  T1 - Mulberry Tree: This tree is growing to the south with the canopy extending over the garden area of 25 The Close by 4.5 m with an overall canopy spread to this aspect of approximately 6.5 m. The tree is causing a nuisance to 25 The Close as it prevents proper use of the garden area. This is through the physical presence of the canopy and dropped fruit which is making a footpath slippery and unsafe to use and staining the footpath surface. To help alleviate the nuisance it is proposed to reduce the canopy by 2.0-2.5 m by undertaking the following tree works to the southern aspect. Remove: - 1 x 25 mm diameter stem - 1 x 30 mm diameter stem - 1 x 40 mm diameter stem - 1 x 50 mm diameter stem - 1 x 175 mm diameter stem. This will leave a canopy spread to the southern aspect of approximately 4.0-4.5 m and 2.0-2.5 m over the garden area of 25 The Close. The footpath would then be outside the canopy spread of the tree. All works would be undertaken to BS 3998:2010 `Tree Work: Recommendations'. The tree would be left with a natural and flowing form.
