It's very interesting that you post this the day after the the CARB demands builders go through a process that considers air quality as part of the environmental review and disclosure.
It's not bad enough that the busy bodies in Sacramento come out with more burdensome and unnecessary legislation in the name of protecting the population from the patenlty obvious in the most expensive way possible, that suddenly a question happens to appear on the topic wondering if people are worried about this?
Its not bad enough that the Califonia economy is in shambles, unemployment is at 12%, the state is spending money irresponsibly and can't balance it's books that we have bureaucrats and their sycophantic minions seeking popular support for their unnecessary and expensive rule making.
If this was REALLY a concern, a one page disclosure could be made at a cost of, oh I don't know, say ONE DOLLAR, that discloses to homeowners that choose to buy and live next to a freeway may be hazardous to their health. Oh, no but not CARB! That brain trust instead comes down with monolithic and expensive process for every home in California. A process that will further drive the costs up on the most expensive real estate in the country even higher, slowing construction and job development and moving the american dream further out of the reach of ordinary Californians.
This nonsense is why this state is broke and broken.
