The Cobb County Board of Commissioners has unanimously approved the park naming of approximately 103 acres of County property on Discovery Boulevard in Mableton as "Discovery Park at the River Line."

The property includes more than one mile of river frontage and a variety of well-preserved Civil War-era earthworks. A portion of the property has been listed on the National Register of Historic Places and has deed restrictions which allow only its use as a historic park with passive recreation and interpretation.

Cobb County has long owned the site and set aside roughly $1 million of special purpose local option sales tax (SPLOST) money to convert it into a passive park. In the early 1990's, Cobb County acquired approximately 103 acres of land along the Chattahoochee River on what is now Discovery Boulevard. In 2018, the master plan for the park was approved by the Board of Commissioners but a park name was undetermined. Since that time, multiple groups have continued to work on a suitable name for the park.

“The name reflects the unity and history of the park,” said District 4 Commissioner Lisa Cupid, who represents the area where the park is situated in Mableton. “The term ‘discovery’ ushers in people to discover the various aspects of this feature of our community.”

Southeast Cobb County was the scene of some of the Civil War’s most dramatic action over 150 years ago. More than 100,000 soldiers serving under Confederate General Joe Johnston and Union General William T. Sherman marched through the area and set up massive fortifications during the historic Atlanta campaign, ultimately setting the stage for Sherman’s March to the Sea.
