High chance: a 1 in 100 or greater annual chance from rivers, or 1 in 200 from the sea. Any development here needs a flood risk assessment. Defences are not counted.

The Environment Agency flood map for planning. Homes in zone 3 must also pass the sequential test. Surface water flooding is a separate map.

South Downs National Park

The park authority decides applications here. Great weight to conserving the landscape; major development restricted.

Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.

Special area of conservation 181 m away: Lewes Downs

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.

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.

SSSI 181 m away: Lewes Downs 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.
