No more housing is needed. In public housing, upgrading is definitely needed, and I support that. I do not support increasing density by tripling it such as in Rebuild Potrero. I don't know whether the other housing projects are increasing the density by so much, but they should not be. Increasing density in our limited space increases social tensions, strains city services (for which we are ill equipped to pay) and increases traffic to undesirable levels. Cut back on this density increase now. That will avoid further strain on city services, avoid increasing social tensions and allow more positive interaction between neighbors and neighborhoods, and keep traffic from increasing.
