Historic Fourth Ward Park, Urban park in Old Fourth Ward, Atlanta, United States.

Historic Fourth Ward Park covers 17 acres (6.9 ha) in two separate sections of Atlanta's Old Fourth Ward. Its centrepiece is a 5-acre stormwater retention pond set in a bowl below the water table, crossed by a curved concrete walkway with metal railings and fitted with an aerator fountain. A bermudagrass amphitheater curves around part of the pond, and a curved stone retaining wall with steps rises above the water.

In the late 1980s and early 1990s Atlanta planned a $40 million stormwater tunnel; instead, engineer-economist Bill Eisenhauer proposed a green-infrastructure park around a 5-acre retention pond, costing $23 million. Architect Markham Smith helped organize stakeholders including the Trust for Public Land and the Atlanta BeltLine, which bought the declining industrial land beside the former Sears warehouse. Phase I opened in February 2011, the full grand opening followed in June 2011, and a northern extension opened in January 2012.

The pond's edge is partly ringed by an amphitheater cushioned with bermudagrass, so spectators sit on the grass slope itself. The park's name comes from the Old Fourth Ward, the neighbourhood where it was built around the stormwater pond.

The splash pad operates seasonally from May through October, while the playground is accessible year-round during daylight hours. Well-maintained walking paths connect different zones, making it easy to navigate throughout the grounds.

The lake serves a dual purpose as both a recreational feature and a stormwater management system that protects surrounding neighborhoods from flooding. This design demonstrates how parks can address practical infrastructure needs while providing community space.
