Background Information A Plus Tree was asked to evaluate and to assess 5 western redcedar trees
at Valley Springs Apartments, at 15300 Southeast 155th Place, Renton, WA
98058.
Assignment and any
limiting factors
The assignment was to evaluate the health and risk factors of the trees to
be removed, and this assessment was done using a Level 1 – limited
Visual inspection. There was no soil or tree sampling taken for
examinations or any other physical testing.
Discussion All of these trees are healthy, with vigorous foliage and no observable
defects or decay in the roots, trunk, or branches of these trees. However,
they are planted over the top of underground utilities, and any conflict
with these utilities will necessitate the removal of these trees.
In addition, these trees are planted in limited soil space and root intrusion
underneath the nearby sidewalks is likely. Root pruning is not feasible, as
the distance from the trunk to roots needing to be pruned would likely
destabilize the tree and lead to hazardous conditions. Furthermore,
branches will continue to create conflicts with landscaping on the
neighboring property as the mature crown spread of these trees is wider
than the space allotted between the neighboring property and the
building.
Recommendation The most appropriate course of action for these trees would be to remove
them and grind down the stumps and any surface roots as well. One
deciduous tree with a narrower crown and root system less likely to
create conflicts with hardscape will be planted for every tree removed.

Replanting Plan
All trees that will be removed will be replaced at a 1:1 ratio, with one replacement tree for
every tree to be removed. The replacement trees will be replaced around 5 feet away from the
trees to be removed, or in the same location with topsoil filling the hole where the stump would
be. The trees will all be 15 to 20-gallon containerized stock, and the species and approximate
size of the trees at caliper can be found in the below table, with location numbers
corresponding to the numbers of the location pins on the replacement site map below the
table:
