The Aunis Atlantic Community of Communes, as part of the development of the PLUi, is to prepare communal wetland inventories in 17of the 20 municipalities in its territory. The main objective is to preserve these spaces from any form of urbanisation. The future zoning of the PLUi will take into account the inventories made.The production of wetland inventories will be carried out in accordance with the provisions and methodology recommended by the Local Water Commission (CLE) of the Sèvre Niortaise Marais Poitevin Water Management and Management Scheme (SAGE).The wetland inventory of the 17 communes will be carried out in two years between March 2017 and March 2019.
