just went to go see these. look pretty nice. Plan 2 was my favorite, it had a more practical first floor layout (great room/kitchen) that allows you to use that wall that borders the stairs as the entertainment center, i would not get the fireplace option. The first floor layout in plan 3 is a bit wierd. the best set up is probably how they have the model set up, with the fireplace and the TV over it, otherwise the TV angles may not be so great. The bathroom in the plan 2 is great, i love that no door setup.
The 133 noise is not as loud as up by the Sevilla location, couldnt really hear the portola pkwy noise too much since it seems that the homes are kind of sunken in relation to Portola and they do have a good amount trees running along portola that probably helps with the noise. Im with USC, if i got one of these it would be plan 2. It is essentially like Sevilla plan 3 but with a driveway.
