Perhaps I can help a bit. Dh and I did not have children when we lived in Fresno, we moved when I had dd back "home" turns out, that was a bad idea
we are in s jersey and would rather be there then here! Anyway, Fresno is a mix. There is only one midwife that services the area, Detrah Hele, she is a good choice though. Very knowledgable and not pushy at all. Definitely recomend her. She spoke about the unassisted movement, a lot of midwives are against it since it puts them out of business, not Detrah. We chose UC and she offered us books and vids, she's a great person!
The north end of town is wealthy, that's where the new development is. Tower District has a happenin' lil strip, restaurants and neat shops, live music, great little health food store, nice neighborhoods. The Fig Garden is a beautiful area, nice homes, lots of trees, we have a friend in the rental business who lives there, she loves Fresno, her property is considered Fresno County, she has a huge yard that, if she wished, could have horses on, but she is an artist so has nice studio space. The "downtown" section of Fresno is no good. Fresno has some gang issues, we lived there for two yrs, three yrs ago and you hear about things but we were never affected by it. Fresno is considered the "armpit" of California though...
They have a great whole foods and trader joes. There is a definite green mind going on there, you just have to seek it. They have an art movement going on. They do "art hop" every third Thursday, I believe. See some nice work, around tower and downtown. I would say it's absolutely family friendly. It's very suburban there, like a very large town. Major areas of commerce and lots of single family homes. Some ppl consider Clovis, the neighboring town, to be a better area but really it's just like the nice areas of Fresno.
One thing we really liked is the location right in the middle, both north and south and east and west. The foothills just outside of town are beautiful, also Kings Canyon and Yosemite. Coast isn't too far either.
There is a large park with koi ponds on the north side too. Dont know about playgrounds.
Hope this helps a little at least! Good luck!
