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 ↗
Public footpath 18 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: Wood pasture and parkland
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
2 listed buildings within 150 m
Nearest: Gardener's Cottage at Ashfold School, Grade II, 42 m away · 2 Grade II
The site itself is not listed. Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.

Historic England ↗
Also on the record
Inside the Dorton built-up area; Tree preservation order 25 m away; Priority habitat 25 m away: Deciduous woodland; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 4, but it predates the buildings here and the current map does not class it as farmland.
Not affected
Not green belt · No scheduled monument at the site

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England 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.
