Knapp&Associates, LLC Consultants in Arboriculture,Silviculture,and Forest Ecology 1132 August 2, 2011 To: Steve Brown, Timberland Homes Subject: Tree Protection—House Demo, Troy Park Today I visited the Troy Park site at 12300 SW Bull Mtn. Road in Tigard. As you requested, I evaluated the need for tree protection in conjunction with demolition of the house located on the property. Three trees could be affected by house demolition: a large cottonwood/poplar(tree 1984), located at the corner of the driveway, and two unnumbered Douglas-firs about 12 inches in diameter growing at the corner of the house. All of these trees can be easily protected during demolition. I recommend the following: • Install protection fence at the edge of the driveway adjacent to the cottonwood and on the house side of the tree. • Install protection fence halfway between the two Douglas-firs and the corner of the house. • Confine demolition activities to the footprint of the house(i.e., demo from the inside out)and the existing driveway and paved areas. This should provide adequate room to complete the job and protect the trees. Please let me know if you have any questions regarding these recommendations, or if I can be of further help during the project. Thank you, PIA Walter H.
