Last month there was a record rainfall..... 6-10 inches in urban areas.

Perhaps these pieces of wisdom could offer some guide:

"When it rains it pours"

"Get it while the gettin' is good."

"Waste not, want not."

To me, rainwater capture can apply anywhere with a roof, a sky, and a mind to build cisterns.

California already has a massive system of rain water capture and extra-large cisterns we call reservoirs. The smaller the cistern the more expensive per gallon it is.

To me, you're rather out of touch. California depends upon the snowpack for a significant amount of its water supply -- and it ain't looking too good: http://cdec.water.ca.gov/cdecapp/snowapp/sweq.action
