TRER16-0128 Tree Conservation Plan and Tree Removal Permit for TD
Ameritrade
TD Ameritrade is requesting approval of a Tree Conservation Plan and Tree
Removal Permit for TD Ameritrade's regional campus on property described as Lot
1 R1 R1, Block 1, Sabre Group Campus Addition, an addition to the City of
Southlake, Tarrant County, Texas and located at 1051 (also addressed as 1801)
W. Kirkwood Blvd., Southlake, Texas. Current Zoning: "NR -PUD" Non -Residential
Planned Unit Development District. SPIN Neighborhood # 1.
REQUEST: The applicant is requesting approval of a Tree Conservation Plan and Permit to
remove additional trees that were not shown on the Tree Conservation Plan
submitted with the approved Site Plan. The changes to the plan are needed to
allow the installation of a temporary construction access road to divert the majority
of traffic off of the southern portion of W. Kirkwood Boulevard, near the Kirkwood
Hollow neighborhood and to address changes needed on the bridge position and
grading required by the Army Corp of Engineers.
The existing tree cover on the site is approximately 65.3% and 40% of that tree
cover is required to be preserved. The current approved Tree Conservation Plan
shows that 76% of the existing tree cover is to be preserved. The revised Tree
Conservation Plan shows an additional 3.73% of existing tree cover to be removed
for the Temporary Access Road, the bridge realignment and revised slope grading
around the bridge and other portions of the permanent access road. Approximately
72.27% of the existing tree cover is proposed to be preserved which meets the
Existing Tree Cover Preservation Requirements of the Tree Preservation
Ordinance. No variances are requested.
ACTION NEEDED: Consider approval

TREE CONSERVATION COMMENTS:
* TD Ameritrade is proposing to realign the site access road off of West Kirkwood Blvd. and
the bridge that crosses the Kirkwood Branch Creek because of unforeseen interference
with the existing topography grade elevations within the flowage easement along the
creek. They are also proposing a Temporary Access Road off of West Kirkwood Blvd. to
ease the construction of the access road and bridge.
The existing tree cover on the site is 65.3% and 40% of that tree cover is required to be
preserved. The current approved Tree Conservation Plan shows that 76% of the existing
tree cover is to be preserved. The revised Tree Conservation Plan shows an additional
3.73% of existing tree cover to be removed for the Temporary Access Road off of West
Kirkwood Blvd., revised access road realignment, and revised slop grading around the
bridge and other portions of the access road. 72.27% of the existing tree cover is
proposed to be preserved which meets the Existing Tree Cover Preservation
Requirements of the Tree Preservation Ordinance.
Except as provided by subsection 7.2.b. of the Tree Preservation Ordinance, a Tree
Conservation Analysis or Tree Conservation Plan shall be approved if it will preserve
existing tree cover in accordance with the percentage requirements established by Table
2.0. If the property has previously received a tree permit related to development, the
percentage of existing tree cover at the time the first such permit was issued shall be
used to calculate the minimum existing tree cover that must be preserved under this
section.

*The minimum percentage of existing tree cover to be preserved shall exclude any area in public rights-
of-way as approved by City Council.
For property sought to be zoned for the Downtown zoning district or a planned
development zoning district, including an S -P-1 Site Plan, S -P-2 Site Plan, Transition,
Rural Conservation, Planned Unit Development, or Employment Center zoning district,
the City Council shall consider the application for a Conservation Analysis or Plan in
conjunction with the corresponding development application (as established in Table 1.0).
The Planning and Zoning Commission shall review the application and make a
recommendation to the City Council regarding the application. The City Council shall
approve the Plan or Analysis if the Council finds that the Plan or Analysis provides for the:
placement of building pads, parking areas, driveways, streets, and utility
easements so as to maximize the preservation of environmental features of the
property including mature tree stands, natural creeks and ponds, and significant
grades;
maximizes the preservation of tree cover preservation areas indicated on the
Environmental Resource Protection Map;
iii. maximizes the preservation of existing tree stands with the potential to buffer
residential areas from the noise, glare, and visual effects of nonresidential uses;
iv. maximizes the preservation of existing trees, if any, adjoining a natural or man-
made drainage creek;
V. maximizes the preservation of existing protected trees along rural roadways and
other streets as identified and prioritized in the Street Typology designation; and
vi. mitigation of altered trees through proposed tree replacement procedures pursuant
to this Ordinance.
Please be aware that all existing trees shown to be preserved on the City Council
approved Tree Conservation Plan must be preserved and protected during all phases and
construction of the development. Alteration or removal of any of the existing trees shown
to be preserved on the approved Tree Conservation Plan without approval of a Tree
Removal Permit is a violation of the Tree Preservation Ordinance. Please ensure that the
layout of all structures, easements, utilities, structures grading, and any other structure
proposed to be constructed do not conflict with existing trees intended to be preserved.
