  • Increase the watershed's ability to store water
  • Preserve and restore native plant and wildlife communities
  • Protect and preserve groundwater quality and quantity

Eligible projects

Selecting the right project is important to ensure that it is effective at reducing stormwater runoff and pollutants. Below are some examples of eligible projects.

  • Rain gardens
  • Permeable pavement
  • Green roofs
  • Tree planting
  • Rain barrels
  • Other innovative stormwater management practices

Descriptions of the eligible projects can be found on the eligible projects page
