   A.   Purpose. The purpose of this Section is to establish meaningful standards for the design, installation, maintenance and preservation of landscaping and natural areas throughout the Village.
   B.   Applicability.
      1.   General. No permit for the construction, reconstruction, extension, repair or alteration of any building, structure or use of land and no building or land or any part of any building or land, may be occupied or used until landscaping has been provided in accordance with the requirements of this Section.
      2.   Responsibility for Compliance. The following shall comply with all requirements provided in this Section, except where noted:
   a.   All new single-family detached dwellings on an individual lot shall only comply with the provisions of 6-305.D.2 Landscape Parkways, Sections 6-305.E Landscape Plan and 6-305.F Maintenance and Preservation, where applicable. (Amd. Ord. 5126 - 9/19/16)
         b.   New residential developments;
         c.   New non-residential developments;
         d.   New mixed-use developments;
         e.   New vehicular parking areas;
         f.   Modifications to an existing building or site (see Section 6-305.B.3 Modifications);
         g.   Any project requiring a Special Use Permit, Map Amendment, or Appearance Review, as determined by the Development Services Department.
(Amd. Ord. 5312 – 7/16/18)
      3.   Modifications. An existing building or site may be renovated or repaired without providing additional landscaping except when:
         a.   An addition, alteration, or enlargement to an existing building, excluding single-family dwellings, expands the original building square footage by twenty-five percent (25%) or more, singularly or collectively.
         b.   There is a creation of, or increase in, residential units within an existing building, excluding single-family dwellings.
         c.   The restoration of any building, accessory buildings or structures or portion thereof damaged by fire, explosion, flood, casualty or other natural disaster of any kind is undertaken.
   C.   Special Conditions.
      1.   Alternate Landscape Plans. The Board of Trustees may approve preliminary landscape plans whose makeup may not meet the specified quantities stated herein, if such plans are clearly superior to what could be achieved by using those minimum standards and are consistent with the purposes of this Section, as determined by the Development Services Department. (Amd. Ord. 5221 – 9/18/17)
      2.   Additional Landscaping. The Board of Trustees may require additional landscaping or site furnishings (e.g. benches, walls, park equipment) above quantities specified herein in order to mitigate a specified problem or in order to ensure a development is consistent with the objectives of this Section and/or adopted Village policy.
      3.   Changes to Approved Landscape Plan. Minor changes to an approved landscape plan shall require approval by the Development Services Department by way of an administrative appearance review. Minor changes are acceptable where such revisions do not diminish the overall intent of the approved landscape plan. Substantial changes to an approved landscape plan shall require the re-initiation of the preliminary/final landscape plan process outlined in Section 6-305 .E.4. (Amd. Ord. 5221 – 9/18/17)
   D.   Landscape Zones.
      1.   General. Landscape zones refer to distinct areas within a particular site and the specific landscape requirements that apply therein. A project site may have up to seven (7) different landscape zones, as described in this Section, although not all sites will contain every landscape zone (e.g. some developments will not have stormwater basin landscaping), as determined by the Development Services Department. Plant material quantities shall meet or exceed the requirements detailed in this Section. (Amd. Ord. 5221 – 9/18/17; Amd. Ord. 5389 – 3/4/19)

               iii.   Small infill projects in established areas adjacent to public streets shall follow the existing pattern of rear yard screening, as determined by the Development Services Department.
               iv.   The location of plant materials and fences shall be determined by the Development Services Department.
      4.   Landscape Bufferyards.
         a.   General. Landscape bufferyards shall act as physical and visual edges between the side and rear yards of adjacent parcels. Depending on the type of required bufferyard, their intent is to either unify or separate adjoining land uses. When the intent of a bufferyard is for the unification of adjacent parcels, pedestrian and vehicular cross-access between adjacent parcels is strongly encouraged, and may be required by the Village.
            1.   Single-family residential developments adjacent to single-family residential developments are exempt from bufferyard requirements. Mixed-use developments which include single-family residential units are not exempt from bufferyard requirements.
            2.   Bufferyards may remain in the ownership of the owner of the lot, or they may be subjected to deed restrictions and subsequently conveyed to a homeowners' association, provided that any such conveyance adequately guarantees the protection and maintenance of the bufferyards for the purposes of this Section.
         b.   Requirements.
            1.   A required bufferyard is determined by cross-referencing the "proposed land use" with the appropriate "adjacent land use" as detailed in Table 6-305.D.4.b (A) – Bufferyard Land Use Types. There are only two (2) land use types: Residential and Non-Residential, as described below. Specific bufferyard requirements are detailed in Table 6-305.D.4.b (B) – Bufferyard Types. If an adjacent parcel is vacant or undeveloped, the appropriate bufferyard shall be based on the parcel’s land use category as detailed in the Village’s Comprehensive Plan. If more than one bufferyard option is available, a petitioner may decide which type of bufferyard to install.

      5.   Criteria for Approval of Landscape Plans.
         a.   Design Guidelines. The following design guidelines shall be used to evaluate proposed landscaping plans:
            1.   Landscape improvements shall serve to integrate the project to the site and surrounding context, with particular sensitivity to the natural topography, watercourses, and existing vegetation. Preservation of the existing landscape material and land forms should be taken into account, particularly where mature trees are a part of the site. Depending on the context, landscaping should either offer a visual and physical connection or separation between land uses;
            2.   Landscaping shall be designed to have a natural aesthetic while having proportion, balance, unity, variety of species, and variety of color throughout the seasons, and shall be comprised of associations of plants which have similar climate, water, soil, sun exposure and maintenance needs;
            3.   The best professional practices of the American Society of Landscape Architects, American Nursery & Landscape Association, and Illinois Green Industry Association shall be followed. In addition, guidelines proposed and referenced through the Sustainable Sites Initiative shall be utilized;
            4.   Landscaping shall provide drifts and massing of plants with varying texture, color and forms to offset the mass of a building and to provide a visual relief to the straight lines of building architecture, parking lots and other man-made features;
            5.   Landscaping shall reduce the intrusion of headlights and other glare and shall provide a safety barrier between vehicles and pedestrians. Landscape plantings shall be designed to accommodate snow removal by providing appropriate setbacks and storage space;
            6.   Landscaping should screen the view of utilities or mechanical equipment. Existing site features within a required landscape zone which do not function to meet the standards of the required landscape zone shall be screened from the view of other properties or removed, as determined during review of a site plan or landscape plan;
            7.   If landscaping is used to screen service yards, utility meters and hardware, overhead doors, mechanical equipment, dumpster enclosures, and/or other potentially unattractive places from public view, landscape materials shall be planted in a natural type configuration, be equally effective in all seasons, and comply with Section 6-308.J Screening;
            8.   Landscaping should shade seating, walking, and outdoor activity areas, shield buildings from winter wind and summer sun so as to conserve energy, and should not interfere with clear access to the sun where solar energy collection is anticipated;
            9.   Landscaping should provide a natural habitat for birds and other animal life, and should preserve existing natural vegetation and other natural features (unless prohibited by building use and other agency restrictions);
            10.   Landscapes should be designed to encourage the minimum use of water, inorganic fertilizers, herbicides, and pesticides in the development and long term maintenance of landscapes;
            11.   Irrigation systems may be required for certain landscaped areas, as determined by a landscape architect. The need for sprinkler irrigation systems shall be determined by the type of plant material and the condition/growing medium that they are installed in. All irrigation systems shall be designed to minimize the use of water;
            12.   All earth berm locations shall be reviewed by the Director of Engineering to determine how the berms shall relate to drainage and public utilities. Berms shall not exceed a maximum slope of 3:1; (Amd. Ord. 5653 - 11/1/21)
            13.   An appropriate sight triangle shall be maintained at all intersections and entryways to negate the impact of visual obstructions and shall comply with Section 6-104.E Clear Sight Triangles at Street Intersections; and
            14.   Nothing shall be planted or installed within an underground or overhead utility easement or any other easement without the consent of the Village and/or the appropriate utility.
      6.   Landscape Material Requirements.
         a.   Plant Sizes. Minimum sizes for plant materials for all projects at time of installation shall be as follows:
            1.   Evergreen or deciduous shrubs: minimum eighteen (18) to twenty-four (24) inches in height, varieties normally measured by spread shall be a minimum of twenty- four (24) inches in spread;
            2.   Deciduous shade trees: minimum two and one-half (2.5) inches caliper, balled and burlapped (B&B), measured six (6) inches above the ground, all shade trees shall have a central leader. Smaller caliper trees (e.g. 1.5") are permitted in naturalized landscape areas, or as determined by the Development Services Department; (Amd. Ord. 5312 – 7/16/18)
            3.   Ornamental trees: clump form shall be a minimum six (6) feet in height or have a minimum trunk size of two inches (2) caliper;
            4.   Evergreen trees: minimum six (6) feet in height and (B&B) when installed; and
            5.   Ornamental grasses, perennials and climbing vines shall be specified as a minimum container size of one (1) gallon unless otherwise approved by the Development Services Department.

(Amd. Ord. 5312 – 7/16/18)
         b.   Plant Diversity. Diversity among required plant material is required for both visual interest and to reduce the chance of losing a large population of plants due to disease.
            1.   Table 6-305.E.6.b (A) – Plant Diversity Requirements details the necessary maximum and minimum percentage of plant species diversity based on the total quantity of plant species per plant type. Plant types include, but are not limited to, shade trees, evergreen trees, ornamental trees, shrubs, perennials and ornamental grasses. Minor deviations from plant diversity requirements may be permitted, as determined by the Development Services Department. (Amd. Ord. 5312 – 7/16/18)
               i.   For example, if a development requires fifty (50) shade trees (i.e. plant type), no more than forty (40) percent [i.e. twenty (20) trees] nor less than ten (10) percent [i.e. five (5) trees] can be of any one (1) species, and there must be a minimum of five (5) different tree species within the fifty (50) trees selected.
            2.   Native landscaping materials shall compromise thirty percent (30%) of the total plant count for all projects, except for trees and shrubs in naturalized landscapes, which should be one hundred percent (100%) native plant material specific to the proposed area’s soil, hydrology, and ecosystem.
      3.   The overall number of trees and shrubs required for a site shall be comprised of not less than thirty percent (30%) evergreen, and seventy percent (70%) deciduous, plus or minus five percent (5%).

         c.   All other specifications shall conform to the American Nursery & Landscape Association, and “American Standard for Nursery Stock (ANSIZ60.1–2014)”, as amended, published by the American Association of Nurserymen at the time of installation, and the recommended practices of the International Society of Arboriculture. (Amd. Ord. 5221 – 9/18/17)
         d.   The Development Services Department shall be notified in writing if a plant substitution is needed due to the lack of availability during construction. The plant substitution shall have the same essential characteristics of the board approved plan species. See Section 6-305.C.3 Changes to Approved Landscape Plan.
         e.   Existing trees and vegetation within a required landscape zone which are deemed healthy based on a tree survey completed by a certified arborist may be counted toward the total plant material requirements. If existing trees and shrubs do not fully meet the standards for the type of landscape zone required, additional vegetation shall be planted.
         f.   Areas within landscape bufferyard or corridors not planted with trees or shrubs must be maintained as live landscaping. The clustering of trees and shrubs is encouraged in these areas. Only small trees, small shrubs and flowers may be planted in raised containers.
         g.   The minimum depth of topsoil applied to new residential subdivisions, commercial areas and parks shall be (6) inches. All plant material shall be planted with a minimum of six (6) inches of organic soil.
         h.   Organic mulch shall be installed under trees, shrubs, and throughout planting beds to a recommended depth of three (3) inches, in accordance with the recommended practices of the International Society of Arboriculture. Mulch should be pulled away at least four (4) inches away from the bases of trees and shrubs. Mulch should not be piled up against the trunk of a tree (i.e. “volcano mulching”) and should extend to the drip line of the tree’s branches. Colorized mulch is not permitted. (Amd. Ord. 5221 – 9/18/17)
         i.   All sod shall be clean and reasonably free of weeds, pests or diseases. Grass seed shall be in conformance with U.S. Department of Agriculture rules and regulations and applicable Illinois state seed laws. All dormant seeding will require the use of an erosion control blanket (North American Green S150 or equal).
         j.   All plant material shall be installed free of disease and in a manner than ensures the availability of sufficient soil and water to sustain healthy growth, and shall be planted in a manner which is not intrusive to utilities or pavement.
      7.   Time for Installation of Required Plantings.
         a.   All landscaping, including mulching and seeding shall be completed in accordance with the approved landscape plan and site plan prior to issuance of an occupancy permit and prior to release of any letter of credit for the site. This shall apply to all types of developments.
         b.   The Village may issue a temporary occupancy permit until June 1 of the following year if landscaping is delayed due to unusual conditions, such as drought, ice, over–saturated soil (deep mud), or inappropriate planting season for the planned species, unavailability of plant species, or other circumstances beyond the petitioner’s control. If the developer has not posted a letter of credit that includes landscaping costs for the property, the petitioner must provide the Village with a letter of credit to ensure the installation of the remaining landscape material.
         c.   All parkway trees are required to be planted by June 1 of the year following issuance of the occupancy permit for any single family home. Single-family detached dwellings shall complete all landscaping, including grass, within one year of the date of issuance of a temporary occupancy permit for that dwelling.
         d.   All bufferyard and common area landscaping for residential developments shall be completed in accordance with the approved site plan at the time that eighty percent (80%) of the development is completed or within the next planting season following occupancy, whichever comes first. If the development is built in phases, then the landscaping shall be completed as eighty percent (80%) of each phase is completed or within the next planting season following occupancy, whichever comes first.
         e.   The developer or property owner shall contact the Development Services Department for a final landscape inspection upon completion of landscape installation. The Development Services Department shall notify the developer or property owner of any deficiencies.
   F.   Maintenance and Preservation.
      1.   General Maintenance Standards.
         a.   The plantings in any landscaped area must be properly maintained in order for the landscaped area to fulfill the purposes for which it was established.
         b.   The obligation for continuous maintenance is binding on the petitioner who received landscape plan approval, to any subsequent property owner(s) or any other parties having a controlling interest in the property. (Amd. Ord. 5167 – 2/20/17)
         c.   Continuous maintenance includes, but is not limited to, the removal of weeds; mowing; trimming; edging; cultivation; reseeding; plant replacement; appropriate fertilization; spraying; control of pests, insects and rodents by nontoxic methods whenever possible; watering/irrigation and other operations necessary to assure normal plant growth. The maintenance, repair, and replacement of all landscaping materials and barriers, including refuse disposal areas, walls, fences and other amenities upon their acceptance is also included.
         d.   Continuous maintenance also includes all requirements set forth in the Village of Orland Park Code of Ordinances, Title 5, Chapter 7 “Property Maintenance Code”.
         e.   The replacement of any dead or dying plant materials or plant materials supporting less than fifty percent (50%) healthy leaf growth shall be replaced annually in compliance with the approved landscape plan.
         f.   Areas of a parcel not covered by structures or pavement shall be planted with live landscaping.
         g.   In the event that any vegetation or physical element functioning to meet the standards of this Section is severely damaged due to an unusual weather occurrence or natural catastrophe, the owner shall have one (1) year or one (1) growing season, whichever is sooner, to replace or replant.
         h.   Property owners are responsible to repair or replace any and all areas damaged by seasonal snow removal to a condition compliant with the approved landscape plan on file with the Village within (1) year or one (1) growing season of the damage, whichever is sooner.
         i.   All landscape materials shall be protected from damage by vehicles or pedestrians that could reduce the viability of the plant materials. This includes maintaining landscape materials in a natural manner that precludes shaping or over-pruning of plant materials.
         j.   A parkway shall be maintained by the adjacent property owner unless an agreement for maintenance has been reached with the Village. See Village of Orland Park Code of Ordinances Tree Management Program, Title 3, Chapter 6 for additional parkway tree maintenance requirements.
         k.   At the time a developer turns over a subdivision to a homeowners association, the developer shall be responsible for replacing all dead plant material which was planted within the prior two (2) years. If a homeowner association has been responsible for maintenance during that period for over one year, the developer shall not be responsible for replacing poorly maintained plants. Examples of poor maintenance include over pruning, excessive weeds, improper trimming, diseases from lack of attention, cracking, leaning, or other problems associated with damage from snow plowing and mowing.
      2.   Naturalized Landscaping Area Monitoring and Management Standards.  Naturalized landscaping areas need management on a regular basis after installation. Naturalized landscaping areas are most often planted as the landscape perimeter for a stormwater detention area, although not limited to just these areas. Site specific conditions influence the type and frequency of management needed. See Section 6-305.E.3.e for Letter of Credit requirements for naturalized landscape areas.
         a.   Landscape Plan. A landscape plan shall be submitted for all projects where naturalized landscaping is included. See Section 6-305.E Landscape Plan for landscape plan requirements.
         b.   Monitoring and Management Plan. A near and long-term Monitoring and Management Plan (M&M Plan) is an integral component to ensuring proper long-term management of naturalized landscapes. When required, a Monitoring and Management Plan shall be submitted with a corresponding landscape plan for Village review and approval and shall coincide with the Maintenance Plan approved with a WMO Permit.
            1.   The Village document, commonly referred to as “Monitoring and Management Plan for Naturalized Vegetation Areas and Detention Basins”, as amended, shall be used as a template for the completion of a Monitoring and Management Plan. Minor edits to this template may be made by the petitioner; however, the final text of the Monitoring and Management Plan shall be approved by the Development Services Department. The following are minimum components of a Monitoring and Management Plan:
               i.   The names, addresses, contacts, and telephone numbers of the owner(s).
               ii.   The names, addresses, contacts, and telephone numbers of the party or parties legally responsible for operations and maintenance.
               iii.   If long-term management will be provided by a public agency, the Monitoring and Management Plan is to include written documentation by the public agency that they will accept such responsibility, including associated capital expenses.
               iv.   If long-term management will be provided by a property owner, business or an association, the Monitoring and Management Plan is to include a copy of the terms to demonstrate that the agreement is recorded for all lots.
               v.   A description and/or plan drawing indicating the location of permanent access (public and private), overland flow paths, control structures, etc.
               vi.   A list and schedule indicating how and when inspections and maintenance are to be performed, including both routine and infrequent maintenance tasks.
               vii.   A list of general tasks or activities that are prohibited within the basin (e.g., dumping of yard waste or debris; replacement of approved vegetation with non–approved materials; construction or placement of structures; pesticide application, fertilizer application, mowing other than for meeting specific management goals; etc.).
               viii.   Documentation of the estimated routine and non–routine expenses and dedicated source(s) of funding for continued inspection, operation, and maintenance.
               ix.   A Homeowners Association (HOA) / Business Owners Association (BOA) shall include language in the governing documents authorizing for collection of fees for the naturalized landscape maintenance and outlining the process by which corrective actions will be taken and enforced.
               x.   Written acknowledgment that any amendment to the covenants and restrictions that alters the site beyond the original condition must have prior Village approval.
         c.   Single-Family Residential Naturalized Landscaping. Single-family residential properties that include naturalized landscaping areas that exceed twelve inches (12") in height are exempt from the letter of credit requirements detailed in 6-305.E.3.e Letter of Credit, although a Landscape Plan and an abridged Monitoring and Management Plan (M&M Plan) are still required. The following conditions apply to naturalized landscaping on single-family residential properties:
            1.   A property owner shall apply to the Development Services Department and receive a written approval of the landscape plan prior to the installation of the naturalized landscaping.
               i.   The application shall include a plat of survey and a site plan of the single-family lot drawn to scale on a sheet not less than eight and one-half inches by eleven inches (8½" × 11"), which contains: the location of property lines; location of structures, fences, existing drainage patterns, and paved areas; location of each natural landscaping area; a list by scientific and common name of species intended to be planted and maintained within each area; and the setback distance of each naturalized landscape area that will be located near any property line. Any proposed soil amendments and levels of shade and sunlight should also be included on the plan.
            2.   An M&M Plan for the near- and long-term maintenance of the naturalized landscape area shall be submitted for review and approval.
               i.   The Village document, commonly referred to as "Monitoring and Management Plan for Naturalized Vegetation Areas on Single-Family Residential Properties", as amended, shall be used as a template for the completion of a single-family residential naturalized landscape Monitoring and Management Plan. Minor edits to this template may be made by the petitioner; however, the final text of the M&M Plan shall be approved by the Development Services Department.
            3.   It shall be permitted to grow native plants that exceed twelve inches (12") in height within a natural landscaping area, including ferns, grasses, sedges, rushes, forbs, shrubs and trees, in lieu of turf grass lawn in designed and managed natural landscape areas.
            4.   Natural landscaping shall be permitted in rear or side yards only, and setback at a minimum of three (3) feet of any property line. No setback shall be required where the natural landscaping is separated from adjacent lots by fencing or continuous shrub of three (3) feet or more in height, or where the natural landscape area abuts permitted naturalized landscaping on an adjacent lot.
            5.   Naturalized landscaping may occupy a maximum of thirty percent (30%) of the total existing open space within the side or rear yards of a single-family residential property.
            6.   It is not the intent of this section to allow vegetated areas to be unmanaged, overgrown, a health hazard or a breeding ground for fauna known to create a safety or health hazard. Plant species that are defined as noxious and/or invasive by the Illinois Department of Natural Resources, Midwest Invasive Plant Network, or Illinois Invasive Species Council do not come within the protection of this section.
            7.   If the naturalized landscape installation would affect natural drainage or involve earthwork or affect capacity of neighboring retention or detention facilities, then a land development review application shall be submitted as per the provisions of Title 5 of the Village’s Land Development Code.
            8.   Upon installation of a naturalized landscape area, the site shall be inspected by a Village inspector or designee to verify compliance with the approved landscape plan and proper maintenance of the natural landscape area. After a successful inspection, the property owner will be provided with a letter from the Village certifying that the naturalized landscape has been inspected and meets the criteria of this Section. Subsequent inspections shall be performed annually by the Village or designee, or as determined by the Development Services Department.
            9.   Permission for single-family residential natural landscaping may be revoked with cause, such as failure of the owners to manage the areas or to respond to notices of creation of a nuisance or violation of the weed control ordinance. (Amd. Ord. 5857 - 12/18/23)
      3.   Tree Preservation Standards.
         a.   Purpose. The purpose of this Section is to establish high preservation standards for all public and private properties within the Village, protect the Villages natural qualities and heritage, continue its reputation as an extension of the Forest Preserves, benefit the public at large as an asset to the neighborhoods, and become a source of identity and pride to the community. In addition to these high standards, this preservation ordinance specifically strives to accomplish the following:
            1.   Prevent soil erosion and sedimentation;
            2.   Reduce storm water runoff, replenish aquifers, and eliminate the costs associated with correcting the above;
            3.   Assist in the absorption of excess carbon dioxide in the atmosphere;
            4.   Create a sound buffer to noise pollution;
            5.   Provide protection against natural elements such as the sun, wind and rain;
            6.   Provide habitat for birds, which in turn, assists in the control of insects;
            7.   Protect and increase property values; and
            8.   Conserve and enhance the Village’s environment, especially its natural setting, and to protect the habitat of its existing wildlife.
         b.   Responsibility for Compliance. The following actions require tree removal permits. No Village official, unless the tree is a safety hazard, shall issue a permit provided herein in violation of the requirements of this Section.
            1.   The removal of any heritage tree, defined as any healthy tree that is twenty-four (24) inches in diameter, or greater, measured four (4) feet from the ground, from any lot, developed or undeveloped;
            2.   The removal of any tree from a parkway;
            3.   The removal of any tree, in good or poor condition, from a conservation or tree preservation easement. Easements are legal recorded agreements tied to property most often shown on a plat of survey and/or plat of subdivision;
            4.   The removal of any tree from utility owned property or non- residential utility easement;
            5.   The removal of any tree from any property, commercial, institutional, office, industrial or multifamily residential, with an approved landscape plan. (Amd. Ord. 5221 – 9/18/17)
         c.   Fines.
            1.   Failure to obtain a tree removal permit prior to removing trees will result in a fine of $200.00 per inch of tree caliper that shall be levied against that entity primarily responsible for said tree removal. Each subsequent act of unauthorized tree removal by the same entity shall result in a fifty percent (50%) increase over the previous fine levy. This is in addition to the required tree mitigation. Trees removed without a tree removal permit must also be replaced per the replacement standards set forth in Section 6-305.F.3.f Tree Replacement Standards.
            2.   Permits for the removal, relocation or replacement of trees covered herein shall be obtained by submitting an application, on a form prescribed by the Development Services Department, pursuant to the standards set forth in this Section.
         d.   Tree Pruning.
            1.   Tree pruning, done in order to remove dead branches or to ‘limb up’ the tree is permitted without a permit. If limbed up, a tree should be pruned gradually so that an unbranched trunk of a tree is never more than one-third (1/3) the total height of the tree.
            2.   Tree topping, or the removal of the tree central leader, is not permitted on any parkway tree, heritage tree, or conservation easement tree.
            3.   No more than twenty-five percent (25%) of a single tree’s canopy shall be removed in any one (1) year.
            4.   All trees must be installed and trimmed to ensure that branches shall not obstruct the view of any street intersection and so that there shall be a clear space of eight (8) feet above the surface of the street or sidewalk.
         e.   Tree Protection.
            1.   During the development of a property, or the relocation/removal of permitted trees, the owner of the property shall be responsible for the erection of any and all barriers or protective guards necessary to protect any existing or installed vegetation from damage both during and after construction, as per the recommended practices of the International Society of Arboriculture and ANSI A300 Standards. (Amd. Ord. 5221 – 9/18/17)
            2.   Trees to be preserved during the development of the property shall be protected during construction by a fence around the drip line of each tree to prevent compaction of soil and other damage to the tree by equipment or materials. No excess topsoil, construction materials, debris, or chemicals are allowed within the protected drip line of each tree. In addition, no parking of vehicles, on-site offices, or machinery is allowed inside the protected dripline. All refueling, maintenance, lunch, break and burning areas are to be located away from all protected trees.
            3.   Wherever a change of ground grading is planned, the trees to be preserved shall be protected by a retaining wall, placed at the drip- line so as to preserve the existing grade for the roots.
            4.   Wherever a change of grading is planned, the topsoil shall be preserved for the new landscaping to be installed.
            5.   When trenching alongside existing trees is unavoidable, the trench must be one (1) foot for every one (1) inch tree caliper, as measured four (4) feet above grade, away from the base of the existing tree to be preserved, as per the recommended practices of the International Society of Arboriculture and ANSI A300 Standards. (Amd. Ord. 5221 – 9/18/17)
            6.   Construction pruning and root pruning of trees directly impacted by construction may be required for preservation of existing trees. These measures must be indicated on the tree preservation plan or the submitted application for permit.
         f.   Tree Replacement Standards.
            1.   Size. All trees that are four (4) inches in diameter, measured four (4') feet from the ground shall be replaced as detailed in Table 6-305.F.3.f.1 (A) - Native Illinois Tree Replacement Standards or Table 6-305.F.3.f.1 (B) - Non-Native Illinois Tree Replacement Standards pursuant to Village approval.

      3.   Trees with a condition rated as ‘Poor’ or ‘Dead’ on a tree survey completed by a certified arborist are also exempt from mitigation requirements.
            4.   The owner of a site with landscaping that is unhealthful (i.e. spaced too closely) may be permitted to plant replacement trees in the parkway or elsewhere in the Village, if approved by Development Services Department.
            5.   Cash in Lieu. If required mitigation trees, or any other tree required by Code, cannot be provided on the site, the petitioner shall pay cash in lieu of tree replacement in the amount of $400 for each two and one-half (2.5) inch caliper deciduous canopy tree or eight (8) foot evergreen tree to the Village’s Tree Preservation and Green Infrastructure Account. Such a fee in lieu of mitigation must be approved by the Development Services Department and can only be used when replacement on site is not possible. The quantity of trees requiring mitigation does not count towards a reduction in the quantity of trees or landscaping required by this Section.
The maximum cash in lieu amount for projects less than 10 acres in area is $50,000. The maximum cash in lieu amount for projects greater than 10 acres in area is $100,000. Any cash in lieu amount above the set maximum amount will be waived by the Village. A 10% reduction of Tree Mitigation cash in lieu amount will awarded if said fee is paid in full before or at time of final landscape plan approval.
            6.   Tree Preservation and Green Infrastructure Account. The Tree Preservation and Green Infrastructure Account shall be used to support Village-initiated tree planting and green infrastructure projects located on public property within the Village of Orland Park and shall be administered by the Development Services Department. This account shall be used only for tree preservation and green infrastructure projects approved by the Village Board.
            7.   Tree Preservation Credit. A credit of $150 per caliper inch will be applied towards a project’s tree mitigation fee for every healthy (fair to good) native tree preserved on site. Preservation credit shall be for the preservation of native Illinois trees only, or as determined by the Development Services Department. A Tree Preservation Credit shall never exceed the tree mitigation fee amount. Adherence to an Village approved Tree Preservation Plan shall be required for projects awarded tree preservation credit. A line item in the amount of the tree preservation credit will be applied to a project’s letter of credit, which will be reduced to zero after written verification from a Certified Arborist that the preserved tree(s) are still in good to fair condition at least one year after issuance of a project’s certificate of occupancy. Preservation credit shall not be applied towards any other fee other than tree mitigation fees. (Amd. Ord. 5167 – 2/20/17; Amd. Ord. 5221 – 9/18/17)
            (Amd. Ord. 5312 – 7/16/18)
         g.   Heritage Tree and Parkway Tree Removal.
            1.   All heritage trees and parkway trees shall be replaced per the replacement standards set forth in Section 6-305.F.3.f Tree Preservation Standards. The number of replacement trees may be limited by what can be reasonably accommodated within the available lot area, but any reduction in mitigation requirements must be approved by the Development Services Department.
            2.   A heritage tree that is dead or diseased may be removed without replacement if the tree is certified as dead or diseased by a certified arborist, to be retained by the homeowner, and with issuance of a tree removal permit.
            3.   A parkway tree that is dead or dying may be removed without replacement if the tree is confirmed as dead or diseased by the Development Services Department or Public Works Department and with issuance of a tree removal permit.
         h.   Procedures to Obtain a Tree Removal Permit For New Development.
            1.   Tree Mitigation Plan. Developers of any site for any use other than a single family home seeking a site plan or landscape plan approval shall submit a Tree Mitigation Plan with the petition for development. A tree mitigation plan shall include:
               i.   A tree survey showing the location, edge of dripline, species, diameter at breast height (DBH) and condition of every tree four (4) inches or larger, measured from four and a half (4.5') feet from the ground, on the property. The survey shall distinguish existing trees which are proposed to be destroyed, relocated, replaced, preserved at their present location. The Development Services Department may require that the tree survey exclude those portions of the site which it determines will not be affected by the development activity.
               ii.   A tree mitigation report that highlights the quantity, diameter at breast height (DBH) and condition of trees to be removed and the quantity and caliper size of the required replacement trees pursuant to the replacement standards set forth in Section 6-305.F.3.f Tree Replacement Standards.
            2.   A tree survey and tree mitigation report, collectively known as a Tree Mitigation Plan, will be reviewed and approved by the Development Services Department through the landscape plan review process. Approval of a Tree Mitigation Plan shall be granted only if the Development Services Department finds that all reasonable efforts have been undertaken in the architectural layout and design of the proposed development to preserve existing trees and to otherwise enhance the aesthetic appearance of the development by the incorporation of trees in the design process. Relocation or replacement of trees may be required as a condition of approval in accordance with the criteria set forth in this Section. No tree removal shall take place until a Tree Mitigation Plan has been approved by the Development Services Department. (Amd. Ord. 5221 – 9/18/17)
         i.   Procedures to Obtain a Tree Removal Permit For Single Family Homes and Existing Development.
            1.   All others requesting a tree removal permit shall fill out a tree removal permit application prescribed by the Development Services Department prior to its removal or relocation. The applicant shall provide the following information:
               i.   Information on the type of tree and the size of the tree under consideration;
               ii.   Reason(s) for the tree(s) removal/relocation;
               iii.   Photograph(s) of the condition and location of the tree in question;
               iv.   At least one full scale photo of the tree(s) showing its surrounding environment. Any photographs supporting the reason(s) for relocation/removal should be included;
               v.   A copy of the plat of survey for the property showing the location of the existing building(s) and outlining the location of the existing tree(s) in question. If the tree location/removal involves existing or proposed utilities, driveways, structures, easements or other pertinent site features, these should also be drawn in to scale. Plans may be drawn by property owners; and
               vi.   A description of the tree(s) to be planted to replace any removed trees.
            2.   Approval of a tree removal permit shall be granted only if the Development Services Department finds that all reasonable efforts have been undertaken in the architectural layout and design of the proposed development to preserve existing trees and to otherwise enhance the aesthetic appearance of the development by the incorporation of trees in the design process. Relocation or replacement of trees may be required as a condition of approval in accordance with the criteria set forth in this Section. No tree removal shall take place until the issuance of a tree removal permit.
            3.   If the Development Services Department determines that the scope of the tree removal exceeds the provisions of this Section, the applicant must supply the information listed in Section 6-305.F.3.h Procedures to Obtain a Tree Removal Permit for New Development.
         j.   Final Inspection.
            1.   No final certificate of occupancy or letter of credit release shall be issued until the relocation or replacement of trees, or payment of any outstanding tree mitigation fees, as required by the approved mitigation plan or tree removal permit, has been completed and the final landscape inspection approval has been given by the Development Services Department. Trees relocated from one portion of the site to another which do not survive transplanting shall be replaced with a suitable replacement tree as specified by the Development Services Department. Should the Department determine that, due to the time of the year that the certificate of compliance and occupancy is requested, the relocation or replacement of trees should be deferred until a more suitable time, a certificate of compliance and occupancy may be issued provided that:
               i.   The letter of credit is renewed in an amount to cover the remaining landscaping to be installed.
               ii.   If a project does not have a letter of credit with the Village, the applicant(s) provides the Development Services Department with a cash deposit or bond in the amount equal to the cost of the relocation or replacement of trees;
               iii.   The applicant completes all required tree relocation or replacement within the time frame specified by the Development Services Department. The cash deposit or bond will be returned to the applicant provided that all work is completed within the established time frame. (Amd. Ord. 5221 – 9/18/17)
            2.   Should the applicant fail to comply with the above item, the Development Services Department may elect to use the cash bond or letter of credit to hire a landscaper to complete the required tree relocation or replacement. Excess cash deposit, letter of credit or bond funds, if any, will then be returned to the applicant.
         k.   Exceptions.
            1.   In the event that any tree shall pose a threat to one’s health, safety or property and require immediate removal without formal Village approval (e.g. a tree which has been blown over or struck by lightning), verbal authorization may be given by the Development Services Department and the tree removed without obtaining a written permit as herein required. Such verbal authorization shall later be confirmed in writing by the Department.
            2.   All state approved and governmental plant or tree nurseries and botanical gardens shall be exempt from the terms and provisions of this Section, but only in relation to those trees which are planted and grown for the sale or intended sale to the general public in the ordinary course of business or for some public purpose.
            3.   A tree removal authorization may be issued when a tree, due to natural circumstances, is dead or irreversibly declining, is in danger of falling, is too close to existing structures so as to endanger such structures, interferes with utility services, creates unsafe vision clearance, or constitutes a health hazard. Such trees may be removed only after the Development Services Department or Public Works Department has verified that such a condition exists.
            4.   A tree removal authorization may be issued when a tree removal is necessary to observe good forestry practice such as the number of healthy trees a given parcel of land will support or when such removal is in accordance with a documented landscape management plan.
         l.   Civil Remedies. In addition to any other remedies provided by this Section the Village shall have the following judicial remedies available for violations of this Section or any permit condition promulgated under this Section.
            1.   The Village may institute a civil action in a court of competent jurisdiction to establish liability and to recover damages for any injury caused by the removal of trees in contravention of the terms of this Section.
            2.   The Village may institute a civil action in a court of competent jurisdiction to seek injunctive relief to enforce compliance with this Section to enjoin any violation hereof; and to seek injunctive relief to prevent irreparable injury to the trees and/or properties encompassed by the terms of this Section.
