Documents 13

Site constraints 7

Nutrient neutrality catchment: River Dee

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.

Special area of conservation about 103 m away: Johnstown Newt Sites

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.

SSSI about 103 m away: Stryt Las a'r Hafod

Natural England may need consulting, depending on what is proposed.

Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.

Also on the record

National infrastructure project about 1514 m away: Wrexham Energy Centre; 1 listed building within 150 m of the postcode pin; Coalfield, development low risk area.

Not affected

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

Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
