Stormwater Runoff Controls - Omaha City Bylaws
Omaha, Nebraska requires developers to manage stormwater runoff to protect drainage systems, waterways and public health. This guide explains local controls, the permit process, enforcement pathways and practical steps developers must follow before and during construction. It highlights the city office responsibilities, where to find official rules and the typical documentation expected for erosion and sediment control plans.
Overview of Controls and Applicability
The City of Omaha regulates on-site stormwater controls, erosion and sediment control during construction, and post-construction stormwater management for new developments and redevelopments. Local requirements work alongside state NPDES stormwater permits for construction and municipal separate storm sewer systems (MS4s). [1]
Permit Process for Developers
Developers typically must prepare a stormwater pollution prevention plan (SWPPP) or equivalent erosion control plan, show proposed post-construction stormwater management practices, and obtain any required city approvals before grading or building permits are issued. The city reviews plans for compliance with local standards and may require construction sequencing, stabilization timelines, and long-term maintenance agreements.
Applications & Forms
- Required plan: stormwater pollution prevention plan (SWPPP) or city-prescribed erosion control plan; specific city form or template not specified on the cited page.
- Permit fees: fee schedules not specified on the cited page; check the permitting office for current rates.
- Submission: submit plans with building/grading permit applications to the Planning and Development or Public Works department as directed by city instructions.
Design Standards and Best Practices
Omaha enforces technical standards for sediment controls, stabilized entrances, storm inlet protection and post-construction best management practices such as detention, retention, infiltration, green infrastructure and flow-rate controls. Developers should reference the city technical guidance and applicable state NPDES requirements when sizing and detailing facilities. [2]

FAQ
- Do developers need a separate city stormwater permit?
- Developers must meet city stormwater requirements and often must provide a SWPPP or erosion control plan; a distinct city stormwater permit form is not specified on the cited page.
- Who inspects erosion controls?
- Public Works and Planning/Development staff perform inspections or respond to complaints; contact information is in the Help and Support section below.
