Citizens will have one last chance to voice their concerns about the requests Atlanta Motorsports owner Jeremy Porter has made that include longer hours for go-kart usage and lighter noise restrictions at the park. The Dawsonville City Council on Monday voted to hold off on making a final decision on requests by Porter until after a meeting next month. The May 15 meeting will be a public hearing that will begin at 7 p.m., after the city's regularly scheduled work session that will begin at 5 p.m. The council also made it clear that its wishes to further investigate the noise levels out at the park on Duck Thurmond Road and at the residences in the area.
