The region has a basin management plan {piano di bacino) but it is not effectively integrated with other planning instruments. This is particularly urgent given the Lagoon’s highly polluted sediment, which is at times sufficiently polluted to be designated as toxic waste under national legislation (and thus subject to special removal and disposal procedures). The Lagoon sediment is nonetheless an important resource for morphological reconstruction {e.g. salt marshes) and littoral regeneration {e.g. creation of parks along the coastal zone). However, no integrated policy governs water quality concerns stemming from dredging for navigation purposes, which stirs up sediment and re-introduces it into the water column.
