Many restrictions existed as Upper Arlington developed. Some of these involved creating open, green spaces, maintenance of parks, generous setbacks ensuring large front and corner lawns, and carefully controlled development of separate areas for businesses and multi-family housing. From 1920 to 1945, the city enforced racially restrictive covenants in property deeds. From 1930 to 1945, 77.3% of the 22 new subdivisions built in the Columbus, Ohio area either explicitly prohibited African Americans or permitted only whites.[1] In 1948, the Supreme Court ruled that racially restrictive covenants were unenforceable, and in 1968, they became illegal.
