A development council brings together representatives of the economic, social, cultural and associative sectors of the Aix-Marseille-Provence metropolitan area. It is freely organised. It is consulted on the main orientations of the Aix-Marseille-Provence metropolitan area, on forward-looking and planning documents, and on the design and evaluation of local policies to promote the sustainable development of the area. It may give its opinion or be consulted on any other issue relating to the metropolis.
An annual activity report is drawn up by the development council and examined by the metropolitan council.
The operating procedures of the development council are determined by the internal regulations of the metropolitan council. Membership of this council may not give rise to any form of remuneration.
