The distance between rows is 0.866 times the spacing within the row. :t. ~ 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, and other naturally occurring features may be left undeveloped in their natural state may be counted as open space with ap~oval of the Planning Director. LANDSCAPE PIAN 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.

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 street buffers with attached sidewalks shall ~ Landscape Ordinan~e - Fina111/28/00 Page 22 w I,,! :~i t . -" ~~JI ~C) 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. Street Type Local Roads (except in residential areas per 7.3) Buffer Width 1 0 feet Urban Collector 20 feet Principal & Minor Arterials (other than entryway corridors) :i: 25 feet Efltryway Corridors (as defined in the Comprehensive Plan) 35 feet Interstate 84 50 feet 12-13- LO-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.

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. II 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.D of this ordinance. i'\~ 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 1-84. 12-13-11 PARIGNG 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. ::'1 Landscape Ordinance - Fina111/28/00 Page 25 >>m -:.~ g Q ~ 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. A. I~I Required Percentage The required amount of landscaping is based on a sliding scale as follows: Total Number of Parking Spaces 13-100 ~~lOl-200 ~ 20 1 + Percent of Total Area of a Parking Lot that Must be an Interior Landscaped Area 4 percent 6 percent 8 percent ~ :+: x IZ"~ ~ ~ Page 26 Landscape Ordinance - Fina111/28/00 ,. ... A' j~W 0- ~ ' . I ~ 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 ~ Page 27 ~ l J ~ o 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. ~.l.~ .--""7' -..::: ...:: wlo.', ::!IICI( :..-~......-..... rL =~~~1ass~r.~ ~] ~ Class II ~~ w~Class III _m~ Class IV n~ Class V ~I Single Family Multi-Family Offices Restaurants Heavy ~ .- Homes Dwellings Manufacturing Duplexes Child Care N eighbar.

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. n 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. '1 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.H. 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 3.5.1. II ~~ 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. w ~ 12-13-13-4 ,\..'11,' ~.!J 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 - Fina111/28/00 Page 32 I'. !) Q ~~ 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. :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.

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, screen undesirable views, and/or decrease noise.

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, NATURAL and other naturally occurring features may be left FEATURES: undeveloped in their natural state may be counted as open space with approval of the Planning Director. 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.

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 Forestry Unit of the Boise Parks S& Recreation Department (latest edition) is hereby adopted by this reference as the City of Meridian list of approved and prohibited plant material.

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. B. Backflow Prevention Provide an appropriate bacicflow prevention device as required by City Ordinance 9-3. C. Coverage The irrigation system shall be designed to provide 100% coverage with head to head spacing or triangular spacing as appropriate. D. Matched Precipitation Rates Sprinkler heads shall have matched precipitation rates within each control valve circuit. E. Irrigation Zones Sprinkler heads irrigating lawn or other high -water -demand 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 with a straight line.

Landscape Ordinance - Final 11/28/00 Page 21 12-13-9-5 Planting and Development Standards: A. Any trees planted within sight triangles (Class I or II) shall be pruned to a minimum height of eight (8) feet above the ground or sidewalk surface and fourteen (14) feet above the adjacent roadway surface. B. No evergreen trees shall be planted within any sight triangle. 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: Examples: 3. Utilities x+ x , e .. X J or- M415evwll 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 determined by the Planning Director based upon the nearest use listed. Class I E Class II Class III Class IV L Class V Single Family Multi -Family Offices Restaurants Heavy Homes Dwellings Manufacturing Duplexes Child Care Neighbor. Hotel/Motel Contractor Centers Comm. Yards Golf Courses Libraries Middle General Retail Processing Schools Plants Cemeteries Senior Centers High Schools Grocery Stores Recycling Parks Nurseries/Greenh Personal Parking Garages ouses Services Elementary Quasi Public Warehouses Vacant Land Schools Uses zoned: Vacant Land Clinics Storage I-L zoned: Facilities R-2 Vacant Land Indoor zoned: Manufacturing R-3 R-15 Vacant Land zoned: R-4 R-40 L-O Vacant Land zoned: R-8 C-N C-G, C-C 12-13-12-5 Minimum Buffer Widths The minimum buffer width between incompatible land uses is based on the following table: Landscape Ordinance - Final 11/28/00 Page 30 Intensit Class of Adjacent Use Intensity Class of Proposed Use I II III IV V I II 20 III 20 20 IV 25 20 20 V 35 30 25 20 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. 12-13-17-3 Maintenance Defined: Maintenance shall include watering, 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.
