The REPI Program preserves military missions by limiting or alleviating encroachment threats and other constraints on military training, testing, and operations.  In addition to limiting incompatible development or preserving habitat that may alleviate environmental restrictions on installation or range activities, 10 U.S.C. § 2684a(a)(2)(B)(3) also provides for maintaining or improving military installation resilience, as defined in 10 U.S.C. § 101(f)(8).   To prevent mission impacts and weather-related threats to DOD training lands, infrastructure, and public safety, the REPI Program can fund off-base nature-based solutions, also known as REPI Military Installation Resilience Projects.

There are several legal authorities used by installations and partners to execute REPI Military Installation Resilience Projects.

10 U.S.C. § 2684a(a)(2)(B)(3):  Authorizes DOD to enter into agreements with state or local governments and private organizations to create, maintain, or improve off-base natural infrastructure. 

10 U.S.C. § 2679 (Intergovernmental Support Agreement):  Authorizes DOD to enter into an agreement with a state or local government to provide, receive, or share services that mitigate or remove weather-related vulnerabilities impacting military readiness.  

16 U.S.C. § 670 c-1 (The Sikes Act):  Authorizes DOD to enter into cooperative agreements or interagency agreements to protect natural infrastructure, high value habitat, and natural resources near installations.
