Addendum to Ph. I Arch Survey of the Kennesaw Mountain to the Chattahoochee River Trail

The proposed project would construct a 10-foot (desirable) to 8-foot (minimum) multi-use concrete path along the project corridor, as described below. The path would be separated from the roadway by a 5-foot buffer, consisting of curb and gutter and a minimum 2.5-foot grassed buffer strip, at all locations.

At its southern terminus, the proposed multi-use trail would begin on West Atlanta Road, just south of South Cobb Drive (SR 280), where it would tie into a proposed Cobb County DOT multi-use trail project to the south. The proposed multi-use trail would continue north along the east side of West Atlanta Street to East Dixie Avenue. West Atlanta Street would be narrowed and re-striped for 11-foot lanes in this area to avoid impacts to the railroad and existing roadway bridge over South Cobb Drive/SR 280. At East Dixie Avenue, the proposed multi-use trail would tie into a project by others (STP-OOOE[160], PI No. 771232), which proposes on-street bike lanes along West Atlanta Road from East Dixie Avenue north to Brown Park. The proposed multi-use trail would continue north from this location along the east side of Brown Park, over South Marietta Parkway via a proposed new pedestrian bridge constructed as part of this project, and along  the west side of the railroad tracks to the crossing at Waverly Way. At this point, the proposed multi-use trail would cross the railroad tracks at an existing crossing, and would continue north along the east side of the railroad tracks within existing railroad right-of-way (ROW) to Whitlock Avenue. An 8-foot trail would be required between Waverly Way and Whitlock Avenue to avoid impacts to existing structures.

At Whitlock Avenue, the proposed multi-use trail would tie into the existing Marietta Station Walk, which extends along the railroad tracks from Whitlock A venue north to Polk Street. While minor drainage improvements would be made to the existing Marietta Station Walk, no trail construction or reconstruction would occur in this area. The proposed trail construction would resume at Polk Street, where the multi-use trail would continue north along the west side of the railroad tracks to Kennesaw A venue. At Kennesaw Avenue, the proposed trail would cross the railroad tracks at an existing track crossing, and would continue on both sides of Kennesaw A venue between the railroad tracks and Church Street. This would allow trail users to utilize the existing crosswalk at the Kennesaw Avenue/Church Street intersection. On the north side of Kennesaw Avenue, the trail would tie into an existing pedestrian bridge over North Marietta Parkway/SR 120 Loop. The proposed multi-use trail would resume on the north side of North Marietta Parkway, following the west side of the Brumby Loft property in order to minimize impacts to adjacent historic homes. Also in this area, an impact to an existing parking lot on the Brumby Loft property would be reconstructed on-site.

The proposed multi-use trail would continue north along the west-southwest side of Brumby Street, which is a one-way street. Brumby Street would be reduced from a variable 14- to 18-foot lane to a consistent 14-foot lane to minimize impacts to adjacent properties. The proposed path would then continue north along the west side of Campbell Hill Street. At the intersection of Campbell Hill Street and North Sessions Street, the path would cross North Sessions Street to continue along the north side of North Sessions Street until its intersection with St. Joseph's Way, where it would cross to continue along the south side of North Sessions Street to Roselane Street. The proposed trail would continue north along the west side of Roselane Street to Radium Street, where it would cross to the east side of the roadway. It would then continue north along the east side of Roselane Street until the proposed northern terminus at Tower Road. At this terminus, the proposed multi-use trail would tie into an existing path at the intersection of Tower Road and Roselane Street.

The total project length is approximately 2.3 miles. The existing ROW through the project route varies from 30 to 100 feet. This degree of variation occurs due to portions of the project being constructed along both two-lane streets and one-way streets. The amount of additional required ROW would vary from 0 to 10 feet.
