When reached by phone Thursday afternoon, Porter confirmed that he was referring to a grand jury investigation into some recent land purchases by the county.
"I sent them the e-mail in response to what I saw on the agenda item," Porter said.
Porter, however, offered few details about the e-mail, citing a possible grand jury investigation. He would not say which land deals he was referring to, nor would he comment on whether he suspected any misconduct by the county commissioners.
The grand jury can initiate investigations into government dealings or Porter can request one. He would not say whether he planned to ask for one. Nor would he elaborate on his statement about what he knows about the property owner.
The registered agent for Old Peachtree Partners LLC is a real estate developer and investor named Ty Robinson.
Robinson could not be reached for comment Thursday afternoon.
But attorney Michael Bowers, who represents Peachtree Partners in the matter, said he could not imagine what could be suspect about the deal.
The issue began two years ago when the county offered $1.1 million for 1.87 acres for road use. Old Peachtree Partners later learned the county intended to use the parcel to install a forced-main sewer. This, Bowers said, would preclude access to the adjoining land.
As part of the proposed sale, Old Peachtree Partners offered to sell the back area, about 15 acres along I-85, to the county at what it believed to be below fair market value — $325,000 per acre.
Those 15 acres, according to project documents, could be needed for ramp construction at I-85. Money for the land purchase would come from the 2005 SPLOST fund.
Gwinnett County Commission Chairman Charles Bannister said he could not comment on the proposed sale because it is part of an open court case. He did say he replied to Porter's e-mail, asking for a meeting. The two met on Tuesday morning, the day of the board's meeting.
"He asked for me to meet with him that morning and I did, but I can't discuss what we talked about," Porter said.
One month ago, the County Commission approved a land purchase of 33 acres near Lawrenceville for $2 million, more than twice the value set by its own appraisal. The vote was 3-1 with Commissioner Mike Beaudreau dissenting.
Porter did say that Beaudreau sent him a one-line response to his e-mail: "Thank you sir."
