Site constraints 8

Flood zone 3, rivers and sea
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.
Flood map ↗
Special protection area about 47 m away: South West London Waterbodies
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 47 m away: Wraysbury No. 1 Gravel Pit 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.
Also on the record
National infrastructure project about 499 m away: Expansion of Heathrow Airport (Third Runway), at pre-application; Inside the Old Windsor and Wraysbury built-up area; Green belt about 47 m away: London; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 1, but it predates the buildings here and the current map does not class it as farmland.
Not affected
No scheduled monument at the site

Checked on 6 October 2026.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
