Stormwater Drainage Manual
The Stormwater Drainage Manual establishes stormwater control requirements for all new public and private development and redevelopment in the City of Columbus. It requires post construction stormwater controls for both water quality and water quantity.
In 2012 the Department of Public Utilities updated the Manual. Major changes can be found in this summary.
The Department also made changes to the stormwater credit rule. The major changes to the rule are the inclusion of a Green Infrastructure Credit (Article 6), a Clean River Fee Credit (articles 3 and 8.3) and the Residential Backyard Conservation Program (Article 7).

STREAM CORRIDOR PROTECTION ZONES
The City’s Stormwater Drainage Manual requires developers to establish Stream Corridor Protection Zones along stream corridors when new development or redevelopment is proposed on property where streams are located. Stream Corridor Protection Zones consists of the stream and the riparian area along the stream and are protected through either deed and plat restrictions, easements or by City ownership. The purpose of the Stream Corridor Protection Zone is to allow the natural, lateral movement of open water courses, provide sufficient area for flood conveyance, protect water quality and prevent structures from being impacted by natural streambank erosion.
