Tree>#18 is situated at its original location (i.e. retained in place and not transplanted), '
along the north edge of the park currently being constt-ucted. Tree #129 was relocated
from a center median alon the revious Finch Road. ',
g P
Tree #18 has a tnulk diameter of 21 inches, and#129 has one of 23.4 inches (measured 54
inches above grade). In 2008, I measured both trunks to have diameters of 17 inches,
which advises the two trees were growing since that time and the time before or around �!,
their demise (my 2008 report contains the latest historical records for these two trees). I
The conditions of both trees in 2008 are documented to be healthy and v'igorous for #18,
and only fair and marginal for#129. Observations of these trees beyond 2008 and up until
- construction reveals a notable decline in#18, to around marginal, and only a slight change
!" to#129; these changes were a direct result of no water being provided for many years.
Observations of the ground surrounding #18's trunk reveal the following: fill within the
dripline, approximately six feet from the trunk; soil distt.irbance only a few feet from the
, - trunk; drip hoses within 12 to 24 inches from the trunk, watering only 10- to 20-percent of
the tree's total root zone; very dry soil; an absence of mulch; no protection zone being
maintained (or fencing present); and a storm drain riser near northeast edge of canopy.
Obsezvations of the ground surrounding #29's trunk reveal the following: drip hoses cover
much of the rootball (created when relocated),but not its anticipated entirety; soil moisture
inconsistent throughout the drip hose areas; dry soil, particularly for a relocated and
tu�established tree; an absence of mulch; no protection zone being maintained (or fencing
present); and a light pole footing five feet from the ti-unk, at or slightly within the
anticipated rootbalL

Observations of trees adjacent to #18 and 129 reveal unfavorable ground and watering I�
conditions, factors which may also result in further decline and/or demise of those trees. !,
For instance, tree#19 has fill within 18 inches from its trunk, and soil conditions were dry. ��
The two redwoods flanking #129, namely #22 and 128, also have sporadically dry soil I
conditions. i
��6�c�������5 ��� ��c��G�U�(EO��A`����� ''
Based on my observations, the dominant factor contributing towards the trees' demise is a ,
lack of supplemental water to the root zones, both before and during site development.
Additional likely contributing factors for #18 include grading and soil disturbance within ,
its root zone. For#29, the severe impacts inherent with tree relocation also contributes to
its demise, and installing the lighting pole footing may have sliced into the rootball.
For trees being retained, either in place or having been relocated, I recommend the
watering program, both the supply and monitoring of, is intensified immediately. To
achieve this, the drip hoses should be substituted with bubbler emitters, four per tree (i.e.
one per each side) placed mid-canopy for redwoods retained in place, and three feet from
tninks of relocated redwoods. The purpose of the bubblers is to allow soaking of the entire
ground beneath canopies, or for relocated redwoods, their rootballs and several feet
beyond. The moisture depth should reach around 18 to 24 inches per interval; 12-inch tall
benns� can be formed around the perimeters to contain the water. For relocated trees,
watering should occur at least once per week, and for ones retained in place, once every
week or two during the summer months; please ilote the watering cycles and amounts
should be monitored, and adjusted accordingly, by a tree service or landscape maintenance
company.

A three- to four-inch layer of wood chip mulch should also be spread over the ground
beneath the canopies. For trees retained around the park, all soil fill should be manually
dug to be beyond the outermost canopy areas, and fencing established to restrict access
from equipment(can be four-foot tall orange plastic mounted on steel stakes).
For replacement trees, provide continual and active irrigation, and regularly monitor to
ensure function. Upon arrival, they should be free from defects, including damage to the
tri.inks and limbs, as well as having a favorable lateral rooting structure absent of girdling
roots. �
