Here’s an Environmental Impact Assessment (not sure for whose benefit, everyone’s presumably.)  It has “been carried out in accordance with the English Heritage Guidance Document  – The Setting of Heritage Assets” but it has used a particular scoring system to assess “kinetic” views.

Slight beneficial 1
Neutral 6
Slight adverse 2
