horror - Why is it 'Elm' in 'A Nightmare on Elm Street'?

Elm Street is one of the most common street names in the United States. If you exclude numbers (because numbers in a title are strongly connoted to having several in a series, whether it's streets or movies), the most common names are Park, Main, Oak, Pine, Maple, Cedar, Elm. So “Elm Street” has a “generic street” feel to it.

In fiction, Elm and Pine have traditionally dominated over the other tree names that are more popular in real life. Park is even above, but the word “park” has connotations (of nature, empty spaces, that kind of stuff) that “elm” doesn't have. This points towards Elm or Pine as a generic street name for a movie.
