There was an interesting article in today's Times Press Recorder about the water situation for the 5 cities. The article is here: http://www.timespressrecorder.com/articles/2005/04/27/news/news01.txt

What's missing is a chart they included along with the article which I thought had some good info in it about buildout timeframes. Here is some of what it included.

Oceano- current population7260, buildout population (est. 2033) 15,787
Pismo Beach - current population 8551, buildout (est. 2025) 11,122
Grover Beach - current population 13,067, buildout (est. 2018) 16,000
Arroyo Grande - current population 15,851, buildout (est. 2023) 20,000
