  I see no "actual park about a block from here."
  
  Have you never experienced a private park like this, owned by a homeowner's association?  (Similar to Hidden Glen in Scotts Valley, https://www.openstreetmap.org/#map=18/37.03518/-122.03618 , though that's a bit more "shoehorn-shaped" than this/these are.  But similar to the "wraps around people's backyards."  It's a park.  A private park, but a park.  Ask the people who live there.
