These are great baseball/softball fields!
I'm not a City of Peoria resident and I don't visit this park for anything other than my son playing youth baseball - both in club baseball and district little league tournaments.
The Rio Vista baseball/softball fields are some of the nicest, best maintained fields in the valley. It's obvious the city cares about this park and their sports programs. The grass is always green, cut and simply wonderful. The infields are well maintained, well striped and watered, with one exception - the pitching mound on Field #7 has deteriorated to the point of being a pitching bump. As of June 2011 It's far from the 12" height required for Little League play. That being said, it's still a nice grass infield to play on.
I've had the opportunity to work with the staff at Rio Vista park too, just to communicate baseball scores during District 2 little league tournaments. The staff is a joy to work with.
Thanks for a wonderful place for the kids to play baseball!
