Unincorporated Gwinnett is 67.3% of the county's land area and is governed by a different code, a different board and a different permit portal. Resolve the governing jurisdiction before answering any zoning question.

1. The discharge of concentrated flows of stormwater into public roadways shall be avoided. In no case shall
such concentrated flows, including flows from swales, ditches, draws, driveways, or piped systems,
exceed the allowable peak flow rates.
2. In residential subdivisions, the drainage area contributing to the peak flow rate along any property line
between lots within 50 feet of the building setback line for either lot shall not exceed two acres, unless
contained within a piped drainage system or maintained in a natural watercourse. The stormwater
conveyance shall be in a drainage easement.
