26/1548/TPO - Tree Preservation Order Works (8 Week) Awaiting decision
Trees & landscaping

Proposal

A1: x3 large ash tree in the grounds of the church yard, the three trees are at the rear gardens of 85 and 89 Blanche lane. The trees are approximately 70 ft high, there is no plan to reduce the height of the trees they would like the lateral overhanging branches reduced by approximetley 2-3 meters in length cut back to suitable growth points, still leaving a good 2-3 meters of the lateral branches in place. Due to the trees location within the churchyard it would be far easier to view them from numbers 89 and 85 Blanche Lane because of the dense undergrowth (number 85 has a side access to the left of the property for access) Data via plota.co.uk

Site constraints 9

Grade I listed: Church of St Giles
List entry 1174342 · 2 m away · 5 more listed buildings within 150 m (5 Grade II)
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 ↗
Green belt: London
Inappropriate development needs very special circumstances.
Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.

South Mimms 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.
Council document ↗
Public footpath 13 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: Other Priority Habitats -NEX
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Radon affected area, class 3; Inside the South Mimms built-up area; Priority habitat 9 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
Outside flood zones 2 and 3 · No scheduled monument at the site
