Higher Waters: Suncoast Quality of Life
Strengthening the Impact
Why did The Patterson Foundation support this initiative?
The Patterson Foundation strengthens the efforts of people, organizations, and communities by focusing on issues that address common aspirations and foster wide participation. Rising water levels have the potential to significantly impact not only our world but also our local communities.
How did The Patterson Foundation invest in this initiative?
As it learned from their research and experience, The Patterson Foundation shared its findings in various ways, including the creation of a repository of science-based, easily accessible data on rising water levels in Charlotte, DeSoto, Manatee, and Sarasota counties. This resource library includes charts, maps, and other resources that clearly and thoroughly illustrate the current and projected impact of higher waters on our shores.
Why did Higher Waters: Suncoast Quality of Life evolve into Community Preparedness, Recovery, and Resiliency?
Within each of The Patterson Foundation’s diverse initiatives, one will find a consistent thread of efforts working toward outcomes that strengthen opportunities for people to thrive.
The Patterson Foundation created its Higher Waters initiative to explore and understand how the rising levels of our gulf, bays, rivers, and inland waters could significantly alter our coastlines and landscapes — and, therefore, our quality of life.
In September 2022, Hurricane Ian landed in Florida, Georgia, and South Carolina, leaving much destruction and damage behind and impacting millions of people directly and indirectly.
Hurricane Ian’s impact reaffirmed our work in this space but also served as an important reminder of how natural disasters beyond rising water levels affect our Suncoast region. Near Hurricane Ian’s one-year anniversary, TPF evolved its Higher Waters: Suncoast Quality of Life initiative to Community Preparedness, Recovery, and Resiliency to reflect a transition of focus to exploring how our community navigates disaster preparedness, recovery, and resiliency.
Capitalizing on ongoing efforts and conversations to learn from Hurricane Ian to mitigate, adapt to, and recover from disasters, this initiative will connect and collaborate with our communities to strengthen three distinct disaster focus areas: Preparedness, Recovery, and Resiliency.
Are our water levels rising?
In the waters near Charlotte, DeSoto, Manatee, and Sarasota counties, satellite-based measurements have shown a steady increase in local sea level since 1950 — about 1.2 inches (30.5 millimeters) every ten years. Rising seas can produce coastal flooding that impacts other bodies of water located inland.
How much are water levels expected to rise in the Sarasota Bay area by 2050?
In other words, the Estuary Program's scientists expect 8 to 9 more inches of sea-level rise by 2050, on top of the approximately 6 inches of rise recorded between 2000 and 2020.
Why are our waters rising?
- Climate: Rising air and water temperatures are melting glaciers and ice sheets, thus increasing water levels.
- High Tides & King Tides: Tides are caused by the moon’s gravitational pull, causing it to pull the waters towards it onshore. The stronger the gravitational force, the stronger the tide. During high tides, water from the sea comes onshore and floods nearby low-lying areas, causing “nuisance flooding.” Similarly, when tides are higher than usual, they are called king tides (also known as sunny day floods) and can cause flooding too.
- Rain: Rain intensity has increased as global and local air temperatures have risen.
- Excessive Heat: Excessive heat can increase extreme rainfall.
- Storm Surges: Hurricanes and other strong storms can force water to surge over land, causing floods and often significant damage to infrastructure and buildings. Storm-related surges will come on top of rising water levels, compounding the potential for severe damage.
Do higher waters only impact those who live near the coast?
How do higher waters impact our community?
Arts, Culture, & Recreation
- Historical and cultural resources are not only a legacy of the past but significant sources of our tourist economy. These sites can be vulnerable to flooding and higher waters.
- Sea-level rise also affects our beaches since it causes coastal erosion and requires beaches to be renourished with sand.
- Public and open spaces for recreation are essential to help communities thrive. Flooding impacts our ability to do so in our parks and other areas.
- Service, retail/trade, finance, and real estate industries are likely to be impacted by higher waters, affecting the economic health of our counties, region, and state. Businesses, such as those closer to the coast, experience a loss in revenue if they have to temporarily or permanently close due to flooding. Their employees experience a loss in wages if they cannot get to work because of flooded roads.
- Flood Insurance rates are increasing in response to the growing risks of frequent flooding and storm surge.
- Higher waters lead to general changes in the chemistry and pH of bodies of water. These changes impact the entire ecosystem, starting with the smallest prey and moving up the food chain to large predators. Their numbers decrease as it becomes more challenging for prey to find food for survival. As available prey decreases, predators are more likely to compete for food and either change locations if possible or risk dying out.
- Seagrasses are essential plants found in coastal waters. They provide significant functions for coastal ecosystems, such as offering food, habitat, and nursery areas for many marine species. In our region, they provide food for manatees and housing for young fish. A positive feedback system involving adequate sunlight and seagrasses allows the plant to filter our waters. The more sunlight that penetrates the water and reaches the seagrass, the deeper it expands to further filter the water. However, seagrasses dieback when various pollutants and contaminants reduce water clarity and promote algae growth which reduces the amount of light reaching the seagrasses. The Indian River Lagoon is an extreme example of this.
- Sea-level rise impacts animals such as dolphins. Dolphins often move to shallow waters to escape noises and personal watercraft that cause injury. As waters rise, the availability of those shallow water environments decreases. When pollutants such as PCB and legacy contaminants increasingly accumulate in the water from the dry land, scientists observed that it shortens the lifespans of male dolphins and kills firstborn calves.
- Damages caused by storm surges and flooding can cause accidents and injury to residents (including the risk of drowning), limit access to healthcare services, and increase mold exposure.
- Stormwater can cause flood damage and impact the quality of the water we use to eat and drink. For example, sewage can contaminate our drinking water supply.
- When essential services experience damage to their infrastructures, such as healthcare facilities, shelters, emergency responses, and more, it disrupts their ability to respond to their residents' needs. Essential services also include human service providers that provide shelter, clothes, and food to their clients.
- Flooded roads, bridges, pathways, and damaged vehicles such as trains, buses, and cars impact people’s ability to get to work and school, access virtual services, or evacuate in emergencies.
- Floods can damage the structure of homes and appliances while encouraging the growth of mold and mildew.
- Individuals living near the coast or along the waterfront experience the immediate impacts of higher waters. However, those in vulnerable and low-lying areas experience flooding, too, due to rainfall and storm surges.

What are the economic benefits of addressing higher waters?
In Florida, ocean and coastal resources contribute around $18 billion annually to the economy and support over 228,000 jobs. As Florida’s number one industry, tourism attracts visitors to the state and the Suncoast region for water-based recreation and activities. Higher waters impact our waters and the people and wildlife that depend on them. Preventing potential losses and investing in the future saves money long term.

What legislation addresses rising water levels in Florida?
The Resilient Florida Program has available grants for counties, municipalities, water management districts, and more to address the impacts of flooding and sea-level rise. Eligible applicants can receive funding to plan for vulnerabilities by conducting vulnerability assessments and implementing projects for adaptation and mitigation. Funding for grants is scheduled to continue between 2022 and 2024. View grants awarded for the fiscal year 2021–2022 here.
By mandating cities and countries to conduct vulnerability assessments in the same manner and using the same data, the state plans to create a state assessment and plan.
Additionally, The Resilience Act established the Florida Flood Hub for Applied Research and Innovation for researchers to further study the effects of sea-level rise and other environmental issues.
