Green Infrastructure

When rain falls on impervious surfaces (i.e. roofs, streets, parking lots, sidewalks, etc.) the water cannot soak into the ground as it naturally should. This stormwater drains through gutters and storm drains and is discharged into nearby water bodies. Stormwater carries trash, bacteria, heavy metals and many other pollutants. Stormwater also has the potential to cause erosion and flooding that can damage habitat, property and infrastructure.

Green infrastructure reduces and treats stormwater by protecting, restoring and mimicking the natural flow of water through a range of measures, including those that use:

  • Plant or soil systems
  • Permeable pavement, surfaces or substrates
  • Stormwater harvest and reuse
  • Landscaping

Green infrastructure also provides habitat for wildlife, flood protection, and cleaner air and water.

Log Your Environmental Efforts

Residents can help the County track environmental data—including where individuals plant trees or install rain barrels—that is used to inform potential mitigation methods and for mandatory reporting. Please take a moment to log your environmental efforts in the Environmental Reporter tool.
