First Floor = 4,000
Second Floor = 0
Third Floor = 0
Effective Floor area 4,000
Times 50%
= Required Landscape area
x .50
2,000 sq.ft.
Required Canopy Trees @ 11500 sq. ft. = 4
Required Understory Trees @ 1/250 sq. ft. = 8
Required Shrubs @ 1/40 sq. ft. = 50
Required Ground Color area @ 15% = 300 sq. ft.
Required Seasonal Color @ 2% = 40 sq. ft.
C. Location Requirements: A minimum of 75% of all required interior landscape area
and plant material within the interior landscape areas shall be in the front and along
either side of the building between the building and the interior edge of the required
bufferyards and a portion thereof shall be placed adjacent to the building where
practical.
d. Water Conservation Credits: Where systems in accordance with Section 3.6a herein
are utilized in at least 75% of all shrub beds, the required landscape area may be
reduced by 5 %.
3.4 PARKING LOT LANDSCAPE AREA REQUIREMENTS: The parking lot landscape area
requirements shall be as follows based on the percentage of parking located between the
10
building fagade and the R.O.W.. Any new parking area added to an existing site shall
comply with the requirements herein.
Less than 25% = 15 sq. ft. per parking stall
25% - 75% = 20 sq. ft. per parking stall
Greater than 75% = 30 sq. ft. per parking stall
Each row of parking stalls shall provide the required landscape area, however, it shall be the
applicant's right to place the islands near the buildings, throughout the parking, or at the end
of the rows away from the building. The Landscape Administrator may modify the island
requirement for each row in situations where it would appear beneficial to combine an
awkward or hazardous island into a larger island within the parking area. Planter islands
shall have a minimum width of 12' back -to -back if curbed or 13' edge -to -edge if no curb is
intended, and shall be equal to the length of the parking stall. Parking lot landscape areas do
count towards the total required interior landscape area.
a. Existing Trees: The Landscape Administrator may approve variations to the _
parking lot landscape island requirements in order to preserve existing trees in
interior parking areas. For existing trees the minimum width of the _ ap rking
lot landscape island shall be as follows:
Tree Size Min. Island Width Min. Dist. Tree to Curb
6" - 12" DBH = 12' minimum width 4'
Greater than 12" DBH = 18' minimum width 8'
b. Planting Requirements: Each individual parking
lot landscape island shall contain a minimum of one (1) canopy tree with the
remaining area in shrubs, ground cover, ornamental grasses, or seasonal color.
_ Parking lot landscape islands which have light poles for lighting the parking
areas may substitute two (2) understory /accent trees for the required canopy tree. All
required landscape areas shall be evenly distributed throughout the entire required
parking lot landscape areas.
Parking Garages: Parking garages shall be considered as buildings in accordance
with Section 3.3 herein.
3.5 VISIBILITY TRIANGLE: No requirements herein shall be deemed to require plantings
which would conflict with the visibility triangle at the intersection of public R.O.W. as
defined in the Subdivision Ordinance. Consideration should also be given to visibility at the
intersection of major driveways with the public R.O.W.
3.6 IRRIGATION REQUIREMENTS: All required landscape areas shall be irrigated by an
automatic irrigation system designed by a Licensed Irrigator, Landscape Architect or other
professional authorized by the State to design such systems. Natural meadows of wild
flowers or other native habitat shall not be required to be irrigated.

and maintained in accordance with the landscape irrigation rules promulgated by the
Texas Commission on Environmental Quality (TCEQ) or successor agency, as the
saine may be from time to time amended, and any applicable adopted City Plumbing
Codes.
11
b. Water Conservation: The City would like to promote the use of efficient irrigation
methods and practices. Where possible in planting beds, flood irrigation, porous
pipe or emitter /drip systems should be utilized. Where slopes do not allow flood
systems, flat spray heads should be utilized under shrubs rather than upward spray
heads on risers above shrubs. Lawn spray heads should have low precipitation rates,
run for longer periods of time, and water infrequently to promote deep root growth
for grasses.
C. Tree Irrigation Requirements: Trees shall be zoned separately and bubblers or
similar low -spray emission devices shall be utilized unless it is determined that it
would be detrimental to the sustainability of the tree, cause erosion, or can be
sufficiently irrigated by the proposed surrounding irrigation method.
4.0 EXISTING TREE PRESERVATION
4.1 GENERAL: One of the City's greatest assets is the existence of many specimen quality
native trees. One objective of this ordinance is the preservation of these trees while allowing
quality development to take place. All development must also comply with the City's Tree
Preservation Ordinance.
4.2 EXISTING TREE CREDITS: 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 by the Landscape Administrator at the time of inspection for a Permanent
Certificate of Occupancy.
a. Existing Tree Credit Calculation: 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 as follows:
Size of Tree Saved Canopy Understory
6" - 12" DBH = 1 or 2
Greater than 12" DBH = 2 or 3
b. Existing Tree Replacement: If the existing plants that were given credit toward
reducing the required plantings decline within two (2) growing seasons, the owner
shall replace that plant with quality plant material equal to the amount of the
declined plant.
5.0 PLANT MATERIAL
5.1 QUALITY STANDARD: All plant material shall be of No. 1 grade, free from plant disease,
of typical growth for the species, have a healthy, normal root system, rounded branching
pattern, and shall conform to the code of standards set forth in the current addition of
the American Standard for Nursery Stock.
5.2 RECOMMENDED PLANTS: Shown in Appendix 'A' is a list of recommended plants
within each plant material type. The applicant may propose plants other than those listed
if the plant seems appropriate for the intended use or the applicant maintains a plant care
program sufficient to properly care for the proposed plant material. The City reserves the
right to approve or disapprove required plants and planting through the Landscape
12
Administrator or City appointed Landscape Architect, horticulturist, or other person so
qualified.
53 SIZE REQUIREMENTS WHEN PLANTED: All plants shall equal or exceed the following
measurements when planted. Plants larger than specified may be used but use of such plants
shall not decrease the size requirements of other proposed plants.
a. Tree measurement: Canopy and understory trees with single trunks shall be
measured by caliper size one foot (1') above the ground line. Multi -Trunk trees shall
be measured by the height of the tree.
b. Minimum Sizes: Minimum plant size when planted shall be as follows:

difficulty on the applicant, that the situation causing the unnecessary hardship or practical
difficulty is unique to the affected property and is not self - imposed, that the variance will
not injure and will be wholly compatible with the use and permitted development of
adjacent properties, and that the granting of the variance will be in harmony with the
spirit and purpose of this ordinance. The decision of the City Council shall be final.

EXECUTIVE SUMMARY
Details
The City of Southlake is proposing revisions to the Landscape Ordinance No. 544 -A to
include the following revisions:
- Requirement for bubbler or similar low -spray emission devices on separate zone
for all new trees, with few exceptions;
- Compliance with the Texas Commission on Environmental Quality (TCEQ);
- Compliance with applicable City Plumbing Code as it relates to irrigation;
- and, new definitions added that relate to proposed revisions.
QUESTIONS & DISCUSSION
QUESTION: Who does this ordinance apply to? Does the statement under Section 3.1
apply to the whole document?
RESPONSE: Yes. The requirements of this ordinance apply to all new non - residential
construction and multi - family construction other than duplex uses. One
exception may be if a residential development had certain bufferyard
requirements.
QUESTION: Homeowners?
RESPONSE: Commercial development and where residential bufferyards are required
is the intention, not individual homeowners. We will confirm that with the
city attorney.
COMMENT: Section 6.1 also makes a reference to acreage and requirements
regarding qualified plans.
RESPONSE: That is not intended for residential single lots.
QUESTION: Would it apply to HOA's?
24
RESPONSE: If the area is a required landscape area or buffer. Again, I would need
legal confirmation.
QUESTION: Do bubblers help with run -off?
RESPONSE: Yes, they have a lower emission rate and concentrate on one area.
QUESTION: Are there bubblers in the medians?
RESPONSE: Yes, as well as drip irrigation.
QUESTION: You have replaced "planter" with "parking lot landscape "... why the
change?
RESPONSE: The updated term adds clarification for the developer.
QUESTION: Who determines tree size or if more than one may be required?
RESPONSE: The developer is required to provide a tree plan. The city landscape
administrator reviews the plan and may determine a waiver if applicable.
