Sustainable drainage systems (SuDS)
On 18 December 2014, the government issued a written statement in relation to sustainable drainage systems. Existing national planning policy is to be strengthened to make it clear the government expects sustainable drainage systems (SuDS) to be provided in new developments. The latest National Planning Policy Framework outlines these expectations which can be found under paragraph 155 here.
To this effect, where planning applications are for major development, the local planning authority must ensure that SuDS are put in place, unless demonstrated to be inappropriate.
A major development is defined as:
- a residential development: 10 dwellings or more or residential development with a site area of 0.5 hectares or more where the number of dwellings is not yet known
- a non-residential development: provision of a building or buildings where the total floor space to be created is 1000 square metres or more or where the floor area is not yet known, a site area of 1 hectare or more.
We encourage all applicants to use the EA pre-application service in order that drainage matters can be discussed and potentially agreed upon at this stage.
