BACKGROUND KPG, Inc., of Seattle, Washington, and the City of Tukwila entered into Contract No. 05-040 for preliminary engineering and design services for the 2005/2006 Small Drainage Program. The initial contract amount was $176,683.00. A contract supplement (Supplemental Agreement No 1) in the amount of $48,574.12 was approved for construction engineering services for the 2005 construction contract. Following last winter's heavy rains and flooding, seven additional projects were identified for construction as soon as practical. Five of the projects involve failing outfalls to the river, one is to remove a failing driveway culvert on Southgate Creek, and the seventh involves the removal of a failing concrete pond in Crystal Springs Park. The park design and future construction project will be funded through 301 funds. ANALYSIS Two of the five failing outfalls are within the Tukwila 205 Levee. These outfalls are a critical component of the flood control system and must be corrected before the next flood season per Tukwila agreement with the U.S. Anny Corps. The failing driveway culvert on Southgate Creek could completely fail, blocking downstream drainage structures and lead to significant flooding. All of the projects will require various permits through the Anny Corps, the Department of Fish and Wildlife Services, and the City of Tukwila. A contract supplement for design services has been negotiated for a fixed fee not to exceed $77,469.49. This amount is within the overall Neighborhood Drainage Project budget. RECOMMENDATION Authorize the Mayor to sign Supplemental Agreement No.2 to Contract No. 05-040 with KPG, Inc., in the amount of $77,469.49 for a new contract total of $302,726.29 attachment: Supplemental Agreement No.2 (p:Projc<<sIA- DR Projeas\05DROIIJ)es;gn\Infu Memo KPG Supp No.2) Remove failing culvert embankment 2005-2006 Annua\ Neighborhood Drainage Program Supplement No.2 - 2006 Sensitive Area Projects Outfall #3 Outfall #2 failing concrete tank- crystal Springs Park ~ SUPPLEMENTAL AGREEMENT No.2 CONTRACT No. 05-040 PROJECT No. 05-DROl City of Tukwila Public Works Department 6300 Southcenter Boulevard #100 Tukwila, WA 98199 KPG, Inc. 753 - 9th Avenue N.

Reore:anization of Public Works With the resignation of Al Spencer, Public Works has been provided an opportunity to reorganize the George Long Shops. The proposal is to eliminate the Internal Operations Manager's position, elevate the current Facilities and Fleet Supervisors to the Superintendent level and have them report directly to Pat Brodin. Public Works would add a Fleet Technician to meet the growing demand of the City's aging fleet and improve the perfonnance goals in Equipment Rental. The number of full-time employees would remain the same and there \would be a reduction in salary costs. The salaries listed do not include benefits, as there was no change in the number of employees, so the benefits are approximately the same. Unanimous approval of staff reore:anization from Committee. no action is needed by Council. so not forwarded to full Council. B. New Drinkine: Water Requirements form the USEP A The EP A has now mandated that we must monitor for disinfectants even though the City purchases all of its water. Additionally, all purchased water has been pretreated. We will need a plan and modeling on our water flows and where it goes. Pam L suggested we have an article in the Hazelnut on unfunded mandates and the running total. Pat said that it would be included in the City's annual water confidence report and we could put an article in the Hazelnut about water and the new unfunded mandates. The item will return to Committee when we have negotiated a contract for the plan with a consultant and costs. The estimate is $70,000 to set up the program and approximately $20-30,000 a year thereafter. Information Only. C. Table 9 Water Customers - Cross Connection Control The water department is also required to insure that all "high risk" commercial or industrial water accounts have installed a backflow device to isolate the public water system. If the water is able to flow back into the water main, it could contaminate the water supply. Each year the State becomes more stringent. Last year we updated all of the sewer pump stations and this year the State is including dental offices. All buildings with sprinkler systems, irrigation and laboratories are isolated and have the backflow device, preferably at the water meter. The first step is the letter that is mailed out, and if the owners do not co~ply, we are able to cite them and could ultimately shut off the water. Information Only. t D. 2005/2006 Small Drainae:e Proe:ram Desim Supplement We have KPG currently under contract to design the 2005/2006 Small Drainage Program. This winter seven sites were found that need to be repaired as soon as practical. Two outfalls along the levee and upon further inspection three more failing outfalls were found. Also included are the Crystal Springs concrete water pond that is leaking and the Robertson driveway culvert. The current projects under design will be put on hold, so the design funds budgeted in 2006 will be available for this supplement. Unanimous ae:reement to send recommendation for desim supplement with KPG to COW and Rel!lllar meetine: for approval.
