ocprince,
I've lived in Irvine for about 23 years - I grew up here and I'm a product of the "highly touted" school system - (elementary, middle, high school) before going off to college. Somehow I find myself back working in the area. Honestly, I have no idea why Irvine is considered the "it" place. While the school system is very good, it by no means guarantees your child's entry to the Ivies or similar prestigious universities. If I remember correctly, each year University High sends like 7-8 people to Stanford, 2-3 to Harvard, 2-3 to MIT, 2-3 to Yale/Princeton... so around 15 out of a class of 600-700 get to go to the very prestigious private universities. Not great odds. This is for the "best" high school in Irvine. Frankly, I feel the public school system is a bit overrated - the big reason why schools like University High and Northwood rack up all these academic accolades is due to the large population of kids who come from overachieving, affluent minority families. There is so much academic pressure from the parents already - all the schools need to provide is a sufficient number of AP subjects and PRESTO - HIGH SAT averages and HIGH passing rate of AP tests = HIGH API score. You might be better off living in say Yorba Linda and then sending your kids to Phillips Exeter or Harvard-Westlake if you want your kids closer to you...
In the last 23 years, when I've told people that I lived in Irvine, I've never gotten anything close to a reaction like: "WOW, YOU LIVE IN IRVINE!?" While Irvine is gaining a reputation for a place where the "quiet wealth" reside - mostly due to Shady Canyon - it has a ways to go before people will mention Irvine the same breath as Beverly Hills, Malibu, Newport Beach, etc.
I will say this - Irvine is probably the safest OC city - it probably has the most zealous (or bored depending on how you look at it) cops in the county. I once was stopped by a patrol car - I was riding a bike at dusk with a helmet in the bike lane, but I didn't have a blinking rear red light. I forgot to mention that the patrol car flashed the sirens and engaged the loudspeaker: "PULL OVER TO THE SIDE." Half the cars on the street thought the officer wanted them to pull over - he just wanted me (a middle schooler riding his bike back home from tennis practice) to "pull over" to the curb. He got out and lectured me about the LAW, and he almost wrote me a ticket, but finally let me off with a warning.
Irvine police also had a bad rep back in 70s and 80s for being extremely racist - my middle school teacher (a little, old white lady) told the class that she was pulled over because of the condition of the van she was in, the van also had a big dog in it - the police thought that based on the rundown appearance of the van, the occupants were "unsavory characters (re: Mexican or Black)." It turns out the driver was something like the superintendent of the school district at the time and my teacher was well, a respected history teacher.
I remember Will Ferrell appeared on Letterman or Leno once back in the mid-90s and also complained about the cops in Irvine when he was going to University High.
Anyway, back to housing, those houses on 1 acre lots in Philly would be going for like 5 million+ here (in Shady Canyon). Welcome to Irvine... my family is also looking for a new house in the 1.2-2mil range and frankly, there is no way you are going to get your bang for the buck here.
