As in the rest of France, the small size of the commune of Cayenne (only 23.6 km2), which does not cover the entire urban area of Cayenne, has led to the creation of an intercommunal authority which groups Cayenne and 5 suburban communes: the communauté d'agglomération du Centre Littoral (5,087 km2). Marie-Laure Phinéra-Horth has been president of the communauté d'agglomération du Centre Littoral since 2014. This intercommunal structure, which levies its own taxes, is the sole authority in charge of refuse collection, water supply and sewage treatment, urban planning, and public transport over the 5,087 km2 of Cayenne and its suburbs.
