(Ord. 8592. Passed 7-2-24.)

1177.03 LANDSCAPING MATERIALS AND STANDARDS.

   (a)   Responsibility for Installation of Landscaping Materials. The landscaping requirements shall be provided by the person in charge of or in control of developing the property, whether as owner, lessee, tenant, occupant or otherwise.
   (b)   Existing Landscape Material.
      (1)   Unless otherwise noted, existing landscape material in healthy condition can be used to satisfy the requirements of this chapter in whole or in part provided they meet all requirements of this chapter.
      (2)   The City Engineer shall determine satisfaction of this requirement.
   (c)   Easements and Clear Vision.
      (1)   Required landscaping may be placed wholly or partially in utility or other easements provided all requirements can be fulfilled and approval is granted by the holder of the easements.
      (2)   Landscaping must also be placed in the required area between the property line and the front, rear and side yard setbacks.
      (3)   In no case shall landscaping and buffer yards be established so as to block the sight distance at street or drive intersections in accordance with Section 1173.06 Traffic Safety Visibility Triangle.
   (d)   Landscaping Materials. Existing vegetation shall be preserved as much as possible in accordance with City tree standards in the City's Tree Care and Maintenance Ordinance. The following items are suitable for landscaping materials used individually or in combination with each other, subject to review and approval by the City Engineer. Nursery stock identification tags shall not be removed from any planting prior to inspection and approval of final installation by the City.
      (1)   Walls and Fences.
         A.   When walls or fences are used to fulfill screening requirements, they shall be detailed on the plan.
         B.   Walls or fences are to be constructed of weather-proof materials. This includes pressure treating or painting of lumber if it is not redwood or cedar and using aluminum or galvanized hardware.
         C.   Chain link fences with or without wooden or synthetic slat material shall not be allowed when used to satisfy the buffer requirements of this chapter.
         D.   Walls and fences shall be designed to orient the finished side away from the subject lot so the finished side faces the adjacent lots.
      (2)   Plants.
         A.   Plant materials used in conformance with these provisions shall conform to the American Nursery and Landscape Association and shall have passed any inspection required under state regulations. Trees shall be balled and burlapped or in containers. Shrubs, vines, and ground covers can be planted as bare root as well as balled and burlapped or from containers.
         B.   The following are specific standards for landscaping materials.
            1.   Deciduous Trees. Deciduous trees shall have a minimum caliper of at least two (2) inches diameter at breast height (DBH) conforming to acceptable nursery industry procedures at the time of planting. If deciduous trees are to be used for screening purposes, additional materials listed in this chapter shall be used to create a dense buffer.
            2.   Evergreen Trees. Evergreen trees shall be a minimum of six (6) feet in height at the time of planting. Evergreen plantings when used for buffer screening shall be planted at a maximum distance of twenty (20) feet on center to provide an effective, dense screen within four (4) years of planting.
            3.   Ornamental and Understory Trees. Ornamental and understory trees shall have a minimum height of five (5) feet or a minimum caliper of at least one and one-fourth (1.25) inches DBH conforming to acceptable nursery industry procedures at the time of planting.
            4.   Shrubs and Hedges. Shrubs and hedges shall be at least twenty-four (24) inches in height at the time of planting. Unless otherwise specified in this chapter, all shrubs and hedges shall be designed to provide an effective, dense screen and mature height of at least six (6) feet within four (4) years after the date of the final approval of each planting. The height at installation of the planting shall be measured from the level of the surface of the plant base at the edge closest to the screening.
            5.   Grass and Ground Cover. Grass of the Fescus (Gramineak) or Bluegrass (Poaceae) family shall be planted in species normally grown as permanent lawns in the City of Defiance. In swales or other areas subject to erosion, solid sod, erosion reducing net, or suitable mulch shall be used and nursegrass seed shall be sown for immediate protection until complete coverage otherwise is achieved. Grass sod shall be clean and free of weeds and noxious pests or diseases. Ground cover shall be planted at a maximum spacing of one foot on center to provide seventy-five percent (75%) complete coverage after two growing seasons.
         C.   Once the minimum landscape requirements have been met, any size plant may be installed on a lot to supplement the minimum requirements.
      (3)   Species Diversity.
         A.   To curtail the spread of disease or insect infestation in a plant species, new plantings shall comply with the approved planting material list as established in the City's Tree Care and Maintenance Ordinance and with Table 1177.03-1: Species Variety Requirements.
 
TABLE 1177.03-1: SPECIES VARIETY REQUIREMENTS
NUMBER OF TREES
REQUIRED ON SITE
MAXIMUM PERCENTAGE OF TREES
THAT MAY BE A SINGLE SPECIES
1 - 19
50%
20 - 39

40 or more
25%
         B.   Required shrubs shall utilize the same species diversity requirements.
         C.   Nothing in this subsection shall be construed so as to prevent the utilization of a larger number of different species than specified above.
      (4)   Earth Mounds. Earth mounds may be used as physical barriers which block or screen a view. Differences in elevation between areas requiring screening do not constitute an earth mound. Earth mounds shall be constructed of earthen materials and shall conform to the following standards:
         A.   The maximum side slope shall be 3:1 and the design shall be reviewed by the City Engineer to ensure that proper erosion prevention and control practices have been utilized.
         B.   Mounds and earth forms shall be designed with physical variations in height and alignment throughout their length.
         C.   Landscape plant material installed on mounds and earth forms shall be arranged in an irregular pattern to accentuate the physical variation and achieve a natural appearance.
         D.   The landscape plan shall show sufficient detail, including a plan and profile of the mound or earth form, soil types and construction techniques to demonstrate compliance with the above provisions.
         E.   Mounds and earth forms shall be located and designed to minimize the disturbance to existing trees located on the site or adjacent thereto.
         F.   Adequate ground cover shall be used and maintained to prevent erosion of the earth mound.
      (5)   Grade Changes. In cases where grading is necessary that results in a parking lot lower in elevation than the surrounding area or adjacent right-of-way, the resulting embankment shall be planted with low shrubs and shade or ornamental trees. The type and variety of plantings shall be based on the steepness of the slope.
         (Ord. 8592. Passed 7-2-24.)

1177.04 LANDSCAPING AND BUFFER REQUIREMENTS FOR THE CO COLLEGE OVERLAY DISTRICT.

   (a)   All land within the CO District that is not occupied by a structure, driveway, parking area or other permanent improvement, or in the process of being improved by the construction of such permanent facilities, shall be covered with grass, trees, shrubs, flowering plants or other vegetative ground cover, and all required plantings shall be properly maintained.
   (b)   Driveway entrances, driveways, roads, sidewalks, walkways, service areas and other access ways providing entrance to nonresidential structures within the CO District shall be landscaped with a combination of groundcover, trees, shrubs or flowering plants. Grass may be used in conjunction with other plant materials but shall not be the sole or predominant landscaping material.
   (c)   At the time any lot in the CO District is improved by the construction of a new principal building, or by the substantial improvement of an existing principal building, the perimeter boundary fronting any public street shall be planted with trees appropriate to local soil and climatic conditions.
      (1)   All tree plantings required by this subsection shall be located in the front yard setback area established by the general zoning regulations applicable to the base zoning district in which the property is located.
      (2)   The total number of trees required to be planted shall be determined by the following:
         A.   One tree of a species that may reasonably be expected to attain a mature height of twenty (20) feet shall be planted for each ten (10) feet of street frontage.
         B.   For each tree planted or preserved that is of a species that may reasonably be expected to attain a mature height of more than thirty-five (35) feet, the total number of trees required shall be reduced by three.
   (d)   Property owners are encouraged to preserve mature trees when undertaking demolition or construction activities on any land within the CO District.
   (e)   A variance from the minimum tree planting requirements of this section may be granted when the location or topographic characteristics of the improved lot render it impossible to plant the number of trees required without creating a sight obstruction that would endanger the safety of motor vehicle or pedestrian traffic or the available front yard setback area affords insufficient land that is suitable for the cultivation of trees in the numbers required. A variance from the minimum tree planting requirements shall be granted upon request of the property owner when the preservation of pre-existing trees renders the planting of trees in the numbers required by this section unnecessary to the achievement of the declared purposes of the CO District.
   (f)   Any opening made in a walkway, sidewalk, drive, or other paved surface that is open to the general public for pedestrian use to accommodate cultivation of a tree shall be at least four feet square and fitted with commercially reasonable safeguards to prevent accidental injury to pedestrians entering upon the premises. Such safeguards may include, but are not limited to, the use of walkable grates to cover the tree pit or the use of masonry, wrought iron, cast iron, steel or similarly durable decorative edging of sufficient height to prevent pedestrians from approaching the tree pit.
   (g)   Buffer Requirements for the CO College Overlay District.

1177.07 INTERIOR LANDSCAPING REQUIREMENTS FOR PARKING AREAS.

   (a)   Amount of Landscaping Required.
      (1)   For all parking areas with five (5) or more parking spaces, a total of ten percent (10%) of the paved area (not including loading spaces or stacking lanes/spaces) shall be landscaped under the provisions of this section.
 
Figure 1177.07-1: Parking Lot Interior Calculations.
The required landscaping shall be located within landscaped islands. Landscaped areas that extend into parking areas from the perimeter landscaping may count toward this requirement but only that area that extended into the parking area.
 
Figure 1177.07-2: Landscaping and screening is intended to soften the appearance of large expanses of parking areas and can also provide areas for storm water management.
   
      (2)   Landscaped islands shall be developed and distributed throughout the parking lot to define 2.major circulation aisles and driving lanes; and to provide visual and climatic relief from broad expanses of pavement.
         A.   Each island shall have a minimum dimension of nine (9) feet in any horizontal direction.
         B.   Landscape islands shall be located at the end of each parking row with a minimum size of 135 square feet for single loaded parking rows, and a minimum size of 270 square feet for double loaded rows. See Figure 1177.07-1.
         C.   No more than fifteen (15) parking spaces shall be located in a continuous row without being interrupted by a landscaped island.
         D.   Island Planting Requirements.
            1.   There shall be a minimum of two (2) deciduous trees and four (4) shrubs provided for every fifteen (15) parking spaces, or fraction thereof; such trees shall be planted within the required landscaped islands.
            2.   Each individual landscape island shall include a minimum of one (1) tree and two (2) shrubs.
            3.   Additional shrubs or low, spreading plant materials may be planted within the required landscaped islands provided there is no impairment to the visibility of motorists or pedestrians.
            4.   The landscape medians/islands that separate every fourth row of parking spaces, running the full length of the parking area, shall be planted with a minimum of one tree per forty (40) lineal feet. Sidewalks and/or pedestrian paths may be incorporated into these medians.
            5.   The trees and shrubs shall be distributed throughout the parking lot islands to decrease the appearance of a single expanse of pavement and to create a canopy effect.
            6.   The area not covered by the canopy of the tree, but within an interior landscape area, shall be covered by shrubs, grass, ground cover, landscape gravel, or mulch.
      (3)   The landscaped islands shall be protected by the installation of continuous curbs or wheel stops with a height of six (6) inches, except as modified to accommodate storm water run-off.
      (4)   The landscaped islands should be designed, to the maximum extent feasible, to accommodate storm water run-off. The use of porous pavement and/or specially designed brick or block is encouraged to increase on-site water detention for plant material and ground water supplies and to reduce problems associated with run-off.
   (b)   Perimeter Landscaping Requirements. All surface vehicular use areas designed for five (5) or more parking spaces shall be screened in accordance with this subsection.
      (1)   Perimeter Adjacent to Property Line. Vehicular use areas shall maintain a minimum five (5) foot perimeter planting strip along adjacent private property lines and public rights-of-way unless the vehicular use area is adjacent to or a continuation of a vehicular use area on an adjacent property.
         A.   The minimum planting strip width may be reduced to five (5) feet through the provision of an ornamental metal fence or masonry wall constructed in accordance with the following:
            1.   The wall or fence shall have a minimum height of three (3) feet and a maximum height of six (6) feet;
            2.   A masonry wall shall have a minimum opacity of seventy-five percent (75%) of the entire wall surface along any single lot line;
            3.   The wall or fence shall be supplemented with thirty (30)-inch high evergreen shrubs planted between the fence or wall and the lot line a minimum of three (3) feet on center.
         B.   The planting strip shall contain a continuous hedge composed of a double-staggered row of evergreen shrubs with a minimum planting height of thirty (30) inches and a maximum on-center spacing of three (3) feet.
         C.   Up to twenty-five percent (25%) of the shrubs may be deciduous.
         D.   In addition to the required shrubs, the planting strip shall include canopy trees that shall be provided at a rate of two and one-half (2.5) trees per 100 lineal feet of the perimeter of the vehicular use area. Clustering or grouping of these trees is permitted.
         E.   Understory trees may be used in areas where the presence of overhead utilities prevents the use of canopy trees.
         F.   Trees may be planted in front of, behind, or within the hedge, as long as a continuous hedge is maintained.
      (2)   Building Perimeter. When a building is not abutted by a sidewalk, shrubs shall be placed around the building perimeter of the primary facade a minimum of three feet from the building. Building perimeter landscaping is not required when loading, service, or drive-through service access areas are adjacent to the building. See Figure 1177.07-3
 
Figure 1177.07-3: Building perimeter planting.
(Ord. 8592. Passed 7-2-24.)

1177.08 MAINTENANCE.
