The regional development plan sets out the fundamental guidelines for the development, protection and enhancement of the coastline.
It takes the place, for the sectors that it determines, of a scheme for the development of the sea within the meaning of article 57 of law no. 83-8 of 7 January 1983 relating to the division of powers between municipalities, departments, regions and the State.
As such, it defines for these sectors the guidelines, vocations, principles, measures and particular constraints provided for in this same article and includes graphic documents representing the vocations, protections, developments and facilities planned.
In the communes included in the list drawn up in application of article L. 321-15 of the Environment Code, it includes guidelines for adapting territories to the retreating coastline. It may identify sectors intended to accommodate installations and constructions for relocation projects that are located outside the coastal strip defined in article L. 121-45 of the town planning code, areas delimited in application of article L. 121-22-2 of the same code and remarkable coastal areas.
The regional development plan may not include sectors covered by the individualised chapter of a territorial coherence plan that is equivalent to a sea enhancement plan.
