City of Tigard

Stormwater Master Plan

A unique feature of Tigard is our many open and natural creek greenways which include Fanno, Summer, Ash, and Red Rock Creeks. These watery greenspaces help define our city’s identity. The creeks are fed by springs and rainwater.  Development nearby and uphill of the streams affects our streams, often in negative ways.

When it rains, stormwater washes over streets, roofs, lawns and parking lots picking up oil, sediment, bacteria, grease and chemicals that can pollute our creeks and the Tualatin River. Pavement, including streets, sidewalks, roofs and parking lots, causes rain to runoff quickly into storm pipes and creeks. This fast, flashy stormwater runoff can cause erosion of stream channels and local flooding. The City of Tigard is launching an effort to plan for policies and actions that protect people and the environment from the negative effects of urban stormwater runoff. 

Master Planning Effort
Starting in June 2016, the city will be working with residents, business owners and a consultant team to look for ways the city can protect people and property from flood events, manage the stormwater pipe system, enhance streams and floodplains, and more. There are likely to be more needs than funds for projects, so we will also be developing priorities and policies to direct us in solving the most important problems first.

The city partners with other agencies in planning for stormwater runoff.  In cooperation with Clean Water Services, Tigard works to enhance the public drainage and creek systems to meet public needs and to comply with strict water quality regulations set for the Tualatin River and its tributary streams by the Oregon Department of Environmental Quality (DEQ).

Public Involvement
We want to create a plan that reflects community values and has community support.

We need your help to understand:

  • What about our creeks and river are most important to you?
  • What flooding, erosion or pollution problems have you observed?
  • What and where should be the city’s priorities for projects and maintenance?
  • What type of investment should the city be making over time?

We encourage you to become involved and part of the decision-making process. There will be a variety of public involvement opportunities available to the community. This includes a series of community open houses throughout the process, information on our website, as well as a stakeholder committee.

A good way to stay informed throughout the planning process is to sign up for the project’s email notices for meetings, milestones and input opportunities.
