(A) Landscaping standards. Mixed use, commercial, and industrial uses shall be subject to the landscaping requirements. The landscape requirements have been divided into four categories: Canopy Cover (C), Foundation Landscape (FL), Open Areas Landscape (OL), Landscape Screen (LS) and street trees.
(1) Canopy cover. The purpose of this requirement is to mitigate the effects of vehicular hardscape by establishing tree canopy cover to intercept rainfall, protect pavement from sun deterioration, reduce the heat island affect, and improve aesthetics. Vehicular hardscape area shall include all loading drives, parking lots, driveways, dropoffs and other areas covered with a hard surface intended for vehicles.
(a) Vehicle hardscape area requirements. A minimum of one large tree or two medium trees shall be provided per 360 square feet of required parking lot area green space. These trees shall be located within parking areas and not within any required perimeter landscaping area. Pervious pavements are considered 50% hardscape.
(b) Placement. Required canopy trees shall be located within the parking lot area islands (minimum width of six feet and total area of 180 square feet if designed as end island or nine feet in with if designed as continuous island between bays.
(2) Foundation landscape (FL). The purpose of this requirement is to soften and enhance building architecture, define access points, add color and seasonal interest, and to blend buildings in with the natural environment.
(a) Building perimeter landscaping requirement. At least 50% of the total building perimeter shall be sodded or landscaped with approved ground cover, low level plantings in an area of no less than six feet in width.
(3) Open areas landscape (OL). The purpose of this requirement is to provide general site beautification and high aesthetic quality with a mix of plant materials in open areas. Open areas include all areas not occupied by building or hardscape. Open areas landscaping shall meet the following requirements.
(a) Open area landscape requirements. Each development must have at least the minimum percentage open space shown in the following table.
Figure 152.373.01 Minimum Required Open Space | |||||
Minimum Open Space Requirement | |||||
B-1 | B-2 | B-3 and B-4 and Mixed Use | BP | I | |
Total development site | 30% | 30% | 20% | 30% | 20% |
(b) The open space areas must not be covered by a building or other impervious surface, and must be planted with trees, shrubs, flowers, native plant species or similar and covered with sod, landscape rock or mulch. All site areas and areas that have been disturbed during construction must be covered with sod to property lines and/or adjacent rights-of-way. Rock and mulch may be substituted for sod in landscaping planting beds. Areas used for demonstrated parking cannot be used to fulfill the open space requirement. Interior parking lot landscaping provided on site to meet requirements in § 152.145(L) counts towards this open space requirement.
(c) Planned Community Development District (PCDD) and Planned Unit Development (PUD) sites shall use the B1 Zoning District landscaping requirements; Town Center (TC) shall use the B3 Zoning District landscaping requirements; however can be modified through the Site Plan Review Process.
(d) Plant diversity. No more than 25% of any trees planted shall come from the same family and 15% of the same species. In addition the landscape plan design shall, at a minimum, provide at least three of the following required numbers of trees and shrubs in addition to any trees and shrubs required for screening in § 152.375:
1. One overstory tree per 3,000 square feet of open area.
2. One ornamental tree per 1,500 square feet of open space.
3. One evergreen tree per 3,000 square feet of open area, except on sites where security, pedestrian or traffic safety are a concern evergreens may be excluded or installed in a reduced number.
4. One deciduous or evergreen shrub per 100 square feet of open area.
(4) Street trees. (a) The purpose of this requirement is to soften and screen street corridors, define site access points, and blend site and streets in with the natural environment. Trees are required at the rate of one tree per 70 linear feet of road frontage, within the property line, where the property fronts any public road. Trees may be planted in the right-of-way if the species is listed in Table 152.373.01(A) of this Code and have a minimum trunk diameter of two inches measured six inches above grade.
