Detailed Design 9.8 Amenity

Confirming integrated SuDS design

Amenity is one of the four pillars of SuDS

interpretation and judgement.

Amenity focuses on the usefulness and
aesthetic elements of SuDS design
associated with features ‘at or near the

considered at both Concept and Outline
design stages but some finer aspects of value
will be enhanced by detail design at stage.

An evaluation of the successful integration of
amenity uses the design criteria set out in
Concept Design.
