[quote author="frank69m" date=1230558764]Does anyone know if the Irvine company has set aside this hilly area and won't build on it? You can see it right off the 405 driving South between Jeffrey and Sand Canyon. I kinda like it but am afraid they will build more home eventually.</blockquote>
It sounds like you're talking about the Quail Hill Open Space. Before the last few big developments TIC has bequeathed a cut of their land to the city (for Turtle Ridge/Shady Canyon, it was Bommer Canyon). From what I know, Santiago Hills Phase II was going to include a monetary gift to the Orange USD to make up for the influx of new students. The North Ranch Land Gift, Jeffrey Open Space Spine (Trail), Woodbury, Orchard Hills, Woodbury East, East Orange, and Portola Springs were all within a few years of each other (all either border or cruise by each other). I'm sure you've noticed that some of these are either still in the planning/approval stages or were halted due to market conditions.
Feel free to correct me if I'm wrong on any of this, I just used to be obsessed with TIC's future projects. I used to drive down to Turtle Rock when Shady Canyon/Turtle Ridge first started being built. I'd sit/walk in and around Chaparral Park and look at the initial grading and building operations. I'd check shadycanyonupdate.com and turtleridgeupdate.com daily. Good ol' Planning Area 27. I was like a 20 year old undergrad student..(I'm nearly 28 now...SOB...but at least the degrees are done). At around the same time, Northpark Square was selling. Yes, I did and still do tour new developments whenever possible. I remember the smallest model of detached homes there (Alder Creek?) was $360k. I only remember that because how ridiculous it sounds now.
Wow, I was going to give a one-liner answer. Whoops
