1. The following issues pertain to the driveways and compliance with the Driveway Ordinance No.
634, as amended:
a. A minimum driveway stacking depth of 75 feet is required, measured from the R.O.W. to
the nearest parking stall or intersecting drive lane pavement edge. The applicant proposes
a depth of approximately 30 feet. Variance Requested
* The existing driveway accessing N. Carroll Avenue is “non -conforming” with the
regulations of the Driveway Ordinance regarding minimum centerline spacing and
stacking requirements. Due to the proposed changes to the site, Section 4 .0 requires
that the driveway be brought into compliance. Neither the existing driveway nor a
reconstructed driveway can to be placed onto Carroll Avenue without approval of a
variance to the spacing requirements. Applicant has proposes removal of the existing
driveway and a new driveway onto Lakewood Drive that is compliant with the spacing
requirements.
2. The parking lot requirement for the medical use is 42 spaces and the parking lot requirement
for the office use is 21 spaces. The total parking requirement is 63 spaces. The proposed
parking is 60 spaces. A variance for the parking spaces will be required. Variance Requested
3. In the Master Pathways Plan, the required 8 ft. sidewalk width along North Carroll Avenue is
proposed as a 5-foot sidewalk along the curb. A variance will need to be requested to reduce the
width of the sidewalk along N. Carroll Avenue. A pedestrian access easeme nt (P.A.E.) will be
required for the areas of the N Carroll Avenue sidewalk that are not within the right -of–way in an
amended plat or by separate easement. Variance Requested
4. The proposed sidewalk is located at the curb along N. Carroll Avenue. In the Subdivision
Ordinance No. 483, as amended, Section5.06, C. Sidewalk Specifications, 1. Sidewalk Size and
Case No. Attachment C
ZA18-0028 Page 2
Locations: Sidewalk Size and Locations: All sidewalks shall be at least four feet wide or in
conformance with the Trail System Master Plan, whichever i s greater, and shall be located
between the curb or grade line of the public street and the ROW line or public access easement if
approved by the city, no closer than two (2) feet to the curb or grade line. The City Engineer or
Building Official may alter alignment so that the sidewalk meanders within the area between the
curb and right-of-way line. In the narrative, please provide a justification for the sidewalk to be
located along the N. Carroll Avenue curb.
A variance must be requested to allow the sid ewalk as shown on the site plan. Variance
Requested

TREE CONSERVATION COMMENTS:
* The proposed tree conservation complies with the Existing Tree Cover Preservation Requirements
of the Tree Preservation Ordinance. There is 14.56% of existing tree cover on the site and 70% of
the tree cover is required to be preserved. The app licant is proposing to preserve 72.62% 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 cov er 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 ca lculate 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 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:
Case No. Attachment C
ZA18-0028 Page 3
1. The interior landscape area seems to be incorrect. Based on 50% of the proposed floor area I
calculated 5,860 square feet instead of 6,098 square f eet.
* The proposed building addition exceeds both 30% of the existing building floor area and 5,000
square feet, so both interior landscape and bufferyards landscaping are required to be provided.
The applicant is providing the required interior landscap ing and bufferyards.
* The full width of the required bufferyards is provided but the canopy trees and accent trees
required within the east bufferyard have been relocated on the site in order to accommodate for
the existing overhead and underground utili ties.
Tree Preservation Ordinance 585-E; Section 12.4
A person commits an offense if the person:
a. plants any required replacement tree within an area such that the mature canopy of the tree
will interfere with existing or proposed overhead utility line s;
b. plants any required replacement tree or street tree within an area such that the mature critical
root zone of the tree will interfere with existing or proposed underground public utility lines
(including water lines, sewer lines, transmission lines or other utilities), or such that the
installation and/or maintenance of such utility lines will, in reasonable probability, require
activity in the mature critical root zone of such tree;
* Existing tree credits for interior landscape a bufferyard ca nopy trees and accent trees are
proposed to be taken. 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.
