This bill, titled the "Cesar E. Chavez and the Farmworker Movement National Historical Park Act," aims to establish a national historical park dedicated to preserving and interpreting the legacy of Cesar E. Chavez and the farmworker movement. It achieves this by redesignating the existing Cesar E. Chavez National Monument in Keene, California, as the new historical park. The park's primary purpose is to broaden the understanding of the extraordinary achievements and contributions made by Chavez and the movement to United States history, encompassing sites in both California and Arizona. The legislation allows for the inclusion of additional significant sites within the park's boundary, such as The Forty Acres in Delano, California Santa Rita Center in Phoenix, Arizona McDonnell Hall in San Jose, California , once the Secretary of the Interior acquires the land or enters into management agreements. The historical park will be administered under the laws generally applicable to units of the National Park System, with provisions for technical assistance, public interpretation, and cooperative agreements. Furthermore, the bill requires a general management plan within three years, which will assess potential additional sites for inclusion or linkage, and mandates a study for the designation of the 1966 farmworker march route from Delano to Sacramento as the Farmworker Peregrinacion National Historic Trail .
