"Buildings have a substantial impact on the health and wellbeing of people and the planet. Buildings use resources, generate waste and are costly to maintain and operate. Green building is the practice of designing, constructing and operating buildings to maximize occupant health and productivity, use fewer resources, reduce waste and negative environmental impacts, and decrease life cycle costs." -USGBC

Seattle Public Utilities

"Rain falling on our roofs, driveways, or compacted soil rushes off quickly to the nearest drain or stream. In big storms, this excess “storm water” can cause sewer backups, or pollute and erode our streams and waterways." -Seattle Public Utilities

King County

"With every storm, rain carries pollutants off our roofs, driveways and other hard surfaces to local creeks, Lake Washington and the Puget Sound. During big storms, the sheer volume of this “stormwater” can cause sewer overflows, and erode hillsides and stream banks. Rain gardens and cisterns can help control this stormwater with your help." -King County

700 Million Gallons

"As rain runs off streets, rooftops, and parking lots, it picks up oil, grease, metals, and other pollutants, carrying them to our lakes, creeks, the Duwamish River, and the Puget Sound. In many parts of Seattle, rain also flows into the sewer system. During storms, this rain can cause sewage overflows into local waterways. Recent scientific studies have determined that polluted runoff is the biggest threat to water quality in the Puget Sound." -700 Million Gallons
