INTRODUCTION
The purpose of this memo is to seek authorization to award the contract for the Phase 1
17th Street Storm Sewer Improvements Project.
BACKGROUND
In January 2016, the State was awarded $95.7 million in HUD National Disaster
Resiliency Competition grant funds. Per the award, the City of Dubuque is to receive
$23.1 million for storm water infrastructure improvements associated with the Bee
Branch Watershed Flood Mitigation Project. The infrastructure improvements are as
follows:
1. Bee Branch Railroad Culvert Infrastructure Improvements involving the
installation of culverts from the Lower Bee Branch Creek, through Canadian
Pacific Railway property, to the Upper Bee Branch north of Garfield Avenue;
2. 22nd Street/Kaufmann Ave Storm Sewer Improvements involving the installation
of a large diameter storm sewer from 22nd & Elm up Kaufmann Avenue to the
Kaufmann & Kane intersection. The work includes inlets and local sewer
connections to the storm sewer and the complete reconstruction of the street and
other underground utilities along the street right-of-way corridor.
3. 17th Street/W. Locust Street Storm Sewer Improvements involving the installation
of a 96-inch diameter pipe from the Lower Bee Branch Creek through the
Canadian Pacific Railway tracks to 17th Street then to the west along 17th Street
and finally west along W. Locust Street towards Angella St. The work includes
inlets and local sewer connections to the storm sewer and the complete
reconstruction of the street and other underground utilities along the street right-
of-way corridor.
In October of 2016, the City Council passed Resolution 362-16 authorizing the
execution of the funding contract with the Iowa Economic Development Authority (IEDA)
for the City's receipt of$23,309,600.00 in Community Development Block Grant
Program Disaster Recovery - National Disaster Resiliency funds for the Bee Branch
Watershed Flood Mitigation Project.
The 17th Street Storm Sewer Improvements Project is Phase 12 of the Bee Branch
Watershed Flood Mitigation Project. The project involves the replacement of the existing
storm sewer with a large diameter storm sewer and additional storm drains (intakes)
from the Lower Bee Branch Creek along 17th Street to W. Locust Street. Improvements
will continue up W. Locust Street as far as the funding will allow. This work will require
the relocation and reconstruction of existing underground utilities to provide the
necessary space for the larger storm sewer. It will also require the complete removal
and subsequent reconstruction of the street.
The improvements will be constructed in multiple phases. Phase I involves the
construction of improvements on 17th Street through the Elm Street intersection. See
attached Exhibit A. Phase I improvements consist of the construction of 215 feet of 12-
foot by 7-foot box storm sewer along 17th Street through the Elm Street intersection.
Additional work includes high capacity storm sewer intakes and 175 feet of smaller
diameter storm sewers ranging from 15-inch to 30-inch. The work also includes the
relocation of 85 feet of 20-inch water main in the Elm Street intersection, and other
utilities within the street ROW. Finally, the work includes the reconstruction of the paved
surface of Elm Street and E. 17th Street.
On July 17, 2017, the City Council held a public hearing on the proposed plans,
specifications, form of contract and estimated cost for the Phase 117th Street Storm
Sewer Improvements Project. The City Council subsequently adopted Resolution 264-
17 approving the plans, specifications, form of contract and estimated cost for
Phase 117th Street Storm Sewer Improvements Project, in the estimated amount
$1,677,530.00.

Improvements Project. Portzen Construction, Inc. of Dubuque, Iowa submitted the low
