I'd recommend making contact with the
Allentown Neighborhood Association in Buffalo, New York. Allentown cointains the nation's largest historic district -- large brick and frame houses from the late 1800s and early 1900s, many of which are immaculately restored. The neighborhood started to gentrify in the late 1970s, and now is known for having a fairly vibrant business and entertainment district, and an eclectic, bohemian population -- lots of artists, young professionals, aging hippies, and GLBTs. (The closest Orlando equivalent, without the social service agencies, would probably be Thornton Park.)
Allentown's housing stock -- very large houses and mansions -- along with its progressive, open-minded population and proximity to downtown and the city's medical district, made it ground zero for social service agencies. The majority of the city's social service agencies, as well as group homes and halfway houses, are in Allentown. The Neighborhod Association is taking an active role in trying to slow down the flood of socal service agencies to the neighborhood, advocating zoning regulations that would require their dispersal throughout the city. I don't know what the Association is doing about agencies that settled in in the 1980s and 1990s, but you might want to contact them and find out.
