Dense construction with high-quality public transport is a significantly more environmentally-friendly city design than a sea of single-family homes with mandatory car ownership. The latter may be more superficially "natural" - green swaths of suburbia vs. concrete jungles - but it really is only superficial.
> San Jose style growth
San Jose, like the entire Bay Area, is crippled by the exact same rampant NIMBYism and suburban sprawl as Santa Cruz. Not only would a densely constructed San Jose be more environmentally friendly, its economic growth would be _significantly_ higher.
Underneath all the posturing about the environment and "the feel of the community", the only thing NIMBYism protects is high property values and rents.

> natives who resent 5 story huge San Jose style apartment blocks going up in their beautiful city
I'm sorry, _what_? In what universe is a 5 story apartment building huge or unreasonable in one of the most desirable areas to live in the country?
