From 15 April 2015 Norfolk County Council as Lead Local Flood Authority (LLFA) is a statutory consultee on all planning applications for major development. The LLFA is therefore required to comment on planning applications in respect of surface water drainage. This was previously the responsibility of the Environment Agency.
The changes that made the LLFA a statutory consultee role are detailed in the Town and Country Planning (Development Management Procedure) (England) Order 2015).
From 6 April 2015, planning policy and decisions on planning applications relating to major development are required to ensure that sustainable drainage systems (SuDS) are used for the management of surface water. The role of decision making on planning applications is the responsibility of Local Planning Authorities (LPAs).
Each year, the Lead Local Flood Authority (Norfolk) are required to report the levels of service in the role as Statutory Consultee to Planning to the Department for Communities and Local Government.

How to find a consultant
There are several Chartered Institutes and organisations who maintain lists or searchable directories of professional qualified consultants who can provide flooding, drainage and other environmental services to support planning applications.
A chartered civil engineer (qualified through the Chartered Institute of Civil Engineers (ICE)) would also be professionally qualified to undertake various assessments, however a searchable list of companies who employ chartered civil engineers isn't available.
Other local companies are also available however we don't maintain a list of these.
