SUBJECT: Central Avenue Corridor Streetscape Master Plan Work Session
DATE: December 12, 2022
INTRODUCTION
This memorandum presents information regarding a work session presentation from
consultant RDG Planning & Design on the Central Avenue Corridor Streetscape Master
Plan developed with community input and direction from technical and steering
committees. This project will help to implement a High Priority of the City Council's
2022-2024 Policy Agenda -- Central Avenue Revitalization Plan: Adoption, Direction,
and City Actions. The Council presentation and the draft Master Plan are enclosed.
This work session provides information for newer City Council members and serves as
a refresher of the details for those who received this information at May 2019, February
2020, and December 2021 work sessions.
BACKGROUND
In 2016, the City of Dubuque asked Iowa State University Extension and Outreach
Community and Economic Development for assistance in assessing opportunities for
economic redevelopment and improvement in the quality of life for residents along the
Central Avenue Corridor, which abuts Dubuque's historic and diverse Washington
Neighborhood, a focus of redevelopment since 2005.
This corridor connects Dubuque's central downtown and Historic Millwork District to the
city's North End. It features a wide variety of historic buildings offering commercial and
retail opportunities on the ground floor and residential spaces on upper floors. The goal
of this initiative is the economic revitalization of the Central Avenue Corridor through
community engagement, educational outreach, and community -informed storefront and
streetscape design. Central Avenue Corridor stakeholders include business owners,
employees, patrons, residents, landlords, social service agencies, community leaders,
the City of Dubuque, and partner agencies.
In May 2018, the Economic Development Department released a Request for Proposals
for a consultant to develop a Central Avenue Corridor Streetscape Master Plan for the
area between 11th and 22nd Streets.
In July 2018, a Master Plan consultant contract was signed with RDG Planning &
Design (with WHKS Engineers sub consulting to provide information on the feasibility of
two-way traffic along the corridor). RDG has worked with a variety of stakeholders, as
more fully described in the draft Central Avenue Corridor Streetscape Master Plan.
The Steering Committee membership was as follows:
• Jill Connors, Planning Services Department
• Jon Dienst, Engineering Department
• Wally Wernimont, Planning Services Department
• Gina Bell, Sustainable Community Coordinator
• Jason Neises, Community Foundation of Greater Dubuque
• Marie Ware, Leisure Services Department
• Paul Davis, Public Works Department
• Dave Lyons, Greater Dubuque Development
Project Objectives
The creation of the Central Avenue Corridor Streetscape Master Plan between 11th and
22nd Streets in the Washington Neighborhood is being directed by the Economic
Development Department in partnership with other organizations working in the corridor,
with assistance from the Planning Services Department. Once the consultant was
selected, we engaged representatives from key City departments, key community
partners, and Central Avenue Corridor stakeholders. Project objectives include:
1. Address the Corridor's current state of aesthetics as well as provide guidelines
for future improvements, and redevelopment of public infrastructure elements
within the Corridor.
2. Provide design guidelines for linking complimentary uses, preserving the history
and identity of the neighborhood, and improving walkability as well as
recommending options for streetscape furnishings and landscaping.
3. Address conditions and opportunities for the Corridor's future transition from its
recent status as a one-way State highway to a pedestrian -friendly two-way city
street such as traffic calming and Complete Street strategies.
2
4. Outline simple, cost-effective strategies that can be reasonably achieved in a
short period of time as well as more complex, long-term strategies that will
require greater coordination and expense.
DISCUSSION
The following will be considered as the Plan moves from adoption to implementation.
Guidelines for Future Improvements
During public engagement, stakeholders indicated that childcare, restaurants, lighting,
and small business were at the top of the list of their desired additions to the Corridor.
This provides excellent direction for moving forward.
Design Guidelines
The plan recommends preserving the Corridor's architecture; the addition of more
landscaping, trees, and plantings; a focus on economic development while preventing
gentrification; addressing perceived or real safety issues; and integrating art into all the
design elements and improvements. These will all be considered when implementing
the plan.
Traffic Patterns
A planning -level capacity analysis has been undertaken by WHKS to analyze the
feasibility of converting Central Avenue to two-way traffic. It should be noted that a
complete traffic study will be needed to determine the full impact and modifications
needed to convert the Central Avenue Corridor to two-way traffic, if such a
determination is made. This is not a forgone conclusion.
In support of the City Council's having identified the revitalization of the Central Avenue
Corridor as a High Priority, and as part of the FY2020 5-year recommended budget, the
City Council had approved $240,000 over three years for implementation of the Central
Avenue Corridor Streetscape Master Plan. The approved FY2023 5-year CIP budget
request included $150,000 in FY2023 and $25,000 in FY2024 for implementation of
some of the beautification recommendations.
Also included in the Engineering Department's FY2023 5- year CIP budget is $400,000
for the design of streetscape/traffic improvements and $265,000 for a 2-Way
Conversion Study for Central Avenue and White Street. This includes funding for a
complete traffic study that will evaluate signalized intersections in the Corridor; identify
improvements or modifications to support traffic demands; and to consider transit
needs, bike and pedestrian needs, and sustainability.
3
During the work session presentation, City staff along with staff from RDG and the
Greater Dubuque Development Corporation will describe steps to date, details of the
plan as informed by additional public input sessions and solicit input from City Council.
Short-term and Long-term Strategies
These will be identified as City staff work with stakeholders and partners to develop
specific implementation.
RECOMMENDATION/ ACTION STEP
We recommend the City Council review and comment on the presentation and the draft
Master Plan, and then provide direction for City staff to move forward with submittal of a
final version of the Central Avenue Corridor Streetscape Master Plan for adoption at a
subsequent meeting.

03 1 Engagement Themes
•••
(n Embrace the Washington Neighborhood
QJ This sentiment came up often during conversations. Most of the committee members believe that the citizens and businesses currently residing in the
neighborhood are the target audience for the projects proposed improvements. Getting their feedback early and often will be key as the project moves
Eforward. When speaking to "where the project could go wrong,"several members identified gentrification of the neighborhood as a concern.
The streets should be complete! Pedestrians are number one.
When speaking to the objectives for the master plan, most of the respondents agreed that pedestrian -friendly streets and safety area primary project
element. Respondents also spoke to creating streets that welcomed bus, bike and car traffic in a safe and friendly manner.
The street should be designed for two-way traffic.
When discussing vehicular circulation and the streer' future traffic patterns, the committeeconfirmed that the City anticipates transitioning from one-way
to two-way traffic after the completion of the SouthwestArterial project. The design team was advised that the street will be overlaid with asphalt in 2019 os
part of the transition ofjunsdiction from the Iowa DOT to the City of Dubuque.
Tt1 Integrate arts and culture, create a sense of place.
Manyindividuals spoke about creating a streetscope that is equitable and inclusive. The improvements planned should embrace the multiple cultures,
families and individuals who live, work and play within the corridor and adjacent neighborhoods. When discussing the physical extent of the project
respondents confirmed that the corridor will be its awn district unique to the Washington Neighborhood.
E
W
2019
The Corridor's architecture is unmatched.
Historically speaking the CentrafAvenue Corridor is rich. Several properties are listed on the national register. The plan must be sensitive to this and embrace
the past.
Create a "greener" experience.
5evemi of the committee members spoke to the limited amount ofgreen / open space within the corridor. Respondents identified several areas where
landscaping, trees and plantings could be integrated.
Maintenance matters.
The design should take into consideration opportunities to reduce long-term maintenance. The design team was encouraged to work with the multiple city
departments (leisure services, public works, etc.) who will regularly have to maintain the corridor.
rM
Economic vitality.
This phrase was shared several times when the committee was asked to define what theproject's impact should be. Members were careful to state that
development should not gentrify the neighborhood, but rather support their needs.
Safety Y is key.
The committee spoke to this in multiple ways. There is a perception in the community that this area is unsafe, yet those people who live here do not believe It
Wto be a problem. The plan must considerprovisions for improving the safety —perceived and real.

Multiple implementation measures are
currently underway within the corridor. They
are as follows:
•The City of Dubuque has obligated
capital improvement dollars toward the
implementation of a green alley between the
1800 and 1700 black, near the Curve.
•Upon adoption of this master plan, the City
will be able to apply capital improvement
dollars towards updating the site furnishings,
landscaping and other amenities.
-Adoption of the master plan will allow the
City to begin allocating monies towards
a 2024 CIP request that will help with the
plaza and other portions of the streetscape
concept.

Section 1: Introduction
I. Introduction
Within the city of Dubuque there are many
sites full of character and potential, and the
Central Avenue Corridor is a prime example.
Currently, this road is a southbound, one-
way thoroughfare. Once the arterial is
reconstructed, Central Avenue will be an
enormous opportunity for community
revitalization. Particularly in the heart of
Dubuque, Central Avenue has historically
been the"main street"for the Washington
Neighborhood, and so it became desirable to
envision a new street which better serves its
neighborhood.
The Washington Neighborhood
One of Dubuque's oldest districts, the
Washington Neighborhood is filled with
historic buildings. Among its first inhabitants
were Irish and German immigrants,
employed in the nearby industrial districts.
To this day, the neighborhood maintains its
connection to the industrial relics. Recent
efforts by the city have been driven towards
revitalizing the Washington Neighborhood,
including a neighborhood master plan.
Central Avenue
The segment of Central Avenue addressed
by this plan runs between 11th and 22nd
Street. Prior to 1921, Central Avenue was
two separate streets, Couler Avenue to the
north of 18th and Clay to the south. The
introduction of a state highway gave them
reason to converge, and shifted the corridor's
focus from pedestrians to vehicles. With the
removal of Highway 52 designation, there
is an opportunity to rediscover pedestrian -
friendly streets, architectural gems, and to
restore economic vitality.
Streetscape Master Plan
The Central Avenue Corridor from 11 th
Street to 22nd Street in the Washington
Neighborhood connects Dubuque's central
downtown and Historic Millwork District to
the city's North End. It features a wide variety
of historic buildings offering commercial and
retail opportunities on the ground floor and
residential spaces on upper floors.
The purpose of the Central Avenue Corridor
Streetscape Master Plan is to engage
stakeholders in the process to prepare for
and guide this renaissance. Project objectives
include:
•Be highly illustrative with conceptual
renderings of streetscape improvements.
•Provide guidelines for the Corridor's future
pedestrian -friendly city street.
•Provide design guidelines for linking
complimentary uses, preserving the history
and identity of the neighborhood, and
improving walkability.
•Recommend streetscape furnishings such
as pedestrian scale lighting, way -finding
systems, greenspace creation, and public art.
•Promote creative, innovative, and
sustainable opportunities to beautify and
bring a cohesive sense of identity and place
to the corridor.
•Recommend landscaping such as street
trees, decorative planters, planting beds.
•Outline simple, cost-effective strategies
that can reasonably be achieved in a short
period of time as well as more complex,
long term strategies that will require greater
coordination and expense.

Section 2: Public Input
II. Public Input
From the outset, this plan sought to
consider the perspectives of locals from
the Washington Neighborhood and Central
Avenue Corridor. The values of people who
use the area regularly should be instrumental
in guiding design decisions. With this in
mind, various activities were planned to
engage with the public, and encourage them
to contribute their personal feedback.
Initial Engagement
In preparation for The Central Event and
Workshop, the need for public input was
advertised, and a first effort at collecting
feedback was initiated. Meetings were
held with groups, such as the Fountain of
Youth, to gain specific perspective feedback,
and members of the steering committee
canvased the Washington Neighborhood.
A -frames were placed around the
community with prompts to encourage the
public to think about future developments.
"Tweet Boxes" attached to the frames gave
people the opportunity to write down their
suggestions and submit them for review.
In general, a tremendous effort was made
to advertise the public input sessions with
banners, a press release, a front page article
in the daily herald, and more.
The Central Event
On the evening of Tuesday, September 1 1th,
the section of 18th Street between Central
Avenue and White Street was closed. Local
food vendors and musicians set up in the
street and informational signage, feedback
boards, and furnishing demonstrations
were displayed. The event was heavily
advertised and well attended by workers
and residents of the neighborhood. Over the
course of the evening, hundreds of people
expressed their opinions, brainstormed new
opportunities, and had fun. Feedback was
collected through various activities including
the tweet boxes, surveys, visual prompts,
interactive maps, and conversation.
Workshop and Drop -in Hours
The rest of the week was committed to
interpreting the feedback, meeting with
key stakeholders, and developing a draft
vision for the Central Avenue Corridor.
Organized within this workshop were more
drop -in hours to meet with the design team
privately. This opportunity gave a voice to
those who were less comfortable expressing
themselves publicly.

The Spring Fling on Central
After a number of months spent interpreting
community input and developing the plan
for Central Avenue, the project team put
together another public input session. On
April 2, 2019, the public was invited to the
Spring Fling on Central. Similar efforts were
made to advertise the event, and community
members came back to offer their feedback
on the proposed master plan exhibit. Food
was again provided to participants, and the
result was a friendly environment promoting
discussion about Central Avenue's future. The
event made front page news and generated
many helpful responses.
Specifically, participants were asked to
review an exhibit of the master plan and
fill out a survey. While everybody shared
excitement for the proposed improvements,
certain elements were prioritized over
others. The survey results provided almost
unanimous approval for the plan, and a more
thorough understanding of the community's
priorities.

The Business Roundtable
Discussion
As a part of The Spring Fling on Central, local
business owners who would be affected by
the corridor's development were notified
and encouraged to attend the business
roundtable discussion. The purpose of this
gathering was to present the Central Avenue
Corridor Master Plan, receive feedback, and
address the concerns of local businesses
Discussion points included:
•Two-way traffic conversion: Participants
expressed interest in understanding
the timeline for the one way to two way
conversion. Attendees were informed
that the City of Dubuque is planning to
complete an in-depth transportation study
to determine if one-way or two-way traffic
patterns are best for the City. This project
is anticipated to include additional public
input opportunities, careful review of ingress
and egress from existing properties and an
assessment of traffic signals.
•Parking: attendees expressed concern over
the removal of on street parking.
•Semi -truck traffic and business deliveries:
attendees noted that several business will
continue to rely on truck traffic for deliveries.
The group discussed including provisions
within the preliminary and final design to
accommodate deliveries.
•Project costs: participants asked about the
funding for the project. As of this writing, the
total projects costs have not been finalized.
The City will seek outside funding through
grants to help pay for the project.

Central Avenue Corridor
2022 Public Input Summary
During the spring of 2022, multiple design
input meetings were held with the property
owner's in the immediate vicinity of the area
known as"The Curve"which is the lateral
shift in Central Avenue at 18th Street. The
following themes are direct quotes from the
stakeholders, which effectively reinforced the
feedback received in 2019.
"I'd like to not see so many vacant buildings"
"We need to add more parking"
"Keep it flexible"
"green it up....sidewalks - proper lighting... like Grandview -
nice lighting... benches... plantings....narrow the street"
"Make it accessible, ADA compliance - accessibility is a big
thing for us"
"I'm concerned about what happens during construction -
I've spent a lot of money and would like to be here long term"
"New street lights - sidewalks, cleaning it up - some more of a
flexible area vs a stage"
"The plaza you had love it - hope that's still in the cards. ADA
access into the buildings - I would like to avoid ramps - I like
the original plan"

Section 3: Strategic Direction
III. Strategic Direction
The result of the public engagement,
committee meetings, and other learning
opportunities was a set of guiding principles
for the development of the project area. The
following themes represent the community's
desires and City's objectives in no particular
order.
Embrace the Washington
Neighborhood
Committee members and the public agree
that the citizens and businesses currently
residing in the neighborhood are the
target audience for the project's proposed
improvements. When speaking to "where the
project could go wrong," several members
identified gentrification of the neighborhood
as a concern.
Design Streets for Both One -Way
and Two -Way Traffic
When discussing vehicular circulation and
the street's future traffic patterns, the City
anticipates exploring street alternatives after
completion of the Northwest Arterial project.
Pedestrians are Number One
When speaking to the objectives of the
master plan, most respondents agreed that
pedestrian -friendly streets and safety are a
primary project element. Respondents also
spoke to creating streets that welcomed
bus, bike, and car traffic in a safe and friendly
manner.
Integrate Arts and Culture
The planned improvements should embrace
multiple cultures, families, and individuals
who live, work, and play within the corridor
and adjacent neighborhoods. When
discussing the physical extent of the project,
respondents confirmed that the corridor
should be its own district. The benches, trash
cans, signs, landscaping, artwork, and other
enhancements will be specific to this area
(exclusive of typical street lights, drinking
fountains, etc. that are "City standards").
Reduce Maintenance
The design should take into consideration
opportunities to reduce long-term
maintenance. The design team worked with
multiple City departments (leisure services,
public works, etc.) that will regularly have to
maintain the corridor.
WE
Central Avenue Corridor
Preserve the Corridor's
Architecture
Historically speaking, the Central Avenue
Corridor is rich. Several properties are listed
on the National Register. The plan must be
sensitive to this and embrace the past.
Create a "Greener" Experience
Currently, there is a limited amount of green /
open space within the corridor. Respondents
identified several areas where landscaping,
trees, and plantings could be integrated.
Encourage Economic Vitality
The development along the corridor
should invite economic opportunity to the
neighborhood. Committee members were
careful to state that development should
not gentrify the neighborhood, but rather
support their needs.
Prioritize Safety
There is a perception in the community that
this area is unsafe, yet those people who live
here do not believe it to be a problem. The
plan must consider provisions for improving
general safety, whether perceived or real.
These themes helped to organize
community values and gave us a framework
for the coming designs.

Section 4: Neighborhood Fabric
IV. Neighborhood
Fabric
The stretch of Central Avenue adjacent
to the Washington Neighborhood has a
unique character. As part of the inventory
process, the design team was led on an
architectural tour of the Central Avenue
Corridor by local expert Jason Neises. An
abundance of detail was discovered beneath
the face of the street. These details are easy
to miss if you aren't paying attention, and
are often overlooked by the vehicles which
currently dominate the street. A transition
to a pedestrian -friendly environment will
encourage people to slow down and pay
more attention to the collection of cultural
relics, thus making the character of the
corridor more obvious.
Additionally, the architectural character
of the area can be expressed through
design. Infrastructure introduced in future
developments should contain the same
elements, or abstractions of them, in a way
that calls attention to the history of the
Central Avenue Corridor. These details will
blend together with modern elements to
tell the site's story and increase the cultural
capital of the neighborhood.
With these concepts in mind, a library of
details, textures, and architectural elements
was assembled to inform design decisions
throughout the workshop.

I nteg rated Art
After a cache of architectural and historical
knowledge had been accumulated, the
design team's understanding of the corridor
could be integrated within the physical
details of the vision. Several concepts were
developed through this method.
The letter"C" made itself apparent through
alliteration (Central Avenue Corridor,
Couler, Clay), and was used as a branding
symbol across concepts. The redundancy of
significant architectural features was another
element to include within the corridor's
details. Arches, steel girders, and prism glass
tiles were a few of these elements. Small
organic decorations are found all over local
buildings, and so nature -inspired detailing
became a theme as well.
Interlocking "Cs" inspire a railing pattern and a unique paver.

Section 5: Opportunities
V.Opportunities
In applying key values and themes to the
design strategy, a series of opportunities was
revealed. The regional context of adjacent
corridors was observed to determine each
street's role in pedestrian and vehicular
transportation. Corridors and crossroads
could then be optimized for their respective
audiences.
For example, 15th Street was admired for
its connection to several community parks,
stretching from Grant Park down to the
Bee Branch Creek Greenway. Being a less
desirable path for cars as well, 15th street
proved to be an ideal pedestrian corridor.
Likewise, 18th Street proved to be important
as a pedestrian route, and showed potential
for the introduction of a common space at its
Central Avenue terminus.
Beyond its regional context, the Central
Avenue Corridor was carefully considered to
reveal distinct zones around which designs
could be determined.

The Corridor
Shown below is the overall, proposed
framework diagram for the Central Avenue
Corridor between 11th and 22nd Streets.
Key to this diagram is prioritizing the
intensity of improvements between 14th and
19th Streets, identified as the "Corridor Core."
Transitional areas north and south of this
core continue strategic improvements with
slightly less quantity and intensity.
Pedestrian -focused areas, on -street parking,
bus stops, and signalized intersections are
also conceptually shown and will guide
future efforts to advance more detailed
roadway geometrics and streetscape design.

intersections with Central Avenue critical
moments along the corridor.
This area also features the largest

Section 6: Transportation
VI. Transportation
Within the district, Central Avenue is the
road with the most traffic. With this in mind,
it was necessary to envision the future of
motorized and non -motorized transportation
throughout the corridor.
The Washington Neighborhood has the
highest rate of bus ridership and the highest
number of car -free households within the
City of Dubuque. Public transportation
and alternative modes of movement are
currently a key part of this district and must
be carefully considered within proposed
improvements for the Central Avenue
Corridor.
Two-way Traffic Analysis
A planning -level "capacity analysis"was done
to analyze Central Avenue with two-way
traffic. Additional traffic study will be needed
for the full corridor. The purpose of this study
was to determine if two way traffic would be
feasible, should the City decide to study this
in detail at a future time.
The intersections analyzed were the Central
Avenue intersections with 1 1th Street,
14th Street and 20th Street. The capacity
of the intersections was analyzed using the
procedures outlined in the Highway Capacity
Manual 2010 (HCM).The intersections
were modeled using Synchro Studio 9 with
SimTraffic 9.
The analysis was done using directional
intersection traffic counts provided by
Dubuque Metropolitan Area Transportation
Study (DMATS). DMATS provided traffic
counts for the years 2020, 2025, 2030, 2035,
2040 and 2045.The 2045 volumes were
modeled using Synchro and the capacity at
the three intersections provided acceptable
levels of service operating with two-way
traffic. A southbound left turn lane was
needed at the intersection of Central Ave /
20th Street.
It should be noted that a complete traffic
study will be needed to determine the full
impact and modifications needed to convert
Central Avenue to two-way traffic from 4th
Street to 22nd Street"
43
Central Avenue Corridor
The Importance of Public
Transportation
The following maps depict the importance
of reliable public transit systems along
Central Avenue. As is shown, the highest
concentrations of car -free households falls
along the Central Avenue Corridor and
within the Washington Neighborhood.
Similarly, populations of seniors, youth, and
disable people who cannot drive or have
trouble driving are highest in this area as
well. The people who will depend on this
corridor's development the most need access
to public transportation that is safe, covered,
reliable, and prioritized along Central
Avenue.

Section 7: Streetscape
VII. The Streetscape
The overall master plan vision for the Central
Avenue Corridor Streetscape embraces the
following critical directions, as defined by
the public input received during the public
engagement period.
Design the Street for Flexible
Traffic Patterns
To accommodate both one-way and two-
way traffic, the design respects the traffic
analysis done by WHKS. Designated turning
lanes were added at key intersections and
oversized vehicles were given extra room to
turn in tight areas.
Embrace the Washington
Neighborhood
While evaluating the regional context, the
intersections at 15th and 18th Streets were
selected as optimal pedestrian nodes, as
they provide a connection to several key
locations within and beyond the Washington
Neighborhood. This physical connection
should be developed with similar content to
Central Avenue to establish the corridor as an
extension of the neighborhood. Furnishings
and the material palette are also defined by
the visual preferences of the community, as
collected in the community input sessions.
Pedestrians are Number One
To meet this objective, the vision needed to
consider the interactions between vehicular
and pedestrian traffic. Streetside bollards,
crosswalk bumpouts, and a raised crosswalk
at 18th Street address this need. The "Central
Commons" is designed as a pedestrian
hub, to be used as a park, event space, and
general core of the corridor.
Integrate Arts and Culture
The existing character of the corridor is
blended into new streetscape features to
develop a stronger sense of place. Bus stops,
bollards, and other place -making elements
exhibit this strategy.
Reduce Maintenance
Streetscape features maintain a defined
setback from the curb, and atypical curbs
(bumpouts) will be mountable for ease of
maintenance. Additionally, the use of custom
streetscape features should be limited, as
standard models are easier to replace.
Preserve the Corridor's
Architecture
The vision shows concern for Central
Avenue's architectural character. Key
buildings are highlighted and details are
captured in integrated art.
Create a "Greener" Experience
The corridor is vegetated with street trees,
planters, and planted buffers on streetscape
edges.
Encourage Economic Vitality
The nature of the project will encourage
pedestrian activity along Central Avenue
storefronts. Both northbound and
southbound bus traffic has been located
so that economic undertakings can be
concentrated along the corridor.
Prioritize Safety
Various types of lighting and cameras will
ease safety concerns. Trees throughout the
corridor will be pruned high enough to
maintain visibility.

Central Avenue Corridor
Streetscape Vision
The vision resulting from the public
engagement reflects community values. The
image below is a typical cross-section for the
corridor. Where there are no dedicated turn
lanes, there will be room for two-way traffic
and parallel parking on both sides of the
road. Ample room will be left for pedestrians
and a paver boulevard to separate sidewalks
from the road.
The cross-section varies throughout the
corridor when necessary, always considering
the values outlined in the strategic direction,
as well as the design elements derived
from them. The following pages depict the
proposed improvements along the Central
Avenue Corridor from 22nd Street to 11 th
Street.

Central Avenue Corridor
A Note About the Curve
During the Spring and Summer of 2022, the
City of Dubuque sought additional input on
the proposed plan for the gathering space
proposed on 18th street.
The City and RDG met with the majority of
property and business owners between 1700
and 1900 blocks to gain their feedback on
the proposed changes.
Two options were discussed and presented.
Both options do not decrease parking within
and around 18th street.
Option A does not contain a direct connection
to Central Avenue and provides the following
Pros & Cons:
PROS:
One large plaza
Max of outdoor seating
Less alley traffic
Protected drop-off
Option B contains a one-way in, allowing
drivers to exit Central Avenue into the alleyway
or head eastbound toward White Street.
PROS:
Vehicle connection to Central
Some outdoor seating
Wider walks along 18th
CONS
CONS: Increased pedestrian -vehicle conflicts
Dead-end feel Smaller plaza
Narrower walks along 18th More alley traffic
Loss of vehicle connection to Central One-way traffic from Central
Option A
Option B
64
Section 1: Introduction
During the design workshop in June of 2022,
there were advocates for both options, with
both advocate groups acknowledging that
either option was an improvement over
earlier plans presented and shared in 2019.
After the workshop, the design team
requested a review by the City's Engineering
Department. The comments received are as
follows.
The City's engineering department prefers
Option A
This option protects pedestrians from
vehicles traveling off Central Avenue,
minimizes through traffic in the alley
(which also protects pedestrians in alley)
between Central & White, and traffic
calming measures for reduced speeds along
Central Ave.
Note that the alley is not designed for high-
speed or high -volume traffic. The closure
of this plaza to the alley is the safest to
minimize pedestrian and vehicle conflicts.

Section 7: Streetscape
Urban Edge Treatment
Description:
Methods for the separation of the Central
Avenue Streetscape and adjacent land,
particularly at parking lots. Various methods
should use screen walls and planting
material to create clear distinctions between
the streetscape and adjacent land. The
urban edge at City Hall should be used as
precedent.

Section 8: Implementation
VIII. Next Steps
Multiple implementation measures are
currently underway within the corridor. They
are as follows:
-The City of Dubuque has obligated
capital improvement dollars toward the
implementation of a green alley between the
1800 and 1700 block, near the Curve.
-Upon adoption of this master plan, the City
will be able to apply capital improvement
dollars towards updating the site furnishings,
landscaping and other amenities.
-Adoption of the master plan will allow the
City to begin allocating monies towards
a 2024 CIP request that will help with the
plaza and other portions of the streetscape
concept.

Council Approval is Critical
• Sends a needed positive message to local businesses and building owners
who are (or are considering) investing in the corridor.
• Unleashes funds for critical infrastructure improvements.
• Assures that the "holistic" plan built through community engagement
remains the polestar for future development (versus continuing disjointed
or conflicting efforts)
• Allows staff to present Central Avenue projects to new federal funding
sources as "shovel ready".
