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 starts as rain and snow/ice melt. Stormwater can soak into the soil (infiltrate), can stay on the surface toevaporate, or runoff and end up in nearby streams, rivers, or other water bodies (surface water).
Stormwater Pollution is when rain water 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 >>
Stormwater Code and Manual Errata- As of January 8, 2016, Clark County will use the approved Clark County Stormwater Manual 2015 to comply with stormwater regulations. An errata was approved on November 22, 2016 by the BOCC. These codes and manual are deemed to comply with the Department of Ecology Phase I Municipal Stormwater Permit. More >>
Water Protection Tip for the Month - Check for car leaks! If you park your car outside this spring, check the pavement when you pull out of your driveway or parking spot and see if there are fluid leaks (e.g. rainbow effect in the rain, dark oil patch, bright green fluid, etc.). You can get a FREE vehicle leak check at any AAA auto shop in Clark County through the Don't Drip and Drive program (even if you are not an AAA member). More >>>
