Outdoor Activity Center Stream Restoration (OAC)
Green Infrastructure Design Challenge
Project Overview
This project is located within a 26-acre urban nature preserve in southwest Atlanta. The Outdoor Activity Center (OAC) is property of the City of Atlanta located at 1442 Richland Road within the Oakland City neighborhood. The preserve and environmental education programs are managed by the West Atlanta Watershed Alliance (WAWA), a local 501c(3) non-profit organization.
The scope of this project is to introduce green infrastructure practices that include:
- Restoring above-ground stormwater flows by partially blocking inlets to the old, combined sewer pipe; and excavate a new channel between the northeast inflow area and the existing remnant channel to the southwest.
- Introducing a nature-based solution that will support gushing flows of surface water offset with pools that are reinforced with large boulders to emulate a cascading stream.
- Connecting the restored stream to a constructed floodplain at the northeast corner of the property. This will allow high stream flows and step pool runoff to be mitigated.
- Enhancing the trail system and providing access to environmental features of the OAC.
The technical objectives will be achieved using nature-based solutions including stream channel and flow restoration, a constructed wetland and a regenerative step pool conveyance.
