Clackamas County Water Environment Services Action Planning & Geomorphic Monitoring

wes2 RCClient: Clackamas County, Water Environment Services

Since 2009, Waterways staff has worked with Clackamas County’s Water Environment Services (WES) on Action Planning and Geomorphic Monitoring efforts in the more urbanized portions of Clackamas County. In 2008 and 2009, Waterways was an integral member of a team of consultants that prepared Watershed Action Plans (WAP) for the Kellogg/Mt. Scott and Rock Creek watersheds. Waterways prepared the hydrologic and geomorphic sections of the Action Plan for each basin and assisted in the development of a subwatershed-scale risk assessment, identification of project priorities, and a tool-based identification of levels of service.

In 2009 and 2010, Waterways teamed with ABR, to establish long-term geomorphic monitoring stations throughout WES’ Service District #1 and SWMACC District. The monitoring effort was initiated in response to recommendations in the WAP’s for the Kellogg/Mt. Scott and Rock Creek to better understand the current health of streams within the district and provide long-term monitoring data to evaluate the success of actions and projects that seek to improve watershed health.

In 2013 Waterways was hired by WES to evaluate the feasibility of implementing restoration actions on six reaches identified as “At Risk” during the 2011 geomorphic monitoring work. Waterways collected detailed site information in each of the study reaches, identified a range of potential restoration alternatives, and prepared preliminary cost estimates for design, permitting, and construction. The results were summarized in a technical memorandum that WES is using to discuss the potential projects with stakeholders and obtain grant funding.
