The role of the parishes
• If you live or you own property that is next to watercourse that flows through your property you are a 'riparian landowner' and you have responsibility to pass the water downstream unimpeded
• Farmers, major land owners and some individuals who are riparian landowners do this themselves. Other elderly or less able residents may struggle…
• COMMUNITY RESILIENCE Parishes can help by forming community flood groups –- to identify flood areas, help keep watercourses clear, help in emergencies with flood defences, producing emergency/flood plans, making sure people are safe. OCC officers and Vale council can attend meetings, provide advice. Grant ££ available!
