BSUI3 Managing Flood Risk

Proposals requiring a Flood Risk Assessment must demonstrate that the development will be resistant and resilient to all relevant sources of flooding including surface water. Proposed development must pass the sequential and exceptions test as required by national policy. The design and layout of proposals requiring a Flood Risk Assessment as set out in paragraph 6.7.37 must contribute to flood risk management and reduction and:

  1. minimise the risk of flooding on site and not increase the risk of flooding elsewhere;
  2. wherever possible, reduce flood risk overall;
  3. ensure a dry means of escape;
  4. achieve appropriate finished floor levels which should be at least 300mm above the modelled 1 in 100 year plus climate change flood level; and
  5. not create new basement dwellings in areas of high flood risk.

Proposals that would fail to make appropriate provision for flood risk mitigation, or which would increase the risk or consequences of flooding, will be refused.

Opportunities will be sought from the redevelopment of sites in functional floodplain (flood zone 3b) to restore the natural function and storage capacity of the floodplain. Proposals that result in an increase in natural flood storage capacity and the environmental quality of the watercourse, will be encouraged.
