For decades, African Americans in San Francisco have lived along the city's rough-edged southeastern bay-front, without reliable transit or fresh produce markets.

That's changing, as developers flood Bayview-Hunters Point with plans for fancy condos and a high-end shopping center ideal for young professionals.

Bayview-Hunters Point has developable land, a rarity in space-starved San Francisco, where housing is scarce and among the most expensive in the country.

But as modern dwellings crop up, many African Americans worry they will not be able to afford to stay in a neighborhood they've long called home, a place that writer James Baldwin once called "the San Francisco America pretends does not exist."

The number of African Americans has plummeted citywide, from 100,000 in 1970 to fewer than half that today.
