Tree Planting

Trees Support Water Quality

Pierce County receives 38-56 inches of rain per year. Rain that does not soak into the ground turns into runoff that picks up oils, fertilizers and other chemicals along the way that pollute our streams, rivers and Puget Sound.

Trees catch rainwater and slow runoff, which cleans the water and reduces the risk of flooding. They help prevent erosion along stream banks and allow more water to soak into the ground to replenish groundwater.
