Intergovernmental Agreements (IGAs)

An intergovernmental agreement (IGA) is any agreement that involves or is made between two or more governments in cooperation to solve problems of mutual concern. Intergovernmental agreements can be made between or among a broad range of governmental or quasi-governmental entities. Governments use IGAs for cooperative planning, development review, resource sharing, joint planning commissions, building inspection services, and more.
