MIDDLE FEN AND MERE INTERNAL DRAINAGE BOARD

POLICY STATEMENT ON FLOOD PROTECTION AND WATER LEVEL MANAGEMENT

1.      INTRODUCTION

            Purpose

1.1.      This policy statement has been prepared by Middle Fen and Mere Internal Drainage Board to provide a public statement of the Board’s approach to its management of flood risk and water levels in its area.
            Background
1.2.      The Department for Environment, Food and Rural Affairs (formerly know as The Ministry of Agriculture, Fisheries and Food) has policy responsibility for flood and coastal defence in England.  However, delivery is the responsibility Middle Fen and Mere Internal Drainage Board.  The Board maintained infrastructure is shown in para 3.2. below.

1.3.      The Government has published a policy aim and three objectives for flood and coastal defence¹.  To ensure a more certain delivery of the aim and objectives by the individual operating authorities the Government has published a series of high level targets².  The first target requires each operating authority to publish a policy statement setting out their plans for delivering the Government’s policy aim and objectives in their area.  This will include an assessment of the risk of flooding in their area and what plans they have to reduce that risk.

1.4.      This policy statement fulfils that requirement.  We are providing a copy to the Department for Environment, Food and Rural Affairs, the Department of the Environment, Transport and the Regions, the Environment Agency and local authorities in the District.  Copies are also available from the Board’s offices at The Drainage Office, Main Street, Prickwillow, Ely, Cambridgeshire, CB7 4UN.

2.      HOW THE BOARD WILL DELIVER THE GOVERNMENT’S POLICY AIM AND OBJECTIVES

2.1.      Middle Fen and Mere Internal Drainage Board supports the Government’s aim and objectives for flood and coastal defence.  Our policy and approach will be consistent with them.

Policy Aim
To reduce the risk to people and the developed and natural environment from flooding and coastal erosion by encouraging the provision of technically, environmentally and economically sound and sustainable defence measures.
Section 3 below sets out our plans for reducing or managing the flood risk in the Board’s District.

Objective (a): To encourage the provision of adequate and cost effective flood warning systems.
The Board will assist the Environment Agency wherever possible in its provision of adequate and cost effective flood warning systems.  Integrating with the Agency in response to flood emergencies and participating as necessary in exercises to develop and test emergency response procedures.


Objective (b): To encourage the provision of adequate, economically, technically and environmentally sound and sustainable flood and coastal defences.
In meeting its obligations the Board will consider its activities within the wider natural and developed environment seeking to ensure the avoidance of any adverse impact.  It will equally co-operate with other drainage authorities and organisations to ensure adverse impacts on the drainage district do not arise as a result of other activities.

The Board will carry out its maintenance and improvement works in an efficient and cost effective way and where appropriate use best practice and accessing appropriately qualified advice when necessary.

To achieve this the Board will encourage the provision of adequate, economically, technically and environmentally sound and sustainable flood protection and water level management measures and seek to control that development which could increase the risk of flooding.

Within  the drainage district  potentially all  the area is at some risk to flooding and the Board will seek to retain this risk at acceptable levels through appropriate improvements and the implementation of a sound maintenance strategy.  They will also seek to ensure that the Environment Agency maintains at a satisfactory standard any flood defences which also afford protection to the District.

Objective (c): To discourage inappropriate development in areas at risk from flooding.
The potential impact on flood risk through future development in the Drainage District, or in the wider catchment draining to the District, is fully recognised by the Board and it will take an active role in the assessment of structure planning, local plans and individual applications to ensure flood risk is not increased.  Where appropriate the Board will secure from Developers and other direct beneficiaries, contributions to cover the cost of both immediate and longer term works necessary in ensuring that any potential increase in flood risk is removed.

3.3.     REGULATION & ACTIVITIES

The Board will exercise as required its powers under The Land Drainage Act 1991 and its Byelaws to ensure that activities in and alongside its drainage system do not reduce flood protection standards and unnecessarily increase flood risk.

3.4.      Standard of Protection
Through the operation and maintenance of the pumping stations and the channel system the Board seek to maintain a general standard capable to providing flood protection to agricultural land and developed areas of 1 in 20 and 1 in 100 years respectively.  This likely return period cannot be taken literally and should be considered as a chance of some overspilling from the system taking place each year as being 5% and 1% respectively.
Areas which are more vulnerable due to the particular local circumstances are the four pumping station basins as these are the lowest areas of the District.

3.5.      Management of Flood Risks
The Board monitor the condition of its pumping stations and watercourses, particularly those designated as critical, overspilling from which could affect property.  Consistent with the established need a routine maintenance programme is in place to ensure that the condition of the assets is commensurate with the standards of protection which are sought.  Where standards are not at the policy level, improvement works, where they can be demonstrated to meet with DEFRA criteria, will be considered and undertaken as appropriate. The Board welcome from its agricultural ratepayers, special levy councils and members of the public any comments on the condition of its system which could lead to any increased flood risk.

3.6.      Publicity
The  Board  will  seek to  promote the  need for  works  in its District  and create  a rational understanding among people who live and work in it as to what the flood risk is and the efforts made to control it.  They will also seek to achieve directly and through local councils a culture within which the watercourses are seen as vital to controlling flood risk, whilst providing an interesting aquatic habitat and dissuade abuse of them through dumping waste or obstructing flows in other ways.  The Board will publish its proposed annual programme of capital and maintenance work which will be available on request from the Board’s offices at Prickwillow.

4.      ENVIRONMENTAL MEASURES

4.1.      The Middle Fen and Mere Internal Drainage Board has nature conservation duties under The Land Drainage Act 1991, The Wildlife and Countryside Act 1981 and as a competent authority under the Conservation (Natural Habitats C) Regulation 1994.  The Board will fulfill these in a positive way.
            The Board’s watercourse maintenance work of vegetation control and de-silting is a vital and   routine  requirement.   Whilst   inevitably  some   short  term  impact  will   arise,   this management is essential also to maintain the diverse aquatic habitat in the District.  The Board maintain only a small proportion of the total watercourse length in the District, the significant majority being the responsibility of riparian land owners.

When carrying out works, be it maintenance or improvement and consistent with the need to maintain satisfactory flood protection standards, we will aim to
            * avoid any unnecessary or long term damage to all the natural habitats
            * ensure no net loss of habitats covered by Biodiversity Action Plans, monitoring any gains
                and losses and reporting annually to the Environment Agency
            * take appropriate opportunities to enhance habitats.

4.2.      The Board will play its full role in sustaining the water level plan prepared for the SSSIs and in conjunction with English Nature and other interested parties, review the plan in accordance with DEFRA guidance.
