State Route 6 Corridor Study Final Report - Cobb County Government

Two alternate scenarios were developed to compare against the baseline, a trends
scenario and a corridor assets scenario. The trends scenario assumed that current
growth, development, and personal travel trends will continue through 2030. This
means the predominant mode of transportation in 2030 will still be the single occupant
vehicle (SOV). The transportation focus was to manage the forecasted increase in
commuter traffic and provide congestion mitigation for the critical locations within the
corridor. The trends scenario evaluated whether Segments 1, 3, and 4 should be
widened to six lanes, and Segment 2 should be widened to eight general purpose lanes
or seven lanes, which included a reversible high occupant vehicle (HOV) lane.
The corridor assets scenario focused on the natural and built resources within the
corridor. The purpose of transportation projects in this scenario were to support or
enhance the assets with public preservation or investment. The corridor assets scenario
focused on providing a parallel travel corridor to SR 6 and widening the section of
SR 6/Camp Creek Parkway for capacity addition as well as initiating new local bus
service. The corridor assets projects were carried forward to the recommendations.
2.5.2 Land Use
Three land use concepts were developed to accompany the transportation scenarios: a
regional growth framework, a local growth framework, and a sustainable growth
framework. The regional growth framework was based on the ARC Envision6 Regional
Development Policy for metropolitan Atlanta, which provides a vision to unify the
Atlanta Region. The plan views the region from a macro scale and combines areas with
similar land uses. It does not allocate land uses at the parcel level, but it does form a
strong foundation for planning initiatives at the local level. It helps tie together the
plans of various governments and municipalities and provides a single direction for
growth of the region.
The local growth framework was based on existing future land use policies for the
various jurisdictions in the SR 6 corridor study area. This framework reflected the local
desires of each jurisdiction and indicates preferred land uses at a parcel‐specific level of
detail. Though the Envision6 Regional Development Policy for Atlanta was used as a basis
for future development plans, the existing jurisdictional boundaries are defining edges
for different kinds of developments.
The sustainable growth framework combined both the regional and local land use
plans, while adding components that specifically address the three sustainability
