Documents 4

Site constraints 4

Local nature reserve 199 m away: Glamorganshire Canal

Work nearby can need a habitats assessment.

Harm to a protected site is only accepted where there is no alternative and an overriding public interest.

Radon affected area, class 5

An estimated 10 to 30% 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.

UKHSA radon ↗

Registered park or garden 99 m away: Whitchurch Hospital

Its setting is a consideration for work nearby.

Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.

Also on the record

SSSI 460 m away: Glamorgan Canal / Long Wood.

Not affected

Outside flood zones 2 and 3 · No listed building at the site · No scheduled monument at the site
