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) Readiness and Environmental Protection Integration (REPI) Program, NACo supports communication and information sharing between county governments and neighboring military installations. 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.

The Department of Defense (DOD) relies on secure access to realistic live-fire training, weapons system testing and essential operational environments to build a lethal, resilient combat force. However, incompatible land-use changes near installations, including commercial and residential development, continue to erode training capacity. To address these threats, Congress created the Readiness and Environmental Protection Integration (REPI) Program in 2002 under the Fiscal Year (FY) 2003 National Defense Authorization Act. The REPI Program provides the Military Services with tools to protect irreplaceable training areas and mission-critical assets. Through cost-sharing agreements between the Military Services, other Federal agencies, state and local governments, and private organizations, the REPI Program preserves military missions by avoiding land-use conflicts near military installations, addressing environmental restrictions that limit military activities and increasing military installation resilience.

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.

The Sentinel Landscapes Partnership is a coalition of federal agencies, state and local governments, and private organizations that work with willing landowners and land managers to advance sustainable land use practices around military installations and ranges. Founded in 2013 and codified in statute through the Fiscal Year 2024 National Defense Authorization Act (10 U.S.C §2693), the partnership aligns the objectives of the U.S. Department of Agriculture, Department of Defense, and Department of the Interior to strengthen military readiness, conserve natural resources, bolster agricultural and forestry economies, increase public access to outdoor recreation, and enhance landscape resilience.

FAA-NACo Airport Land Use Compatibility

Wednesday, December 10, 2025 | 3:00 p.m. - 4:300 p.m. ET

Counties play a crucial role in our nation’s aviation system, owning and operating hundreds of airports across the country. And even in places where the county may not own the airport, county planning departments and development organizations work to maximize the value of this asset to the community’s economic and overall wellbeing. Join NACo and staff from the Federal Aviation Administration (FAA) Office of Airports Planning and Programming to learn more about the FAA’s “Advisory Circular on Airport Land Use Compatibility Planning,” which will enable counties work smarter to integrate airports into broader planning efforts for land use, economic development and more. FAA staff will also be available to answer questions from county leaders about planning needs in their community and how the Advisory Circular can guide those efforts. 

Speakers: 
 

  • Jacqueline Essick, Associate Director, Jacobsen|Daniels
  • Amber McNair, Founder & Principal Investigator, AV McNair, LLC
  • Michael (Mike) Hines, Manager of Airports Planning and Environmental Division, FAA
  • Jean Wolfers-Lawrence, Manager of Environmental Planning Branch, FAA
