Dear Mr. Shirley:
This letter is written as a follow-up to your February 21, 1995 letter and our meeting. Your
letter requested a written response by March 20th as to whether or not the City would be
interested in funding the materials and construction of the drainage culvert from S.H. 121
Bypass to Denton Creek with the construction of the S.H. 121 Bypass. This would necessitate
the completion of the construction plans by the City and the City Council appropriating the
necessary funds. It is my intention to take this to the City Council on March 28, 1995 to obtain
Council direction. The City is currently looking at what the cost would be but it is anticipated
to be in the $300,000 to $500,000 range. There are other things to he considered along with
the early construction of this drainage facility. One important item is that if the existing Dallas
water line needs to be lowered for the installation of the box culvert, that then there would need
to be extensive coordination between the City of Coppell, State and the City of Dallas.
It is my understanding that the early construction of this drainage facility offers not only a
benefit to the City of Coppell but a benefit to the State. Under the current State plans, there will
need to be not only the construction of the drainage facility beneath the bypass but also the
grading out and the construction of a concrete channel adjacent to Denton Tap Road to the
outfall at Denton Creek. I am also unsure as to whether or not there would also be some right-
of-way acquisition cost by TxDOT. Given these factors and the short time frame under which
we are working, the City of Coppell would like a commitment from TxDOT that the monies that
would have been expended on the temporary situation will be allocated to help offset the cost
by the City of Coppell if the Council chooses to participate in the construction of the drainage
facility prior to the construction of the roadway. It is my desire that the participation by TxDOT
would include all items that would be of a temporary nature including any right-of-way
acquisition costs or any design costs. At this time, the City is currently trying to evaluate what
our cost in the project would be, therefore, we need your numbers so that we can calculate the
difference and present that to City Council on March 28th. If at all possible, the City needs
your commitment and your numbers by March 17th, 1995. If it is not possible to provide the
numbers by that time, then I would like the flexibility to not take this item to Council until we
have a clear understanding of what the City's cost would be. If you are unable to meet the
March 17th time line, please let me know so that I can move this agenda item back to April
llth. To make the April l lth meeting, I need a response from TxDOT by March 31st.
Let me say that I appreciate the willingness of TxDOT to include the City in some of the
preliminary design considerations and challenges on this project so that they can be addressed
prior to the actual construction.
If you should have any questions or need any additional information please feel free to contact
me at your convenience.
Sincerely,
Kenneth M. Griffin, P.E.
Assistant City Manager/City Engineer
