  • Surface Water Management - Stormwater

Surface Water Management (Stormwater)

Utility Fees

Streams and greenspaces are some of Tigard’s most beloved spaces. Creeks fed by springs and rainwater help define neighborhoods, provide pristine views and offer quiet places to experience nature.

The Public Works Department protects local environmental quality in many ways, including the Surface Water Management (SWM) Program. As a part of the SWM Program, the stormwater system collects, moves, and treats stormwater—or rain and snowmelt—before releasing it into local waterways.

Current State
In 2018 the City Council adopted a Stormwater Master Plan to protect the community from the negative effects of urban stormwater runoff such as:

  • Erosion
  • Flooding
  • Water Quality

This was the first update in 30 years. As such, there are built-up needs. The plan provides several recommendations for programs and projects to address stormwater management.

  • Recommended Top Capital Improvement Projects
  • Recommended Programs

How the Fee Benefits our Community
The program pays for the following:

  • Maintenance and construction of the drainage system including stormwater detention areas and water quality facilities.
  • Street sweeping for curbed public streets and catch basin cleaning.
  • 24-Hour emergency flood response and repair.
  • Water quality monitoring in the Tualatin River and its tributaries.
  • Water quality investigation and spill response.
  • Enforcement of erosion control and water quality facility requirements.
  • Enforcement of buffer zones between new development and creeks and wetlands.
  • Coordinated planning and design of regional water quality and flood management projects.
  • Long-term Watershed Planning.
  • Public outreach and partnerships for pollution prevention and education.

Fee Update
The city reviewed several options to restructure funding to support the Stormwater Master Plan and ensure the system is working effectively. Based on a recently completed Stormwater Rate Study, City Council voted to increase the fee by $3.50 per month, effective July 1, 2020. The last time that rates increased was in 2008.

  • Current Surcharge: $2.00/month per ESU
    $850,000 average annual revenue
  • Adopted Surcharge: $5.50/month per ESU, effective July 1, 2020
    Approximately $2,400,000 over the 4-year rate setting window

Current Fees
A fixed charge and a surcharge, included on your utility bill, fund services provided to the Tigard community.

Fixed Charge

  • The fixed charge funds the day-to-day maintenance and operation of the system.  
  • The fixed charge is set by Clean Water Services (CWS) and billed by the City of Tigard.
  • The city retains 75% of the fixed charge and CWS receives 25%.
  • The fixed charge is currently $9.25 per Equivalent Service Unit (ESU)* per month.

Surcharge – Local Service Fee

  • The surcharge funds the repair and replacement of Tigard Stormwater infrastructure.
  • The surcharge rate is set and billed by the City of Tigard.
  • The City retains 100% of the surcharge.
  • The surcharge was set in 2007, and adjusted in 2009, to supplement the fixed charge.
  • The surcharge was set at and currently is $2 a month per ESU*.
*An ESU is the size of the impervious surface area (such as pavement or rooftops) on a property. Single family residences are generally counted as one service unit, and commercial properties are billed based on a measurement of impervious surface area. One ESU equals 2,640 square feet of impervious surface.
