Main issues, as the Inspector framed them

  • whether the site is a suitable location for the proposal having regard to the spatial strategy for the district
  • the effect of the proposal on the integrity of the Arun Valley Special Protection Area, Special Area of Conservation and Ramsar site, with particular regard to water neutrality

What decided it

The Council's inability to demonstrate a five-year housing land supply, combined with the proposal's compliance with water neutrality requirements and the modest but meaningful contribution to housing delivery, outweighed the locational conflict with the development plan.

the adverse impacts of granting permission, comprising conflict with the spatial strategy and locational unsuitability, would not significantly and demonstrably outweigh the benefits of contributing to housing supply and making efficient use of land when assessed against the Framework as a whole, in the context of a significant shortfall in housing land supply
