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 … 

Fallen Snow is Stormwater, Too! 

As pristine white snow covers the ground, it can be easy to forget that winter snow is stormwater, too! Stormwater pollution prevention doesn't end in the wintertime! From snow storage to de-icing chemical usage, there are many winter stormwater pollution prevention tips that can keep you, your property, and out local rivers safe! 

  • While piling your snow after shoveling or plowing, chose locations where snow will be able to infiltrate when melting instead of becoming stormwater runoff.
  • Clear downspouts to ensure that melting snow from the roof does not collect around your foundation
  • Make sure storm drains near your home or business remain clear.
  • Adjust your salt and deicing product usage based on weather conditions. Before applying chemicals, consider the air temperature, sun exposure, and how much product you will need. It is very important to read the directions and time the usage of products based on conditions:
    • For Dry, Powdery Snow: Shovel or sweep snow off sidewalks and driveways immediately to prevent the need for a deicer.
    • For Wet, Heavy Snow: Apply a deicer product as soon as snow starts falling in order to prevent it from bonding.
    • For Sleet & Freezing Rain: Apply deicer product early during these conditions to prevent ice from building up.
    • For Significant Snowfall: When more than 2 inches of snow falls, plow of shovel the snow first, before using a deicing product to melt any underlying layers of snow and ice that may have built up due to packed down snow.
    • Postpone outdoor construction projects during winter months to  when you can establish new vegetation to reduce soil loss and muddy runoff. 

Mobile Contractor Education and Outreach Effectiveness Study

In 2016, cities and counties in Eastern Washington covered under the NPDES Municipal Stormwater permit were surveyed regarding types of illicit discharge complaints. It was discovered that complaints were primarily generated from four types of mobile businesses: painting contractors, carpet cleaners, concrete contractors, and food vendors. In 2010, the Wenatchee Valley took part in the "Dump Smart Program" and beginning in 2018, the a study began to evaluate the effectiveness of the Dump Smart Education and Outreach Program. The study was completed in 2019 and the final report of the study can be found here. Also available is a fact sheet summarizing the Mobile Contractor Illicit Discharge Education & Outreach Effectiveness Study, the fact sheet can be found here

Stormwater Management Manual For Eastern Washington Update
