It seems to end abruptly which suggests there are additional pages, like maybe a page 3. Further evidence of this is that we don't know the name of the person who wrote it.
 

Also, the writer left out part of the quote regarding "spot planning" in Answer to 7, which he got from:
http://real-estate-law.freeadvice.com/zoning/spot zoning.htm (They do not appear to allow deep linking. I found the page by using their Search box and doing a search for "spot zoning.")

In Answer to 7

"Spot zoning occurs when a small area of land or section in an existing neighborhood is singled out and placed in a different zone from that of neighboring property. For example, a park or school might be allowed in a strictly residential area if it serves a useful purpose to the neighborhood residents.

In some areas of the country the courts have found spot zoning illegal on the ground that it is incompatible with the existing land use-zoning plan or in an overall zoning scheme for the community."

Here is the entire quote with the missing part underlined:

Spot zoning occurs when a small area of land or section in an existing neighborhood is singled out and placed in a different zone from that of neighboring property. For example, a park or school might be allowed in a strictly residential area if it serves a useful purpose to the neighborhood residents.

In some areas of the country the courts have found spot zoning illegal on the ground that it is incompatible with the existing land use-zoning plan or in an overall zoning scheme for the community. Whether the exception carved out is reasonable and supported by the facts, often turns on public interest, the effect the spot zoning has on the current uses of neighboring properties, and any ramifications created by the zoning.
