Site constraints 4
Nutrient neutrality catchment: Teesmouth and Cleveland Coast SPA/Ramsar
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.
Also on the record
Radon affected area, class 2; Inside the Heighington 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.

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