Development Control and Regulation

By regulating development we can secure the efficient working of the drainage system now and for the future. This is done by reasonable application of the Board’s Byelaws and the Land Drainage Act 1991. We aim to work closely with Landowners, Developers and Local Planning Authorities as well as with other Risk Management Authorities, such as the Environment Agency and Lead Local Flood Authorities.

Planning and Byelaw Strategy

The Group’s Planning and Byelaw Strategy seeks to communicate the way in which the Board undertakes its flood risk and water management functions and to highlight the policy framework that supports delivery of this work. Specifically this strategy provides:

  • A public statement of the Boards rationale and approach to its management of flood risk and water levels in its area, in-line with National and Local Policy;
  • Guidance on how the Board will review and comment on planning applications within its Internal Drainage District (“IDD”), or that have the potential to significantly impact its IDD;
  • Guidance to organisations and individuals on the Boards regulatory requirements and processes;
  • Information on the policies against which the Board will assess and determine applications.
