Under Schedule 3 of the Flood and Water Management Act 2010, provision was made to ensure that sustainable drainage systems are delivered in a way which prioritises SuDS over conventional drainage and stipulates that developers ensure their design allows for future maintenance.
We are responsible for ensuring that sustainable drainage systems should be provided, unless demonstrated to be inappropriate with the Lead Local Flood Authority (LLFA) providing technical guidance and acting as a statutory consultee.
The duty will apply to major developments which can be defined as any of the following:
- a residential development of 10 or more homes
- a residential development on a site of at least 0.5 hectares
- a non-residential development on a site of at least 1 hectare
- creation or change of use of a commercial development, where the floorspace is 1,000 square metres or more.
