BACKGROUND The City has been implementing a phased rehabilitation of the sanitary sewer system in the Commercial Business District (CBD) since 2013. The sewer lines were originally installed in the 1960's and have served their effective lifespan. Rehabilitation or replacement is necessary to extend the service life of the sewer system. Visual inspections have revealed that certain segments of the sewer main have deteriorated severely and multiple failures have occurred (see attached photo). The sewer mains must be cleaned of debris before they can be slip -lined and the process of high - pressure water cleaning can damage the sewer or even remove bedding adjacent to the sewer mains if a breach has already occurred. Some sewer mains have not been visually inspected due to inaccessibility of the inspection camera; therefore, some pipe conditions are unknown. DISCUSSION Slip- lining began in late January 2016 with initial efforts proceeding without incident. The contractor began finding issues with gravel in the mains near Shasta Beverage and Costco. Cleaning efforts on February 17, 2016 of the sewer main in APE, just downstream of Shasta, have exposed a broken sewer pipe that prevents the current relining process to move forward without repairing the main by excavation and replacement. Attached is Mayor Ekberg's signed Emergency Declaration dated February 23, 2016 for the sewer main repair at 1200 Andover Park East. FISCAL IMPACT Since the emergency declaration was signed, staff requested quotes from nine contractors and received three submittals. The R.L. Alia Company submitted a cost of $114,219.46 (which includes a 20% contingency). The full extent of the damage to the sewer main can only be determined after exposing the failing pipe. The construction will be paid for from the 2015/2016 CBD Sanitary Sewer Rehabilitation Project funds, currently budgeted at $900,000.00 for 2016. RECOMMENDATION Council is being asked to approve the Resolution declaring an emergency for the repair of the sanitary sewer at 1200 Andover Park East and consider this item on the Consent Agenda at the March 21, 2016 Regular Meeting.

BACKGROUND The City has been implementing a phased rehabilitation of the sanitary sewer system in the Central Business District (CBD) since 2013. The sewer lines were originally installed in the 1960's and have served their effective lifespan. Rehabilitation or replacement is necessary to extend the service life of the sewer system. Visual inspections have revealed that certain segments of sewer main have deteriorated severely and multiple failures have occurred (see attached photos). The rehabilitation process must be carefully implemented as preparing the sewer mains for relining can cause additional damage and possible failure. The mains must be cleaned of debris before they can be relined and the process of high - pressure water cleaning can damage the sewer or even remove bedding adjacent to the sewer mains if a breach has already occurred. Some sewer mains have not been visually inspected due to inaccessibility of the inspection camera; therefore some pipe conditions are unknown. DISCUSSION Construction began in late January 2016 with initial relining efforts proceeding without incident. The Contractor began finding issues with gravel in the mains near Shasta and Costco. Cleaning efforts on February 16 of the sewer main in APE just downstream of the Shasta Corporation have exposed a collapsed pipe that prevents the current relining process to move forward without repairing the main by excavation and replacement. An emergency in accordance with TMC 2.57.030 and RCW 35.23.352 is requested in order to waive the standard bidding process. A Resolution will be prepared for Council approval at the next available Utilities Committee meeting date. FISCAL IMPACT At this time, repair costs are unknown. The extent of the damage can only be determined by exposing the failed sewer main. This work will be paid from the 2015/2016 CBD Sanitary Sewer Rehabilitation Project funds, currently budgeted at $900,000.00 for 2016. RECOMMENDATION Mayor is being asked to declare an emergency for the Sewer Repair at 1200 Andover Park East.

IMPACT: COMMENT: The asbestos concrete pipe in the CBD (commercial business district) is approximately 45 years old and becoming soft. Slip lining the pipe will reinforce the strength with little impact to roadways and minimal excavation. If the pipe collapses, the street will have to be excavated and the cost of the repairs will be significant. In the last five years we have had two major pipe failures on Andover Park West. A Public Works Trust Fund loan was successfully obtained in 2012 for construction. Reduced maintenance and repair costs. The limits of the 2013 project is APW to APE from Minkler Blvd to S 180th St and will now include the repair to the sewer under the railroad tracks.
