• Recovering marine natural habitats
110 ha affected but 94% of the surface low to very low sensitivity (104 ha).

The hydro-sedimentary impact is indirect (currents, transportation)
• On worksites : moderate risks on the Banc des Lataniers : ≤ 3 cm of coverage.
• After construction : low risks
• Material washed down by the gullies : no impact. The project does not modify the spreading of MES (Suspended matter) washed down by the gullies.

• Reinforcing the corridors

• Integrated in the engineering works/by specific constructions
• Eco-design of 6 viaduct piers around the challenging area of La Pointe du Gouffre.
• Design of modules of eco-reef.
