RE: 17t" Street Storm Sewer Improvements Project - Elm to Heeb
CIP# 2642769, PROJECT# 1X0005
INTRODUCTION
The attached resolution authorizes the award of the construction contract for the 17tn
Street Storm Sewer Improvements Project - Elm to Heeb.
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. 17t" 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 17t', Street then to the west along 17t" 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 o� 2016, the City Council passed Resolution 362-16 authorizing tFi�
execution of the funding contract with the lowa 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.
DISCUSSION
The 17th Street Storm Sewer Improvements Project is one part of the multi-phase Bee
Branch Watershed Flood Mitigation Project. It involves the replacement of the existing
storm sewer with a large diameter storm sewer and additional storm drains (intakes)
from the Bee Branch Creek along 17t" Street through Elm Street to W. Locust Street
and then up W. Locust Street towards Rosedale Avenue as funding allows. 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 17t" Street Storm Sewer
Improvements Project will be constructed under multiple contracts. The first, completed
in the fall of 2017, involved the construction of improvements on 17t" Street from the RR
tracks through Elm Street.
The 17t" Street Storm Sewer Improvements Project - Elm to Heeb ("the Project") limits
will start from where the first contract left off just west of Elm Street. From there it will
extend to Heeb Street, just west of Central Avenue. See attached public outreach letter.
The Project involves the construction of approximately 1102 linear feet of 10-foot by 5-
foot concrete box culvert (either cast-in place or precast) with cast in place connections
on both the west and east ends of the project. The project also includes local storm
sewer and intakes, roadway reconstruction with HMA pavement, PCC driveway,
sidewalk, and curb ramp reconstruction, PCC wall, railing, and step construction, water
main replacement, sanitary sewer replacement, temporary storm water management,
dewatering, mobilization, electrical conduits, fiber vaults, traffic signal replacement,
miscellaneous restoration, erosion control, and traffic control.
The project will have internal traffic control stages to minimize the inconvenience to
citizens driving through the corridor. For example, if the 17t" street and Washington
Street intersection and the 17'" street and Jackson Street intersection are both closed,
the White Street and Elm Street will remain open to traffic across 17t" Street.
Subsequent contracts are under development that include improvements along 17t"
street from Heeb Street to W. Locust Street and along W. Locust Street from 17t" Street
towards Rosedale Avenue. These additional phases of construction will occur in 2019
and 2020.
PUBLIC ENGAGEMENT
The Engineering staff held a public information meeting for this project on October 24rn
2017 at the Multicultural Family Center. Several letters were sent to property owners
and residents in the affected properties on the project before the public meeting.
Engineering staff also held "office hours" so questions could be asked individually by
2
property owners if needed. A project website is located at:
h[tp:llwwGv.cityafduf�ur�u�.arc.�118�4�� 7th-St-W-Lo�ust-St-Pra�ect. This is on the Bee
Branch Flood Mitigation area of the City's website.
There will be a need to acquire temporary construction easements for some properties.
These easements will be acquired prior to construction. Property rights letters and
related temporary easement documentation have been mailed out to property owners.
The City will follow the procedures outlined with the lowa DOT in acquiring temporary
construction easements.
