Operations and Maintenance (O&M) refers to the day-to-day operations of running the Surface Water Program, as well as long term goals for maintaining the structures of the system. In 2015 City of Kenmore authored a Operations & Maintenance Practices and Policies Manual to outline the O&M Program. The manual describes various Public Works activities as well as stormwater specific maintenance activities. The NPDES permit set forth various requirements and maintenance standards that insure protection of waterbodies.

The 5 main sections of the O&M program are:

  1. Development of Maintenance standards: The 2009 King County Surface Water Design Manual and the recent 2016 King County Surface Water Design Manual contain maintenance standards for flow control, conveyance and water quality facilities in Kenmore.

  2. Development of an inspection program: All publicly operated and maintained flow control/water quality facilities to be inspected and maintained if needed, all privately maintained flow control/water quality facilities to be inspected by the City and subsequently privately maintained, and since 2010, all catch basins inspected annually. Additionally, a spot-check inspection program to check facility integrity after large storms.

  3. Implementation of practices, policies, and procedures: developed by Kenmore to reduce the impacts associated with runoff from lands owned or maintained by Kenmore, which include streets, parking lots, roads, buildings, parks, open space, road rights-of-way, maintenance yards and stormwater facilities owned or maintained by Kenmore.

  4. Ongoing training for employees whose function may impact stormwater quality.

  5. Development of a Stormwater Pollution Prevention Plan (SWPPP) for all heavy equipment maintenance or material storage facilities owned, operated, or shared by Kenmore.

In Kenmore there are more than 200 facilities that the City is responsible for inspecting and maintaining, and the number grows every year. Each one is carefully inspected by the Surface Water Technician, and when it needs maintenance the work is routed to the appropriate contractor.

In addition to publicly maintained facilities, there are over 100 privately maintained facilities. The Surface Water Technician also inspects these facilities, but the maintenance responsibility is private.
