The Site at Orchard Farm lies wholly within Flood Zone 1, outside the maximum flood extents identified on the publicly available Flood Map for Planning associated with the River Avon which runs south of the Site. Surface water flow routes are also identified on the publicly available Long-Term Flood Risk Mapping throughout the Site, which are proposed to be suitably managed in blue-green corridors.
A holistic approach to surface water management will be taken, where development proposals will implement the use of Sustainable Drainage Systems (SuDS) to sustainably manage surface water runoff from, and within, the proposed development. Above ground, tiered SuDS will enhance water quality before discharging into the existing on-Site watercourse or the surrounding Severn Trent Water surface water sewer network (depending on topography of the development parcel) at site-specific runoff rates for all events up to, and including, the 1 in 100 year plus climate change (40%) event.
The proposed approach to surface water management aims to provide amenity and biodiversity value to the wider development, providing an opportunity to enhance the quality of open space provided to residents alongside the primary function of water control which will provide resilience to future climate change.
This will all be reviewed in detail as part of a Flood Risk Assessment and Drainage Strategy which will be submitted to support the proposed planning application
