Main issues, as the Inspector framed them
- whether the development fails to preserve the character or appearance of the Grove Park Conservation Area and its effect on a non-designated heritage asset
- whether it would give rise to unacceptable risk from flooding
- the effect on ecology and biodiversity
- if any harm would be caused by any of the above leading to development plan conflict, whether it is outweighed by public benefits or other considerations
What decided it
The less than substantial harm to the significance of the Grove Park Conservation Area was found, of itself, sufficient to justify dismissing the appeal.
the benefits of housing delivery, biodiversity improvements and other considerations were clearly and demonstrably outweighed by the harm to heritage assets and the flood risk conflict, so the appeal did not accord with the development plan and was dismissed
