Understanding the conflict over the Atlanta Beltline

At issue is a contract first brokered in 2005 between former Mayor Shirley Franklin and then-Superintendent Beverly Hall that established the Beltline tax allocation district, or TAD.

Under the agreement, which was amended twice in 2009, Atlanta is required to make $162 million in a series of fixed payments to APS in exchange for using a portion of school taxes for Beltline development.

But citing effects of the recession, the city was nearly a year late in paying a $1.95 million debt in 2013, and then withheld the next two scheduled payments worth $13.5 million combined. City and school leaders have been at odds as they attempted to renegotiate the contract, and the Atlanta Beltline has struggled to secure new loans or issue bonds because of the financial uncertainty.

On Friday, Mayor Kasim Reed’s administration and APS leaders announced a new agreement in how to fund the revitalization project.

Standing together near the Atlanta Beltline’s Eastside Trail Friday, city of Atlanta and Atlanta Public School officials announced a long-awaited deal over funding of the popular trails and parks project.

“The smoke has come from the house of cardinals at the Vatican. We have a deal,” Mayor Kasim Reed declared to cheers.

Resolving the issue signals “a renewed partnership” between the city and the school system, APS board chairman Courtney English said.

The news brings to an end years of conflict between Reed and school leaders that began in 2013, when the Beltline was first unable to make required payments to APS in exchange for using school taxes for its expansion.

Under the new agreement, the school district will get significantly less money than originally planned — about half. But what it gains, district leaders say, is more certainty that it will actually get paid.

More broadly, the deal brings stability to the Beltline, which has struggled to grow amid financial uncertainty.

Instead of a series of payments totaling about $162 million through 2030, the new deal calls for Atlanta to pay $73.5 million over the same time period, according to APS board chairman Courtney English. In addition, Atlanta would pay all past debts, a figure APS officials placed at about $14.8 million.

Atlanta already made an initial $9.1 million payment toward that debt in December and is expected to pay another $5.8 million in February. The city would also make an additional $10 million payment next year, according to APS.

The city will give the school district the Bankhead Courts property, a now-vacant piece of land owned by the Atlanta Housing Authority. The agreement also calls for the school district to allow the city to refinance debt connected with another project — the Eastside Tax Allocation District — and for the school district to be paid $593,000 in money owed from that district.

Finally, APS will now be paid through a trustee, instead of from the city. That means that the school district will automatically be second in line to get paid — right after bond holders, English said. The agreement shortens the time limit before the school district can take legal action if the city doesn’t pay.

English said the deal is more in line with Atlanta’s post-recession economy.

“I think we got a good deal for APS, one that allows us to help our kids right here right now,” he said.

The dispute had led to clashes between Reed and APS officials, including former superintendent Erroll Davis, current superintendent Meria Carstarphen and English. City and APS attorneys also traded threats during the conflict, which also saw Reed and Council President Ceasar Mitchell at odds.

The school board is scheduled to vote on the agreement tonight. The deal is expected to head to the Atlanta City Council for approval on Monday.
