In cooperation with Gwinnett County, Lilburn collects utility fees from property owners based on impervious surface area. Gwinnett uses these fees for stormwater drainage system maintenance and improvements within city limits. This agreement with Gwinnett has been in place since 2007.

The Lilburn City Council voted Dec. 11 to renew this agreement for another 10 years. The agreement includes, but is not limited to, inspections, maintenance, design, and construction administration for a variety of projects to benefit the city’s water resources. The 2018 agreement specifies that the city will maintain its autonomy in reviewing new developments. Gwinnett will coordinate with the city to identify projects and priorities, and the city administrative support responsibilities.
