it blocked whole blocks as uses, so a whole block was either slr, sli, rsd, but what our new map is is a finer grain. it acknowledges a variety of uses, sort of preserves them, and likes to mix it up. in it is no longer its theoretical goal. it is actually one that sort of acknowledges the uses and tries to let them exist and to mix it up. we started with the alleys. there is little ability we had in the district called the residential enclave district. it had to have 75% of all the buildings residential. we had eight or nine of them existing in western soma. but this is the reality of the other part of our alley. so we now have an r.e.d. mix that is basically to enhance and preserve all those warehouse buildings that used to be the plumbers, electricians, and the people living upstairs. now their offices, consultants, businesses, and there are printers. but we want to preserve those uses. we do not want to turn our commercial alleys and the back doors for folsom st. or howard. we want them to have their own life, their own viability. they should not be the driveways for the big alleys
