My neighbors yard is higher than my yard by about 3'. His property

bad rain (like what we just got in the Northeast).

Is this the natural/original grade or was the house next door built
after yours and the drainage changed? If the latter, it may be
possible to require the neighbor to resolve the problem.

Guy bought empty lot next to us and tried the same trick -- finally
took a letter from the lawyer to really get his attention, but he had
to rearrange the initial idea for his driveway drainage to not
impinge.

It depends on local zoning rules/requirements and what the local
attitude towards enforcement of same, but in general it's a tenet that
new construction can't change runoff to the detriment of existing.
