From the San Francisco Chronicle:
The state's budget gap requires painful cuts. The tough choices ahead require us to take a hard look at which programs achieve their goals and which do not before making decisions that will affect the lives of all Californians....

Some are in urban downtowns and others are rural, and each has a different mix of manufacturing, office space and retail.

These include zones where more effort was placed on marketing and outreach and those where there is less manufacturing.
