(Ord. Nos. 19084; 25711)
SEC. 51P-225.121. LANDSCAPING IN THE INTERIOR NEIGHBORHOOD,
FREEWAY FRONTAGE, AND FRINGE TRANSITION DISTRICTS.
(a) Purpose. The process of development with its alteration of the natural topography,
vegetation, and creation of impervious cover can have a negative effect on the ecological balance of an
area by causing increases in air temperatures and accelerating the processes of runoff, erosion, and
sedimentation. The economic base of the city can and should be protected through the preservation and
enhancement of the unique natural beauty, environment, and vegetative space in this area. Recognizing
that the general objectives of this section are to promote and protect the health, safety, and welfare of the
public, the city council further declares that this section is adopted for the following specific purposes:
(1) To aid in stabilizing the environment's ecological balance by contributing to the
processes of air purification, oxygen regeneration, ground-water recharge, and storm water runoff
retardation, while at the same time aiding in noise, glare, and heat abatement.
(2) To provide visual buffering between land uses of differing character.
(3) To enhance the beautification of the city.
(4) To safeguard and enhance property values and to protect public and private
investment.
(5) To conserve energy.
(6) To provide habitat for wildlife.
(b) Application of section. This section applies to all districts in the State-Thomas Special
Purpose District except the Historic District. This section applies to all uses on a lot when an application
for a building permit for work on the lot is made, unless the application is for:
(1) restoration of a building that has been damaged or destroyed by fire, explosion,
flood, tornado, riot, act of the public enemy, or accident of any kind. For purposes of this subsection,
"restoration" means the act of putting back into a former or original state; or
(2) construction work that does not increase:
(A) the number of buildings on the lot;
(B) the number of stories in a building on the lot;
(C) the floor area of a building on the lot by more than 10 percent or 10,000
square feet, whichever is less; or
(D) the nonpermeable coverage of the lot by more than 2,000 square feet.
(c) Parks. In city parks over five acres in size, the director of parks and recreation shall
designate the boundaries of the lot for purposes of this section. The lot designated by the director must:
(1) wholly include the area on which the work is to be done; and
(2) be clearly delineated on plans submitted to the building official at the time the
application for a building permit is made.
(d) Binding effect. When this section becomes applicable to a lot, its requirements are
binding on all current and subsequent owners of the lot.
(e) Consistency. The city council shall, at a minimum, impose landscaping requirements
consistent with the standards and purposes of this section as a part of all ordinances establishing or
amending districts other than the Historic District in the State-Thomas Special Purpose District.
(f) Special exception. The board may grant a special exception to the landscaping
requirements of this section upon making a special finding from the evidence presented that strict
compliance with the requirements of this section will result in substantial financial hardship or inequity to
the applicant without sufficient corresponding benefit to the city and its citizens in accomplishing the
objectives and purposes of this section.
(g) Fee waiver. The board may waive the filing fee for a special exception under Subsection
(f) when the board finds that payment of the fee would result in financial hardship to the applicant. The
applicant may either pay the fee and request reimbursement as part of his appeal or request that the matter
be placed on the board's miscellaneous docket for predetermination. If the matter is placed on the
miscellaneous docket, the applicant may not file his appeal until the merits of the request for waiver have
been determined by the board.
(h) Landscape plan submission.
(1) If this section applies to a lot pursuant to Subsection (b), a landscape plan must
be submitted to the building official with the application for a building permit for work on the lot.
(2) If a landscape plan is required under Paragraph (1), the plan must be submitted to
and approved by the building official before a building permit is issued for the work. A landscape plan
submission must consist of two blueline or blackline prints. The plan must have a scale of one inch equals
50 feet or larger (e.g. one inch equals 40 feet, one inch equals 30 feet, etc.) and be on a standard drawing
sheet of a size not to exceed 36 inches by 48 inches. A plan which cannot be drawn in its entirety on a 36
inch by 48 inch sheet must be drawn with appropriate match lines on two or more sheets.
(3) A landscape plan required under this section must contain the following information:
(A) Date, scale, north point, and the names, addresses, and telephone
numbers of both the property owner and the person preparing the plan.
(B) Location of existing boundary lines and dimensions of the lot, the zoning
classification of the lot, and the subdistrict classification of adjacent properties. A vicinity map should
also be attached to or made a part of the plan.
(C) Approximate centerlines of existing water courses and the location of the
100-year flood plain, the escarpment zone, and geologically similar areas, if applicable; the approximate
location of significant drainage features; and the location and size of existing and proposed streets and
alleys, utility easements, driveways, and sidewalks on or adjacent to the lot.
(D) Project name, street address, and lot and block description.
(E) Location, height, and material of proposed screening and fencing (with
berms to be delineated by one-foot contours).
(F) Locations and dimensions of proposed landscape buffer strips.
(G) Complete description of plant materials shown on the plan, including
names (common and botanical name), locations, quantities, container or caliper sizes at installation,
heights, spread, and spacing. The location and type of all existing trees on the lot over six inches in
caliper must be specifically indicated.
(H) Complete description of landscaping and screening to be provided in or
near off-street parking and loading areas, including information as to the amount (in square feet) of
landscape area to be provided internal to parking areas and the number and location of required off-street
parking and loading spaces.
(I) An indication of how existing healthy trees proposed to be retained will
be protected from damage during construction.
(J) Size, height, location, and material of proposed seating, lighting,
planters, sculptures, and water features.
(K) A description of proposed watering methods.
(L) Location of visibility triangles on the lot (if applicable).
(i) Landscape plan review.
(1) The building official shall review each landscape plan submitted to determine
whether or not it complies with the requirements of this section. All landscape plans must comply with
the mandatory provisions in Subsection (j). In addition, all landscape plans must earn a minimum of 20
"points."
Points are awarded for specified landscape features and elements based on their relative value or
merit.
(2) The alternatives from which an applicant may select to achieve the minimum
point score needed for approval are referred to in this section as "design standards" and contained in
Subsection (k).
(j) Mandatory provisions.
(1) Trees.
(A) Tree planting zone. For purposes of this section, the "tree planting zone"
is that area parallel to and between two and one-half and four feet from the back of the projected street
curb.
[If the tree planting zone is in the parkway, the property owner must apply for a parkway landscape
permit before any required trees may be planted in the parkway. See Subparagraph (H) of this paragraph
for more details regarding the parkway landscape permit.]
(B) Number, location, and type of trees required. Each lot must have one or
more trees whose trunks are located wholly within the tree planting zone. The number of required trees is
determined by dividing the number of feet of lot frontage by 25. Fractions are rounded to the nearest
whole number, with .5 being rounded up to the next higher whole number. All required trees must be
recommended for local area use by the director of parks and recreation. If a property owner cannot obtain
a parkway landscape permit to locate a required tree in the parkway, he shall locate the tree in the
required front yard as near as practicable to the front lot line. If a lot has no front yard requirement and the
property owner cannot obtain a parkway landscape permit to locate a required tree in the parkway, the
property owner need not provide that required tree
.
(C) Minimum tree height and trunk caliper. Required trees must have a
minimum height of 14 feet, and a minimum trunk caliper of three and one-half inches measured at a point
12 inches above the root ball.
(D) Tree spacing requirements. Required trees must be spaced as uniformly
as practicable. The trunk of a required tree must be within 50 feet of another required tree.
(E) Minimum clearance above pavement. The property owner shall maintain
all trees to comply with the following minimum vertical height clearances over street and sidewalk
pavements:
(i) Thirteen and one-half feet above street pavement.
(ii) Eight feet above a public sidewalk and any sidewalk required by
this article.
(F) Tree grates required near sidewalks. Tree grates conforming to state
standards and specifications adopted to eliminate, insofar as possible, architectural barriers encountered
by aged, handicapped, or disabled persons, and of a size adequate to permit healthy tree growth must be
provided for all trees whose trunks are within 18 inches of a public sidewalk and any sidewalk required
by this article
.
(G) Private license granted. The city council hereby grants a private license
to the owners of all property in the State-Thomas SPD for the exclusive purpose of authorizing
compliance with the parkway landscaping requirements of this section. A property owner is not required
to pay an initial or annual fee for this license, although a fee may be charged for issuance of a parkway
landscape permit in accordance with Subparagraph (H) of this paragraph. This private license shall not
terminate at the end of any specific time period, however, the city council retains the right to terminate
this license whenever in its judgment the purpose or use of this license is inconsistent with the public use
of the right-of-way or whenever the purpose or use of this license is likely to become a nuisance.
(H) Parkway landscape permit.
(i) It is the responsibility of the property owner to apply for and
obtain a parkway landscape permit before locating trees, landscaping, or pavement other than for the
sidewalk required under this article in the parkway. An application for a parkway landscape permit, if

director of public works and transportation and accompanied by plans or drawings showing the area of the
parkway affected and the construction and planting proposed.
(ii) Upon receipt of the application and any required fees, the
director of public works and transportation shall circulate it to all affected city departments and utilities
for review and comment. If, after receiving comments from affected city departments and utilities, the
director of public works and transportation determines that the construction and planting proposed will
not be inconsistent with and will not unreasonable impair the public use of the right-of-way, the director
shall issue a parkway landscape permit to the property owner; otherwise, the director shall deny the
permit.
(iii) A property owner is not required to comply with any parkway
landscaping requirement of this section if compliance is made impossible due to the director of public

works and transportation is subject to immediate revocation upon written notice if at any time the director
determines that the use of the parkway authorized by the permit is inconsistent with or unreasonably
impairs the public use of the right-of-way. The property owner is not required to comply with any
parkway landscaping requirement of this section if compliance is made impossible due to the director's
revocation of a parkway landscape permit.
(v) The issuance of a parkway landscape permit under this section
does not excuse the property owner, his agents, or employees from liability in the installation or
maintenance of trees, landscaping, or pavement in the public right-of-way.
(2) Screening of off-street loading spaces and service areas.
(A) Off-street loading spaces and service areas on the lot must be screened
from:
(i) all public streets; and
(ii) all adjoining property whether abutting or directly across a street
or alley.
(B) The screening required under Paragraph (2)(A) must be at least six feet
in height measured from the horizontal plane passing through the nearest point of the off-street loading
space and may be provided by using any of the methods for providing screening described in Section 51-
4.602(b)(3), except that screening around service areas for trash collection must be screened only by a
masonry wall.
(3) Acceptable landscape materials.

minimum height of six feet, depending on the standard measuring technique for the species.
(ii) Small trees must have a minimum height of six feet.
(iii) Large shrubs must have a minimum height of three feet.
(C) For purposes of Paragraph (3)(B), "height" is measured from the top of the root
ball or, if the plant is in a container, from the soil level in the container.
(D) In satisfying the landscaping retirements of this section, the use of high-quality,
hardy, and drought-tolerant plant materials is recommended and encouraged.
(4) Soil requirements.
(A) Landscape planting areas in general must have the following soil depths

depth and 25 square feet of surface area (total of 75 cubic feet).
(B) Landscape planting areas located above underground buildings or
structures must have the following soil depths and dimensions:
(i) For each large shrub or small tree installation, a minimum of 30
inches of soil depth and 25 square feet of surface area (total of 62.5 cubic feet).
(ii) For each large tree installation, a minimum of 40 inches of soil
depth and 36 square feet of surface area (total of 120 cubic feet).
(C) The building official may waive the minimum soil requirements if a
landscape architect certifies that the proposed alternative soil depths and dimensions are sufficient to
support the healthy and vigorous growth of the plant materials affected.
(5) Protection of landscape areas. Required landscape areas must be protected from
vehicular traffic through the use of concrete curbs, wheel stops, or other permanent barriers.

at all times.
(7) Pedestrian scale lighting. Pedestrian scale lighting that provides a minimum
maintained average illumination level of 1.5 footcandles along all sidewalks on or adjacent to the lot and
adjacent to a public street must be provided. For purposes of this subsection, pedestrian scale lighting
means that the light emanates from a source that is no more than 14 feet above the grade of the sidewalk.
The design and placement of both the standards and fixtures must be approved by the director of public
works and transportation. Each property owner is responsible for the cost of installation, operation, and
maintenance of the lighting on his property or in the public right-of-way adjacent to his property.
(k) Design standards. In order to earn points under this subsection, landscape areas must be
placed in the front yard of a building site.
(1) Percentage of front yard area. One point is awarded for each three percent of the
total front yard area provided as landscape area to a maximum of 15 points if the landscape area:
(A) is at least 50 square feet;
(B) is covered with grass or other plant material as ground cover; and
(C) for every 100 square feet of landscape area, or fraction thereof has a
minimum of:
(i) one large canopy tree;
(ii) three small trees;
(iii) two small trees and one large shrub;
(iv) one small tree and two large shrubs; or
(v) three large shrubs.
(2) Parking concealment. Five points are awarded for providing all parking in
structures which:

(B) are totally underground.
(3) Existing tree credits. Existing healthy trees are categorized in accordance with
the definitions of this section and credited toward meeting design standards as follows:
(A) For each tree retained or relocated to the front yard of the building site or
to the street parkway, having a caliper equal to or greater than four inches but less than six inches, a credit
of one required large tree is allowed.
(B) For each tree retained or relocated to the front yard of the building site or
to the street parkway, having a caliper equal to or greater than six inches but less than 12 inches, a credit
of two required large trees is allowed.
(C) For each tree retained or relocated to the front yard of the building site or
to the street parkway, having a caliper equal to or greater than 12 inches, a credit of three required large
trees is allowed.
(4) Special amenities.

(ii) Three points are awarded when at least 50 percent of all outdoor pedestrian pavement
area consists of enhanced pavement. (Note: All pedestrian pavement material and
design must be approved by the director of public works and transportation.)
(B) Pedestrian facilities. One point is awarded for each one percent increment of lot area
covered by publicly accessible special pedestrian facilities and features such as
plazas, covered walkways, fountains, lakes and ponds, seating areas, and outdoor recreation facilities, up
to a maximum of five points.
(l) When landscaping must be completed.
(1) Except as otherwise provided in Paragraph (2) below, all landscaping must be
completed in accordance with the approved landscape plan before a certificate of occupancy may be
issued for any building on the lot.
(2) If the property owner provides the building official with documented assurance
that the landscaping will be completed within six months, the building official may issue one six-month
temporary certificate of occupancy and permit the property owner to complete his landscaping during the
six-month period. For purposes of this subsection, "documented assurance" means:
(A) a copy of a valid contract to install the landscaping in accordance with
the landscape plan within the six-month period; or
(B) a set of deed restrictions containing a covenant to install the landscaping
in accordance with the landscape plan within the six-month period. The deed restrictions must:
(i) expressly provide that they may be enforced by the city;
(ii) be approved as to form by the city attorney; and
(iii) be filed in the deed records of the county in which the land is located.
(3) If a temporary certificate of occupancy is issued under Paragraph (2) and, at the
end of the six-month period, no permanent certificate of occupancy has been issued because the
landscaping has not been installed in accordance with the landscape plan, the owner of the property is
liable to the city for a civil penalty in the amount of $200 a day for each calendar day thereafter until the
landscaping is properly installed. The building official shall give written notice to the property owner of
the amount owed to the city in civil penalties, and shall notify the city attorney of any unpaid civil
penalty. The city attorney shall collect unpaid civil penalties in a suit on the city's behalf.
(4) The civil penalty provided for in Subsection (c) is in addition to any other
enforcement remedies the city may have under city ordinances and state law.
(m) General maintenance.
(1) Required landscaping must be maintained in a healthy, growing condition at all
times. The property owner is responsible for regular weeding, mowing of grass, irrigating, fertilizing,
pruning, and other maintenance of all plantings as needed. Any plant that dies must be replaced with
another living plant that complies with the approved landscape plan within 90 days after notification by
the city.
(2) Any damage to utility lines resulting from the negligence of the property owner
or his agents or employees in the installation and maintenance of required landscaping in a utility
easement is the responsibility of the property owner. If a public utility disturbs a landscaped area in a
utility easement, it shall make every reasonable effort to preserve the landscaping materials and return
them to their prior locations after the utility work. If, nonetheless, some plant materials die, it is the
obligation of the property owner to replace the plant materials. (Ord. Nos. 19084; 25711)
