Wenatchee Valley Stormwater Management Program

Wenatchee Valley Stormwater Program LogoThe Wenatchee Valley Stormwater Technical Advisory Committee (WVSTAC) was formed in January 2004 through a memorandum of understanding between Chelan County, Douglas County, the City of East Wenatchee and the City of Wenatchee. The goal of this committee is to develop a regional stormwater program and meet the requirements of the Eastern Washington Phase II Municipal Stormwater Permit.

What's happening now … 

Fall leaves are here! Is your nearby storm drain ready?

The crisp air of fall and changing leaves are finally here, and though we may love the colors, we do not love the clogs! As falling leaves cover our yards and business parking lots, many residents and businesses blow or sweep fallen leaves into the street and throughout parking lots, not realizing they become a safety hazard to both their property and the neighborhood. It is important to remember that leaves blown or raked into the street can become blockages in public and private storm drains. Storm drains are meant to capture, move, and release rainwater into nearby water bodies. If leaves are blocking storm drains, neighborhood flooding is more likely!

To prevent neighborhood flooding:

  • Rake your leaves into a pile and collect them into a yard waste bin or bag
  • Use leaves as mulch on garden beds or landscaped areas- Mulched leaves provide a nitrogen rich fertilizer for lawns and gardens.
  • Turn leaves into compost- Leaf compost provides a dark, rich, earthy organic matter layer to garden soil that will add nutrients. Compost retains moisture and repels weeds!
  • Use a broom, rake, or blower to clear leaves from storm drains near your business or property
  • Share with your friends and neighbors how they can help protect their property from flooding.

Throughout the Wenatchee Valley, there are thousands of storm drains and billions of leaves that will fall and City and County crews work hard to keep the streets clear, they need your help! Keeping drains in the street and on private property clear before and during storms, helps prevent flooding and keeps your property safe!
