(a) Purpose.
The purpose of this article is to:
(1) Establish landscaping standards that preserve and enhance the character
of the city;
(2) Improve the compatibility between different adjoining uses; and
(3) Conserve water by promoting the use of native and drought-resistant
trees and shrubs.
(b) Applicability.
(1) The requirements of this article apply to all land in the city. All
site development plans, plats, and land development proposals are
subject to the minimum regulations and policies of this article.
(2) Exception.
The requirements of this article are not
applicable for modifications to nonresidential buildings where a building
expansion or redevelopment does not exceed the gross floor area of
the existing building by more than 10 percent or 3,000 square feet,
whichever is less.
(Ordinance 19-3690 adopted 4/23/19)
(a) Irrigation.
(1) General requirement.
All landscaping must be irrigated
or located within 100 feet of a private water outlet to which a hose
may be connected.
(2) Waivers of general requirement.
The administrator shall have the authority to waive or delay implementation of the requirements of subsection
(a)(1):
(A) When public improvements (e.g., water, sanitary sewer, drainage,
street facilities) have been authorized and scheduled which would
affect landscaping on a lot or tract; or
(B) For a temporary use which will be in operation for period of one
year or less.
(b) Public right-of-ways.
(1) Generally.
It shall be unlawful to set out, construct,
maintain or permit to be maintained any shrub or plant (excluding
trees), sign or structure, or any other obstruction having a height
of greater than three feet, as measured from the top of the curb of
the adjacent street, in the public right-of-way.
(2) Exemption.
Subsection
(b)(1) shall not apply to any government-owned traffic-control sign or signal, street sign, or mailbox provided that the structure does not:
(A) Interfere with the free passage of vehicles on the street;
(B) Interfere with pedestrian access on a sidewalk;
(C) Obscure the view of motor vehicle driver; or
(D) Otherwise create a traffic hazard.
(3) Trees in the public right-of-way.
All trees with a trunk
diameter greater than two inches measured three feet above ground
level that are within any of the parkway area shall be trimmed so
that no foliage is less than six feet above the top of the curb of
the adjacent street. No evergreen or coniferous species of tree shall
be allowed in the public right-of-way.
(c) Street tree planting and spacing.
Street trees planted
to fulfill the requirements of this article shall be:
(1) Planted no closer 10 feet from the curb, curb lines, sidewalks, fire
hydrants, underground utilities, overhead transmission lines, or other
utilities; and
(2) Planted no closer than 20 feet from any street corner, measured from
the point of nearest intersection of curb or pavement lines.
(d) Prohibited plant species.
Plant species that require
extensive irrigation, are invasive, or are not drought tolerant are
prohibited.
(e) Recommended plant list.
See the City of Plainview Recommended
Planting List.
(Ordinance 19-3690 adopted 4/23/19)
(a) Landscaping required.
(1) General requirements.
(A) New nonresidential uses and apartment developments shall be required
to have 10% of the development site landscaped.
(B) Landscaping, including all calculations used as the basis for the plan, shall be approved as part of section
14.12.006,
Site
Development Plans.
(2) Exception to general requirement.
The 10 percent landscaping requirement set forth in subsection
(a)(1)(A) may be reduced by up to 5 percent with site plan approval setting forth a plan for xeriscape landscape treatments, preservation of existing vegetation, and Water-Wise irrigation systems for at least two-thirds of total area of the development.
(3) Recommended plantings.
The city highly recommends that all landscaping that is planted as part of a new development shall be from the recommended plant list per section
14.07.002(e),
Recommended Plant List; however, the city requires that no plants shall require extensive irrigation, are invasive, or are not drought tolerant as per section
14.07.002(d),
Prohibited
Plant Species.
(b) Landscaping location requirements.
(1) At least 50 percent of all required landscaping shall be located
between the front of a primary building and the street right-of-way.
(2) Landscaping shall be comprised of a mixture of native trees, shrubs,
and succulent plants, using methods that promote water conservation
and plant sustainability.
(3) Landscaping may be clustered or placed in smaller islands, provided
that the landscaping is sustainable when located in parking lots and
near streets.
(4) The administrator may approve a deviation from the 50 percent criteria
in order to:
(A) Preserve existing vegetation on another side of the site;
(B) Provide additional buffering in a critical location where it may
be required, such as along a rear property line; or
(C) Create an amenity area in another portion of the site.
(c) Downtown District.
The 50 percent requirement of subsection
(b)(1), above, shall not apply to the Downtown District (DT) due to the “build to” setback requirement. In the Downtown District, landscaping may be dispersed across the entire site.
(d) Landscaping calculation guidelines.
(1) Clustering of vegetation.
(A) The 50 percent landscaping requirement of subsection
(b)(1), above, does not preclude the clustering of vegetation or the even distribution of landscaping. Landscaping should be placed within areas that will ensure the longevity of the landscaping and efficient irrigation that promotes water conservation;
(B) Where practical, it is the preference of the city to maintain existing
trees and other vegetation;
(C) Bufferyard landscaping located between the front building facade
and a street shall be counted toward fulfilling the bufferyard and
50 percent landscaping requirements;
(2) Location of vegetation.
Landscaping will be strategically
located, and vegetation preserved, in locations that simultaneously
satisfy the requirements of multiple landscaping requirements; and
(3) Site development plans.
Any landscape plan submitted via section
14.12.006,
Site Development Plans, must
contain calculations and planting schedules that demonstrate how each
landscaping requirement has been satisfied and the amount of existing
vegetation credits that are proposed. Existing areas to be preserved
shall be adequately denoted and described on the landscape plan, with
details provided about the preservation of these areas during construction.
(e) Landscape design criteria.
(1) All plant material must meet specifications of the American Association
of Nurserymen (AAN) for No. 1 grade.
(2) All plants shall be sized as set out in table 14.07.003,
Minimum Planting Size Requirements, with the exception of plants required in order to satisfy the bufferyard requirements set out in section
14.07.004,
Bufferyards.
(A) When opaque screening or a bufferyard is required to be a specific
height, the size of landscaping shall be sufficient to satisfy that
requirement at the time of planting.
(B) Required plant height necessary to satisfy the applicable bufferyard
requirements may be reduced by the height of an earthen berm, if landscaping
is installed on the berm or above the natural grade.
(3) Where larger sized plants are required to satisfy bufferyard requirements,
the minimum required plant size shall comply with the more stringent
requirement.

(Ordinance 19-3690 adopted 4/23/19)
(a) Generally.
The bufferyards required by this chapter
are based on the amount of screening they provide, which are classified
from less screening (Type A) to more screening (Type D), depending
on the types and intensity the adjacent land uses and/or zoning district.
(b) Bufferyard types.
(1) There are four types of bufferyards, each of which vary in the width
of the bufferyard and the numbers and types of plants that are required
per 100 linear feet, or portion thereof.
(2) The minimum planting requirements for each type and composition of
bufferyard are set out in table 14.07.004(A), Bufferyard Classifications.
(c) Classification of bufferyards.
Bufferyards may be classified
as:
(1) Structural bufferyards.
Structural bufferyards are those
that include a fence or wall to achieve the required level of screening
or preferred for privacy or security; and
(2) Natural bufferyards.
Natural bufferyards are those that
include an earthen berm, a geologic grade change, an arroyo, or a
higher density of plant materials to achieve the required level of
screening.

Table notes:
|
1 An earthen berm, wall, or fence
is not required for natural bufferyard.
|
2 Special use permit approval may
require additional bufferyard requirements as a condition of approval.
|
(d) Bufferyards in specific locations.
(1) Between districts.
Structural bufferyards are the preferred
composition along a district boundary that is not a street, or where
there is a specific privacy or security need that requires a wall
or fence.
(2) Between mixed housing types and uses.
Structural or
natural bufferyards may be used between mixed housing types and mixed
uses within a development.
(3) Adjacent to land zoned Single-Family Residential (R-1).
Natural bufferyards are preferred where practical to reinforce the
rural or suburban character of the district.
(4) Along resource features and recreation uses.
Natural
bufferyards are desired along natural areas and floodplains to provide
open space and enhance water quality and public safety.
(e) Exemptions.
A parcel proposed for development, redevelopment,
or substantial improvement may be exempt from the requirement to provide
a bufferyard under the following conditions:
(1) When there is an elevation difference between two adjacent properties
that is six feet or greater; or
(2) When the parcel proposed for development, redevelopment, or substantial
improvement is separated from the adjacent property by a natural or
man-made area that meets or exceeds the level of screening required
by the applicable bufferyard.
(f) Credits for existing landscaping improvements.
(1) Generally.
Existing trees, fences, and landscape or
retaining walls that meet, in part but not in whole, the bufferyard
requirements set out herein, may be counted toward a bufferyard requirement,
provided that the trees and landscaping are in good health or the
fences or walls are structurally sound.
(2) Existing landscaping credit.
Credit shall be given for
existing trees and landscaping within bufferyards and perimeter yards.
(g) Zoning district boundary bufferyard standards.
(1) Generally.
Set out in table 14.07.004(B), Zoning
District Boundary Bufferyard Standards, is the classification
of bufferyards that are required between zoning districts that are
not separated by a public street right-of-way.
(2) Interpretation of the table.
(A) The table is a matrix in which all zoning districts are grouped into
categories of similar land use intensities.
(B) The rows indicate the zoning of the parcel proposed for development
and the columns indicate the zoning of the adjacent property or properties.
(C) Where “–” is found, no bufferyard is required.

(3) Relationship to other bufferyard requirements.
If bufferyards
are required by another section of this chapter along property boundaries
that are also district boundaries, then the greater bufferyard requirement
shall prevail.
(h) Bufferyard fencing and screening.
(1) Orientation.
Where a fence is used to provide a buffer,
the finished side of all fences shall face outward toward any adjacent
rights-of-way or the property that is being buffered. All support
posts and stringers shall face inward toward the property upon which
the fence is located, or the development being screened.
(2) Construction materials.
Any screening wall or fence
qualifying as a bufferyard shall be constructed of wood, masonry or
reinforced concrete which does not contain openings constituting more
than 40 square inches in each one square foot of wall or fence surface,
and the surface of such wall or fence shall constitute a visual barrier.
All wall or fence openings shall be equipped with gates equal in height
and screening characteristics to the wall or fence.
(Ordinance 19-3690 adopted 4/23/19)
(a) Generally.
All plant material shall be maintained at
all times in a living and growing condition. Any landscaping material
that dies shall be replaced with healthy material.
(b) Trimming.
Any tree or other form of landscaping overhanging
a public alley, street, or highway shall:
(1) Be trimmed by the owner, agent or occupant of the property on which
the landscaping is planted so that there is a clear height of 18 feet
above the surface of the street, alley or highway and eight feet above
the sidewalk surface, that is unobstructed;
(2) If a tree or any other landscaping in any way causes a hindrance
to the general public, or in any way endangers the security or usefulness
of any public street, right-of-way, highway, alley, utility, or sidewalk,
it may be declared to be a public nuisance; and
(3) If the owner of such tree or landscaping does not correct or remove such nuisance within 30 days of written notification, the city shall cause the nuisance to be corrected in accordance with the requirements set out in article
14.14,
Enforcement and Remedies.
(c) See also section
14.02.006,
Planned Development (PD) District
Regulations, and section
