What were the standardized building plans for civilian conservation corps camps?

I am doing an intensive study on two local CCC camps in my area. I have the site forms from the forest service for both camps and after a ton of visits to each camp and hours studying the maps and feature descriptions in the site forms, I know the sites inside and out. But heres the thing. No buildings are still standing. Only foundations. I know what the foundations were, but I want to see building plans on what they consisted of. Where can I find these? Even descriptions of standard plans for the buildings work for me. I can't find anything anywhere!
