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.

Stormwater Education for Businesses

Stormwater pollution can come from many sources when it comes to business activities. One source that you may not think of is the dumpster. All sorts of potential pollutants can be disposed of in a dumpster – food waste, motor oil, metal shavings, all sorts of chemicals, and more. In order to protect those materials from reaching our waterways when it rains, there are a few easy steps to keep your dumpster in good working condition. 1. Always keep the lids closed; 2. Make sure the drain plug is in place; 3. Check for rust holes. If you have broken lids, a missing drain plug, or holes, your hauler will replace or repair the dumpster.

It’s a simple fact for many businesses that spills happen. Leaks happen, too. Whether it is dry or liquid material, barrels leak, buckets get knocked over, vehicles drip. The important thing is that businesses are prepared to react to spills and leaks in order to prevent stormwater pollution. Spill kits can be purchased at many commercial suppliers, but can also be put together very easily and without significant cost. A bucket half full of absorptive granules, a brush, a dust pan, and a trash bag is an effective spill kit for most spills or drips. A drip pan, or even a litter box, can be placed under leaking vehicles to catch the drip until it can be repaired. No matter what you choose, just be sure your kit can handle the size of a potential spill and that staff are trained to use it.

A Stormwater Pollution Prevention Plan, or SWPPP, is plan that helps businesses protect stormwater from pollution associated with work on their property. A SWPPP may be required for some industrial businesses. The basic components are a site and activity description, a site map that includes sources of potential pollution, a description of controls to reduce pollutants, and procedures for maintenance and inspection. This will allow the business to prepare for and respond to potential pollutant discharges associated with outdoor activity, and is an excellent tool for training staff on site-specific pollution prevention. For a detailed guide to developing your SWPPP, visit

Industrial businesses with no operations exposed to stormwater may be able to qualify for a “No Exposure Exclusion (NEE) from the Industrial Stormwater General Permit. A facility with a NEE has certified that they do not have these types of operations by completing the NEE checklist and performing quarterly self-inspections of the facility. This checklist can be requested from the GA Environmental Protection Division by visiting and scrolling to the bottom of the page under the heading “Forms (2012 IGP).”

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.
