28 MANAGING FLOOD RISK THROUGH DEVELOPMENT
The Council will take a risk-based approach to development and flood risk, directing development to areas of lowest risk in accordance with Planning Policy Statement 25: Development and Flood Risk. However:
- Development of sites in the Central Leeside and North East Enfield Area Action Plan areas that lie within flood zones 2 and 3a, but that contribute to the strategic objectives for change in the Upper Lee Valley, will be supported in principle. These schemes will be expected to comprehensively address flood risk, mitigating the impacts of the development and reducing flood risk overall; and
- Redevelopment and intensification of existing industrial sites within the strategic industrial locations will be encouraged, provided that this reduces flood risk overall.
The Sequential Approach, Exception Test, and all other requirements of PPS25 will still need to be applied to individual developments.
Given that there is likely to be redevelopment within the floodplain, there will be increased emphasis on innovative, flood resistant and resilient design, including a requirement to normally set back development from the watercourse. Sustainable Drainage Systems (SUDS) will be required in all developments, irrespective of the flood risk at individual development sites.
Developments proposed in areas identified as being at risk from surface or groundwater flooding (in level 1 and/or 2 Strategic Flood Risk Assessments and in any subsequent surface water management plans) will be required to demonstrate that further investigation of the extent of risk, and the feasibility of options for prevention or mitigation, have been considered.
