TODAY’S PLAN

GROUND1OVERVIEW 3OPTIONS 4 NEXT STEPS:
-POLICY
-BUDGET
Is the capacity of individuals,
communities, institutions,
businesses, and systems
within a city to
survive, adapt, and grow
no matter what kinds
of chronic stresses and
acute shocks they
experience.
URBAN
RESILIENCE?
4
What are
shocks + stresses?
Stresses weaken the fabric of a city
on a daily or cyclical basis such as:
•Pronounced Poverty
•Overtaxed + Underdeveloped
Transportation System
•Aging Infrastructure
•Lack of Affordable Housing
•Rising Sea Level + Coastal
Erosion
Shocks are sudden, sharp
events that threaten a city such
as:
•Hurricanes/Tornados
•Coastal Flooding
•Infrastructure Failure
•Cyberterrorism
•Heat wave
•Disease Outbreak 5

CHIEF RESILIENCE
OFFICER ROLE
1.Works across departments to improve internal communications,
address complexities, promote new collaboration, promotes
synergy between projects and plans that departments are drafting.
2.Bring together stakeholders, including government officials, private
sector, non-profits, etc.
3.Leads the resilience strategies-full of resilience building initiatives
to put into action.
4.Acts as the “resilience point person,” ensuring that the city applies
a resilience lens so that resources are leveraged holistically and
projects planned for synergy. This lets the city get the most “bang
for its buck” on its projects, potentially achieving multiple resilience
goals with one project.

What is your vision?
8
A resilience strategy is the product of a process during which a city
develops a better understanding of the challenges it faces; reviews its
ability to address those challenges; and unites people, projects, and
priorities, so that cities can collectively act on their resilience challenges

FEMA CRS Score
Improvement
Flood insurance is an important issue for Miami
Beach, since 93% of buildings are in the Special
Flood Hazard Area.
•Residents and businesses save $8.4 million annually on
flood insurance premiums through the City of Miami
Beach’s participating in the National Flood Insurance
Program Community Rating System (CRS) Program
•As the federal government proposes changes to the
National Flood Insurance Program, Miami Beach
residents and businesses are likely to be impacted.
Mitigation and adaptation are important ways to reduce
risk and the cost of insurance.

PROJECT MANAGEMENT
& PERMITTING
How can we improve project execution to finish projects
faster and more cost effectively? What are the options
for a smoother design, permitting, harmonization and
construction process? Integrating successes and lessons
learned into future projects.
Eric Carpenter, Assistant City Manager
6
Looking Back
Palm & Hibiscus Islands Experience
Mistakes were made by city and design/build contractor on this
project regarding scope, permitting and coordination
After project was under construction, several changes occurred:
•City issued new drainage policy directives (twice)
•Addition of generators at request of HOA
•Change in roadway design to accommodate undergrounding at
request of HOA
•Lighting modifications at request of HOA
•Modified landscaping at request of HOA
69
Harmonization Efforts
70
Lessons Learned
•Design and agree on individual property harmonization details
before construction begins
•Limit changes of construction scope once construction begins
•Emphasize responsibilities of contractor with regards to
permits prior and throughout the project
•Construction of projects on behalf of other governmental
entities will be avoided
•HOA/community direction may differ
71
72
“Overall, given sea level rise and the uncertainties of the escalation of
higher tides in the future, we believe raising our roads on Palm and
Hibiscus Islands where needed and adding pump stations (with back up
generators) for our Islands was a prudent and good decision.”

WATER QUALITY
What are our water quality issues (perceived, reality, regulatory)? How can
we improve water quality, address community concerns related to
stormwater pumps? How can we do our part to improve water quality locally
and regionally?

Water Quality Monitoring
The county samples the Bay monthly and releases
an annual report.

In 2016, the city voluntarily launched
a Bay monitoring program.
96
The DOH samples beaches to ensure they are
swimmable.

2020 Water Quality
Goals & Opportunities
GOAL 1
Increase recreational user awareness of water quality conditions in swimmable waters on the
beaches and the bay.
•OPPORTUNITY: Add DOH sampling stations where testing is not currently conducted to inform
recreation (i.e., Purdy boat ramp).
GOAL 2
Continue to reduce construction run-off into the stormwater system through increased training and
enforcement.
•OPPORTUNITY: Provide more frequent training across city departments.
•OPPORTUNITY: Assign second inspector dedicated to monitoring private construction sites.
GOAL 3
Reduce the volume of nutrients going into Biscayne Bay across the region.
•OPPORTUNITY: Urge County to adopt countywide fertilizer ban. Resolution going to Commission
in March.
The Administration has identified
six goals and opportunities.
99
GOAL 4
Implement blue and green infrastructure elements of the Jacobs Engineering
integrated water management plan.
•OPPORTUNITY: Apply for grants (i.e., State water quality grant for Everglades
Court Green Alley) that leverage city funds for the construction of blue/green
elements.
GOAL 5
Increase public awareness of individual impact on water quality and steps each
person can take to further reduce pollution at the source.
•OPPORTUNITY: Launch 2020 water quality educational campaign.
GOAL 6
Leverage work across the region to reduce pollution at a larger scale.
•OPPORTUNITY: Expand Plastic Free MB to Plastic Free 305.
The Administration has identified
six goals and opportunities.

How can we transition our public and private seawalls
over time? What can we do to address seawall
overtopping and convene financing options? How can the
city require, encourage, and incentivize private property
adaptation?

Historic Preservation
Fund Update
•Idea for historic preservation fund included in
North Beach Master Plan
•Referred to Finance & Resiliency Committee at
April 11, 2018 City Commission meeting
•Goal: encourage preservation, restoration,
rehabilitation, and climate adaptation activities to
contributing historic resources
•Engaged consultant, Keith & Schnars; recently
conducted analysis of Planning’s fee schedule
o Research programs in other cities
o Develop potential program framework
o Identify potential funding sources
o Consultant expects to present recommendations at
February 21st Finance & Economic Resiliency
Committee
114
NEXT STEPS
•Resiliency Code –The administration is finalizing the contract negotiations with the
top ranked firm and expects work to begin on the new Resiliency Code in the spring.
•Commercial First Floor Elevation Standards –A comprehensive set of
recommendations will be brought to the Land Use and Sustainability Committee on
March 17, 2020 for review and recommendation.
•Resilience FAR-A comprehensive discussion pertaining to FAR is scheduled for the
February 18, 2020 Land Use and Sustainability Committee, and will include potential
FAR bonuses for meeting resiliency and sustainability benchmarks.
•Basements-Currently the City Code allows basements, subject to compliance with all
Florida Building Code Regulations. The administration continues to have concerns
with allowing new basements and recommends that the item be further studied
either as a new referral to the Land Use and Sustainability Committee, or as part of
the drafting of a new Resiliency Code.

STORMWATER MANAGEMENT
& CLIMATE ADAPTATION REVIEW
“The city acted with courage to fix sunny-day
and stormwater flooding...
•Applied good practice for initial stormwater pump
rollout and street elevations.
•Designed using climate change risk estimates, using
climate change projections from the Southeast
Florida.
•Raised funds through fees and bonds rather than
federal and state programs.
•Preserving property values is critical to ensure
funding”

FUNDING
How do we best allocate resources? What
has the city spent (to-date) and what are the
future needs and sources for the stormwater
program, sea walls, private property
adaption/ historic preservation fund, water
and sewer infrastructure, short term
temporary pumps and staffing? What are the
potential operating costs and fee increases?
Grant opportunities?
