Public Consultation Survey - Local Flood Risk Management

Closed 16 Jan 2023

Opened 19 Dec 2022


What is the Local Flood Risk Management Strategy?

This Local Flood Risk Management Strategy is a high-level strategic document outlining Sutton’s approach to Flood Risk throughout the next 6 years.

Sutton as Lead Local Flood Authority are required by the Flood and Water Management Act (2010) to develop, maintain, apply and monitor a Local Strategy for flood risk management.

The strategy explains how flood risk will be mitigated across the whole of Sutton, including a summary of the past and present flood risk. It also acknowledges the impacts of climate change and proposes measures to ensure that Sutton can be more resilient and sustainable in its flood risk management practices in the future.

Climate change means flooding could affect everyone

Climate change affects all of us, with flooding predicted to become more frequent and intense due to climate change, as we experienced in the extreme rainfall events during July and August last year.

This means that even if you are not currently at flood risk, then you may be in years to come. Also, if you are currently at risk of flooding, then your risk could become more severe and so this is important to consider when planning for the future.

About Flooding
There are various types of flooding that locations across Sutton are at risk from. These include flooding from fluvial sources, ordinary watercourses, groundwater, surface water, and sewers. This Infographic provides further detail on each of these types of flooding.

Your feedback into the Local Flood Risk Management Strategy
