SOUTHLAKE 2035 PLAN: Consolidated Future Land Use Plan
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 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 recommendatio ns that came out of the
adopted FM1938 Corridor Plan for this location.
Pathways Master Plan & Sidewalk Plan
The applicant is proposing to construct a 4’ sidewalk along the east
boundary on Stonebridge Lane.
TRANSPORTATION
ASSESSMENT: Area Road Network and Conditions
The development proposes one access drive connection to an existing
driveway to the south with access onto Stonebridge Lane and a drive
connection to the adjacent drive connection to the east (Jellico Square).
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: It appears that the Tree Preservation Plan complies with the approved
zoning change and concept plan under ZA07 -132. The removal of tree
#114 is proposed to be mitigated by planting four (4) additional canopy
trees on the site.
CITIZEN INPUT: A SPIN meeting was not held for this project.

TREE CONSERVATION COMMENTS:
* It appears that the Tree Preservation Plan complies with the approved zoning change and concept
plan under ZA07-132.
* Except as provided by subsection 7.2.b. of the Tree Preservation Ord inance, 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 Minimum percentage of the
Case No. Attachment C

the entire site 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.
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 th e:
i. 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;
ii. 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 effe cts 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 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 structures,
easements, utilities, structures grading, and any other structure proposed to be constructed do not
conflict with existing trees intended to be preserved.
LANDSCAPE COMMENTS:
* Existing tree credits are proposed to be taken for required interior landscape and east bufferyard
canopy and accent trees. The existing trees proposed to be preserved are located entirely within
the east bufferyard and at least one of them is located outside of the property boundary. Existing
tree credits may only be taken for required East Bufferyard canopy and accent trees and only trees
located on the developing property may be used to provide existing tree credits.

ZA18-0031 Page 3
Interior Landscape Existing Tree Credits: Existing trees which are saved in landscape areas and
have at least 75% of the ‘Critical Root Zone’ within that area shall be granted credits toward
reducing the required plantings.
Bufferyard Existing Plant Credits: Existing trees which are within fifty feet of the property line and
have a minimum of fifty percent (50%) of the drip line within the bufferyard area shall be granted
credits toward reducing the required plantings as set forth in the Landscape Or dinance.
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.
