Rottenwood Creek Trail is part of a larger effort by the City of Marietta and its partners to expand the current trail network by developing a connection piece between the Mountain to River Trail and the Bob Callan Trail. This trail will create an east-west connection between Kennesaw Mountain and the Chattahoochee River.
The project is currently divided into two phases. Phase I begins at Alumni Drive on the Kennesaw State University-Marietta campus and travels east to Franklin Gateway at the Franklin Gateway Sports Complex. This portion is currently within the right-of-way and acquisition phase, with construction estimated to begin in 2022. Phase II begins on Franklin Gateway and travels south and east across I-75, terminating at the intersection of Delk and Bentley Roads, and ultimately tying into the Bob Callan trailhead at Terrell Mill Road. A concept report has been approved by GDOT for this phase. The next step for Phase II is engineering and design.
Heath and Lineback Engineers, Inc. is applying for a Conditional Letter of Map Revision (CLOMR) from the Federal Emergency Management Agency (DHS-FEMA) on behalf of the City of Marietta to revise FIRM panels 13067C0109H, 13067C0117G and 13067C0136G, as a result of building the multi-use trail along Rottenwood Creek. Due to the five pedestrian bridges proposed to cross the creek, the project will result in increases in the 1% annual chance (base) water-surface elevations for a portion of Rottenwood Creek. Maps depicting these proposed changes can be found above.
