DC/26/144206 - Trees in Conservation Areas Approved

Proposal

T1 - Acer negundo (o/s 74) - reduce laterals and crown lift 14m in height. No reduction to height. Reduce laterals by 2m from 8m to 6m on all compass points. A mature Acer negundo standing close to the front of the property opposite no. 74. The tree has extensive lateral limb overhanging the property and the highway. Lateral reduction will reduce end-weight on the longer limbs, improving the structural balance of the crown, and crown lifting will give clearance above the path/parking area and provide better light to the building below. T2 - Acer negundo (o/s 66)) - crown thin and remove dead limbs 9m in height. Crown thin by 20 %. A second Acer negundo positioned opposite no. 66. There is a quantity of deadwood within the crown and the canopy is dense. A light crown thin and removal of all deadwood >25mm will improve light penetration through the crown, reduce wind sail, and remove the risk of falling deadwood over the path beneath. T3 - Walnut - crown reduce 16m in height. Reduce height by 3m from 16m to 13m. Reduce laterals by 2m from 8m to 6m on all compass points. A semi-mature Walnut on the western boundary of the garden. The tree has been previously reduced. Works will retain the established reduction points to maintain the existing crown shape and form, keeping the tree in proportion to its position and reducing end-weight on regrowth from previous cuts. T5 - Rowan ? Remove dead limbs 9m in height. A Rowan situated centrally in the rear garden. The upper portions of the tree show clear dieback. Works are to reduce the crown back to live growth, removing the dead tips and encouraging healthy regrowth from the remaining live framework, prolonging the safe and useful life of the tree.

Council document ↗
Article 4 direction
Small HMO Northern Extension. Named permitted development rights are withdrawn here.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.
Air quality management area: Lewisham 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.
