What We Do

The City of Arlington Stormwater Utility provides our customers with reliable, quality service that protects public health, natural resources and receiving waters. The utility works with landowners and city staff to assure our surface waters meet or exceed local, state and federal water quality standards. We are fortunate in that our streams traveling through town continue to have coho salmon and cutthroat trout spawning and living out their various life stages. Many of us also enjoy swimming in the Stillaguamish River on a hot summer day. Through the proper management of stormwater this activity should continue on for generations.

The Source of Stormwater and Its Destination

Stormwater is surface water generally associated with rain fall that flows into and through the City’s drainage systems. There is no single system, but rather multiple systems with nearly 3,500 catch basins and 48 miles of conveyance lines. Included in our systems are natural stream channels, culverts, ditches, detention ponds, wetlands and infiltration systems.


The natural streams that run through Arlington include:

  • Eagle Creek
  • Edgcomb creek a tributary to Quilceda Creek and the Snohomish Estuary
  • Kruger Creek
  • March Creek
  • Portage Creek
  • Prairie Creek

We contribute surface and groundwater to these natural systems and share the watersheds with animals, birds, and fish. A majority of Arlington’s drinking water comes from wells which are fed from surface waters that have infiltrated from locations upstream and around Arlington.


In accordance with our National Pollution Discharge Elimination System (NPDES) Phase II permit issued by Department of Ecology we provide the 24-hour spill hotline, 360-403-4600. If you see discharges or spills such as paint, oil, fuel, muddy water or strange odors leave a message on the hotline and we will investigate.
