Dear Mr. Smith:
Pursuant to your request for arboricultural consultation this report concerns a pre-construction review
of several large shade trees indigenous to the site of a commercial property, and, recommendations
pertinent to tree preservation and tree selection.
Site review:
October 29, 1997
Project:
Kwik Kar Lube & Tune
Denton Tap Road South, Coppell, Texas
Scope of construction:
Landscape plan:
addition to building & parking lot; landscape construction
revised 10/30/97 as per Tim Harlow, USA Professional Services Group, Inc.
Tree species:
20" dbh Post Oak (Quercus stellata)
18" dbh Post Oak
10" dbh Post Oak
18" dbh Post Oak
The four (4) Post Oak trees, located west of the existing building and parking lot, are in good
condition and should make the transition following the proposed site work under the following
sequence of guidelines;
1. expose rootflares as per the attached diagram, GRADE CHANGE - REMEDIAL
2. fertilization/soil aeration.., use Doggett XL 12-24-24 with Humates soil injected as per
label instructions
3. install specified screen trees.., adjust planting positions to prevent cutting large Oak
roots.., add one 4" perforated ADS pipe as a vertical pump-out in each pit
4. prevent soil compaction and soil disturbance behind planting line of new trees.., no
equipment access or storage of materials.., install a temporary chainlink fence if needed

5. add fill required to raise grade for parking lot expansion...form and pour concrete...retain-
ing wall
6. irrigation trenches should be hand-dug to prevent damage to large Oak roots.., place
trench and head locations at base of the retaining wall
7. install ornamental trees and shrubs
8. use seed-established turfgrass instead of sod that has a heavy clay.., scalp the area and
remove debris.., use a shallow depth core or slicing aerator as opposed to tilling.., seed
9. irrigation water.., program the controller to keep the seedbed moist but not
waterlogged.., frequent short cycles will accomplish this.., rain stat on the controller
10. curb stops placed so as to prevent damage to Dwarf Yaupon Hollies in planter from
radiator heat and antifreeze
A key element in the protection of root zones of these Post Oaks is to prevent soil compaction and
minimize soil disturbance. The recommended sequence of events will accomplish this goal. Tree
installation equipment such as tractor/loader or winch truck should access from the existing parking
lot and move down slope perpendicular to the planting location.
The site soils appear to be loamy and well drained, however, with the forecast of a wet winter season,
it would be prudent to install an inspection/pump-out pipe in each tree pit to insure that water does
not stand in the pit and compromise tree survival. Inspection should be performed weekly, or, two
days after heavy rainfal[and pumped as needed. The vertical pipe should be placed below the bottom
of the root ball and dayiighted to a height of 4" above the mulch layer, and, not capped.
The rootflares are indicators of the natural grade of a tree. These structures on the Post Oaks have
sustained a raise in soil grade through water movement of soil particles and an accumulation of leaf
litter. Careful exposure of the rootflares, for a radial distance of 12 inches, will create a treewell. The
potential options for retaining the soil walls of the treewells is illustrated in the attached diagram,
GRADE CHANGE- REMEDIAL. Hand trowel is the tool of choice.
The City of Coppell has recommended four tree species suitable as evergreen screen plants. Leylandi
Cypress and the Austrian Pine will struggle in the shade of the Post Oaks. The Southern Waxmyrtle
may become leggy in the shade and attain a 12-15' height. The upright Hollies, such as the Foster
Holly will attain the 20 to 25' height range but do have a narrow profile.
Eastern Redcedar (duniperus virginiana) is a species indigenous to the site and performs very well as
a tall and wide screen plant. Southern Magnolia (Magnolia grandifiora) would be another candidate

for a large evergreen tree. Once established, these species do not required a great deal of water and
are considered to be long term species requiring very little maintenance.
Please do not hesitate to contact me should you have any questions regarding our recommendations
for this project.
