Dear Ken:
This letter is to summarize my understanding of the meeting held on Ju~e 13, 1996 which
addressed the potential environmental restoration project for Denton Creek. The restoration project
is being proposed by the City of Coppell in conjunction with the Corps of Engineers. We understand
that the initial concept for this project would direct high flows for Denton Creek into a wetland area
to be constructed north of the Weaver Tract then through the Weaver Tract and eventually into the
Elm Fork Trinity River.
The Weaver Tract (314 acre tract) was purchased several years ago by Carrollton in
anticipation of several future projects. The current plan for this tract is to create an area which will
provide replacement of valley storage and wetlands for several projects of public interest. These
projects include construction of Luna Road, construction of the future S.H. 190/161 Connector
Highway and a future reclamation area along I.H. 35E from Belt Line Road to Trinity Mills Road.
Our consulting engineer has completed initial coordination meetings with the Corps of
Engineers related to the Weaver Tract. We are ready to begin the initial design work for this tract.
Carrollton is not opposed to the concept of the Denton Creek restoration project provided that it
does not conflict with the plan for using the Weaver Tract for valley storage replacement. Based on
our meeting, there were three issues which need to be addressed by the City of Coppell and/or the
Corps of Engineers as a part of the restoration project. These issues are as follows:
Need to insure that the restoration project and the associated flow do not increase the
discharge requirements from the Weaver Tract for water volume to be evacuated
following flood events.
Control potential erosion along the northern project boundary and pond slopes during

flood events.
c. Define the frequency and timing of flow into the Weaver Tract. lnmre that overflows
do not fill available storage prematurely.
The City of Carrollton will cooperate with this project as long as these concerns are addressed
and the use of the Weaver Tract as a valley storage replacement site is not endangered.
If you have any questions about the comments within this letter, please feel free to call me.
Sincerely,
