Mount Pleasant, South Carolina, is gearing up for a future with increased flood risks as climate change and rising sea levels continue to affect the region. On Monday, the town council reviewed studies that aim to identify areas most at risk for flooding by 2025 and to develop effective strategies for flood resilience. These steps are vital for the town’s preparation in dealing with flooding issues, ensuring both property protection and human safety.
Mount Pleasant’s Approach to Flood Resilience
Mount Pleasant has recognized the growing risk of flooding and is actively working on a flood resilience plan. The town is in the early stages of preparing a strategy to combat the rising tide-driven floods and storm surges, particularly as some areas are sinking. A team of researchers recently presented findings that will guide the town in understanding how these floods could impact residents in the coming years.
Mayor Will Haynie emphasized the seriousness of the issue, stating, “We’re taking this very seriously, we’re not being alarmist, but this is part of a logical and thoughtful way to protect property and protect human life.” The town is focused on creating a well-thought-out plan to address flooding before it becomes an even bigger issue.
Identifying Vulnerable Areas
As part of the study, researchers looked at two areas in Mount Pleasant that are particularly vulnerable to flooding: Haddrell Point, located near Shem Creek, and Daryl Creek, which is off the Wando River. These locations were selected because they feature both old and new infrastructure, which gives a clear picture of what areas might be more at risk due to outdated systems or development.
The study also focused on the land’s elevation to assess flood risks. The research found that 23% of Mount Pleasant is located at an elevation of level seven or below, which puts it in the “red zone” for flooding risks. Fortunately, Mount Pleasant’s elevation is higher than other nearby towns, such as Isle of Palms and Sullivan’s Island, meaning it may experience fewer flooding issues in the short term. However, the town still faces significant flooding challenges due to sea-level rise.
Financial and Safety Impacts of Flooding
The study also analyzed the financial impact of flooding over the next 25 years. For example, at Haddrell Point, researchers estimate that by 2050, extreme tidal flooding combined with heavy rainfall could result in an economic loss of $5.7 million. The same type of flooding at Daryl Creek could lead to a $5.1 million loss. Water Resources Project Manager Aaron Akin noted that neighborhoods with marsh-front homes, like those around Daryl Creek, are particularly vulnerable to financial losses from flooding.
The mayor stressed that while financial losses are significant, the safety of residents is the top priority. He pointed out that some parts of the town may become inaccessible during floods, which could hinder emergency services like firefighting or medical response. “There will be people in parts of town that cannot get to or leave their homes, which also has implications for firefighting or emergencies,” Haynie said.
Next Steps in Flood Preparedness
To further address the risk, Mount Pleasant has asked researchers to continue studying additional areas with high flooding risks. The town also plans to hold public hearings to raise awareness and involve residents in the process. This proactive approach ensures that the community stays informed and prepared for the flooding challenges ahead.
Mount Pleasant is taking significant steps to address the flood risks that could impact the town by 2025 and beyond. By identifying vulnerable areas, estimating financial losses, and considering the safety implications of flooding, the town is working on a detailed and effective flood resilience plan. As the situation evolves, the town will continue to collaborate with experts and residents to ensure a safer, more prepared community.
