COMMITTEE SUBSTITUTE - Substantial Changes 
 
I. Summary: 
CS/SB 298 amends the Resilient Florida Grant Program to authorize the Department of 
Environmental Protection (DEP) to provide grants to coastal counties to conduct vulnerability 
assessments analyzing the effects of saltwater intrusion on their water supplies and the 
preparedness to respond to such a threat. Each vulnerability assessment must include an analysis 
of all of the following information: 
 The coastal county’s primary water utilities; 
 Current maps of the coastal county’s freshwater wellfields and latest saltwater intrusion 
impact lines; 
 Projections of saltwater intrusion over the next decade, including specific wells that may be 
impacted during that timeframe; and 
 The costs necessary to relocate freshwater wellfields that are anticipated to be impacted, 
including current projects that are underway to relocate the freshwater wellfields. 
 
The bill also requires DEP to do all of the following: 
 Use the information contained in a coastal county’s saltwater intrusion vulnerability 
assessment to update its Comprehensive Statewide Flood Vulnerability and Sea Level Rise 
Data Set;  
 Make publicly available on DEP’s website any appropriate information from a saltwater 
intrusion vulnerability assessment it receives from coastal counties; and 
 Provide 50 percent cost-share funding up to $250,000 for each grant awarded under this 
section of the Resilient Florida Grant Program. A coastal county with a population of 50,000 
or less is not required to contribute to the cost share.  
REVISED:   BILL: CS/SB 298   	Page 2 
 
In addition, the bill provides that a coastal county or coastal municipality may not establish local 
coastal construction zoning and building codes unless such zones and codes were approved in 
writing by the Department of Environmental Protection (DEP) on or before December 1, 2023, 
and exceptions to such locally established zones and codes may not be granted unless approved 
by DEP before December 1, 2023. The bill also provides that DEP may not delegate authority for 
permitting certain activities to a coastal county or coastal municipality that did not receive local 
coastal construction zoning and building code exceptions to the coastal control line on or before 
December 1, 2023. 
II. Present Situation: 
Saltwater Intrusion 
Drinking water in Florida comes primarily from water found within underground layers of water-
bearing rock or sand called aquifers.
1
 Aquifers are composed of different types of sediments and 
rocks, such as gravel, sandstone, and limestone.
2
 Groundwater enters an aquifer as precipitation 
seeps through the soil and can move through the aquifer and resurface through springs and 
wells.
3
 Fresh and salt water fill the holes in the rock, with freshwater generally filling the 
uppermost part of aquifers and saltwater found at greater depths.
4
  
 
Under natural conditions, the seaward movement of freshwater prevents seawater from 
encroaching coastal aquifers.
5
 When groundwater is pumped from a coastal aquifer, lowered 
water levels can cause seawater to be drawn toward the freshwater zones of the aquifer. The 
intruding seawater decreases the freshwater storage in the aquifers. Without treatment, this 
groundwater does not conform to drinking water or agricultural water quality standards.

Saltwater intrusion can occur in various ways, including lateral encroachment from coastal 
waters and vertical movement of saltwater near discharging wells.
7
 It can be caused by digging 
wells too deep, excessive groundwater pumping, sea level rise, severe drought,
8
 king tides, and 
storm surge.
9
 Sources include infiltration from tidal marshes, estuaries, and bays, encroachment 
from the ocean, leakage from unprotected canals, upward leakage from deeper aquifers, and 
movement of residual saltwater.
10
 Rising sea levels also push saltwater upstream in tidal rivers 
and streams, raise coastal ground water tables, and push saltwater further inland.
11
 
 
Saltwater intrusion can cause serious consequences in terms of both environmental and economic 
impacts. Potable water is necessary for drinking, irrigation, and most industrial uses,
12
 but the 
intrusion of saltwater into coastal aquifers can increase groundwater salinity beyond potable 
levels, endangering access to freshwater for millions of people.
13
 Even small changes in salinity 
can render water undrinkable—chloride concentrations above 250 milligrams per liter (salinity 
of approximately 0.5 parts per thousand) can cause hypertension and stroke.
14
  
 
Saltwater intrusion can also negatively affect local agriculture. The vast majority of 
commercially grown tropical fruits and vegetables and most landscape ornamental plants have

little to no salinity tolerance.
15
 Saline soil and/or salty irrigation water can result in mild to lethal 
physiological effects, including reduced cell growth and plant organ (e.g., leaf and fruit) 
expansion, reduced water and nutrient uptake, nutrient imbalances and deficiencies, reduced 
plant growth and yields, and plant death.
16
 This results in increased production costs and 
decreased product sales.
17
   
 
In addition, saltwater intrusion can cause a decline in forest productivity. Saltwater degrades 
coastal wetlands and barrier islands, which buffer inland areas from storm surge, by killing less 
salt-tolerant species and leaving behind “ghost forests” or wetland areas with only standing dead 
trees.
18
 Over time, saltwater intrusion, along with rising sea levels, convert these diverse wetland 
ecosystems into grass marshes and eventually into open water. The loss in forest and agricultural 
productivity due to increased soil salinity results in decreased ecosystem diversity and habitat for 
birds, fish, and the animals that prey on them.
19
 Moreover, studies show that salt buildup in the 
soil increases greenhouse gas emissions, contributing to climate change and global warming.
20
 
 
Several assessments have been prepared regarding the impact of sea level rise on water 
resources. For example, the South Florida Water Management District has evaluated saltwater 
intrusion in the surficial aquifer system of the Big Cypress Basin and southwest Florida
21
 and 
mapped the saltwater interface in coastal aquifers within St. Lucie, Martin, Palm Beach, 
Broward, Collier, and Lee counties.
22
 The U.S. Geological Survey conducts saltwater interface 
mapping for Miami-Dade and Monroe counties.
23
 At least one evaluation of Florida’s saltwater 
intrusion monitoring network has been performed.
24
 In addition, the Northwest Florida Water 
Management District has commissioned a report evaluating saltwater intrusion in the Floridan 
Aquifer in Walton, Okaloosa, and Santa Rosa counties.

Statewide Resilience Programs 
The Legislature has established several statewide resilience programs, including:  
 The Resilient Florida Grant Program, which provides grants to counties or municipalities for 
community resilience planning, including vulnerability assessments, plan development, and 
projects to adapt critical assets.
26
 In the programs first two years, 263 implementation 
projects have been awarded a total of nearly $954 million.
27
  
 The Comprehensive Statewide Flood Vulnerability and Sea Level Rise Data Set and 
Assessment.
28
 In May 2023, DEP published a statewide data set containing an inventory of 
critical and regionally significant assets (such as transportation, critical infrastructure and 
emergency facilities), topographical data (including digital elevation models and survey 
data), and flood scenario data (including data regarding precipitation, land use, and 
groundwater elevation).
29
 DEP is also tasked with developing a statewide assessment 
providing statewide sea level rise projections and information necessary to determine the 
risks of flooding and sea level rise to inland and coastal communities. DEP must update the 
data set and assessment every five years.
30
 The statewide assessment and data set must be 
updated every five years.
31
 
 The Statewide Flooding and Sea Level Rise Resilience Plan, which consists of ranked 
projects that address risks of flooding and sea level rise to coastal and inland communities.
32
 
Examples of projects include construction of living shorelines, seawalls, and pump stations, 
elevation projects, and infrastructure hardening.
33
 Counties, municipalities, water 
management districts, regional water supply authorities, and other entities may submit to 
DEP an annual list of proposed projects. In December 2022, DEP submitted the FY 23-24 
Statewide Flooding and Sea Level Rise Resilience Plan totaling nearly $408 million over the 
next three years.

 The Florida Flood Hub for Applied Research and Innovation,
35
 which was established within 
the University of South Florida College of Marine Science to coordinate efforts between the 
academic and research institutions of the state.
36
 The Florida Flood Hub is tasked with, 
among other things, organizing existing data needs for comprehensive statewide flood 
vulnerability and sea level rise analyses and performing gap analyses to determine data 
needs; developing statewide open source hydrologic models for physically based flood 
frequency estimation and real-time forecasting of flood; establishing community-based 
programs to improve flood monitoring and prediction along major waterways; and providing 
tidal and storm surge flooding data to counties and municipalities for vulnerability 
assessments.
37
  
 
DEP may also provide funding for regional resilience entities to assist local governments with 
planning for the resilience needs of communities and coordinating intergovernmental solutions to 
mitigate adverse impacts of flooding and sea level rise.
38
 As of February 2023, $4 million had 
been appropriated to regional resilience entities to date.
39
 
 
The Statewide Office of Resilience reviews flood resilience and mitigation activities in the state 
and coordinating flood resilience and mitigation efforts with federal, state, and local 
governmental entities and other stakeholders. The office’s Chief Resilience Officer and DEP 
worked together to provide the Governor and Legislature with a report on flood resilience and 
mitigation efforts across Florida. The report includes: 
 A list of local governments that are required to comply with the requirements of s. 
163.3178(2)(f), F.S.,
40
 but are not in compliance, as reported by the Department of Economic 
Opportunity; 
 A list of local governments that have completed vulnerability assessments in compliance 
with the requirements of the Resilient Florida grant program in s. 380.093(3), F.S.;
41
 
 An overview of the geographic distribution of entities with funded projects in the Statewide 
Flooding and Sea Level Rise Resilience Plan;

Coastal Construction Permits 
Coastal construction permits protect Florida’s beaches and dunes from imprudent construction 
that may jeopardize the stability of Florida’s natural resources.
46
 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.
47
 Seaward of the CCCL, new construction and improvements to existing 
structures require a CCCL permit from DEP.
48
 The line defines the landward limit of DEP’s 
authority to regulate construction.
49
 DEP’s CCCL Program regulates structures and activities 
which can cause beach erosion, destabilize dunes, damage upland properties, or interfere with 
public access.
50
 CCCLs currently exist for large portions of Florida’s coast.
51
 
 
A coastal county or coastal municipality may establish coastal construction zoning and building 
codes if such zones and codes are approved by DEP as being adequate to preserve and protect 
the beaches and coastal barrier dunes adjacent to such beaches from imprudent construction that 
will 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.
52
 Exceptions to locally established coastal construction zoning and building codes may 
not be granted unless previously approved by DEP. The intent is to provide for the local 
administration of established CCCLs through approved zoning and building codes if desired by 
local interests and where such local interests have sufficient funds and personnel to adequately 
administer the program. If DEP determines at any time that the program is inadequately 
administered, DEP may revoke the authority granted to the county or municipality.
53
 
 
DEP may delegate authority for permitting certain types of activities to a coastal county or 
coastal municipality.
54
 Such partial delegation must be narrowly construed to those particular 
activities specifically named in the delegation and agreed to by the affected county or 
municipality. DEP may revoke the delegation at any time if it is determined that the delegation is 
improperly or inadequately administered.
55
 
III. Effect of Proposed Changes: 
Section 1 amends s. 161.053, F.S., regarding coastal construction and excavation. The bill 
provides that a coastal county or coastal municipality may not establish coastal construction

Department of Environmental Protection (DEP) on or before December 1, 2023, and exceptions 
to such locally established zones and codes may not be granted unless approved by DEP before 
December 1, 2023. The bill also provides that DEP may not delegate authority for permitting 
certain activities to a coastal county or coastal municipality that did not receive local coastal 
construction zoning and building code exceptions to the coastal control line on or before 
December 1, 2023. 
 
Section 2 amends the Resilient Florida Grant Program, s. 380.093, F.S., to authorize DEP, 
beginning July 1, 2025, to provide grants to coastal counties to conduct vulnerability assessments 
analyzing the effects of saltwater intrusion on their water supplies and the preparedness to 
respond to such a threat. 
 
Each vulnerability assessment must include an analysis of all of the following information: 
 The coastal county’s primary water utilities; 
 Current maps of the coastal county’s freshwater wellfields and latest saltwater intrusion 
impact lines; 
 Projections of saltwater intrusion over the next decade, including specific wells that may be 
impacted during that timeframe; and 
 The costs necessary to relocate freshwater wellfields that are anticipated to be impacted, 
including current projects that are underway to relocate the freshwater wellfields. 
 
The bill requires DEP to do all of the following: 
 Use the information contained in a coastal county’s saltwater intrusion vulnerability 
assessment to update its Comprehensive Statewide Flood Vulnerability and Sea Level Rise 
Data Set;
