The urban Community Rochefort Ocean wants to revive its port and the surrounding economic zone, despite strong constraints due to sea-river flooding risks of the river Charente. With Atelier Acturba as leader and ISL Engineering, Kalutere Polis will draft a development scheme. The assessment will focus on hydraulics, land use and building stock. On these bases, the consortium will propose a development strategy, specific regulations that could be adopted in a new and specific sector of the revised Plan for Flood Risk Prevention, as well as an action plan. Reinforcing cooperation among actors will be a key factor for success. November 2014.
