Projects should attempt to limit the <br />planting of any one genus to no more than 20 percent of the total plantings. <br />(7) Planting requirements for business Gnd e„^P'^y.F^e„t districts <br />Business di t.46tc /6_9'I R_7 a R_2 A/ighbe -,4eed USiReS ; Gnd u_1 The minimum number of <br />trees required are outlined in the table below. These are minimum requirements and can be <br />supplemented with other plantings, as well as flowers and various ground covers that would <br />be appropriate to produce a complete and quality landscape. <br />Planting Type <br />Required Numbers <br />Deciduous/coniferous trees <br />1 tree per 50 lineal feet of site perimeter, or 1 tree per 1,000 square <br />feet of building footprint, whichever is greater. For building <br />expansions, 1 additional tree is required for each 1,000 square feet <br />of new building footprint area. <br />Shrubs <br />1 shrub per 30 lineal feet of site perimeter or 1 shrub per 300 square <br />feet of building footprint area, whichever is greater. <br />b. Business districts. The minimum number of plantings required shall be determined based on <br />canopy cover. To fulfill the planting requirements, a combination of trees and shrubs shall <br />meet or exceed the minimum required canopy cover square footage. The minimum canopy <br />cover required shall be as follows: <br />1. Determine ratio of impervious area (including stormwater ponds below the 100-year <br />flood elevation) to entire site. <br />2. Multiply the impervious area/site area ratio by the square footage of the pervious area <br />to calculate the required canopy cover square footage for the project area. <br />3. The following formula shall be utilized to determine the average canopy cover of a <br />species: [(Minimum + Maximum Spread) : 4]2 x n x (0.65 for preferred species or 0.50 for <br />acceptable species, as identified in the Ramsey Tree Book). <br />c. Minimum size of plantings. Required trees and shrubs shall meet or exceed the following size <br />standards: <br />Plant Type <br />Size <br />Deciduous Tree <br />2.5 inch caliper <br />Coniferous Tree <br />6 feet in height <br />Ornamental/Understory Tree <br />1.5 inch caliper <br />Deciduous Shrub <br />2 feet in height <br />Coniferous Shrub <br />2 feet in height or width, based on growth characteristics <br />d. Road frontage plantings. For every 35 feet of public road frontage, one overstory tree shall <br />be planted adjacent to the road right-of-way on private property. These plantings are credited <br />toward the minimum planting requirements. <br />e. Parking lot landscaping. All parking lots are required to provide internal and/or adjacent <br />overstory tree plantings in an effort to shade parking surfaces and provide visual relief. The <br />planting schedule is established to provide an acceptable number of plantings that may be <br />planted in regular symmetrical patterns or irregular clusters or groupings. Plantings are <br />required at the following minimum schedule: <br />1. 1 tree per every ten parking spaces. <br />Page 79 of 147 <br />
