OW5: FLOODING AND DRAINAGE
New development should be designed to take full account of any existing flood risk, irrespective of the source of flooding. Where a site or its immediate surroundings have been identified to be at flood risk, all opportunities to reduce the identified risk should be investigated at the master planning stage of design and subsequently incorporated at the detailed design stage.
It is essential that the drainage scheme proposed to support new development:
- protects people and property on the development site from flooding; and
- does not create any additional flood risk outside of the development in any part of the catchment, either upstream or downstream.
Planning permission should only be granted for new development subject to a condition that:
- no development shall commence until full details of the proposed drainage schemes for surface and foul water (including details of their routing, design, and subsequent management and maintenance) have been submitted to and approved by the planning authority; and
- no building shall be occupied until the drainage schemes have been implemented in accordance with the approved details.
This shall apply to all built development for active use with the exception of residential extensions which do not propose additional bedrooms and/or bathrooms.
