All #developments#, #enlargements# and #site alterations# on #Tier I sites# shall comply with the tree planting requirements set
forth in this Section, whether or not existing trees are removed as a result of such #development#, #enlargement# or #site
alteration#. However, the requirements set forth herein shall not apply to any #enlargement# of an existing #building#,
provided that such #enlargement# does not increase the #lot coverage# of said #building#.
On-site trees, pre-existing or newly planted, shall be provided on the #zoning lot# at the rate of one tree for each 1,000 square
feet of #lot area#, or portion thereof, or shall equal a total of 51 percent of all #tree credits# for trees originally on site, whichever
is greater.

For any existing tree of at least six-inch #caliper# that is preserved, credit for one tree shall be given for the first six inches of
#caliper# and, for each additional four inches of #caliper#, credit for an additional tree shall be given.

Single-trunk trees, newly planted to meet this requirement, shall be of at least three-inch #caliper# at the time of planting.
Multiple-trunk trees and low-branching coniferous evergreens shall be at least 10 feet in height at the time of planting. On-site
trees shall be of a species selected from Appendix B (Selection List for On-site Trees).
