RE:
Kwik Kar Lube and Tune Center Addition ] Coppell, Texas
USA Project No. 97076
Dear Sid,
The landscape plan for the above referenced project has been revised to reflect the existing trees. We have
visited the site (the morning of August 6, 1997) and found that all the existing trees (Post Oaks) are in
seemingly good health. We also found a number of smaller, understory trees, somewhat diverse in specie
and size, that should not effect your construction, but would be a valuable asset to the City and their
proposed trail system traversing the west end of this site. Please make every effort to preserve these trees if
possible. We have also noted that 2 existing trees shown on the plans you provided us, no longer exist. We
trust that Kwik Industries adequately addressed the mitigation of these trees during the initial construction of
the existing Lube and Tune Center. Therefore, we have taken them completely off our landscape plan to
prevent City Staff confusion and minimize possible questions and delays.
For your information, and to assist you in your City presentation, the following conditions and considerations
apply:
We have taken 2 proposed parking spaces away to protect 2 existing Post Oak trees (one 18" caliper
and one 14" caliper tree). These trees are located outside the building envelope, therefore their
removal would require tree mitigation and a permit. Current Coppell ordinance would require Kwik
Industries to mitigate the loss of these 2 trees, and replacement would be an inch-for-inch requirement.
The combined caliper inch of these 2 trees equals 34 caliper inches. Replacement trees would need to
be a minimum of 3' caliper, thus requiring 12 trees to be planted in mitigation, on the site. Kwik
Industries would be hard pressed to plant that many trees on this site, noting the dense, existing stand
of bees to the west of the proposed improvements and the fact that concrete drives are proposed to the
property lines to the north and south - you simply do not have enough room with the proposed
improvements you are wanting to construct.
2. By protecting these two existing trees referenced above, the City may be more willing to grant a parking
space variance, if that is a necessary issue.

By creating an island for the preservation of the above referenced trees, Kwik Industries may need to
construct a retaining wall/tree well. Looking at the existing and proposed grades furnished to us, we feel
that a wall (or curb turndown) approximately 2' in height will be necessary along the back of curb to
protect these trees. A closer examination by your civil engineer of the proposed parking lot grades and
finish grade elevation of the trees will determine the true height of this wall. If a wall higher than 2' is
required, City ordinance will require Kwik to install a hand rail to protect patrons from the vertical
elevation change. Kwik may want to consider this regardless of the height of the wall, for patron safety
and reduced liability of Kwik Industries and the franchise owner. If a wall is required, please insure
adequate surface drainage away from the base of these trees. Also, minimize any grading activities in
this island because of the sensitive nature of Post Oak trees to construction, fill, and grading activities.
Since the tree locations are outside the building envelope, the City may very welt make you mitigate
these trees if they die within a year or two, due to construction activities.
Tree wells may be necessary for the two existing Post Oak trees (one 10" caliper and one 14" caliper
tree) directly west of the proposed Lube Center addition, to protect these trees. Again, a closer
examination by your civil engineer of the proposed parking lot grades, the Slope of proposed grade to
existing grade, and finish grade elevation of the. trees will determine the true height of this wall. If
required, please insure adequate surface drainage away/around the base of these trees. Also,
minimize any grading activities under the exislJng canopy of the trees, because of the sensitive nature of
Post Oak trees to construction, fill, and grading activities. Please note however, since the tree locations
are inside the allowable building envelope, the City may not require mitigation of these trees if they die
within a year or two, due to construction activities.
The existing sanitary sewer installation may eventually effect the health and vigor of a number of
existing trees to the west of the proposed site improvements. We mention this for the record, that
should these existing trees die along the sewer easement, it would most likely be a cause of the sewer
installation and not that of the proposed site improvements Kwik Industries has shown on the
information you provided to us.
Should you have any further questions or comments, please feel free to contact me at your convenience.
We hope this revised landscape plan will provide you with the tool necessary to obtain City approval and
allow you to begin construction on the proposed addition to the Coppell Kwik Kar Lube and Tune Center.
Sincerely, . /
