Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, parking lots, and streets, prevent stormwater from naturally soaking into the ground. Unless properly managed, increased stormwater runoff can create flooding, erosion, and water quality problems. Water quality problems can include:

  • Polluted water supplies
  • Loss of native vegetation or habitat
  • Loss of aquatic species of fish and other wildlife
  • Loss of safe recreational areas

As property development increases, the amount of rainwater soaking into the ground is reduced, creating more stormwater runoff entering the City’s drainage lines. The City works hard to prevent stormwater flooding and pollution, and is actively addressing problems in community areas. View the stormwater projects page for more information.

The City of Jacksonville Adopt-A-Program is a City effort and an organized way to help clean up your local community. Learn more about how you can Adopt-A-Stream in your neighborhood or local area.
