Site constraints 9

Local nature reserve about 27 m away: Seven Sisters
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.
SSSI about 32 m away: Seaford to Beachy Head SSSI
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Radon affected area, class 6
An estimated 30% or more of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.
From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.
UKHSA radon ↗
National park about 24 m away: South Downs
Outside the park; its setting can still be raised.
Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.
Also on the record
Nature recovery project: Seaford to Eastbourne: Drink-in the Downs; Inside the Seaford built-up area; Heritage coast about 34 m away: Sussex; Priority habitat about 31 m away: Lowland calcareous grassland.
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site
