Yes that is correct. But this proposed ordinance specifically dealt with hunting within a certain distance from a house - not discharge of a firearm. And hence my comment.
You should read the actual resolution. As proposed right now, it bans the discharge of "any rifle" within 250 feet of a residence for any purpose including "for purposes of hunting." So it is a general ban on the discharge of rifles, not an [overt] attempt to regulate hunting.
Clarke County has a similar rule, and the state has had no problems with it.
