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).
