Topping is defined as severely cutting back limbs to stubs
within the tree's crown to such a degree as to remove the
normal canopy and disfigure the tree. Good pruning
practices rarely remove more thanl/4 to 1/3 of a tree's
crown. Topping starves the tree of needed nutrients
produced by leaves in the crown, increases vulnerability to
insects and disease, creates weak limbs, rapid new growth,
and disfigures the natural shape of the tree. Other
common terms for topping include stubbing, heading,
heading-back, stubbing off, tipping, lopping, or roundover.
All forms of topping are prohibited by this ordinance.

Existing wetlands, rock outcroppings, groves of trees,

f:r~
Applicability: A landscape plan is required for all commercial,
industrial, office, and multi-family development, redevelopment,
additions, or changes in use. A landscape plan is also required for
all common lots in all subdivisions. The landscape plan is
required as part of all applications for a Conditional Use Permit
(CUP), Preliminary Plat (PP), Final Plat (FP), or Certificate of
Zoning Compliance (CZC). The landscape plan may be on the
same site plan used to show parking layout, setback compliance,
etc. A preliminary landscape plan review is recommended prior
to submission for all developments, but is not required.

Landscape Plan Preparation: Preparing a landscape plan requires ~.'
special skills. Landscaping involves more than a simple arrangement
of plants with irrigation; plants are not haphazardly placed in a way
the fills up leftover space. Landscape plans should be artfully and
technically organized in a way that conveys coherence, design, and
organization. The landscaping should enhance the physical
environment as well as the project's aesthetic character. Also,
requiring plans prepared by a landscape professional minimizes the
likelihood of trees dying or interfering with other adjacent site
features.
Therefore, All landscape plans shall be prepared by a landscape
architect, landscape designer, or qualified nurseryman.
12-13-6-4 Landscape Plan Modification: The approved Landscape Plan
shall not be altered without prior approval of the Planning and
Zoning Department. No significant field changes to the plan are
permitted. Prior written approval of all material changes is required.
All approved changes to the landscape plan must be documented
prior to issuance of a Certificate of Occupancy.

with high winds or other situations that make staking desirable. If
trees are staked, the stakes must be removed within 12 months to
prevent damage to the tree.
~
12-13-7 -8 Mulch: An organic mulch such as bark or soil aid shall be applied
to all planting areas for moisture retention, weed control, and
moderation of soil temperatures. Impermeable plastic weed barrier
is prohibited under the mulch, because it restricts water and oxygen
to the roots. GraveVrock mulch is prohibited in required landscape
areas as per 4.13.B.
~
12-13-7..9 Curbing: All planting areas that border driveways, parking lots,
and other vehicle use areas shall be protected by curbing, wheel
Ti stops, or other approved protective devices. Such devices shall be
a minimum of thirty (30) inches from all tree trunks to prevent cars
from damaging tree trunks.
12-13-7-10 Utilities: The following standards apply to the planting of trees
near existing utilities and to trenching for new utilities near existing
trees:
A. Overhead Utilities: Only Class I trees in the Recommended
Plant List may be planted under or within ten (10) lateral
feet of any overhead utility wires.
B.
Underground Utilities: All trees shall be planted outside of
any easement that contains a City water or sewer main,
unless written approval is obtained from the City Engineer.
If any utility easement precludes trees required by this
ordinance, the width of the required 'l:2.uffer shall be increased
to accommodate the required trees.
~~
c. Trenching: New underground utilities shall stay outside of
the dripline of existing trees if trenched, or be tunneled a
minimum of three (3) feet below existing grade within the
tree's dripline. The guiding principle is that no root two (2)
inches or larger shall be cut. Note: This requirement is for
placement of new utilities and does not affect the City's
ability to access existing utilities for repair and maintenance.

12-13-7-11 Erosion Control: Soil and slope stabilization shall result from the
landscape installation.
12-13-7-12 Berms: Berm slopes shall not exceed 2:1 (horizontal: vertical). 3:1
maximum slopes are recommended. Grass that requires mowing
shall not be used on slopes steeper than 3: 1.
12-13-7-13 Water Efficiency: The landscape plan shall provide for water
efficient landscaping as follows:
A. Lawn Areas: Where appropriate and on sites where other
landscape options can be incorporated, large expanses of
lawn are discouraged due to its high water consumption.
B. Mulch: Mulches shall be organic and broad uses of
graveVrock mulch are restricted as per Section 4.8. Gravel
does not retain water , reflects heat, and causes greater
stress on trees and shrubs. Organic mulch retains water for
a longer period of time for plants.
C. Irrigation: Irrigation systems shall be designed for water
efficiency as regulated by Section 5 of this Ordinance.
D. Native Plants: Native and other low-water-use plants are
encouraged. The Approved Plant List as per Section 4.1
shows the general water requirements of the trees.

12-13-10 STREET BUFFERS
I~
.
12-13-10-1 Purpose: Landscape buffers along streets are required in order to
improve the visual quality of the streetscape, to soften the impact
of parking lots, to unify diverse architecture, and to carry out the
Comprehensive Plan policies related to promoting attractive
roadways and street beautification.
~
12-13-10-2 Location: All required buffers shall be located beyond any street

be measured from the property line and not from the sidewalk or
curb. If detached sidewalks are provided as per Section 7.8, the
buffer may be measured from the back of curb when it can be
demonstrated that there is no opportunity for expansion of the
street section within the right-of-way; the buffer width must exclude
the width of the sidewalk. No fences are permitted within required
"II street buffers.
12-13-10-3 Applicability: Street buffers shall be required at all subdivision
boundaries (i.e. commercial, industrial, office, and residential) and
all commercial, industrial, and office developments. Single-family
residential, duplex, and townhouse lots are exempt from required
street buffers. All subdivision street buffers must be on a common
lot, maintained by a home-owners or business-owners association,
as applicable.
12-13-10-4 Buffer Size: The required width of the landscape buffer is
calculated based on the Ada County Long Range Highway and
Street Map (and future updates) as follows. Note: Residential
Collectors do not have a required street buffer.

shall the width be reduced to less than ten (10) percent of the
depth of the lot without a Variance, except in Old Town.
12-13-10-6
Street Trees: All required landscape street buffers shall be
planted with trees and shrubs, lawn, or other vegetative
groundcover, with a minimum density of one (1) tree per thirty-
five (35) linear feet. If this calculation results in a fraction .5 or
greater, round up to an additional tree. If the calculation results
in a fraction less than .5, round the number down.

Parkways and Detached Sidewalks: Detached sidewalks are
required along all arterial streets in new developments at the edge
of existing city limits. The minimum width of the parkway area
between the curb and the sidewalk is five (5) feet. Tree plantings
within parkways less than ten (10) feet wide are restricted to
Class II trees. Existing developments and infill projects may
waive the requirement for detached sidewalks to match
surrounding conditions. If detached sidewalks are provided on
local streets in residential subdivisions, the minimum sidewalk
width may be reduced to four (4) feet.

12-13-10-9 Landscaping within Right-of-Way: If the unimproved street
~ right-of-way is greater than thirteen (13) feet from edge of
~ pavement to edge of sidewalk or property line, and road widening
project is not in the Ada County Highway District (ACHD) 5-
year funded plan, developer shall maintain a ten (10) foot wide
gravel shoulder and landscape the remainder with lawn or other
vegetative groundcover. This will require a license agreement
between the property owner and ACHD.
12-13-10-10 Impervious Surfaces: Allowed impervious surfaces include
driveways, signs and walkways. Vehicle display pads and other
related impervious surfaces are prohibited in the required street
buffer.

12-13-11-2 Perimeter Landscaping: The following standards apply to all
interior lot lines, side or rear, adjacent to parking lots or other vehicular use areas,
including driveways:
-.-
~.
A. Purpose
Perimeter landscaping defines parking, loading, and other vehicular use
ar~as and prevents two adjacent lots from becoming one large expanse of
paving. This requirement does not hinder the ability to provide vehicular
access between lots, nor does it prohibit t~ommercial or industrial
developments with back-to-back truck docks from sharing paved loading
areas.
B. Size and Location
Provide a five (5) foot minimum perimeter landscape strip along all
interior lot lines that are adjacent to parking, loading, or other paved
vehicular use areas, including driveways, vehicle sales areas, truck
parking areas, bus parking areas, and vehicle storage areas.
c. Landscaping
The perimeter landscape strip shall be planted with one (I) tree per thirty
five (35) lineal feet and shrubs, lawn, or other vegetative groundcover.
12-13-11-3 Internal Landscaping: Interior parking lot landscaping shall be
required on any parking lot with more than twelve (12) spaces.

B. Planter Size
Landscape planters shall contain a minimum of fifty (50) square feet
and the planting area shall not be less than five (5) feet in any
dimension, measured inside curbs. The only exception to the five-
foot minimum dimension is at the tip of triangular planters located
at the end of rows of angled parking.
c. Parking Spaces
No linear grouping of parking spaces shall exceed twelve (12) in a
row, without an internal planter island.
D. Parking Lot Layout
Interior landscaping shall, insofar as possible, be used to delineate
and guide major traffic movement within the parking area so as to
prevent cross-space driving. Interior landscape planters shall be
~spaced as evenly as feasible and at the ends of rows of parking
throughout the lot to consistently reduce the visual impact of long
rows of parked cars.
E.
Trees Required
Ea:~h interior planter that serves a single row of parking spaces shall
be landscaped with at least one (1) tree and shall be covered with
low shrubs, lawn, or other vegetative groundcover. Each interior
planter that serves a double row of parking spaces shall have at least
two (2) trees and shall be covered with low shrubs, lawn, or other
vegetative groundcover. Deciduous shade trees must be pruned to
a minimum height of eight (8) feet above the adjacent parking areas.
Evergreen trees and Class III trees are prohibited in interior
planters.
.
F. Design Flexibility
In park1.ng areas where the~strict application of subsection 8.3.A will
seriously limit the function and circulation of the lot, up to fifty
(50) percent of the required landscaping may be located near the
perimeter of the paved area to emphasize entrance corridors or
special landscape areas within the general parking area. Such
required interior landscaping which is relocated shall be in addition
to perimeter landscape and right of way screening requirements.
Landscape Ordinance - Final 11/28/00

G. Industrial Exclusion
Industrial parking, storage, and loading areas are specifically
excluded from the interior landscape requirements, but shall still be
required to meet all perimeter and right of way landscape and
screening requirements.
12-13-11-4 Existing Parking Lot Applicability
Existing parking lots shall be required to conform to this section
based upon the following guidelines:
i
A. For restriping, parking lot overlays, or parking lot
replacement less than 25%, no additional landscaping shall
be required.
B. For parking lot replacement that is 25-50% of the parking
area, Perimeter and Right of Way Landscaping as required by
the Ordinance shall be installed.
c. For parking lot replacement that is greater than 50% of the
parking area, all current landscape standards of the
Ordinance shall be met.
D. If the location of existing buildings or other structures
prevents conformance with the requirements of this section,
or if its implementation would create a non-conformity with
parking standards, the Planning Director shall determine how
the Code is to be applied.
12-13-12 BUFFERS BETWEEN DIFFERENT lAND USES
12-13-12-1 Purpose: The landscape requirements in this section are
intended to ensure incompatible, adjoining land uses are
adequately protected and are provided an appropriate amount of
land separation to conduct permitted uses without causing
adverse impact. An incompatible land use is defined as one that is
more intensely developed than its neighbor (as defined herein
under section 9.4) and typically involves minimizing potential
nuisances such as noise, dirt, litter, glare of lights, or other
objectionable activities. The buffers are required along the entire
contiguous property line.
Landscape Ordinance - Final 11/28/00
Page 28
:t..,-:
~
OJ
~
12-13-12-2 Responsibility for Buffer Construction: The required buffer
between different land uses shall be provided by the higher
intensity use and shall be located on the building site of the
higher intensity use, except as determined otherwise by the
Planning Director after written request. If a lower intensity use is
proposed adjacent to an existing higher intensity use with no
buffer, the lower intensity use must provide the required buffer.
12-13-12-3 Buffer Materials: The materials within the required buffer
between incompatible land uses are regulated as follows:
A. Mix of Materials
All buffer areas shall be comprised of, but not limited to, a
mix of evergreen and deciduous trees, shrubs, lawn, or
other vegetative groundcover. Fences, walls and berms may
also be incorporated into the buffer area.
-c
I:l~
~I.:
it'
~
B.
Barrier Effectiveness
The required buffer area shall result in an effective barrier
within three (3) years and be maintained such that sixty
percent (60%) or more of the vertical surface is closed and
prevents the passage of vision through it. Trees may be
spaced closer as necessary to achieve this goal.
c.
Buffer Walls
Where existing or proposed adjacent land uses cannot be
adequately buffered with plant material(s), the City may
require inclusion of a wall, fence, or other type of screen
that mitigates noise and/or unsightly uses. If a wall or
fence at least six (6) feet tall is provided, the planting
requirement may be reduced to at least one tree per 35
lineal feet, plus shrubs, lawn, or other vegetative
groundcover must be provided within the buffer area, in
lieu of the requirements of subsection B.
~
D.
Chainlink Fencing
Chainlink or cyclone fencing, with or without slats, is
prohibited within required buffers between different land
uses. Chainlink may be used beyond the required buffer.
Chainlink fencing does not qualify as a screening material;
Landscape Ordinance - Final 11/28/00
Page 29
~;\I
~~
~1
~
therefore the buffer must still be landscaped as per
subsection B, even if a chainlink fence is provided.
12-13-12-4 Land Use Intensity Classifications: The table below is
intended to provide a general classification of land use intensities for
commonly proposed developments and is not a comprehensive list. If
a land use is not listed, the intensity classification shall be
determined by the Planning Director based upon the nearest use
listed.

c) The bu.ffers between land uses are required only along contiguous lot lines.
If incompatible land uses are across a public street from one another, the street
buffer r~uirements of Section 7 apply.
~
12-13-12-6 Pedestrian Access: Landscaping and screens shall not eliminate
pedestrian access from residential development to abutting
commercial districts and vice versa.
12-13-12-7 Existing Partial Buffers: If all or any part of the buffer has been
provided on the adjacent property, the proposed use must provide
only that amount of the buffer which has not been provided on
the adjacent property.
12-13-1.2-8 Relationship to Parking Lot Perimeter Requirements: All
~ buffers between different land uses may include any required
~ perimeter parking lot landscape strips (see Section 8.2) when
~ calculating the minimum width of the buffer.

B. Grade Changes
Grade changes greater than six (6) inches are prohibited
within the dripline of existing trees.
c.
Compaction
Most of the damage to trees caused by machinery occurs to
the root system from compaction of the soil. A simple
fence or barrier that encloses the entire area beneath the
tree canopy shall be in place prior to construction.
:1.
D. Utilities
New underground utilities to be placed within the dripline
of existing trees shall be installed as per Section 4.10.C of
this Ordinance.
12-13-13-6 Mitigation Trees: Mitigation is required for all existing trees
four (4) inch caliper or greater that are removed from the site
with equal replacement of the total calipers lost on site. Example:
two (2) IO-inch caliper trees removed may be mitigated with four
(4) 5-inch caliper trees, five (5) 4-inch caliper trees, or seven (7)
3-inch caliper trees. Existing prohibited trees within the street
buffer or parking lot need not be mitigated for if they are
removed. Existing dead, dying, or hazard trees need not be
mitigated for if they are removed. The City of Meridian Parks
Department arborist shall certify any dead, dying, or hazard trees
prior to removal. Trees that are required to be removed by
~ another. governmental agency having jurisdiction over the project
need not be mitigated for.
ri
12-13-13-7 Required Landscaping: Existing trees that are retained or
relocated on site may count toward the required landscaping.
Mitigation trees are in addition to all other landscaping required
by this ordinance.
12-13-1~-8 Incentives: The Planning Director may allow a reduction up to
ten percent (1 0%) of the required parking spaces to accommodate
existing trees. Approval of the reduction in required parking
must be obtained in writing prior to submittal of plans.

12-13-14 STORMWATER INTEGRATION
12-13-14-1 Purpose: The City encourages the incorporation of vegetated,
well-designed stormwater filtration swales into required landscape
areas where topography and hydrologic features allow. Such
integrated site designs can improve water quality and provide a
natural, effective form of flood and water pollution control.

12-13-18 ALTERNATIVE COMPLIANCE
~
Purpose: The intent of this section is to encourage creative
solutions to land-use problems. The City recognizes that the
specific requirements of this landscape ordinance cannot and do
not anticipate all possible landscape situations. In addition, the
City :iecognizes that there may be landscape proposals which
conform to the purpose, intent, and objectives of the landscape
regulations but were not anticipated in the specific regulations.
Therefore, the Department of Planning & Zoning may allow for a
method of alternative compliance in the event of these situations.
12-13-18-1
II
12-13-18-2 Conditions: Requests for alternative compliance are allowed only
when one or more of the following conditions are met:
A. Topography, soil, vegetation, or other site conditions are
such that full compliance is impossible or impractical.
B. The site involves space limitations or an unusually shaped
lot.
C.
Due to a change of use on an existing site, the required
landscape buffer is larger than can be provided.
.
D. Additional environmental quality improvements would
result from the alternative compliance.
II
E.
Safety considerations make alternative compliance
desirable.
II
F. Other regulatory agencies or departments having
jurisdiction are requiring design standards that conflict
with the requirements of this Ordinance.
y
G.
The proposed design includes innovative design features
based on "New Urbanism," "Neo-Traditional Design," or

other current planning topics.
H. The applicant is proposing a pond with a permanent water
level in a required landscape area.
12-13-18-3 Submittal Requirements: The following items are required to
apply for Alternative Compliance. Note: if a project is being
submitted as a Planned Development, a separate application for
Alternative Compliance is not required.

to illustrate the proposed method of alternative
compliance.
C. An application fee as set by City Council.
.
12-13-18-4 Design Flexibility: The Planning Director or the Director's
designee shall have authority to vary on a case-by-case basis the
required landscaping where an alternative requirement would
address unique site conditions and allow design flexibility while
still serving the intent of the Landscape Ordinance.
12-13-18-5 Variance: If compliance with this ordinance is not possible and
there is no feasible proposal for alternative compliance which is,
in the judgement of the Planning Director, equal or better than
normal compliance, the applicant must apply for a Variance in

CHAPTER 13
LANDSCAPING
SECTION 12-13-1: SHORT TITLE: This chapter may be cited as
"Landscaping Ordinance."
SECTION 12-13-2: GENERAL PROVISIONS - INTENT AND PURPOSES:
12-13-1 INTENT AND PURPOSE: To promote landscaping in the City of
Meridian that will improve community livability, preserve the quality of life, and
enhance the aesthetic quality, economic viability, and environmental health of the
city.
12-13-2 BACKGROUND: The City of Meridian is facing many problems as
a result of the explosive growth of the previous decade. These problems include:
a. Extensive parking lots that are unscreened and unshaded;
b. Hot streets, buildings, and parking lots which cause high energy
consumption;
c. Unscreened loading docks and outdoor storage areas;
Landscape Ordinance - Final 11/28/00 Page 7
d. Air quality concerns;
e. Unwanted noise;
f. Reflection and glare from the abundance of glass, metal, and plastic used in
buildings, automobiles, and signs; and
g. Wind/water erosion, which causes water pollution.
12-13-3 BENEFITS: There is abundant research available about the benefits
of landscaping in communities. This is by no means an exhaustive summary, but
following are some of the major benefits that our community would receive through a
comprehensive landscape ordinance. Most people think of landscaping only in terms
of aesthetic or beautification benefits, which certainly exist, but there are also proven
economic and environmental benefits to the community as summarized below.
1. Aesthetic Benefits:
a. Screened parking lots, loading docks, trash receptacles, and
storage areas;
b.' Reduced glare and reflected light;
C. Shade for buildings, streets and parking lots;
d. Defines outdoor spaces;
e. Seasonal color, including flowers and fall color;
f. Frames and reveals desired views;
g. Adds natural elements to otherwise harsh urban development;
h. Attracts birds and other urban wildlife;
i. Helps maintain the rural feel of the city; and
Visually ties the city to the surrounding countryside.
Landscape Ordinance - Final 11 /28/00 Page 8
2. Economic Benefits:
a. More profitable business districts;
b. Consumers report greater willingness to pay for products in well
landscaped commercial areas;
C. Attracts new businesses;
d. Encourages redevelopment and economic investment in the local
community;
e. Office and retail space leases more quicldy;
f. Reduces energy consumption for air conditioning, etc.; and
g. Increased residential property values.
3 Environmental Benefits:
a. Prevents soil erosion;
b. Removes particulate pollutants from the air;
C. Provides extra oxygen in the atmosphere;
d. Removes carbon dioxide from the air;
e. Improves soil condition;
f. Purifies water supplies, especially storm runoff;
g. Reduces unwanted noise; and
h. Controls and directs excessive wind.
12-13-4 COSTS TO DEVELOPERS AND PROPERTY OWNERS: The
City of Meridian recognizes that landscaping can be a significant expense to business
people and residents. At the same time, landscaping improves the livability of
residential neighborhoods, enhances the appearance and customer attraction of
Landscape Ordinance - Final 11/28/00 Page 9
commercial areas, increases property values, improves the compatibility of adjacent
uses, screens undesirable views, and can reduce air and noise pollution. The intent of
these regulations is to achieve a balance between the right of individuals to develop
and maintain their property in a manner they prefer and the right of City residents to
live, work, shop, and recreate in pleasant, healthy, and attractive surroundings.
12-13-5 DEFINITIONS:
BERM: An earthen mound designed to provide visual interest,

USE: its buildings is designed, arranged, or intended results in a
greater degree of measurable noise, odor, light, vibration or
other potential public nuisance than an adjacent property,
it shall be deemed a higher intensity use.
IMPERVIOUS A surface that has been compacted or covered with a layer
SURFACE: of material so that it is highly resistant to infiltration or
absorption by water. It includes surfaces such as
compacted sand or clay as well as most conventionally
surfaced streets, roofs, sidewalks and parking lots.

TOPPING: Topping is defined as severely cutting back limbs to stubs
within the tree's crown to such a degree as to remove the
normal canopy and disfigure the tree. Good pruning
practices rarely remove more than l/4 to 1/3 of a tree's
crown. Topping starves the tree of needed nutrients
produced by leaves in the crown, increases vulnerability to
insects and disease, creates weak limbs, rapid new growth,
and disfigures the natural shape of the tree. Other
common terms for topping include stubbing, heading,
heading -back, stubbing off, tipping, lopping, or roundover.
All forms of topping are prohibited by this ordinance.
UNIMPROVED Existing wetlands, rock outcroppings, groves of trees,

12-13-6 LANDSCAPE PLAN
12-13-6-1 Applicability: A landscape plan is required for all commercial,
industrial, office, and multi -family development, redevelopment,
additions, or changes in use. A landscape plan is also required for
all common lots in all subdivisions. The landscape plan is
required as part of all applications for a Conditional Use Permit
(CUP), Preliminary Plat (PP), Final Plat (FP), or Certificate of
Zoning Compliance (CZC). The landscape plan may be on the
same site plan used to show parking layout, setback compliance,
etc. A preliminary landscape plan review is recommended prior
to submission for all developments, but is not required.
Landscape Ordinance - Final 11/28/00 Page 14
12-13-6-2 Submittal Requirements: All landscape plans shall comply with
the requirements for size, scale, number of copies, and contents as
detailed in the application form.
12-13-6-3 Landscape Plan Preparation: Preparing a landscape plan requires
special skills. Landscaping involves more than a simple arrangement
of plants with irrigation; plants are not haphazardly placed in a way
the fills up leftover space. Landscape plans should be artfully and
technically organized in a way that conveys coherence, design, and
organization. The landscaping should enhance the physical
environment as well as the project's aesthetic character. Also,
requiring plans prepared by a landscape professional minimizes the
likelihood of trees dying or interfering with other adjacent site
features.
Therefore, All landscape plans shall be prepared by a landscape
architect, landscape designer, or qualified nurseryman.
12-13-6-4 Landscape Plan Modification: The approved Landscape Plan
shall not be altered without prior approval of the Planning and
Zoning Department. No significant field changes to the plan are
permitted. Prior written approval of all material changes is required.
All approved changes to the landscape plan must be documented
prior to issuance of a Certificate of Occupancy.
12-13-7 MINIMUM DESIGN STANDARDS & INSTALLATION
12-13-7-1 Approved Plant Material: The publication titled Tree Selection
Guide for streets and landscapes throughout Idaho by the Urban

edition) is hereby adopted by this reference as the City of Meridian
list of approved and prohibited plant material. The publication
categorizes the trees by size as Class I, Class II, or Class III trees.
The City recognizes that new plant varieties are being produced
every year and will consider other species not listed in the
publication. Copies of the publication will be available at the
Planning and Zoning Department.
12-13-7-2 Prohibited Plant Material: The plants listed under "Trees not
permitted for Rights -of -Way Property Planting" are prohibited from
Landscape Ordinance - Final 11/28/00 Page 15
being planted along any street or within any parking lot regulated
by this ordinance. The only exception is that conifers may be
planted in street buffers around residential subdivisions, and in
buffers along I-84.
12-13-7-3 Minimum Plant Sizes: The following are minimum plant sizes for
all required landscape areas:
Shade Trees: 2 inch caliper minimum
Ornamental Trees: 2 inch caliper minimum
Evergreen Trees: 6-7 foot height minimum
Woody Shrubs: 2 gallon pot minimum
12-13-7-4 Tree Species Mix: When five (5) or more trees are to be planted
to meet the requirements of any portion of this ordinance, including
street trees, street buffers, parking lot landscaping and other
landscape guidelines, a mix of species shall be provided. The number
of species to be planted shall vary according to the overall number
of trees required to be planted. See the table below:
Required Number of Trees Minimum Number of Species
5-10 2
11-30 3
31-50 4
50+ 5
12-13-7-5 Plant Quality: All plant material installed pursuant to this
Ordinance shall meet or exceed the minimum federal standards as
regulated by ANSI Z60.1, American Standard for Nursery Stock.
12-13-7-6 Planting Standards: All trees, shrubs, and other plant material
shall be planted using accepted nursery standards as published by
the American Association of Nurserymen (latest edition) including
hole size, backfilling, and fertilization.
Landscape Ordinance - Final 11/28/00 Page 16
12-13-7-7 Staking: Tree staking is not required, but may be used in areas
with high winds or other situations that make staking desirable. If
trees are staked, the stakes must be removed within 12 months to
prevent damage to the tree.
12-13-7-8 Mulch: An organic mulch such as bark or soil aid shall be applied
to all planting areas for moisture retention, weed control, and
moderation of soil temperatures. Impermeable plastic weed barrier
is prohibited under the mulch, because it restricts water and oxygen
to the roots. Gravel/rock mulch is prohibited in required landscape
areas as per 4.13.B.
12-13-7-9 Curbing: All planting areas that border driveways, parking lots,
and other vehicle use areas shall be protected by curbing, wheel
stops, or other approved protective devices. Such devices shall be
a minimum of thirty (30) inches from all tree trunks to prevent cars
from damaging tree trunks.
12-13-7-10 Utilities: The following standards apply to the planting of trees
near existing utilities and to trenching for new utilities near existing
trees:
A. Overhead Utilities: Only Class I trees in the Recommended
Plant List may be planted under or within ten (10) lateral
feet of any overhead utility wires.
B. Underground Utilities: All trees shall be planted outside of
any easement that contains a City water or sewer main,
unless written approval is obtained from the City Engineer.
If any utility easement precludes trees required by this
ordinance, the width of the required buffer shall be increased
to accommodate the required trees.
C. Trenching: New underground utilities shall stay outside of
the dripline of existing trees if trenched, or be tunneled a
minimum of three (3) feet below existing grade within the
tree's dripline. The guiding principle is that no root two (2)
inches or larger shall be cut. Note: This requirement is for
placement of new utilities and does not affect the City's
ability to access existing utilities for repair and maintenance.
Landscape Ordinance - Final 11/28/00 Page 17
12-13-7-11 Erosion Control: Soil and slope stabilization shall result from the
landscape installation.
12-13-7-12 Berms: Berm slopes shall not exceed 2:1 (horizontal: vertical). 3:1
maximum slopes are recommended. Grass that requires mowing
shall not be used on slopes steeper than 3:1.
12-13-7-13 Water Efficiency: The landscape plan shall provide for water
efficient landscaping as follows:
A. Lawn Areas: Where appropriate and on sites where other
landscape options can be incorporated, large expanses of
lawn are discouraged due to its high water consumption.
B. Mulch: Mulches shall be organic and broad uses of
gravel/rock mulch are restricted as per Section 4.8. Gravel
does not retain water , reflects heat, and causes greater
stress on trees and shrubs. Organic mulch retains water for
a longer period of time for plants.
C. Irrigation: Irrigation systems shall be designed for water
efficiency as regulated by Section 5 of this Ordinance.
D. Native Plants: Native and other low -water -use plants are
encouraged. The Approved Plant List as per Section 4.1
shows the general water requirements of the trees.
12-13-8 IRRIGATION
12-13-8-1 Irrigation Required: All landscape areas regulated by this
Ordinance shall be served with an automatic underground
irrigation system. Additional requirements affecting pressurized
irrigation systems can be found in City Ordinance 9-1-28.
12-13-8-2 Performance Specifications: Three (3) copies of detailed
irrigation performance specifications shall be submitted with the
landscape plan for all Final Plats and Certificates of Zoning
Compliance. Performance specifications shall state design
requirements, materials, and construction methods. At a
minimum, the performance specifications shall address the
Landscape Ordinance - Final 11/28/00 Page 18
following requirements:
A. Required Information
Specifications for the irrigation system shall include:
1. available gallons per minute;
2. available water pressure; and
3. point of connection.

areas shall be circuited so that they are on a separate zone or
zones from those irrigating trees, shrubs, or other reduced -
water -demand areas.
F. Overspray
Sprinkler heads shall be adjusted to reduce overspray onto
impervious surfaces such as sidewalks, driveways, and parking
areas.
12-13-8-3 Irrigation Water: Use of nonpotable irrigation water is required
when determined to be available by the City Public Works
Department as regulated by City Ordinance 9-1-28. If city potable
water is used, a separate water meter is recommended so the owner
can avoid paying sewer fees for irrigation water. Potable water shall
not be used as a primary irrigation water source on non-residential
lots with more than '/2 acre of landscaping. Year round water
Landscape Ordinance - Final 11/28/00 Page 19
availability is also required by connecting to city potable water or an
on -site well as a secondary source.
12-13-8-4 Subdivision Irrigation Systems: If the irrigation system is part of
a residential, commercial, or industrial subdivision, any irrigation
pump station shall be on a common lot. Also, the irrigation system
must be owned and maintained by an irrigation district or a
Homeowners (or Business -owners) Association.
12-13-9 SIGHT TRIANGLES
12-13-9-1 Sight Triangles: The following standards shall be observed within
all sight triangles, both at controlled and uncontrolled intersections.
In all cases, Idaho Transportation Department (ITD) and Ada
County Highway District (ACHD) standards shall apply in addition
to City of Meridian standards.
12-13-9-2 Road/Road Intersections: The boundaries of a sight triangle at
the intersection of two (2) roads are defined by measuring from the
projected intersection of the roadway edge a distance of forty (40)
feet along each roadway edge and connecting the two (2) points

C. No Class III trees shall be planted within any sight triangle.
D. The maximum height of any berm or vegetative groundcover at
maturity within the sight triangle is three (3) feet.
E. No fences higher than three (3) feet are permitted in the sight
triangle.
F. No signs taller than three (3) feet are permitted in the sight triangle,
except for street/stop signs approved by the Ada County Highway
District. Special consideration for sign location can be given by the
Planning Director for lots in Old Town.
12-13-9-6 Public Safety & Enforcement: When the City determines that a
sight obstruction exists, it shall notify the owner of the property upon which the
obstruction is located and order that the obstruction be removed within thirty
(30) days. The failure of the owner to remove the obstruction shall be punishable
as a misdemeanor, and every day the owner fails to remove the obstruction shall
be a separate and distinct offense.
12-13-10 STREET BUFFERS
12-13-10-1 Purpose: Landscape buffers along streets are required in order to
improve the visual quality of the streetscape, to soften the impact
of parking lots, to unify diverse architecture, and to carry out the
Comprehensive Plan policies related to promoting attractive
roadways and street beautification.
12-13-10-2 Location: All required buffers shall be located beyond any street
right-of-way and shall be maintained by the property owner upon
which the buffer lies. All street buffers with attached sidewalks shall
Landscape Ordinance - Final 11/28/00 Page 22
be measured from the property line and not from the sidewalk or
curb. If detached sidewalks are provided as per Section 7.8, the
buffer may be measured from the back of curb when it can be
demonstrated that there is no opportunity for expansion of the
street section within the right-of-way; the buffer width must exclude
the width of the sidewalk. No fences are permitted within required
street buffers.
12-13-10-3 Applicability: Street buffers shall be required at all subdivision
boundaries (i.e. commercial, industrial, office, and residential) and
all commercial, industrial, and office developments. Single-family
residential, duplex, and townhouse lots are exempt from required
street buffers. All subdivision street buffers must be on a common
lot, maintained by a home -owners or business -owners association,
as applicable.
12-13-10-4 Buffer Size: The required width of the landscape buffer is
calculated based on the Ada County Long Range Highway and
Street Map (and future updates) as follows. Note: Residential
Collectors do not have a required street buffer.
Street Type Buffer Width
Local Roads 10 feet
(except in residential areas per 7.3)
Urban Collector
20 feet
Principal SL Minor Arterials 25 feet
(other than entryway corridors)
Entryway Corridors 35 feet
(as defined in the Comprehensive Plan)
Interstate 84
50 feet
12-13-10-5 Width Reduction: In a development where the required street
buffer width results in an otherwise unavoidable hardship to the
property, a written request for a buffer reduction may be
submitted to the Planning Director. The request must
demonstrate evidence of the hardship caused by the required
Landscape Ordinance - Final 11/28/00
Page 23
street buffer and propose a specific alternative width. In no case
shall the width be reduced to less than ten (10) percent of the
depth of the lot without a Variance, except in Old Town.
12-13-10-6 Street Trees: All required landscape street buffers shall be
planted with trees and shrubs, lawn, or other vegetative
groundcover, with a minimum density of one (1) tree per thirty-
five (35) linear feet. If this calculation results in a fraction .5 or
greater, round up to an additional tree. If the calculation results
in a fraction less than .5, round the number down.
12-13-10-7 Tree Spacing: For design flexibility, trees may be grouped
together or spaced evenly as desired. However, trees shall be
spaced no closer than 80% of the average mature width of the
trees, as demonstrated in the following examples:

Landscape Ordinance - Final 11/28/00 Page 24
12-13-10-8 Parkways and Detached Sidewalks: Detached sidewalks are
required along all arterial streets in new developments at the edge
of existing city limits. The minimum width of the parkway area
between the curb and the sidewalk is five (5) feet. Tree plantings
within parkways less than ten (10) feet wide are restricted to
Class II trees. Existing developments and infill projects may
waive the requirement for detached sidewalks to match
surrounding conditions. If detached sidewalks are provided on
local streets in residential subdivisions, the minimum sidewalk
width may be reduced to four (4) feet.
12-13-10-9 Landscaping within Right -of -Way: If the unimproved street
right-of-way is greater than thirteen (13) feet from edge of
pavement to edge of sidewalk or property line, and road widening
project is not in the Ada County Highway District (ACHD) 5-
year funded plan, developer shall maintain a ten (10) foot wide
gravel shoulder and landscape the remainder with lawn or other
vegetative groundcover. This will require a license agreement
between the property owner and ACHD.
12-13-10-10 Impervious Surfaces: Allowed impervious surfaces include
driveways, signs and walkways. Vehicle display pads and other
related impervious surfaces are prohibited in the required street
buffer.
12-13-10-11 Berms in Street Buffers: Berm design is subject to the
provisions of Section 4.12 and 6.5.1) of this ordinance.
12-13-10-12 Stormwater Detention: Stormwater swales may be
incorporated into the buffer as provided for in Section 11. Other
stormwater detention and retention facilities shall not be
permitted in the street buffer, except along I-84.
12-13-11 PARIQNG LOTS
12-13-11-1 Right -of -Way Landscaping: A landscape buffer is required
between all parking lots and adjacent streets as regulated by Section 7, Street Buffers.
Landscape Ordinance - Final 11/28/00 Page 25
12-13-11-2 Perimeter Landscaping: The following standards apply to all
interior lot lines, side or rear, adjacent to parking lots or other vehicular use areas,
including driveways:
A. Purpose
Perimeter landscaping defines parking, loading, and other vehicular use
areas and prevents two adjacent lots from becoming one large expanse of
paving. This requirement does not hinder the ability to provide vehicular
access between lots, nor does it prohibit commercial or industrial
developments with back-to-back truck docks from sharing paved loading
areas.
B. Size and Location
Provide a five (5) foot minimum perimeter landscape strip along all
interior lot lines that are adjacent to parking, loading, or other paved
vehicular use areas, including driveways, vehicle sales areas, truck
parking areas, bus parking areas, and vehicle storage areas.
C. Landscaping
The perimeter landscape strip shall be planted with one (1) tree per thirty
five (35) lineal feet and shrubs, lawn, or other vegetative groundcover.
12-13-11-3 Internal Landscaping: Interior parking lot landscaping shall be
required on any parking lot with more than twelve (12) spaces.
A. Required Percentage
The required amount of landscaping is based on a sliding scale as
follows:
Total Number
of Parking Spaces
13-100
101-200
201 +
Landscape Ordinance - Final 11/28/00
Percent of Total Area
of a Parking Lot that Must be
an Interior Landscaped Area
4 percent
6 percent
8 percent
Page 26
B. Planter Size
Landscape planters shall contain a minimum of fifty (50) square feet
and the planting area shall not be less than five (5) feet in any
dimension, measured inside curbs. The only exception to the five-
foot minimum dimension is at the tip of triangular planters located
at the end of rows of angled parking.
C. Parking Spaces
No linear grouping of parking spaces shall exceed twelve (12) in a
row, without an internal planter island.
D. Parking Lot Layout
Interior landscaping shall, insofar as possible, be used to delineate
and guide major traffic movement within the parking area so as to
prevent cross -space driving. Interior landscape planters shall be
spaced as evenly as feasible and at the ends of rows of parking
throughout the lot to consistently reduce the visual impact of long
rows of parked cars.
E. Trees Required
Each interior planter that serves a single row of parking spaces shall
be landscaped with at least one (1) tree and shall be covered with
low shrubs, lawn, or other vegetative groundcover. Each interior
planter that serves a double row of parking spaces shall have at least
two (2) trees and shall be covered with low shrubs, lawn, or other
vegetative groundcover. Deciduous shade trees must be pruned to
a minimum height of eight (8) feet above the adjacent parking areas.
Evergreen trees and Class III trees are prohibited in interior
planters.
F. Design Flexibility
In parking areas where the strict application of subsection 8.3.Awill
seriously limit the function and circulation of the lot, up to fifty
(50) percent of the required landscaping may be located near the
perimeter of the paved area to emphasize entrance corridors or
special landscape areas within the general parking area. Such
required interior landscaping which is relocated shall be in addition
to perimeter landscape and right of way screening requirements.
Landscape Ordinance - Final 11/28/00 Page 27
G. Industrial Exclusion
Industrial parking, storage, and loading areas are specifically
excluded from the interior landscape requirements, but shall still be
required to meet all perimeter and right of way landscape and
screening requirements.
12-13-11-4 Existing Parking Lot Applicability
Existing parking lots shall be required to conform to this section
based upon the following guidelines:
A. For restriping, parking lot overlays, or parking lot
replacement less than 25%, no additional landscaping shall
be required.
B. For parking lot replacement that is 25-50% of the parking
area, Perimeter and Right of Way Landscaping as required by
the Ordinance shall be installed.
C. For parking lot replacement that is greater than 50% of the
parking area, all current landscape standards of the
Ordinance shall be met.
D. If the location of existing buildings or other structures
prevents conformance with the requirements of this section,
or if its implementation would create a non -conformity with
parking standards, the Planning Director shall determine how
the Code is to be applied.
12-13-12 BUFFERS BETWEEN DIFFERENT LAND USES
12-13-12-1 Purpose: The landscape requirements in this section are
intended to ensure incompatible, adjoining land uses are
adequately protected and are provided an appropriate amount of
land separation to conduct permitted uses without causing
adverse impact. An incompatible land use is defined as one that is
more intensely developed than its neighbor (as defined herein
under section 9.4) and typically involves minimizing potential
nuisances such as noise, dirt, litter, glare of lights, or other
objectionable activities. The buffers are required along the entire
contiguous property line.
Landscape Ordinance - Final 11/28/00 Page 28
12-13-12-2 Responsibility for Buffer Construction: The required buffer
between different land uses shall be provided by the higher
intensity use and shall be located on the building site of the
higher intensity use, except as determined otherwise by the
Planning Director after written request. If a lower intensity use is
proposed adjacent to an existing higher intensity use with no
buffer, the lower intensity use must provide the required buffer.
12-13-12-3 Buffer Materials: The materials within the required buffer
between incompatible land uses are regulated as follows:
A. Mix of Materials
All buffer areas shall be comprised of, but not limited to, a
mix of evergreen and deciduous trees, shrubs, lawn, or
other vegetative groundcover. Fences, walls and berms may
also be incorporated into the buffer area.
B. Barrier Effectiveness
The required buffer area shall result in an effective barrier
within three (3) years and be maintained such that sixty
percent (60%) or more of the vertical surface is closed and
prevents the passage of vision through it. Trees may be
spaced closer as necessary to achieve this goal.
C. Buffer Walls
Where existing or proposed adjacent land uses cannot be
adequately buffered with plant material(s), the City may
require inclusion of a wall, fence, or other type of screen
that mitigates noise and/or unsightly uses. If a wall or
fence at least six (6) feet tall is provided, the planting
requirement may be reduced to at least one tree per 35
lineal feet, plus shrubs, lawn, or other vegetative
groundcover must be provided within the buffer area, in
lieu of the requirements of subsection B.
D. Chainlink Fencing
Chainlink or cyclone fencing, with or without slats, is
prohibited within required buffers between different land
uses. Chainlink may be used beyond the required buffer.
Chainlink fencing does not qualify as a screening material;
Landscape Ordinance - Final 11 /28/00 Page 29
therefore the buffer must still be landscaped as per
subsection B, even if a chainlink fence is provided.
12-13-12-4 Land Use Intensity Classifications: The table below is
intended to provide a general classification of land use intensities for
commonly proposed developments and is not a comprehensive list. If
a land use is not listed, the intensity classification shall be

Table Notes:
a) Buffer widths are shown in feet.
b) No buffer is required for blank (shaded) cells, unless an existing, adjacent
and higher intensity use has not provided a buffer. In such cases, the lower
intensity use must provide the buffer as per 9.2.
c) The buffers between land uses are required only along contiguous lot lines.
If incompatible land uses are across a public street from one another, the street
buffer requirements of Section 7 apply.
12-13-12-6 Pedestrian Access: Landscaping and screens shall not eliminate
pedestrian access from residential development to abutting
commercial districts and vice versa.
12-13-12-7 Existing Partial Buffers: If all or any part of the buffer has been
provided on the adjacent property, the proposed use must provide
only that amount of the buffer which has not been provided on
the adjacent property.
12-13-12-8 Relationship to Parking Lot Perimeter Requirements: All
buffers between different land uses may include any required
perimeter parking lot landscape strips (see Section 8.2) when
calculating the minimum width of the buffer.
Landscape Ordinance - Final 11/28/00 Page 31
12-13-12-9 Buffers along Pathways: All commercial, industrial, and office
developments shall provide a five (5) foot wide minimum buffer
adjacent to any planned pathways in the City's Comprehensive
Plan or Park System Master Plan. The buffer shall be planted
with a minimum of one (1) tree per thirty five (35) lineal feet.
12-13-13 TREE PRESERVATION
12-13-13-1 Purpose: This section is intended to preserve existing trees four
(4) inch caliper or greater from destruction during the
development process.
12-13-13-2 Site Design: Site plans shall make all feasible attempts to
accommodate existing trees four (4) inch caliper or greater within
their design.
12-13-13-3 Landscape Plan: All existing trees greater than four (4) inch
caliper shall be shown on the landscape plan as per Section 3.5.1-1.
Indicate whether each tree is to be retained or removed. Include
on the plan a description of how existing trees to be retained are
to be protected during construction as per Section 3.5.I.
12-13-13-4 Protection During Construction: Existing trees that are
retained shall be protected from damage to bark, branches, and
roots during construction. The City of Meridian Parks
Department arborist shall approve the protection fence(s) prior to
construction. Construction, excavation, or fill occurring within
the drip line of any existing tree may severely damage it. Any
severely damaged tree shall be replaced in accordance with
Subsection 10.6 of this Ordinance.
12-13-13-5 Construction within the Dripline of Existing Trees: Specific
requirements for construction within the dripline of existing trees
are as follows:
A. Paving
Whenever possible, impervious paving surfaces shall
remain outside of the dripline of existing trees. When it is
not possible, impervious surfaces shall be allowed at a
distance from the trunk of a retained tree equal to the
Landscape Ordinance - Final 11/28/00 Page 32
diameter of the tree trunk plus five (5) feet.
B. Grade Changes
Grade changes greater than six (6) inches are prohibited
within the dripline of existing trees.
C. Compaction
Most of the damage to trees caused by machinery occurs to
the root system from compaction of the soil. A simple
fence or barrier that encloses the entire area beneath the
tree canopy shall be in place prior to construction.
D. Utilities
New underground utilities to be placed within the dripline
of existing trees shall be installed as per Section 4.10.0 of
this Ordinance.
12-13-13-6 Mitigation Trees: Mitigation is required for all existing trees
four (4) inch caliper or greater that are removed from the site
with equal replacement of the total calipers lost on site. Example:
two (2) 10-inch caliper trees removed may be mitigated with four
(4) 5-inch caliper trees, five (5) 4-inch caliper trees, or seven (7)
3-inch caliper trees. Existing prohibited trees within the street
buffer or parking lot need not be mitigated for if they are
removed. Existing dead, dying, or hazard trees need not be
mitigated for if they are removed. The City of Meridian Parks
Department arborist shall certify any dead, dying, or hazard trees
prior to removal. Trees that are required to be removed by
another governmental agency having jurisdiction over the project
need not be mitigated for.
12-13-13-7 Required Landscaping: Existing trees that are retained or
relocated on site may count toward the required landscaping.
Mitigation trees are in addition to all other landscaping required
by this ordinance.
12-13-13-8 Incentives: The Planning Director may allow a reduction up to
ten percent (10%) of the required parking spaces to accommodate
existing trees. Approval of the reduction in required parking
must be obtained in writing prior to submittal of plans.
Landscape Ordinance - Final 11/28/00 Page 33

12-13-14 STORMWATER INTEGRATION
12-13-14-1 Purpose: The City encourages the incorporation of vegetated,
well -designed stormwater filtration swales into required landscape
areas where topography and hydrologic features allow. Such
integrated site designs can improve water quality and provide a
natural, effective form of flood and water pollution control.
12-13-14-2 Design Guidelines: Below are requirements for designing a
landscape area that integrates stormwater facilities. The Planning
SL Zoning and Public Works Departments should be involved in
the initial design and determining the appropriateness of any site.
A. Stormwater swales incorporated into required landscape
areas shall be vegetated with grass or other appropriate
plant materials. They shall also be designed to
accommodate the required number of trees as per this
ordinance if located in a street buffer or other required
landscape area.
B. A rock sump may be incorporated into a vegetated swale to
facilitate drainage. The rock sump inlet may not exceed
more than five (5) feet in any horizontal dimension.
Grates for sand/grease interceptors may also be
incorporated, but the inlet structures may not exceed two
(2) feet in any horizontal dimension.
C. Gravel, rock, or cobble stormwater facilities are not
permitted on the surface of required landscape areas.
Cobble may be incorporated into required landscape areas
if designed as a dry creek bed or other design feature.
D. Plant materials shall be a species that are able to withstand
the anticipated changes in soil wetness and moisture levels.
E. Organic mulch shall not be used against drainage catch
basins due to potential sediment clogging.
F. Open water ponds and holding areas with a permanent
water level are not permitted in required landscape or
Landscape Ordinance - Final 11/28/00 Page 34
,"poll 1--e
buffer areas, except along Interstate-84. However, ponds
that are aesthetically designed with special grading and
vegetative features may be approved as provided for in
Section 15, Alternative Compliance.
G. Slopes must be less than 3:1 (horizontal:vertical) for
accessibility and maintenance.
H. The stormwater facility must be designed free -draining
with no standing water within 24 hours of the completion
of a storm event.
12-13-15 MICROPATH LANDSCAPING:
12-13-15-1 Purpose: The purpose of this section is to promote trees and
other landscaping along micropaths developed within the City.
The required landscaping will provide shade and visual interest
along the micropaths.
12-13-15-2 Applicability: Whenever micropaths are developed within a
subdivision or connecting from a subdivision to another
subdivision or other destinations, the landscaping standards
within this section shall apply.
12-13-1.5-3 Planter Width: A landscape strip a minimum of five (5) feet
wide shall be provided along both sides of the path. Additional
width is encouraged to allow trees to be planted further from the
pathway and prevent root damage to the path.
12-13-15-4 Required Plants: The landscape strips shall be planted with a
minimum of one (1) deciduous tree per thirty-five (35) linear feet
and shrubs, lawn, or other vegetative ground cover.
12-13-15-5 Tree Branching Height: Trees along the pathway shall be
pruned with a clear branching height of at least eight (8) feet
above the path surface.
12-13-15-6 Shrub Height: Shrubs are limited to three (3) feet high or less
at mature size to allow for safety provisions and sight distance.
Landscape Ordinance - Final 11/28/00 Page 35
12-13-15-7 Mulch: The solitary use of mulches such as bark alone without
vegetative ground covers is prohibited. Mulch under the trees
and shrubs is required as per Section 4.8.
12-13-15-8 Prohibited Trees: No evergreen trees or Class III trees shall be
planted within the required landscape strip due to safety, sight
distance, and maintenance concerns.
12-13-15-9 Fences: Fences adjacent to a micropath landscape strip are
recommended to be "see through" as it provides better visibility
from adjacent homes or buildings. If solid fencing is used, it shall
not exceed four (4) feet in height. The developer is responsible
for the construction of the fences adjacent to all micropaths. The
fence restrictions shall be included as a note on all Final Plats
that include a micropath.
12-13-16 RESIDENTIAL SUBDIVISION OPEN SPACE
12-13-16-1 Purpose: The purpose of this section is to provide common open
space in all new residential subdivisions and multi -family
developments.
12-13-16-2 Open Space Requirement: The total land area of all common
open space shall equal or exceed five (5) percent of the gross land
area of the subdivision. This requirement shall apply to all single-
family residential subdivisions of five (5) acres or more. Multi-
family developments shall provide common open space that
equals or exceeds ten (10) percent of the gross land area of the
development.
12-13-16-3 Open Space Defined: Common open space shall mean land
area exclusive of street rights -of -way and street buffers, except for
right-of-way specifically dedicated for landscaping within a
subdivision. Street buffers wider than the required minimum
dimension may count 50% of the additional area as open space.
Stormwater detention facilities must be designed in accordance
with Section 11.2 of this Ordinance in order to count toward the
open space requirement. Open space may be active or passive in
its intended use, and must be accessible by all residents of the
Landscape Ordinance - Final 11/28/00 Page 36
subdivision.
12-13-16-4 Location: The common open spaces shall be located on a
common lot. Common open space shall be grouped contiguously
with open space from adjacent subdivisions or phases whenever
feasible.
12-13-16-5 Required Improvements & Landscaping: Common open space
shall be suitably improved for its intended use, except that
natural features such as wetlands, rock outcroppings, ponds,
creeks, etc. may be left unimproved. At a minimum, common
open space lots shall include one (1) deciduous shade tree per
eight thousand (8,000) square feet and lawn, either seed or sod.
12-13-16-6 Pathways: Pedestrian pathway linkages from the subdivision to
adjacent existing or planned trails shall be provided.
12-13-16-7 Maintenance: Land shown on the final plat as common open
space may be conveyed to the City (if the Parks Department
agrees to accept conveyance). In lieu of public dedication, it
must be conveyed to an owners association for the purpose of
owning and maintaining the common area and improvements
thereon.
12-13-17 LANDSCAPE MAINTENANCE
12-13-17-1 Purpose: All required landscaping must be maintained in a
healthy, growing condition at all times.
12-13-17-2 Responsibility: The property owner is responsible for the
maintenance of all landscaping and screening devices required by
this Ordinance.

weeding, pruning, mowing, litter removal, pest control, and
removal/repair of vandalism as needed to maintain a neat and
orderly appearance.
12-13-17-4 Topping Prohibited: It shall be unlawful to top any street tree
required by this ordinance. Topping is defined as severely cutting
Landscape Ordinance - Final 11/28/00 Page 37
back limbs to stubs within the tree's crown to such a degree as to
remove the normal canopy and disfigure the tree.
12-13-17-5 Tree Grates: Tree grates must be widened to accommodate the
growing tree trunk and prevent girdling of any trees planted in
tree wells within sidewalks or other public right of way.
12-13-17-6 Dead S& Diseased Plant Materials: Plant materials which
exhibit evidence of insect pests, disease, and/or damage shall be
appropriately treated to correct the problem. Dead plant
materials shall be replaced.
12-13-17-7 Inspections: All landscaping required by this ordinance will be
subject to periodic inspections by city officials to determine
compliance or to investigate complaints made against the
property.
12-13-17-8 Enforcement: Where any property owner to which this
ordinance applies fails to maintain the required trees,
landscaping, or screening devices, the City may issue a written
notice requiring the owner to replace any dead or dying trees or
other plant materials that were required by their approved
landscape plan or by this ordinance; repair or replace any
required screening devices that have been destroyed, removed, or
are in a state of disrepair; remove weeds; or perform any other
action necessary to comply with the requirements of this
ordinance.
12-13-17-9 Penalty: The owner shall comply with the provisions of the
written notice within sixty (60) days of issuance of the notice.
Failure of the owner to comply with the notice within the
specified time frame shall be punishable as a misdemeanor; and
every day the owner fails to comply shall be a separate and
distinct offense.
12-13-17-10 Extension: The Planning Director may grant an extension of
time beyond the required sixty (60) day period due to seasonal
or adverse weather conditions which make replanting or
replacement impractical. In no case shall the extension exceed
six (6) months.
Landscape Ordinance - Final 11/28/00 Page 38
12-13-17-11 Contract Option: If the site is not maintained as required, the
City of Meridian has the right to declare the property a nuisance
and contract maintenance at the expense of the property owner.
12-13-18 ALTERNATIVE COMPLIANCE
12-13-18-1 Purpose: The intent of this section is to encourage creative
solutions to land -use problems. The City recognizes that the
specific requirements of this landscape ordinance cannot and do
not anticipate all possible landscape situations. In addition, the
City recognizes that there may be landscape proposals which
conform to the purpose, intent, and objectives of the landscape
regulations but were not anticipated in the specific regulations.
Therefore, the Department of Planning Sz Zoning may allow for a
method of alternative compliance in the event of these situations.
12-13-18-2 Conditions: Requests for alternative compliance are allowed only
when one or more of the following conditions are met:
A. Topography, soil, vegetation, or other site conditions are
such that full compliance is impossible or impractical.
B. The site involves space limitations or an unusually shaped
lot.
C. Due to a change of use on an existing site, the required
landscape buffer is larger than can be provided.
D. Additional environmental quality improvements would
result from the alternative compliance.
E. Safety considerations make alternative compliance
desirable.
F. Other regulatory agencies or departments having
jurisdiction are requiring design standards that conflict
with the requirements of this Ordinance.
G. The proposed design includes innovative design features
based on "New Urbanism," "Neo-Traditional Design," or
Landscape Ordinance - Final 11/28/00 Page 39
other current planning topics.
H. The applicant is proposing a pond with a permanent water
level in a required landscape area.
12-13-18-3 Submittal Requirements: The following items are required to
apply for Alternative Compliance. Note: if a project is being
submitted as a Planned Development, a separate application for
Alternative Compliance is not required.
A. A written request for alternative compliance shall be
submitted to the Planning & Zoning Department prior to
submittal of the development application. The request
shall state:
(1.) The ordinance requirements that are proposed to be
modified;
(2.) The project conditions in subsection 2 which justify
the proposed alternative; and
(3.) How the proposed alternative meets or exceeds the
intent of said requirement.
B. A conceptual site plan and other information as necessary
to illustrate the proposed method of alternative
compliance.
C. An application fee as set by City Council.
12-13-18-4 Design Flexibility: The Planning Director or the Director's
designee shall have authority to vary on a case -by -case basis the
required landscaping where an alternative requirement would
address unique site conditions and allow design flexibility while
still serving the intent of the Landscape Ordinance.
12-13-18-5 Variance: If compliance with this ordinance is not possible and
there is no feasible proposal for alternative compliance which is,
in the judgement of the Planning Director, equal or better than
normal compliance, the applicant must apply for a Variance in
Landscape Ordinance - Final 11/28/00 Page 40
accordance with the provisions of section 11-18-2 of the City
Ordinance. The applicant may also appeal the decision to the
City Council by filing an appeal with the City Clerk's office.
12-13-18-6 Precedent: Alternative Compliance shall be limited to the
specific project under consideration and shall not establish
precedent for acceptance in other cases.
12-13-18-7 Timeline: The Planning Director or the Director's designee shall
respond to the applicant within 15 working days regarding
acceptance or denial of the proposed alternative.
12-13-19 CERTIFICATE OF OCCUPANCY
12-13-19-1 Issuance of Certificate of Occupancy: All required landscaping
and site features must be installed according to the approved
landscape plan prior to issuance of a final Certificate of
Occupancy. Private site improvements that are above and
beyond the requirements placed on the application do not require
completion prior to occupancy —for example a clubhouse in a
residential subdivision need not be completed prior to occupancy
of residences in the subdivision.
12-13-19-2 Extension of Time for Compliance: The Planning Director
may issue a Temporary Certificate of Occupancy for a specified
time period, not to exceed 270 days when, due to weather or
other circumstances, the landscaping or other required site
amenities cannot be completed. Whenever a Temporary
Certificate of Occupancy is issued, the following shall apply.
A. Letter of Credit or Cash Escrow
A letter of credit or cash escrow for one hundred ten
percent (110%) of the cost of installation must be filed
with the City Clerk prior to issuance of a Temporary
Certificate of Occupancy. A formal bid must accompany
the letter of credit or cash escrow. The letter of credit or
cash escrow shall be effective for a minimum of twelve (12)
months. The letter of credit or cash escrow will not be
released until all landscaping and other site amenities are
completed as shown on the approved site plan.
Landscape Ordinance - Final 11/28/00 Page 41
B. Permission to Enter Property
Any property owner wishing to make arrangements with the
City for a Temporary Certificate of Occupancy must also
allow the City to enter upon the land for the purposes of
installing the required landscaping and other site amenities
in the event that the landscaping is not in place when the
Temporary Certificate of Occupancy expires.
