Stormwater Management

What is Stormwater?

Stormwater runoff is water from rain or melting snow that "runs off" across the land instead of seeping into the ground. Generally speaking, stormwater is rain that washes off driveways, parking lots, roads, yards, rooftops, and other hard surfaces. Stormwater runoff is a concern, as it can pollute lakes and streams. Together, the City of Lynden and its residents need to take an active role in keeping our stormwater clean.

What Is the City Doing to Clean up Stormwater?

Lynden's population has grown and we are now required to develop a Stormwater Management Program. This Stormwater Management Program details how we plan to comply with the terms and conditions of our National Discharge Elimination System (NPDES) Phase II Permit.

In 2013 the Environmental Protection Agency (EPA) and the Washington State Department of Ecology (DOE) identified Lynden, based on size and location, as one of thousands of municipalities in the U.S. requiring an NPDES stormwater permit. Lynden is required to maintain its municipal drainage system, which flows into waters of the United States.

The Lynden Public Works Department provides environmentally sound, efficient and effective management of the City's storm drainage system. This system is comprised of catch basins, curbs, gutters, ditches, man-made channels, pipes, culverts and storm drains. Most of what comes into City storm drains eventually flows into Fishtrap Creek and ultimately into the Nooksack River, both of which are considered waters of the United States.

The City of Lynden's Stormwater Program includes the Following Elements:

  • Stormwater Management Program Development
  • Stormwater Planning
  • Public Education and Outreach
  • Public Involvement and Participation Component
  • Stormwater System (MS4) Mapping and Documentation
  • Illicit Discharge Detection and Elimination
  • Controlling Runoff from New Development, Redevelopment, and Construction Sites
  • Operation and Maintenance for Municipal Operations
  • Source Control Program for Existing Development
  • Water Quality Monitoring of Stormwater and Fishtrap Creek
  • Water Quality Monitoring for Nooksack River Total Maximum Daily Load Requirements

What Can You Do for Clean Water?

We can all have a part in preserving and improving the quality of water in our local waterways. Stormwater that runs off properties and into streets travels down storm drains directly to the nearest stream, wetland, lake or pond. The City works to ensure that all waterways remain clean and comply with the Clean Water Act and you can help.
