What is Stormwater?

Stormwater runoff is the most significant source of water pollution in Oregon. When it rains, water from streets, parking lots, and roofs washes pollutants into storm drains and drainage ditches, carrying silt, oil, chemicals, trash and pesticides to creeks and welands. Many of the roads and parking lots in Clackamas County were built before requirements were put in place to manage stormwater before it enters our creeks. The polluted runoff harms aquatic life. Stormwater and the amount of pavement also contributes to flooding. When water can’t seep into the ground, creeks flood homes and roads.

What Can We Do?:

Individuals can reduce pesticide use, create rain gardens, advocate for better stormwater infrastructure and regulations on new development.. Businesses can reduce the amount of pavement and implement best practices for stormwater management during construction. Governments can implement strong rules that protect creeks and ensure that green infrastructure is prioritized and maintained.
