If you think $1300's for a 1BR or $1700's for a new 2BR on the border of Newport and Irvine is too much, pay $7 a day in tolls and commute to Aliso, or live in an old moldy unit in Costa Mesa to save $200/mo.
As with this and every other gated community I have lived in before, the gates aren't closed 100% of the time. Even when they are closed, you can always follow someone in. Even the communities with guards at the gates have side entrances where you can do that.
I wouldn't make my decision on where to live on what hours the gates are closed, but on the area of the community (safest area in Southern California) and how nice the units are on the inside (new and upgraded). Everyone can agree that Turtle Ridge is great in both those aspects.
I for one have been very pleased with my stay so far. Everyone in the leasing office has been great with anything I have asked of them too.
