Mount Pleasant Faces Millions in Potential Flood Damages by 2050, New Study Warns

MOUNT PLEASANT, SC — Town officials in Mount Pleasant are evaluating sobering new research that forecasts multi-million dollar flood damages by 2050 if major storm surges and sea-level rise trends continue.

At a Monday town council meeting, researchers presented a detailed study examining low-lying flood-prone areas and how infrastructure could be impacted over the next 25 years. The findings emphasize the need for proactive planning to safeguard property, road access, and emergency services.

Key neighborhoods at risk: Haddrell Point and Darrell Creek

According to the study, two major zones — Haddrell Point, near Shem Creek, and Darrell Creek, off the Wando River — are especially vulnerable to tide-driven flooding and storm surge scenarios.

“These locations show both the legacy of older infrastructure and the vulnerabilities of newer development,” said Ryne Phillips, a senior civil engineering team leader.

Researchers noted that 23% of Mount Pleasant sits below elevation level seven, placing large portions of the town within the flood “red zone.” While some surrounding municipalities like downtown Charleston face more immediate threats, officials stressed that Mount Pleasant requires its own targeted flood resilience strategy.

Projected economic losses and infrastructure strain

If current climate trends persist, Mount Pleasant could face serious financial consequences. Simulations revealed that by 2050, an “extreme tide plus 10-year rainfall” event could result in:

• $5.7 million in economic losses at Haddrell Point

• $5.1 million in projected damages in Darrell Creek

These estimates come from Live5News, which covered the town council’s discussions.

Aaron Akin, a water resources project manager, warned that marshfront neighborhoods are particularly at risk for flooding-related economic hardship.

Mayor Will Haynie echoed the concern, saying, “There will be people in parts of town that cannot get to or leave their homes, which also has implications for firefighting or emergencies.”

What’s next for flood resilience in Mount Pleasant?

The town has tasked researchers with further evaluating other vulnerable areas and holding public hearings to engage residents. Town leaders say the priority is not just about protecting property, but ensuring human safety during future climate events.

“We’re taking this very seriously,” Haynie said. “This is part of a logical and thoughtful way to protect property and protect human life.”
