The EU INTERREG programme has recently consulted on the effect that rising sea levels, coupled with spring tides, could have on Lewes and the lower Ouse valley.
The Society has welcomed the consultation as it seeks to address longer term issues and builds on planning policy documents and both coastal and river basin management plans.
Whilst the consultation notes that sea level rises are likely to be greater in the next 500 years than in the preceding 500 years, experts have suggested that in the next 50 years flooding in Lewes is more likely to arise from local factors than an increase in sea level. However it is clearly important that any new development on the flood plain should be resilient to any flood risk.
