Detailed Design 9.0

Detailed Design

The SuDS strategy will be reasonably fixed by Detailed Design stage. The
management train, selection of SuDS features and general means of storing

runoff will have been evaluated and defined at earlier design stages.

The development and refinement of Concept and Outline designs at Detailed

Design stage will demonstrate that the project objectives can be delivered
upon and will be presented with either the detailed planning application or

to discharge planning conditions, or reverved matters, depending upon the
requirements of the LPA.

Competent design details ensure that runoff
is collected, conveyed, cleaned, stored,
controlled and discharged from site in an
effective manner that provides wider
benefits.

Failure of individual elements of the design
can:
67 ■ invalidate expected storage volumes and

flow rates
■ prevent adequate treatment

■ negatively impact or miss opportunities to
contribute to amenity use

■ create hazards to wildlife or miss
opportunities to support biodiversity
■ cause local ponding, flooding and

inconvenience to the public
■ increase maintenance difficulty and cost.
