Site constraints 10

Tamar Valley National Landscape

Great weight to conserving the landscape; major development restricted.

Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.

World heritage site: Cornwall and West Devon Mining Landscape

Nationally designated heritage. Its significance and setting carry great weight.

Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.

Historic England ↗

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 rivers and 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 area of conservation about 225 m away: Plymouth Sound & 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.

Habitat network: Network Enhancement Zone 1

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

Radon affected area, class 6

An estimated 30% or more of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.

From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.

UKHSA radon ↗

Also on the record

SSSI about 225 m away: Tamar - Tavy Estuary SSSI; Flood defence about 25 m from the postcode pin (engineered high ground); Inside the Calstock built-up area; 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

Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area. Historic England, the Environment Agency, Natural England, the British Geological Survey and UK Health Security Agency (radon, contains BGS materials © UKRI) 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.
