Quite a bit of Richland housing: https://www.ci.richland.wa.us/home/showdocument?id=2750 https://www.ci.richland.wa.us/home/showdocument?id=2750 I count 3513 "alphabet houses" from that document, plus 1342 unlettered prefab houses and 17 dormitories for women. The Tri-Cities area was a very small agricultural community before the Manhattan Project.
