was also found to have extensive sedimentation problems from stream bank erosion and the occasional catastrophic failure of tailing slopes that remain from the old coal mining activities in the creek's headwaters and landslides of the steep slopes above the creek. Since 1997, the City of
Bellevue has maintained two sediment retention ponds in the system, one immediately upstream of Interstate Highway 405 and another immediately upstream of Coal Creek Parkway. While the sediment ponds are helping to control excessive delta formation through the reduction of large particles, smaller particles and fine silts and clays remain suspended and wash downstream (Tetra Tech/KCM, 2005). Thus the ponds provide no protection for spawning and rearing habitat (Kerwin, 2001).

The contract work will consist of the design of closures, development of construction specifications, and estimation of closure costs. OSM plans to begin construction on the first group of closures in the summer of 1986.

Basin-wide sampling took place in 2007, including four sites along the Coal Creek reach. Concentrations of arsenic at sites A442 and D442 exceeded the
Sediment Cleanup Objective (SCO), meaning effects to sediment-dwelling animals are possible, but uncertain. At site A442, concentrations of nickel and

A comprehensive basin plan for Coal Creek was produced by King County and the City of
Bellevue in 1987 (King County). As part of this planning effort a hydrologic model was developed. It was found that base flows in Coal Creek are augmented by approximately 10% by flows from mine tunnels. Coal Creek

Work associated with the inventory also included the immediate erectioh of temporary fences around 16 of the worst hazards until more permanent closures could be designed. OSM has contracted for engineering services to develop closure designs for the priority 1 hazards. The contractor is Skelly and

At least 19 mines have been operated in the area (Walsh, 1983) and extensive areas are still known to contain open mine workings. OSM reclaimed entries to the old
Newcastle mine in 1983 and will fence off 16 extremely hazardous openings in the fall of 1984. OSM has budgeted $ 80,000 for this
