The 2035 future land use designation for
the site is Office Commercial which is
defined in the Southlake 2035 plan as
follows:
“The Office Commercial category is a
commercial category designed and
intended for the exclusive use of office and
limited office-related activities. It is
established for and will be allocated to
those districts best suited for supporting commercial activity of an office
character. It has been established to encourage and permit general
professional and business offices of high quality and appearance, in
Case No. Attachment A
ZA17-100 Page 2
attractive landscaped surroundings with the types of uses and design
exterior appearance so controlled as to be generally compatible with
existing and future adjacent and surrounding residential development.
Properties with this designation may serve as a transition between
established residential neighborhoods, major roadways, and retail
development.
There were no specific land use recommendations that came out of the
adopted FM1938 Corridor Plan for this location.
Pathways Master Plan & Sidewalk Plan
The applicant is proposing to construct a 5’ sidewalk along the
southwest boundary on Stonebridge Lane.
TRANSPORTATION
ASSESSMENT: Area Road Network and Conditions
The development proposes two access driveways onto Stonebridge
Lane and a connection to the adjacent property to the east (Jellico
Square).
There is an existing connection to Jellico Square from the lot directly to
the south (Lot 2R2). And, there is an existing median at the exit drive
onto FM 1709 which forces right-out turns only from the development.
Traffic Impact
A Traffic Impact Analysis (TIA) threshold worksheet was submitted and
reviewed by staff. No TIA will be required for this project.
TREE PRESERVATION: The proposed preservation of existing canopy cover complies with the
Existing Tree Cover Preservation Requirements of the Tree
Preservation Ordinance. The existing tree cover is 76% and a minimum
of 40% of the existing tree cover is proposed to be preserved. The
applicant is proposing to preserve 47% of the existing tree cover.
UTILITIES: Water
There are existing 8” and 6” water lines along Stonebridge Lane that will
serve this property.
Sewer
There is an existing 8” sanitary sewer line along the east side of
Stonebridge Lane that will serve this property.

The submitted landscape plan indicates a 5’ Type A in that area. Please provide correction or
add a S-P-2 zoning regulation allowing the 5’ Type A bufferyard as shown.
4. Provide turn radii labels on the site plan. Fire lanes require a minimum 30 foot inside turn radius
and a minimum 54 foot outside turn radius.
5. The site data table lists impervious coverage for Lot 3R1 as 48% on the approved concept plan.
The site data table on the submitted site plan lists impervious coverage at 49%. Please provide

Tree Conservation/Landscape Review
Keith Martin
Landscape Administrator
Phone: (817) 748-8229
E-mail: kmartin@ci.southlake.tx.us
TREE CONSERVATION COMMENT:
1. The color Tree Conservation Plan proposes to mitigate 33” caliper inches of existing tree to be
removed by planting 9 – 4” caliper trees. As long as the proposed tree removal and
preservation complies with the Existing Tree Cover Preservation Requirements outlined within
the Tree Preservation Ordinance, tree removal mitigation would not necessarily be required.
There is no information provided on which trees are specifically being removed and mitigated.
Please clarify.
2. Significant topography grade changes are proposed in the east and south landscape areas
where existing trees are proposed to be preserved. Please ensure that the proposed grading
does not conflict with existing trees proposed to be preserved. A protected tree shall be
considered to be altered if one or more of the following occurs: more than twenty-five percent
(25%) of the critical root zone is adversely affected, more than twenty-five percent (25%) of its
canopy is removed, or the tree is disfigured to the extent a reasonable person would conclude
the tree will not survive.
* The proposed preservation of existing canopy cover complies with the Existing Tree Cover
Preservation Requirements of the Tree Preservation Ordinance. The existing tree cover is
76% and a minimum of 40% of the existing tree cover is proposed to be preserved. The
applicant is proposing to preserve 47% of the existing tree cover.
* 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.
Table 2.0 – Existing Tree Cover Preservation Requirements
Percentage of existing tree cover on the
entire site
Minimum percentage of the existing
tree cover to be preserved*
0% – 20% 70%
20.1 – 40% 60%
40.1% - 60% 50%
60.1% - 80% 40%
80.1% - 100% 30%
*The minimum percentage of existing tree cover to be preserved shall exclude any area in public rights -
of-way as approved by City Council.
* 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 is a violation of the Tree Preservation Ordinance and
the zoning as approved by the Southlake City Council. Please ensure that the layout of all
Case No. Attachment C
ZA17-100 Page 3
structures, easements, utilities, structures grading, and any other structure proposed to be
constructed do not conflict with existing trees intended to be preserved.
INTERIOR LANDSCAPE AND BUFFERYARDS COMMENTS:
1. The color Landscape Plan design does not match the black and white Landscape Plan design.
There is a Red Bud shown on the south east bufferyard that is not shown on the black and
white Landscape Plan.
2. Label and identify all required and provided bufferyards on the Site Plan.
3. Clearly delineate which existing trees are being used to provide existing tree credits for
required interior landscaping and bufferyard landscaping.
4. Existing tree credits are proposed to be taken for existing trees preserved within the interior
landscape and bufferyard areas. Existing tree credits shall only be granted if the tree/s are in
healthy condition and all requirements of the Tree Preservation Ordinance have been met as
determined at the time of inspection for a Permanent Certificate of Occupancy.
