Main issues, as the Inspector framed them
- the effect of the proposal on the protected species of slow worms
What decided it
The failure to demonstrate that the proposal would not have a harmful impact on slow worms, a protected species, which carries significant weight against the appeal and significantly and demonstrably outweighs the moderate benefits of the proposal.
The moderate benefits of housing supply and mix are significantly and demonstrably outweighed by the significant harm to protected species (slow worms) when assessed against the policies of the Framework taken as a whole under the tilted balance.
What the Inspector cited
- Development plan policies
- Policy 70Policy 72
- National Planning Policy Framework
- Paragraph 11
