Hardeeville has two centers. The older one is historic downtown, on the side of the city closer to the Savannah River and the Savannah National Wildlife Refuge. The newer one, the New River area along U.S. 278, is filling with planned communities such as Hilton Head Lakes, Hearthstone Lakes, part of Sun City Hilton Head and Latitude Margaritaville. Between 2000 and 2020 the population climbed from about 1,800 to 7,473, and the city now covers nearly 57 square miles across Jasper County and a corner of Beaufort County. That mix of brand-new houses and older homes shapes the kinds of water damage people here run into.

River Lowlands, Refuge Marsh and Savannah-Area Tides
Wikipedia gives the city's elevation as roughly 20 feet, but the land drops toward the Savannah River and the refuge wetlands along the city's western edge. The Fort Pulaski tide gauge near the mouth of the Savannah is the reference point for this whole area. It reached its record 12.56 feet above mean lower low water during Hurricane Matthew in October 2016 and 12.24 feet in Tropical Storm Irma on September 11, 2017. In Matthew, the National Weather Service also noted that some of the deepest inundation in the region occurred inland, away from the beaches.
For many Hardeeville homes the more frequent threats are heavy rain, wind and tree damage rather than surge. Before you buy or rebuild, look up the property on FEMA's flood maps, and remember that flood coverage is a separate policy.
New Construction Along U.S. 278: Ponds, Slabs and Supply Lines
Planned communities in the New River area are built around stormwater ponds, and most houses are recent construction. Water problems there tend to look like this:
- A pond or swale that backs up in a long downpour, pushing water toward garages and slab edges.
- New plumbing connections, ice-maker lines and water heaters that fail during the first years.
- AC condensate drains clogging and dripping through ceilings during the cooling season.
- Gutter downspouts dumping right at the foundation on sandy lots.
Builder warranties and HOA rules may matter here. Check whether the issue falls under a warranty, and tell the HOA if a common-area pond or pipe is involved. For the inside of the house, start water extraction and drying promptly; slab floors under laminate or carpet can hold water for a long time.

Older Houses in Historic Hardeeville
Homes in the older part of the city and on surrounding rural roads come in every form, and if yours sits on a crawl space or is a manufactured home, the space underneath deserves attention. Crawl spaces and the underside of manufactured homes collect water from plumbing leaks and poor grading, and the damage often stays out of sight until floors go soft. After a heavy storm, take a look under the house with a flashlight, and check that skirting, vapor barriers and ductwork are not sitting in water. A restoration crew can remove wet insulation and dry the space before joists or subfloors start to decay.
Mold Risk in the Hot, Humid Savannah River Basin
Summer heat and humidity in the southern Lowcountry give mold every advantage. If drywall, carpet or cabinets stay wet more than a day or two, growth is likely, especially in a house without power after a storm. Start drying immediately with AC or dehumidifiers, remove soaked pad and baseboards, and have moisture readings taken in the walls. Visible growth larger than a small patch, or mold inside the HVAC system, warrants professional mold remediation with containment.

Who to Call in Hardeeville and Jasper County
The City of Hardeeville's hurricane preparedness page links to the state's Know Your Zone evacuation map, evacuation routes and power outage reporting for the local utilities, and the city uses an Everbridge system for emergency notices. Jasper County Emergency Management is based in Ridgeland and coordinates countywide response.

Frequently Asked Questions
My new home is under builder warranty. Should I still call a restoration provider?
Yes, if water is actively spreading. Stop the source, document it, and notify the builder in writing, but do not let wet drywall and flooring sit while you wait for a warranty visit. Emergency extraction and drying limit the damage, and most warranties and insurers expect owners to take reasonable steps to prevent further loss. Keep receipts and photos.
Is Hardeeville at risk from Savannah River flooding?
Areas closest to the river and the Savannah National Wildlife Refuge are low, and storm tides along the lower Savannah have set records in recent storms, including Matthew in 2016. Away from the river, rain, wind and drainage problems are more common causes of damage than rising river water. Check your parcel on FEMA's flood maps for its specific zone.
Which county handles my permits and drainage?
Most of Hardeeville is in Jasper County, but part of the city extends into Beaufort County. Inside city limits, start with the City of Hardeeville for building permits. For issues outside the city, or if you are unsure, check your property record to confirm the county before calling, since the two counties run separate offices.
