Chicagos Water Agenda

• Understanding that our water resources work as a
  complex and connected system, the agenda calls
  for a comprehensive approach to the Citys
  treasured waterways to ensure that they are
  conserved for future generations, protected and
  improved, and managed so that water can continue
  to sustain us, connect us as neighbors, and
  define our communitys role nationally and
  internationally.

Chicagos Water Agenda

• The City will continue to invest in and
  encourage green infrastructure and design in City
  projects as well as private development.
