Local zoningPresent (with conditions)

The zoning law is adopted under the zoning provisions of the New York Town Law.
The source is a text PDF with a file date of 2-15-22 and amendment notes through 2008 in the text; no separate effective date was found, so effective_at is null. Later amendments may exist.
