! appreciate the opportunity to meet with Tom at the site and have received your packet
for the proposed development. The site is a hidden gem and affords abundant
opportunity for environmentally sound development. Certainly, es~abllshl~ and
maintaining a tree preservation program through and following con--on are critical
elements.
! will welo;m~e tt~ opportunity ~ work with you In the development and c3tablishrnent
of a tree retention and preservation program, ! differentiat~ between retention and
preservation. Retaining a tree through constructJon IS not axiomatic to long term
preservation. ! am quite familiar with the Coppell, Texas Landscape Regulations. !
consider the regulations to be a guide for 'minimum' performance and a challenge to
Obvlously~ the tree cover on this site is extensive and to complete a survey of all trees
would be a monumental task. ! offer the following suggestions:
1. Have the property surveyed and ~[ markers for the roed, building, and parking
areas.
2. Appeal to the city to provide a tree survey ~rOugh a series of sub-samples by area,
which can be extrapolated to give a count of the trees in each particular area.
~/.~}_~: Take three (3) random thirty foot by thirty foot (30' X 30~) samples
within the proposed office and warehouse area. SurveY the trees in the areas. Then
determine the sample percent in square fee~ ~o that of~fie u,---~ce / warehouse to
whole t~ calculate the tree ~nd by species in this area.
3. The tree s~Jrvey should have species, diemeter~ and condition as a minimum.
Ordinal points of the canopy and crown to trunk raUo are clesirable for areas to be
4. The tree survey can become more finite as the processes of development move
forward, but the sample method should be s~d~iclent for the natural areas.
