Fifth - i dont mean to argue with you, it is just something im passionate about.
Sprawl is costing the govt and by extension all of us an enormous amount. money that could be used on much more productive things.

"This study would
suggest that if a city has land that can be redeveloped
then there will be highly significant infrastructure
cost savings associated with this compared to new
development on the urban fringe.
Once established, there are many ongoing operational
costs of both urban typologies but the most significant
operational costs are associated with transport. Private
and public costs are needed to ensure people travel
more easily to and from these urban areas.
The cost
of both on private and public transport operations
for greenfield development is around $18,000
per household per year more than that for urban
redevelopment. This needs to feed into debates about
aff ordability as over a 50-year period this adds up to
a difference of $251 million for 1000 dwellings, or
$251,000 per household. A number of US studies
are now showing that transport costs on the urban
fringe are higher than mortgage costs (CTCNT, 2006;
Lipman, 2006).
