Santa Cruz gets enough rain to sustain itself. However, adding a new reservoir was stopped in the 80s. The area is beautiful, but the same people who preserved a lot of what is special about the place also put policies in place that are destroying it. It's a lack of balance.
Sadly local municipalities can't control the decisions that a given UC makes. UCSC should have had enrollment capped at a sustainable level -- water, housing and traffic. Adding more in upper campus, eh, there is really still only one way in -- no eastern access, etc.
I understand the benefit of exposure to environmental and socially conscious issues, but reality should factor into planning and that should be a lesson as well.
