Stormwater Management in Clark County
As residents of the rainy Pacific Northwest, we might assume that clean, fresh water in our streams and rivers will always be ours for the asking. But pollution, urbanization and other population pressures challenge this assumption.
Clark County administers the Clean Water Division to safeguard the quality of our streams, rivers and lakes and comply with the federal Clean Water Act and state regulations. The program's primary activities include stormwater capital improvements, water quality monitoring, public education and outreach, regulations and enforcement and stormwater maintenance. As the county's population continues to increase, the Clean Water Division is committed to keeping our waterways clean for people, fish and wildlife. Click here for an overview of our program.
Stormwater is water that originates during precipitation events and snow/ice melt. Stormwater can soak into the soil (infiltrate), be held on the surface and evaporate, or runoff and end up in nearby streams, rivers, or other water bodies (surface water).
Stormwater Pollution is when rainwater washes across hard surfaces picking up dirt, debris, oils, and other materials that get into the stormwater and wash into drains to lead to creeks, streams and rivers.
New Tree Planting Program - We are partnering with Friends of Trees to plant 500 street trees in the next three years in the North Salmon Creek, Felida and West Hazel Dell neighborhoods. A grant from the Lower Columbia Fish Recovery Board will allow neighbors to purchase low cost trees and have help planting them at neighborhood planting events. Volunteers are needed for this fun and important project. Planting trees protects our local waterways. More >>

Water Protection Tip for the Month - Keep drains clear - do not sweep leaves into streets! With rain and leaves falling all around, do your part to keep storm drains in your neighborhood clear to prevent flooding. Rake leaves from your yard and compost in the appropriate compost bin or your yard bin. If you have a drain on your street, help sweep it clear and let your neighbors know they can help. Prevent flooding.....do your part to prevent storm water flooding and pollution.
