I don't know what you mean referencing black people.

The zoning laws i mean are: commercial vs. non commercial vs. heavy industry (loud, safety requirements).

Zoning isn't as simple as that though. Zoning laws can restrict neighborhoods to with height limits, density limits, large minimum lot sizes, single family homes only, etc, with the aim of prohibiting affordable housing for undesirables.
