Site constraints 7

Suffolk Coast & Heaths National Landscape

Great weight to conserving the landscape; major development restricted.

Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.

National infrastructure project: The Sizewell C Project

The site is inside the project boundary. Generating station, decided. The project page says whether consent was granted. Also within 2 km: Galloper Offshore Wind Farm (decided, 824 m); East Anglia ONE North Offshore Windfarm (decided, 1332 m); East Anglia TWO Offshore Windfarm (decided, 1332 m); Suffolk Water Recycling Transfer and Storage (at pre-application, 655 m).

Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Planning Inspectorate project page ↗

Heritage coast: Suffolk

A defined stretch of undeveloped coastline.

Development inconsistent with keeping the coast undeveloped is resisted.

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

Special area of conservation 325 m away: Outer Thames Estuary; SSSI 315 m away: Sizewell Marshes SSSI; Inside the Sizewell built-up area.

Not affected

Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England, the Planning Inspectorate 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.
