The illustrative masterplan has been arranged to locate all built development within Flood Zone 1, meaning it is at the lowest risk from flooding and is appropriate for housing development. A small watercourse is present in the north of the site, but the proposed development will be located well outside of its associated floodplain.
Environment Agency flood mapping indicates the potential for surface water ponding to occur at several isolated points across the site. These areas are however associated with existing field drainage and local topographical low points in which runoff from within the site can pond. Any existing flood risk within the site will be resolved through the provision of a formalised surface water drainage strategy, which will intercept rainwater falling on the development and store it with designated attenuation basins before it is discharged from the site.
The additional surface water runoff generated by the development will be managed through the implementation of a sustainable drainage strategy. This will ensure that surface water discharge rates do not exceed existing levels and, where possible, will provide betterment over the existing runoff from the site. With appropriate planting, the proposed attenuation areas will also deliver amenity and biodiversity benefits through the provision of new habitats.
Foul water will be directed to the local public sewers. Taylor Wimpey will work with Severn Trent Water (the operator) to ensure that any necessary upgrades to the local sewer network are delivered.
A Sustainable Drainage System (SuDS) for the site will ensure that surface water discharge rates do not exceed existing levels, while providing new wetland habitat to enhance biodiversity.
