  See attached PDF showing satellite view of houses number 20 to 30 on Onslow Avenue. The sycamore tree in the rear garden of number 26 is marked by a red dotted circle on the plan. It is proposed to reduce the height and spread of the tree to growth points approximately 2m above previous pruning. This is to maintain a manageable overall height of 4.5m and spread of 4m of the tree to avoid overhang to neighbouring properties and reduce any potential risk of root ingress into drains.

  The details of the tree marked as Cherry Tree No. 1 on the plans which we are planning on removing are the following: - Type - the tree is an established white flowering cherry tree. - Size the main trunk of the tree is approximately 40cm across with the top branches reaching to a height of about 20ft with a span of 12 ft. - Location - the tree is located 12ft from the front door of the property to the left had side as you look from the road, it is1ft from the party wall with the neighbouring property No. 53, Mt Ararat Road. The reason for removal of the tree is: - There is a pre-existing cherry tree, Cherry Tree No. 2 on the plans, that Cherry Tree No. 1 is competing with and they are in close proximity. - Cherry Tree No. 1 is too close to the house and as it has grown in size the root system represents a potential danger to the property foundations. When removing some plants, a root of approximately 10-15cm in diameter was found 4ft from the front door of the property that extends toward the house itself.
