Subject: Revised Landscape Plan - Denny Hecker Cadillac /Pontiac/GMC
OPH Staff
Page 1 of 1
Plan: I have reviewed the revised landscape plan for the Denny Hecker Cadillac/Pontiac /GMC project. The
plan shows a reduction in the number of thornless honeylocust and the addition of other deciduous tree
species such as: Ginkgo, and Manchurian ash around the site perimeter. Also, more trees have been added
in the SW quadrant of the site. These changes improve the plan and add more plant diversity than was in
the plan previously.
Planting Detail: It doesn't look as if the "Planting Detail" has been amended as recommended 5/30/07 to
include the practice of removing the top rungs of the wire basket, burlap and twine from B &B stock prior to
filling in the planting hole. These specifications are recommended by the International Society of
Arboriculture since experience has shown that twine can remain intact and girdle trunks, top course of wire
rungs can interfere with root growth and, if exposed, be a tripping or mowing hazard, and exposed burlap
wicks water out of the root ball and results in root death and top dieback of the tree. The instructions for
these steps should be included in the Planting Detail which accompanies the landscape plan and should also
be communicated to the landscape installation contractor.
Please contact me if you have any questions regarding this review.
Please forward my comments to the developer.
