DeKalb County has signed a contract with the architectural firm that will draw plans to build 63 new hangars at DeKalb-Peachtree Airport.

The $321,000 deal with the LPA Group calls for the firm to develop construction plans and specifications for the hangars to be built along a crosswinds runway near the airport’s Clairmont Road side.

The $5.6 million project likely means more planes in and out of PDK, the state’s second-business airport. It also takes up the only available space for a central terminal, effectively killing a chance for commercial airlines to set up shop there.

The design, which is being paid from the airport’s enterprise fund, is expected to be done by year’s end. Construction could begin by next summer.
