A City Bounded by a River and Crossed by Creeks
Sandy Springs covers about 38 square miles of north Fulton County, and the Chattahoochee River runs along its entire western edge, separating it from Cobb County. At the city's northern end, Morgan Falls Dam holds back Bull Sluice Lake. River levels here rise and fall with releases from Buford Dam upstream and Morgan Falls, as well as with rain across the watershed, so the National Park Service urges people to check conditions before heading to the water.
On the opposite side of town, Nancy Creek cuts through the far southeast corner on its way from Chamblee toward Buckhead. It collects runoff from paved areas in DeKalb County, including Perimeter Creek out of Dunwoody, and it is known for frequent flooding. Long Island Creek drains another part of the city. In a heavy storm, these small streams can climb far faster than the river does.
That mix is why water damage in Sandy Springs can mean very different things: a slow river rise in Riverside, a creek over its banks near the southeast border, or simply a failed water heater in a North Springs laundry room.
What Helene Showed Sandy Springs in 2024
When the remnants of Hurricane Helene moved through on September 26 and 27, 2024, the city received 8 to 11 inches of rain overnight. Nancy Creek, normally about knee-deep at Windsor Meadows Park, rose to roughly 20 feet, well past its 12-foot flood stage. The Chattahoochee flooded too, and at least 56 trees fell on city property, taking down power and communication lines.
There was also a lesson about planning ahead. Sandy Springs bought floodplain properties along Nancy Creek in 2012 and turned them into Windsor Meadows Park, which opened in 2018. During Helene, the park did its job and kept the worst of the flooding away from nearby homes.
Nancy Creek has a longer flood history as well. It set records during Hurricanes Ivan and Frances in September 2004, rose again with Hurricane Dennis in July 2005, and in September 2009 its floodwater damaged the Peachtree Dunwoody Road bridge. If your home sits near a creek, plan for flood cleanup before you need it.
Apartments, Mixed-Use Buildings and Perimeter Offices
Much of Sandy Springs has changed in recent years, with mixed-use apartment developments replacing older strip centers along Roswell Road. Perimeter Center adds a dense cluster of office towers. In stacked buildings, a single leak rarely stays put. Water from a toilet supply line or sprinkler head can run down through ceilings, light fixtures and walls into the units or suites below.
- Renters: Tell your property manager right away and photograph the damage to your own belongings for a renters policy claim.
- Condo and townhome owners: Check your HOA documents to see where the association's responsibility ends and yours begins.
- Office and retail managers: Wet carpet tiles, raised floors and server rooms all need attention fast to limit downtime.
Property managers and tenants alike can call (888) 817-5061 to be connected with local providers who handle multi-unit and commercial drying, from a single suite to several floors.
Steps to Take Before the Crew Gets There
- Shut off the source. Close the main valve, or the shutoff on the fixture or appliance that failed.
- Keep clear of electricity. Do not step into standing water near outlets, cords or appliances. Use the breaker only if you can reach it from a dry spot.
- Judge the water. A broken supply line is usually clean water (Category 1). Creek or river water that comes inside is Category 3 and can carry sewage and debris, so keep kids and pets away.
- Stay off flooded roads. Creek crossings can rise quickly during a downpour.
- Record the damage. Photograph each room, the source and damaged items before moving anything.
- Make the call. Phone (888) 817-5061 to be connected with a restoration company that can start emergency water removal.
From Extraction to Rebuild: How the Work Unfolds
Water removal
Pumps and extractors pull standing water out of carpet, pad and hard floors. On commercial jobs, crews often lift carpet tiles to reach the slab underneath.
Finding where water went
Moisture meters and thermal cameras trace water behind baseboards, inside cabinets and into adjoining rooms or units. Those readings guide the drying plan.
Drying the structure
Air movers and dehumidifiers run until readings show materials are dry. Saturated drywall and insulation are often cut away so wall cavities can dry. Learn more about structural drying.
Putting it back together
Final water damage repair covers drywall, paint, flooring and trim. For reconstruction, confirm the contractor's Georgia license on the Secretary of State's license verification site, and ask about insurance and training such as IICRC certification.
Fallen Trees, Roof Damage and Mold Prevention
Strong storms like Helene can bring trees down onto houses as well as power lines. A tree through the roof lets rain soak attic insulation, ceilings and walls, often more than shows at first. Storm damage cleanup should include drying the structure, not just tarping the opening. See storm damage cleanup for what that involves.
Following EPA guidance, mold can start to grow on damp materials within 24 to 48 hours, and Georgia summers speed it along. If you already see growth or smell mustiness, mold removal and containment may be needed.
Georgia does not appear to have a state license specifically for mold assessors or mold remediators, based on an industry roundup of state requirements. We have not found an official state statement confirming that, so ask any company for IICRC or similar certification and for moisture readings before and after the job. Our mold removal page explains how mold cleanup usually works.
Insurance, Flood Coverage and Staying Informed
- Flood is a separate policy. Standard homeowners and renters policies generally exclude flooding. Coverage comes from the NFIP or a private flood policy, and NFIP policies typically take 30 days to start.
- Check your flood zone. Look up your address on the FEMA Flood Map Service Center, especially if you live near Nancy Creek, Long Island Creek or the river.
- Keep a file. Save photos, receipts, moisture logs and the restoration company's drying report.
- Sign up for alerts. The city's opt-in Sandy Springs Alerts system covers severe weather and power outages, and City Hall answers a 24-hour line at 770-730-5600.
WaterQ cannot predict how an insurer will rule on a claim, but good records help. For cleanup help any time, call (888) 817-5061. Neighbors across the river can also find help on our Marietta page, and to the north on our Roswell page.

Sandy Springs Water Damage FAQ
Which creeks cause flooding in Sandy Springs?
Nancy Creek, which crosses the city's southeast corner, floods frequently and rose to about 20 feet at Windsor Meadows Park during Helene in 2024. Long Island Creek and the Chattahoochee River along the western edge can also flood in heavy rain.
Why does the Chattahoochee rise even when it is not raining in Sandy Springs?
River levels are controlled partly by releases from Buford Dam and Morgan Falls Dam, along with rain elsewhere in the watershed. The National Park Service recommends checking flow conditions before going near the river.
How do I get emergency alerts in Sandy Springs?
Sign up for Sandy Springs Alerts, the city's opt-in notification system for severe weather, power outages and other emergencies. City Hall also has a 24-hour line at 770-730-5600.
Does Georgia require mold remediation companies to hold a state license?
According to an industry roundup, Georgia does not have a state license specifically for mold remediators, though we have not found an official state statement confirming it. Ask for certifications such as IICRC and for written moisture readings.
Will WaterQ send a technician to my apartment or office?
No. WaterQ is a free referral service. We connect you with an independent local restoration company, and that company handles the inspection, drying and repairs. The line is available 24/7.
