$1.15 billion in public infrastructure is headed to a referendum — and Cobb County's development corridor is first in line to benefit.

Cobb County and seven partner cities have advanced a Special Purpose Local Option Sales Tax capital projects plan totaling $1.15 billion.

A public referendum is expected later this year. If it passes, the money flows to roads, parks, public safety infrastructure, and stormwater systems across the county.

The plan spans Marietta, Smyrna, Kennesaw, Acworth, Austell, Powder Springs, and Mableton — every significant municipality in Cobb. That scope makes this something different from a typical county infrastructure program.

It is a coordinated, multi-jurisdictional capital deployment across a corridor that has been absorbing corporate relocation and commercial development pressure for several years running.

The development-readiness angle is direct. Roads get widened. Stormwater systems get upgraded. Intersections that have been holding back site plans get fixed.

For developers already eyeing Cobb County land along I‑75, a successful SPLOST vote changes the timeline calculus on projects that were waiting on infrastructure to catch up.
