Main issues, as the Inspector framed them
- the effect of the development on the character and appearance of the area
- the highway network, with particular regard to highway safety and the free flow of traffic for all users
- flood risk
What decided it
The demonstrable harm to character and appearance of the area combined with the potential to unduly impede the free flow of traffic, particularly for horse riders on the byway, meant the proposal conflicted with the development plan with no material considerations to outweigh this.
