Water that falls during a rainstorm or comes from melting snow is stormwater. Kirkland has many hard surfaces like roads, parking lots, rooftops, and driveways. These are called impervious surfaces and do not allow this water to soak into the ground. Water that falls on these surfaces becomes stormwater runoff.
Stormwater runoff picks up pollutants like oil, chemicals, fertilizer, pet waste, and soap. It carries these pollutants to the nearest storm drain. In Kirkland, all storm drains lead to the nearest creek, wetland, or Lake Washington. Stormwater runoff is not cleaned or filtered before it reaches our waterways. It can damage habitat and water quality.

Stormwater runoff runs off developed land during the rainy season. As a result, this water can flood homes, businesses, and roads. Stormwater can also flood and damage creeks and wetlands needed for fish and other wildlife habitat.
