Root Protection Zone. A protected area around an existing tree <br />established by offsetting the drip line 5' away from the tree center. <br />Screen. A barrier that hinders sight and, potentially, access. <br />Small Shrub. Small shrubs have a mature height of less than 3'. <br />Small shrubs are interchangeable with perennials, ornamental <br />grasses and groundcovers to fulfill landscape standards. <br />Small Tree. Understory deciduous trees with a mature height of <br />18' and under. <br />Tree. Any self supporting woody plant, growing up the earth with <br />one trunk of at least 3" dbh, or a multi -stemmed trunk system with <br />a definitely formed crown. <br />Undesirable Tree. Trees that are dead, diseased, structurally <br />weak, invasive or trees that are hazardous to people, <br />infrastructure or buildings. <br />2. Landscaping Standards. New residential platted subdivisions, mixed <br />use, commercial, institutional and industrial uses shall be subject to the <br />landscaping standards unless specifically excepted. The landscape <br />standards have been divided into five categories: Canopy Cover, <br />Foundation Landscape, Open Areas Landscape, Buffer and Screen, and <br />Boulevard Trees. Projects shall comply with the applicable requirements <br />of all five categories. <br />3. Canopy Cover Standards. The purpose of this requirement is to <br />mitigate the effects of vehicular hardscape by establishing tree canopy <br />cover to intercept rainfall, protect pavement from sun deterioration, <br />reduce the heat island affect, and improve aesthetics. Vehicular <br />hardscape areas includes loading drives, parking lots, driveways, drop- <br />offs and other areas covered with a hard surface intended for vehicles. <br />Canopy cover requirements do not apply to single family residential <br />development, nor to multi -family residential development without surface <br />parking other than individual unit driveways. <br />a. The required minimum canopy coverage for all uses is 40%. <br />b. The following equation shall be used to calculate required canopy <br />coverage: <br />Vehicular Hardscape (Square Feet) x Canopy Cover Percent = <br />Required Minimum Canopy Cover (Square Feet) <br />The total of the assigned canopy coverage values for all the trees <br />in or near the vehicular hardscape must be equal or greater than <br />the required minimum. Pervious pavements are considered 50% <br />hardscape. <br />c. The assigned canopy coverage value of each tree is based on <br />planting location, tree size and anticipated tree canopy size 15 <br />
