An ongoing credit on the stormwater fee (not a one-time rebate): up to 10% for installing a residential rain garden of native vegetation, scaled by the share of impervious area served (40% cap across all credits). Reapply every 5 years (Gwinnett County DWR; last verified June 2026).

An ongoing credit on the stormwater utility fee (not a one-time rebate): up to a 50% reduction for on-site features such as rain gardens that reduce runoff or improve water quality. A dedicated single-family residential credit application confirms homeowner eligibility (Macon Water Authority; last verified June 2026).

An ongoing credit on the stormwater fee (not a one-time rebate): 20% if all impervious surface is retained on-site, 10% if more than 50% is retained, via approved practices including rain gardens, cisterns, pervious pavement, and infiltration areas (City of Powder Springs; last verified June 2026).

An ongoing credit on the stormwater utility fee (not a one-time rebate): up to 10% off Rockdale County's flat $125.40 residential stormwater fee for installing a rain garden or bioretention facility of native vegetation, scaled by the share of impervious area treated. Credit lasts 5 years; reapply at the end of the term (Rockdale County Stormwater Utility Credits Manual; last verified July 2026).

An ongoing credit on the stormwater utility fee (not a one-time rebate): the City's Residential Environmental Technologies credit covers rain gardens along with cisterns, pervious pavement, and infiltration areas, crediting 100% of the fee in the first year and 20% in years two and three, renewable at the end of the 3-year term (City of Roswell Stormwater Credit Manual; last verified July 2026).

An ongoing credit on the bi-monthly stormwater user fee (not a one-time rebate): the City's Residential GI/LID Practices credit covers rain gardens, bioretention cells, and xeriscaping (removing or replacing at least 20% of existing lawn), crediting 20% off the fee for three years. Renewal is not automatic: the customer must resubmit the application package before the credit expires, and the same qualifying requirements apply to the renewal (Credit Manual, page 6, "Stormwater Utility User Fee Credit Application Procedures, Item 9"). Initial billing under the new fee began with utility bills dated after September 1, 2026. (City of Savannah Stormwater Utility User Fee Credit Manual, adopted January 22, 2026; confirmed by Terri Harrison, Director of Advanced Metering Infrastructure, August 2026; last verified August 2026.)
