Nutrient neutrality catchment: River Derwent & Bassenthwaite Lake SAC
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.
Lake District National Park
The park authority decides applications here. Great weight to conserving the landscape; major development restricted.
Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.
World heritage site: The English Lake District
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 ↗
Public footpath 17 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: Network Enhancement Zone 1
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Special area of conservation 304 m away: River Derwent & Bassenthwaite Lake
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.
