Dix, Landscape Architect.In evaluating the existing trees, visual assessment of the trees was performed in addition to the existingand proposedsite features that surround the existing trees including soil conditions.Various factors were evaluated at each tree that include the items listed below:1. Overall health and vigor of tree.2. Size of tree, height and canopy crown ratio.3. Density of tree canopy or needles.4. Injury to tree trunk, branching5. Insect or rodent burrowing activity.6. Disease, fungal infections, etc.7. Damage to tree roots8. Condition to root collar.9. Portion of tree that is dead, including branches.The site currently consists of a single family residence with covered parking carport, detached garage,sheds, patios,driveways and substantial garden areas. The garden areas consist of typical ornamental trees (and shrubs) plantedin the Pacific Northwest Region including Fir, Blue Spruce and fruit trees, none which are of significant tree size.The three (3) significant trees that are located on the subject site include the following:a) 28" d.b.h. Pseudotsuga menziesii (Douglas Fir)b) 10" d.b.h. Acer sp. (Maple)c) 8" d.b.h. Cratageus sp. (Hawthorn)Douglas FirMaple treeHawthorn This tree has a estimated height of between 55.0' and 65.0' with a canopy width of 35.0' to 45.0'. The tree trunk isstraight and shows no signs of leaning in any particular direction. No disease, rot or infestation was noted. Nosignificant damage to the trunk was observed with the exception of where tree branches had been cut in prior years creating a scar with some sap seepage. Smaller, dead branches occur within the canopy center plus a dead branch.The soil within the tree Critical Root Zone is compacted with a gravel driveway encroaching approximately 50% of theSouth area of the Critical Tree Zone. Furthermore, existing wood stockpiles are stacked within this zone and large logslaid horizontally in this area to define the gravel driveway. A Dump Truck was parked below the tree at the time of visittime of the site visit (October 5, 2018). The tree is in very good condition, does not pose a hazard except for the treeThis tree is in good condition with a height of 25.0' to 30.0' and a canopy width of 35.0' to 40.0' with an asymmetricalcrown. Since this tree is being removed, it was not observed in detail.This tree has a trunk that is approximately 15" off an adjacent 5.0' high concrete block retaining wall and 6.0' high solid wood fence set on top of the concrete block wall, located on property line. Due to the close proximity of the wall, the tree root structure is most likely compromised at that side of tree. The height of the tree is approximately 20.0' to 25.0' with a canopy width of 15.0' TO 20.0'. Moss is evident at the north and east sides of the trunk with a 6"wide x 18" high clear-through trunk cavity approximately 7.0' above finish grade. Minor bark damage from a unknown source was observed, but in general this tree is in good condition and should be retained.being isolated as a solitary tree and should be retained.NOTES:a)b)ONE (1) NON-SIGNIFICANT BLUE SPRUCE TREE WILL BE RETAINED.c)TWO (2) NON-SIGNIFICANT ORNAMENTAL FIR TREES WILL BE RELOCATED.d)
