The definition of “joint development” in FTA Circular 7050.1A is “a public transportation project that integrally relates to, and often co-locates with commercial, residential, mixed-use, or other non-transit development. Joint development may include partnerships for public or private development associated with any mode of transit system that is being improved through new construction, renovation, or extension. Joint development may also include intermodal facilities, intercity bus and rail facilities, transit malls, or historic transportation facilities.”

When FTA contributes funds, or real property or assets acquired with FTA funds, to a joint development, the project is “FTA-assisted.”
