Page 5 <br /> July 24, 1996 <br /> Reference: Tree Assessment <br /> Location: West Broadway /Lincoln Street <br /> Subject: Construction Trauma <br /> The drilling showed excellent structure and no discoloring of <br /> wood. The trunks and limbs are very sound and though it has <br /> suffered some improper pruning, the wounds have or are sealing <br /> very nicely. The tree suffered little or no damage from past <br /> winter storms. The leaf is of good size, there is no signs of <br /> discoloration or die back. <br /> The root system on Black- walnut trees are much larger and go <br /> deeper than the Oregon Big Leaf -maple trees and therefore are <br /> much stronger and more efficient and they do very well while <br /> under construction providing they are under the supervision <br /> of a consulting arborist. <br /> I believe every effort should be taken to preserve this tree <br /> during the forthcoming construction. <br /> If I can be of further assistance in this matter or if more <br /> in -depth investigation is needed please call me. <br /> Sincerely, <br /> David Halstead B.S.
