One thing they can do to address what you are talking about is require all signs to be bilingual where a foreign language is used.

This is as they do in Canada with the use of French and English in most labeling and in China where English language on a sign can only be half the height (size) of the Chinese characters on the sign.

There are over 100 languages spoken in New York city. It isn't practical.
With the exception of Little Odessa and Borrough Park for Russian, and the Chinatowns, the result would be Spanish signs everywhere. That would give de facto preference to Spanish.

The have signs in Canada because it is a bilingual country that has given up on a national culture. That is exactly what virtually all conservatives oppose in the US.
