Site constraints 2

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 ↗
Agricultural land, grade 3a
Best and most versatile land (grades 1, 2 and 3a). Source: the Predictive Agricultural Land Classification Map (Defra and Natural England, 2025; the Welsh Government's Predictive ALC Map 2 in Wales), a model rather than a site survey. Natural England's Provisional ALC map (1:250,000, 1970s), which most planning maps still show, had this area as grade 2. The predicted grade is Defra's current estimate; only a site survey settles it.
Where development of farmland is needed, policy prefers poorer land over the best and most versatile (grades 1, 2 and 3a). Three sources: Natural England's post-1988 field surveys, which are definitive where they exist; the Defra predictive map for England (2025) and the Welsh Government predictive map, modelled from the soil map with 3a and 3b split; and the 1970s provisional map, which planners and other services still show, coarser and with grade 3 undivided. Where the provisional and predicted grades disagree, treat the predicted grade as the current estimate and expect an application to carry its own survey.
Not affected
Not green belt · No listed building at the site · 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.
