The site is located within Flood Zone 1 of the Environment Agency’s Flood Map for Planning, which means it has the lowest probability of flooding. There are however small, localised spots of surface water flood risk within the site.
A sustainable drainage system (SuDS) will attenuate surface water runoff from the new neighbourhood. This will include attenuation ponds which are designed to hold surface water run-off from the development within the site, and discharge it at greenfield rates. This means that the amount of water run-off from the site would be no more than the current rates as an undeveloped field and has the potential to be improved. This will ensure that flood risk is not increased elsewhere as part of the proposed development.
The proposed attenuation ponds will also deliver biodiversity benefits through the provision of additional wetland habitat within the site, along with appropriate planting.
A Flood Risk Assessment and Sustainable Drainage Strategy is being prepared as part of the planning application, in accordance with national and local planning policy.
