Okay, on this one, I’m taking a chance because I honestly don’t know the enci/cbad market, but with regard to volume, isn’t that something that’s sort of a function of itself?
In other words, as an area grows, the growth drives further growth. This continues until, well, it reverses.
You make the point yourself, NCC used to be a bit more primitive than it is now. Roads didn’t go through, areas weren’t as built up. They didn’t have a costco. This is not that different from Chula Vista and the Temecula Valley. Growth also brings more local employment to the area, making it even more viable as a place to live. It was also cheaper.
So anyway, it grows and grows until someplace else becomes more attractive and people start going there, then the volumes settle down to a steady state. And, of course, all areas go through such cycles (gentrification and whatnot), but it seems hard to deny that the combined zips you provided haven’t been through a bit of a boom decade (moreso than say 92124).
Encinitas proper has been less subject to this it would seem. What do those numbers look like?
