In 2024, the City of Oklahoma City prepared a revised, updated Drainage Ordinance (Chapter 16 - Drainage and Flood Controls) and a new Drainage Criteria Manual (DCM). Stakeholders were invited to review the revisions and provide comments. Once comments were reviewed the updated ordinance and manual were presented to, and adopted by, the City Council. The updated documents are available below.
