Re:
Grapevine Creek Sewer Trunk Main Branch I & II
Coppell, Texas
Kenko Job #9306
* Grapevine Creek Park Area, Mockingbird to Moore Road
Dear Sir:
Kenko has been notified of the concern by some of the
residents of Coppell regarding the ecosystem of the referenced
project/area, The purpose of this letter is to document some of
the "partnering" efforts by the city staff and the contractor to
minimize damage in this area,
First, it should be noted that the City Council upon
recommendation from the city staff elected to utilize the micro-
tunnelling method of construction from Station 34+00 to
Station 41+25 of the new sewer line. This was an extremely prudent
decision especially considering the close proximity of
Grapevine Creek and the high probability of ecological damage due
to open trench construction in this area.
Secondly, the contractor in the spirit of cooperation and in
the attempt of minimizing damage to the existing trees and native
plant life, opted to use smaller equipment for the construction in
this area. A 650 Komatsu backhoe and an 8250 Terex dozer was
"parked" and smaller equipment rented by the contractor in this
endeavor. It should go without sayin9 that the increased equipment
cost and reduced productivity substantially documents the
contractors desire to minimize damage.
Thirdly, it should be noted that every effort was made to save
each and every tree of substantial growth. Only when the required
construction allowed no alternative was a tree removed. Although
Kenko could have had the area cleared at no cost by wood cutters
interested in the wood, Kenko performed the work with its own
forces to eliminate unnecessary damage to remaining fauna.

The above list only begins to document the efforts by both the
City and contractor to minimize damage to the afore-mentioned
ecosystem. However, it is hoped that this will reassure the good
citizens of Coppell of the intent of both the City and the
contractor to complete the necessary construction to provide
adequate facilities for the citizens with minimal damage to the
ecology.
Sincerely,
