KANSAS CITY, Mo. (AP) — Cerner Corporation, a Kansas City-based health care technology company, has proposed building the biggest office development in Kansas City history. An application filed with the city says Cerner is planning a 4.5-million-square-foot campus on 251 acres in south Kansas City. The plan says the $4 billion development would be built in 14 phases and completed in 2024. The Kansas City Star reports that the application filed with the city this week says Cerner is seeking about $1.2 billion in tax incentives if the office project is completely built. The company is also proposing an investment of $2.9 billion of its own resources, making financing of the project a 70-30 private-public split. The city development agency will consider the application next month.
