The Southeast Nebraska Development District (SENDD) is a multi-county economic development organization authorized by the U.S. Department of Commerce-Economic Development Administration (EDA). This voluntary association of counties and municipalities was formed under the Interlocal Cooperation Act to identify common problems, their solutions and to provide continuing support for efficient and effective government among its members and encourages cooperation between local government officials, community based organizations and the private sector. A Board of Directors represented by elected officials, businesses, economic development organizations and regional stakeholders makes policy decisions and sets direction for the organization.

Originally created as the Vision-17 Areawide Planning Agency in 1974, merging with the Southeast Nebraska Council of Governments (SENCOG) in 1982 and expanding into 7-new counties in 2005, SENDD membership currently includes the following 15 counties, and many of the 139 municipalities of Cass, Fillmore, Gage, Jefferson, Johnson, Nemaha, Otoe, Pawnee, Polk, Richardson, Saline, Saunders, Seward, Thayer, and York Counties.
