A Flood Free Future for Lewes

This is a Friends of Lewes initiative in support of measures necessary to avoid future surface water flooding in Lewes. In line with our current Goals of improving the environment and mitigating the risks resulting from Climate Change along with increasing flows of surface runoff, the Friends of Lewes will work with partners in support of the measures agreed by the risk management authorities (RMAs).

We welcome the new Environment Agency (2020) – National Flood and Coastal Erosion Risk Management Strategy for England, with its key long term aims of:

  • enabling development of climate resilient places which avoid inappropriate floodplain development and use nature based solutions to address surface water runoff local to its source
  • ensuring new developments and infrastructure are resilient to flooding
  • developing communities ready and able to respond and adapt to flooding

We have links with The Aquifer Partnership (TAP), which is dedicated to protecting our local aquifer which holds our groundwater. TAP’s projects include making rainscapes in towns to catch pollution and hold back floodwaters:

Policy on Development in the Floodplain

Following the very successful Friends of Lewes 25th Floods Anniversary Exhibition, we received a considerable amount of feedback that Lewes residents didn’t want any more homes to be built in the floodplain. In response we have developed a policy position on development in the floodplain which we have sent to the South Downs National Park Authority in response to their latest version of the SDNP Local Plan.
