Planting Type Required Numbers <br />Deciduous/coniferous trees 1 tree per 50 lineal feet of site perimeter, or 1 <br />tree per 1,000 square feet of building footprint, <br />whichever is greater. For building expansions, <br />1 additional tree is required for each 1,000 <br />square feet of new building footprint area. <br />Shrubs 1 shrub per 30 lineal feet of site perimeter or 1 <br />shrub per 300 square feet of building footprint <br />area, whichever is greater. <br />b. Employment Districts (E-1, E-2, and E-3). The minimum number of plantings <br />required shall be determined based on canopy cover. To fulfill the planting <br />requirements, a combination of trees and shrubs shall meet or exceed the <br />minimum required canopy cover square footage. The minimum canopy cover <br />required shall be as follows: <br />1. Determine ratio of impervious area (including stormwater ponds) to entire <br />site. <br />2. Multiply the impervious area/site area ratio by the square footage of the <br />pervious area to calculate the required canopy cover square footage for the <br />project area. <br />3. The following formula shall be utilized to determine the average canopy <br />2 <br />cover of a species: \[(Minimum + Maximum Spread) ÷ 4\] <br />preferred species or 0.50 for acceptable species, as identified in the Ramsey <br />Tree Book). <br />c. Minimum size of plantings. Required trees and shrubs shall meet or exceed the <br />following size standards: <br /> <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 />d. Road frontage plantings. For every 35 feet of public road frontage, one <br />overstory tree shall be planted adjacent to the road right-of-way on private <br />property. These plantings are credited toward the minimum planting <br />requirements. <br />e. Parking lot landscaping. All parking lots are required to provide internal <br />overstory tree plantings in an effort to shade parking surfaces and provide visual <br />relief. The planting schedule is established to provide an acceptable number of <br />plantings that may be planted in regular symmetrical patterns or irregular <br />clusters or groupings. Plantings are required at the following minimum <br />schedule: <br />1. 1 tree per every ten parking spaces. <br /> <br />
