Hello Svetlana,

Respectfully, the name of this park certainly isn't the descriptive "St. Andrew's Heights & West Hillhurst Off-Leash Area", nor is it spelled in all-caps. You also deleted the name from the park area, but added a name back to the patch of scrubby brush in the middle of the park; I suspect that was not your intention.

I've restored the "Karl Baker" name to the park area, and updated the tagging of this area to `leisure=dog_park`. I've added a 'fix-me' note (using the `fixme` tag) asking if someone can confirm the name's source. See https://www.openstreetmap.org/changeset/169783392

Just a friendly heads-up: even if a name is not official it does not mean it's not valid. It doesn't need to be "authorized" to be true. I'm probably very similarly skeptical of 'unofficial' names as you are, but we also have a tag for "official name" if it happens to have an official name that isn't the same as its most common one.
