Type of application
  • Sequential Test - All relevant applications (changes of use (unless it is to a caravan / mobile home park) and minor applications such as house extensions, adverts, air conditioning units etc are excluded) within flood zones 2, 3a and 3b. See Assessing flood risk|External link.
  • Exception test – following the application of the Sequential Test, an Exception Test may be required.
Geographic locations where this information is requiredFlood Zones 2, 3a and 3b
What information is requiredThe Sequential Test must establish that there are no other reasonably available sites appropriate for the proposed development in areas with a lower probability of flooding as detailed in paragraph 101 of the National Planning Policy Framework . Guidance on the Exceptions test can be found in the National Planning Policy Framework and the Technical Guidance to the National Planning Policy Framework.
Where to look for further assistance

See 'Further Information'.

If, after reading the Further Information you are still unsure about the information to submit please contact the Council's Drainage Engineer on (01422) 392168 and the Environment Agency on (03708) 506506. In addition the flood risk areas can be viewed at Environment Agency Flood Risk Maps|External link.

Further information

Prior to producing a Flood Risk Assessments|External link it is advisable to first ensure that the Sequential Test has been passed. If there are other available sites at a lower probability of flooding that could accommodate the proposed development then the Sequential Test will be failed and a Flood Risk Assessment would be irrelevant. Further information on the Sequential Test can be found in the National Planning Policy Framework Section 10 Paragraphs 100-102 and the Technical Guidance to the National Planning Policy Framework (Paragraphs 3-5).

If, following the application of a Sequential Test, it is not possible to locate the development in a lower flood risk zone, an Exception Test may also be required (see National Planning Policy Framework Section 10 paragraph 102 and page 2- 8 of the Technical Guidance to the National Planning Policy Framework).

Evidence that the Sequential Test has been passed, and the Exception Test requirements have been satisfied, where applicable, will be added to the planning file.
