Site constraints 12

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 ↗
Nutrient neutrality catchment: Teesmouth and Cleveland Coast SPA/Ramsar
New homes and overnight accommodation must show nutrient neutrality before approval.
Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.
Cotherstone conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Public footpath 23 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.
SSSI 47 m away: Shipley and Great Woods 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.
Habitat network: Priority Rivers
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
1 listed building within 150 m
Nearest: Summerhouse and Attached Garden Wall, 30 Metres North East of Hagg House, Grade II, 40 m away
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 ↗
Scheduled monument 139 m away: Cotherstone Castle
Its setting is a consideration for work nearby.
Nationally important archaeology protected by the Secretary of State. Work that affects the monument or its setting is rarely permitted.
Historic England ↗
Also on the record
Radon affected area, class 4; Inside the Cotherstone built-up area; Priority habitat 24 m away: Deciduous woodland; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 3, but it predates the buildings here and the current map does not class it as farmland.
Not affected
Not green belt

Checked on 6 October 2026. 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.
