As an independent municipality (18652005) Elkhorn was founded in 1865. It was
platted in 1867 when the
Union Pacific Railroad was extended to that point. Elkhorn was first incorporated in 1872. However, after a period of financial struggles, Elkhorn became unchartered. Elkhorn was incorporated again on December 30, 1886. In April 1895, a fire started in Main Street, causing ten buildings to be damaged and a loss of $28,000. The fire was started due to a Union Pacific train engine. In 1993, Elkhorn attempted to annex Chapel Hill. The annexation was blocked by two Chapel Hill residents after filing a lawsuit against Elkhorn. In 1995, their arguments were rejected by the
Nebraska Supreme Court and the annexation was approved. Annexations were done primarily to avoid annexation by
Omaha. Municipalities with a population of less than 10,000 could be annexed by larger cities. In May 1996, it was announced that Elkhorn would be annexing Rogers Ridge, Ramblewood, Quail Ridge I and II, Skyline Oaks I and II, Wadsworth, and Wright Subdivisions. These annexations would increase Elkhorns population from 3,800 to 5,000. In August 2001, Elkhorn annexed Greenbrier, Arbor Ridge, Fair Meadows, Winterburn, and Nrohkl. By 2004, Elkhorn had reached a reported population of 7,500 people.
Annexation (20052007) Elkhorn was an independent municipality until it was annexed by the City of Omaha in 2005. In an attempt to prevent the annexation, Elkhorn almost simultaneously annexed several surrounding subdivisions in an attempt to bring the city's population above 10,000 citizens; a 1917 state law limits Omaha's annexation power to neighboring communities not over 10,000 in population. On January 12, 2007, the
Nebraska Supreme Court ruled in favor of Omaha, saying "…we conclude that Elkhorn ceased to exist as a separate municipality on March 24, 2005, the date that Omaha's annexation ordinance became effective." The
United States Supreme Court denied Elkhorn's request to hear the case on February 22, 2007. Omaha Mayor Mike Fahey said he tried for years to work with Elkhorn, whereby Elkhorn would not be annexed if the city did no further annexing of its own. Elkhorn representatives did not consider that a fair proposal and refused. Omaha began the process of annexing Elkhorn. The two municipalities went to court as Elkhorn attempted to block the forcible annexation by Omaha. It was not until after losing the first round in the courts that Elkhorn offered to reach an agreement with Omaha. Omaha, having won in the courts and already financially invested in the court fights, refused to deal with Elkhorn and continued the annexation process. The final Elkhorn city council meeting was held February 27, 2007. Elkhorn ceased to be an independent
municipality on March 1, 2007.
As a neighborhood of Omaha (2007-present) On April 26, 2024, Elkhorn was struck by
a large, long-tracked EF4 tornado. Hundreds of homes and businesses were damaged or destroyed. ==Demographics==
