The Civilian Conservation Corps and the Tennessee Valley Authority had a positive impact on jobs and the environment during the Great Depression. The bill proposing the Civilian Conservation Corps was voted on and passed on March 31, 1933 under President Franklin Delano Roosevelt. Additionally, the Tennessee Valley Authority was formed on May 18 of that year to work on easing environmental pressures in the Tennessee Valley.

When he was governor of New York he created a TVA-like public works program on a smaller scale and was successful. As a result he was encouraged to expand that idea to the Tennessee Valley. TVA has managed to employ many people and remain largely self-sufficient by selling electricity to millions of people in the surrounding area. The sale of electricity was made possible by the Public Utility Holding Company Act (PUHCA), which prevented monopolies through public ownership by the government. These programs continued to be very successful during the Great Depression, and on August 31, 1935, the number of workers in the CCC reached its peak.
