The design guide is primarily intended for use by developers and their consultants where they are seeking adoption of SUDS by Cambridge City Council within open space of new developments. It sets out the design and adoption requirements that the City Council require to ensure a smooth and satisfactory adoption process. Included within the guide are design considerations and essential principles that developers and their consultants will need to take into account when designing and constructing SUDS. A number of specific SUDS methods are studied in more detail, including ponds and wetlands, retention and infiltration basins, swales and filter strips, filter drains, canals rills and channel systems. The aim is to ensure that high quality SUDS are delivered that reduce flood risk are easy to maintain and maximise the landscape, amenity and biodiversity potential of the scheme.
