The answer is Public Works Administration and Civilian Conservation Corps.
As soon as Franklin Roosevelt entered the White House in 1933, he put the country to work towards his New Deal programs. That same year, he established the Public Works Administration, a government agency that sought to reduce unemployment, increase purchasing power and improve public welfare through the construction of highways and public buildings. The Civilian Conservation Corps was also established in 1933 with similar purposes, this organization aimed to give millions of young men employment on environmental projects, such as the plantation of trees, construction of trails and shelters and works in forest and fields.
