The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Also on the record
2 listed buildings within 150 m; Coalfield, development low risk area; Inside the Cornforth built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 3, 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

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England, the Mining Remediation Authority and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
