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.
Heritage coast: Suffolk
A defined stretch of undeveloped coastline.
Development inconsistent with keeping the coast undeveloped is resisted.
National infrastructure project 92 m away: The Sizewell C Project
The site is 92 m from the project boundary. Generating station, decided. The project page says whether consent was granted. Also within 2 km: Galloper Offshore Wind Farm (decided, 419 m); East Anglia ONE North Offshore Windfarm (decided, 852 m); East Anglia TWO Offshore Windfarm (decided, 852 m); Suffolk Water Recycling Transfer and Storage (at pre-application, 1187 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 ↗
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Special area of conservation 262 m away: Outer Thames Estuary
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.
Also on the record
SSSI 324 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 7 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.
