For each operation, an agreement between the Prefect and the President of the Assembly of French Guyana or the Departmental Council of Mayotte defines the content of the project management powers entrusted to the local authority and the organisation of the project management. These operations are subject to technical and financial control by the State in its capacity as project owner. The exercise of the powers entrusted to the local authority ends with the discharge issued by the relevant State services, after acceptance of the work.
