Discussion and consideration of amending the contract with Rady and Associates
for the design of Sandy Lake Road from MacArthur Blvd. to Denton Tap Road
in the amount of $10,000.00 and authorizing the Mayor to sign.
January 31, 1994
During the negotiations with Rady and Associates for the design of Sandy lake Road, there was
lengthy discussion concerning how to provide water service to the City of Flower Mound during
the time frame when the Flower Mound transmission line will be taken out of service to be
lowered. Several alternatives were proposed by Rady and Associates: connecting Flower Mound
into the City's water service for a period of time; connecting into the proposed 24" line in
Denton Tap Road at the east and west end and bypassing Flower Mound's 30' water line all
together; installing a booster pump to offset any deficiency in pressure heads mused by cross
connections to the City of Coppell and/or connecting into the City system and supplementing
additional demand with water from the City of Lewisville.
It was anticipated that because the City of Coppell did have a Water Master Plan performed in
1991, the City would be able to provide data on a computer diskette to Rady and Associates so
that various 'what iff' games could be played with the system. Because it understood that the
City could provide information on our water system analysis to Rady and Associates,
$10,000.00 was deducted from the basic design fee when the contract was awarded in June,
1993. Since that time, there have been numerous conversations with Wayne Ginn, the City
consultant for the Water Master Plan, concerning the need to obtain the computer data used to
generate our Water Master Plan. Mr. Ginn has searched his office and storage fac'flities and has
informed the City that he is unable to locate any computer information concerning the analysis
of the City's Water Master Plan from 1991. Because we cannot furnish information to Rady and
Associates, they axe unable to determine the best means to supply water to Flower Mound during
the period when their water transmission line will be out of service. It is important that the City
of Coppell be able to verify that there is a means to provided water to Flower Mound and that
providing the water will not cause a detrimental affect on the citizens of Coppell water usage.
Because it is important that this analysis be performed at this time and because the City of
Coppell is unable to provide information to Rady and Assoc'hates, my recommendation is that
we adjust the contract with Rady and Associates to allow them to generate the computer
information that will verify an alternative means of supplying water to Flower Mound during
the construction of Sandy Lake Road. In addition, I spoke with representatives of Rady and
Associates and it is their opinion that once the City has this water system information on
computer diskette it could be used to revisit our Water Master Plan to determine whether our
not there should be any changes made in the Water Master Plan. The Water Master Plan and
the Sewer Master Plan will both need to be revisited this spring or early summer in relationship
to the City of Coppell impact fees.
Therefore, it is my recommendation that the City Council approve the amendment to the
contract with Rady and Associates in the amount of $10,000 to perform the necessary water
system analysis to determine the proper way to provide water to Flower Mound during the
period of adjustment of the Flower Mound water transmission line. Staff will be available to
answer any questions concerning this item.

Dear Ken:
The terms of our present engineering services contract on the above r~fferenced project
calls for the City of Coppell to supply Rady & Associates, Inc. water system data used
in generating your Master Water System Plan. In our contract negotiations for scope of
services, we reduced the overall contract mount by $10,000 if the City supplied this
data on magnetic disk. It is my understanding that this information is not available and
will require us to develop and input this data into our computer program.
We therefore request $10,000 be added to our basic services contract amount to cover
this additional work. If this is in agreement with the City, please acknowledge in the
space provided below.
Yours very truly,
RADY & ASSOCIATES, INC.
