Serious question: where did the "Springville Avenue Extension" name come from?

Every street sign along the artery built during the subds' development says "M.B. Villar".

Meanwhile, Waze and Google Maps say "M.V. Villar", which from what I can remember is a case of "wikitruth" wherein Google absorbed Maps business pages with that typo on, then renamed the street altogether on the world's #1 mapping platform...?

I think we should relegate this name to `official_name=` if it's ever actually in the docs, I don't know any businesses or residents using the Ave. Ext. name.
