Civilian Conservation Corps (CCC):
Between 1933 and 1942, 135,000 California men were employed in the CCC. This included about 120,000 junior and veteran enrollees, 2,400 Indians, and 12,900 staff. Among their many accomplishments were the planting of 31 million trees and the protection of 792,000 acres from tree and plant disease.
The CCC program in California also presented an opportunity "to carry out forest fire presupression plans, as well as plans for fighting forest fires." By the end of the program, the CCC boys had devoted about 980,000 man-days of work towards such efforts.

Federal Emergency Relief Administration (FERA):
In February of 1935, 8,700 college students in California were employed in FERA's College Student Aid Program. This was a program "undertaken in order to enable young persons who would not otherwise have been able to do so to continue their education, and thereby reduce the influx of young workers into the labor market" (recall that during the Great Depression there was a large drop in the demand for labor).
Between 1933 and 1935, FERA granted $164 million to California for relief efforts (about $2.7 billion in today's dollars). FERA funds typically went towards cash relief, rural relief projects, and a wide variety of work programs.

By 1939, the PWA had contributed $103 million in funding towards 807 infrastructure projects in California (not including federal projects). In today's dollars, that's about $1.7 billion.

National Youth Administration (NYA):
During academic year 1939-1940, 576 schools and colleges in California were participating in the NYA program, employing about 20,000 students each month.
During any given month of fiscal year 1942, there were about 6,700 young California men & women in the NYA's out-of-school work program.
One of the main objectives of the NYA program was to give work experience to young Americans who were having a hard time "getting in the door" for employment and also (during World War II) to prepare them for defense work. In 1943, the California Shipbuilding Corporation in Wilmington California, wrote: "...these men (NYA) have come to us well-qualified for shipyard work, and they have proven themselves to be excellent employees. We hope your training program is to continue during the coming year and that we shall be able to count on additional men..."

During the New Deal era, the U.S Treasury built or expanded Post Office buildings in California and commissioned artists to decorate them. See the Living New Deal for examples.
Between 1933 and 1934, in Regions 14 and 15 of the PWAP (California, Nevada, Utah), unemployed artists were paid to create 55 sculptures, 105 murals, 266 oil paintings, 435 water color paintings, and other works of art, for use in public buildings and parks.
The director of Region 14 of the PWAP (southern California) was Merle Armitage, "one of America's leading advocates of modern culture." The director of Region 15 (northern California, Nevada, Utah) was Walter Heil (see "Walter Heil Papers, 1929-1973" Smithsonian Archives of American Art).
