This Mayor and Council Communication is to authorize the preparation of plans and specifications for the Lake Arlington Lift Station Upstream and Downstream Parallel Relief Sanitary Sewer Gravity Mains Project located in the Carver Heights East Neighborhood. Portions of the existing wastewater collection system serving the Village Creek Wastewater basin are at capacity, with some areas experiencing wet weather overflows. Increased conveyance capacity is necessary to handle projected growth within the Village Creek Wastewater Basin which also includes the wholesale customer cities of Burleson and Crowley. In addition, it is anticipated that proposed development to the west of Crowley will lift wastewater into the Village Creek Basin starting in 2019. There are currently four projects (including M-257, Part 2) in various stages of design and construction to increase capacity in the upper reaches of the Village Creek Wastewater Collection System. The Fort Worth Wastewater Master Plan recommends the installation of a lift station and force main (No. 13) within the lower reaches of the Village Creek Basin. The proposed lift station, with an ultimate capacity of 80 MGD, will be placed upstream of Lake Arlington and the force main (42-inch diameter, 37,000 linear feet approximate) will extend from the lift station, around Lake Arlington and discharge into the existing Village Creek collection system north of Lake Arlington near the intersection of Lancaster Avenue (U.S. 180). The proposed scope of services for the upstream and downstream parallel relief sanitary sewer gravity mains include design for a 5,000 foot, 78-inch sanitary sewer main from an upstream connection point on M-257, Part 2 to a junction box at the proposed lift station; design for a 3,000 foot, 60-inch sanitary sewer main from the downstream connection point of the force main to the existing 60-inch sanitary sewer main located near the intersection of Cook's Lane and Lancaster Avenue; geotechnical investigation; environmental permitting; easement preparation; subsurface utility engineering; coordination with various agencies and assistance during construction. James DeOtte Engineering Inc., proposes to provide all the necessary design services for the upstream and downstream parallel relief sanitary sewer gravity mains for a fee of $469,270.00. Staff considers the proposed fee to be fair and reasonable for the scope of services proposed.
In addition to the contract amount, $1,105,000.00 is required for project management, utility coordination and real property acquisition.
Engineering for the Lake Arlington Lift Station Upstream and Downstream Parallel Relief Sanitary Sewer Gravity Mains project is one component of the overall project that includes project management, real property/easement acquisition, utility coordination, material testing, inspection, construction and contingencies. The overall project budget is $9,000,000.00. Design is expected to start in April 2018 and be completed by July 2019. Construction is anticipated to commence in November 2019 and be completed by March 2021. This project is part of the Water Department's Sanitary Sewer Overflow Initiative Program.
This project is anticipated to be included in a future revenue bond issue for the Water and Sewer Fund. Available cash within the Water and Sewer portfolio and the City's portfolio along with the appropriation authority authorized under the Callable Commercial Paper Program (CP) will be used to provide interim financing for this project until debt is issued. To the extent resources other than the Water and Sewer portfolio are used to provide interim financing, the Water and Sewer Fund will be charged interest that is equivalent to the overall rate of return being earned by the City portfolio (currently approximately one-percent annually). Should the City's portfolio not support the liquidity needed to provide an interim short-term financing source, another funding source will be required, which could mean issuance of securities under the CP Program or earlier issuance of Water and Sewer revenue bonds than is currently planned. Once debt associated with this project is sold, bond proceeds will be used to reimburse the Water and Sewer portfolio and the City's portfolio in accordance with the attached Reimbursement Resolution.
The City Council adopted the Water Department's Fiscal Year 2018-2022 Five Year Capital Improvement Plan on December 12, 2017, Mayor and Council Communication (M&C G-19187). This City Council adopted plan includes this specific project, with funding identified through the CP program to be reimbursed with future revenue bonds. In accordance with the provisions of the Financial Management Policy Statement, Staff anticipates presenting revenue-supported debt issuances to the City Council for consideration within the next three years. This debt must be issued within approximately three years to provide reimbursement for these expenses. If that does not occur, the costs will no longer be reimbursable by issuing tax-exempt debt and the funding source will have to be made whole through budgetary methods. Adoption of this resolution does not obligate the City to sell bonds, but preserves the ability to reimburse the City from tax-exempt bond proceeds.
This project will have no impact on the Water Department's operating budget.
M/WBE OFFICE – James DeOtte Engineering Inc., is in compliance with City's BDE Ordinance by committing to 12 percent SBE participation. The City's SBE goal on this project is five percent.
The project is located in COUNCIL DISTRICT 5.
