Turn Lane to City Hall
December 21, 1992
During the plan review process for the Stonem I eade subd ivision (subdivision on the north side
of Parkway immediately north of City 1), the comment was made to the engineer that a left
turn lane would need to be constructed in the median of Parkway Boulevard for access to the
subdivision. When that request was made, the consultant replied that if turn lanes are required,
why was one not constructed for the driveway to City Hall. I informed the consultant that I was
unsure why the left turn lane was not constructed but that quite possibly at some time in the
future there might arise a need for the construction of that turn lane to facilitate traffic down
Parkway Boulevard.
At the December 17, 1992 Planning and Zoning Commission meeting, the consulting engineer,
Bill Anderson of Dowdey and Associates, stated that he had spoken with the developer of the
Stonemeade addition, Centex Corporation, and that they were amenable to installing the turn
lane into the City Hall parking lot for a cost of $5,000. This is less than what the turn lane
would cost, however, the developer stated he is working in the area and that his unit prices
would be substantially cheaper than what the City could eventually construct the left turn lane
for. On the surface this appears to be a very good move for the City to construct a turn lane
at this time at those prices if the general consensus is that the turn lane is warranted. My only
concern with the offer was that Bill Anderson also stated that the developer, in additional
consideration for the left turn lane, would like the City to insure that the flood study originally
submitted for the property known as the Parks of Coppell Tract IV would be honored. This
property is the property immediately north of the Coppell High School, which contains the
extension of Parkway Boulevard. The study was approved in 1989 and was modeled into our
Stormwater Management Study by Albert H. Halff and Associates as approved fill. I told Mr.
Anderson that if the City chose to pursue the option of having the left turn lane installed, then
by no means would the City expect any strings to be attached. The approval or reapproval of c
the fill for the other property would be evaluated and considered on its own merit. My opinion
is that the two issues should be strictly separate from each other. I realize that any item at or
over $5,000 takes a competitive bid process, however, if the City wishes to pursue the left turn
lane, quite possibly it could be installed for some number less than $5,000. The Engineering
staff is currently reviewing the flood study previously approved to insure that it still meets all
requirements and is an acceptable flood study and would have no damaging effects on any
development in the area.
F
In conclusion, my opinion is that if the City foresees a point in time where the left turn lane
would be necessary for City Hall, then now would be a very good time to construct it at the
reduced cost offered by Centex. Also, my opinion is that the two issues should be strictly
separated from each other and each considered on their own merit. I would be happy to discuss
these issues with you at your convenience.
