@sama - since so many people here are in The Bay Area, i&#x27;ll give the obvious answer for the region -- <i></i>high density housing.<i></i>  I&#x27;m from NYC and we support a lot more housing in a much smaller area.  This is accomplished by stacking upwards towards the sky.  I appreciate there are earthquake concerns, but I also understand that many of the barriers for high density housing are political and social.<p>I&#x27;ll bet many problems in the Bay Area would be resolved with high density housing.  A selfish list: shorter commutes (--&gt; more time with family), lower rents (--&gt; more people willing to move here --&gt; fewer developer &quot;shortages&quot;), less cars on the road, less pollution.
