Site constraints 4

Nutrient neutrality catchment: Yare Broads and Marshes
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.
Conservation area 13 m away: Sewell
The edge of the area; work outside it can still affect its setting.
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
SSSI 270 m away: Catton Grove Chalk Pit SSSI; Inside the Norwich built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 2 November 2026. Historic England, the Environment Agency, Natural England 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.
