The MARTA board of directors voted at its Sept. 12 meeting to move forward with a review of the city’s audit released last month that claims the transit agency could owe the city up to $70 million.

The board approved the review as recommended by State Rep. Deborah Silcox (R-Sandy Springs), chairperson of the General Assembly committee that supervises MARTA’s budget.

In a letter to the board, Silcox raised concerns about the findings made by Mauldin & Jenkins, the firm hired by the city of Atlanta last year to audit the More MARTA transit expansion program.

She recommended a review of Mauldin & Jenkins’ findings by the accounting firm KPMG as part of its audit for the state.

There was no discussion about the city’s audit at the Sept. 12 meeting. But at the MARTA business management committee meeting last month, several board members, including chairperson Kathryn Powers, agreed with Silcox’s concerns.
