Like the Burbank Airport, there was a camouflage net put over detention camp as the center operated under military contract. On August 4, 1942, a riot broke out at the Santa Anita Assembly Center. The camp closed on October 27, 1942.Once the permanent concentration camps were built most of the Santa Anita Assembly Center inmates transferred to Heart Mountain Relocation Center, Rohwer War Relocation Center, Granada War Relocation Center, and Jerome War Relocation Center.
  In California, thirteen temporary detention facilities were built. Large venues that could be sealed off were used such as fairgrounds, horse racing tracks and Works Progress Administration labor camps. These temporary detention facilities held Japanese Americans while permanent concentration camps where built-in more isolated areas. In California Camp Manzanar and Camp Tulelake were built. Executive Order 9066 took effect on March 30, 1942. The order had all native-born Americans and long-time legal residents of Japanese ancestry living in California to surrender themselves for detention.
