MARIETTA — The Town Center Area Community Improvement District agreed to add several properties to its district during its monthly meeting Tuesday.

The vote to approve the annexation resolution was unanimous among those present, with board members Skip Spann and Jeff Gramlich absent.

Lanie Shipp, the CID’s executive director, said that for a property to be annexed into the CID’s six square miles, the property owner must first agree to the annexation, after which the CID board approves a resolution to do so. Finally, the Cobb Board of Commissioners must approve the annexation before any commercially zoned property can be taxed the extra five mills for being in the CID.

Shipp describes it as a common practice.

“You really try to solidify the entire area,” she said. “Some places, like some of these service stations that are owned by corporations outside, they’re very hard to get a consent form because if they’re in California, they could care less what we’re doing here, and to ask them to tax themselves unless they’re familiar with the area and familiar with what the CID is doing, they’re not likely to even pay attention to that request.”

Many of the property owners that ask to be included in the CID have properties in other CIDs in metro Atlanta, she said.

“They’re likely to come in without any problem at all because they realize the advantage of doing it,” she said. “Commercial property owners know that the CID tax comes back to the CID district to be used to accelerate infrastructure improvements within the CID district, giving the property owners a direct benefit.”

The board voted to annex properties owned by Robert McCamy, who has six one-acre, residentially zoned, undeveloped lots by Interstate 575 and Chastain Road.

The board also added two lots owned by VKEP, a family corporation of CID board member Kelly Keappler. The lots are both commercially zoned, undeveloped tracts, Shipp said. One is a two-acre parcel on Chastain Meadows and the other is a 27-acre parcel on Big Shanty.

Board member Kerry O’Brien said he wanted to be sure that whenever the residential properties joining the CID are rezoned commercial, the extra five-mill tax is collected from them. Shipp said this was easily tracked through the tax assessor’s office.

A mill is $1 for every $1,000 of assessed value.

The Cumberland CID will conduct its monthly meeting at 7:30 a.m. on Thursday in the offices of the Cobb Chamber of Commerce.
