The CityArchRiver 2015 design for the Arch grounds includes many components that fall under the jurisdiction of different agencies. Given the nature of the Arch grounds, those agencies are different parts of the federal government.

As of last October, the National Park Service and the Federal Highway Administration have signed a Memorandum of Understanding to help coordinate the various components of the CityArchRiver 2015 plan. The NPS has also invited MoDOT as a cooperating agency for their environmental documents.

Below is an excerpt from the MOU document detailing the various CityArchRiver 2015 project components and the jurisdiction/lead agency under which is falls.
