Omaha's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Omaha, Nebraska, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Flood Elevation Requirements

Omaha requires new and substantially improved homes in the flood fringe to elevate their lowest floor one foot above the base flood elevation, with equipment raised to match.

Key details: Freeboard: 1 foot above base flood elevation. Applies to: new & substantially improved structures. Enforced by: floodplain management coordinator. Certification: licensed surveyor, engineer, or architect. Citation: Omaha Code § 55-658(b)(1).

Building without the required elevation certificate or freeboard blocks issuance of a certificate of occupancy, and the floodplain management coordinator can deny or revoke the floodplain development permit.

Flood Zones

Any floodplain development or substantial improvement in Omaha requires a permit from the city's floodplain management coordinator before work starts, covering new construction, fill placement and manufactured-home siting inside flood fringe and floodway overlay districts under Omaha Municipal Code § 55-655.

Key details: Permit administrator: Floodplain management coordinator. Substantial improvement threshold: >=50% of pre-improvement value. Flood fringe fill limit: 25% of flood fringe area. Violation class: Misdemeanor, each day a separate offense. Appeal path: Zoning board of appeals, then district court.

Violating § 55-655 or any floodplain standard is a misdemeanor under § 55-662, punishable by state or local law, with each day of continued noncompliance treated as a separate offense. The city can also pursue any other lawful remedy to prevent or correct a violation, independent of criminal prosecution. Decisions of the floodplain management coordinator may be appealed to the zoning board of appeals, and further appealed to district court under Neb. Rev. Stat. § 14-413.

Erosion Control

Omaha requires a grading permit before any grading, clearing, or excavation large enough to need an NPDES stormwater permit, plus a $500-$1,000 fee.

Key details: Permit fee, ≤10 acres: $500. Permit fee, >10 acres: $1,000. Issuing office: Permits and inspection division. Exemption: Agricultural grading.

Grading, clearing, or excavating without the required permit is unlawful under Sec. 32-101; the permits and inspection division and public works department enforce the permit and NDEQ coordination requirements.

Stormwater Management

Omaha prohibits dumping anything but stormwater into its storm sewer system, and puts upkeep of private drainage lines on the property owner.

Key details: Governing chapter: Omaha Municipal Code Ch. 32. Enforcement: Public Works director. Max fine: $500 per day/offense. Private system upkeep: Owner's responsibility, incl. ROW portion.

Violating Chapter 32 is a misdemeanor: up to $500 per offense, with each day a violation continues counted as a separate offense. The director can also order removal of an illicit connection after 30 days' notice and recover the city's costs from the owner.

The Bottom Line

Omaha's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Omaha is broadly strict or permissive.

Keep in mind that Omaha can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
