Atlanta’s Most Notable Floods

Atlanta’s story of battling against the raging waters is a tale that goes back many decades. From the Chattahoochee River’s dramatic overflow to the havoc wreaked by Tropical Storm Alberto, the city has seen its fair share of flood events. The September 2009 floods, in particular, marked a catastrophic chapter in Atlanta’s history, triggered by several days of unrelenting rain that overwhelmed local watershed systems,. These floods were statistically rare, with a less than 0.01% chance of such high levels of rainfall happening in a given year.

Atlanta Historic Flood Events: No account of Atlanta’s flood history would be complete without mentioning the Chattahoochee River. This river, which gracefully weaves its way through the city, has, on occasion, overflowed its banks with devastating consequences. Next, we will examine in detail these significant flood events and their enduring influence on the Atlanta metropolitan area.

Chattahoochee River Overflow

The Chattahoochee River, a geographical feature that’s as much a part of the metro Atlanta area as its famous peach trees, has been a significant contributor to flooding in the North Georgia region. The river overflowed in 1919 and 1951, leading to considerable damage to Atlanta and surrounding areas. These events served as a stark reminder of nature’s might and the need for effective flood management strategies.

Notably, over the years, the Chattahoochee River’s floodplain has witnessed an upsurge in development. This trend has resulted in:

  • Higher flood risks
  • More severe flood events
  • Overflowing river banks contributing to soil erosion and sedimentation, affecting the health of local watersheds
  • Disrupted ecosystems and property damage in areas hit by the river’s rise, such as the Peachtree Creek

Tropical Storm Alberto

In the summer of 1994, Atlanta braced itself as tropical storms, like Tropical Storm Alberto, swept across the region. The storm led to federal disaster declarations for several counties due to its significant flooding impact. Alberto brought with it:

  • Up to 27 inches of rainfall in some areas
  • Extensive flooding throughout the impacted regions
  • Thousands of homes and businesses inundated
  • Major highways submerged
  • Access to many areas cut off

The storm’s wrath, originating from the Atlantic Ocean and passing through the Gulf of Mexico, brought heavy rains that caused major damage in rural areas and were felt far and wide.

The sight that greeted the aftermath of Tropical Storm Alberto was bleak. The repair costs for the damage caused by the storm added up to millions of dollars, underscoring the storm’s lasting financial impact. Yet, even in the face of such devastation, the resilience of the Atlanta community shone through as they worked together to rebuild and recover.

September 2009 Floods

Atlanta Historic Flood Events: The floods of September 2009 were unlike anything Atlanta had experienced before. The Chattahoochee River reached unprecedented levels, resulting in a 500-year flood event for the region. The tributaries of the Chattahoochee, such as Peachtree Creek and Nancy Creek, also saw record-breaking water levels, contributing significantly to the widespread flooding. The intensity of the flooding was evident at river gages, with waterways like Sweetwater Creek and the Dog River shattering previous records by reaching stages up to 20 feet above flood level.

The devastation of the September 2009 floods was far-reaching, impacting not only the Atlanta Metropolitan area but also extending to Northern Georgia. Ten lives were tragically lost, and widespread damage led to Federal Disaster Declarations across seventeen counties within Georgia, primarily in the Atlanta Metropolitan area. In fact, these areas received federal disaster declarations, emphasizing the severity of the situation. The impact of this event was a stark reminder of the power of nature and the importance of preparedness and effective response.

The Cost of Flooding

Flooding comes with a steep price tag. The 2009 floods in Atlanta resulted in substantial property damage, with initial estimates at $250 million that eventually reached $500 million, impacting over 20,000 homes and businesses. According to FEMA, flood damage in Georgia can amount to $25,000 per inch of water. More than 16,000 inquiries for federal aid were made as of September 2010, emphasizing the extent of recovery efforts needed after the Atlanta floods.

The costs associated with flooding are not limited to property damage alone. The impact on infrastructure, the economy, and the community’s wellbeing also need to be factored into the equation. We will now explore further the financial burden that flooding has imposed on Atlanta’s residential and commercial properties, as well as its infrastructure.

Residential and Commercial Losses

Atlanta Historic Flood Events: Residential areas bore the brunt of the 2009 floods in Atlanta, with a staggering 16,981 homes being impacted. Homeowners found themselves grappling with structural damage and mold growth due to flooding, with repair costs often surpassing $50,000. The aftermath of a flood is a daunting and distressing time for homeowners, with many faced with the monumental task of restoring their homes while dealing with the emotional toll of the disaster.

Commercial properties and other buildings were not spared either. Income-generating entities, including Airbnb guest homes, also suffered from the floods, resulting in a significant loss of revenue for the owners. The economic implications of these losses extend beyond the individual property owners, affecting the wider community and economy.

Infrastructure Damage

The infrastructure of a city is its backbone, and when floods hit, this backbone can be severely compromised. The Atlanta flooding led to major closures of interstates including I-20, I-75, and I-85, as well as extensive road blockages in Cherokee County, notably Interstate 575. Such disruptions have wide-ranging impacts, from the delay of emergency services to the day-to-day commute of the city’s residents.

Atlanta Historic Flood Events: The September 2009 floods, caused by continuous rain, also saw the inundation of the R.M. Clayton sewage treatment plant, leading to the release of millions of gallons of untreated sewage into the waters. This event underscores the extensive and often unseen damage that floods can inflict on a city’s infrastructure. It also highlights the importance of robust and resilient infrastructure in mitigating the effects of future flood events.

Flood insurance in Georgia covers essential building elements such as foundational walls, electrical systems, furnaces, built-in appliances, and can also cover personal property like furniture and electronics.

The cost of flood insurance varies, with the average annual cost for an NFIP flood insurance policy in Georgia being $803, while the average in Fulton County is $724. Rates can vary significantly, with premiums in some counties like Chattooga County reaching up to $5,985. Despite the cost, the peace of mind that comes with knowing you’re protected can be invaluable.
