They are also big enough and have enough branches that kids can climb them. When I was there, someone was up in one, claiming it proudly as "My tree!"
Critter quotient: I heard several finches and saw some interesting flying and fluttering creatures too small and too fast for me to identify. It seemed slightly above average, more than the neighbor's lawn, say, but not outstanding. Thanks to the trees, the picnic tables might actually be in the shade sometimes--and by shade, I mean full, deep, cool shade.
Playground equipment: Yes. The standard yellow-and-red setup. There's also a large sandbox which, as a child, I would have found enchanting. As an adult, I confess, I wonder about the neighborhood cats.
Water fountains: No.
Parking: on the street.
Will you be able to forget you're in the city? No, but it is a quiet neighborhood and a pleasant little park for a picnic, especially if you have kids.
