I'm on the transportation group, but I'm going to be presumptuous and initiate the policy discussion anyway.
I think of "policies" as the official (as well as the totally unofficial) "rules" that determine how we all live our lives -- and thus, how much GHG (greenhouse gas) emissions we are cause. A first step, of course, is to realize that these policies even exist.
For example, our "streets" (by which I mean the total right-of way, not just the vehicle travel lanes) tend to be "managed" to favor people-in-vehicles over people-on-foot (or bike). (If you have any doubts, go to the intersection of Volker Boulevard and Brookside Boulevard.) The result is that streets are hostile to non-motorized people, and thus people (at least those who have a choice) choose to drive without even thinking about it.
I'd like this "Policies We Might Change" topic to invite lots of thoughts about how the official (and unofficial) "rules" shape our individual and collective lives, and about what we might like to change.
So here's a suggested "policy change:" Let's decide we're going to make the heart of the city (if not the entire city) a "Feet First District" within which accommodations for walkers and cyclists -- and their need for mobility and safety and security -- will be paramount.
