Do the latest NGS topographical maps show the city limits properly?
Those are public domain

I did check the node change made here to see if it might be one of
them. However, according to the node history
https://www.openstreetmap.org/node/373647840/history#map=13/37.3600/-121.9066
the original source of this node was a changeset quite a while ago
with a description "adjust boundaries based on san jose city map,
bing, and common sense ". It therefore would be great if a local
could check it if possible.
I'm fairly local (SJC is my "home airport") yet I'm not finding
easily-available San José City Limit boundaries in an
ODbL-compatible format which I could use to relatively quickly
repair the damage. (The user mk408 has a history of "making it up
as he sees fit" OSM data entry which many have disputed or
redacted, for example, many years ago he made MANY roads in the
entire South Bay region — Campbell, Los Gatos, Monte Sereno,
southern San José —into highway=tertiary roads, and that remained
very questionable until it slowly but surely "healed itself,"
again, this took months-to-years). There are some geo data at
http://csj-landzoning.appspot.com/index.html which indicate the
present OSM data are "largely correct," the exception being that
the area directly over the northern part of the airport do not
include the "leg" that "covers" runway 12L/30R and that the acute
angle over taxiways V, W and W1 is more like "aligned with these
taxiways, rather than cutting across them." You really have to
see them rather than expect that I can describe them with text.
They are, again, "mostly correct" but could use some rather minor
correction.
As I bumped into somebody on a plane on my way back from SOTM-US
Seattle (2016) who works in the San José City Hall and when she
met me was bowled over at the coincidence that I was the very
person sitting next to her drinking gin and tonic who entered into
OSM most of Santa Clara County's bikeways/bicycle infrastructure
and network=lcn routing (which the city office found "extremely
helpful" — her words), it's conceivable that I might be able to
use that to sway release of some data which could be forthcoming.
While I don't know quite who to call, exactly, if somebody wants
to "release to me" ODbL-compatible data which need to be
harmonized with what are now in OSM, I'll volunteer to be the
"nexus of citizen entry" to assure they find their way into our
wonderful map. Send me a pointer to the data, assure me they are
ODbL-OK and I'll "merge" these into OSM.
