DM24: Managing and Reducing Flood Risk
- The Council will ensure that all proposals for new development avoid and reduce the risk of flooding to future occupants and do not increase the risk of flooding.
- All proposals for new development within Flood Zone 2 and 3a will be required to provide sufficient evidence for the Council to assess whether the requirements of the Sequential Test and Exception Test, where required, have been satisfied. Proposals must be informed by a site specific Flood Risk Assessment (FRA) taking account of all potential sources of flooding and should:
- Demonstrate the application of a sequential approach for the development of individual sites to ensure that the most vulnerable land uses are located in areas of the site that are at lowest risk of flooding;
- Preserve overland flood and flow routes and ensure there is no net loss of flood storage. Adequate flood storage and compensation should be provided on site, or if this is not possible, provided off site where circumstances allow;
- Where appropriate, set out the mitigation measures that will be incorporated on site to manage residual flood risk including:
- Finished floor levels set no lower than 300mm above the 1 in 100 chance in any given year, including an allowance for climate change, flood level; and
- Ensure safe access and egress for future users of the development or an appropriate emergency evacuation plan.
- Contribute to naturalising watercourses where opportunities arise.
- All proposals for new development will be required to:
- Manage and reduce surface water run-off; and
- Manage water and waste water discharges.
- With the exception of water compatible uses and essential infrastructure, development in areas designated in Haringey’s Strategic Flood Risk Assessment as being within Flood Zone 3b will not be permitted.
