W4: SuDS

Sustainable Drainage systems should be designed and implemented in ways that deliver multiple benefits, including improvements in water quality, biodiversity, amenity and recreation. Where practicable, SuDS should be designed to ensure the sustainable drainage networks have the additional capacity required to cope with infrequent adverse weather conditions and therefore reduce flood risk.

Development should aim to achieve Greenfield run-off rates and ensure that surface water run-off is managed as close to its source as possible.

Development must utilise the most sustainable forms of drainage systems in accordance with the SuDS hierarchy. The Council will resist the use of underground holding tanks.

The provision of balancing ponds as part of an area of public open space for recreation or wildlife should be designed to ensure the safety of users of the space.

Where SuDs are provided as part of a development, applicants should detail how it will be managed and maintained in the long term.

The Council will require retrofitting of sustainable drainage systems (SuDS) and other water management measures where-ever possible, to improve water quality and reduce the responsiveness of catchments in the Borough to high intensity rainfall events.
