PROPOSED REVISIONS TO
COASTAL MANAGEMENT ELEMENT
Comprehensive Plan Coastal Management Element
These counterclockwise -rotating, extreme low pressure storms can reach ten miles in height, can
spread over several hundred miles in diameter, and can generate winds in excess of 74 miles per hour
(MPH), the minimum wind speed necessary to be classified as a hurricane. The official hurricane
season extends from June 1 st to November 30th, with 62 percent of all Florida hurricanes occurring
during September and October.
While extensive rainfall commonly occurs during a hurricane and may cause widespread inland
flooding, the greatest danger associated with a hurricane is storm surge. Storm surge can be
described as the rise in wave and tidal heights associated with a hurricane. The vulnerability of an
area to storm surge is dependent upon the potential height that a storm surge can achieve along a
particular coast and the distance to which the surge can penetrate inland upon making landfall. Thus,
low-lying coastal topography, such as inlets, beaches and estuaries, are especially susceptible to the
destructive forces of a storm surge (Hurricane Manual for Marine Interests in Indian River County).
• Coastal High Hazard Area
The Coastal High Hazard Area (CHHA) is defined as the area below the storm surge line of a
Category 1 hurricane as established by a Sea, Lake, and Overland Surges from Hurricanes (SLOSH)
computer model. The CHHA is depicted in figure 9.11.
As of 2018, Indian River County has also designated the CHHA as an "Adaptation Action Area"
(AAA) in accordance with Section 163.3164(1) KS and in support of Objective 15 of this Element
and its associated policies. An AAA is defined as one or more areas that experience coastal flooding
due to extreme high tides and storm surge, and that are vulnerable to the related impacts of rising sea
levels for the purpose of prioritizing funding for infrastructure needs and adaptation planning.
Within the CHHA, most of the land is designated for residential use, with permitted densities
ranging from 3 to 10 units per acre. A substantial portion of this land is currently developed. Much
of that development took place at a time when the CHHA was more narrowly defined as land on the
barrier island, east of the Coastal Construction Control Line (CCCL).
• Hurricane Vulnerability Zone
Although many areas are subject to coastal flooding associated with the severe weather of hurricanes,
other areas face imminent danger from the storms. Those areas which face severe erosion, flooding,
storm surge, or other direct storm related damages from a Category III hurricane constitute the
Hurricane Vulnerability Zone (HVZ). The HVZ is depicted in Figure 9.12. This zone has been
identified for special planning and evacuation purposes.
• Comprehensive Emergency Management Plan
In accordance with Chapter 252, F.S., Indian River County has adopted a Comprehensive Emergency
Management Plan (CEMP). The CEMP replaces the Peacetime Emergency Plan (PEP), the Florida
Community Development Department Indian River County 17
APPENDIX A
Comprehensive Plan Coastal Management Element
Line" (D.S.S.L.). Other than approved dune walkovers, minor structures or erosion control projects,
construction is not allowed seaward (east) of this regulatory line.
Within Indian River County, the Coastal Barrier Resource Act (CoBRA) recognizes and discourages
development in two areas: an area south of Ambersand Beach on the northern portion of the barrier
island; and an area in the southern portion of the barrier island near the Indian River - St. Lucie
County line.
Because these relatively undeveloped areas are recognized as having the greatest potential for storm
damage, federal flood insurance is unavailable in these areas. Should a Category V storm event
occur, much of the barrier island and particularly the areas identified by CoBRA could be completely
destroyed.
Even with significant measures in place to reduce potential storm damage, hurricanes Francis and
Jeanne in 2004 caused wide -spread damage to structures along the beach as well as structures inland.
Sea Level Rise
Sea level rise (SLR) is typically defined in terms of either global (eustatic) sea level rise or relative
sea level rise. Global sea level rise represents the average change in the height of all of Earth's
oceans relative to the land. Conversely, relative sea level rise refers to measured changes in sea level
height at specific locations on land relative to localized variations in land elevation, including
changes due to ocean rise and/or land subsidence.
Global sea level rise is directly influenced by fluctuations in the mass or volume of the ocean.
Fluctuations in the volume of the ocean are the result of climatological and geological forces such as
thermal expansion and contraction, tectonic shift, lift/subsidence, and sedimentation, while ocean
mass is affected by factors including melting or accretion rates of glaciers, snow accumulation, and
global water storage and redistribution mechanisms. Based on the Intergovernmental Panel on
Climate Change (IPCC) Fifth Assessment Report (ARS,), many of these climate related phenomena
have been directly influenced by greenhouse -gas emissions increases since the pre -industrial era and
other feedback mechanisms. With respect to SLR, the IPCC AR5 indicates that global average land
and ocean surface temperatures will likely continue to increase and contribute to the acceleration of
SLR encountered in the future.
In Florida, baseline relative sea level.measurements can be derived from historical tide gauge records
of mean monthly sea level. In fact, average monthly sea level measurements have been recorded at
tide stations located in Key West, Cedar Key, and Fernandina Beach .for more than a century. The
yeaLlv averages of these historic data, depicted in Figure 9.14, indicate a gradual trend of rising mean
sea level between 1.897 and 2017. Moreover, these data highlight regional variability that may be
observed among local relative sea level datasets. Based on those data sets, sea levels at Key West,
Cedar Key, and Fernandina Beach rose approximately 12.72", 12.66", and 15.63" over the last 100
years.

Regional mapping and vulnerability assessment studies related to sea -level rise. (SLR) .were initially
developed by federal, state, .and local government agencies in the early 2000s.. Circa 2009,
development of consistent regional climate change adaptation strategies became the basis for
formation of the Southeast Florida Regional Climate Change Compact (SFRCCC), which was
represented by four coastal counties, Monroe, Miami -Dade, Broward, and Palm -Beach. The
SFRCCC created a Unified Sea Level Rise Projection for Southeast Florida in 2011 based on U.S.
Army Corps of Engineers Engineering Circulars guidance documents, historical tidal data from Key.
West (1913-1999), and.available scientic literature on the subject at the time. This Unified SLR
Projection was later revised in 2015 based on updated guidance documents from USACE, NOAH,
and the United Nations Intergovernmental Panel on Climate Change (IPCC(Figure 9.15). .
According to the revised projection the region may experience between 14 and 34 inches of sea level
rise (above 1992 mean sea leveD by 2060.

Moreover, other data comparisons were evaluated in the analysis including taxable property value
ranges impacted based on inundation level, degree of impacts to higher and lower functional
classification roads, and total acres impacted based on future land use designation. Those baseline
data provided critical insights for implementation of long range adaptation planningstrate lg_es.
ANALYSIS
Land Use
This analysis section addresses issues, problems, and opportunities within the coastal zone. A
complete analysis of land use data, including a comparison of land use acreages by classification, is
contained in the Future Land Use Element of the Comprehensive Plan.
In the past, comprehensive plan policies, including the Future Land Use Map, have successfully
directed new residential and nonresidential development to designated areas of the county.
Consequently, there have been few amendments to the land use map and only minor adjustments to
the county's Urban Service Area boundary since the county's current comprehensive plan was
adopted in 1990. In fact, the only significant changes to the Future Land Use Map in the previous
decade have been amendments designating publicly acquired environmental lands for conservation.
Going forward, the major land use issues facing Indian River County in the coastal zone and in the
county overall are urban sprawl, rural sprawl, agricultural preservation, and conservation of natural
systems within the context of development.
Economy
Generally, the county's economy is limited in diversity and largely reliant on service oriented
industries. Despite this current lack , of economic diversity, Indian River County has attractive
qualities that certain businesses look for. These qualities, which include an available development -
ready supply of land and an exceptional quality of life (warm weather, beaches, minimal population
density, resource-based recreational opportunities, etc.), will aid the county as it seeks to increase its
economic base in the future.
• Eco Tourism
A significant aspect of the County's quality of life is its natural resources, not the least of which is
the Indian River Lagoon. Resources such as the lagoon provide significant economic benefits to the
county. According to the Indian River Lagoon Economic Assessment and Analysis Update (2007),
the total economic impact in 2007 of visitors to the Indian River Lagoon in Indian River County was
over $110 million.
Because of its natural assets, as well as cultural heritage, Indian River County has an opportunity to
capitalize on ecotourism. From an economic development standpoint, the County, through its
County Environmental Lands Program, is actively preserving some of its greatest natural assets and
Community Development Department Indian River County 26
APPENDIX A
Comprehensive Plan Coastal Management Element
Indian River Lagoon, the St. Sebastian River, or other surface water bodies, the County's policy
should be to promote the connection of waterfront subdivisions to the sanitary sewer system. A
complete analysis of sanitary sewer is provided in the Sanitary Sewer Sub -Element.
• Stormwater Management
Since 1990, stormwater management facilities in the county have been designed to handle a 25
year/24 hour storm event, as well as to provide treatment before discharging stormwater runoff.
Because many sections of the county were developed prior to 1990, the level of service for
stormwater management facilities continues to vary throughout the county. Over the past several
years, the county has made progress in reducing flood hazards by constructing stormwater
management projects in certain areas of the county with known flooding problems, including Vero
Lake Estates, east Gifford and the Rockridge Subdivision. Moreover, projects such as the Sebastian
Stormwater Park and the North Relief Canal Pollution Control Facility, described previously in this
report, contribute to improved stormwater quality. Despite implementation of these projects, the
county needs to continue to identify, seek funding, and construct new stormwater improvement
projects in areas where needed. A more complete analysis of the County's stormwater management
facilities is contained in the Stormwater Management Sub -Element.
Sea Level Rise
Since the completion of the SLR vulnerability assessment in 2012 that was described in the Existing
Conditions section, Senate Bill 1094 was enacted, modifying Florida Statute section 163.3178(2)(fl
to require, amongother ther provisions, that local governments in Florida "include development and
redevelopment principles, strategies, and engineering solutions that reduce the flood risk in coastal
areas which results from high -tide events, storm surge, flash floods, stormwater runoff, and the
related impacts of sea -level rise within the coastal management elements of their comprehensive
plans. In accordance with this legislation, and based on the best available data from the.NOAA
Coastal Service Center sea level projection models and best available local projected inundation
data, County SLR inundation maps have been incorporated into this Coastal Management Element
for planning purposes (Figures 9.16, 9.17, and 9.18).

Inundation Risk by Land Use
The total land use area at risk from each SLR inundation scenario was analvzed. When evaluated
based on total acres inundated, the data indicate that under all three inundation scenarios theerg
impacts of SLR are on lands designated Conservation and Recreation. Notably, privately owned
estuarine wetlands and undeveloped lagoon island conservation areas appear to be the most
vulnerable to SLR inundation impacts. It is estimated that more than 85% of currently existing
coastal wetlands are at risk of inundation under the 3 foot sea level rise scenario.
Physical infrastructure such as roadways, power plants, ports and airports, landfills, hospitals and
schools were determined to be critical facilities that were initially evaluated in the 2013 Seven50
report. Based on the best available data from the NOAA Coastal Service Center sea level projection
models, risks to physical infrastructure at the one, two and three foot scenarios are described below.
• Indian River County has 4 airports east of 1-95. No impacts were reported.
• FPL has seven parcels under the category of Electrical Power Substation. The City of
Vero Beach has nine. No impacts were reported.
• FEC Railroad rights of way were assessed but did not show a vulnerability to sea
level rise (no miles of track impacted).
• The water and wastewater treatment plant analysis included the Indian River
Wastewater and Water Treatment facilities. Significant impacts may be encountered
at facilities located along the Indian River Lagoon which incorporate coastal
mosquito impoundments and estuarine marshes.
• Indian River County has 2 parcels under the data category of landfills. No impacts
were reported.
Community Development Department Indian River County 44
APPENDIX A
Comprehensive Plan Coastal Manaeement Element
• Hospital facilities are mainly concentrated in Vero. Beach. Under the 2 and 3 foot
scenarios approximately 6.8 and 16.5 acres of inundation, respectively, could be
possible on the Indian River Medical Center Parcell. Impacts were to undeveloped
portions of the parcel and no building infrastructure. would be affected.
_• The Indian River County Schools include five charter schools, eight public schools,
11 private schools and Indian River Communi y College. Fourteen total schools are
designated as storm shelters. None of these were impacted at any scenario.
• Evacuation Routes to and from the barrier islands were not shown to be vulnerable to
sea level rise at the three scenarios tested.
'Note: the currently undeveloped and unelevated east end of the overall IRMC parcel could be
impacted under the scenarios tested.
Mitigation and adaptation strategies
Based on the analysis provided in this element, the majority of the inundation impacts are projected
to occur within the Coastal High Hazard Area (CHHA); consequently, mitigation strategies that will
likely have the greatest effect on reducing exposure to inundation risk due to one foot, two foot and
three foot SLR scenarios involve reducing. the potential population and vulnerable development
within the CHHA. Therefore, the CHHA area should be used as an "Adaptation Action Area" (AAA)
to implement strategies that address sea level rise impacts. Strategies that accomplish these
objectives include reducing_ public infrastructure expenditures in at risk areas identified on the
inundation maps, preventing or capping the number of assisted.living facilities and similar special
needs populations and higher density developments within the CHHA/AAA, and acquiring
conservation and open space lands in the CHHA/AAA when feasible.
Future adaptation strategies may include relocation and/or elevation of critical infrastructure facilities
and roadways where appropriate, incorporation of living shorelines that provide coastal resilience
and carbon sequestration benefits, and improvements to stormwater conveyance systems that may be
susceptible to failure as a result of rising groundwater and tide. levels. Additionally, saltwater
intrusion will be a growing concern based on the cumulative effects of projected potential SLR
inundation and rising groundwater levels.

PLAN IMPLEMENTATION
An important part of any plan is its implementation. Implementation involves execution of the plan's
policies by taking actions and achieving results.
For the Coastal Management Element, implementation involves various activities. While some of
these actions will be ongoing, others are activities that will be taken by certain points in time. For
each policy in this element, Table 9.4 identifies the type of action required, the entity or entities
responsible for taking the action, the timing, and whether or not the policy necessitates a capital
expenditure.
To implement the Coastal Management Element, several types of action must be taken. These
include, but are not limited to: coordination with jurisdictional and reviewing agencies, establishing
marina facilities siting criteria, and protecting/preserving estuarine resources.
Overall plan implementation responsibility will rest with the Community Development Department.
Besides its responsibilities as identified in Table 9.4, the Community Development Department has
the additional responsibility of ensuring that other entities discharge their responsibilities. This will
entail notifying other applicable departments of capital expenditures to be included in their budgets,
