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.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Inside the Norwich built-up area; Priority habitat 32 m away: Deciduous woodland.
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.
