Avoid significant residual impacts* of turbidity on the habitats and the main fish functional zones of importance most sensitive to this pressure, under the influence of marine works, material extraction, dredging, dumping of dredged material, developments and land-based discharges *notable residual impacts within the meaning of environmental assessment N. B. 1: This objective targets the main fish functional zones of importance (FFZIs) and the following habitats: maerl beds, phanerogam meadows (eelgrass, posidonia, cymodocae), belts of rockweed, kelp and cystose, lithophyllum sidewalks, sabellarid bioconstructions and coralligenous (coastal and deep). N.B. 2: Maps of FFZIswill be produced as part of M004.

Avoid any new anthropogenic modification of the hydrographic conditions having a significant residual impact* on the current and sedimentology of the sectors at stake and in priority in the macro-tidal bays, areas of maximum current and sectors of hydraulic dunes * significant residual impacts in the sense of the environmental assessment

Limiting pressures and barriers to sea-land connectivity in estuaries and coastal lagoons

Limiting pressures and barriers to sea-land connectivity in estuaries and coastal lagoons

Ensuring an adequate volume of freshwater in the coastal sector throughout the year, including by reducing the levels of water abstraction (groundwater and surface water) at the catchment level

To preserve marine ecosystems, their functionalities and uses by ensuring a sufficient quantitative supply of fresh water in the coastal sector.

Preserve marine ecosystems and their functionality by controlling turbid discharges from maritime (dredging, aggregate extraction, etc.) and land-based (dewatering, dam flushing, etc.) activities.

Preserve areas with little or no impact through permanent modification of hydrographic processes, especially those hosting habitats with a key functional role / Reduce pressures impacting habitats and their functionalities
