32 Flood management

The Council will support development that seeks to avoid flood risk to people and property and manages residual risk by applying the Sequential Test and, if necessary, the Exception Test as set out in the NPPF.

The Council’s Strategic Flood Risk Assessment should be used as a starting point regarding local flood risk guidance.

In addition to the requirements set out in the NPPF, the Council will require site-specific flood risk assessments for development on:

  • Sites where drainage problems have been identified by the Council;
  • The Washlands Flood Storage Area (FSA); and
  • Sites deemed necessary by the Council as a Lead Local Flood Authority.

The Council will seek to reduce the risk from surface water flooding by requiring development proposals to:

  • Reduce surface water runoff by providing sustainable drainage systems (SuDS), unless there are practical reasons for not doing so; and
  • Ensure that proposals for SuDS apply the London Plan drainage hierarchy achieving greenfield run-off rates, where feasible, and include clear arrangements for ongoing maintenance over the lifetime of the development.

The Council will expected developments to identify reasonable opportunities for flood risk reduction measures and resilient design and construction and not increase the risk of flooding.

The Council will seek financial contributions towards the anticipated costs of flood risk management infrastructure required to protect the proposed development over its lifetime.
