Tyler, Texas (KETK) — The City of Tyler has accepted bids for the Lake Tyler dam repair.
During today's meeting, the Tyler City Council authorized City Staff to advertise for bids for the Lake Tyler Dam Repair project.
Plans and specifications for the repair of the Lake Tyler dam were orginally given to the Texas Commission on Environmental Quality Dam Safety Section for review in September of 2013.
Upon review, the TCEQ asked for revisions to the plans.
City Staff revised the plans and have provided the results of computer modeling to the TCEQ for a second review on December 16, 2013. Construction of the project cannot begin until approval is received from the TCEQ.
However, City staff can proceed with pre-qualification of cutoff wall contractors and advertising the project for bids prior to receiving TCEQ's approval.
The City staff will receive submittals of qualification packets from cutoff wall contractors until February 25 and anticipates advertising upon receiving plan approval from the TCEQ.
The Lake Tyler dam was constructed in 1948 to 1949, using the best engineering practices at the time. Due to the foundation material used in the original construction, it is believed that there has always been seepage along the downstream toe of the embankment.
During the 2010 dam inspection, Tyler Water Utilities discovered a boil (water transporting soil) in addition to the seepage. A weir was set up to measure the flor from the boil.
