Main issues, as the Inspector framed them
- the effect on Green Belt openness and purposes
- the effect on the character and appearance of the area, including landscape and visual effects
- the impact on the designated heritage assets at Mopes Farm, with particular reference to the effect on their setting
- the effect on the BMV agricultural land
- the effect on veteran trees, ancient woodland, and biodiversity more generally
- the effect on aviation safety
- whether the harm to the Green Belt and any other harm is clearly outweighed by other considerations, so as to constitute very special circumstances
What decided it
The existence of a less harmful alternative site (CVMSA/Iver Heath) capable of meeting the same identified need moderated the weight given to the appeal proposal's benefits, so that they did not clearly outweigh the substantial Green Belt and other harm to constitute very special circumstances.
The substantial harm to the Green Belt plus significant landscape harm, moderate BMV harm and limited veteran tree/aviation harm was not clearly outweighed by the substantial need and other benefits of the scheme, particularly given a less harmful feasible alternative site existed; the balance tipped against the appeal.
