Conduct a public hearing, deliberate and adopt a Resolution recommending that the
City Council adopt the Downtown Dublin Streetscape Plan and amend the City of Dublin
Streetscape Master Plan.
PROJECT DESCRIPTION:
Background
In 2005, the City adopted the City of Dublin Figure 1: Project Area
Streetscape Master Plan to guide the
continuation of good streetscape design
in the public right of way throughout the
City, including the Downtown. The
Streetscape Master Plan created a city-
wide inventory of existing streetscape
elements such as benches, trees, bus
shelters, trash receptacles and signage
and made recommendations on
features that should be continued,
added and phased out as development
occurs.
In 2011, the City adopted the Downtown

Packet Pg. 32
Dublin Specific Plan to guide and encourage reinvestment in the Downtown and create
a vibrant and dynamic commercial and mixed -use center. The Downtown Dublin
Specific Plan area is located in the western area of Dublin and is 284 acres in size. It is
bisected by I-680 which creates the framework for the Plan's three districts: Retail
District, Transit -Oriented District and Village Parkway District as shown in Figure 1. The
Downtown Dublin Specific Plan provides development standards and design guidelines
for the development of private property. A recent amendment to the Downtown Dublin
Specific Plan incorporates the Downtown Dublin Preferred Vision (Preferred Vision) in
Chapter 4, including a new Town Square and future street grid, which are described in
more detail below. In addition, Chapter 5 establishes the circulation and infrastructure
improvements on both private and public property required to lead the way for private
development. The Downtown Dublin Specific Plan outlines the extension of Saint
Patrick Way, improvement of east -west pedestrian pathways on private property in the
Retail District, which should also connect to the Transit -Oriented District, and creation of
private outdoor spaces.
As part of the Downtown Dublin Specific Plan, a Community Benefit Program was
established to ensure that developers provide a benefit to Downtown in exchange for
receiving a higher density on their property. The Downtown Dublin Specific Plan
provides examples of appropriate community benefits that might be provided by
developer, which include infrastructure improvements such as enhanced landscaping,
pedestrian connections, parks, public plazas, gathering spaces, etc.
The proposed Downtown Dublin Streetscape Plan will guide future public and private
investment in a unified streetscape and a branding/identity program that strengthens the
identity of the Downtown. The improvements identified in the Downtown Dublin
Streetscape Plan would serve as a list of projects that could be used as part of the
Community Benefit Program as well as future City projects.
In July 2017, the City Council approved a consultant contract to hire landscape
architects, Royston Hanamoto Alley and Abey (RHAA) for preparation of the Downtown
Dublin Streetscape Plan. Staff has worked with RHAA to accomplish this and the
attached document is a result of this collaboration.
In November 2019, the City Council approved the Preferred Vision for a portion of the
Retail District bound by Regional Street, Amador Valley Boulevard, Amador Plaza Road
and Dublin Boulevard, which includes three primary components: 1) siting of a Town
Square; 2) establishing a new street grid network; and 3) creating a Downtown
character. The proposed Downtown Dublin Streetscape Plan supports implementation
of the Preferred Vision through inclusion of the Town Square and new street grid
network.
ANALYSIS:
The Downtown Dublin Streetscape Plan is a planning tool that will ensure a consistent
look and feel for Downtown by creating a framework for future streetscape
improvements. The intent of the Downtown Dublin Streetscape Plan is to:
Page 2of9
Packet Pg. 33
Assist in the implementation of existing Downtown Dublin Specific Plan.
The Downtown Dublin Specific Plan created the framework for private
development in the Downtown and encouraged mixed -use development that is
friendly for all modes of transportation with a focus on the pedestrian. The
streetscape is an important piece to successful implementation of the Downtown
Dublin Specific Plan's vision.
Downtown Dublin Specific Plan Vision: Downtown Dublin will
be a vibrant and dynamic commercial and mixed -use center
that provides a wide array of opportunities for shopping,
services, dining, working, living and entertainment in a
pedestrian -friendly and aesthetically pleasing setting that
attracts both local and regional residents.
Strengthen the identity of the Downtown through a unified streetscape and
identity program. Currently, streetscape improvements are guided by the
Streetscape Master Plan which is a city-wide document encouraging uniformity
throughout the City. The Downtown Dublin Streetscape Plan will focus on the
Downtown to address the community's specific goals to strengthen the identity of
Downtown in an effort to make it a social center of the City.
' Provide a mechanism for promoting Capital Improvement Projects with
streetscape improvements built in. The Downtown Dublin Streetscape Plan
will outline streetscape improvements that can be incorporated over time. If the
City has a document that clearly identifies preferred landscape and hardscape
features, those features can be incorporated into the design of future Capital
Improvement Projects.
Community Outreach
City Staff and RHAA have worked with input from the community to create a
streetscape plan that implements the vision as set forth in the Downtown Dublin Specific
Plan and, more recently, the Preferred Vision. The process involved evaluation of
Downtown as it is exists today, identifying opportunities and obtaining input from the
community and various stakeholder groups.
The City engaged various stakeholder groups and the community through a series of
meetings, an on-line survey and public workshops. An overview of these efforts is
provided below.
➢ Stakeholder Interviews — September 2017
Various stakeholders, including members of the business community, Downtown
commercial property owners and City Councilmembers were engaged. The purpose
was to gain an understanding of their ideas, personal history, and experiences with their
property and the existing streetscape. Questions focused on what defines Downtown,
future objectives, identification of the Downtown's strengths and weaknesses and
discussions focused on what a successful streetscape plan could achieve.
y Open City Hall Online Survey — November 27, 2017 through January 5, 2018
Page 3of9
Packet Pg. 34
In an effort to find alternative ways to engage the community, an online survey was
distributed through the Open City Hall program. The six -week survey focused on the
Downtown as a social center. The survey included general questions on what makes a
social center as well as more specific question on the characteristics of Downtown
Dublin that help to create and also hinder the creation of a social center. The City
received 162 responses from the community.
➢ Community Workshop #1— December 2017
The first community workshop focused on gathering information on how the community
interacts with the Downtown and what improvements they would like to see. The
interactive presentation requested input on the streetscape character, circulation
patterns, areas most frequently visited, safety concerns, art themes and public spaces.
The community expressed interest in the following:
• Treating the identity of the Downtown as whole
• The need for a distinctive Downtown destination
• Village Parkway has the most potential to be the social center
• Improving bike and pedestrian safety and connections
• Making Downtown more walkable by improving pedestrian amenities,
lighting, and outdoor green spaces
• Incorporating art, lighting and banner to help provide identity
• Deciduous trees with fall color
• For planting, consider maintenance, recycled water requirements and
increased soil volume for healthy trees
➢ Community Workshop #2 — August 2018
The second community workshop solicited feedback on the following topics:
• The role and identity of each street, focusing on Village Parkway and
Regional Street
• Plantings and furnishings
• Green infrastructure approaches
• Signage/wayfinding /art
• Public open space
The community expressed interest in decorative street furnishings that were unique to
the Downtown moving away from a more standard bench design. Safety concerns
pertaining to bicycle circulation were presented which lead into a discussion regarding
additional bike lanes and calming measures on Amador Valley Boulevard. The
overarching theme in the community's comments were identity and the idea of creating
a unique identity for the Downtown through wayfinding signage, gateways and public
art.

The main sections of the document are described in more detail below.
Chapter 1: Executive Summary
This chapter establishes the vision and purpose of the Downtown Dublin Streetscape
Plan, its location and relationship to other plans and policies, and includes the
framework for implementation. As stated in the Downtown Dublin Streetscape Plan, its
purpose is to enhance the identity of Downtown Dublin as a destination, improve the
street experience for pedestrians, and create enjoyable places for people that support
community through participation in public life in shared space. It is also to create inviting
and attractive places that support Dublin's desirability and community life as land uses
change and properties are re -developed with new commercial, residential, and mixed -
use projects.
The Downtown Dublin Streetscape Plan characterizes Downtown streets into four
primary types: Crosstown Boulevards + Parkways, Commercial Throughways,
Downtown Local and The Core Streets. This framework informs the types of street
improvements which are most relevant, and which should be prioritized for each
Downtown street. The Plan also recognizes the incremental nature of improvements
and the need to implement improvements as opportunities arise. The improvements are
categorized into the following four tiers that can be matched to project scale, budget,
funding source, and other opportunities:
• Tier 1 — Small-scale, "tactical," temporary improvements or events including
painted crossings, parklets, street closers, temporary art and twinkle lights.
• Tier 2 — Middle -scale, piece-meal/a la carte, and opportunistic projects including
construction of gateway features, re -striping, mid -block crossings, tree
replacement, street furnishings and lighting.
• Tier 3 — Large scale, major capital improvement streetscape projects include the
redesign of Regional Street and Village Parkway
• Tier 4 — New Downtown public spaces which includes implementation of the
Town Square as provided in the Preferred Vision.
Chapter 2: Existinq Conditions
This chapter provides historic context for the Downtown Dublin Streetscape Plan area,
identifies the existing streetscape conditions as well as opportunities and constraints.
The chapter highlights Regional Street and Village Parkway as important opportunity
Page 5 of 9
Packet Pg. 36
streets to support to the transition of Downtown. Regional Street and Village Parkway 7'1
were identified as two streets that have the greatest opportunity to re -allocate street
space to support the needs of pedestrians and bicycles.
Chapter 3: Street Plans
This chapter focuses primarily on creating street space for people — reclaiming space
for a safe, expanded, pedestrian -oriented public realm and better accommodating
people traveling by bicycle and transit. The space and place -making opportunities
described in this chapter are supplemented by further definition of street identity
concepts and streetscape elements in Chapter 4.
More specifically, this chapter provides guidelines for all streets within the Downtown
including parameters for sidewalks, bulb -outs, mid -block crossings, re -striping, parklets,
and street closures.
Building off the existing conditions analysis in Chapter 2 and community input, this
chapter identifies redesigns of Regional Street and Village Parkway.
Regional Street: The redesign of Regional Street retains the existing curb
locations and re -allocates road space, removing the center turn lane except at
key driveways and intersections, and adding buffered bicycle lanes on each side
of the street (Figures 9 and 10). Two mid -block crossings are proposed.
Additionally, the plan increases the number of curbside parking spaces. It
provides bulb -outs along the length of the street for social gathering with seating,
art, and ornamental planting together with stormwater treatment. Improvements
on Regional Street must consider future bike access from bike lanes on St.
Patrick Way that will connect to businesses on Regional Street and then to San
Ramon Road. This change will be accommodated as land is redeveloped west of
Regional Street between San Ramon Road and Regional Street.
Village Parkway: The redesign of Village Parkway retains existing curbs and
sidewalks and targets improvements to specific areas (Figure 11). To improve a
sense of connection across the street, the raised median is lowered. It
recommends relocating trees and utilities to the back of curb to create a clear
path of travel for pedestrians in the sidewalk. Mid -block crossings are introduced
as are bulb -outs in locations where parking is not possible. Art, stormwater and
ornamental planting, and seating can be provided in the bulb -outs to encourage
pause and social gathering. This design will require a traffic study before it can
be considered for implementation.
This chapter also lays the framework for the Core Streets to create a unique place for
Downtown's main street. The Core Streets are defined by their generous sidewalks
creating a comfortable pedestrian realm that supports strolling, shopping, and dining,
neighborhood socializing, and events. The Core Streets will serve as an extension of
the Town Square in their ability to be closed off for pedestrian only events.
Chapter 4: Identity and Elements
Page 6of9
Packet Pg. 37
This chapter provides a conceptual identity and provides guidance and standards for
new streetscape elements including signage and wayfinding, art, paving, furnishings,
lights and trees. The identity in the Downtown Dublin Streetscape Plan builds from the
existing strengths including Dublin's stately trees, its public art, its signage which
expresses Dublin's "shamrock" brand identity, and recent streetscape improvements on
Golden Gate Drive. The identity also builds from the themes expressed by the
community at public workshops.
The last three chapters are included in the Appendix.
Chapter 5: Planning and Community Process
This chapter provides an outline of the outreach process undertaken as part of the
preparation of the Downtown Dublin Streetscape Plan. As provided in detail above,
outreach with the public, City Council, landowners, and business owners included: one-
on-one and small group stakeholder interviews, two community workshops, and online
surveys.
Chapter 6: Technical Information
This chapter provides the technical information for implementation of the Downtown
Dublin Streetscape Plan. Details regarding the installation of new and replacement trees
including tree species by street, sizing, soils, irrigation, and location. This chapter also
includes recommendations for the installation of green infrastructure and utilities. Green
infrastructure refers to a set of landscape and engineering techniques used to reduce
stormwater runoff and the square footage of non -porous material while cleansing
stormwater locally and alleviating flooding in downstream stormwater infrastructure.
Components of a green infrastructure system may include flow through planters and
permeable pavers. Recommendations for utilities focus on reducing their footprint
within the sidewalk and to limit their impact on the placement of trees and street
amenities. This will open up opportunities for trees and planting, creating a greener and
more sustainable street.
Chapter 7: Magnitude of Costs
This chapter provides estimates costs of the Tier 1, 2 and 3 improvements. Costs
provided are 2019 estimates intended to help prioritize the decision -making process and
are not intended to be used for construction budget purposes. Costs include labor,
materials, and overhead; however, utility replacement and relocation costs are excluded
from cost estimates.
Downtown Dublin Streetscape Plan Implementation
The improvements identified in the Downtown Dublin Streetscape Plan would serve as
a list of projects that could be used as part of the Community Benefit Program as well
as future City projects. In many cases, the new streetscape palette will be implemented
over time as existing improvements need maintenance or replacement, and the new
selection will be installed at that time. There are several recommendations contained in
the Downtown Dublin Streetscape Plan that will have cost implications at the time they
are implemented beyond the routine maintenance costs associated with replacing aging
equipment and/or facilities.
Page 7of9
Packet Pg. 38
The City Council may determine that some of the streetscape features be replaced on a
more aggressive timeline than the regular maintenance schedule. The City Council will
have the opportunity to make this decision as part of the budget process and to
determine when, and to what extent, these features will be funded.
Streetscape Master Plan Amendments
Minor amendments to the Streetscape Master Plan are necessary to clarify the
applicability of the Streetscape Master Plan and the new Downtown Dublin Streetscape
Plan. Only those recommendations and guidelines in the Streetscape Master Plan that
are specific to the Downtown area are proposed to the eliminated. Any which include
streets that extend beyond the Downtown will continue to apply. A copy of the
proposed amendments to the Streetscape Master Plan are included as Attachment 4
(Exhibit B of Attachment 2).
ENVIRONMENTAL REVIEW:
Staff recommends that the Downtown Dublin Streetscape Plan and amendments to the
Streetscape Master Plan be found exempt from the requirements of the California
Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15061(b)(3),
which exempts projects where it can be seen with certainty that there is no potential for
significant environmental effects. The Downtown Dublin Streetscape Plan does not
approve any development project or other physical activity; nor does it change any land
use or density designations that would affect development potential. Instead it provides
guidelines and standards through which streetscape improvements would be
implemented. Therefore, the Downtown Dublin Streetscape Plan itself has no potential
for resulting in significant physical change in the environment, directly or ultimately. Any
future improvements would be reviewed for compliance with CEQA.
NOTICING REQUIREMENTS/PUBLIC OUTREACH:
A notice of this public hearing was published in the East Bay Times and mailed to all
property owners and tenants in the Downtown Dublin Streetscape Plan area, those
within 300 feet of the existing Downtown Dublin Streetscape Plan boundaries, and all
persons who have expressed an interest in being notified of meetings. The notification
list for Downtown Dublin Streetscape Plan notices has 2,330 mailing addresses and
approximately 330 e-mail addresses. Announcements of each public meeting related to
the Downtown Dublin Streetscape Plan have been mailed and e-mailed to these
notification lists.
Numerous public outreach efforts have taken place over the course of developing the
Downtown Dublin Streetscape Plan, including an online survey, stakeholder
interviewers, and community workshops.
The Staff Report for this public hearing was also available on the City's website on a
specific "Downtown Dublin Streetscape Plan" webpage and posted on the City's
Nextdoor webpage.

Downtown Dublin Streetscape Plan
1.1 INTRODUCTION
1.1.1 Background
The City of Dublin City Council, City Staff and members of the Dublin community have been actively engaged in expanding the City's
efforts to create a cohesive, unique, and walkable destination Downtown. A number of planning documents focus on and guide the
redevelopment and reinvestment in the Downtown area as shown in Figure 1. These include:
1. Downtown Dublin Specific Plan, 2011 (amended in 2020)
2. ULI Technical Assistance Panel study, 2011
3. ULI Technical Assistance Panel study, 2018
4. Dublin General Plan, 1985 (amended in 2017)
5. Streetscape Master Plan, 2005 (amended in 2009)
6. Bicycle and Pedestrian Master Plan, 2014
7. Public Art Master Plan, 2020
8. Downtown Dublin Preferred Vision, 2019
The Downtown Dublin Streetscape Plan (the Plan) expands upon the recommendations contained in these documents in more detail as
they relate to the streetscape - improving the beauty, identity, and function of Downtown streets. The Plan provides further direction for
public and private investment, specifically in regard to the development of the public realm and Downtown's identity, with the intent of
creating a clear and unified look and feel for Downtown Dublin.
1.1.2 Vision and Purpose
Improved Downtown Dublin streets will enhance the identity of Downtown Dublin as a destination, improve the street experience for
pedestrians, and create enjoyable places for people that support community through participation in public life in shared space.
Creating inviting and attractive places will support Dublin's desirability and will support community life as land uses change and
properties are re -developed with new commercial, residential, and mixed -use projects.

1.1.3 The Plan
This document describes potential opportunities and proposed improvements from a variety of perspectives, scales and areas of focus.
The Executive Summary describes an overall Street Framework (1.2.1) that organizes and focuses improvement opportunities by street
type. Project Implementation Opportunities (1.2.3) provides a list of improvements based on scale, scope and effort, and identifies high -
impact, high -priority improvements.
In addition to providing urban context, the Existing Conditions (2.0) chapter describes the quality of existing street spaces and elements
and provides general opportunities and constraints that inform proposed improvements.
Chapter 3 and 4 present opportunities to enhance the identity and visual character of Downtown Dublin as well as the spatial qualities
of Downtown streets so that they function better for all, including, pedestrians, bicyclists, and transit riders.
The Street Plans (3.0) Chapter presents guidelines for expanding the pedestrian realm for people and include street -specific concept
plans for improvements to Regional Street and Village Parkway.
The Identity and Elements (4.0) Chapter presents guidelines for the overall look, feel, and "brand" that create the visual image of
Downtown Dublin's public realm, illustrates proposed unique elements for Downtown Dublin, and describes standard streetscape
materials and furnishings.
Lastly, the Appendix section provides a recap of the Planning and Community Process (5.0) and supplemental information to guide
decision makers, planners, designers, and developers as they contemplate and implement individual projects. Technical Information
(6.0) provides further detail on planting standards, green infrastructure, and utility coordination, while Magnitude of Costs (7.0) provides
order of magnitude construction costs for various improvements.
1.2 IMPLEMENTATION
1.2.1 Street Framework
The streets of Downtown Dublin can be characterized by the roles they serve related to the transportation system and to the land uses
adjacent to the streets. Informed by the Downtown Dublin Specific Plan, this Plan characterizes Downtown streets into four primary
types: Crosstown Boulevards + Parkways, Commercial Throughways, Downtown Local and The Core Streets as shown in Figure 2. This
framework informs the types of street improvements which are most relevant, and which should be prioritized for each Downtown street.

Downtown Dublin Streetscape Plan
Crosstown Boulevards + Parkways
These streets carry large volumes of traffic along significant north -south and east -west corridors. Typically, these streets carry multiple lanes
of traffic in each direction and may be softened by planted medians and side buffers. Crosstown Boulevards + Parkways include Dublin
Boulevard, Amador Valley Boulevard, and San Ramon Road.
Key goals for these streets are:
• Identity and Visibility - Reinforce a cohesive overall street identity while creating moments of interest and orientation to the
smaller Downtown streets through larger scale gateways, signage, art, and intersection paving treatments.
Traffic Safety and Comfort - Moderate the effects of high traffic volumes on bicyclists and pedestrians by expanding
pedestrian space and additional planting buffers.
Commercial Throughways
These streets are fronted by commercial uses including shopping, dining, and services. While they may carry significant volumes of traffic
and be a part of crosstown traffic, they are distinguished by the scale of the street and density of commercial uses that front them. These
streets include: Village Parkway and Amador Plaza Road.
Key goals for these streets are:
• Pedestrian -Scale Placemaking - Create a comfortable pedestrian realm that supports strolling, shopping, and dining.
• Traffic Safety and Comfort - Moderate the effects of high traffic volumes on bicyclists and pedestrians by expanding pedestrian
space and creating mid -block crossings.
Downtown Local
These shorter, smaller streets do not extend outside of the Downtown area. Like Commercial Throughways, they are predominantly fronted by
commercial uses that include shopping, dining, and services, but also include residential and mixed -uses. These streets include: Regional
Street, Golden Gate Drive, St. Patrick Way, and a small portion of Amador Valley Boulevard. Future Downtown Local streets are planned for
the Retail District creating a new grid pattern in the center of Downtown. These streets are intended to compliment and support the new
Town Square.
Key goals for existing and future Downtown Local streets are:
• Pedestrian -Scale Placemaking - Create a comfortable pedestrian realm that supports strolling, shopping, and dining,
neighborhood socializing, and events.
• Traffic Safety and Comfort - Design "slow streets" with an emphasis on bicycle and pedestrian infrastructure.
• Green Streets - Integrate generous space for trees, stormwater treatment, and "green infrastructure."
ILI
The Core
The Core streets implement the Downtown Dublin Preferred Vision and are comprised of the four blocks around the new Town Square to
create a downtown character with a synergy for a mix of uses to thrive. The extension of Golden Gate Drive from the BART station through
Downtown Core will become a new main street within a classic street grid.
Key goals for The Core streets are:
Pedestrian -Scale Placemaking - Create a comfortable pedestrian realm with generous sidewalks that supports strolling,
shopping, and dining, neighborhood socializing, and events.
• Traffic Safety and Comfort - Design "slow streets" with an emphasis on bicycle and pedestrian infrastructure.
Extension of the Town Square - Enhance the Town Square which has been designed with open space for activation where
everyone can see each other.
Specific examples of streetscape improvements related to these goals for the streets are shown on Figure 3 described in Project
Implementation Opportunities (1.2.3), Street Plans (3.0), and Identity and Elements (4.0).
Downtown Dublin Streetscape Plan
1.2.2 Funding and Implementing
The streetscape improvement opportunities described in the Plan will be
implemented incrementally via multiple parties and funding sources, including:
• Property Owner/Developer Requirements, Developer In -kind
• Community Benefit Program
• Capital Improvement Program
• Coordination with other public improvement projects and maintenance
activities
1.2.3 Project Implementation
Improvements to the public right-of-way, land use changes, and development are
related. New developments will create a more "urban" small-town and pedestrian -
friendly Downtown character — through uses that abut and activate the street. Change
will be incremental but guided by the vision of this and other Downtown planning
documents and initiatives. Recognizing the incremental nature of improvements, and the
need to implement improvements as opportunities arise, the Plan categorizes
improvements into the following four tiers that can be matched to project scale, budget,
funding source, and other opportunities:
• Tier 1 - Small-scale, "tactical," temporary improvements or events
• Tier 2 - Middle -scale, piece-meal/a la carte, and opportunistic projects
Tier 3 - Large scale, major capital improvement streetscape projects
• Tier 4 - New downtown public spaces
Within the list of improvements identified in Tier 1 and Tier 2, suggested high -impact
projects are identified, followed by secondary -priority projects. In some cases, within
improvement categories, recommendations are provided for where these types of
improvements should be installed first. Additional details on how these projects are to be
implemented are provided in the Guidelines provided in Street Plans (3.0) and Identity
and Elements (4.0).

Tier 1 Improvements
Tier 1 improvements do not require significant alterations to existing street infrastructure.
Sometimes described as "tactical urbanism," these "light" approaches include non-
permanent features such as paint, temporary and short-term installations and placemaking,
and events. This light approach may include "pilot" projects which are time -limited or
reversible that can be used to prototype, collect data and refine concepts, prove the
validity of, and build support for longer term improvements and more permanent physical
changes. Additionally, Tier 1 improvements can create a greater sense of Downtown as a
dynamic and changing place, encouraging, motorists, cyclists, and pedestrians, to slow,
stop, and participate in Downtown, and to support the daily life of a growing Downtown
community of businesses and residents. For further description and guidelines for these
elements, see Street Plans (3.0) and Identity and Elements (4.0). See Figures 3 and 4 for
recommended locations.

Downtown Dublin Streetscape Plan
Tier 2 Improvements
Tier 2 improvements target specific street improvements with less impact to existing
infrastructure and systems than a comprehensive street re -construction. Characteristics of
Tier 2 improvements include smaller projects that are more affordable, and for which
funding may be more readily obtainable, localized improvements that have a reduced
physical footprint and do not significantly change the configuration of existing curbs,
utilities, or other infrastructure or projects that involve no construction and are, thus, faster
to permit and install (tree plantings, banner replacements). Tier 2 improvements that also
include projects that benefit the public realm often move forward under the umbrella of a
larger project such as private development that necessitates upgraded sections of the
public right-of-way in front of their property and large infrastructure and utility projects that
provide an opportunity to add on targeted improvements to the streetscape.
The following streetscape elements and systems are examples of improvements which
could be installed individually or in combination as a Tier 2 improvement. For further
description and guidelines for these elements, see Street Plans (3.0) and Identity and
Elements (4.0). See Figures 3 and 4 for recommended locations.
Examples of Tier 2 improvements are provided below and grouped by suggested priority:

Tier 3 Improvements
Major streetscape capital improvement projects include the comprehensive re -design and
re -construction of streets, with opportunities to re -allocate street space — reclaiming "lost"
or underutilized space to enhance the street character and create pedestrian space. These
are long term projects that require significant planning, capital, and construction. They
often involve the redesign of multiple existing systems in order to achieve multiple public
improvement goals through a holistic design solution. Examples of significant system
adjustments include upgrading or reconstructing streets, curb relocation, utility replacement
or relocation, surfacing, and the reallocation of street space.
In conjunction with planning and redevelopment efforts, Tier 3 projects could be conducted
as major public works projects which could bring value to adjacent properties, spurring
private investment and redevelopment, and create the public infrastructure to create a
destination downtown main street.
Chapter 3.0 provides concepts for two potential Tier 3 projects — redesign of Regional Street
and Village Parkway.
• Regional Street improvements include re -allocation of roadway space between curb,
bike lane, street trees and planting, stormwater gardens, furnishings, paving, street
lighting, art, bulb -outs.
• Village Parkway improvements include bike lanes, street trees and plantings, site
furnishings, paving, street lighting, art, and bulb-out/curb extensions, green
infrastructure/stormwater gardens, and a gateway.

Conceptual images of Town Square from Downtown Dublin Preferred
Vision
Tier 4 - New Downtown Public Space / Gathering Areas
In both community meetings conducted for the Plan, the public expressed a desire to
provide Downtown with gathering spaces for children to play, people to meet and
relax, and events to take place. The City should evaluate possible Downtown sites that
can accommodate different types and sizes of public gathering areas at key
intersections along the primary travel corridors. These include Golden Gate Drive, Dublin
Boulevard, St. Patrick Way, Village Parkway, and Regional Street.
As part of the Downtown Dublin Preferred Vision, the City Council approved the siting of
a new Town Square; a one -acre park and plaza that will serve as Downtown Dublin's
primary gather place. The location of the Town Square is one block north of Dublin
Boulevard along the proposed extension of Golden Gate Drive. The four -block area
surrounding the Town Square referred to as "The Core" creates a downtown character
with synergy for a mix of uses to thrive. The streets within The Core are unique and
contribute to the vibrancy of the area. Chapter 3.0 provides the guidelines for The Core
streets.
Smaller scale public spaces such as neighborhood parks will be important for Downtown
Dublin as its residential population continues to grow. These spaces will strengthen the
sense of place, provide residents with outdoor space, and serve to promote pedestrian
and biking movement between Downtown destinations. Green spaces will help build a
connected community where residents can interact and come together for social
events. Once sites are identified, make temporary and affordable improvements such as
community tables, seating, and planting while permanent improvements are prepared.
When complete, the park should feel part of the neighborhood, festive in nature, and
provide space for active and passive uses.
At the smallest level, provide sheltered seating areas along all circulation networks to
activate Downtown connections. Provide directional signage, seating, planting, and
interpretive elements at gathering areas to assist in navigation.

2.1 URBAN CONTEXT
The City of Dublin grew up around the crossroads of two major trading routes - one
running north -south between Martinez and San Jose and the second moving east -west
between the Bay Area and Stockton - located approximately near the intersection of San
Ramon Road and Dublin Boulevard. While the small settlement of Dublin was bypassed by
the railroads, the small town rapidly expanded after World War II, incorporating in 1982.
Consequently, the texture of Dublin's urban fabric is typical of post -World War II suburban
development, characterized by single-family homes, automobile -oriented commercial
areas and wide streets. Downtown Dublin generally consists of large block sizes with
parking lots fronting the streets, wide streets, large building footprints, and expansive
parking lots, which foster an environment dominated by automobiles.

Downtown Dublin Streetscape Plan
2.2 OVERALL STREETSCAPE CONDITIONS
Space Allocation
The land use character and supporting street network in Downtown Dublin is predominantly designed for motor vehicles. It includes large
empty parking lots at the back of sidewalks, multiple driveways to the parking lots, and many wide multi -lane streets (Dublin Boulevard,
San Ramon Road, and Amador Valley Boulevard) that carry a high motor vehicle traffic volume. Where these streets meet, intersections
are large and often include multiple dedicated turn lanes, and right -turn slip lanes (or "pork- chops"). These intersection configurations
and the land use character are designed for traffic flow and circulation of auto traffic and might not fully integrate multimodal access for
pedestrians and cyclists. Of the three retail -oriented streets (Village Parkway, Regional Street, and Amador Plaza Road) that run north -
south between Amador Valley Boulevard and Dublin Boulevard, the block lengths are long with few store fronts at the back of the
sidewalks, and multiple driveways that give limited pedestrian comfort and crossing opportunities. Compounded with narrower sidewalks,
non-existent interaction of public space with business frontages, and street furniture (utility poles, newspaper racks, benches, etc.) in the
path of travel, the environment does not encourage pedestrian movement and comfort. On several streets, street trees have been
planted at the back of sidewalk rather than behind the curb due to store fronts not connected with the sidewalks and where they would
provide a buffer between pedestrian path -of -travel and fast-moving traffic. Along the streets, bicyclists and pedestrians will encounter
multiple driveways to large parking lots that interrupt their movement and comfort, and also limit opportunities for trees and other
amenities. Some bikeways are disconnected. In these locations, Class III bikeways shared with vehicles are provided to close a gap in the
Class II striped bike lane network where the right-of-way is restricted. Some of the gaps in the bike network are planned to be
implemented per the City of Dublin's Bicycle and Pedestrian Master Plan.
Street Character
The character and quality of Downtown streets varies. Strong features include the recently improved Golden Gate Drive where abutting
land uses were moved to the back of the sidewalks by removing large parking lots, Dublin Boulevard "shamrock" identity elements, public
art, and mature trees in a variety of locations. However, as a whole, the Downtown streets lack an overall cohesive identity and quality.
Throughout Downtown, street materials and furnishings such as paving, streetlights, benches, trash receptacles, and bus shelters are
inconsistent and vary in design and age. Several streets benefit from a strong street tree presence, though many trees are aging, some
species are prone to disease, and others lack a memorable visual presence. Sections of other streets on San Ramon Road, Amador Plaza
Road, and St. Patrick Way have few trees or none at all. On many streets, street trees are located at the back of sidewalk, and wide
setbacks of parking or landscaping between the building and street results in streets that feel uncontained and overly wide. In most places
Downtown there is a lack of connection and interaction between building uses and the public realm. This, together with the lack of visible
and significant social spaces within the pedestrian realm limits opportunities for Downtown "street life" such as dining, gathering, strolling
and promenading.
011
Downtown Dublin Streetscape Plan
Existing Trees
Many parts of Downtown Dublin contain large, mature, broad -canopy, deciduous street
trees which contribute to the aesthetics of Downtown while providing shade, energy
conservation, temperature control, and health benefits such as reduced air pollution and
stress mitigation. Key issues for existing street trees:
• Older trees need to be replaced over time.
• Time required to maintain and care for trees increases with the age of the tree.
• A limited number of species are used. This increases the potential for tree loss to
disease and impacts to the Downtown's appearance.
• Trees located on the private property side do not buffer pedestrians from street traffic.
Streetscape Elements and Systems
As noted above, streetscape and district character is in large part defined by the
surrounding land uses and the visual quality and continuity of the following streetscape
elements and systems within the right-of-way: trees and planting; lighting; paving; furnishings;
signage and wayfinding; and art. As Downtown Dublin's streets have been developed and
modified over the years, the existing elements and systems are mixed in visual character.
Adding additional complexity are existing utilities that extend the length of roadways and
laterally across sidewalks. Finding adequate space for all street improvements is a
challenging endeavor. Redevelopment provides an opportunity to reshape the street to
enhance the user experience and improve sustainability.
Trees and planting: The most common trees found in Downtown are London plane, crape
myrtle, and pear trees. Other trees used less frequently include Chinese pistache,
camphor, pink dawn, ash, purple leaf plum, strawberry tree, and eastern redbud.
Lighting: Cobra head roadway lighting on widely spaced, painted, and galvanized poles is
typical throughout the Downtown. Village Parkway is lined by a separate, decorative,
pedestrian scale streetlight pole with twin upright fixtures. Golden Gate Drive has its own
decorative, modern style pedestrian streetlight fixture.
Paving: Sidewalks typically consist of standard concrete paving. On Village Parkway,
special paving is composed of paver bands, while on Golden Gate Drive widened bands
of pavers were recently installed. San Ramon Road also includes a sinuous asphalt bike
and pedestrian path on the western side of the street. Medians use concrete pavers to
provide a maintenance strip around planting and fill in segments where the median tapers
and narrows to accommodate turning lanes.

Furnishings: Furnishings differ across Downtown. Dublin Boulevard, Village Parkway, and
Golden Gate Drive each have their own palette with older furnishings present while the
remaining streets have few furnishings. Bus shelters vary in design including two shelters
installed on Amador Valley Boulevard designed as public art pieces.
Signage/Wayfinding: On Dublin Boulevard, special identity and wayfinding signage
where designed with brown structural frames with a green metal shamrock pattern
integrated into the middle of the frame. Identity signs are located in the median and
include bronze letters and shamrocks mounted on the frame highlighting the City of
Dublin as well as the neighborhood district. Wayfinding signs located in sidewalks include
arrows and destinations.
Art: Art in or visible from the public right-of-way in Downtown Dublin includes a mix of types
and themes - from murals depicting Dublin history, to more contemporary stainless -steel
furnishings such as a clock and bus shelters.
Green infrastructure: With the exception of stormwater treatment planters installed as part
of the recent Golden Gate Drive improvements, most stormwater on Downtown streets is
not treated before entering the storm drain system.
Existing Art
Downtown Dublin currently has seven works of public art in or visible from the public right-
of-way, of which four pieces are installed as part of private development. These include
the following pieces below and shown on the right:

2.3 EXISTING CONDITIONS ON REGIONAL STREET AND VILLAGE PARKWAY
Regional Street and Village Parkway were identified as two streets that have the greatest opportunity to re -allocate street space to
support the needs of pedestrians and bicycles. Of the three retail -oriented streets (Amador Plaza Road, Regional Street and Village
Parkway) that run north -south, Regional Street and Village Parkway are characterized by long block lengths with only one pedestrian
crossing opportunity combined. Both streets have their unique challenges but offer a variety of commercial land uses and underutilized
space within the rights -of -way. The redesign for these streets is provided in Section 3.3 Regional Street and Village Parkway Alternatives.
2.3.1 Regional Street
Existing Conditions
Regional Street extends south from Amador Valley Boulevard and terminates in a cul-de-sac south of Dublin Boulevard, near the St.
Patrick Way extension. One residential community and a variety of commercial land uses are adjacent to Regional Street, including
restaurants and cafes, retail, entertainment, services, and hotel. Buildings are set back and have a poor relationship to the street, though
in some instances restaurants have outdoor dining facing the street.
North of Dublin Boulevard, the typical street cross section includes center turn lane, travel lane in each direction. Large portions of the
street are striped to prohibit parking, resulting in very wide, unused road space. Parallel parking is provided along the street in a few
locations, though off -site parking is plentiful in adjacent lots. Sidewalks are approximately eight -foot wide on each side with street trees
occurring at back of curb in different sizes of tree openings. Between Dublin Boulevard and Amador Valley Boulevard (approximately
1,100 feet), there are no demarcated crossings.

South of Dublin Boulevard, except for the intersection with Dublin Boulevard, street travel
lanes are not striped. However, the approximate 51-foot curb to curb dimension
generously accommodates one travel lane in each direction as well as on street parking.
Sidewalks are approximately eight -foot wide on each side with street trees occurring at
back of curb in three-foot by three-foot tree openings. Fire hydrants located at back of
sidewalk present obstacles to the flow of pedestrian movement.
No bicycle facilities are provided on Regional Street, though the street is planned as a
bicycle route in the Bicycle and Pedestrian Master Plan.
Downtown Dublin Specific Plan
North of Dublin Boulevard, Regional Street falls within the Retail District of the Downtown
Dublin Specific Plan (DDSP). The Retail District is envisioned to be a pedestrian -scale,
walkable environment with businesses including a mix of retail (ranging from small
independent retailers to national regional -serving retailers), service, office, and civic.
South of Dublin Boulevard, Regional Street falls within the Transit -Oriented District of the
DDSP. Land uses envisioned include mixed -use such as office or residential above ground
floor retail, high -density multi -family residential, and office uses with a pedestrian -scale,
walkable environment that is more urban in character than the surrounding area.

2.3.2 Village Parkway
Existing Conditions
Within the project area, the segment of Village Parkway between Amador Valley Boulevard and Dublin Boulevard is fronted by a wide
variety of commercial uses, including dining, retail, and services. In contrast to other areas within Downtown, Village Parkway is fronted by
a greater density of businesses with store fronts at the back of the sidewalk, many of which are smaller in scale and independently
owned. The street is punctuated by numerous driveways serving parking areas. Segments of Village Parkway have parking on both sides
(23 spaces on the west side and 19 spaces on the east side). Some of the curb is striped red to provide visibility and safety for access -
and results in an unused roadway space that gives a perception of a wider street. A raised center median increases the sense of division
across the street and a main utility line overhead runs down the center of the street. Crossing of the street is reserved to the intersections.
Pedestrian street crossings are inconvenient - crosswalks occur at intersections 760 feet and 880 feet (approximately three min. walk)
apart.

points and providing no buffer from cars.
Downtown Dublin Specific Plan
Village Parkway is located within the Village Parkway District of the DDSP. The Village
Parkway District is envisioned to be a pedestrian -scale, walkable environment with diverse
and complementary land uses. The district should incorporate live/work units and possibly
high -density housing if an appropriate site is identified.

2.4 OPPORTUNITIES AND CONSTRAINTS
The existing conditions present the following general opportunities and constraints for
Downtown streets. More specific opportunities and constraints are described in Chapter 4 -
Street Plans.
General Opportunities:
• Reclaim "lost" / under-utilized, and over -sized vehicular spaces for more
pedestrian oriented uses.
• Within the sidewalk, establish clear zones for pedestrians and furnishings that
include a step -out zone from curbside parking and a frontage zone for
businesses (Figure 7).
Build and expand on Dublin's existing public art and signage identities - the
shamrock icon, Dublin history, and more modern works.
• Address the frontage zone with streetscape improvements. Businesses need to
move to the back of the sidewalk with implementation of the DDSP.
Create a classic street grid through implementation of the Downtown Dublin
Preferred Vision
General Constraints:
• Utility relocations that require time for coordination and implementation and
have a high cost.
Timing of land use changes and developments with Downtown property
owners.
Physical dimensions of streets and managing impacts of changes with
existing vehicular traffic volumes.

Downtown Dublin Streetscape Plan
Downtown is poised to become more vibrant through the addition of new housing, retail, commercial, and mixed -use development. The
intent of the street improvements is to create better downtown places for people. Downtown streets should encourage people to move
more slowly, and to interact more fully with their surroundings and with one another.
This chapter focuses primarily on creating street space for people - reclaiming space for a safe, expanded, pedestrian -oriented public
realm and better accommodating people traveling by bicycle and transit. The space and place -making opportunities described here are
supplemented by further definition of street identity concepts and streetscape elements in the following chapter.
3.1 EXPANDING THE PEDESTRIAN REALM
Expanded pedestrian space is needed along sidewalks, at intersections, and at mid -block crossings. Figure 3 in the Executive Summary
(1.0) shows opportunities for street space improvements throughout Downtown. General sidewalk space recommendations for all
Downtown streets include:
• Where possible, expand Downtown sidewalk widths on Crosstown Boulevards + Parkways, Commercial Throughways, and
Downtown Local streets to a typical 12-foot minimum to create a generous Downtown pedestrian realm for strolling, shopping,
dining, and socializing.
• Urban Frontage (buildings located at back of sidewalk) - Provide a minimum 12-foot sidewalk, curb to face of building. A
portion of sidewalk may be on private property.
• Commercial Frontage - Provide a 12-foot minimum sidewalk. The sidewalk should include a furnishing zone with tree grates,
streetlights, street furniture, as well as a minimum five to six-foot clear throughway zone for walking.
• Dublin Boulevard - Provide a minimum 15-foot bike and pedestrian trail (five-foot tree zone and ten -foot path).
• Sidewalk widths are subject to change once each street is looked at more closely with the City's long-term goals.
3.2 STREET PLAN GUIDELINES
Guideline 3.2.1 Sidewalk Zones
Organize the sidewalk to limit and buffer interaction with vehicles, create a clear and direct walking route, and create spaces for
socializing and activating the streetscape. Proposed zones for expanded sidewalks (Figure 8) include:
• Flexible Frontage Zone - Located adjacent to the property line (up to two feet) or in the private set back to support outdoor
dining, and seating. (Not required)
• Through Zone - Provide continuous clear walking zone (five feet minimum).
• Furnishing Zones - Locate trees and utilities at back of curb to provide adequate space for street furnishings, plantings, and
other amenities and pedestrians with a pleasurable and unhindered walking experience (five feet minimum).
• Step -out Zone - Provide a clear zone adjacent to parking, where it occurs (required, two feet minimum).
31
Downtown Dublin Streetscape Plan
Guideline 3.2.2 Bulb -outs
Bulb -outs provide safety for pedestrians by reducing street crossing distances and are
typically located at intersections and mid -block crossings. Bulb -outs may also be
located along a sidewalk in place of a parking space or to narrow an overly wide
roadway to expand the pedestrian realm. The space created in the bulb -out can
provide for a combination of seating, art, stormwater planters or ornamental planting.
These components together improve the visual appearance of a street, making it an
inviting place to walk. Bulb -outs are recommended at all intersections, especially larger
intersections on the Crosstown Boulevards + Parkways.
Guideline 3.2.3 Mid -block Crossing
Mid -block crossings provide pedestrians with opportunities to shorten the street crossing
distances and to increase safety. In addition to existing mid -block crossings on Amador
Plaza Road and Amador Valley Boulevard, add two mid -block crossings first on
Regional Street and then on Village Parkway. Mid -block crossings should include bulb -
outs that provide opportunities for a combination of ornamental planting, stormwater
planting, social seating, and art. Crosswalks should include special paving that
increases pedestrian visibility and encourages vehicles and cyclists to proceed at a
reduced speed.
Guideline 3.2.4 Roadway Enhancements "Re-striping/"Road Diet"
Where possible on streets with wide travel and parking lanes, redistribute roadway
space by restriping the lanes and parking. Use the saved space to provide bike lanes,
buffers for existing bike lanes, or sidewalk expansions. Improve bicycling experience by
providing dedicated lanes or cycle tracks and limit the sharing of space with
pedestrians and vehicular traffic. At intersections and mid -block crossings, stripe
crosswalks to be more visible, improving safety for pedestrians crossing the street.
Example of a raised mid -block crossing

Example of an expanded sidewalk
Downtown Dublin Streetscape Plan
Parklets expand the sidewalk and create social spaces
Street closures provide opportunities for events that attract people
from nearby and regions beyond
Guideline 3.2.5 Enhanced Intersections and Crosswalks
Short -Term/ Temporary - Street painting treatments such as graphics painted across entire
intersections can create a high -impact visual "gateway." Paint, along with other
temporary elements (such as flexible bollards or planter pots), can be used to create
pedestrian space in the form of sidewalk "bulb -outs" or mini -street plazas where curb
changes would not be immediately feasible.
Long -Term - Establish a design that can be used in all crosswalks to help make them
highly visible, improve pedestrian safety, and tie into an art theme throughout
Downtown. At intersections identified as gateways, expand the artwork across the entire
intersection using a patterned design reflective of the City of Dublin. This design could be
applied with paint, stamped asphalt, or thermoplastic. Its scale and appearance will
signal to visitors and residents that they have moved within the boundaries of the
Downtown district. The design should be considered public art as created by the Public
Art Master Plan and would be subject to a selection process.
Guideline 3.2.6 Parklets
Parklets expand a sidewalk through re -purposing a parking space or stretches of red -
striped curb. In these parklets, creative seating, tables and chairs, planting and art can
improve the pedestrian experience and the visibility of businesses within the district.
Installations near coffee houses or restaurants are ideal locations for parklets.
Guideline 3.2.7 Street Closures
Working together with the City to ensure a safe event, adjacent property owners, groups,
or individuals can request that a street be temporarily closed for a special event. Such
events include neighborhood block parties, food trucks, music events, art fairs, farmers'
markets, and many others. In Downtown Dublin, The Core streets and St. Patrick Way
between Golden Gate Drive and Regional Street provides an excellent location to host
such events given its existing low traffic volume and close proximity to BART and the retail
centers. Other examples of the many street closures around the Bay Area include San
Francisco's Play Streets and Sunday Streets, Oakland Museum's Friday Nights, and
weekend Farmers' Markets in Burlingame and Berkeley.

3.3 REGIONAL STREET AND VILLAGE PARKWAY ALTERNATIVES
Two streets, Regional Street and Village Parkway were studied in greater depth and alternatives developed which re -allocate street
space to create space that supports the needs of pedestrians and bicycles and which creates space for improved public amenities
such as art, wayfinding signage, gateways, furnishings, and plantings. The alternatives maintain the existing right-of-way width. If, in the
future, additional right-of-way is required it shall be allocated to widening the sidewalk.
3.3.1 Regional Street
The redesign of Regional Street retains the existing curb locations and re -allocates road space, removing the center turn lane except at
key driveways and intersections, and adding buffered bicycle lanes on each side of the street (Figures 9 and 10). Two mid -block crossings
are proposed. Additionally, the plan increases the number of curbside parking spaces. It provides bulb -outs along the length of the street
for social gathering with seating, art, and ornamental planting together with stormwater treatment. Improvements on Regional Street
must consider future bike access from bike lanes on St. Patrick Way that will connect to businesses on Regional Street and then to San
Ramon Road. Accommodate this change as land is redeveloped west of Regional Street between San Ramon Road and Regional
Street.
Upgrade furnishings, paving, and lighting per Chapter 5.0. Integrate art in the social spaces and at intersections. At intersections, provide
bulb -outs where possible, to reduce crossing distance and improve safety for pedestrians. At these locations introduce green
infrastructure stormwater best practices. Main driveways may require a short turn lane. To accommodate them, remove parking
adjacent to the driveways to provide space for the turn lanes.
Opportunities
• Street parking maximized
• Bike lanes
• Introduction of mid -block crossings
• New bulb -outs in areas along curbs currently striped red
• Trees at back of curb
• Paving improvements
• Future potential four -foot + sidewalk expansion on

3.3.2 Village Parkway
The redesign of Village Parkway retains existing curbs and sidewalks and targets improvements to specific areas (Figure 11). To improve a
sense of connection across the street, the raised median is lowered. It recommends relocating trees and utilities to the back of curb to
create a clear path of travel for pedestrians on the sidewalk. Mid -block crossings are introduced as are bulb -outs in locations where
parking is not possible. Art, stormwater and ornamental planting, and seating can be provided in the bulb -outs to encourage pause and
social gathering. This design will require a traffic study before it can be considered for implementation.
The changes include an update to the street tree planting using proposed Columnar Hornbean, Red Maple and Eastern Redbud trees,
an upgrade of furnishings, paving, and lighting per Chapter 5, and integrated art in the social spaces and at intersections. Where
possible, provide bulb -outs at intersections to reduce crossing distance and improve safety for pedestrians. At these locations, introduce
green infrastructure stormwater best management practices. At the intersection with Dublin Boulevard, evaluate an arched gateway
together with enhanced paving improvements at both Amador Valley Boulevard and Dublin Boulevard (see Section 5.1 - Signage +
Wayfinding).

3.4 THE CORE STREETS
A key component to the Downtown Dublin Preferred Vision is the new street grid of public and private streets that provide a traditional
downtown format. The street grid provides a unifying framework that integrates varied activities and amenities into a coherent district.
The Core streets are a key component in this framework and are comprised of the four blocks around the Town Square. The extension
of Golden Gate Drive from BART through Downtown will become a new main street within a traditional street grid.
3.4.1 Design
The Core Streets are defined by their generous sidewalks creating a comfortable pedestrian realm that supports strolling, shopping,
and dining, neighborhood socializing, and events. The Core Streets will serve as an extension of the Town Square in their ability to be
closed off for pedestrian only events. The design details create a unique place for Downtown's main street.

Downtown Dublin Streetscape Plan
Streetscape elements are the materials and features that compose a streetscape
(e.g., paving, furnishings, planting, etc.). In addition to serving a functional purpose,
the design and palette of these elements are means to express the Downtown
identity. This section provides a conceptual identity and provides guidance and
standards for new streetscape elements.
4.1 IDENTITY
An improved identity for Downtown Dublin will build from existing strengths - Dublin's
stately trees; its public art; its signage which expresses Dublin's "shamrock" brand
identity, and recent streetscape improvements on Golden Gate Drive. The identity will
also build from the themes expressed by the community at public workshops - the
desire for urban vibrancy, bold design statements, distinctive and artistic elements,
places for socializing and gathering for all ages, incorporation of play, and decorative
night-time lighting. The Downtown streetscape identity will further support the City's
brand as "The New American Backyard" - a diverse, forward looking city, with a
relaxed atmosphere that is unpretentiously ambitious and casually sophisticated.
Design motifs that support this identity are:
• Color:
Warm browns, vibrant yellows and gold that express comfort and energy
Greens, that express nature and the City's "Irish" identity
Metallic / silver that expresses a future orientation
• Episodic use of bold, bright accent colors in planting, and temporary features
that express artful, urban liveliness and transformation
• Patterns and textures: Celtic knot patterning, Irish tartan/plaid, and textures,
but with modern materials and variation, expressing layering of influences and
connectedness

monument entry markers in Burlingame
4.2 SIGNAGE + WAYFINDING
Guideline 4.2.1 Gateways
Use gateways to direct and welcome people to the Downtown district. Gateways
elements such as arches or identifiable markers at primary entry points will signal to
residents and visitors that they have arrived in Downtown Dublin.
An arch is recommended across Amador Plaza Road. In other locations, consider the use
of gateway monuments if spanning the street is not feasible. Other gateway
improvements are recommended at the intersection of St. Patrick Way and the 1-680
offramp and on Dublin Boulevard at the intersection of San Ramon Road and may require
collaboration with Caltrans.
Example of conceptual gateway pylon
U-
Downtown Dublin Streetscape Plan
4.2.2 Wayfinding
Dublin Boulevard has an existing signage and wayfinding system that uses monuments
composed of shamrock cutout panels. Building off this shamrock design new
Downtown sign standards that incorporate the shamrock in a unique way can be used
on all Downtown streets to provide additional direction to help drivers, pedestrians, and
cyclists easily navigate Downtown and arrive at their destination. Wayfinding and
signage areas of improvement include:
Connections
Destinations that require better directional signage and safer links include the Iron Horse
Trail, connections under the freeway, BART, and destinations beyond the limits of the
Downtown district.
Bicyclists and Pedestrians
Signage for bicyclists and pedestrians should include directions to trails, public
restrooms, and drinking fountains.
Retail
In key locations around the main retail streets, add pedestrian wayfinding signage
to orient people to shops, dining, entertainment, and transit.
Street Signage
The shamrock shall be integrated into street name signs throughout Downtown.

Existing wall mosaic as storytelling
4.3 ART
Through art, Dublin can tell a story about its history and values, the environment, and
how the community sees itself in the future. Building on Downtown's existing public art
pieces, the City has an opportunity to turn Downtown into a destination that gratifies,
educates, inspires, and uplifts its community.
This plan identifies potential themes, locations, and types of art that would enhance the
streetscape. Currently, the City requires all capital projects and private developments to
reserve a portion of a project's budget for public art and the City's Public Art Master
Plan describes the existing programs, policies, and guidelines. Art elements included as
part of streetscape improvement projects would be subject to a selection process
determined by the City and consistent with the Public Arts Master Plan.
Proposed Art Locations and Installation Types
Locate art in a manner that it is accessible and visible to the public. Prominent locations
will increase appreciation of the art and make its location a destination that people will
be encouraged to visit, stop, ponder, and with which they will want to interact. Such
places can include intersections, plazas, medians, transit stops, and within the sidewalk.
Locating seating nearby helps give the public a place to pause and appreciate the art.
Vary the medium and scale of the art throughout Downtown to provide a range of
sensory experiences, whether from afar or up close. Possible art and gateway locations
and installation methods could include the following:
In the ground - Make use of the sidewalk surfaces to install historical plaques, mosaics, art
walk, art as historic markers, or other two-dimensional artworks. Locate these near transit
stops, seating areas, and places where people pause and will have ample opportunity to
enjoy them.
In the median - Install larger art pieces such as sculpture or kinetic art that can be
enjoyed by people crossing the street while pausing in median refuge islands. It may also
be appreciated by those traveling by vehicle and by people on nearby sidewalks. Avoid
blocking viewsheds near pedestrian crossings.
On the sidewalk - Similar to medians, artwork can also be installed in the furnishing zone
within the sidewalk. Ensure that the art does not impede pedestrian movement, car
parking, utilities, and sight lines near driveways and intersections.
Downtown Dublin Streetscape Plan
Walls - Art installed on walls provides an opportunity to tell stories using, for example,
murals and mosaics. It is possible to create wall art that allows for public interaction
and social media appeal. This art approach would help give Downtown a social
media presence.
Art benches -Install colorful art benches with a shamrock pattern, distinct from the
standard Downtown bench, throughout the Downtown district. These benches should
be comfortable and ADA compliant.
Art bike racks - Where space permits, consider the installation of art bike racks that are
whimsical and colorful. These could be designed in the shape of the Dublin shamrock.
These bike racks should also be secure and functional.
Kinetic - Art that responds to the natural elements whether wind, sun, seasons,
movement or other is a successful way to activate spaces. Kinetic art could highlight
sustainable energies and generate energy used to power nearby art, lighting, or
signage features.
Utility box art - Continue to wrap art around utility cabinets. Consider working with an
artist and schools to allow children to participate in the design process. Continue to
integrate the shamrock and explore other designs, similar to the playful appearance
of utility cabinets in Oakland and other Alameda county cities.
History - Incorporate art that interprets Dublin's history, such as the crossroads of Dublin.
Other options include art that educates the community about respected and famous
people that have come from or influenced the story of Dublin.
Underpasses - Continue to maintain and upkeep the murals underneath Interstate 680.

Example of herringbone paving pattern in a median.
4.4 PAVING
Pavement replacement can take place incrementally as improvements are made to
private parcels or public infrastructure in the right-of-way. With a paving material selected,
future paving replacement is to reflect it. As more paving is installed, its appearance will
become more continuous and legible, helping to identify the limits of Downtown Dublin.
Install paving replacement in the median and behind the curb in the sidewalk furnishing
zone and throughway as well as intersection corners and bulb -outs where planting is
absent.
Guideline 4.4.1 Sidewalk Paving
Sidewalk paving patterns and colors are inspired by the recent improvements on Golden
Gate Drive. Based on the extent of the improvements, install sidewalk paving as follows:
Use City Standard concrete mix with 1-1.5 pounds of Lampblack, introducing
interlocking concrete pavers (permeable, where possible) in accent bands every 3C
feet, similar to Golden Gate Drive. Bands are to be eight -feet wide and should extend
from the back of curb to back of sidewalk.
When possible, implement sidewalk paving improvements on an entire street basis. When
smaller segments of a street sidewalk are improved, study the adjacent existing
conditions. If accent pavers are already present, continue the pavers using the 30-foot
spacing to create an identifiable rhythm along the entirety of the street.
Guideline 4.4.2 Median Paving
Use a four -inch by eight -inch permeable paver in a herringbone pattern within the
median. The color is to be similar to the dominant color proposed in the sidewalk. Provide
a 20-inch paver strip around planting for maintenance that is retained with an edge
restraint. In medians less than 12 feet wide, eliminate pavers and use a walkable planting
groundcover.
50
Downtown Dublin Streetscape Plan
4.5 STREET FURNISHINGS
The following furnishing guidelines provide consistency throughout the Downtown.
Materials have a contemporary appearance in form and material. Consider "art"
furnishings to create spontaneity and to add vibrant colors (see Section 5.2). The
furnishings listed below are all pre -approved and may only be substituted with a similar
design upon approval of the Community Development Director and Public Works
Director.
Guideline 4.5.1 Seating
Bench, typical - The typical bench should have a modern appearance and
incorporate wood and a metal frame. The bench should include a back and armrests
at the bench ends. Wood is to be unfinished, durable, and sustainably harvested.
Approved bench is manufactured by Generation 50 with Jarrah wood and black
powder coated legs.
Art bench - Design an art bench for the Downtown district that is whimsical, ADA
compliant, and that varies in paint color throughout the Downtown. The bench could
be customized to include shamrock motifs. Install art benches in locations with greater
visibility and pedestrian movement including mid -block crossings, gateway
intersections, and near BART.
Bench lengths will vary based on available space. An ideal layout would have
benches face each other perpendicular to the curb to encourage social interaction
with four to five feet of space between benches. Where space is insufficient in the
furnishing zone (see Figure 2 - Sidewalk Layout in Chapter 2), run benches parallel to
the curb in the furnishing zone, facing the building rather than the street to participate
in pedestrian street life rather than the busy traffic in the roadway. Provide a minimum
2-foot clearance between the face of curb and the back of bench, regardless of
orientation. Set benches back a minimum of 18 inches from the pedestrian
throughway when installed parallel to the street. As street seating layouts are
designed, provide a minimum 30-inch by 48-inch clear zone adjacent to benches for
wheelchairs. A majority of benches installed are to have back support, armrests, and
seat heights between 17 to 19 inches.
Guideline 4.5.2 Bike Racks
Bike racks are to be a shamrock -shaped, have two points for locking, and meet the
design guidelines of the Bicycle and Pedestrian Master Plan. Colors are to vary
throughout Downtown. The custom bike rack is available from Dero.

Guideline 4.5.3 Trash and Recycling Receptacles
Provide black powder coated recycling, trash and compost receptacles throughout the
Downtown at intersections and mid -block crossings. Recycling receptacle is to be single
stream. Receptacles are to be clearly labeled to communicate the desired waste stream.
Trash receptacles are to have wide -mouthed openings to accept larger pieces of trash.
Approved receptacles are manufactured by Dispatch by Forms + Surfaces.
Guideline 4.5.4 Tree Grates
Tree grates are to be powder coated black matte and are to match those already in use
in the Downtown (Kiva by Urban Accessories). These should measure four feet by eight
feet and only be smaller (16 square feet, minimum) if constrained by space. Grates are
to be ordered with a center opening expansion of a minimum two feet, six inches to
reduce long term maintenance issues when the tree trunk expands. Toaccommodate
tree stakes, knock -outs are to be provided with cover plates to screw into holes when
stakes are removed. Provide a minimum of two stakes and three stakes where subject to
high winds.
Guideline 4.5.5 Bus Shelters
Retain the existing Public Art Bus Shelters on Amador Valley Boulevard. With the
exception of Rapid Bus shelters which are Tri Valley wide, replace all old bus shelters with
the new City/LAVTA City standard bus shelter. Coordinate with LAVTA for changes to bus
shelters.

Downtown Dublin Streetscape Plan
4.6 STREET LIGHTING
Street lighting plays an important role in the identity of a district. Similar to trees,
streetlights are a memorable vertical element that create a visible rhythm when spaced
appropriately. When poles are spaced too far apart, their rhythm is broken by myriad
competing visual elements in the surroundings. Furthermore, streetlights provide an
opportunity to clearly brand a district through the use of a distinctive decorative pole
with banners hung from the side. Incorporate alternating roadway and pedestrian -
scaled poles. On the backside of roadway poles, provide pedestrian scale fixtures at the
same height as the fixtures on pedestrian poles to safely illuminate the sidewalk path of
travel. Roadway poles should be strong enough to support a catenary system running
overhead banners or lights across intersections as well as comply with fire code height
requirements. On Commercial Throughways, Downtown Local streets, and at
intersections, provide poles with GFI receptacles for event power in the base. To limit light
pollution, light fixtures are to be full cut-off fixtures and LED. Poles and fixtures are to be
powder coated (RAL color to be determined). Retain the recently installed streetlights on
Golden Gate Drive to reduce waste and costs.
Prioritize Commercial Throughways, then Downtown Local streets, and finally Crosstown
Boulevards +Parkways. Street lighting improvements are encouraged to be reviewed
and installed on a block -by -block to provide a uniform, safe, and consistently lit street.
Guideline 4.6.1 Roadway Lighting
In the median, provide a twin head model. In the sidewalk, provide a roadway
fixture facing the street and a pedestrian fixture at a lower height on the back of the
pole.
Guideline 4.6.2 Pedestrian Lighting
Between roadway poles in the sidewalk, provide a pedestrian pole from the same
roadway pole family with a matching fixture to augment lighting for pedestrians. Poles
and fixtures are to be powder coated (RAL color to be determined). In the case of
Golden Gate Drive, do not replace the recently installed streetlights.

Guideline 4.6.3 Banner Arms and Pole Attachments
Banners that highlight community interests can be designed to fasten to existing street
poles. Install banner arms on all roadway poles with integrated mounts for break -away
arms to allow for banners to be hung celebrating the City of Dublin, Downtown, and any
seasonal events that are taking place. Additionally, decorative LED lights mounted on
street poles can be added that project RGB color -changing lighting on paving surfaces
and can be controlled and dimmed.
Guideline 4.6.4 String Lights and Twinkle Lights
Downtown Dublin is a destination that should feel lively during the day and night. Twinkle
lights add to a street's sense of place at night, identifying it as a special evening
destination. Toencourage use of the Downtown during the evening, install twinkle lights
first on Commercial Throughway streets (Village Parkway and Amador Plaza Road), and
then on Regional Street, Golden Gate Drive and future Downtown Local streets as shown
in Figure 2. Evaluate the success of the lights on a seasonal basis, then consider
extending the use of twinkle lights on a year-round basis. Where twinkle lights are used,
provide a maintenance plan to ensure that string lights around trunks and branches do
not inhibit tree growth and are restrung when required. Standing power receptacles for
lighting are not permitted in tree wells and should be installed in adjacent J-Boxes, as
required, and in coordination with an electrical engineer and meeting code
requirements.
4.7 STREET TREES
A street's unique character is strongly tied to the tree species found on it. Design
approach and technical considerations are in Appendix 5.0 Technical Information.
4.7.1 Tree replacement
As Downtown street trees age and require replacement, or as new development
improvements trigger updates to the public realm, install the approved trees for each
specific street. Where gaps in the Downtown urban forest exist, install new trees. Trees in
the sidewalk are to be installed with the approved City tree grate.

5. PLANNING AND
COMMUNITY PROCESS
5.1 Stakeholder Outreach and Community Workshops______________ 59
Downtown Dublin Streetscape Plan
The planning process undertaken as part of the preparation of the Plan involved
outreach with the public, City Council, landowners, business owners, etc. This included:
one-on-one and small group stakeholder interviews, two community workshops, and
online surveys.
5.1 STAKEHOLDER OUTREACH AND COMMUNITY WORKSHOPS
A series of stakeholder meetings were held to gather insights into community
perspectives, objectives and actions, concerns, and measures of success on the
Plan. The sessions addressed a series of questions:
• What defines Dublin's Downtown and what are its unique strengths?
• List the top objectives for the future of Downtown Dublin Streetscape design.
• List the top concerns about the future of Downtown Dublin Streetscape design.
• Suggest strategies or actions that could help achieve these objectives.
• List measures by which you will judge the success of the Dublin Downtown
Streetscape planning process?
The first community workshop was scheduled to listen and learn from the public about
their specific needs and desires as they relate to the public streets and spaces that
make up Downtown Dublin. The meeting consisted of a presentation of the project,
scope of improvements, existing conditions, and opportunities and constraints. The
attendees then broke into small groups to discuss and comment on Street Character,
Circulation and Traffic, Public Spaces + Street Life, and Identity, Art + Wayfinding.
The second community workshop focused on identity, gateways and art, and street
plans for the Downtown streets. The community reviewed prepared alternatives for the
distribution of space for two streets to make them safer and more pedestrian -friendly.
Input was solicited after the presentation and during a break-out session where
community members approached boards closely and inquired and commented on
the material.
Stakeholders and consultants discuss the opportunities in Downtown at
the first workshop
Community members discuss circulation and traffic concerns at
the first workshop
Community members provide input on preferred streetscape elements
as well as Village Parkway and Regional Street alternatives at the
second workshop

Downtown Dublin Streetscape Plan
6.1 STREET TREES AND UNDERSTORY PLANTING
Design Approach and Technical
• Community preferences include a variety of trees that have a strong visual
impact, flower, provide seasonal change and shade, and have low allergy -
inducing potential.
• Provide each street with a unique identity.
• Use a variety of trees to reduce the risk of large-scale tree loss due to disease.
• When multiple tree species are used on a street, group tree species in a
discernible pattern that provides rhythm and structure to the street.
• Provide continuity along Dublin Boulevard, the backbone of the street
network in Dublin.
• Planting to be climate adapted.
• Planting to be low, drought and recycled water tolerant.
• Planting to be low maintenance and suitable for urban conditions.
• Tree guards are to be avoided due to maintenance concerns and delayed
removal which impacts a tree's trunk and health.
• Plant accent trees intermittently throughout Downtown in social gathering
areas and medians.
Street Tree Planting Guidelines
Size
Recommended nursery grown container sizes is 36-inch box. Trees are to have a
minimum two-inch caliper at breast height.
Tree Species by Street
Each street is to have a consistent and unique palette of street trees in the sidewalk
and, where available, in the median (see Figure 13).

Downtown Dublin Streetscape Plan
Soils
Tree openings - Tree opening dimensions in the sidewalk will vary depending on
sidewalk widths. A minimum of 32 square feet is to be provided. A minimum width of
four feet is recommended.
Soil volume - To ensure greatest potential for large canopy trees, soil volumes are to
provide 20 cubic yards of amended soil beyond the root ball. A minimum of 12 cubic
yards is recommended, with a soil depth of 42 inches. Soil volumes will vary due to
constraints such as existing utility trenches, and infrastructure offset requirements, and
foundations. Where possible, soil trenches between trees should connect to one
another, effectively expanding the amount of soil available to adjacent trees.
Soil Cells - Soil Cells, ex. Silva Cells, are a suspended pavement system and are
recommended for use behind the curb in order to provide trees with an expanded soil
volume. This results in larger trees which are able to better shade streets and intercept
rain before it runs off into stormwater systems. Where permeable paving systems are
proposed, tree roots in soil cells create a porous soil that assists with treating and
infiltrating stormwater. It is possible to integrate the cells with both existing and
proposed utilities.
Mulch - Tree wells are to be covered with a three-inch layer of aged compost to assist
in retaining water and to prevent temperatures from rising, helping to reduce irrigation
demand.
Tree grates - Tree grates are required. See Section 5.4 Street Furnishings for tree grate
information. Manufacturer is to remove inner rings from grate to provide adequate
space for tree trunk to grow freely without encountering resistance. Grates are to be
ordered with holes provided for tree stakes to avoid having to install stake in grate
opening over the tree root ball. Request lids to cover holes when tree stakes are
removed.
Tree stakes - Use non -treated wooden three -stake arrangement and tree ties are
to be provided.
Root barriers - Root barriers are required when tree is within five feet of pavement.

Irrigation
All street trees should receive two bubblers at the rootball. If soil volume extends beyond the tree well, for example through the use of soil
cells, drip irrigation is to also be provided. In preparing planting and irrigation designs, anticipate the use of recycled water, even if not
immediately available at the time of installation.
Location
Trees are to be planted at the back of curb in the furnishing zone to allow for a clear pedestrian path of travel in the sidewalk
throughway and to help buffer traffic and pedestrians. Space trees every 10-30 feet for mature growth (see pages 67-71 for spacing by
species) with the intent of providing a continuous canopy. Allow for flexibility to accommodate a greater number of trees planted if a
typical spacing is not achievable. Early on in the design process, discuss and agree with City Staff on the canopy goals and desired tree
spacing.
Tree locations are to take into consideration City guidelines and required offsets from sightlines, street lights, and utilities and furnishings.
Adjacent to parking spaces, locate tree wells a minimum of 18 inches from the face of curb to allow for passengers to enter and exit
vehicles easily. Avoid locating trees in front of ADA parking spaces and in bus drop-off and pick-up zones where ADA ramp deployment
space is necessary. Typical offsets include:
• Traffic and stop -controlled intersection (near side) - 20 feet
• Traffic and stop -controlled intersection (far side) - 5 feet
• Driveways - 5 feet
• Utilities - 5 feet from the utility lateral center line
• Vaults - 5 feet or vault door openings, whichever is greater
Street lights - 10 feet
Street furnishings - 3 feet
In medians, propose large trees in the non -turn pocket areas. Where turn pockets narrow the median, use columnar and upright trees
which are better suited to smaller constrained spaces.
Understory Plantings
Understory plantings soften the appearance of a downtown where hardscape is often the dominant surfacing. In addition to their
beauty, understory plantings provide multiple benefits - reducing stormwater runoff, providing habitat, and helping to calm traffic.
In the Downtown district, limit understory planting to medians, bulb -outs, and stormwater treatment areas, in an effort to maximize space
for pedestrians on sidewalks that in their existing conditions are narrow in width. At -grade planting in planter strips or tree wells within the
furnishing zone may be acceptable pending approval and an approved maintenance plan by the City prior to installation. All planting
beds must take into consideration any step -out zone required for parked cars.
Downtown Dublin Streetscape Plan
Selection and Location
Use drought tolerant, native, and climate -appropriate species. Select plants that will
attain a natural form without pruning and shearing to achieve a desired shape. For
safety and visibility, use species that do not surpass 36 inches in height. Irrigate all
understory planting and ensure species are tolerant of recycled water.
The low and medium -size shrubs, perennials and stormwater plants provide a common
palette and should be selected to fit the area to be planted. Low shrubs and perennials
are appropriate in all locations and are ideal at corners, intersections, mid -block
crossings, where pedestrian visibility is critical, and sightlines are to be maintained.
Larger plants are more appropriate for medians and sidewalk planting areas where
widths are greater and in scale with their size.
Raised Plants and Potted Plants
Raised planters and potted plants are permitted if irrigated and if they do not block the
pedestrian throughway in the sidewalk. Where vaults are located in planting beds,
provide sufficient space to accommodate vault doors when open.
Hanging Baskets
Hanging baskets, if used continuously along an entire street, can reinforce a sense of
arrival and destination. Downtown Dublin should evaluate the use of hanging baskets
on slower commercial streets such as Village Parkway, Amador Plaza Road, and
Regional Street. Implement hanging baskets only if a robust maintenance plan is in
place given the amount of attention required on a seasonal basis to replace plants and
maintain their visual appeal.
At -Grade Planter Design
Each planter design should be bold in approach, relying on broad swaths and drifts of
similar plant species. Where multiple species are proposed in the same median or
planter, design using species of a similar color palette to maintain consistency. Avoid
deciduous understory plants and plants that require shearing.
Provide a 20-inch maintenance strip of permeable pavers around planting beds in
medians.
Design stormwater planting palettes to minimize species complexity to avoid small messy
areas. Species included in bioretention areas should be adapted for dry conditions with
some intermittent ponding and are to be tolerant of recycled water.
Propose aged compost as mulch which retains moisture, adds nutrients to the soil, and
does not heat up.

down to the subgrade drain
6.2 GREEN INFRASTRUCTURE
Green infrastructure refers to a set of landscape and engineering techniques used to
reduce stormwater runoff and the square footage of non -porous material while cleansing
stormwater locally and alleviating flooding in downstream stormwater infrastructure.
Examples of streetscape green infrastructure include stormwater planters, and porous
pavement. Stormwater runoff is slowed as it flows through these specially designed
systems, removing pollutants such as sediment, trash, and motor oil, before stormwater
runoff is discharged to the storm drain system, local creeks, and ultimately San Francisco
Bay. Pollutants in the stormwater runoff are removed by the soil and plants in green
infrastructure systems.
In addition to ecological benefits, green infrastructure enhances the pedestrian
experience and the visual appearance of a street, providing greenery, shade, color,
and change of season through flowers and leaves. These characteristics enhance the
sense of place and help reinforce a Downtown's identity.
At the start of each streetscape project design, a Geotechnical Report that details soil
conditions and the soil's ability to accept and infiltrate runoff will be required, as well
as consideration for which of the Best Management Practices (BMPs) below are
appropriate for the project site. Refer to the City's Green Infrastructure guidelines for
the most current requirements.
Development within Downtown will be required to follow the City's standards for Green
Infrastructure as they apply to a project's site.
74
Downtown Dublin Streetscape Plan
Components of a green infrastructure system may include:
• Flow Through Planters
Flow through planters are a vegetated approach to treating stormwater,
typically in contained concrete "boxes" located behind the curb in bulb
outs, furnishing zones, or medians. Stormwater runoff flows through an
opening in the curb face, where it collects in the planter, is treated, and
infiltrates either into the soil, or is detained for a slow release through an
underdrain. Flow through planters allow for pollutants and debris to settle out
of the stormwater before infiltration or release. If there is parking, ensure that
a step -out zone separates the planter from the curb face.
Permeable Pavers
Permeable interlocking concrete pavers can be used for stormwater
treatment. Stormwater hits the pavement, passing through the paver joints
rather than running off untreated into gutters and the storm drain system.
Water percolates through a rock base which acts as a reservoir and stores
water in the porous space between rocks as the water infiltrates into and is
cleaned by a soil subbase. The pavers can also be used for stormwater
detention. If the soil is not suitable for infiltration, a drainage system can be
installed to collect water that does not infiltrate and carry it back to a storm
drain system. In this case, the permeable paver system acts as a reservoir
slowing the movement of water downstream and not overloading the
storm drain system. Compared with stormwater planters, permeable
pavers can potentially reduce maintenance costs if planting and soils
require more frequent maintenance and replacement. Permeable pavers
can be used in the accent band of the sidewalk following the Golden
Gate Drive pattern, parking aisles, and roadways and intersections
depending upon speeds and use. Aesthetically, the color and texture of
permeable pavers provides an enhancement over standard concrete or
asphalt.
Green Infrastructure Maintenance
When deciding which green infrastructure solution to implement, evaluation of the
short and long-term maintenance requirements is needed to ensure that these factors
and life costs are incorporated into a project's budget.

Example of utility boxes grouped together to reduce visual clutter in
the sidewalk
Example of an above ground utility box integrated into the streetscape
6.3 UTILITIES
Locate utility lids and vaults in clustered groups to reduce their footprint within the
sidewalk and to limit their impact on the placement of trees and street amenities.
Position these clustered groups where trees are not allowed such as near street corners
and adjacent to streetlight poles. Align proposed utilities perpendicular to the curb and
at the back of the curb. If possible, relocate existing utility lids and vaults to the back of
curb.
This will open up opportunities for trees and planting, creating a greener and more
sustainable street. When required or advantageous, relocate existing utilities to facilitate
an improved streetscape design that maximizes space for trees and improves the
pedestrian experience. Project owners are responsible for the costs associated with
relocating existing utilities, as required by their project.

Definition: Streetscape
All landscape and hardscape improvements constructed in the
public right-of-way (excluding Downtown Dublin) that provide a
backdrop for pedestrians on the sidewalk as well as vehicles on the
street. Landscape improvements include planting in the street
median, parkway strips between the sidewalk and street, and
planting behind the sidewalk to the property line. Hardscape
improvements include entry monuments, pedestrian crosswalks,
sidewalks, and street furniture such as trash receptacles, tree
grates, bollards, benches, and light fixtures.
Background
The City of Dublin, incorporated in 1982, inherited a street system
and street landscaping plan from Alameda County that was
aesthetically inconsistent. In the past ten years in particular, the
City has spent a vast amount of time and community resources to
upgrade the existing street plantings, design new medians and
pedestrian walkways, place new public art pieces in key locations,
install new bus shelters, trash receptacles, street furniture, and
improve the overall look of Dublin's streets.
In addition to recent improvements, there are several additional
streetscape features that will be installed over the next several years.
New public art pieces will be installed in the City and the Village
Parkway corridor will benefit from new pedestrian level lighting,
widened sidewalks, and decorative paving.
As the City has grown, private development has also brought life to
Dublin's streets. New residential and commercial neighborhoods
that have been built are a testament to how attractive landscaping

Constraints
adds to a community. In new developments throughout Dublin,
there was an opportunity to design the streetscape as an integral
element to the project. The result provides a basis for a healthy,
mature, attractive streetscape for many years to come.
As Dublin has evolved, it has become clear that although
streetscape design within neighborhoods or commercial districts
can vary from one to another, it is important for the streets that tie
those districts together have a common streetscape palette to
provide consistency between areas. For,instance, although
benches along the Village Parkway corrir•lor will likely he a different
chyle from the benches installed in the Historic District the benches
f
along the City's mein streets that tie the districts together should he
consistent from one end to the next
Goals of the Streetscape Master Plan
Although Dublin has had many successes in creating attractive
streetscape designs, the City has not adopted a formalized plan to
guide the continuation of good streetscape design in the public right
of way.
The goals and intent of the Streetscape Master Plan are to:
1 Recognize and formalize the City's existing landscape and
tree planting program;
2 Strengthen, clarify, and unify the City's streetscape
furnishings palette;
3 Provide opportunities for creating attractive entries into the
City;

Monument signage
Existing conditions
Existing monument sign installed at Village Parkway near
northern border, at Dougherty Road near Dublin Blvd., and San
Ramon Road near Dublin Blvd.
City of Dublin Streetscape Master Plan
Recommendation
Install the proposed City of Dublin Monument sign in the median at key
gateways to the City:
Con Ramon Doom of Dublin Boulevard
Dougherty Road at Dublin Boulevard
Hacienda Drive at Dublin Boulevard
Tassajara Road at Dublin Boulevard
Fallon Road at Dublin Boulevard
San Ramon Road at the northern entry to City
Village Parkway at the northern entry to City
Dougherty Road at the northern entry to City
Tassajara Road at the northern entry to the City
Dublin Boulevard at Schaefer Ranch and in EDPO
Over time, the existing monument signage can be removed and replaced
with the proposed design, which still needs to be detailed and fabricated.
The design shown below left, which was reviewed by the City Council in
November, 1999, is conceptual only and will need to be refined and
fabricated before it is installed.
Proposed design
Proposed granite City of Dublin
monument sign. Simple, yet
more refined and updated from
the existing signs. Similar in
-
design and materials to the
identification sign at Emerald
Glen Park.

Section 2: Existing Street Tree planting locations and recommended changes
The following table notes the planting palette for each of the City's major streets and makes recommendations on whether the planting palette
should continue as is or be changed in any way. The goal of the recommended changes is to ensure that a healthy street tree canopy matures
over time and that the theme of growing a strong, fall color, and statuesque large canopy tree on the City's main east -west arterial (Dublin
Boulevard) and a delicate, flowering tree full of spring color on the main north -south streets is continued.

Continue planting of London Plane trees at an ideal spacing

plantings and plan to retrofit existing 4'x4' grates. Median
planting is ideally a combination of London Plane trees to
provide a canopy and a smaller, flowering tree to provide
color and visual interest.

Planting Notes:
1. Bradford Pear has been widely used throughout the City and in the west in particular. The tree has done well in most places but should not continue to be used. The species is pror
to fireblight that could potentially eliminate the entire population. The Bradford Pear should be replaced with Yoshino Flowering Cherry as new installations occur. The two a
similar in form and flower, so the north -south flowering tree theme can be maintained.
2. Sweetgum has been installed in narrow sidewalk planters in some locations. This is a water -loving tree and should not be planted in constricted areas. Use in tree wells should t
discontinued and should be used in medians only.
3. Dougherty Road is an opportunity to create a striking new planting scheme when it is widened per planned improvements. The existing row of London Plane trees on the eastern sic
of the road merits the use of a picturesque, delicate, flowering tree in the future median to establish the design of the street and continue the north -south flowering tree theme.
4. Chinese hackberry are experiencing some health issues in Dublin Ranch. An arborist should be consulted.
5. Camphor trees on Gleason Drive look stunted and weakly. This could be because of poorly drained soils. The tree should be replaced and not be used as a street tree in the future.
6. The strawberry tree can be messy and should continue to be used in medians only.

Policy Section 2: Gateway Treatments
The following intersections are considered key gateway entrances
into the City of Dublin. Enhanced landscaping, "City of Dublin"
monument signage, widened medians and special median
treatment, possible placement of public art, and the careful
orientation of buildings to the intersection shall all be considered to
draw attention to these gateway areas:
. Dougherty Road at Dublin Boulevard
r' Hacienda Drive at Dublin Boulevard
Tassajara Road at Dublin Boulevard
Fallon Road at Dublin Boulevard
San Ramon Road at the northern city limits
Village Parkway at the northern city limits
Dougherty Road at the northern city limits
:} Tassajara Road at the northern city limits
Dublin Boulevard at the western city limits (Schaefer Ranch)
Dublin Boulevard at the eastern city limits (East Dublin
Property Owners/Fallon Village)
Implementation Suggestion -
Street medians at future gateway intersections should be of
sufficient width (a minimum of 10 feet unless otherwise approved) to
allow for enhanced landscape and entry monumentation.
City of Dublin Streetscape Master Plan
Policy Section 3:
and Maintenance
7.1.d
Streetscape Furnishing, Planting Standards,
It is the goal of the following policies to coordinate the design and
installation of streetscape improvements with other uses along the
public right-of-way and to maintain Dublin's streetscape planting so
that it grows and develops over time into a healthy, mature
landscape that is an amenity to the City and its residents.
Implementation Suggestions:
1. Street trees shall be planted in the public service easement,
public right-of-way, or in a parkway strip, and not on private
property, if at all possible, and shall be maintained by a
homeowners association or by the City of Dublin as
appropriate.
Page 33
2. If a required street tree is planted on private property, the
property owner shall be responsible for the ongoing
maintenance of the street tree. Should the tree be removed
from its location, a replacement tree of the same type and
size shall be planted elsewhere in the front yard area of the
private property. In addition, the requirement to maintain
the street tree shall be included in the Covenants, Codes,
and Restrictions (CC&Rs) for the development and shall be
included as a deed restriction on the homeowner's property.
3. As new commercial and residential neighborhoods are
constructed in Dublin, it shall be the responsibility of the
developer to install street tree plantings and street
furnishings in the adjacent public right of way as specified by
this document. If the project has frontage onto Dublin
Boulevard, the developer shall also be responsible for
installing the proposed Dublin Boulevard Identity Markers in
suitable median locations. If the project is adjacent to a City
gateway, the developer shall be responsible for installing a
City monument sign.
