About the IIS Program


IIS Background

Interagency and International Services (IIS) is the U.S. Army Corps of Engineers (USACE) program providing technical assistance to non-Department of Defense (DOD) federal agencies, state and local governments, tribal nations, private U.S. firms, international organizations, and foreign governments. Most IIS work is funded on a reimbursable basis. The Corps of Engineers provides engineering and construction services, environmental restoration and management services, research and development assistance, management of water and land related natural resources, relief and recovery work, and other management and technical services.

The flexibility of the IIS program allows USACE to be able to assist partners with a large variety of missions. Buffalo District's typical IIS work is related to Facilities, Environmental Services, Dive Team, and Geographical Information Systems, but USACE can provide assistance in any areas where our project management, engineering, environmental, and other technical skills can be utilized.

For more information and to discuss how Buffalo District can be of assistance with your organizations goals, please contact the IIS Program:
