SUMMARY ANALYSIS 
With 1,350 miles of coastline and relatively low elevations, Florida is particularly vulnerable to coastal flooding. 
One of the primary ways that climate change influences coastal flooding is through sea level rise. Sea level 
rise is an observed increase in the average local sea level or global sea level trend. Florida’s coastal 
communities are experiencing high-tide flooding events with increasing frequency because sea-level rise 
increases the height of high tides. In the United States, sea level rise and flooding threaten an estimated $1 
trillion in coastal real estate value, and analysts estimate that Florida could lose more than $300 billion in 
property value by 2100. 
 
Under current law, coastal construction is regulated by the Department of Environmental Protection (DEP) in 
order to protect beaches and dunes from construction that can jeopardize the stability of the beach-dune 
system, accelerate erosion, provide inadequate protection to upland structures, endanger adjacent properties, 
or interfere with public beach access. 
 
In 2020, the Legislature passed Senate Bill 178, which, beginning July 1, 2022, prohibits a public entity from 
commencing construction of certain state-funded coastal structures unless the entity has conducted a sea level 
impact projection (SLIP) study to assess risks to the structure. SB 178 directed DEP to adopt rules to develop 
a standard by which public entities must conduct the SLIP study and specified requirements for the standard. 
 
The bill expands the requirement for public entities to conduct a SLIP study before commencing construction of 
certain state-financed coastal structures to apply the requirement to certain structures that are within any area 
that is at risk due to sea level rise, not just coastal areas. The structures subject to this requirement are any 
“potentially at-risk structures or infrastructure,” which are defined as any major structures or infrastructure, 
including all infrastructure critical to public health, life, or safety, that are within an area at risk due to sea level 
rise. 
 
The bill may have an indeterminate fiscal impact on the state and local governments.

FULL ANALYSIS 
I.  SUBSTANTIVE ANALYSIS 
 
A. EFFECT OF PROPOSED CHANGES: 
Background 
 
Sea Level Rise and Coastal Flooding 
With 1,350 miles of coastline and relatively low elevations, Florida is particularly vulnerable to coastal 
flooding.
1
 One of the primary ways that climate change influences coastal flooding is through sea level 
rise.
2
 Sea level rise is an observed increase in the average local sea level or global sea level trend.
3
  
 
The two major causes of global sea level rise are thermal expansion caused by the warming of the 
oceans and the loss of land-based ice due to melting.
4
 Since 1880, the average global sea level has 
risen approximately eight to nine inches, and the rate of global sea level rise has been accelerating.
5
 
The National Oceanic and Atmospheric Administration (NOAA) utilizes tide gauges to measure 
changes in sea level and provides data on local sea level rise trends.
6
 Analysis of this data shows that 
some low-lying areas in the southeastern United States experience higher local rates of sea level rise 
than the global average.
7
 
 
Florida’s coastal communities are experiencing high-tide flooding events with increasing frequency 
because sea level rise increases the height of high tides.
8
 In the U.S., sea level rise and flooding 
threaten an estimated $1 trillion in coastal real estate value, and analysts estimate that Florida could 
lose more than $300 billion in property value by 2100.
9
 Sea level rise further affects the salinity of both 
surface water and groundwater through saltwater intrusion, posing a risk particularly for shallow coastal 
aquifers.
10
 Sea level rise also pushes saltwater further upstream in tidal rivers and streams, raises 
coastal groundwater tables, and pushes saltwater further inland at the margins of coastal wetlands.
11
 
 
Storm surge intensity and the intensity and precipitation rates of hurricanes are generally projected to 
increase,
12
 and higher sea levels will cause storm surges to travel farther inland and impact more 
properties than in the past.
13
 Stronger storms and sea level rise are likely to lead to increased coastal 
erosion.
14
 
 
Increases in evaporation rates and water vapor in the atmosphere increase rainfall intensity and 
extreme precipitation events, and the sudden onset of water can overwhelm stormwater

infrastructure.
15
 As sea levels and groundwater levels rise, low areas drain more slowly, and the 
combined effects of rising sea levels and extreme rainfall events are increasing the frequency and 
magnitude of coastal and lowland flood events.
16
 
 
State, Regional, and Local Programs 
Many state, regional, and local programs and policies are in place that address issues relating to sea 
level rise and coastal flooding. For example, the Office of Resilience and Coastal Protection within the 
Department of Environmental Protection (DEP) implements numerous programs related to sea level 
rise and coastal issues, including the Coastal Construction Control Line Program and the Beach 
Management Funding Assistance Program.
17
 DEP also implements the Florida Resilient Coastlines 
Program, which helps prepare coastal communities and habitats for the effects of climate change, 
especially sea level rise, by offering technical assistance and funding to communities dealing with 
coastal flooding, erosion, and ecosystem changes.
18
 
 
In 2021, the Legislature passed Senate Bill 1954 in an effort to address risks to the state posed by 
flooding and sea level rise.
19
 The bill directed DEP to develop a comprehensive statewide flood 
vulnerability and sea level rise data set and assessment.
20
 In addition, the bill required DEP to annually 
develop a statewide flooding and sea level rise resilience plan that consists of ranked projects totaling 
$100 million that address risks of flooding and sea level rise throughout the state.
21
 DEP must submit 
the plan to the Legislature for review and approval to fund the projects by December 1 of each year.
22
 
 
On the regional level, through a collaboration to address climate change, Broward, Miami-Dade, 
Monroe, and Palm Beach Counties formed the Southeast Florida Regional Climate Change Compact 
(Compact).
23
 The Compact’s work includes developing a Regional Climate Action Plan and developing 
a Unified Sea Level Rise Projection.
24
 Many local governments in southeast Florida have since 
incorporated the Compact’s projections into their planning documents and policies.
25
 
 
Florida’s local governments in coastal areas are required to have a coastal management element in 
their comprehensive plans that uses principles to reduce flood risk and eliminate unsafe development in 
coastal areas.
26
 In certain coastal areas, local governments are authorized to establish an “adaptation 
action area” designation in their comprehensive plan to develop policies and funding priorities that 
improve coastal resilience and plan for sea level rise.
27
 
 
Office of Resilience and Coastal Protection 
In January 2019, Governor DeSantis issued Executive Order 19-12, creating the Office of Resilience 
and Coastal Protection to help prepare Florida’s coastal communities and habitats for impacts from sea 
level rise by providing funding, technical assistance, and coordination among state, regional, and local 
entities.
28
 In August 2019, the Governor appointed Florida’s first Chief Resilience Officer, who reports to

Coastal Construction 
Under current law, coastal construction is regulated by DEP in order to protect Florida’s beaches and 
dunes from imprudent construction that can jeopardize the stability of the beach-dune system, 
accelerate erosion, provide inadequate protection to upland structures, endanger adjacent properties, 
or interfere with public beach access.
30
 Coastal construction is defined as any work or activity likely to 
have a material physical effect on existing coastal conditions or natural shore and inlet processes.
31
 
Florida’s coastal local governments may also establish coastal construction zoning and building codes 
in lieu of the statutory requirements as long as they are approved by DEP.
32
 
 
The coastal construction control line (CCCL) defines the portion of the beach-dune system that is 
subject to severe fluctuations caused by a 100-year storm surge, storm waves, or other forces such as 
wind, wave, or water level changes.
33
 A 100-year storm is a shore-incident hurricane or any other storm 
with accompanying wind, wave, and storm surge intensity that has a 1 percent chance of being equaled 
or exceeded in any given year.
34
 Seaward of the CCCL, new construction and improvements to existing 
structures generally require a CCCL permit from DEP.
35
 Due to the potential environmental impacts and 
greater risk of hazards from wind and flood, the standards for construction seaward of the CCCL are 
often more stringent than those that apply to the rest of the coastal building zone.
36
 Permit applicants 
must show that the proposed project will not result in a significant adverse impact.
37
 CCCLs are set by 
DEP on a countywide basis and are currently established for the majority of Florida’s coast.
38
 
 
The “mean high-water line” is the point on the shore that marks the average height of the high waters 
over a 19-year period.
39
 The mean high-water line is generally the boundary between the publicly 
owned foreshore (the land alternately covered and uncovered by the tide) and the dry sand above the 
line, which may be privately owned.
40
 Generally, construction is prohibited within 50 feet of the mean 
high-water line, known as the 50-foot setback.
41
 Any structures below the mean high-water line that are 
determined by DEP to serve no public purpose; to endanger human life, health, or welfare; or to be 
undesirable or unnecessary must be adjusted, altered, or removed.

Above the mean high-water line is the “seasonal high-water line,” which accounts for variations in the 
local mean high water, such as spring tides that occur twice per month.
43
 The seasonal high-water line 
is used to create 30-year erosion projections of long-term shoreline recession based on historical 
measurements.
44
 DEP makes 30-year erosion projections of the location of the seasonal high-water 
line on a site-specific basis upon receipt of a CCCL permit application.
45
 With certain exceptions, DEP 
and local governments may not issue CCCL permits for the construction of major structures that are 
seaward of the 30-year erosion projection.
46
 
 
The Coastal Zone Protection Act 
The Legislature enacted the Coastal Zone Protection Act of 1985 (act) to minimize the impacts that 
activities or construction near the coast have on Florida’s coastal areas.
47
 The act imposes strict 
construction standards in Florida’s coastal areas to protect the natural environment, private property, 
and life.
48
 The act applies to activities and construction within the coastal building zone, an area 
stretching landward from the seasonal high-water line to a line 1,500 feet landward from the CCCL.
49
 
 
The act generally requires construction to be located a sufficient distance landward of the beach to 
allow natural shoreline fluctuations and preserve dune stability.
50
 Nonhabitable major structures
51
 and 
minor structures
52
 must be designed to produce the minimum adverse impact on the beach and dune 
system.
53
 Minor structures must be designed to produce the minimum adverse impact to adjacent 
properties and reduce the potential for water- or wind-blown material.
54
 
 
At or prior to the time that a contract is executed for the sale of real property located partially or totally 
seaward of the CCCL, the seller must give a prospective purchaser a written disclosure statement that 
states the property may be subject to coastal erosion and to federal, state, and local regulations that 
govern coastal property.
55
 The disclosure statement must indicate that additional information can be 
obtained from DEP on whether significant erosion conditions are associated with the shoreline of the 
property being purchased.

Senate Bill 178 (2020) 
In 2020, the Legislature passed Senate Bill 178, which prohibited a public entity
56
 from commencing 
construction of a state-funded coastal structure
57
 unless the entity has conducted a sea level impact 
projection (SLIP) study, submitted the study to DEP, and received notification from DEP that the study 
was received and has been published on DEP’s website for at least 30 days.
58
  
 
The bill directed DEP to adopt rules to develop a standard by which public entities must conduct the 
SLIP study and specified that the SLIP study requirement would take effect one year after the rule 
became effective.
59
 DEP adopted rules in accordance with the bill that became effective July 1, 2021. 
Thus, the SLIP study requirement will take effect July 1, 2022.
60
 
 
The bill specified that the standard adopted by DEP rule must require the public entity to: 
 Use a systematic, interdisciplinary, and scientifically accepted approach in the natural sciences 
and construction design in conducting the SLIP study; 
 Assess the flooding, inundation, and wave action damage risks relating to the coastal structure 
over its expected life or 50 years, whichever is less; and 
 Provide alternatives for the coastal structure's design and siting, and how such alternatives 
would impact certain public safety and environmental risks as well as the risk and cost 
associated with maintaining, repairing, and constructing the coastal structure. 
 
The bill specifically required the risk assessment conducted by the public entity to: 
 Take into account potential relative local sea level rise and increased storm risk during the 
expected life of the coastal structure or 50 years, whichever is less, and, to the extent possible, 
account for the contribution of sea level rise versus land subsidence to the relative local sea 
level rise; 
 Provide scientific and engineering evidence of the risk to the coastal structure and methods 
used to mitigate, adapt to, or reduce this risk; 
 Use and consider available scientific research and generally accepted industry practices; 
 Provide the mean average annual chance of substantial flood damage over the expected life of 
the coastal structure or 50 years, whichever is less; and  
 Analyze potential public safety and environmental impacts resulting from damage to the coastal 
structure, including leakage of pollutants, electrocution and explosion hazards, and hazards 
resulting from floating or flying structural debris. 
 
The bill specified that the public entity is solely responsible for ensuring that the SLIP study submitted 
to DEP for publication meets these requirements and required DEP to publish and maintain a copy of 
all SLIP studies for at least 10 years after receipt. The bill required DEP to redact any information 
exempt from public record requirements before publishing the study. 
 
In addition, the bill specified that if multiple coastal structures are to be built concurrently within one 
project, a public entity may conduct and submit one SLIP study for the entire project. 
 
If a public entity commences construction of a coastal structure but has not conducted the SLIP study, 
the bill authorized DEP to institute a civil action to seek injunctive relief to cease further construction of 
the coastal structure or enforce compliance or, if the coastal structure has been completed or 
substantially completed, to seek recovery of all or a portion of the state funds expended on the coastal 
structure. 
 
                                                
56
 Section 161.551(1)(b), F.S., defines the term “public entity” to mean the state or any of its political subdivisions, or any 
municipality, county, agency, special district, authority, or other public body corporate of the state that is demonstrated to perform a 
public function or to serve a governmental purpose that could properly be performed or served by an appropriate governmental unit. 
57
 Section 161.551(1)(a), F.S., defines the term “coastal structure” to mean a major structure or nonhabitable major structure within the 
coastal building zone.

DATE: 1/25/2022 
  
Lastly, the bill specified that the failure to implement what is contained in the SLIP study does not 
create a cause of action for damages or otherwise authorize the imposition of penalties by a public 
entity. 
 
Effect of the Bill 
 
The bill expands the requirement for public entities to conduct a SLIP study before commencing 
construction of certain state-financed coastal structures to apply the requirement to certain structures 
that are within any area that is at risk due to sea level rise, not just coastal areas. The structures 
subject to this requirement are any “potentially at-risk structures or infrastructure,” which are defined as 
any major structures or infrastructure, including all infrastructure critical to public health, life, or safety, 
that are within an area at risk due to sea level rise.  
 
The bill defines an “area at risk due to sea level rise” as an area where sea level rise can substantially 
increase flood risk, including tidal, storm surge, riverine, runoff, stormwater, groundwater inundation, or 
coastal erosion. The bill specifies that an area at risk is any location that is projected to be below the 
threshold for tidal flooding
61
 within the next 50 years by adding sea level rise using the 2017 NOAA 
intermediate-high sea level rise projection.  
 
The bill revises the requirements for the SLIP study standard that a public entity must use by specifying 
that the required risk assessment must provide an estimated probability of significant flood damage to 
the structure or infrastructure. The bill also revises the definition of “significant flood damage” to specify 
that it means flood, erosion, inundation, or wave action damage resulting from a discrete or compound 
natural hazard event, such as a flood or tropical weather system, where such damage exceeds: 
 25 percent of the replacement cost of the structure or infrastructure at the time of the event; or 
 A defined threshold established by DEP in coordination with the Department of Transportation 
and water management districts. The threshold must be established by July 1, 2023. 
 
The bill also requires the risk assessment to provide a list of flood mitigation strategies evaluated as 
part of the design of the structure or infrastructure and identify flood mitigation strategies that have 
been implemented or are being considered as part of the structure or infrastructure design. 
 
B. SECTION DIRECTORY: 
Section 1.  Amends s. 161.551, F.S, relating to public financing of construction projects within areas 
at risk due to sea level rise. 
 
Section 2. Provides an effective date of July 1, 2022. 
 
II.  FISCAL ANALYSIS & ECONOMIC IMPACT STATEMENT 
 
A. FISCAL IMPACT ON STATE GOVERNMENT: 
 
1. Revenues: 
None. 
 
2. Expenditures: 
The bill may have an indeterminate negative fiscal impact on state government in the short-term 
because the bill requires governmental entities to conduct a SLIP study prior to construction of 
certain structures. However, the SLIP study will identify risks that could potentially avoid damage 
and loss of structures that were constructed using state funds, so the bill may result in an 
indeterminate positive fiscal impact to state government in the long-term.

 The bill specifies that the threshold for tidal flooding is 2 feet above mean higher high water.  STORAGE NAME: h1077a.EAF 	PAGE: 8 
DATE: 1/25/2022 
  
The bill may have an indeterminate negative fiscal impact on DEP because it requires DEP to 
conduct rulemaking and implement new regulations. DEP can likely implement the rulemaking and 
new regulations within existing resources. 
 
B. FISCAL IMPACT ON LOCAL GOVERNMENTS: 
 
1. Revenues: 
None. 
 
2. Expenditures: 
The bill may have an indeterminate negative fiscal impact on local governments because the bill 
requires governmental entities to conduct a SLIP study prior to construction of certain structures. 
However, the SLIP study will identify risks that could potentially avoid damage and loss of those 
structures, so the bill may result in an indeterminate positive fiscal impact to local governments in 
the long-term. 
 
C. DIRECT ECONOMIC IMPACT ON PRIVATE SECTOR: 
None. 
 
D. FISCAL COMMENTS: 
None. 
III.  COMMENTS 
 
A. CONSTITUTIONAL ISSUES: 
 
 1. Applicability of Municipality/County Mandates Provision: 
The county/municipality mandates provision of Art. VII, section 18, of the Florida Constitution may 
apply because this bill requires counties and municipalities that use state funds to build a structure in 
an area at risk of sea level rise to conduct a SLIP study before commencing construction. However, 
an exemption may apply if the bill results in an insignificant fiscal impact to county or municipal 
governments. 
 
 2. Other: 
None. 
 
B. RULE-MAKING AUTHORITY: 
The bill would require DEP to revise its rules regarding SLIP studies for state funded structures. 
 
C. DRAFTING ISSUES OR OTHER COMMENTS: 
None. 
 
IV.  AMENDMENTS/COMMITTEE SUBSTITUTE CHANGES 
None.
