Caucasian race
Between 1935 and 1944, William Boeing and his wife Bertha set aside a large tract of land north of the Seattle city limits for subdivision, including the future communities of Richmond Beach, Richmond Heights, Innis Arden, Blue Ridge, and Shoreview. The Boeings placed racially restrictive covenants on their land to enforce segregation, forbidding properties from being "sold, conveyed, rented, or leased in whole or in part to any person not of the White or Caucasian race." Non-whites could only occupy a property on the land if they were employed as a domestic servant "by a person of the White or Caucasian race."
