Cambridgeshire County Council is a Lead Local Flood Authority (LLFA) and as such is a statutory consultee to the planning process for surface water on all major developments. The consultation requirement and description of major development is detailed within the Town and Country Planning (Development Management Procedure Order). This applies to all new major planning applications. We are unable to provide comments to those sites which began or completed planning consultations before 15 April 2015.

Our role will be similar to the Environment Agency's (EA) previous role in advising on surface water drainage implications for proposed developments. New National Planning Practice Guidance and non statutory technical standards for sustainable drainage systems will aid our responses to consultations. The EA will still provide comments on fluvial and tidal flood risk from main rivers and the sea and will continue to discharge conditions and respond to reserved matters on sites where they previously made comments.

Flood and Water Supplementary Planning Document

Cambridgeshire County Council, in its capacity as LLFA endorsed the Cambridgeshire Flood & Water Supplementary Planning Document (SPD) on 14 July 2016. It is planned that the SPD will be adopted by the county’s five Local Planning Authorities (LPAs) in due course.

The SPD has been prepared in conjunction with the LPAs and other relevant stakeholders, to support the implementation of flood risk and water related policies in the Local Plans. In its role as a statutory consultee for surface water drainage, the LLFA will follow the guidance in this SPD. 

Advice to developers

Guidance is provided for developers. We recommend that developers use the Surface Water Guidance document below when completing surface water drainage strategies (possibly produced as part of an FRA if one is required). You are also strongly recommended to complete the Proforma document below whilst undertaking a surface water drainage strategy. This needs to be sent to the local planning authority. This will help streamline the process in assessing surface water drainage proposals and ensure that the correct information is submitted as part of the planning application.

Pre-application advice

To ensure viable and sustainable drainage systems for new developers it is always best to consider the drainage system for a new development from the outset. We offer advice and encourage you to discuss your plans with our officers prior to making a formal planning application submission.

If you wish to take up our pre-application service or would like to discuss comments made by the LLFA in response to a planning application, please see the charging schedule below (as there may be charge for this service).

If you require any further information please email [email protected]

Sustainable Drainage Systems (SuDS)

Sustainable Drainage Systems (SuDS) mimic natural drainage to manage surface water run-off from a development. SuDS allow for the collection, storage and treatment of surface water in order to reduce flood risk caused by development. It also helps to improve water quality. SuDS can also improve landscape amenity and biodiversity.

You can find more information on SuDS. An example of SuDS in Cambridgeshire is the Lamb Drove SuDS Showcase Project in Cambourne and you can view these documents below.
