As a California mapper and mapping geek:
Fortuna calls itself a city at http://friendlyfortuna.com/ , no other level
of CA government will contradict that.

The gnis:id=277520 and perhaps gnis:Class= and ele= tags are interesting,
as is census:population=.  Note the ele= in this case is meters.

Tag gnis:id=277520 is the main one to preserve, however, as the rest can be
derived.  You can also do cool lookups like:
And learn the present placename was adopted in the year 1888, the town was
also known as Fortune, Friendly City, Slide and (yet again) Springfield.

Every US Federal agency is required... required... to use GNIS, so the
gnis:id is a non-fuzzy key to a wealth of interesting data.  The non-fuzzy
part is important.

*The [gnis] database assigns a unique, permanent feature identifier, the
> Feature ID, as the only standard Federal key for accessing, integrating, or
> reconciling feature data from multiple data sets.*
