DATED this day of , 20 CITY OF TUKWILA CONSUL ANT By: Mayor, Jim Haggerton Printed Name: Title: jilj T Attest /Authenticated: Approved as to Form: City Clerk, Christy O'Flaherty Office of the City Attorney CA revised : 1 -2013 Page 5 17 18 ORIGINAL f PAGE NO (f) OF 14—PAGES AGES EXHIBIT A Scope of Work City of Tukwila 2013 Central Business District Sewer Rehabilitation March 2013 BACKGROUND The portion of Tukwila's Central Business District (CBD) for this project is bounded on the north by Minkler Boulevard, by South 180th Street on the south, and by Andover Park East and Andover Park West to the east and west, respectively. This area was first developed in 1967 by the Sammamish Commercial Company as an industrial park warehousing area. The developer installed asbestos - concrete (AC) pipe for the sanitary sewer system. The design life of AC pipe is 40 years, and the existing pipe has begun to fail. In 2007 and 2011, the sanitary sewer system in the areas of the City of Tukwila (City) experienced collapsed pipes due to the age and condition of the pipes. The repair of the collapsed pipe in those years cost the. City over $500,000 due to the depth of the pipe and seasonal high groundwater. To prevent the collapse of any more sewer pipes in this area of the CBD, which would be likely to result in the discharge of sewage into the Green River, the City has decided that the sanitary sewers in this area of the City need rehabilitation by lining with cured -in- place -pipe (CIPP). There is approximately 3,500 feet of 8 -inch diameter and 4,000 feet of 12 -inch diameter gravity sewer main that has been identified for lining. Additionally, approximately 10 manholes that have sustained corrosion are to be lined with cementitious coatings. Improvements made as part of this project are focused primarily on the structural rehabilitation of the pipe and manholes and secondarily on inflow and infiltration control. The City has received a Public Works Trust Fund loan for this work. The City has not had hydraulic capacity problems with the sewer in this area. The area is fully developed at the present time. In HDR's 2005 Comprehensive Sanitary Sewer Plan Conveyance System Analysis, computer hydraulic modeling found all the pipes were at less than 60- percent capacity. If the pipes were relined, there could be a small reduction in capacity of the pipes, but the coefficient of friction will be reduced, due to the smooth inside surface of the new pipe offsetting the reduced inside diameter. CIPP was chosen as the preferred rehabilitation method because it costs less than open -cut replacement or pipe bursting while still maintaining the needed conveyance capacity. Another component of work to be included in the project is the installation of a new manhole in the existing sewer in the 300 block of Andover Park East. Currently the distance between manholes in this block is 600 feet, which is 200 feet longer than the maximum spacing recommended by the Washington State Department of Ecology's Guidelines for Sewerage Works Design. The City has attempted to install a manhole in this area once already, but prolific groundwater and running sands threatened the stability of the excavation. The City abandoned the attempt and will now approach the project with a geologic exploration and development of a dewatering and shoring plan prior to construction. Included in this scope is the hydrogeologic analysis followed by preparation of design and bidding documents for the new manhole installation. This Scope of Work describes engineering services for the City of Tukwila's 2013 Central Business District (CBD) Sewer Rehabilitation project. 1 08/30/12 J.A Data \?UK \ SR) \2012 Rehabilitanon of Sanitary Sewer in the Area of Tukwila's Central Burin ess District Proposal /Contract \PSA_SG \ti_TUK_2013 CBD Sewer RehabBiraron.d 19 20 City of Tukwila 2013 Central Business District Sewer Rehabilitation OPIGINAL I PAGE NO 1 OF I +PAGES Exhibit A Scope of Work The work will be performed under the following Tasks: 1.

Resolution Declaring Emergency: Andover Park West /Andover Park East Sewer Repair — March 2013 Staff is seeking Council approval of a resolution declaring an emergency and authorizing a contract exempt from competitive bidding for the immediate stabilization of a damaged sewer system between Andover Park West (APW) and Andover Park East (APE) near Minkler Boulevard. This section of sewer pipe has failed two times within the last two years. The current resolution will allow City staff to provide a temporary stabilization of the sewer pipe so that a long -term repair project can be designed and constructed through the City's regular bidding process. The cost of the temporary pump rental and pumping is $40,000 for four months. UNANIMOUS APPROVAL. FORWARD TO MARCH 25 COW FOR DISCUSSION. B. Commercial Business District (CBD) Sanitary Sewer Rehabilitation — Consultant Agreement Staff is seeking Council approval of a consultant agreement with RH2 Engineers for design services relating to the CBD Sanitary Sewer Rehabilitation Project in the amount of $79,977. This project is funded in part by the obligated 2012 Public Works Trust Fund (PWTF) loan of $750,000. We believe that part of the PWTF will be able to aid the emergency repair project listed above as it is in the same area. Committee questioned the scoring of the consultants as there were only two applicants, and staff did not include a scoring worksheet in the packet. UNANIMOUS APPROVAL. FORWARD TO APRIL 1 CONSENT AGENDA. C. NPDES Program: 2013 Surface Water Management Program and 2012 Annual Report As a requirement of the National Pollutant Discharge and Elimination System (NPDES) Phase 11 permit, staff has completed the 2013 update to the Surface Water Management Program (SWMP) as well as the 2012 Surface Water Management Annual Report. Both documents must be submitted to the Department of Ecology (DOE) by March 31, 2013. As of August 1, 2013, an updated NPDES Permit Phase I1 will be in effect. The City's current NPDES Permit expired February 15, 2012, was extended by DOE for one year (system- wide), and will be replaced with an updated Permit that will be valid August 1, 2013 through July 31, 2018. Staff reviewed the new NPDES requirements which go into effect on August 1, 2013. Included in the requirements is the option to either pay for Regional Monitoring (cost $4k) and Effectiveness Studies (cost $7k) conducted by DOE or conduct monitoring ourselves. Low Impact Development (another LID) is a NPDES requirement that includes using pervious surfaces that could be pavers, rain gardens, and porous asphalt and concrete. Some developers are submitting LIDs with their plans, but nothing will be required until 2016. INFORMATION ONLY. 31
