Site constraints 10

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 102 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.
Public footpath 25 m away
Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.
Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
SSSI 102 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.
Also on the record
National infrastructure project 1801 m away: M4 Junctions 3 to 12 Smart Motorway; Inside the Old Windsor and Wraysbury built-up area; Green belt 27 m away: London; Flood defence 42 m away (natural high ground, designed for a 1 in 5 year flood); 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 listed building at the site · No scheduled monument 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.
