Re: Corps of Engineem, FI~ Water Rele~e
Villase Parkway Pump S~tion
~ar Mr. ~yle:
As you are aware, the Corps of Engineers is releasing flood waters from Lake
Grapevine and Lake Lewisville. Due to the combination of heavy rains and
controlled releases, Denton Creek has been at or near flood stage since mid
May. This in turn is impacting both the Village Parkway Pump Station and
Reservoir project.
The flood water release has created backwater conditions on the drainage
channel adjacent to the existing Sandy Lake Road Station. The backwater and
surchar$ed ground water elevation has made construction of the 36" off-site
supply line all but impossible. Additionally, the backwater is preventing
completion of the drainage channel on the station site.
Cajun Contractors has shut down their off-site pipelayin8 operations since mid
May (approximately 11 weeks). Crews were rescheduled to complete on-site
station pipins during the delay. Therefore, we are unable to determine the
exact time delay to the pump station due to Denton Creek; however, we estimate
that it is approximately 45 days to date.
Preload Construction Company is being delayed to the extent that water will
not be available for fillins or testing of the reservoir until the off-site
waterline is completed. We estimate the delay to the tank may exceed two (2)
months.
We will advise you of any developments regarding these projects and their
schedules as the information becomes available. We anticipate formal requests
for time extensions from both Contractors in the near future.
Sincerely,
Sanford W. C~, P.E.
