Summary
Omaha bans letting noxious weeds or nuisance vegetation grow on any lot, using both the state noxious-weed list and its own list of aggressive, invasive landscape plants.
Nuisance weeds include the following: (1) Any noxious weed as defined by the State of Nebraska, which may change from time to time... (2) Any vegetation, native or non-native, that has been identified as a nuisance within the urban landscapes of Omaha. These plants have been identified as fitting one or more of the following growth characteristics: Aggressively spreading, prolific seed producers, undesirable, compete with landscape plants, fast growing and competitive, undesirable spines or seeds.
Full Breakdown
City code defines two tiers of banned vegetation: any weed on Nebraska's official noxious-weed list, plus a separate Omaha-specific list of plants (native or not) that spread aggressively, produce prolific seed, or otherwise crowd out landscaping. Both lists are maintained online by the parks, recreation and public property department and can change over time. Property owners who let these plants (or any nuisance vegetation) exceed 12 inches in height are in violation and face abatement plus escalating fines under the companion weeds-and-litter provisions.
Violations & Fines
First offense $75; second offense at the same address $150; third and later offenses $300, rising to $500 if a violation recurs within 24 months of two prior ones.
