Environmental Protection Agency Region 4 awarded the City of Roswell, Georgia $3,452,972 in a cooperative agreement (CFDA 66.202, Congressionally Mandated Projects) on June 1, 2026, to design and implement stormwater infrastructure construction and environmental restoration along the Chattahoochee River.

The project restores an intermittent stream feeding into the Chattahoochee River, including removal of 42 linear feet of 54-inch corrugated metal pipe culvert. A constructed wetland planted with native hydric plants will treat diverted stream flow before discharge. Bank stabilization of approximately 120 linear feet along the Chattahoochee River will use terraced stacked stone embankment and live staking. The project also constructs a children's stormwater garden between the stream and wetland, featuring interactive educational elements including water pumps, sand pits, and stream channels that emulate natural watershed hydrology. The constructed wetland receives and treats runoff from the educational garden alongside stream stormwater. The project restores natural conditions in the project area while providing public greenspace and educational access.

Period of performance runs through December 31, 2027. Place of performance is Roswell, Georgia. Total dollars obligated are $4,316,215. No sub-awards are included in this assistance agreement.

This action provides funding in the amount of $3,452,972 to the city of roswell, georgia to implement its project to restore the natural condition of the project area while also providing greenspace and educational areas for the public as directed in the 2023 consolidated appropriations act or as identified in an approved technical correction if one has been approved for this project. Activities:the activities to be performed include the execution and implementation of a storm water infrastructure construction project. Workplan activities consist of the restoration of an intermittent stream that feeds into the chattahoochee river, including removal of 42 linear feet of a 54-inch corrugated metal pipe (CMP) culvert. A portion of the intermittent stream will be diverted to a wetland that will be constructed on the east side of the project area. The constructed wetland will be planted with native hydric plants and includes an outlet control structure that will discharge back into the intermittent stream during large rain events. The remaining stream flow will be pre-treated with a series of constructed step pools before discharging into the chattahoochee river. Bank stabilization of approximately 120 linear feet is proposed along the chattahoochee river, downstream of the confluence with the intermittent stream, including a terraced stacked stone embankment and live staking where the stacked stone stabilization ties back into grade. The project also includes construction of a children's stormwater garden, between the intermittent stream and the constructed wetland, consisting of interactive educational elements that emulate the natural movement of water and sediment within a watershed. The educational environment will include water pumps, sand pits, and stream channels. The runoff is discharged into the constructed wetland where IT is treated alongside the stormwater runoff. Subrecipient:no subawards are included in this assistance agreement.outcomes:the anticipated deliverables include the restoration of the natural condition of roswell's ACE sand park property that has been negatively impacted by previous industrial uses, and the development of an interactive play area that incorporates the natural elements of the site and provides environmental education opportunities for visitors to the park. The expected outcomes include streambank restoration, protection and management due to impacts from erosion, the removal of invasive species inside the river corridor, the establishment of native plants throughout the project site, the management of off-site run-off through an improved streambank and BIO-retention system. The restoration of the park, stream, and riverbank, and the creation of recreation opportunities and access enhances the city's economic vitality. The intended beneficiaries include the residents of the city of roswell, georgia.
