When parking lots contain multiple bays of parking, parking islands shall be installed and one-third (1/3) of the
required plant material for the parking lot shall be placed within the islands. A parking island shall be a minimum
area of 130 square feet per tree and a minimum width of eight (8) feet (measured from back-of-curb to back-of curb
or edge or pavement to edge of pavement). Flat curbed islands or islands with curb cuts designed to be used as bio-
retention areas (for treating stormwater runoff) should be used, where possible.
