Rain that falls on our roofs, driveways and other hard surfaces can carry pollutants to our rivers and streams. During big storms, a large volume of rainwater can flood homes, cause sewer overflows, and erode hillsides and stream banks. There are some easy and economical ways that we can all help to reduce the volume of stormwater runoff from our properties with green infrastructure projects that are useful and attractive additions to our properties.
The Rainways Engineer's/Planner's Tools provide ways to explore and understand the efficacy of green infrastructure projects on stormwater runoff and combined sewer outfall reduction.
