Several Cobb County schools will get a facelift after the Cobb County Board of Education voted recently to spend about $28 million on four separate projects.

The projects will take place in Smyrna, Marietta and Acworth.

According to the AJC, Campbell Middle School in Smyrna, Mountain View Elementary School in Marietta, Pickett’s Mill Elementary School in Acworth, and Pope High School in Marietta are involved in the overhaul.

Campbell Middle School (CMS) will receive new electrical panels in each hallway, a new heating and air conditioning system, new water heaters in the gym, new basketball goal supports, motors and cables, and new gym lighting with high-bay fluorescent lights, according to the article.

The CMS project is expected to be complete July 22 and carries a price tag of $4.432 million.

Mountain View Elementary School will be replaced entirely by Evergreen Construction of Atlanta. The project is expected to be complete May 1, 2017 and costs $23,361,000.

“Two projects involve an agreement with the Cobb County Board of Commissioners to allow the Cobb County Department of Transportation to secure a contractor for roadway improvements along Old Stilesboro Road and the property at Pickett’s Mill Elementary School in Acworth and along Hembree Road at Meadow Drive next to Pope High School in Marietta,” the AJC reports.

The Pickett’s Mill project will cost $113,799 and should be completed by the time school opens on Aug. 1. The roundabout at Pope High will be open at an undetermined time and the cost is $200,000, according to the article.

Cobb County schools recently was assigned a Triple A rating by Moody’s Investors Service — the highest credit rating available for a government entity and the first time in Cobb’s history it has earned the rating.

The AJC reports a statement released by the Cobb County School District explains the Triple A rating “reflects the district’s sizable and diverse tax base, sound reserve position characterized by conservative budgeting and formal financial policies, and an above average pension burden, mitigated by the absence of any long-term debt.”

Credit ratings represent the credit worthiness of corporations and government bodies. Ratings help determine borrowing costs and the amount of interest paid on debt, according to the article.

The Cobb district is the second-largest school system in Georgia, with close to 113,000 students.
