Site constraints 14

Metropolitan Open Land
Green belt level protection inside London.
The London Plan gives Metropolitan Open Land the same protection as green belt: inappropriate development needs very special circumstances.
Registered park or garden: Grovelands Park
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 ↗
Article 4 direction
Borough wide. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
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. 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 ↗
Heritage at risk: Grovelands Park
On the register of historic places assessed as at risk.
A designated building, monument, park or conservation area assessed as at risk from neglect, decay or development. Proposals that secure its future are looked on favourably.
Historic England ↗
Archaeological priority area
An assessment or field evaluation may be asked for before ground works.
The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.
Air quality management area: Enfield AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
Council record ↗
Habitat network: Wood pasture and parkland
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
3 listed buildings within 150 m; Conservation area 58 m away: Winchmore Hill Green; Priority habitat 7 m away: Deciduous woodland; Inside the Enfield built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square; Designated open space 39 m away.
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site
