The minimum canopy cover required shall be as follows: <br />1. Determine ratio of impervious area (including stormwater ponds below the 100- <br />year flood elevation) to entire 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 cover <br />of a species: [(Minimum + Maximum Spread) : 412 x n x (0.65 for preferred <br />species or 0.50 for acceptable species, as identified in the Ramsey Tree Book). <br />Due to the unique nature of the COR district, flexibility with the minimum <br />planting standards may be approved if space is a limiting factor. <br />G. 9 size e,f PIGM.Ahmyrr Rinn, -orizcl trees and rhr-, -hr. gh;ill meet eF exr <br />size st . <br />C. Road frontage plantings. For every 35 feet of public road frontage, one overstory tree <br />shall be planted adjacent to the road right-of-way on private property. These plantings <br />are credited toward the minimum planting requirements for the district. <br />d. Parking lot landscaping. All parking lots are required to provide internal and/or <br />adjacent overstory tree plantings in an effort to shade parking surfaces and provide <br />visual relief. The planting schedule is established to provide an acceptable number of <br />plantings that may be planted in regular symmetrical patterns or irregular clusters or <br />groupings. Plantings are required at the following minimum schedule and are credited <br />toward the minimum planting requirements for the district: <br />1. 1 tree per every ten parking spaces. <br />2. Every overstory tree planting shall be provided with a planting area of at least <br />162 square feet (equivalent of a 9 foot x 18 foot parking stall). <br />3. Acceptable ground cover materials include sod, mulch, and other natural <br />ground cover. Landscaping rock and plastic underlayment is prohibited in <br />planting islands. <br />e. Bufferyards. Bufferyards help to achieve screening between differing uses with varied <br />intensities and impacts that are not always complementary when adjacent to one <br />another. When a bufferyard is required, the yard space and planting requirements are <br />not to be reduced for other purposes such as future parking and driveways, building <br />expansions, or other activities that are not in keeping with the purposes of buffering <br />and screening. <br />1. Bufferyards are intended to provide additional screening of businesses that are <br />adjacent to residential areas. The following table details the width of the <br />bufferyard along the common adjacent property line. An additional increase of <br />landscape plantings is required in the bufferyard. The table below outlines the <br />minimum required additional plantings, expressed as a percentage of the total <br />Page 87 of 160 <br />
