These are minimum requirements and can be <br /> 8 supplemented with other plantings, as well as flowers and various ground covers that would <br /> 9 be appropriate to produce a complete and quality landscape. <br /> 10 <br /> Planting Type Required Numbers <br /> Deciduous/coniferous trees 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 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 /> 11 <br /> 12 b. Business districts. The minimum number of plantings required shall be determined based on <br /> 13 canopy cover. To fulfill the planting requirements, a combination of trees and shrubs shall <br /> 14 meet or exceed the minimum required canopy cover square footage. The minimum canopy <br /> 15 cover required shall be as follows: <br /> 16 1. Determine ratio of impervious area (including stormwater ponds below the 100-year <br /> 17 flood elevation)to entire site. <br /> 18 2. Multiply the impervious area/site area ratio by the square footage of the pervious area <br /> 19 to calculate the required canopy cover square footage for the project area. <br /> 20 3. The following formula shall be utilized to determine the average canopy cover of a <br /> 21 species: [(Minimum+ Maximum Spread):4]2 x n x (0.65 for preferred species or 0.50 for <br /> 22 acceptable species, as identified in the Ramsey Tree Book). <br /> 23 c. Minimum size of plantings. Required trees and shrubs shall meet or exceed the following size <br /> 24 standards: <br /> Plant Type Size <br /> Deciduous Tree 2.5 inch caliper <br /> Coniferous Tree 6 feet in height <br /> Ornamental/Understory Tree 1.5 inch caliper <br /> Deciduous Shrub 2 feet in height <br /> Coniferous Shrub 2 feet in height or width, based on growth characteristics <br /> 25 <br /> 26 d. Road frontage plantings. For every 35 feet of public road frontage, one overstory tree shall <br /> 27 be planted adjacent to the road right-of-way on private property.These plantings are credited <br /> 28 toward the minimum planting requirements. <br /> 29 e. Parking lot landscaping. All parking lots are required to provide internal and/or adjacent <br /> 30 overstory tree plantings in an effort to shade parking surfaces and provide visual relief. The <br /> 31 planting schedule is established to provide an acceptable number of plantings that may be <br /> 32 planted in regular symmetrical patterns or irregular clusters or groupings. Plantings are <br /> 33 required at the following minimum schedule: <br /> 34 1. 1 tree per every ten parking spaces. <br /> Page 79 of 147 <br />
