As a real estate agent, I have become interested in planning and urban development. There are a number of interesting issues. Many americans actually do prefer suburban car life and that is fine, but for those who would prefer to be able to walk a lot more, there are a number of problems. Many cities saw urban flight which abandoned the cities and made them places most people would not live by choice. Nos that the trend is back to certain urban centers, only the wealthy can afford to buy in the decent urban areas. I see it every day. Peopel call me up and say they want to be in an n city walkable neighborhood and I have to tell them they can not afford it, not even a condo. Most new development in the us does not really support it. Vancouver built a whole new huge neighborhood. They gave the developer a sweet deal on the condition that they put in a rail lines and no dwelling unit could be any further than four blocks from a stop. But in the Us, they think by building a condo with a coffee shop and tanning salon and a gap in the bottom is somehow going to revive the urban eneighborhood. Where are the green grocers, where are the grocery stores , and hardware stores, things people need. Some suburban communities are building shopping centers in walkable neighborhoods out in the burbs, but people still have to drive to work and there is no public transportation, except maybe buses which are slow and limited. Seattle put in a light rail line recentlyt which will open soon. It is good and a lot of density has sprung up along the line. But it is one line and costs a fortune. I miss the heck out of San Francisco. Tight dense neighborhoods with business districts, bu and light rail lines.
