The Metropolitan Entertainment & Convention Authority (MECA) is a 501(c)(3) non-profit organization that builds and manages public venues in Omaha, Nebraska. After a vote of approval from the citizens of Douglas County in May 2000, MECA was formed to construct and operate CenturyLink Center Omaha. Formal operations commenced on August 25, 2000, with the signing of a 99 year Lease and Development Agreement with the City of Omaha, and CenturyLink Center Omaha opened in September of 2003. At the City’s request, MECA later assumed operations of the Omaha Civic Auditorium in July of 2004. MECA also assumed operations of TD Ameritrade Park Omaha in April 2011.
