working lands in areas near military installations. These landscapes support military readiness, preserve natural resources and bolster local economies by aligning federal and state programs with shared priorities.
