Site constraints 6

Habitat network: Network Enhancement Zone 1
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Radon affected area, class 6
An estimated 30% or more of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.
From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.
