Contract C: HWY 20 Water Main Extension
DATE: June 29, 2017
INTRODUCTION
The purpose of this memorandum is to authorize award, pending approval by the
Department of Natural Resources State Revolving Fund (SRF) agency, of the Westside
Water System Improvements 2017: Contact C HWY 20 Water Main Extension. These
improvements include water main extension and connection to the Barrington Lakes water
system to the City of Dubuque water supply.
BACKGROUND
In December 2016, the City of Dubuque purchased the Vernon Water Tower, Vernon
water system and the Barrington Lakes water system from Central Iowa Water Association
(CIWA). The intent of the City's purchase was to assist these communities in becoming
compliant with Iowa Department of Natural Resources (IDNR) standards and provide the
necessary back-up water supply and fire suppression by connecting them directly to the
City's water supply.
The City is honoring the agreement with CIWA to meet the IDNR water permits for these
two systems in preparing plans to construct a water supply connection from the City of
Dubuque's water system to Vernon and Barrington Lakes. The IDNR water permit
required CIWA to provide a back-up or secondary water supply no later than December
31, 2016, however following the City's recent acquisition, the IDNR has granted a one
year time extension to provide the adequate back up. The IDNR requires the two water
systems be provided with a back- up or secondary water supply no later than December
31, 2017.
The intent of the City is to provide the primary water supply, by connecting to the existing
City of Dubuque water system which has multiple back-up sources, and abandon the
current primary water supply wells located in Vernon and Barrington Lakes.
For the City to meet the strict IDNR water operating permit connection completion date, it
was necessary for the City to seek financial and engineering assistance. The City turned
to the IDNR State Revolving Fund (Iowa SRF) program and hired IIW, P.C. consulting
engineers to prepare loan documents to secure funding for the project. On December 1,
2016, IIW, P.C. submitted the necessary preliminary engineering report, intended use
plan application, archeological and environmental assessment, and the self-assessment
Iowa Water System Viability documents to request the necessary funding. IIW, P.C. was
further retained to complete the final design plans, specification, and contract documents
for construction.
The project was sectioned into three distinct contracts, Contract A: Water Main Extension
from the English Mill Road pump station to North Cascade Road and Highway 20;
Contract B: English Mill Road pump station; and Contract C HWY 20 Water Main
Extension. Contracts A and B were competitively bid in April 2017, and successfully
awarded to Portzen Construction of Dubuque, Iowa, scheduled to start in June 2017 to
meet the December ls' deadline. Contract C was prepared for bidding and award.
DISCUSSION
IIW, P.C. working with City of Dubuque's water department staff have prepared
construction plans providing for the connection of the City's water supply to the
Barrington Lakes water system along Highway 20, known as Contract C. The project is
scheduled to be completed on or before December 1 , 2017.
Contract C includes the installation of a 12-inch water main from the end of an existing
water main located approximately 1,000 LF north of the North Cascade Road and Highway
20 intersection to the north to a connection with the existing water main at the cul-de-sac
of Forest Ridge Drive. The connection at Forest Ridge Drive will consist of construction of
a pressure control station. The project consists of approximately 3,700 LF of 12-inch PVC
water main. The project also includes various water main appurtenances including: fittings,
resilient seat gate valves, fire hydrants, mechanical and push-on joint restraints, etc.; as
well as erosion control including silt fence, topsoil removal and replacement, and seeding.
Traffic control is included in the project to maintain a safe work site for both the Contractor
and the public. This phase of the project will provide for a second connection or loop into
the Barrington Lakes area; the first connection will be made under Contract A.

The project was publicly advertised for bid on June 9, 2017. Sealed bids were received
and publicly read aloud at 10:OOam on June 28, 2017. In attendance were City of Dubuque
