My input... there is the consideration of the soil disclaimers for the VOC homes, but there have also been concerns of toxic plumes that envelope various tracks of Irvine Villages. Irvine public schools are fantastic so there really isn't a need to put your kids in private schools. If you live in a TUSD zone that has bad schools and you're going to send your kids to private schools, you'll have to think of that monthly/yearly cost also. There's good/bad to Irvine/Tustin.
