The Atlanta Falcons informed the Georgia World Congress Center Authority in a letter today that the preferred south site for the new stadium is not feasible at this time because the needed property hasn’t been acquired and said the focus should now turn to the alternative site north of the Georgia Dome a person familiar with the situation told The Atlanta Journal-Constitution.

UPDATE: The GWCCA board early this afternoon voted to allow the Falcons to begin due diligence work including a soil study on the north site.

The south-of-the-Georgia Dome site — at the corner of Northside Drive and Martin Luther King Drive — was identified in an agreement reached earlier this year by the Falcons and the GWCCA as the “preferred site” for the stadium. However building on that site requires buying two churches Mount Vernon Baptist and Friendship Baptist and the Falcons had the option of shifting to a study of the north site if the property was not acquired and the south site deemed feasible by Aug. 1.

No deal has been reached with the churches.
