Sustainable Drainage Systems Major Design Guidance

This advice sets out the requirements that the LLFA has for drainage strategies and surface water management provisions associated with applications for major development.

Standard 5: amenity

The applicant must provide a section within the Drainage Strategy or a standalone document confirming how this standard has been met.

Whilst the wider amenity benefits are outside the LLFA’s remit, it remains a functional part of the principles of SuDS and therefore, it should be incorporated into drainage designs.

The specific requirements of this standard may be assessed by other consultees.

Managing surface water through above ground multifunctional SuDS features, for example:  green roofs, vegetated swales, SuDS planters, raingardens, attenuating tree pits or permeable paving, contributes towards amenity value.
