New Tools to Manage Stormwater—Without Structures
Nonstructural measures to manage stormwater quality and
volume—physical, regulatory, or educational—are becoming increasingly common in
the United States, Australia, and New Zealand. In a recent study, researchers
Andre Taylor and Tim Fletcher identified four nonstructural tools that have the
greatest potential value for stormwater-management agencies. The authors also
present an evaluation framework to assess the performance of these methods.
The researchers define nonstructural stormwater-quality
management tools as “[i]nstitutional and pollution-prevention practices
designed to prevent or minimize stormwater pollution and/or reduce the volume
of stormwater requiring management. They do not involve fixed, permanent facilities,
and they usually work by changing behavior through government regulation,
persuasion, or economic instruments.”
