RE: Westside Water System Improvements 2017
Contract A: English Mill & North Cascade Road Water Main Extension and
Contract B: English Mill Road Pump Station
(CIP 7402703)
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 Contracts A and B. Contract A, includes water main
extension and connection to the Vernon and Barrington Lakes Water Systems installed
along English Mill Road and North Cascade Road; and Contract B, includes installation of a
pumping station on English Mill Road at the intersection of Stone Valley Road.
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, 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
file:///T:\Engineering\WATER\BarringtonVernon\
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. They completed the design, prepared the bid documents for contracts A and
B, and assisted the City through the bid opening procedure. A detailed summary of the
work is as follows:
Contract A: English Mill Road & North Cascade Road Water Main Extension
The extent of the work consists of the construction of a 12-inch water main from near the
intersection of Stone Valley Drive and English Mill Road to the south to North Cascade
Road and along North Cascade Road to the west to near the intersection of Highway 20. A
water main extension into Barrington Lakes Subdivision at Barrington Drive along with a
pressure control station will be included in the project. The project consists of approximately
11,000 LF of 12-inch water main, including approximately 875 LF of 12-inch DIP and 10,125
LF of 12-inch PVC. Portions of the PVC water main will require directional drilling. The
project also includes various water main appurtenances including: fittings, resilient seat gate
valves, fire hydrants, mechanical and push-on joint restraints, etc. Rock is anticipated to be
encountered for the water main installation along portions of the proposed water main
alignment. Erosion control including silt fence, rolled erosion control product, topsoil and
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.
Contract B: English Mill Road Pumping Facility
The extent of the work involved in the City of Dubuque, Iowa Water System Improvements
2017 Contract B: English Mill Road Pumping Facility project consists of the construction of a
new pumping facility create a new pressure zone (Zone 7) in the City of Dubuque's
distribution system. The project consists of various components, the major items being: the
construction of a new 40'x50' block and brick building, with two 125 HP booster pumps, DIP
process piping, electrical, plumbing and mechanical components, standby power and site
work (including PCC parking and driveway, site grading, fencing, seeding and 12-inch DIP
water main installation including valves and fittings). Coordination with another project in the
same general area associated with the project will be required.
IIW, P.C. and the City are preparing a third and final contract as part of the water main
extension and connection to Barrington Lakes. The third contract, Contract C, includes a
final section of water main and pressure reducing stations to serve Barrington Lakes.
Contract C is scheduled for bid in May 2017.
DISCUSSION
Contracts A and B were publicly advertised on March 10, 2017, and a public hearing was
held on March 20, 2017. Bids were received and publicly read aloud at the City of
Dubuque's City Hall at 2:OOp.m. on April 6, 2017. IIW, P.C. was also in attendance and
