BACKGROUND Maintenance staff were notified of pavement settlement within Crystal Springs Park and 51 st Ave S during the week of July 18, 2016. An investigation of this issue focused on a deep surface water pipe under the settling pavement. Using video inspection, it was determined that the pipe was filled with a large quantity of material that indicated a possible failure of the pipe. Crews attempted to remove the blockage, but the removal of the material lead to additional failure of the pavement and a sinkhole. Other utilities are located within the settlement area. DISCUSSION The surface water pipe conveys water from Crystal Springs, runs continuously throughout the year, and is approximately 20 feet deep. The damaged section is approximately 290 feet in length. The pipe is located in an area with a high ground water table and visible natural water springs. As an emergency measure, the existing utilities will require stabilization, the sink hole will need to be filled with material, and a temporary pipe will need to be installed to allow the water to bypass the damaged area of the pipe until a permanent repair can be designed and constructed. An emergency Declaration in accordance with TMC 2.57.030 and RCW 35.23.352 was approved by Mayor Ekberg on July 21, 2016. A Resolution has been prepared for Council approval in support of this Declaration. FISCAL IMPACT At this time, repair costs are unknown. The extent of the needed repair can only be determined by exposing the failed surface water pipe and designing a repair. This work will be paid from the 2016 Annual Small Drainage Program funds, which currently has $525,000.00 budgeted in construction for 2016. RECOMMENDATION Council is being asked to approve the Resolution for the Crystal Springs Emergency Surface Water Repair at the 15800 block of 51St Ave. S and consider this item on the Consent Agenda at the August 1, 2016 Regular Meeting.
