Full Breakdown

Omaha Municipal Code § 55-655(a) bars any person, firm or corporation from initiating floodplain development or a substantial improvement, or causing the same to be done, without first obtaining a separate floodplain development permit as defined in section 55-654. S. Army Corps of Engineers and the Nebraska Department of Natural Resources before any watercourse alteration, and keeping permanent records of the lowest-floor elevation of every new or substantially improved structure in a special flood hazard area. An applicant must file a written application describing the proposed development and its estimated cost, the legal description of the land, the intended use, construction plans showing existing and proposed grades, and the proposed lowest-floor elevation, signed by the permittee or an authorized agent (§ 55-655(c)).

New and substantially improved structures need an elevation certificate from a licensed surveyor, engineer or architect (§ 55-655(d)); nonresidential structures that are floodproofed instead need a floodproofing certificate from a licensed engineer or architect; any development in the floodway needs a no-rise certification from a licensed professional engineer (§ 55-655(e)-(f)). Under § 55-657, an improvement counts as 'substantial' once its cost equals or exceeds 50 percent of the structure's pre-improvement market value, and fill placed in the flood fringe for new development is capped at 25 percent of the flood fringe within the project area (§ 55-657(g)(1)). 00 of coverage.

Violations & Fines

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.

Frequently Asked Questions

Does every home improvement in an Omaha flood zone need a permit?

Only if it counts as a 'substantial improvement': the cost of the addition, alteration or repair equals or exceeds 50 percent of the structure's market value before the work began (§ 55-657(a)(1)). Below that threshold no floodplain development permit is required, though flood-fringe fill and floodway work always need one regardless of cost.

Who reviews and issues Omaha's floodplain permits?

The floodplain management coordinator in the planning department, appointed under § 55-655(b)(1), reviews every application, verifies lowest-floor elevations, coordinates with FEMA and the Army Corps of Engineers, and maintains the city's permanent flood-hazard permit records.

What if I can't meet Omaha's flood-elevation standards?

You can apply to the zoning board of appeals for a variance under § 55-660. The board weighs flood danger, alternative sites and public cost, and must give written notice that building below base flood level can push flood-insurance premiums up to $25.00 per $100.00 of coverage.

What's the penalty for building in an Omaha flood zone without a permit?

It's a misdemeanor under § 55-662, with each day of the violation counted as a separate offense on top of any state-law penalty. The city can also take other lawful action, such as a stop-work order, to remedy the violation regardless of prosecution.
