<br />105 <br />2. The following equation shall be used to calculate required canopy coverage: <br /> <br />Vehicular Hardscape (Square Feet) x Canopy Cover Percent = Required <br />Minimum Canopy Cover (Square Feet) <br /> <br />The total of the assigned canopy coverage values for all the trees in or near the <br />vehicular hardscape must be equal or greater than the required minimum. Pervious pavements <br />are considered 50 percent hardscape. <br /> <br />3. The assigned canopy coverage value of each tree is based on planting location, <br />tree size and anticipated tree canopy size 15 years after planting. The assigned canopy cover <br />value to each deciduous tree is described in the following table and illustrations: <br /> <br />Table 1 <br />Assigned Canopy Cover Value <br /> <br /> <br />Planting Location <br />(for new trees) <br />Interior <br />parking lot <br />islands <br />Within less <br />than 7’ of <br />vehicular <br />hardscape <br />edge <br />7’-12’ from <br />vehicular hardscape <br />edge <br />Assigned Canopy <br />Coverage Value <br /> <br />100 percent of <br />the canopy <br />square footage <br />50 percent <br />of the <br />canopy <br />square <br />footage <br />25 percent of the <br />canopy square <br />footage <br />Square <br />feet (SF) of <br />canopy <br />coverage <br />assigned to <br />each <br />deciduous <br />tree <br />Large Tree <br />950 SF (or <br />1200 SF in <br />islands of 3 or <br />more trees) <br />600 SF 300 SF <br />Medium <br />Tree 500 SF 250 SF 125 SF <br />Small Tree 250 SF 125 SF NA <br /> Existing <br />Tree: <br />6 – 12” dbh <br />1900 SF 950 SF NA <br /> Existing <br />Tree: <br />12+”dbh <br />2850 SF 1425 SF NA <br />
