   (b)   Every development to which this Chapter applies shall retain all existing trees eighteen (18) inches in diameter or more, unless during the Site Plan or Development Plan review process, it is determined by the Planning Commission that the retention of such trees would unreasonably burden the development; and
   (c)   No excavation or other subsurface disturbance may be undertaken within the drip line of any tree eighteen (18) inches in diameter or more, and no impervious surface (including, but not limited to, paving or buildings) may be located within twelve and one-half (12.5) feet (measured from the center of the trunk) of any tree eighteen (18) inches in diameter or more unless compliance with this Subsection would unreasonably limit reasonable use of the site, as determined by the Planning Commission.
