Key takeaways
  • The river-sea connection needs to be discussed within the framework of a total catchment area approach
  • It is recommendable to develop a Masterplan of the Bay and to take the different eco-systems of the catchment area into account
  • For communication, it is important to concentrate on the benefits of the different stakeholder groups concerned by the restoration
  • Undertake a specific definition of the objectives of the works i.e. climate change adaptation, nature protection, sustainable tourism, etc.
  • A better understanding of the functionality aspect of the river-sea connection is needed and defining the categories of users (fishermen, tourists, citizens, hotels, etc.)
  • The replacement of the bridge is not limited to the municipality area and is influencing the flow of traffic also in the wider region structures should be foreseen
