Sustainable drainage systems (SuDS) planning advice

Surrey County Council in its capacity as Lead Local Flood Authority (LLFA) is a statutory consultee on surface water drainage for all new major developments, as set out in the Town and County Planning (Development Management Procedure) (England) Order 2015 (PDF). The order also sets out the consultation requirement and description of Major Development.

In order to assess each application we follow the principles set out in the DEFRA National Standards for Sustainable Drainage (PDF).

Working in partnership with the eleven other local planning authorities in Surrey, we have prepared a guidance document which provides our advice regarding meeting the requirements for the National Standards, the evidence required and what our standard conditions may be. The following documents are available to download and we would recommend that those are taken into consideration before submitting a planning application.

Surrey County Council also offers pre-application advice to help you submit the best surface water drainage strategy possible; full details and applicable fees are available in the attached document.

For guidance for integrating master planning sustainable drainage into developments see Water People Places document prepared by the Lead Local Flood Authorities in South East England which includes Surrey County Council.
