Site constraints 9

In flood zones plus climate change
Inside the extent flood zones 2 and 3 could reach with climate change: the Central allowance for the 2080s on rivers, the Upper End allowance for sea level rise to 2125. From the sea. Defences are not counted.
The Environment Agency flood map for planning. Councils use it to decide when a flood risk assessment and the sequential test are needed. It is indicative and does not show whether a particular property will flood.
Flood map ↗
Special protection area 117 m away: Ribble & Alt Estuaries
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.
Tarleton to Pier Head Liverpool 15 m away
Matters where it crosses or adjoins the site; the route and its margin are protected.
Habitat network: Coastal sand dunes
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
SSSI 117 m away: Sefton Coast 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
Inside the Crosby (Sefton) built-up area; Priority habitat 15 m away: Coastal sand dunes; National infrastructure project 1447 m away: East Irish Sea Transmission Project, at pre-application; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 5, but it predates the buildings here and the current map does not class it as farmland.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 15 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.
