Lead Local Flood Authority (LLFA)

On the 24 March 2015, the National Government laid out a statutory instrument to make the Lead Local Flood Authority (LLFA) a statutory consultee in planning for all major developments in relation to the management of surface water drainage from the 15 April 2015.

The LLFA for Stevenage is Hertfordshire County Council and they will advise us as the Local Planning Authority (LPA) on whether the proposed drainage scheme complies with the relevant technical standards and policies. The decision on whether the submitted drainage scheme is acceptable is down to us, as the determining authority.

Formal planning applications

We will consult with the LLFA and submit to them the drainage scheme which is provided as part of your planning application submission. If any additional information is requested by the LLFA, this has to be passed onto us as the LPA who will then forward it onto the LLFA. This is because the LLFA will not accept any new information from you as the applicant and/or agent directly.

Pre-application service

Hertfordshire County Council provide a pre-application service which is subject to a fee and the submission of the relevant pre-application form. 

Works affecting ordinary watercourses

It is important to take note that whilst the LLFA is not a statutory consultee where development sites contain Ordinary Watercourses, the LLFA is the regulatory authority under Section 23 of the Land Drainage Act 1991.

Regardless of any planning permission, you may also require prior written consent from the LLFA.

Hertfordshire County Council provide guidance on applying for consent for works on Ordinary Watercourses.

You are strongly advised that if the application site contains an ordinary watercourse, to contact Hertfordshire County Council’s Flood Risk Management Team directly. Their contact details are as follows:
