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.

Water Protection Tip for the Month - Clean up your summer yard! With all of this sunshine, your yard is requiring lots of maintenance. Make sure to keep yard debris in the compost bin and do not sweep materials into the street. When power washing, direct water to a landscape area to soak into the ground or filter the water to keep debris out of nearby stormdrains. Do your part to prevent storm water pollution. More >>
