CC3 Adaptation - Sustainable Drainage

Development will not be permitted if it has an unacceptable effect on the water environment, including surface water and groundwater quality and quantity, river corridors and associated wetlands.

Development proposals will not be permitted unless they incorporate sustainable drainage systems (SUDS) appropriate to the local ground water and soil conditions, local drainage regimes and in accordance with the Groundwater Regulations. Where soil permeability is low, rainwater harvesting and/or green roofs should, where practicable, be integrated into the design of the development.

Where SUDS are used, they will be required, where appropriate and practicable, to deliver recreation and wildlife benefits.

Development proposals incorporating SUDS must include an agreement to ensure future management, maintenance and replacement, when necessary, of the SUDS structures.

Where it is not practicable to use SUDS, the development proposal will need to demonstrate that an appropriate alternative means of surface water drainage to ground watercourses or surface water sewers is incorporated.
