A Project Partnership Agreement (PPA) is a legally binding agreement between the Government and a non-Federal sponsor (state, municipal government, flood control district, port authority, etc.) for construction of a water resources project. It describes the project and the responsibilities of the Government and the non-Federal sponsor in the cost sharing and execution of work.
Section 2003(c) of the Water Resources Development Act of 2007 states that every District of the Corps of Engineers will make all of their PPAs signed after November 8, 1997 available to the public through their website.
