  So, then the people in the "couple of houses it's deeded in" can access the creek from their back yard essentially? That's what it sounds like your saying and anywhere that might be accessible by the public there's a big giant brown fence. I'm pretty sure a path going from someone's back yard to somewhere else doesn't make that "somewhere" else a park and it's clear from the fence huge they don't want people going down to the creek. If there's even a way to. There's no path where you mapped it going into the woods from anything either. Let alone a sidewalk. It likes where you did map the path there's a drop off that goes into a creek or something and the back of the house. It's also clear from the ESRI World imagery, which I'm pretty sure is fairly recent that mapped the curve of the path over the peoples fence and partly through their back yard. So....
  
  I'll give you the benefit of the doubt that it might look like there's a path at the spot where you drive by. If you haven't been down the path or into the actual area your saying is a park though (as you haven't. Since as you said, you just drive by there), than you can't really say if it continues into the wood or not, if it's even a path for the general public, let alone if that means the place is actually a park. It might just be a path the city had built on the side of the peoples house in case they needed to access the woods or the ditch. As I've said before, just having a path somewhere doesn't make the place a park. As I've also said before to, county GIS data can't be the only source to go off of. As it's often inaccurate. They often map things they are planning on doing and then don't remove them if it never happens (as is clear with a couple of the parks around here) and they also don't classify things the same way OSM does (I.E. landuse versus activity). So there should be more.
