Absurd Street Widths

Category: Urban Planning

Tucson: This is a residential street in central Tucson and it's wide enough to hold about 8 lanes of traffic. Why? Given that only a smattering of cars use the street, then if it were 1/2 as wide, there would be no loss in parking, the street would probably be safer due to a slower traffic flow, and more importantly - property owners would enjoy bigger front yards, you'd have vastly smaller drainage issues, the heat island effect would be reduced and the street would cost half as much to build and maintain! At the very least, the shoulders of a street like this could be redone with Gravel Pave, or a similar pourous material to address drainage issues without causing a major flash flood every time it rains.

You don't understand. Current practice REQUIRES streets to be wide enough for fire trucks to drive down them sideways simultaneously. After all, this may happen every 500 years.

Still some concerns about the structural stability and long term viability of porous pavements. As a new technology, it should be emphasized as a design solution for smaller projects that can provide a field pilot testing to identify problems.
