Which is a problem in and of itself, at least theoretically. I don't live in SF, but I do live in a highly balkanized area (Atlanta) where the proliferation of local governments is a weight around the neck of the region overall

There are a couple of metro areas that escaped this problem by having regional government, Mpls/St Paul, MN and Portland, OR.

Minnesota has the Metropolitan Council which derives its power from state statute and can supersede the decisions of local governments. The same people that bitch about ‘my tax dollars’ complain about the Met Council but I feel it provides a cohesive regional planing organization and they provide water, sewer, transportation, and regional parks. https://en.wikipedia.org/wiki/Metropolitan_Council_(Minnesot...

Portland, Oregon has a similar organization called Metro that I am not familiar with, other than it is similar to the Metropolitan Council. https://en.wikipedia.org/wiki/Metro_(Oregon_regional_governm...
