Pebble Beach: overpumping the Carmel River and Seaside aquifer. The entire Monterey Peninsula has been under Stage 1 water rationing since 1999, which so far basically means new development permits are almost impossible to get. The State Water Control Board has ordered reductions in that overpumping by 2014, and so locals are scrambling to build a desalination plant in either Marina or Moss Landing.

Pasatiempo/Santa Cruz: Same thing, overpumping the local watershed and aquifers. They too have probably overshot their carrying capacity and will need to turn to desal.
