  • Wash water from car washing activities typically contains dirt (sediment), soap (detergent/surfactants), gasoline and motor oil, as well as metals and oil/grease residues from exhaust fumes and brake pads. When this dirty water is allowed to flow into storm drains, it travels directly to our local creeks and rivers without treatment. This pollution can kill […]

  • There are numerous environmental  benefits to trees in urban settings. These include the capture of carbon dioxide by trees, shading, and habitat for wildlife. Urban forests can also act as natural storm water management areas by filtering particulate matter (pollutants, some nutrients, and sediment), by absorption of water and by facilitating evapotranspiration to reduce runoff.

  • What’s on the land determines the condition of the creeks and water quality. Before we developed our urban landscape and farms, the Tualatin River Watershed was covered with forests, prairies and wetlands.  When the rain fell, it was intercepted by plants or soaked into the ground.  There was very little runoff from the ground. Impervious […]
