only if you are planning for a cars only scenario.
Frankly I am surprised at the number of people who claim to be for sustainable, walkable human scale neighborhoods, who are subscribing to this nonsense.
Riverside Planner, as you know, I like and respect you both personally and professionally, so by no means are my comments on this subject directed at you.
But this path of thinking will lead, inevitably to the destruction of the historic housing stock. It is axiomatic. You cannot sustain both a walkable neighborhood (which means that most of your daily needs and wants are within walking distances------making embedded commercial development not only necessary, but actually the very point of 'walkable) and a car storage based neighborhood at the same time.
The neighborhood was never originally designed for cars, it was designed for street cars.
It seems pretty damned obvious that the solution which allows for dense development, keeps the historic housing stock intact, lowers the overall cost of living in the neighborhood by allowing carless households is the very model that the neighborhood was designed for originally.
This 21st century demand that car storage take precedence over walkability is the very axiom that led previous generations to start the wholesale demolitions in the first place.
