Description

T1 Walnut; remove, upon site visit this week () the tree is struggling to create any substantial foliage with retrenchment at that tips and the buds curling, I believe a heavy enough reduction would not conform to British standard and the tree will only decline further. I have advised my client about replanting a similar species in a similar location on site. G1 There is also a yew, a horse chestnut, two sycamores and two conifers that he has requested be crown raised to the fence height, approx 2 meters Data via plota.co.uk

Site constraints 4

Tongdean 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 ↗
Local nature reserve 103 m away: Withdean & Westdene Woods
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.
Radon affected area, class 5
An estimated 10 to 30% 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.
