Cambridgeshire LLFA welcome the consideration of using flood risk management measures to promote biodiversity in the Village Design Guide SPD. It should further promote sustainable drainage techniques (SuDS).
SuDS are in approach to manage surface water runoff which seeks to mimic natural drainage systems and retain water on or near the site as apposed to traditional drainage approaches which involves piping water off site as quickly as possible. SuDS offer significant advantages over conventional piped drainage systems in reducing flood risk by attenuations the rate and quantity of surface water run-off from a site, promoting groundwork recharge, and improving water quality and amenity.
The variety of SuDS techniques available means that virtually any development should be able to include a scheme based around these principles.
