[a fool in paradise]

Today, the foothills of the Tehachapi mountains continue to house the United Farm Workers of America headquarters

Will they still be able to use the land since it will become a taxpayer funded public park?

It's already on the National Register of Historic Places:

In 2004, the National Chavez Center was opened on the UFW national headquarters campus in Keene by the Cesar E. Chavez Foundation. It currently consists of a visitor center, memorial garden and his grave site. When it is fully completed, the 187-acre (0.76 km2) site will include a museum and conference center to explore and share Chávez's work.[33] On September 14, 2011, the U.S. Department of the Interior added the 187 acres (76 ha) Nuestra Senora Reina de La Paz ranch to the National Register of Historic Places.[40]

Will it explore and share Chavez's work against illegal immigration???
