SDAO Membership Information
Special Districts Association of Oregon (SDAO) was formed in 1979 to give special districts a stronger and united voice at the Oregon Legislature. As with similar associations that support cities, counties, schools, and local governments, the Association provides advocacy with state administrative agencies and other units of government, training, information resources, and other support programs. SDAO has grown its membership to over 900 local government members. To the left, you will see a graphic representation of our membership profile.

To learn more about membership with SDAO, please view our membership guide.

What is a Special District?
Special districts are a form of local government. They are created by their constituents to meet specific service needs for their communities. Most perform a single function such as water delivery, fire protection, wastewater or cemetery maintenance, to name a few. Some, like county service districts, provide multiple services. Learn more...
