development without surface parking other than individual unit driveways and pennitted exterior <br />storage areas in Industrial Districts. <br />1. The required minimum canopy coverage for all uses is 40%. <br />2. The following equation shall be used to calculate required canopy coverage: <br />Vehicular Hardscape (Square Feet) x Canopy Cover Percent = Required <br />Minimum Canopy Cover (Square Feet) <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 are <br />considered 50% hardscape. <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 />Assigned Canopy Cover Value <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 <br />hardscape <br />edge <br />Assigned Canopy <br />Coverage Value <br />100% of the <br />canopy square <br />footage <br />50% of the <br />canopy <br />square <br />footage <br />5% of the <br />canopy <br />square <br />footage <br />Square feet (SF) of <br />canopy coverage <br />assigned to each <br />deciduous tree <br />Large Tree <br />50 SF (or 1200 <br />SF in islands <br />of 3 or more <br />trees) <br />600 SF <br />300 SF <br />Medium Tree <br />500 SF <br />250 SF <br />125 SF <br />Small Tree <br />250 SF <br />125 SF <br />NA <br />Existing <br />Tree: <br />6-12"dbh <br />1900 SF <br />950 SF <br />NA <br />Existing <br />Tree: <br />12+"dbh <br />2850 SF <br />1425 SF <br />NA <br />3-32 <br />
