The sinkhole is in the middle of a driveway that serves two properties. The drain line creating the sink hole has been inspected. The findings show the concrete pipe has broken allowing water to escape its intended path and significantly reducing the capacity of the pipe. This leads to water both backing up to the inlet and escaping out into the driveway surface. Parks is proposing to replace the broken 12-inch concrete drainpipe with a corrugated HDPE pipe and to add a type 1 catch basin to facilitate a proper connection where the drain changes directions. Parks also proposes to add a type 2 catch basin where the culvert from under the trail connects to the new HDPE pipe. No in-water work will occur, and no critical areas will be impacted by the project. This project is repair and maintenance and does not change drainage patterns or stormwater discharge locations. SEPA Exemption King County has determined that this project is categorically exempt from the State Environmental Policy Act (SEPA) under WAC 197-11-800(3) Repair, remodeling, and maintenance activities.
