Site constraints 5

Nutrient neutrality catchment: River Camel SAC

New homes and overnight accommodation must show nutrient neutrality before approval.

Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.

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.

Also on the record

4 listed buildings within 150 m; Inside the St Mabyn built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 2, but it predates the buildings here and the current map does not class it as farmland.

Not affected

Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site
