Climate actions
To avoid hydrogeological instability phenomena it is necessary to ensure the continuity of the outflow routes between upstream and downstream of the newly built roads, by means of side rails and suitable crossing structures. It is necessary to avoid blocking the roads of outflow at any point of the drainage network to prevent the formation of stagnant zones. Public and private ditches must be kept under maintenance, they can be neither eliminated nor reduced in their size without providing adequate compensation measures. Interventions on the sewerage system or closure of existing ditches are prohibited, except for justified needs of public interest and their reconstruction must provide for a suitable new configuration. Urban development plans, need for new construction areas, constant monitoring.
