We mostly agree with the list of benefits and challenges, but please see our answer to Q3.

We note that the site includes areas of railway land, which is potentially contaminated land. This is a challenge that has not been referenced. It is likely that any planning application would need to be accompanied by a desk top study, site investigation and proposed remediation strategy. As per the hierarchy within paragraph 020 of the Planning Policy Guidance (PPG) for Water supply, wastewater and water quality, we would expect a development of this scale to connect to the mains foul sewerage network. This means demonstrating and providing evidence that capacity is currently available or can be made available in time to serve the development in accordance with PPG. Page 31 of the Sustainability Study acknowledges that “increased growth in the plan area will also likely impact upon the capacity of the Thornham wastewater treatments works that serves it.” The ‘Position Statement on managing new housing development in the Thornham Waste Water Treatment Works catchment’ (available on Chichester District Council’s website) will need to be considered. Development may need to be phased to ensure that any necessary capacity increase at Thornham wastewater treatment works is delivered prior to occupation. Early engagement with Southern Water will be necessary.

No comment as matters of transport impacts are outside of the Environment Agency’s remit.
