Stormwater Practices

What is stormwater runoff?

Stormwater runoff originates during precipitation events when water flows over the ground. Hard surfaces such as streets and rooftops increase runoff by preventing water from soaking into the ground. Water running over these hard surfaces can pick up sediment, chemicals, debris, and toxins which are carried to local streams. These pollutants prevent waterways from being fishable and swimmable.

What can I do to help address stormwater runoff pollution?

Always remember, with stormwater, you want to slow it down and soak it up! To help in the fight against stormwater runoff, learn about all the ways you can help here:

Rain Barrels and Cisterns Rain Gardens Bioretention Conversion from Turf to Conservation Landscaping
Downspout Disconnection Permeable Hardscapes Certified Baywise Landscaping Conversion from Hard Surface to Turf/Conservation Landscaping
