Each Commune must have their own "J.A.L.", which is made up of 7 dignitaries who are chosen by a public vote for an elected period of a year. The J.A.L. must provide support to the public services, such as environmental cleaning, public health, education, public works (both future and present), mass transit and community organization. They are able, in the case of public works, to indicate the priority of various works to the mayor, propose investment plans and must contribute these plans to the development of the Municipality.
