Why is an area that is adequately defended by a defence that is in good condition still considered as being in the high risk zone?
The SFRA considers the residual risk which is a product of probability and consequence. In the case of South Essex, the probability of flooding is very low due to the high standard of protection. However, failure of the flood defences could potentially have catastrophic consequences both locally and nationally. Therefore the residual risk is considered high and its effective continued management is required. To diminish the residual risk, the approach in South Essex and advocated in PPS25 is to gradually reduce the consequences by managing flood risk through a variety of flood mitigation measures, including spatial planning.
