and
Private Property
Flooding and Sea Level Rise
Resilience Program Concept

Item R7 I

Resiliency Fund Overview
1.Create a Resiliency Fund from the
earmarked Miami-Dade ILA fund for
stormwater capital projects
2.Allocate funding from the Resiliency Fund
for the private property program until the
future Convention Center Hotel is built.
($666,666 annually until rent is received)
3.Private Property Adaptation would be a
new grant program and staff resources
needed to implement grant program in
the FY 2021-2022 Budget

Inform, Prepare, Adapt
•Miami Beach is low-lying, and 93% of all buildings are
in the FEMA Special Flood Hazard Area. 43% of
residents are satisfied with their buildings’ flood risk
protections (2019 Community Survey).
•The Unified Regional Sea Level Rise Projection 2019
developed by the Southeast Florida Climate Change
Compact highlights the need to prepare for
increased flooding (NOAA, IPCC)
•Being proactive makes financial sense
o Every dollar invested saves three dollars in individual
building level adaptations (ICF Miami Beach analysis)
o Every dollar invested saves five dollars in individual building
level adaptations (Southeast Florida Climate Change
Compact and Urban Land Institute Miami-Dade Analysis)
o Every dollar invested saves society six dollars disaster
mitigation by three federal agencies (NIBS)

Land Use and Sustainability Committee: Direction to staff
to develop a Private Property Adaptation Program
How was the program concept developed?
1.Best practice research from other cities
2.Interdisciplinary staff approach: expertise, grant program resource requirements,
preliminary criteria
3.Market research: 10 companies interviewed to understand the options available for
private properties.
4.Questionnaire: Options included in a questionnaire distributed through city
communications channels: 416 responses
•50% indicated they have observed flooding on the lawn (27%), in the garage (27%) and habitable areas
(13%)
•77% responded they would apply for a 50/50 matching grant if offered

•Menu of potential practical and
implementable flooding resilience
improvements.
•Expert professional staff panel, points based
on criteria.
