CUSTOMER: CRAIG PILAWSKI 2010 ABERDEEN PL SE, RENTON
This report is a summary of findings from the tree risk assessments performed on 6 Douglas firs
for the customer and address listed above. 5 of the 6 trees had significant structural defects resulting
from being previously topped decades ago. The resulting regrowth with weak structural attachments
and codominant stems has a higher potential for failure. The overall tree risk rating for the 5 larger
trees (trees 2-6 indicated on site map) is high, with multiple houses and people in backyards as
potential target. Tree #1 (listed on site map) is significantly smaller than the rest of the trees and is
being shaded out in the understory of the larger fir trees. It has little trunk taper and a low live crown
ratio due to being completely shaded. This tree has an overall tree risk rating of moderate and is
unlikely to survive long term in its current condition.
Due to the structural defects and hazards posed by these trees, removal is warranted. Since the
removal of these trees would leave no significant trees on site, the replanting of 4 vine maples is
proposed (as indicated on proposed replanting site map). The lot size is 7000 square feet and the
replanting of 4 vine maples will meet the requirement of 2 significant trees per 5000 square feet. Trees
# 7 and 8 indicated on site map fall within the allotted 2 significant tree removals allowed in any one
year period and were not considered in the tree risk assessments.
