  • Rain Gardens
    Create a rain garden on your property to capture storm water runoff from rooftops, driveways, walkways, and compacted lawns.  Otherwise when it rains excess water when it rains will discharge, without any treatment, directly to local waterways through the stormdrain system. This stormwater runoff becomes polluted with contaminants such as oil, grease, excess fertilizer, pesticides, grass clippings, and pet waste.  Download the Rutgers Rain Garden Manual free of charge to help you learn more about how to create a rain garden on your property.
