2.4.3 Flood Resilience

Three key principles that should be adopted by regional authorities, local authorities, developers, and their agents when considering flood risk are as follows:

  • Avoid the risk, where possible,
  • Substitute less vulnerable uses, where avoidance is not possible, and
  • Mitigate and manage the risk, where avoidance and substitution are not possible

A Strategic Flood Risk Assessment has been carried out for the County as part of the Strategic Environmental Assessment which identified the areas at risk to flooding and appropriate policy response, which includes a requirement that a Flood Risk Assessment is carried out for any development proposal, where flood risk may be an issue. This assessment shall be appropriate to the scale and nature of risk to and from the potential development and shall consider the impact of climate change (See Chapter 10 Infrastructure). 

The Council will continue to apply the Sustainable Urban Design Drainage Systems when assessing development proposals.  Examples of SUDS include green roofs, soakaways, swales, infiltration trenches ponds and wetlands. SUDS provide areas within the built environment where the natural processes of rainwater interception, storage and infiltration can take place.
