Detention/Retention Pond Maintenance

According to the City of Lilburn development regulations, it is the responsibility of the property owner to maintain a detention pond. That could be a homeowners’ association (HOA) with a detention pond on a common parcel. If there is no HOA, the responsibility for maintenance falls on the owner(s) of the property on which the pond lies. Organized neighborhood work days at the detention pond by the owner and residents can be very effective in preventing expensive repairs. 

Find more information from Gwinnett County about detention pond maintenance.

Stormwater Education for Businesses

Outdoor storage is often the answer for where to put something. However, it can also be the source of water pollution. If items stored outside are not properly closed or contained, the runoff could be contaminated and contribute to stormwater pollution. This could be considered a violation of the city’s Stormwater Management Ordinance. So be sure to cover outdoor storage and prevent stormwater pollution.

Mopping floors is an everyday occurrence in many places of business. How do you dispose of your mop water? If you dump it in the parking lot behind the building, you are contributing to stormwater pollution. Mop water should be disposed of in a mop sink of other indoor drain and not in a storm drain. This prevents water pollution and keeps Lilburn waterways clean.

Have you heard of the Industrial General Permit (IGP)? Some businesses in Lilburn require coverage under this general permit according to the State of Georgia. To find out if your business requires coverage, view Appendix D of the 2017 IGP. If you need coverage, visit GA EPD’s webpage on the IGP. 

One of the best ways to prevent stormwater pollution from an industrial business is to regularly walk your site. By becoming familiar with the area behind your building, in the back of the property and near the doorways, you will notice if something changes or is damaging, perhaps increasing the likelihood of an accidental discharge. Respond to these changes quickly to protect stormwater quality and your business.

Drainage Assistance/Rip Rap Program

Free to city residents, the City of Lilburn will deliver one truckload per year of drainage rocks. This is for erosion control purposes only, not for driveways or decoration. City public works staff will come out and assess the drainage situation and approve the delivery of rip-rap type III rock.
