Ken,
We are in agreement on the sewer fee issue. As far as the design goes, I agree that we want to impact the drainage as
little as possible. We are ok with the concept of moving the sewer under the sidewalk, however it appears that that is
where the gas line is. I'm a little concerned with the slope of the 8" line. Our minimum is .35%.
I have made contact with Mat Atkins at TNP. He should contact you. If he doesn't please call him at 214-461-9867. They
are easy to work with and will be happy to coordinate this interface between the two projects.
I suggest you continue moving forward on the plans, and we can talk next week about the submittal. We still have 3
property owners we are dealing with on ROW/easements, and we still have utility conflicts to resolve. The big date I am
shooting for is a contract in hand and a notice to proceed by mid May 2008. That leaves us a little time to finish the plans
and bid documents.
We will likely host another utility coordination meeting in January. The big push at that meeting will be this project, as well
as a few other fast track projects.

Keith,
I have done some digging in files related to the sanitary sewer design
issue and this is what we would like to propose. Ignore all the letters
about revising or increasing the contract fee and just leave the
contract fee alone. The original contract has $6,000 for water line
design in it and we would like to leave that number unchanged and we
will include the sanitary sewer design from Kaye Street up to
Plantation/Ruby. We think this fair due to the length of time the
project has been idle and our increased cost of doing business over the
past three years. If this is okay with you let me know.
In the mean time we are working on the sanitary sewer design as I write
this. As we have dug back into the sewer issue we have rediscovered
that the existing main is extremely shallow and there is no way to lower
the main based on existing elevations. If replaced in it's current
location, the new main will be in conflict with the proposed storm
sewer. This leaves us a couple of options that can be done. Leaving
the main in it's current location would cause us to have to lower the
storm sewer having an impact on the downstream design. We are already
going to have to increase the size of the storm sewer some because of
the additional run off from east of Coppell Road that is being added to
the system for future development and the Cooper/Kaye Street drainage
project impacting the downstream system. Another option would be to

move the sanitary sewer main to the east behind the curb and under the
proposed sidewalk to avoid the storm sewer system. I am attaching a
sketch showing you what we are talking about for you to look over and
comment on.
We have also not been able to get in contact with Teague, Nall & Perkins
to discuss the north end of the project and how to terminate our project
and not interfere with their design and construction of the
intersection. We are still trying.
As you have probably figured out, we are not finished with all of the
revisions and additions so we will not be resubmitting to you today.
Our goal is to try and get as much if not all of the changes made by the
end of next week and submit something to you on Friday, December 7. We
will continue working on the things that we can while you look the plans
over and supply you with any additional information you need. That way
we can continue moving this project towards bidding & construction.
I am sure you will have some questions, so fire away.
