Interesting! Good catch. They have the same name but appear to have different boundaries. What made me research this in the first place is a streetlight banner at Clybourn & Milwaukee calling the area the Hi-Fi District, which apparently means Historic Financial District, which is apparently contiguous (or so I thought) with the East Side Commercial Historic District. Strange and interesting that we should have two different sources with the same name but different boundaries. Yours is from 1986 and typewritten, but mine is undated and typeset in a word processor: https://city.milwaukee.gov/ImageLibrary/Groups/cityHPC/DesignatedReports/vticnf/HDEastSideComm.pdf Can historic districts' extents be updated/revised? I dunno. What do you think we should do? (I wouldn't have drawn mine in if I'd seen yours first; sorry I didn't!)
