Potential Loss of Arable Land in the Central San Joaquin Valley, CA

Submitted by dylan on Mon, 2009-08-17 15:19.

Rapid urban and sub-urban expansion in the San Joaquin Valley have resulted in the loss of millions of acres of prime farmland in the last 100 years. Approximately 11% of class 1 (irrigated) land and 7% of class 2 land have already been paved over in the Fresno-Madera region (first image below). Recent projections in the expansion of urban areas in this region suggests that by 2085 an additional 28% of class 1 and 25% of class 2 land will be paved over (second image below). This is a preliminary summary-- details to follow.

This takes into account SB

This takes into account SB 375 changes in projected development? SB 375 was signed last September - just asking...

SB 375

Good question. I'll look into that, and post back with the details. Just in case, here is some more information on SB 375.
