Thomson Motor Centre won a more than $560,000 contract to provide the Chargers.
In the past, the sheriff’s office used Ford Crown Victorias as patrol vehicles, but Ford plans to discontinue the model.
Already the sheriff’s office has four Chargers in service, and they have performed well, according to officials.
Also at the meeting, commission members approved funds for the development of a plan to build a BMX racing track at an Evans park.
For a $4,800 fee, Augusta-based architectural firm Johnson, Laschober and Associates will develop a site plan for a BMX track and skate park at Blanchard Woods Park on Blanchard Road, according to county documents.
The site plan for the proposed facility will include layout, spectator viewing areas, staging areas, pit areas, size and location of the track and skate park, according to a letter sent to county officials from the firm.
The original master plan for the park included designs for a BMX track and skate park, said county Community and Leisure Services Director Barry Smith.
More than 80 percent of BMX enthusiasts in this area live in Columbia County, Smith has said.
The Augusta area currently has a BMX track in a dilapidated neighborhood near Lake Olmstead Stadium, but some Augusta BMX officials have said that the location is dangerous.
They told commissioners that the track often is vandalized and that a small office is riddled with bullet holes.
