The South End of Isle of Palms Gets Its Sand Last, in the Season Least Likely to Cooperate

The north end of Isle of Palms got its new beach in high summer. Marinex finished Reach 1, the stretch from Mariner's Walk to Dewees Inlet, in 35 days, more than two weeks ahead of schedule, Live 5 reported in early September. The Post and Courier reported that crews paused that phase for equipment repairs and still finished in about 35 days.

The south end, from the Isle of Palms Pier to Breach Inlet, comes last. It is the only phase the City is paying for entirely on its own. Its tentative start date is November 1, which puts its pumping in the same fall weather that has already kept the dredge tied up in Charleston Harbor for days at a time this October.

Where Reach 3 Runs

The City's construction plan, dated July 17, 2026, shows Reach 3 as an 8,600-foot segment receiving 800,000 cubic yards of sand. Its map labels beach accesses 2 through 9 and marks both the Pier and Breach Inlet. The same plan shows a construction access at 25th Avenue.

Compared with the rest of the project, Reach 3 is not a small finishing touch:

All told, the project adds about 2.5 million cubic yards to the island's shoreline. The sand comes from an offshore borrow site about two miles southeast of the Pier. Every cubic yard placed on the south end therefore depends on a dredge working in open water.

A Schedule With No Slack Left in It

The City's posted schedule had Reach 2 pumping from September 1 for about 45 days. On paper, that wraps up in mid-October. By the City's October 8 update, the dredge was sheltering in Charleston Harbor. The City wrote that this season's nor'easters had been "particularly persistent, taking longer than usual to clear." Reach 2 was more than 90% complete, with about 75,000 cubic yards still to place, and the forecast finish had moved to October 21, weather permitting.

Four days later, the October 12 update said the dredge was still "down and staged in Charleston Harbor," with Marinex watching the sea state for a chance to return to digging.

The arithmetic for the south end is tight. The City lists Reach 3 as starting a tentative November 1 and lasting 45 days, with demobilization on December 15. Forty-five days from November 1 lands right on that demobilization date. Any delay in finishing Reach 2, or any stretch of rough water in November, pushes south-end work closer to the holidays. Neither the City nor the contractor has published a revised Reach 3 date. The City's project page and its construction forecast map are the places to check before planning a beach morning around it.

The summer phase had calmer seas and finished early. The south end gets the season that has already cost Reach 2 its original finish date.

What a Single Block of Beach Goes Through

The full phase may take six weeks or longer, but no single block of the south end will be a work zone for that long. The City describes the work as moving down the shoreline in sections:

1. A fenced work area of roughly 300 yards at a time. In most cases, pedestrians can walk around it.
2. Short restrictions during dune construction, when getting around the work zone may be briefly blocked.
3. Sand ramps built over the dredge pipeline so beachgoers can cross it to reach the water.
4. Heavy equipment running around the clock, moving forward 100 to 300 feet a day.

The City's project FAQ addresses nighttime work this way.

"Residents may notice some light and backup alert sounds during nighttime hours. Work is expected to progress at a rate of 100–300 feet per day, so any disturbances in your area should pass within a night or two."

Those two figures work out to a pace. Covering 8,600 feet in the scheduled 45 days averages a little under 200 feet a day, in the middle of the City's stated range. A weather pause stops that progress entirely, which is why the start date matters more than the pace once the dredge is running.

The calendar adds two seasonal changes. Paid enforcement in the City's municipal beach lots and at the Front Beach on-street stations runs March 1 through October 31. That makes the tentative Reach 3 start the first day after paid parking ends. October 31 is also the Halloween Golf Cart Parade and Carnival, from 4 to 6 p.m., with parade line-up at 3:30 p.m. on 27th Avenue and golf carts required to be registered.

For dog owners, the fall and winter off-leash window on the beach runs from 4 p.m. to 10 a.m., September 15 through March 31. With equipment working around the clock, those early-morning and late-afternoon hours will overlap with active work wherever the fence happens to be that week.

Why the South End Is the City's Alone

The funding split explains why this phase carries a different weight at City Hall. On the north end, Reaches 1 and 2, the City pays 47% and the Wild Dunes Community Association pays 53%. The City says that split was set using reported gross income from short-term rental and business licenses for the 2025 license year. On the south end, the City covers the whole cost of Reach 3. Across all three reaches, the City carries 64% of the project and the association 36%.

State money is aimed at that south-end bill. The City has received $1.5 million of the $5.3 million in state funding it requested, and says those funds will offset the cost of Reach 3. So the stretch from the Pier to Breach Inlet is both the last phase scheduled and the one paid for out of public money, with roughly $3.8 million of the state request not yet in hand.

The Conversation That Starts When the Pumping Stops

Reach 3 finishes the 2026 project, but the City is already looking at how long this sand will last. Isle of Palms City Council hired Foth/Olsen to study the City's beach restoration strategy. The City says the goal is to find ways to extend the life of future sand placements and reduce how often large-scale restorations are needed. The City also notes that any recommended alternatives would need to be put in place within a few years of the 2026 project to get the most out of the newly placed sand.

That work is already on public agendas. The Beach Preservation Committee's October 1, 2026 agenda listed a discussion of the alternatives-analysis presentation. It also listed a separate recommendation on feasibility and design work for a future terminal groin and shoal management. If the south end gets its sand by mid-December, those committee discussions will shape how long it lasts.

Until then, the most useful dates are the ones the City posts on the renourishment project page: when Reach 2 is declared complete, and when the first pumping day between the Pier and Breach Inlet is confirmed.

A changing shoreline raises questions for people who own on the island and for people considering a move there, about timing, about what the beach will look like next season, and about how long-term planning like the Foth/Olsen study fits into a bigger decision.
