III. LANDSCAPE/SITE TREATMENT <br />Trees <br />13. Trees should be planted at an average rate of 1 per <br />30 linear feet of transition area (grouping is an option), <br />shrub beds should be designed as a staggered double <br />row, and ground cover should achieve 90% coverage in <br />3 years except for minimum (Le., 2 foot) planter beds. <br />Figures 35-37 show various options for separating uses. <br />14. Landscape design guidelines for required front, side <br />and rear perimeters are illustrated in figures 31 and 32. <br />15. Trees should generally be specimen quality, balled <br />and burlapped, and have a minimum size at planting as <br />shown below. This minimum tree size may be <br />increased based on the amount of buffering demanded, <br />prominence of location, and size necessary to realize <br />the applicant's assertion of landscape prominence <br />within five years. <br />16. An example of increasing tree size should be along <br />the street frontage when large paved areas are being <br />moderated or where dominating wall masses are being <br />softened. An example of decreasing tree size would be <br />where a stand of trees is being planted and only a few <br />specimen quality trees are needed to define the planting <br />area and provide visual planting depth. Typical <br />planting sizes are shown below: <br />, Tree Type Minimum Planting Size <br />Large stature deciduous <br />(i.e. maple, ash, oak) <br />Large stature evergreen <br />(i.e. pine or fir) <br />Small stature tree <br />(i.e. Japanese pear <br />or flowering dogwood) <br />2 1/2 inch caliper <br />8 ft. height <br />1 3/4 inch caliper <br />23 <br />41 <br />
