RE: Denton Creek / Villages of Coppell
Dear Mr. Tumulty:
This letter is written as a follow-up to our conversation on August 14, 1995 concerning future
reclamation plans by the City of Carrollton. It was my understanding that Carrollton is
considering a reclamation east of the Elm Fork of the Trinity River and using the area between
the Elm Fork of the Trinity River and Denton Creek to provide any mitigating valley storage
requirements.
During our conversation, I stated that the City has been experiencing erosion problem along
Denton Creek. Based on City observation and several geotechnical engineers, it appears a
portion of the cause of the eroding banks along Denton Creek is attributed to the high
fluctuations in water level. The high fluctuation in the water level is caused by the uncontrolled
release of water from both the Lewisville and Grapevine Corps of Engineer lakes. The City has
been looking at whether or not it would be possible to construct a detention/retention lake
between Denton Creek and the Elm Fork of the Trinity River to accept the water from the
release of the lakes and then release it back into Denton Creek at a more consistent rate.
We would be interested in discussing any potential lake construction between Denton Creek and
the Elm Fork of the Trinity River to see if the construction could help alleviate the ongoing
problem in the City of Coppell. The City of Coppell would appreciate being notified at such
time as the City of Carrollton begins the preliminary stages of any lake construction.
If we can provide any additional information or if you wish to discuss this further please feel
free to contact me at your convenience.
Sincerely,
Ke~eth M. Griffin, P.E.
Assistant City Manager/City Engineer
