RE: Coppell Utilities in the Vicinity of the North Lake Development
Dear Mr. Taylor:
I have been requested by Clay Phillips to provide information concerning the City of
Coppell utilities in the vicinity of the proposed North Lake development, and whether or
not they have the capacity to serve that development.
Currently there is a 12" water line in the right -of -way of Belt Line Road adjacent to the
North Lake property. We updated our Water and Sewer Master Plan in 2005 and that
update showed there was no excess capacity in our water system to provide service
outside the corporate limits of the City of Coppell. As a matter of fact, the water study
showed several deficient lines in this general area. One was the connection of the 16"
water line along Dividend Drive to tie into two dead -end water lines. That line has been
completed. Another was the upgrading of an 8" line near the intersection of Airline
Drive and Belt Line Road proceeding in a northerly direction to Bethel Road from an 8"
to a 16" line. That project has been completed. The other deficiency in the area was the
upgrading of a 12" water line in Freeport Parkway from Airline Drive north to the city's
elevated storage tank from a 12" to a 20" line. That project has not been designed nor
constructed.
On the sewer side, we have an existing 12" and 15" sewer line adjacent to the North Lake
property in the Belt Line Road right -of -way. Our 2005 update showed there was no
excess capacity in that sewer line to serve properties outside the city limits of Coppell.
At the intersection of Southwestern and Belt Line and proceeding north to Bethel Road
and then easterly along Grapevine Creek, the study does show some excess capacity in
our sewer line. However, to get to that general location would require the construction of
a minimum of 10,000 feet of sewer line and potentially a lift station because of the
flatness of the area.
We recently had Freese & Nichols, Inc. perform a re- evaluation of our water and sewer
capacity in this general vicinity because of a proposed development that would be along
Dividend Drive. That study confirmed that there was very little if any capacity in our
existing water lines and that our existing sewer lines were potentially under -sized for that
proposed development within the City of Coppell.
To adequately evaluate our utility capacity and to determine what infrastructure is needed
to serve property outside the limits of the City of Coppell would require an updated,
detailed analysis of our system taking into account the proposed development that would
take place in North Lake, i.e. the proposed number of apartment units, retail, schools, or
any other type of development 'within that area. At a bare minimum, an evaluation of our
capacity to serve North Lake would probably require the construction of an additional
pump station and storage facility for water, along with numerous water lines and the
upsizing or construction of new sewer lines with the construction of a lift station.
In summary, based on all information we have available, there is no excess capacity in
the city's water or sewer systenn to provide service outside our city limits. To determine
the scope of what would be needed to provide service would require an updated, detailed
analysis of our facilities in the area taking into account the exact proposed development
in the North Lake area.
Hopefully this has answered an,y questions concerning our ability to serve the North Lake
area. If you should have any additional questions, please feel free to contact me at your
convenience.
Sincerely,
Kenneth M. Griffin, P.E.
