The city of Maywood Park was incorporated by vote of the residents August 1, 1967. The triangular area northeast of Rocky Butte was opened as a subdivision in 1926 and, by 1940, was a fully developed suburb. In the 1960s, the OSHD located I-205 through the edge of Maywood Park, and this sparked a movement to incorporate, as some opponents of freeway construction felt city status could prevent the highway encroachment or minimize its effect. Authur M. Taylor, the developer, wrote the compiler in 1968 to say that the name was selected by his mother one wintry evening when they were remembering what a lovely spot the woods were in May. During the 1980s, there was a portland post office branch named Maywood Park.
