zk, all I was trying to point out here is that living along the SR-56 (whether close enough to be affected by its noise and pollution … or not) is not the only game in town to raise a family in.
I stand by my assertion that no buyer is ever forced to purchase a house with freeway noise. There is no reason for the OP to do it when he/she has choices. So my recommendation to him/her is to choose a property without it for his/her family’s long-term satisfaction. The OP asked here about disadvantages and that’s my opinion.
flu, as the “resident expert” here of Carmel Valley, aren’t there subdivisions in your neck of the woods and its surrounds which do not have freeway noise that you could counsel this OP to pick from?
Oh…. and, flu, you must know that, as convenient as it may be to the ocean, Santee has “freeway issues” in a few spots. And “heat” everywhere … along with air pollution. However, its schools are very good to excellent!
