Gwinnett County northeast of Atlanta is one of Georgia's most populous counties and sits in a tornado-prone corridor. The April 2020 tornado caused significant damage across suburban communities. The county's rapid development has increased impervious surface and worsened flash flooding in its creek systems during severe thunderstorm events.
