Flood Risk Assessment - What is the Exceptions Test?

The Exceptions Test is included (if needed) in our standard Flood Risk Assessment report. Please contact us for a quotation. Our methods meets with near 100% acceptance.

The Exception Test provides a method of managing flood risk while still allowing necessary development to occur. The Exception Test is only appropriate for use when there are large areas in Flood Zones 2 and 3, “where the Sequential Test alone cannot deliver acceptable sites, but where some continuing development is necessary for wider sustainable development reasons, taking into account the need to avoid social or economic blight”.

For the Exception Test to be passed:

a. It must be demonstrated that the development provides wider sustainability benefits to the community that outweigh flood risk, informed by a SFRA where one has been prepared.

b. The development should be on developable previously-developed land or, if it is not on previously developed land, that there are no reasonable alternative sites on developable previously-developed land; and

c. A FRA must demonstrate that the development will be safe, without increasing flood

Please feel free to contact the office for an informal discussion regarding your requirements.

In practice the exceptions test relates to larger 5 home plus developments, where meaning sustainability measures can be incorporated that will provide "wider" benefits. However, it is generally the case that even a small single unit development the exception test will have to be carried out. Carrying out the exceptions to in the right manner can make or break an application.

The exceptions test for a small site would be conducted as follows.

Wider Sustainability Benefits - "The proposed development increases housing density in the area, which will lead to a reduction in transport related emissions. The development will exceed statutory minima with regards to energy efficiency. In line with the code for sustainable homes provisions are made for home working with a study / office area being provided for each dwelling, again potentially reducing transport related emissions".
