Pomona Ordnance Depot
(Pomona Ordnance Base, Pomona Assembly Center)
 

This was the Los Angeles County Fairgrounds on the north edge of Pomona. It processed ethnic Japanese from May 7 to August 24, 1942. During that time its population reached a maximum of 5,434. Nearly everyone processed here was sent to Heart Mountain, Wyoming. On September 4, 1942 the center was turned over to the Army's Ordnance Motor Transport Agency and became known as the Pomona Ordnance Depot. The depot stocked a wide variety of ordnance materials and for much of the war serviced the California/ Arizona Maneuver Area (CAMA) (Desert Training Center), just east of Pomona. The depot had a prisoner of war camp holding about 1,150 POWs who worked at the depot

Pomona Assembly Center

The Los Angeles County Fairgrounds (Fairplex) was the site of the Pomona Assembly Center. There is no historical marker at the site. Used from May 7 to August 24, the assembly center held a total of 5,514 persons, with a maximum population of 5,434 at one time.

Evacuees confined at Pomona were from Los Angeles, San Francisco, and Santa Clara counties. Over 300 barracks were constructed at the center, along with eight H-shaped buildings with combined bathroom, shower, and laundry facilities (Figures 16.19 and 16.20). Four baseball fields are visible on the 1942 aerial photograph.

The grandstand and other fair buildings on the 1942 aerial photograph remain (Figure 16.21). The barracks area of the assembly center is now used for the fair midway, other events, and parking. Eight stable buildings are in the same location as on the aerial photograph. Since they are constructed of metal and somewhat modern looking, these may not be the same stables in use at the time of the assembly center. Further, although evacuees were housed in stables at Santa Anita and Tanforan, it is not clear if stables at other assembly centers were used for housing, too. Currently people caring for the horses live in small housing units at the ends of the stables.
