Upon discovery ofthe water main lupture on December 26, 201:2,the water was shut off and the water pipe was repaired and returned to service on December 31,2012. However, the extent of the water damage to the pavement and substructure is clearly extensive and imposes risk to property, equipment, and life if not repaired as soon as possible.

Port ITEM NO- _____ZC_SD_D__ DATE or Of Seattle ~ MEETENG Februam 5, 2013 January 25, 2013 TO: Tay Yoshitani, Chief Executive Officer FROM: . Ralph Graves, Managing Director, Capital Development SUBJECT: DECLARATION OF EMERGENCY On December 26, an underground 10" diameter main waterline ruptured at Terminal 115. The water was shut off, the break__in the line was located approximately nine feet below grade and repair of the 10~inch ruptured water main was completed on December 31, 2012. - Water meters indicate the initial waterline rupture discharged roughly 13. million gallons of water, subsurface, at the terminal.' ' The paved surface in this area includes a 16" concrete-treated base with a sixinch asphalt overlay designed to support container handling equipment with 280,000 lb. axle loads. It is likely there are extensive undetected sub-surface voids caused by the rupture. It is unknown whether it is safe to operate terminal yard handling equipment at this time. As such, there is risk that a large, heavy piece of cargo handling equipment could break through the surface and fall into an undetected void. This could pose signicant risk to property, equipment, and life safety. Staff believes it is imperative to undertake an immediate and comprehensive geotechnical survey, followed by immediate repairs to areas impacted by the ruptured water main. Under'the lease agreement, the Port is responsible for maintenance and repair of the waterline and the repair of any damage caused by water line failures. The water line is repaired and in service. The extent of damage to the soil and asphalt from the water line break is clearly extensive, however since the high-pressure water migrated beneath the paved surface, areas in need of repair cannot be determined without geotechnical analysis. Until safe areas of operation are identified and repairs are completed, terminal cargo' operations are being impacted. In order to avoid possible risk to loss of property, equipment and life these repair must be undertake immediately. ' Staff intends to: . 0- Retain a. GeoTech rm to assess the extent and area of damage. a Hire a contractor to complete paving repairs prior to April 1-, 2013. I A Geo-Tech analysis needs to be completed to determine more specifically the extent of damages and repairs necessary to restore the asphalt and soil condltlons to the ' condition prior to the waterline break. A construction contractor must then complete the repairs and return the property back to the tenant by the April 1, 2013. itIS requested that the Chief Executive Ofcer make a finding that an emergency exists at Terminal 115 Northland area and authorize expedited award of service agreements and public works contracts as necessary per ROW 39.D4020, RCW 39.04280 and ROW 3980.060 to effect the emergency repairs.
