This
represents a fundamental change in the priorities for urban infrastructure,
although it continues to encompass the early-20th Century urban goals of
enhancing the health, safety and welfare of humans. As researchers have learned
more about urban ecology, we have recognized that human health is intimately
connected to the health of other species in a region. Similarly, the safety
and welfare of humans is dependent on the sustainability of our built environment.
Together, these insights have led to an increasing focus in urban design
on building “sustainable infrastructure,”
which must make sense in terms of its long-term social and environmental
costs as well as in its short-term capital costs. |
