individual specimen trees that will be incorporated into the development. No more than
ten percent of the canopy retention requirement may be met by an individual tree that is
not included within a designated woodland area.
For developments that do not meet the minimum canopy coverage, the developer shall be
required to develop a planting plan to bring the total canopy coverage up to the minimum
requirement.
For development that removes canopy area or trees that would otherwise be used to meet
the canopy coverage retention requirement, the developer shall develop a replacement
plan. The replacement plan must designate an area at least one and two-tenths times the
removed cano,PY coverage area that shall be planted with replacement trees for those
removed. This plan shall locate additional trees either as a continuation of existing stands
of trees that are to be preserved or create new stands of trees in desirable locations such
as along roadway corridors, on the north and west perimeters of the development, in
common open areas, or adjacent to park facilities.
The following criteria shall be followed in establishing minimum canopy coverage:
4
1. When planting trees, one tree shall be deemed to provide 1,089 square feet of
required canopy coverage;

trees designated as native);
