Readiness and Environmental Protection Initiative (REPI)

The Department of Defense’s Readiness and Environmental Protection Integration (REPI) Program protects the military’s ability to accomplish its training, testing, and operational missions by helping remove or avoid land-use conflicts near installations and addressing regulatory restrictions that inhibit military activities. The REPI Program consists of three integrated components: buffer projects, landscape partnerships, and stakeholder engagements.

The REPI Program supports and funds the Military Services' cost-sharing partnerships, as authorized by Congress (10 U.S.C. § 2684a), with private conservation groups and state and local governments to protect the military mission. These win-win partnerships acquire easements or other interests in land from willing sellers to preserve compatible land uses and sustain wildlife habitat near installations and ranges where the military operates, tests, and trains. Through the REPI Program, DoD also works with stakeholders to find solutions to shared cross-boundary issues linking military readiness, conservation, working lands, and communities, such as species protection issues that incorporate protecting off-installation habitat and other mission sustainability issues.

REPI partnerships maximize taxpayer dollars by leveraging private and public cost-sharing; protecting existing training, testing, and operational assets and avoiding spending on costly alternative approaches to training, new range construction, or mission relocation when restrictions impact the regular use of testing and training lands; and enhancing military readiness, conservation, and economic outcomes.

BRAC (Base Realignment and Closure) is the process DoD has previously used to reorganize its installation infrastructure to more efficiently and effectively support its forces, increase operational readiness and facilitate new ways of doing business. DoD's most recent BRAC round was held in 2005, and it's closure and realignment actions reduced DoD infrastructure by 3.4% and generated an estimated $4 billion in annual recurring savings.

Joint Basing

The joint basing program, established by a recommendation of the 2005 Base Closure and Realignment Commission, represents the department's efforts to optimize the delivery of installation support across the services. The BRAC Report created 12 joint bases from 26 service installations that were in close proximity or shared a boundary. As of 1 October 2010, all 12 joint bases achieved full operational capability.

List of Joint Bases:
  • Joint Base Lewis-McChord, WA: McChord Air Force Base (AFB) and Fort Lewis.
  • Joint Base McGuire-Dix-Lakehurst, NJ: Naval Air Engineering Station Lakehurst, Fort Dix, and McGuire AFB.)
  • Joint Base Andrews- Naval Air Facility Washington, MD: Naval Air Facility Washington and Andrews AFB.
  • Joint Base Anacostia-Bolling, DC: Bolling AFB and Naval Station Anacostia.
  • Joint Base Myer-Henderson Hall, VA: Henderson Hall (USMC) and Fort Myer.
  • Joint Base Elmendorf-Richardson, AK: Fort Richardson and Elmendorf AFB.
  • Joint Base Pearl Harbor-Hickam, HI: Hickam AFB, HI, to Naval Station Pearl Harbor, HI.
  • Joint Base San Antonio, TX: Fort Sam Houston, Randolph AFB, and Lackland AFB.)
  • Joint Base Charleston, SC: Naval Weapons Station Charleston and Charleston AFB.
  • Joint Base Langley-Eustis, VA: Fort Eustis and Langley AFB, VA.
  • Joint Expeditionary Base Little Creek-Fort Story, VA: Fort Story and Naval Expeditionary Base Little Creek.
