Page 3 <br /> July 24, 1996 <br /> Reference: Tree Assessment <br /> Location: West Broadway /Lincoln Street <br /> Subject: Construction Trauma <br /> The tree is also showing signs of stress in the upper canopy. <br /> there are areas of twig, and limb die back, premature yellowing <br /> of leaf and the leaf size is very small. Native trees such as <br /> these have a tendency to break down and deteriorate once they <br /> reach a certain maturity. <br /> Though this trees has grown remarkably well within a confined <br /> space and has been subjected to both manmade and natural damage, <br /> I believe that the tree will continue to deteriorate and will <br /> not survive more than another 10 years. <br /> The tree is now 4 feet east of the West Broadway curb and 0 <br /> feet west of the sidewalk. If the forthcoming construction <br /> disturbs the tree's environment by removing the side walk, curb <br /> parking lot asphalt and /or any excavation or disturbance of <br /> the root zone of this trees the trees will go into severe stress <br /> and may die within 5 years. <br /> TREE NUMBER TWO: <br /> Oregon Big Leaf —maple <br /> The tree is located 45.6 feet south of the alley, running west <br /> to east off of Lincoln Street and 18 inches east of Lincoln <br /> Street. It is growing in a parking strip 9.6 inches wide and <br /> 78 feet long. <br /> The DBH is 35 inches and the DGL is 50 inches. The highest point <br /> is 78 feet and the diameter limb spread is 64 feet. The base <br /> of the tree is located 18 inches east of the Lincoln Street <br /> curb and 24 inches west of the sidewalk. Estimated age of the <br /> tree is 80 years. <br />
