(CD 4) Adopt Attached Appropriation Ordinance in the Amount of $96,528.00 for Increased Project Costs for the Emergency Sewer Work for
Trinity River Bank Erosion Affecting Two 90-inch Sanitary Sewer Mains
RECOMMENDATION:
It is recommended that the City Council adopt the attached appropriation ordinance adjusting receipts and appropriations in the Sewer Capital
Legacy Fund by increasing receipts and appropriations in the Emergency Sewer Erosion project (City Project No. 102939) in the amount of
$96,528.00, and by decreasing receipts and appropriations in the Unspecified project (City Project No. UNSPEC) by the same amount.
DISCUSSION:
The purpose of this Mayor & Council Communication (M&C) is to provide necessary additional funding for increased project costs for the
emergency sewer work for Trinity River stream bank erosion affecting two 90-inch diameter West Fork trunk sewer mains, identified as mains M-
280-B and M-338-B.
On June 27 - June 29, 2020, a major rain event flooded the job site for the riverbank erosion emergency repair project resulting in the destruction
of the access ramp to the edge of the river and damaging the sheet pile cutoff wall that provided temporary support for the two sewer mains. In
addition, the 90-inch sewer main closest to the river has shifted northward over time and developed cracks allowing raw sewage to flow into the
river during the rain event. Staff remediated the sewage spill as soon as it was discovered. To immediately address this situation, Circle C
Construction was engaged to repair the pipe (City Secretary Contract 54184: $1,600,000.00) and Freese and Nichols were engaged to provide
the necessary design (City Secretary Contract 54186: $200,000.00). During the course of the design work, it was confirmed that the 90-inch pipe
closest to the river was out of its original alignment, apparently pushed by shifting soils over time. Additional construction and design effort to
extend the pipe repair an additional 300 feet, including installation of a new manhole, is necessary to properly realign and reinforce the sewer main
and place it back in service. Bypass pumping operations continued and remained in place for the duration of the repair.
Due to actual field conditions, it was necessary to extend the pipe repair limit beyond the original scope which necessitated additional bypass
pumping. The additional funding requested will also allow for moving the bypass pumping pipes to the Village Creek Waste Treatment Plant.
