Welcome to the Green Values® Stormwater Toolbox

  • Learn what green infrastructure is and does.
  • Learn how the use of green infrastructure saves money.
  • Understand the costs and benefits of using green infrastructure to mitigate the need for different types of built water infrastructure, such as sewers and detention basins.
  • Search our comprehensive bibliography for more information.

The Green Values® Stormwater Toolbox was originally developed primarily for use by planners, engineers and other municipal staff. As a result, we’ve tried to err on the side of giving too much technical information. However, we recognize that individuals are also interested in the benefits of green infrastructure, both for individual sites and to influence public policy.
