  BACK GARDEN: T1 Weeping Willow: CROWN REDUCE to previous pruning points. Council Note The validated public description identifies the tree but omits the proposed operation. The submitted notice seeks to reduce the tree back to its previous pruning framework. Previous TCA 24/02822/TCA authorised crown reduction of the same back-garden Willow from approximately 8m to 5m in height and from approximately 6m to 5m radius. The current works are therefore recorded as repeat crown management to previous pruning points.
