The Surface Water Management Agency of Clackamas County (SWMACC) provides surface water mangement services to the City of Rivergrove and portions of unincorportated Clackamas County draining into the Tualatin River. SWMACC was created to address the Oregon Department of Environmental Quality (DEQ) regulations applied to the Tualatin River as a result of the topography of the basin and density of development. 

SWMACC Watershed Action Plans were completed in July 2010. The Action Plans were focused on characterizing current conditions within the District and determining the desired levels of service of SWMACC Customers. To view the characterization report click on the links below.

Online Survey Results - In order to determine the desired levels of surface water management services our SWMACC customers want, we conducted an online survey to get opinions about protecting the Lower Tualatin River from pollution caused by surface water runoff. The survey asked customers questions about the current services we provide and the potential to provide additional services if desired. We also asked customers to provide us feedback on whether or not they would be willing to pay for any additional services they would like to see. Please go to this survey link to view the results. We are listening.
