Roofer in Sullivan's Island, SC

Sullivan’s Island’s stormwater drainage system, installed decades ago by the South Carolina Department of Transportation, is now struggling to keep pace with modern environmental challenges. Much of the infrastructure is clogged, deteriorating or simply not designed to handle the increasing volume of rainfall and high tides the island has experienced in recent years—issues expected to worsen with climate change and vertical land subsidence.

To address these concerns, the civil engineering firm SeamonWhiteside (SW+) was tasked with developing an island-wide stormwater master plan and infrastructure improvement strategy. Aaron Aiken of SW+ presented the firm’s findings to Town Council on Tuesday, Jan. 28.

The report revealed that much of the island’s drainage infrastructure is significantly undersized, with large portions rendered ineffective due to clogging. As part of their research, the firm gathered photos and feedback from residents, which they say provided invaluable data for validating their findings and could bolster future federal and state grant applications.

Currently, Sullivan’s Island has approximately 55,000 linear feet of stormwater pipes. If SW+’s recommendations are fully implemented, that figure will nearly double to 92,000 feet. The proposed improvements are designed to extend the functionality of the island’s stormwater system through 2074, ensuring effective flood mitigation for the next 50 years. SW+ estimates an annual maintenance cost of $4 million in today’s dollars.

The plan recommends 18 projects, categorized into two groups: high-priority improvements that require immediate action and future extensions to expand the system’s surface area over time.

“It’s no surprise to me as an engineer that Osceola Avenue ranks high on this priority list,” Aiken said. “Much of that is due to tidal intrusion, which comes over the roadway—and as time goes on, it’s only going to get worse.”

To address this, SW+ recommends raising Osceola Avenue by 18 inches at its lowest point and installing a new stormwater collection system that will channel water to a pump station at Station 10. The estimated cost for this segment is $9.8 million.

Other high-priority areas include Station 22 ½ and Station 26 ½, both of which require upgrades to larger pipes and the installation of a tidal backflow preventer, estimated at $1.8 million and $7 million, respectively.

South Carolina has no shortage of beautiful towns worth visiting, but this one is one of the state's best-kept secrets. Dolphins breach the crystal-clear waters as golf carts whisk past centuries-old live oaks. Picture a place where flip-flops meet fine dining, historic bunkers have been transformed into chic libraries, and every sunset feels like a private show.

This slice of paradise isn't just another beach town – it's where Southern charm and coastal luxury combine, creating an enclave that would make even California's elite raise their eyebrows in appreciation. These are just some of the awesome things a traveler can experience in South Carolina, and this exclusive island town offers all of them and more.

Sullivan's Island's beaches aren't just comparable to Florida's—some would contend they are better. While Florida may have more sunshine, Sullivan's Island is more secluded, allowing visitors to truly experience the coastline uniquely.

Visit Fort Moultrie, The Historic Fort That Saved America

This particular historical site is one of the many good reasons to visit South Carolina. Fort Moultrie is a testament to American resilience, where palmetto logs once absorbed British cannonballs like sponges.

Today, visitors walk the same grounds where Colonel William Moultrie's troops secured a pivotal victory in 1776, helping birth a nation. The fort, transformed over three centuries of coastal defense, offers an extraordinary glimpse into military history, with each chamber and cannon telling tales of courage under fire.

Summer offers the perfect setup for beach activities; the sun is ideal for a picnic on the beach or one of the island's meadows.

Sometimes, small towns leave a lasting mark bigger and better than the world's most sought-after destinations.

Greeted with “how ya doin‘?” instead of “keep it movin” where you feel like just another face in the crowd, the South is teeming with hidden gems and quaint getaways that will have you coming back again and again.

For example, when I visit Texas on occasion, I often find myself seeking out the small towns of Grapevine, Gruene, and Socorro, depending on where I am in the state, but certainly not Dallas or Austin.

Same goes for any state, but in this case, you may want to skip out on the tourist crowds of ever-so-trendy Charleston in favor of an idyllic, pint-sized island just 20 minutes away.

Practically a stone's throw from one of the South's most popular cities to indulge in rich history, epic eats, and timeless charm is Sullivan's Island, offering many of the same delights without hordes of visitors and overpriced menus.

This 3.5-mile-long barrier island is nestled along the Atlantic between numerous neighboring islands and, yes, Charleston.

Typically, you might hear of most vacationers making their way to Myrtle Beach, South Carolina's renowned coastal vacation spot lined with beachside resorts and a buzzing boardwalk, but Sullivan's Island has gotta be the state's best-kept secret.

Those seeking a tranquil beach getaway should look no further than Sullivan's Island, boasting a very walkable rustic downtown easy to peruse local shops, galleries, and bar-hop if you please.

While you may not see restaurants run by acclaimed chefs featured by the Food Network, among others, as you will in Charleston, you will discover homey southern comfort foods intermixed with “catch of the days” straight from the source.

Better yet, you won't have to spend a fraction of your paycheck on a cup of coffee since there's no Starbucks, a small example portraying the island's far less touristy vibes without the eyesores of chain restaurants ruining the townscape's character.

Originally named O'Sullivan Island after early settler Captain Florence O'Sullivan, the “O” has since been dropped, but many historic sites remain.

Having played a significant factor through multiple wars, including ground zero for the Battle of Sullivan's Island in 1776, tourists can visit preserved structures like Fort Moultrie, holding intriguing exhibits and sweeping views of the surrounding scenery.

Fort Moultrie also overlooks Fort Sumter, another significant site, but you'll need to detour back to Charleston to be able to reach the ladder via ferry.

While it may be tempting to grab a bite to eat in one of the country's most popular foodie cities, Sullivan's Island's food scene is nothing to sleep on, with exceptional seafood and mouthwatering barbecue that will have you asking for extra napkins.

Southern Living hyped up a few different spots, depending on your palate. If you're up to slurping down oysters, check out The Longboard's ‘Happy Hour'.

If you're the type to nibble every last bit of ribs, then Home Team BBQ is just for you. But, if it were me, I'd be feasting on a burger at Poe's Tavern, an establishment dedicated to famed poet Edgar Allan Poe, who was stationed on Sullivan's Island as a private in the Army in the 1800s.

Who woulda thunk it?

As delightful as Sullivan's Island's main strip and as fascinating and photo-worthy as the numerous historic sites may be, at its core, this island is a year-round beach destination.

Sullivan's Island Beach holds an impressive 4.7 Google Rating, largely in part due to so much open space, unlike, say, Myrtle Beach.

Station 18 Beach is also a tranquil spot, boasting white sand and calm waves, just like Sullivan's Island Beach.

One of the most underrated aspects, once you leave Charleston proper, is the ability to island-hop the region.

Next to Sullivan's Island, just past a small canal inlet, is Isle Palms Beach, well worth a day trip to see what it's all about with equally scenic beaches.

But where should you stay? You won't find name-brand hotels here. Sullivan's Island is all about cozy rentals.

Lining the shores from Sullivan's Island through next-door Isle of Palms are rows of beachside cottages.

You can book in a variety of ways, such as Airbnb, Booking.com, or by searching local agencies.

There's still plenty of occupancy to cap off winter with a relaxing getaway. I scoured the interwebs for the perfect seaside cottage, and this one is my favorite.

Costing only $410 for a weeklong stay, it's located directly next to the aforementioned Fort Moultrie and with immediate beach access and walkable to Sullivan's Island's Nature Trail.
