Fight to save Glenwood update

Went to the zoning office last week and found that we (my street) are zoned RM12,which means that a developer could put a 12-unit multi-family structure on one acre of land. It seems that this means that there would be no zoning fight or warning, developers could just start. An acre is 208 feet by 208 feet. There is one such apartment structure on my street already, about four houses up from me. I am trying to continue to contact different folks in the city about this, and UNCG folks that I have contacted don't know anything about it.
