Scoping Opinion request relating to this development
On 22 May 2023 the Oxford Health NHS Foundation Trust submitted the following Scoping Opinion request to Oxford City Council planners relating to this proposed development:
The planners decided on 2 October 2023 that the Warneford plans constituted EIA (Environmental Impact Assessment) Development and that an Environmental Statement would be required, particularly relating to the Lye Valley SSSI: see the twelve-page Decision under the Documents tab in the above link. The planners state:
Flooding (fluvial, surface water and groundwater)
The site is within 750m of the Lye Valley SSSI which is highly sensitive to changes in hydrology and groundwater, containing rare peats deposits within the City. Due to the size and nature of the development this has a high potential to significantly impact on this sensitive receptor;Impact on water quality and hydrology
As aboveImpact on the Ecology
As above and in addition the potential impact on identified Protected Species within the site.

Local Transport Plan for Headington
The consultation by Oxfordshire County Council on its “Connecting Oxfordshire: Local Transport Plan 2015–2031” closed on 2 April 2015.
This plan included new hospital routes for the “eastern arc” (from Cowley to Headington), and this more detailed drawing showed a road running along Lye Valley road in a northwards direction and then across the Lye Brook. Judy Webb believes that this would be a disaster for wildlife in the Lye Valley.
