CMUS HARDER, WATER DIRECTOR SUBJECT: TRINITY RIVER STRE_AMBANIC EROSION AFFECTNG TWO 90" SANITARY SEWER LINES — EIMERGENCY RESPONSE Two 90" diameter sanitary sewer lines (West Pork sewer' lines) were installed in the 1960's and 1970's that initially connected -the old Riverside Plant with the Village Creek Plant. They are generally aligned parallel to and offset from the Trinity River. These two pipelines currently convey the•majority of the wastewater generated in Fort Worth to the Village Creep Plant, with flow capacity of upwards of200-million gallons per day. In the spring of 2016, Trinity River streambank erosion was discovered that threatened to expose and potentially undermine the West Fork sewer lines. An emergency contract was authorized in June of 2016 (CS No. 47913, see also, .Rine. 7, 2016 Emergency Memo) for the installation of two sheet pile.cutoff -.walls; .a -temporary solution designed to help protect the pipelines while a permanent .solution. iv ..: signed. and permitted by the U.S.' Army Corps of Engineers. - The emergency -work -vas compIcted in July 2016. The City engaged dames'Deotte Engineering, Inc. (M&C C-27950) to develop, design and permit a permanent _solution to the erosion problem. The approved design is to install a reinforced concrete wall -supported by drilled shaft piers that would act as the foundation for a rock gabion basket reinforced channel slope. The drilled piers would be extended into bedrock to provide permanent stability. The rock gabion basket would be extended from the concrete foundation up the channel bank side slope to prevent erosion. The Corps of Engineers=permit for this permanent solution was obtained in the summer of 2017. Bids for the construction of the permanent solution were obtained in late July of that year and -on September 26, 2017 (M&C C 20407) council authorized execution of a construction contract with Humphrey and-Mortorrin.the amount of $1,567,535 to construct the permanent solution. Construction -of the drilled piers was delayed almost a year, however, in part due to final easement acquisition and the discovery of artifacts in the work zone that required mitigation. Once the drilledpier construction began in late summer of 20180, it was discovered that the rock layer encountered at several locations was deeper than what was logged in the geotechnical bores taken as part of the design. Unfortunately, the engineering design needed to be revised to provide additional depth to the drilled piers to strengthen the foundation and additional vertical tie -back reinforcing of the proposed protective wall. That redesign has just recently been completed and provided to the contractor for a cost assessment. On September 22, 2010, Fort Worth was hit by a severe storm which eroded significant portions of the Trinity River and resulted in the failure of one of the sheet pile cutoff walls, The second cutoff wall is now unstable and needs to be reinforced inunediately (see attached pictures). On October 13,-2010, another storm increased the Trinity River water surface elevation at least 13' in -the impacted area, resulting in additional erosion of the streambank. Rain has occui7ed every day from October 13fl' up to the date of this memo and significant rain is forecast for the next several weeks. With the construction of the permanent solution gabion wall project expected to take six months, preparation and placement of materials and equipment necessary to perform bypass. pumping should the transmission pipes be compromised is necessary to protect public health. Under this emergency mmorandinn the Water Department intends to do the following: 1. Reinforce and repair the existing sheet pile cutoff walls and prevent farther failure (installation of driven piles with tieback rods to support). It is anticipated work will be performed by Shin and Gregory and Circle C Construction, the construction team that performed the original emergency work, at an estimated cost of $200,000. 2. Expose the 'West Fork sewer lines at points upstream and downstream of the compromised area in order to allow expedited bypass pumping. It is anticipated this work will be performed by Circle C Construction at an estimated cost of $50,000. 3. Install approximately 3,000 linear feet of 24" HDPE piping, to be in place should emergency bypass ptunping be required. Mork is anticipated to be performed by Circle C Construction. Estimated cost of $250,000. 4. Purchase two 90" sewer plugs and position them at the site for the duration of the project. These plugs will be needed in the event of damage to the existing pipes that requires bypass pumping. It is anticipated that these plugs will be purchased from Sunbelt Rentals at a cost of approximately $60,000. 5. Rent bypass pumps and purnp manifold. Costs vary based on duration of rental. Should the rental last several months, total cost would be approximately $300,000. It is anticipated that Sunbelt Rentals will be utilized for pump and manifold rentals. 6. Execute an emergency contract with Humphrey and Morton to immediately proceed with installation of vertical tiebacks and extra depth piers as regbired by the revised rock ledge information described above. Estimated cost for this additional work is W0,000 Waiting to prepare a change order to the contract under which the permanent solution is being constructed for the' additional piers and tie -back structures is not .prudent given the saturated conditions and forecast for more heavy rain. The City is exempt from competitive bidding when an emergency threatens the preservation of the city's property or the public health of the citizens: Concurrently awarding emergency contracts to repair the failing cutoff walls and establish procedures for bypass pumping, should there be a failure'of the pipeline, furthers the interest of protecting the public health and safety of the City as well as being necessary to protect 'the city's property. Chapter 2, Article 1, Section_ 2-9 at (9) of the City's Code of Ordinances and Section 252.092 of the Local Government Code exempts from nonna] bidding requirements expenditures that are necessary to preserve or protect the city's property and the public health or safety of the nrruricipality's residents. This memo is submitted to request authorization for emergency procurement of services outlined above, at a total cost of approximately $1,510,000. Mhile this cost is extremely high, the consequences of one or both of the 90" pipes failing and allowing raw -Yvastewater to flow into the Trinity River are dire and this must be prevented. A confirming M&C will be circulated to ratify the above activities after the work has been performed.

The initial estimated overall amount of the emergency work was $1,510,000 and of that, the amount of reinforcing the sheet piling was $200,000. It has been determined that additional sheet piling and grading improvements are needed in order to secure an exposed river bank wall surface that could collapse on work crews during construction of the permanent repairs. It is anticipated that the additional work may cost up to $700,000.00. A change order will be processed to the existing contract with Circle C and actual costs will be reconciled at the end of the project.
