Hi, I've tried to map what is here. The park in the sense of trees, grass, etc. only goes in a narrow strip along La Sarena Way; divided by a fence and a change in elevation, the rest consists mostly of dirt and low plants that I believe is an aquaduct maintenance/access area, which has a "no trespassing" sign on one side but not the other, hence the note (as far as I can tell the position of the sign doesn't matter and I've just gone ahead and tagged that whole area access=no).
