Surface water management plans
Current Surface Water Management Plans
- Bishops Cleeve, Southam and Woodmancote
- Gloucester, Churchdown and Innsworth
Since the devastating flooding in 2007 Gloucestershire County Council has been working with its local flood risk management partners to better understand and alleviate flooding in Gloucestershire. These include Gloucestershire Roads, the six District Councils, the Environment Agency, Severn Trent Water, Thames Water and the Lower Severn Internal Drainage Board.
A key part of this approach is to look at areas most vulnerable to surface water flooding.
What is surface water?
Surface water is water collecting on the ground after heavy rain causing flooding people, their properties, and other infrastructure (e.g. roads)
What is a Surface Water Management Plan?
A Surface Water Management Plan (SWMP) is a tool to identify areas more vulnerable to surface water flooding, and to identify measures to reduce the flooding, recognising that it is not economically viable to eliminate flooding altogether.
How is a SWMP produced?
The Department for Environment, Food and Rural Affairs (Defra) has produced national guidanceOpens new window on how to undertake a SWMP and we are using this guidance to inform our approach for SWMPs.
A summary of the key steps involved in undertaking a SWMP are:
- establish a partnership group involving the local partners with responsibility for managing flooding in the area
- establish an engagement plan, outlining other individuals and organisations who should be engaged during the course of the SWMP
- produce a model of the entire study area which represents all runoff entering and within the study area, and includes a representation of all public sewers and watercourses
- in the locations most vulnerable to flooding from surface runoff and ordinary watercourses identify and assess measures which can be taken to reduce flooding, and
- produce an action plan for the areas most vulnerable to flooding from surface runoff and ordinary watercourses, outlining the preferred measures to reduce flooding, next steps and responsibilities, and potential funding sources to implement the recommended measures
In addition to the action plans outputs from the SWMP can be used by spatial planners as part of the evidence base to support strategic planning. The outputs can also be used by emergency planners in preparing their Multi-Agency Flood Plans.

Preliminary Flood Risk Assessment
Under the EC Floods Directive, which has been transposed into UK law through the Flood Risk Regulations (2009), Gloucestershire County Council as Lead Local Flood Authority undertook a Preliminary Flood Risk Assessment (PFRA) to assess the harmful consequences of past and potential future flooding, and to identify areas of significant flood risk.

In 2017, Gloucestershire County Council undertook a review of their PFRA in accordance with the EU Floods Directive 6 year cycle. The resulting Addendum can be found in the link below:
