Reconnecting Communities and Neighborhoods Grant Program
Project Name: Connecting Miami: I-395 Underdeck and Heritage Trail
Applicant: City of Miami
Award Amount: $60,353,730.00
Program: Neighborhood Access and Equity
Estimated Total Project Costs: $82,653,730.00
Project Description: Connecting Miami: I-395 Underdeck and Heritage Trail (the Underdeck), is a planned public
landscape that weaves below the elevated 1-395 highway viaducts, creating a 33-acre urban open space and
streetscapes that will reunite the urban fabric of Overtown, a historically Black neighborhood that was disconnected
during highway construction in the 1960s. A mile -long "Heritage Trail" will connect neighborhoods across active rail
tracks, linking Overtown to Biscayne Bay. The Underdeck will provide a safe place for walking, jogging, biking, and
scooting, encouraging non -vehicular transportation options, while improving quality of life, economic vitality, and
social equity for all through the creation of an environmentally sustainable and resilient urban landscape.
Congratulations! The U.S. Department of Transportation (USDOT) selects the above project to receive a Fiscal Year
2023 Reconnecting Communities and Neighborhoods (RCN) Program grant.
Importantly, projects receiving RCN grant funding cannot be used for additional through travel lanes for single -
occupant passenger vehicles or highway expansion.
The USDOT Operating Administration overseeing your project will be contacting you soon with next steps, including
execution of a grant agreement. You will also receive a follow up invitation to attend a webinar to welcome you to

Re: Neighborhood Access & Equity (NAE) Capital Grant
Dear Mr. Ortiz,
On behalf of the City of Miami Mayor, Commissioners, and community, thank you for the Reconnecting
Communities & Neighborhoods grant for the Underdeck. We have decided to transfer the grant to the Florida
Department of Transportation, District Six (FDOT), as recipient and administering agency.
The reasons for this decision include FDOT's increased resources and experience in administering federal
grants of this size. We believe such resources and experience will greatly benefit the project process and
timeline. However, as DOT and FDOT negotiate and draft the grant agreement, we ask for language
memorializing the City's continuing involvement with public engagement and design.
Sincerely,
DocuSigned by:

A. OVERVIEW
The Connecting Miami: 1-395 Underdeck and Heritage Trail grant application requests Capital
Construction Grant funding under the Neighborhood Access and Equity (NAE) program.
PROJECT SCOPE
The original construction of I-395 and 1-95 in Miami severed established neighborhoods and
communities from each other. The Connecting Miami: 1-395 Underdeck and Heritage Trail
Project ("Underdeck") will transform the barrier of the original highway by integrating a 33-acre
public open space and mile -long trail system below I-395. By uniting neighborhoods impacted and
divided by the decades -old highway project, the Underdeck will transform I-395 from a feature
that divides into one that reconnects and revitalizes communities (Figure 1).
The Florida Department of Transportation (FDOT) is currently reconstructing the I-395 viaducts,
including the construction of an iconic "fountain" bridge structure that will change Miami's
skyline. The Underdeck will create a safe, welcoming, and vibrant open space and multimodal
connectivity at street level, reconnecting residents and businesses in Overtown north and south
of the highway, and building new connections east and west between Gibson Park and Biscayne
Bay. The Underdeck revitalization will connect communities to new employment, civic, and
recreational opportunities (see Fact Sheet in Appendix A).

In order to create the opportunity for the Underdeck, I-395 bridge decks are being raised from
current 18-foot clearances up to 63 feet, with fewer columns (reduced from 800 to 94). The
Underdeck will be an urban oasis flooded with daylight but shielded from tropical sun and showers
(Figure 2). The Heritage Trail will be an iconic 1-mile active transportation spine, a wide
meandering walkway through the open space under I-395, with a signature shared -use bridge
over the Florida East Coast Railroad (FEC Railroad). Conceived with robust community input,
the Underdeck will provide diverse multimodal connections to bus and rail, bicycle/pedestrian
corridors and rideshare; prioritize accessibility for persons of all ages and abilities; integrated
expansive urban tree plantings and resilient landscaping; and a broad range of public amenities to
support active and passive recreation, gatherings and events, and daily civic life for local residents
and visitors. Appendix B provides Underdeck schematics.

BARRIERS AND BURDENS POSED BYTHE HIGHWAYS
Highway construction in the late 1960s caused large-
scale and lasting harm to Overtown, displacing hundreds
of dwellings and residents and dozens of businesses. It
additionally introduced physical barriers into the urban
fabric, limiting access to equitable urban mobility
and economic development (Figure 3). The "under the
highway" wasteland has divided and isolated Overtown
and had negative impacts on property value, housing
conditions, public safety, and business activity. More is
provided in Merit Criterion #3 Facility Suitability.
During development of the I-395 reconstruction project,
which included extensive public and agency coordination,
the opportunity to transform the area under the I-395
viaducts into a signature public open space — a landscape of
connection — took root.

Overtown neighborhood fabric
HISTORY AND CHARACTER OF AFFECTED COMMUNITIES
Founded in the 1890s, "Overtown" is one of the oldest neighborhoods in Miami, settled by
Bahamians, who were not accepted elsewhere in the City. This African American community was
situated across the FEC railroad tracks from predominantly white communities, closer to the citrus
and pineapple farms to the west. The name "Overtown" came from people saying that they were
going "over town" to this neighborhood. The area grew and developed into a vibrant community
until the early 1960's, when the construction of the expressways cut through and significantly
degraded the neighborhood. Tragically, this construction forced many residents to relocate (see
Appendix C), and it contributed to the persistent economic and physical decline of Overtown.
The City of Miami has emerged as an international trade center and a culturally vibrant destination.
However, it remains a "tale of two cities" with 21% residents living in poverty. Neighborhoods
such as Overtown are marked by lagging wage growth, surging housing costs, and a shortage
of affordable housing. Overtown's economic and health profile is depressed below average
conditions. Its residents are extremely low income, negatively impacted by urban environmental
disparities, and experience higher incidence of acute illnesses.
Connecting Miami: I-395 Underdeck and Heritage Trail 2
B. LOCATION AND MAP
The Underdeck is located under the I-395 viaduct in Downtown Miami. It is part of the "Connecting
Miami I-395/SR-836/I-95" Design -Build highway reconstruction project, which is currently
underway. The three freeways are major regional transportation conduits, converging downtown at
the Midtown Interchange crossroads, serving commuters and commerce, and connecting to freight
and passenger hubs at PortMiami to the east and Miami International Airport to the west. The busy
Florida East Coast (FEC) Railroad passes under I-395 and crosses the Underdeck corridor.
Figure 4 shows the Underdeck
site, unifying the historic
Overtown community west of the
FEC Railroad, and connecting
across the active tracks to the
Arts & Entertainment District
to the east, which includes the
Arsht Center for the Performing
Arts, the Perez Art Museum, and
the Frost Science Museum on
Biscayne Bay. Census Tracts 31
and 34 west of the FEC Railroad
are both Areas of Persistent
Poverty and Historically
Disadvantaged Communities.
These burdened communities
will benefit substantially from the Underdeck.
FIGURE 4 Underdeck Project Area under 1-395 viaduct
C. MERIT CRITERIA
1. Equity and Environmental Justice
Historic burdens and disparities, and equity in benefits
The highway construction caused large-scale and lasting harm to Overtown in the form of
barriers to mobility, economic development, and access. The highway displaced hundreds of
dwellings and residents, and destroyed dozens of businesses. The landscape under the I-395
viaducts is dark, noisy, barren, unused, and uninviting, which has long inhibited revitalization of
Overtown's neighborhood fabric. Indicators of on -going community burdens and underinvestment
include high unemployment rates, low job growth, low household income, low auto ownership,
high traffic safety vulnerability, high health and heat vulnerability, and low property values (see
Appendix C).
Using the Climate and Economic Justice
Screening Tool (CEJST), Table 1 shows
that within 1/2-mile of the Underdeck most
census tracts are significantly burdened
and underserved.
• Overtown's median income is
$28,010 vs. Miami's $47,860 and
Florida's $61,777. Over 75% of
households have incomes less than
twice the poverty level, or about
$50,000 (Figure 5).

• Most residents are renters (87%) and
rent -burdened (56%).
• Justice40 communities, Federal
Opportunity and Empowerment
Zones are located within 1-mile of
the Underdeck. These historically
disadvantaged and vulnerable
neighborhoods will benefit significantly
from the project.
• Most of the Census Tracts for the project
exhibit high poverty levels and an Social
Vulnerability Index (SVI) ranking over
0.99 (Figure 6).
• 40-60% of these households do not
have cars, indicating an urgent need for
alternative multimodal transportation
options.
Construction -related community displacement
The Underdeck project does not require
any new right-of-way as it will be built on
FDOT property underneath the elevated
I-395 roadways. To preserve community
character and prevent displacement of
existing residents and businesses, the City
is proactively utilizing its Miami 21 land
use policy and zoning, the Fair Housing and
Affordable Housing programs, and local
Community Redevelopment Areas' (CRA)
housing attainability programs.

The Connecting Miami highway project including the Underdeck has secured the necessary
environmental clearances (see Appendix D), and has no significant adverse impacts. Commitments
were made by FDOT to manage the construction process to minimize impacts such as noise, dust,
and other construction disruptions. The Underdeck construction will occur concurrently under the
elevated highway footprint, with no additional impacts.
Project equity in impacts and benefits
The Underdeck will create more equitable opportunities for recreation, access to nature / open
space, and expanded multimodal transportation options, for historically disadvantaged and
burdened communities adjacent to the project area.
Recreation & Programming: A community -led planning process identified diverse programming
for the Underdeck, including an amphitheater, play areas, interactive water features, event plaza,
and sports courts — expanding access to opportunities for health and wellness for local communities
that currently lack access to these urban amenities.
Access to Nature / Open Space: The project includes over 15 acres of native and adapted plantings
and 1,315 new trees, creating a green oasis and respite in the urban center.
Multimodal Transportation Options: Travel analysis shows that 25% of Underdeck walking
Connecting Miami: I-395 Underdeck and Heritage Trail 4
and bicycling trips are associated with Overtown. The project's central E-W Heritage Trail and
revitalized N-S streetscapes will create convenient options for connection to jobs or personal trips.
Economic Opportunities: The Underdeck will generate a positive economic impact on the
community, serving as an active destination; stimulating growth of nearby retail and businesses
catering to local and out-of-town visitors; and creating synergy with other downtown destinations
including the cultural and arts destinations on the project's eastern end.
2. Access
Affordable transportation for safe mobility and connectivity
The Underdeck will provide a safe, multi-
use transportation network to support
daily neighborhood connectivity and
access to destinations like affordable
housing, jobs, healthcare, grocery stores,
schools, places of worship, recreation, and
parks. The Underdeck is part of a broader
evolution towards a more walkable and
transit -oriented urban experience. In
addition to reinforcing street -level linkages
for pedestrians and bicyclists through
interconnectivity (Figure 7) with Miami's
greenways, bicycle routes, and transit
services, the Underdeck also features six
micro -mobility hubs for rideshare and
scooters — anticipating that it will be an
iconic destination that is the first mile/last
mile linkage for many trips.
Safe accommodation for all users
The Underdeck will support the broader
urban district to achieve its full potential
as a diverse, walkable neighborhood.
The Underdeck will become a new
"Main Street" and community center.
Connectivity and recreation for local
residents and visitors are encouraged
through a richly planted landscape below
the highway, protected from Miami's
intense sun and rain, supporting new
access to nature and recreation that will
enhance community health and wellness.
The project has been incorporated as a
significant feature into the City's 2023
Parks and Recreation Master Plan, Bike
and Climate Action Plan.

Master Plan, Comprehensive Neighborhood Plan
Encourage thriving communities with transportation choices
The Underdeck is poised to become a major active transportation hub for work and social/
recreational trips. Data from the regional travel demand model within 1/2-mile of the Underdeck
shows that for trips made within this area:
Connecting Miami: I-395 Underdeck and Heritage Trail 5
• Residents of the Underdeck influence zone walk, bike, and use public transit:
• Non -auto trips dominate at 64% of all trips (vs. regional average of 85%).
• Active transportation trips account for 54% of trips.
• Bicycle and transit trips are above the City and regional averages at 10% each.
• Walking trips at 44% exceed driving trips at 36%.
• Residents of the Underdeck influence zone have already chosen to live close to work.
• Work purpose trips are 50.4% (vs. 35% regionally).
• Of 70,343 jobs in the two corridor zip codes, 52.5% were held by resident workers vs.
47.5% net commuter -based workers. miami-fl.eimpactv3.com/dashboards/171/miami/
Commuting -Patterns).
National Roadway Safety Strategy (NRSS)
The Underdeck and Heritage Trail project closely aligns with the public safety objectives of the
NRSS's "Safer People" policy. The Miami -Dade County 2021 Vision Zero Framework Plan
(miamidade.gov/transit/library/vision-zero-framework-plan.pdf) identified the Overtown area
west of the FEC Railroad and all of downtown Miami as areas with high crash rates involving
pedestrians and bicyclists. The Miami region is cited in the most recent 2022 Dangerous by
Design report (https://smartgrowthamerica.org/dangerous-by-design/) as the 14th most dangerous
(fatality rate) metro area. Overtown's transportation disadvantaged residents (as pedestrians and
bicyclists) have a high rate of crash involvement due to reliance on non -automotive travel for daily
mobility.
The Underdeck enhances the safety of Overtown's active travelers by providing a safe shared -
use trail east -west, which is separated from vehicular traffic and includes signalized street
crossings. The Underdeck also integrates and enhances adjacent streetscapes in all directions,
incorporating FDOT policy guidance for Complete Streets, a context -sensitive approach to ensure
safe, multimodal urban connectivity. The City has integrated the Underdeck into its citywide
bicycle/greenway network planning and Pedestrian Priority Zone (PPZ), which supports the
creation of a safe environment for pedestrians, including pedestrian -oriented street design and
traffic calming elements.
3. Facility Suitability
Barriers impeding access, mobility, and economic development
The original highway construction divided neighborhoods and introduced physical barriers into
the urban fabric, creating impediments to community mobility, economic development, and
equitable access to recreation. The landscape under the I-395 viaducts is currently dark, noisy,
barren, unused, and uninviting — an unsafe and divisive transportation facility. The Underdeck
proposes to create a safe and inviting corridor reconnecting residents and businesses in Overtown
across the highway, and linking them to employment, civic, and recreational opportunities across
the City. The mile -long Underdeck will transform this long-standing barrier into a signature 33-
acre open space with a vibrant, cohesive, world -class active transportation corridor and destination,
revitalizing economic opportunities and quality of life in Overtown for residents to safely live,
work and play.
Environmental burdens on the community
Urban Forest Deficit & Urban Heat Island: Tree canopy in the census tracts surrounding the
Underdeck is well below Miami's citywide 23% tree coverage (Table 2). The concrete decking of
I-395 serves as a heat sink from the tropical sun, aggravating the "urban heat island effect". The
Connecting Miami: I-395 Underdeck and Heritage Trail 6
highway right-of-way is essentially treeless
and devoid of landscaping, contributing to
increased surface temperatures and heat
capture in this project area. Extreme heat is
responsible for more than 30 deaths/yr. in

Park & Open Space Deficit: Seven City parks are located within 1/2-mile of the Underdeck, serving
a population of 25,248 and providing good access within a 10-minute walk. However, these parks
comprise only 48.5 acres, which offers 1.92 acres/1,000 persons, well below national standards of
peer cities that target at least 4 acres/1,000 persons. This ratio declines to 0.75 acres/1,000 persons
in 2045, with the projected population in this area increasing to 64,418 persons. The Underdeck's
33 acres would increase area green/park space by 70% and swell the existing ratio from 1.92
to 3.23 acres/person. With over 15 acres of urban gardens and 1,315 new trees, the Underdeck
provides a restorative nature -based facility for recreation and respite in a rapidly growing setting,
enhancing the community's quality of life and environmental resilience.
Addressing vulnerabilities that are clear threats
The primary challenge confronting the community is how to leverage the on -going I-395
reconstruction to mitigate the highway's long-standing barrier effect through the creation of
a destination open space and multimodal corridor that reconnects the neighborhood fabric of
Overtown, and links Overtown to the broader City (Figure 9). The risk for the community is that
the benefits of the reconstructed highway will be felt "above the city" by drivers — but not by the
community that lives at the base of this significant transportation infrastructure.
FIGURE 9 1-395 Underdeck Before and After
Expansive Public Open Space: The Underdeck concept "flips the script" on the common
problem of an urban freeway dividing the urban fabric. Instead of burying and capping over the
highway, which hydrologic conditions in Miami would not allow, the Underdeck will transform
the harsh conditions under the freeway to reconnect neighborhoods long divided and create a
much needed public urban open space for local residents. The Underdeck does this at the cost
of $2.4 million/acre, which allows for a much more expansive open space area, compared to
a typical freeway lid project ($48 million/acre or 20 times the unit cost of the Underdeck).
Urban Infrastructure for Rapidly Growing Area: The rapid transformation of the Miami urban
core is taking the form of new high rises, including in Overtown. Much of this new development
includes workforce housing with ground floor retail space. Table 3 shows forecasted growth with
Connecting Miami: I-395 Underdeck and Heritage Trail 7
dramatic increases of 131% in population
and 47% in employment. Greater Miami
attracts 26.5M visitors/year (40% visit
downtown). With housing, population,
employment, and tourism increasing, the
Underdeck provides necessary urban
infrastructure and open space amenities
to support equitable access to nature,
recreation, and integrated mobility
options.

The Connecting Miami project will reconstruct surface streets next to the Underdeck with treed
sidewalks and bicycle lanes; it will also upgrade affected traffic signals with enhanced pedestrian
crosswalks. Just above, I-395 will continue to serve as a critical freight link for truck traffic through
the tunnel to PortMiami, which is the loth busiest container port in the US and 1st in Florida.
4. Community Engagement and Partnerships
Community Participation
The project has involved an extensive community and stakeholder outreach and engagement
process. FDOT initiated corridor planning outreach in 2004, which has continued through its
current highway construction. This process has engaged with a wide range of public entities,
including the Miami -Dade Transportation Planning Organization (TPO), Miami -Dade County,
local stakeholders, freight and logistics interests, and elected officials.
The project has also prioritized inclusion of local communities and civic organizations in an
engaged and participatory planning and design process (Figure
10). This process has directly confronted the historic environmental
justice issues associated with the original land takings in Overtown.
It has also progressed in coordination with associated and interrelated
planning initiatives of the City of Miami, South -East Overtown-
Park West (SEOPW) Community Redevelopment Agency (CRA),
and civic foundations for Overtown's renewal. The Omni CRA and
SEOPW CRA boundaries surround the Underdeck corridor and are
key community advocates and redevelopment partners.
The FDOT Community Outreach Office logged over 100 outreach
efforts, in addition to helping neighbors review on-line employment
opportunities and job placement. This office employed a variety
of methods to connect with the community, with thorough
documentation of contacts. By the time the highway project was
advanced to its Public Hearing, some 15 community representative
organizations provided letters of support, reflecting the impact of "1
the project's comprehensive community process.
The City of Miami is LEADING the project's next steps through
the design, construction, and post -design phases of delivering
on the promise of a vibrant urban landscape that reconnects
communities. The City is building on the years of community FIGURE
collaboration AND continuing coordination with the CRAs,
Overtown business and community interests, the Downtown Development Authority (DDA), other
cooperating developers and stakeholders, and with all adjacent communities.

Community Centered Approach
The Underdeck concept is the result of a community -centered approach to envision a reconnected
neighborhood that meaningfully redresses historic inequities and benefits economically
disadvantaged communities. It advances the evolution of Miami's urban character as a
compact and walkable city, with reduced reliance on vehicles, and a more livable and sustainable
environment. It complements the vertical development along the corridor, providing essential open
space and equitable access to recreation. For the isolated Overtown community to the west, it
serves as a bidirectional gateway to the Historic Overtown Business District north and south,
and to the employment, shopping, business, and cultural attractions to the east. As a destination
for residents and visitors, the Underdeck will increase visitation of the public space AND local
establishments in neighboring communities. The climate -ready open space can support food, music,
and art festivals, farmer's markets, performances, and vendor carts that will further stimulate the
local urban economy. Community input has been woven into the form, function, and features
to foster equitable development while connecting people and communities.
Ongoing Community Partnerships
The completion of the project and its ongoing operation will continue to be defined by several key
community partnerships summarized as follows (see partnership letters in Appendix E):
1 FDOT — Memo of Understanding and Long -Term Use Agreement (Partnership/funding)
2. Southeast Overtown/Park West CRA — Letter of Commitment (Partnership/funding support)
3 Omni CRA — Letter of Commitment (Partnership/funding support)
4. Downtown Development Authority (DDA) — Letter of Support and Collaboration
FDOT allocated $12M to cover expenses related to designing and constructing the pedestrian
and bicycle overpass across the busy FEC Railroad and committed $11.5M to support design and
construction of the Underdeck and Heritage Trail.
Both CRAs have committed up to $3.5M each for the implementation of the Underdeck, which
aligns seamlessly with their respective missions. The existing community revitalization
programs of the CRAs will be used going forward to maintain interactive engagement with
the Overtown community and other neighborhoods within the CRAs.
These partnerships reinforce the community -based approach deployed in the planning and
conceptual design of the Underdeck and Heritage Trail. This collaboration will continue through
the final design phase, including development of public art and trail amenities, and onward
through construction and post -construction, including long-term operations and maintenance
(O&M), and programming of activities and events to ensure the Underdeck is a vibrant and
welcoming civic asset for all.
Addressing Community Priorities
The Consensus Plan design is the result of
considerable coordination and engagement
with the Overtown community, reflecting many
neighborhood priorities (Figure 11):
• safe crossings, provide pathways and trails for
connectivity and non -motorized transportation
• showcase the culture and history of Overtown
• provide open green space with trees, urban
gardens
FIGURE 11 Resident's vision for Underdeck near
Overtown celebrating culture and providing
connectivity
Connecting Miami: I-395 Underdeck and Heritage Trail

• playgrounds and activities for all ages and abilities
• access to public transport to/from home and work
• pedestrian bridge over the train tracks
The community also emphasized the need for the Underdeck to serve as a thriving economic
corridor providing space for vendors, food operators, business owners and local entities to
strengthen local business and create employment opportunities. Throughout the Underdeck's
development, the Underdeck Advisory Committee (UAC), comprising of community
stakeholders, had a seat at the table alongside the City, FDOT, and Town Square Neighborhood
Development Corporation (a local non-profit). UAC recommendations on a management
framework for the Underdeck public space were submitted to the City for consideration.
FIGURE 12 Underdeck elements based on community input
Per Committee recommendations, the City of Miami will continue engaging stakeholders during
the project's final design and implementation. Led by the City of Miami, the Underdeck Advisory
Committee will be restructured to align its membership with the proj ect's next steps of implementing
the Consensus Plan and maintaining the site. The Committee will include participation of City
Depailinents such as Real Estate, Parks and Recreation, Capital Improvements, Opportunity
(employment) Center, and Resilience and Sustainability. The Committee will reflect a cross-
referenced representation of stakeholders and local residents at all stages of the project. The
CRAs will also be integral to the decision -making process to ensure the community benefits and
that "legacy" residents and businesses can remain living and operating in Overtown. The
Committee is committed to proactively addressing equity and environmental justice, transportation
inequities, prior social injustices, economic opportunities, employment at or above a living wage,
historic and cultural preservation, housing challenges, climate change and sustainability, and
access to recreation, helping to strengthen the Underdeck's connection between Overtown and
nearby Miami neighborhoods.

be used for the project design, construction, and construction engineering/inspection. The City
and FDOT will enter into a Long -Term Agreement and Occupancy Agreement for the use of the
FDOT right-of-way, detailing the responsibilities of each party. The City of Miami will assume the
responsibility for the ongoing operations and maintenance (O&M) of the Underdeck and Heritage
Trail at an estimated cost of $6M/yr. The standard of care and maintenance will be balanced with
fiscal consideration, service delivery, safety, and maintenance need to ensure the capital investment
in the Underdeck is enjoyable, safe, and productive for years to come.
5. Equitable Development
Community restoration, stabilization, and anti -displacement strategies
In 2011, the City adopted its progressive Miami 21 land use code representing the "Miami of the
21st Century". Guided by tenets of New Urbanism and Smart Growth, this form -based zoning
code promotes transit -oriented, pedestrian -friendly growth and walkable urbanism, and discourages
disjointed, car -centered development. Current trends in the Underdeck vicinity, as discussed in
Merit Criterion 3 — Facility Suitability, show ongoing, market -driven development, much of
which includes a workforce housing component, extending along the corridor and westward into
Overtown. As the area population increases, developers are responding to affordable housing needs
guided by "Miami 21", which includes density bonuses in transit -oriented development districts
and for workforce housing and other features that will be important to support retention of current
residents of Overtown and the Underdeck vicinity.
In addition to the affordable housing preservation strategies included in FY2019-2023 HUD
Consolidated Plan, the City also employs a wide range of programs and activities to further fair
housing practices, advance housing preservation and neighborhood revitalization (Table 5).

The Underdeck is located within the boundaries of the SEOPW and Omni CRAs. Both
agencies were formed to revitalize neighborhoods including Overtown, aid in the development of
projects (private & public), alleviate conditions contributing blight, and create affordable/attainable
housing. One of their required actions is to restore the urban fabric and mitigate negative impacts
of previous transportation improvements. A set of strategies has already been initiated to stabilize
and reduce displacement. Additional programs to strengthen the economy and interconnectivity
for residents in the CRAs, including affordable/attainable housing, business incentives, historic
preservation and workforce development.
Connecting Miami: I-395 Underdeck and Heritage Trail 11
FIGURE 13 Underdeck Heritage Trail at night, with art features, lush landscaping, and iconic Fountain bridge
Creative place -making that celebrates local history and culture
The Underdeck concept emerged through extensive community engagement, which clarified the
need to transform the longstanding barrier of I-395 into a landscape of connection. An important
project component is the recognition and
tribute to the history of Overtown in a
meaningful way. That vision was captured
by branding the corridor as the Heritage Trail
(Figure 13), a civic promenade that celebrates
Overtown and the diverse cultural heritage of
Miami.
The "art in public places" aspect of the
project incorporates design elements and
historic markers that pay tribute to the
culture and legacy of Overtown. Beyond
that component, the project was conceived
to re -link Overtown via the Underdeck
and Heritage Trail to the communities and
opportunities to the east. The bridge over the
active FEC rail corridor is a critical element
in this connectivity. In addition, the project
is context sensitive seeking to integrate with
existing land uses in Overtown and encourage
the establishment of new businesses to the north and south of the project site (Figure 14).
Supports a Local/Regional/State Equitable Development Plan
Envisioning 2035 is Miami's Comprehensive Neighborhood Plan, a high-level policy document
that sets community vision and direction for the equitable and sustainable attention to future
community needs. It contains nine elements including: Future Land Use, Housing, Groundwater,
Transportation, Open Space, Natural Resources, and Capital Improvement.
Specific policies relating to the Underdeck are paraphrased below:

Policy TR-
2.1.6
The character of existing neighborhoods
will be respected when establishing design
guidelines for connectivity and transit
infrastructure.
The Underdeck aligns with this policy
based on its extensive community -based
input into the project concept definition.
Policy TR-
2.9.1
Support implementation of the Underline
and other `green corridors' to improve the
bicycle network for a healthier lifestyle and
use of alternative modes.
The Underdeck serves as both an active
transportation access corridor and
destination, promoting a healthier lifestyle,
and interconnecting with other modes.
Policy TR-
2.9.10
Remove physical and psychological
barriers that prevent the connection of
existing bicycle and pedestrian facilities.
The Underdeck provides a critical rail
over crossing, and transforms an "under
the highway" barrier to an urban trail/
open space reconnecting neighborhoods.
The SEOPW CRA 2018 Redevelopment Plan Update provides strategies for activities, programs,
and initiatives. The Plan goals include (1) Preservation of historic buildings and cultural heritage,
(2) Expand tax base using Public -Private Principles, (3) Provide and retain housing affordability,
(4) Create jobs within the community, (5) Promote community as cultural and entertainment
destination, (6) Improve quality of life for residents, (7) Promote entrepreneurship and technology
innovation, (8) Ensure transit connections to employment centers and (9) Foster"Save Community"
initiatives. This Plan also highlights the Underdeck as transforming the area beneath I-395 into a
vibrant open communal space for the enjoyment of Overtown residents.
Encouraging public and private investments
There is already significant ongoing
development in the project vicinity
as seen in Figure 15. Many of these
buildings include workforce housing
and first floor retail, elements that
reinforce pedestrian street -level
urban experience, as promoted by
the Miami 21 zoning code and CRA
Redevelopment Plan. These features
are incrementally contributing to a
more walkable and livable setting.
This district already enjoys a dense
network of transit services from
free City trolleys to regional transit
and intercity rail five blocks south
of the corridor. As a significant
green enhancement to the urban public realm, the Underdeck will serve as a
additional public and private investment to support equitable development.
Land use policies that reduce regional displacement pressures
FIGURE 15 Existing development context surrounding the Underdeck
catalyst to intensify
The form -based code designates land use types permitted in the various zoning districts. This
code provides protection for existing uses, and applications for re -zoning to higher densities
are scrutinized, to address community preservation priorities and encourage mixed -income
development. In addition, flexibility for ancillary units is permitted where specific zoning
designations are present.

6. Climate and Environment
The Underdeck project will have significant qualitative and quantitative positive impacts on
the local climate and environment, which will benefit local residents and visitors. Identified as
a CLIMATE JUSTICE COMMUNITY — an historically underinvested neighborhood that is
climate -vulnerable to natural hazards and socially vulnerable — Overtown will particularly benefit
from the transformation of the I-395 corridor into a sustainable and resilient public landscape.
Expected reduction of adverse environmental impacts
Expected Reduction in Transportation -Related and Air Pollution and GHG Emissions:
1. Daily travelers - 2,150 in 2023 and 4,000
in 2045 - can be expected to utilize the
Underdeck walking or bicycling.
2. The 1,315 new trees will greatly contribute
to air quality and stormwater flow per
analysis using the iTree tool from the
USDA Forest Service (see Table 6).
3. Stimulate significant additional non -

Hot Spot Areas of Extreme Heat: New tree planting will address extreme heat in Miami's
urban core benefiting underserved communities and vulnerable populations which are the most
impacted by disproportionate environmental and/or public health issues of extreme heat. The 33-
acre Underdeck will build resilience through tree shading to reduce heat island effect in an area
with elevated temperatures averaging 8°F.
Access To Greenspace: The Underdeck will increase the amount of park/open space within 1/2-
mile of the project from 48.5 to 81.5 acres, nearly a 70% increase, with a lush landscaping palette
(Figure 16). The amount of park space per person will increase from the current 1.92 acres/1,000
persons to 3.23 acres/1,000 persons.

and the choice of native plants across six distinct palettes are guided by varying sun/shade and rain
conditions under the I-395 viaducts. Pervious pathways will improve stormwater absorption.
High -quality choices for lower -carbon travel
The Underdeck's Heritage Trail will provide a continuous, one -mile long active transportation
mobility corridor with convenient first -mile -last mile connectivity. This includes micromobility
hubs for rideshare and scooters, links to adjacent greenways and bicycle routes, and connections to
free City trolleys and local, regional and intercity transit services. The Underdeck will also connect
to County and State trails further expanding eco-friendly transportation alternatives throughout the
South Florida region.
Alignment with Local/Regional/State Climate Action Plans
Miami is a national leader in resilience and sustainability planning, participating in diverse
initiatives to proactively address climate change. The Underdeck is in strong alignment with the
objectives and strategies in these plans:
• Southeast Florida Regional Climate Change Compact — partnership of Broward, Miami -
Dade, Monroe, and Palm Beach Counties, to reduce GHG emissions and build resilience.
• Resilient305 — a Miami -Dade County initiative, involving the Cities of Miami and Miami
Beach, addressing globalization and climate change.
• Miami Forever Climate Ready — Climate change adaptation strategy to reduce impact of
natural hazard. The Underdeck is aligned with these guiding principles and goals:
Principle #1-Maximize Multiple Benefits: Reducing greenhouse gases and heat island
effect; increase open space and shade; green stormwater management; improving public
health.
Goal 3: Protect and enhance our waterfront: correlate directly to Underdeck benefits
including: plantings of native species, creation of "sponge" areas for stormwater retention,
enhanced tree canopy and stormwater retention.
Goal 5: Promote adaptive neighborhoods and neighborhoods and buildings: Ensure park
access within a 10 minute walk by expanding Miami's overall park space from 7% to 15%.
• Miami Forever Carbon Neutral — Miami's Greenhouse Gas Reduction Plan (GHG Plan)
and roadmap for carbon neutrality by 2050 and a minimum 60% reduction in emissions by
2035, strengthen the local economy, and enhance climate justice.
Goal 1 Getting Around Miami Objective: 15% less private vehicle trips by 2035. The
Underdeck reinforces this strategy by offering multimodal alternatives (biking, walking) and
transit connection to reduce vehicle use.
Elements improving resilience
The South Florida region is at the forefront of climate -change concerns and climate resilience
planning. The Underdeck aligns with applicable goals and strategies in these plans to reduce GHG
emissions and achieve carbon neutrality by 2050. Additionally, the centrally located Heritage Trail
has nine paved areas with onsite power, broadband, water/sewer utilities, and comfort stations that
are designed for use as an emergency staging site to assist with disaster response and recovery for
adjacent communities during natural disasters.

• Mitigation of the identified Miami heat island effect by creating a 33-acre green urban oasis.
• Stormwater management approach for absorption of rainfall in planting areas and stormwater
purification, and detention of excess runoff within the site for flood mitigation (see Figure 17).
• Use of permeable walkway materials to increase rainfall absorption.
• Hardscape elements with efficient and low-cost maintenance, durability, and sustainability.
• Lighting designed in view of sun shading patterns. Project low energy, high efficiency LED
elements, reduce reliance on power supplies that may generate GHG.
• Softscape/plantings to decrease the use of hardscape materials and concrete unit pavers with a
longer product life to reduce long-term GHG emissions.
• Stimulating the use of active transportation modes in and around the corridor.
• Triggering mode shift from auto to bicycle and walking modes, with related GHG reduction.
Improvements to air and water quality, wetlands, and endangered species
Given the urbanized character of its footprint and vicinity, the Underdeck has essentially no adverse
impact on wetlands, endangered species, or air and water quality.
7. Workforce Development and Economic Opportunity
Local inclusive economic development and entrepreneurship
FDOT will be executing the construction phase of the Underdeck as part of the I-395 Connecting
Miami design -build project. Its contracting practices conform to Federal and state regulations and
Title VI/Civil Rights requirements (https://www. fdot. gov/equalopportunity/titlevi.shtm). FDOT's
robust Small Business Enterprise (SBE) program is structured to increase competition and provide
needed support to FDOT's work program.
The ongoing operations and maintenance of the Underdeck will be led by the City of Miami.
Programs and services offered at the Underdeck, including food, music, art festivals, farmer's
markets, vendor carts, and cultural activities will be competitively procured in accordance with
Miami's Procurement Code. This code includes language and applicability regarding Small
Business Enterprise and Local Workforce Participation requirements. All sub -leases of any space
in the Underdeck will be subject to the adoption and implementation of an affirmative action
Connecting Miami: I-395 Underdeck and Heritage Trail 16
plan. Promotional goals for minorities and women are established at all levels of the organization.
The Overtown Business Resource Center provides office space and technical assistance to small
businesses and residents within the SEOPW CRA boundaries. The OMNI CRA offers Business
Incentive Grants to new and existing businesses to expand employment opportunities. These
resources ensure inclusive opportunities for local businesses. Miami's Opportunity Center will
connect job seekers with job opportunities and employment resources to gain income at or above
a living wage.
Labor practices
The Underdeck construction will create 830 full-time jobs while the ongoing O&M is estimated
to create 82 full-time jobs paid in accordance with Miami's Living Wage Policy which applies
to employees and contractors. Jobs related to the maintenance, administration, programming,
public safety, and sanitation of the Underdeck (Figure 18) will be held by new and existing City
of Miami employees. Currently, the City maintains collective bargaining agreements with four
labor unions covering governmental workers (1,500 employees), police force (1,400 officers), fire
protection (800 members), and sanitation (200 members). Administrative Policies guide the City's
harassment, discrimination and equal opportunity policies and procedures.

Workforce development programs
Construction field can elevate job opportunities, showing that a transportation project can help
train, place, and retain the underrepresented community in good -paying jobs. Acknowledging its
socioeconomics, the City manages programs to develop the local workforce targeting businesses
and job seekers in low-income areas like Overtown: 1) Training & Certificates 2) Vouchers for
training/job access 3) Small Business Navigators 4) On -The -Job Training and paid apprenticeship;
and 5) Underemployed Navigators Readiness Program.
To address barriers to economic opportunities, FDOT contractors can leverage the Statewide
Workforce Development program, which has placed over 2,100 persons from its inception.
Florida's Statewide Workforce Development Program. With a 6-week training program offered by
contractors with support from FDOT, median annual income can increase from $19,000 to $31,000
(63%). FDOT's progressive Workforce Development Program (WDP) fosters training and skills.
The multifaceted program advances low-income workers to better jobs and careers and provides
opportunities through job -readiness training, the Correctional Transition Academy, Veterans
groups, Student Construction Internship and Student Construction Career Academy. The
program tracks placements, and publicizes available job openings.
In addition, FDOT and the City's construction procurement conforms to applicable Federal labor
Connecting Miami: I-395 Underdeck and Heritage Trail 17
and wage requirements on Federally -funded projects. FDOT's Equal Opportunity Construction
Contract Compliance Manual provides guidance on contract labor provisions.

Environmental Permits and Reviews: The Underdeck, as part of FDOT's Connecting Miami
project, has secured all required Federal NEPA clearances. The project was issued a Record of
Decision (ROD) on its FEIS on July 16, 2010. In addition, Reevaluations have been issued to
maintain currency of environmental approval (Appendix D). The highway component is at 60%
construction completion. All approvals and permits are secured.
Civic Support: Evidence of civic support is provided with the included Letters of Support.
STIP and TIP Funding Approvals: The project is approved for inclusion in the State TIP for
FY 2023/2024-2027-2028 as Project 251688 and the Miami -Dade TPO TIP (FY 2023/2024-2027-
2028 — Project ID DT2516701).
Risk and Mitigation: NEPA approvals and permits are secured. The project has confirmed
Federal planning consistency. FDOT maintains proper agency coordination during construction.
FDOT maintains a project field office to maintain citizen outreach, complementing the City's
further community coordination. All needed right-of-way is in place. The project will be built by
FDOT's design -build (D-B) contractor, resulting in no procurement delays. Cost contingencies
can be resolved by specifying alternate materials and deferring non -essential items. The D-B will
design and build the project, addressing change order issues. Underdeck work will occur mostly
off-street, minimizing traffic impacts. Construction delays will be managed by FDOT through its
D-B contract. In these ways, project risks appear minimal and/or manageable.

FACTSHEET
Connecting Miami:
1-395 Underdeck and Heritage Trail Project

The 1-395 Underdeck and Heritage Trail
The Underdeck is a planned public landscape that weaves below the elevated 1-395 roadway, creating a 33-acre
urban open space and streetscapes that will reunite the urban fabric of Overtown, a historically black
neighborhood that was disconnected during highway construction in the 1960s. A mile -long "Heritage Trail"
connects neighborhoods across active rail tracks, linking Overtown to Biscayne Bay, celebrating the diverse
cultural heritage of Miami, and establishing a unifying landscape destination for the City of Miami.
This forward -looking project with a cost of $82.7 million will provide a much -needed recreational green space for
the rapidly growing Center City population, transforming the public realm beneath the highway to a vibrant,
welcoming, and restorative community asset to enhance the mind, body, and spirit of users of all ages and
abilities. Key project elements include the Heritage Trail shared -use trail, extensive landscaping and urban tree
canopy, multiple play areas, interactive water features, a dog play area, amphitheater, sports courts, comfort
stations, and community -based public art installations.
Connecting Miami: I-395 Underdeck and Heritage Trail will provide a safe place for walking, jogging,
biking, and scooting, encouraging non -vehicular urban transportation options, while improving quality of life,
economic vitality, and social equity for all through the creation of an environmentally sustainable and resilient
urban landscape.
Background
The Connecting Miami: I-395/SR 836/1-95 Design Build Project is a partnership between the Florida Department of
Transportation (FDOT) and the Miami -Dade Expressway Authority (MDX). Highway improvements are located within the
City of Miami, extending from NW 17 Avenue on SR 836, through the SR 836/1-395/1-95 Midtown Interchange, out to the
MacArthur Causeway Bridge; additional improvements extend along 1-95 from NW 8 Street to NW 29 Street for pavement
replacement. The project is planned for completion in late 2027 at a cost of $840 million.
Acknowledging the historic impact of highway construction on Overtown and Miami's urban fabric, the project includes
the I-395 "Underdeckerdeck" — a public open space, created by an innovative structural design that raises the highway
and reduces columns for increased light and air. As a significant civic and community landscape, the City of Miami will
program, operate, and maintain the Underdeck featuring the Heritage Trail to serve as an everyday neighborhood
amenity for local communities and a destination for performances, events, and community celebrations.
Focus: Community I Safety I Mobility I Sustainability I Connectivity
The 1-395 Underdeck and Heritage Trail will:
Restore r"'JNECTIVITY to a neighborhood fractured by highway construction, which disproportionately affected
marginalized populations, reconnecting people and place along and across the corridor, and promoting more equitable
access to safe and affordable urban transportation options.
Transform COMMUNITY by reconstructing the "under the highway' urban barrier into an active public open space and
shared -use trail connecting 0vertown, Downtown, Arts & Entertainment District and Edgewater/Midtown.
Enhance SAFETY for pedestrians and bicyclists along and across the 1-395 corridor with the Heritage Trail, a bridge
crossing of the Florida East Coast Railway/Brightline tracks, and numerous enhanced pedestrian street crossings.
Increase MOBILITY for pedestrians and bicyclists along the east -west 1-395 corridor, as well as reconnecting
north -south neighborhoods and reinforcing bicycle routes and greenways within the City of Miami.
Promote SUSTAINABILITYthrough design and engineering that incorporates long-term durability and environmental
resiliency, while meeting community needs for green space and recreation that enhances neighborhood vitality.

PROJECT MERIT CRITERIA
• The Underdeck is designed to reconnect the urban fabric of Overtown,
transforming this historic barrier into a landscape that unifies the City of
Miami, promoting EQUITY and ENVIRONMENTAL JUSTICE through the
creation of a green open space with opportunities for respite and recreation, as
well as integrated pedestrian and bike routes, in a location that currently lacks
these amenities.
• The Heritage Trail follows Universal Design guidelines to create a space
that welcomes users of all ages and abilities. This new community will
be enhanced by wide pathways, traffic -calmed street crossings, three comfort
stations, lighting, and a broad pedestrian bridge crossing active FEC railroad
tracks. Multimodal connectivity will include bicycle lanes; greenways and trails;
micromobility hubs for rideshare and scooters; and walkable access to a full
hierarchy of local to intercity transit options as well as the free City trolleys.
• The Underdeck will replace the barren and uninviting "under the highway"
realm with a landscape designed for street -level neighborhood integration
and enhancement, a 'ACUITY WEii -Mil [TED to the community. The
highway is designed for enhanced clearances, rising from 25 feet by Biscayne
Bay to 60 feet in Overtown. Combined with a significant reduction in bridge
columns from 800 to 94, the open space will be flooded with light and air,
while providing shade from the tropical sun and cover from rain showers. The
Underdeck will replace the barren freeway space with an urban oasis
reconnecting neighborhoods at 5% of the cost of a freeway lid project.
• The open space corridor design is a COMMUNITY -CENTERED
featuring public art installations and memorials that
commemorate significant community figures and cultures. Site programming
was also driven by community input, achieving a mix of features that will
serve local residents and visitors. Key elements include interactive water
features, an amphitheater, play areas, a dog play area, comfort stations,
vending kiosks, diverse seating options, and drinking water stations for
people and pets. These features have been identified through extensive
community engagement, and funded through PARTNERING with FDOT and
two Community Redevelopment Authorities.
• The mile -long Heritage Trail will foster EQUITABLE DEVELOPMENT
north and south of the open space, and across the active FEC railway
tracks. It will facilitate mobility, unite neighborhoods through a shared
green network that enhances the urban environment and link community
spaces for the enjoyment of residents, workers and tourists alike.
• The Heritage Trail setting will feature lush landscaping with open lawns,
an expansive urban tree canopy that extends below the highway above.
Softscape is maximized through six planting palettes that are designed for
the range of site solar and hydrologic conditions, from"lush tropical"to"dry
succulents" Amenities along the trail include seat walls and benches,
signage and wayfinding, pathways of varying surfaces, and attractive
lighting, all adapted to Miami's , . ., . .
• This iconic project is essential for urban revitalization in a central and
rapidly developing area of Miami. It will serve as a legacy to all communities
who contributed to the creation of Miami, and it will stimulate dynamic
, creating new jobs, supporting local businesses,
and expanding the tax base for the residents of Overtown and Miami.
