Main issues, as the Inspector framed them
- whether the site is an appropriate location for two new build dwellings taking into account spatial strategy planning policy
- whether it has been demonstrated that the proposed development would have no adverse effect on protected species and habitats and would contribute to measurable Biodiversity Net Gain
What decided it
The failure to demonstrate that the development would not adversely affect the integrity of the Arun Valley Sites through water abstraction, which under Regulation 63 of the Habitats Regulations prevented the Inspector from granting permission.
The substantial benefits of housing delivery and efficient use of previously developed land were outweighed by very great weight attached to the harms to protected habitats and the conflict with spatial strategy, with the presumption in favour of development displaced by the protected habitat impacts.
