peralta hills is sort of like woodsy version shady canyon. entirely custom estates except without building restrictions. some of the homes in that neighborhood are the most amazing i've seen anywhere in oc. this is where the old money built their custom huge estates in the 80s and early 90s before the glorification of the so-called california riviera.
i grew up in north oc and still lived there for quite a while before moving to irvine. the commute all the way down to newport ctr was actually not bad (although i'm always on the road before 8). maybe 20-25 minutes, but constantly moving. i took santiago canyon over to jamboree. most of that is just like a highway anyways. plus theres the option of the toll road which is only 75 cents on that route, although a bit more (but even faster) if you connect from the 91. quite honestly there are some days it takes me longer getting back to woodbury through the service streets of irvine.
for that reason i would totally consider north tustin, orange hills, vp, and as far as anah hills in a heartbeat when the S.O. and i are done with the convenience of irvine and looking for bigger and better housing.
