A Flood Risk Assessment is required in the following instances:
- In Flood zone 1: Development of 1 hectare or greater
- In Flood zones 2 and 3: All development
However, prior to producing a Flood Risk Assessment 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.
Identify and assess the risks to and from the development from all forms of flooding; and
Demonstrate how these risks will be managed; taking account of climate change
Identify opportunities to reduce the probability and consequences of flooding
Demonstrate that safe access to and from developments in areas at risk of flooding can be achieved
Integrate surface water management systems in to the design of the development which may include, for example, Sustainable Urban Drainage Systems (SuDS)
Sustainable Drainage Systems (SuDS) Design Statement
Guidance is provided on the requirement that major applications with surface water drainage submit a SuDS Design Statement. Where a Flood Risk Assessment is also required, these can be integrated into a single document.
