Cobb CountyIssuing agency·Georgia·via the Georgia Procurement Registry (DOAS)The Chattahoochee River Trail was included in the 2018 Cobb County Greenways & Trails Master
Plan as a priority project and detailed in the Chattahoochee RiverLands Greenway Study, a regional river corridor plan for the 100-mile Chattahoochee River corridor. One task of this study was to develop a pilot project conceptual plan for a multi-use path on Cobb County-owned property between SR 139/Mableton Parkway and SR 8/US 278/Veterans Memorial Highway. The conceptual
plan was adopted by the Cobb County Board of Commissioners on June 23, 2020 and provides
unprecedented access to the portion of the Chattahoochee River south of I-285, giving people the opportunity to see, interact with, and experience nature in a new and unique way, while also
serving as a model for implementation of future RiverLand segments.
Phase II of the subject project proposes to provide paved paths for shared use by pedestrians and
bicycles along the Chattahoochee River between SR 139/Mableton Parkway and Nickajack Creek. In
addition, this phase includes a bridge over a small creek at the southern end of the project and
boardwalks over environmentally sensitive areas. The logical termini will be SR 139/Mableton
Parkway at Lee Industrial Boulevard on the southern end, where it will connect to an existing 10- foot wide shared-use path, and Nickajack Creek on the northern end. Nickajack Creek is also the
southern terminus for Phase I.

Project Justification Statement
The Chattahoochee River Trail was included in the 2018 Cobb County Greenways & Trails Master
Plan as a priority project and detailed in the Chattahoochee RiverLands Greenway Study, a regional
river corridor plan for the 100-mile Chattahoochee River corridor. One task of this study was to
develop a pilot project conceptual plan for a multi-use path on Cobb County-owned property
between SR 139/Mableton Parkway and SR 8/US 278/Veterans Memorial Highway. The conceptual
plan was adopted by the Cobb County Board of Commissioners on June 23, 2020 and provides
unprecedented access to the portion of the Chattahoochee River south of I-285, giving people the
opportunity to see, interact with, and experience nature in a new and unique way, while also
serving as a model for implementation of future RiverLand segments.
Phase II proposes paved 10'-17' shared-use paths with intermittent modal separation for pedestrians and bicycles along the Chattahoochee River between SR 139/Mableton Parkway and Nickajack Creek, beginning at the southeastern quadrant of SR 139/Mableton Pkwy and Lee Industrial Blvd and continuing under the SR 139 bridge to Nickajack Creek. The work includes a bridge over an unnamed creek at the southern end and boardwalks over wetlands and other environmentally sensitive areas, connecting at the south to an existing 10-foot wide shared-use path and at the north to Nickajack Creek and Phase I, following the Chattahoochee Riverlands Design Guide. Delivery is Design-Build combining design and construction in one contract, including schedule management, permits, environmental re-evaluation, utility coordination and completion within the RFP timeline.
