Historical Flooding Incidents

Improving our knowledge and understanding of historic flooding events across the borough will help us to focus our resources and funding towards those areas most susceptible to flooding.

We are working to set up a webpage to allow you to upload information you have in relation to current and historical flooding incidents.
