    (a) For purposes of this section, "tree canopy" shall include all areas of coverage by existing plant material exceeding five (5) feet in height, and the extent of planted tree canopy at maturity shall be based on the published reference text, manual of woody landscape plants, fifth edition, 1998, by Michael A. Dirr.
     
    (b) The planting or replacement of trees on a development site shall be required to the extent that, at a twenty (20) years, minimum tree canopies will be provided as follows:
     
      Minimum Tree Canopy Required
    B-1, B-2, B-3, B-4, B-5, B-6, IN-1, IN-2, I-1, I-2, I-3 10% of entire development site
    R-4, R-5 10% of entire development site
    R-3 15% of entire development site

    (c) Existing trees that are to be preserved may be included to meet all or part of the tree canopy requirements.
     
    (d) Existing trees infested with disease or structurally damaged to the extent that they pose a hazard to person or property, or to the health of other trees on site, shall not be included to meet the tree canopy requirements.
     
    (e) Tree canopy requirements do not replace, or negate full compliance with, the requirements of any other section of the landscaping ordinance. However, if planting of landscaping required by this ordinance meets or exceeds the tree canopy requirement, no further planting of trees or replacement of trees is required by this section.
     
    (f) In areas zoned B-4, central business district, B-6, riverfront business district or where the city planner determines that crime prevention through environmental design (CPTED) principles apply, the city planner, in consultation with the city’s urban forester, may allow the off-site planting of up to ninety-nine (99) percent of the required street trees, parking area screening, buffering and foundation plantings. Off-site planting areas shall be within the city limits and in such location as approved by the city planner.
     
    (g) The following shall be exempt from the tree canopy requirements.
     
    (1) Dedicated K-12 school sites.
