Tree Solutions Arborist Report-Vehrs SP.pdfConsulting Arbarists
Project No, TS - 4607
Observations and Discussion
I measured the Shore pine (Pinus contorta) tree to be 25 inches in diameter. The tree appears to hav,-
good vigor but there are also symptoms of stress. I found European shoot moth in several sections of
the canopy and Sequoia pitch moth within the trunk in a few locations.
The drip line of the tree extends 12 feet to the east and 13 feet to the west. There has been some land
clearing to the west, outside of the drip fine, that has exposed a root system within the first few inches
of the soil surface. The area disturbed covers approximately 50 percent of the tree's critical root zone
(CRZ) on the west side. The CRZ is defined as an area equal to one radial foot extending from the tree
for each inch of trunk diameter. This is a more accurate representation of the area where a tree's root
system is located rather than the drip line.
The City is requiring improvements to the right-of-way (ROW) that would extend a sidewalk across the
front of the property to the east of the tree. The back of the sidewalk will be six to seven feet away
from the base of the tree's trunk. To construct the walk will require removal of organics from the top of
the soil surface. Due to the shallow root system it is likely that feeder and absorptive roots will be
negatively impacted. The cleared area will need to be compacted before approximately 24 inches of fill
will be placed over the surface. The fill will need to be graded down at a 1:1 ratio, which would place
the fill up to the base of the tree. An impervious sidewalk will need to be placed over the fill soil.
To safety construct the sidewalk, the entire CRZ and drip line area east of the tree will need to have fill
soil placed over the existing grade. With compaction and the placement of fill, the soil hydrology will be
altered leading to soils that retain moisture. Pine trees do not tolerate soils with high moisture
retention properties. If the requested ROW improvements occur there will be an extensive incursion
into the tree's root system, which will lead to the trees decline. These improvements do not adhere to
the Edmonds City Code Section 18.45.050 (H) for a retained tree.

D M,
In my opinion the proposed ROW improvements will negatively impact over 50 percent of the trees C
and most of the area "Protected' area below the trees drip line, There is a high probability that the tree
will decline and eventually fail.
