Coordination Agreements

In basins with multiple GSPs, a single Coordination Agreement must be submitted with the GSPs to DWR. The coordination agreement ensures that GSPs are developed and implemented using consistent data, methodologies, and objectives.

The Coordination Agreement must demonstrate how multiple GSPs will jointly achieve the basin’s sustainability goal. Additionally, it must include the responsibilities of each GSA in the basin; the procedures for exchanging information and resolving conflicts; and a description of the data, methodologies, and assumptions used in GSP development.
