Two developments this month changed what Upper Mount Pleasant knows about its future. In an update dated October 4, 2026, Smart Growth 41 and the Park West Master Association said they had filed a challenge in the South Carolina Administrative Law Court. It targets the state permit for the Highway 41 widening. On October 13, Mount Pleasant Town Council approved a settlement that caps the Republic Tract, 185 undeveloped acres on the Wando River, at 95 single-family homes. The town will buy most of the rest as a public park.
For anyone comparing Rivertowne, Dunes West or Park West, those two items point in different directions. The number of homes the corridor's largest open waterfront tract can hold is now set in a signed agreement, while the start date for the road widening is less certain than it was this summer.
Ninety-Five Homes Where the Ceiling Was 1,600
The Republic Tract sits on the Wando River behind the Rivertowne Country Club neighborhood, off Highway 41. Its zoning has been in dispute for years. The Town of Mount Pleasant's release lays out three possible outcomes for the same land.
| Scenario for the 185-acre tract | Housing allowed |
|---|---|
| Stays in unincorporated Charleston County with sewer service | Up to 16 units per acre, or up to 1,600 units |
| Annexed into Mount Pleasant under standard rules | Three units per acre, or more than 300 units |
| Settlement approved October 13, 2026 | No more than 95 single-family homes on about 56.25 acres |
Under the agreement, the town buys about 129 acres for $28.5 million. That land comes with more than two miles of Wando River waterfront and will be restricted to a passive public park through a deed restriction, a conservation easement or both. The town and the owner will split the cost of a public access road from Highway 41 serving both the park and the new homes. The purchase has a 90-day due diligence period, and closing could come as early as April 2027.
The 1,600 figure is the town's estimate of the most that county zoning would allow if the property got sewer service without joining the town. Closing the gap between that ceiling and 95 homes is what the town paid for.
Sewer Was the Lever, and It Set the Price
The dispute started in 2023, when the tract's former owners sued the town and Mount Pleasant Waterworks over rules that tied water and sewer access to annexation into the town, according to The Post and Courier.
Speaking to ABC News 4, Councilman Daniel Brownstein described the town's side simply. The developers wanted sewer so they could build in the county, and the town and Waterworks opposed it unless the property became part of Mount Pleasant.
Three prices for the same land track how much that uncertainty was worth.
- 2022: Mount Pleasant offered roughly $21 million for the entire 185 acres. The offer was rejected.
- Before the settlement: Highland Resources, a Houston-based developer, bought the tract in March for $37.5 million. It took the former owners' place in the lawsuit and dropped several claims for financial damages.
- October 2026: The town agreed to pay $28.5 million for about 129 of those acres.
The 2022 offer worked out to about $113,500 per acre. The settlement price works out to about $221,000 per acre for the park land. On paper, Highland's net cost for the 56.25 acres it keeps is about $9 million, roughly $95,000 per allowed home site before its share of the road. Each side paid for certainty. The town got a hard limit on homes, and the developer got a defined, buildable project.
"It absolutely is a win when you consider what could have been developed … if the tract had stayed in the county. We really had to negotiate away from that idea of the 1,600 (homes)."
Councilwoman Kathryn Whitaker made that comment to The Post and Courier on the night of the vote. In the same report, Brownstein said the deal "preserves a great deal of land in the northern part of town, two-thirds of the site." He told ABC News 4 that a larger development would have added traffic on Highway 41, where growth is already underway across the Wando near Clements Ferry Road.
That traffic point links the settlement to the second story.
The Road Meant to Carry Existing Growth Has a New Clock
Charleston County's Highway 41 plan is the "Road to Compromise" design that emerged in 2021. According to the county's project site, it widens the highway to four lanes from Clements Ferry Road to Dunes West Boulevard and Rivertowne Parkway. It stays at three lanes through the Phillips Community, then returns to four lanes to Highway 17. It also adds Laurel Hill Parkway, a new two-lane road between Highway 41 and Park West Boulevard. The Post and Courier puts the cost at $245 million. Because a State Infrastructure Bank grant helps pay for it, the project must be finished within four years, or by 2031.
The project already survived one close call this year. At a packed meeting on July 14, Town Council narrowly voted to keep its consent for the project. Councilwoman Alex Crosby cast the tiebreaking vote after the county had threatened to drop the project if consent were revoked.
After that vote, Devri Detoma, Charleston County's deputy director of Public Works, gave The Post and Courier the county's sequence to a groundbreaking:
- Advertise for contractor bids in September, open for about 45 days
- County Council picks a contractor, which takes about three weeks
- Construction starts about 90 days after that, which points to early 2027
The county's own project history page still lists construction for the fourth quarter of 2026. In the same Post and Courier report, the county said about 90 properties are affected by right-of-way acquisitions, and that no homes or businesses would be torn down or relocated under the current design.
The coalition's court challenge adds another step to that sequence. Smart Growth 41 and the Park West Master Association are asking the Administrative Law Court to review whether the South Carolina Department of Environmental Services properly weighed flooding, drainage, wetlands and water quality before approving the permit. In their update, the groups say the project still needs a separate U.S. Army Corps of Engineers permit. They also say the county cannot start construction that requires state approval while the permit is stayed. Those are the groups' statements, not a ruling. The coalition itself says it cannot predict when or how the case will end.
So a buyer in Upper Mount Pleasant today can say how many homes will someday be built on the Republic Tract, but cannot say when the Highway 41 widening will begin.
What September's Sales Say About a Corridor With a Supply Cap
The Charleston Trident Association of REALTORS reports this part of town as Upper Mount Pleasant, Area 41. Its September 2026 report, with data current as of October 9, shows single-family detached homes like this:
| Area 41 single-family detached | September 2025 | September 2026 |
|---|---|---|
| New listings | 89 | 73 |
| Closed sales | 59 | 63 |
| Median sales price | $965,000 | $995,000 |
| Days on market until sale | 49 | 55 |
| Percent of original list price received | 95.6% | 94.3% |
| Inventory of homes for sale | 186 | 151 |
Inventory fell 18.8 percent from a year earlier, and new listings fell 18 percent. Even so, homes took longer to sell, and sellers received a smaller share of their original asking price. The September median rose 3.1 percent, but the year-to-date median through September 2026 is $980,000, down 5.8 percent from $1,040,000 over the same months of 2025.
Even with fewer homes listed, Area 41 sellers received an average of 94.3 percent of their original list price in September 2026. The Republic Tract cap limits how much new supply can come years from now. It does not change how much room buyers have to negotiate on the homes for sale this fall.
Townhomes and condos in Area 41 are moving the other way on supply. In September 2026 their inventory was 59, up 25.5 percent from a year earlier, with a $560,000 median and 12 closed sales. For comparison, Lower Mount Pleasant, Area 42, had a September 2026 median of $1,375,000 for detached homes, up 14.6 percent, with inventory down 22.2 percent. That puts the Highway 41 side of town about $380,000 below Lower Mount Pleasant on the September median.
Where the November 3 Ballot Fits
How the town pays for the park is still open. According to ABC News 4, the town says it could use existing tax revenue. It also lists the Charleston County transportation sales tax as a possible source if voters approve it. That referendum is on the November 3, 2026 ballot. According to the county's referendum page, the program is projected to raise about $4.25 billion over 25 years, and $690 million of it, about 16 percent, is proposed for Greenbelt.
On the park itself, the town says details about planning and public access will come as the purchase moves forward. Brownstein told ABC News 4 that a boat landing, which some residents suggested online, would probably need dredging because of sediment. He said there are no current plans for one.
Questions Buyers Are Asking About the Corridor
Is the Republic Tract park open now? No. The town has to finish a 90-day due diligence period and other closing requirements, and closing could come as early as April 2027.
Who is building the 95 homes? Highland Resources keeps about 56.25 acres, which will be annexed into Mount Pleasant. Highland is also developing Magnolia Landing on the Ashley River. In a statement, Highland's CEO and president Clark Davis said the agreement provides "a clear path for the thoughtful and responsible development of the remaining land."
Does the Highway 41 plan run through Laurel Hill County Park? Yes. The new two-lane Laurel Hill Parkway would run through part of the park, connecting the roundabout at Park West and Dunes West Boulevards to Highway 41. The project as a whole would fill or clear about 12 acres of wetlands.
