Site constraints 5
Coal mining development high risk area
Recorded coal mining features at or near the surface. Most planning applications here need a coal mining risk assessment.
From the Mining Remediation Authority, formerly the Coal Authority. The development high risk area marks recorded coal mining features at or near the surface: mine shafts and adits, shallow workings, mine gas and former opencast sites. Most planning applications there need a coal mining risk assessment; householder applications, changes of use and some minor works are exempt. Mine entry positions come from old plans and can be out by several metres, and unrecorded workings can exist anywhere in the coalfield.
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
National infrastructure project 226 m away: Chesterfield to Willington, at pre-application; Inside the Alfreton built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 4, but it predates the buildings here and the current map does not class it as farmland.
