WATER Public Works has analyzed the needs of the water enterprise fund. Cascade Water Alliance's (CWA) wholesale water rates are projected to increase 6.2% for 2013. A rate increase on the minimum water meter charge (see Table 1) is being proposed for residential and multi family customers to maintain the current level of service and lessen the impact of future increases for purchased water. Increases are also proposed for consumption charges for multi family and commercial /industrial rates. Exhibit A is a rate matrix of all of the proposed utility rate increases for residential customers. Exhibit C -1 shows a comparison of adjoining cities and their water rates. Exhibit D is the Resolution which updates the Public Works Fee Schedule. SEWER King County Ordinance No. 17343 has a 10.22% sewer rate increase for King County sewage disposal fees in 2013. The sewer rate will increase from $36.10 to $39.79 per residential customer equivalent per month. The King County sewage treatment capacity charge (for any new sewer connections) will increase from the current $51.95 to $53.50 per month for fifteen years for any sewer connection occurring between January 1, 2013 and December 31, 2013. Exhibit B is King County Ordinance No. 17343. Tukwila's sewer base rate is scheduled for an increase (see Table 2) in accordance with the rate model which analyzes the City's operational and capital needs. The City's sewer rate will increase from $19.26 to $23.10 per residential connection and from $33.74 to $40.48 for up to 750 cubic feet or fraction thereof for commercial /industrial customers. Exhibit C -1 shows a comparison of adjoining cities and their sewer rates. SURFACE WATER Tukwila's surface water base rate is scheduled for an increase in 2013. The City's surface water rate will increase from $102.00 to $107.00 per residential parcel, per year and will range from $12.92 to $108.04 per 4,356 square foot for all other parcels. Exhibit C -2 shows a comparison with other cities and their surface water rates. 15 INFORMATIONAL MEMO Page 2 i!

BACKGROUND In 2010 the City contracted with Carollo Engineers to update the Water Comprehensive Plan. DISCUSSION For the 2005 Comprehensive Water Plan, the Washington State Department of Health (DOH) required no additional storage of water in lieu of the existing 2 million gallon reservoir and multiple taps off Seattle pipelines. In 2009, DOH guidelines were revised to require standby storage of water at 200 gallons per equivalent residential unit (ERU). With the 2009 DOH storage guidelines, the existing Tukwila 2 million gallon reservoir is now undersized for the current population of the city. With the projected 2030 population growth model provided by the Tukwila Department of Community Development (DCD), the condition worsens. Initially, Carollo Engineers used the 2010 -2030 population data study from Puget Sound Regional Council (PSRC), as provided by DCD, to determine the required reservoir size to meet the revised requirements from DOH. Using the PSRC 2030 population model, the City of Tukwila would be required to construct a new reservoir to bring the City's total water storage to 7.1 million gallons with a design and construction cost for the proposed reservoir at over $5.5 million dollars. This cost estimate does not include the cost of land acquisition for the reservoir and a necessary pump station. The total cost of the project could be over $10 million dollars for the reservoir, pump station, and land. With the high cost of the required water reservoir and other water CIP improvements, Public Works questioned DCD on the projected 2030 population growth model for the City. It was agreed that the 2030 PSRC model used for population forecasting overstates projected growth within the City. For the Comprehensive Water Plan, DCD agreed to cut the projected growth in half by changing the time period from 2010 -2030 to 2010 -2040. With a reduced population growth, the total reservoir requirement of 7.1 million gallons can be reduced to 4 to 5 million gallons of total storage. The reduction in reservoir size results in savings to the City of several million dollars in costs to the Water Fund. Carollo Engineers additional work will modify the Water Comprehensive Plan. The supplement will focus on updating the revised growth projections with the new 2012 data 39 Info Memo Page 2 Carollo Engineers Supplement No. 3 developed by DCD. The reduced growth projections will be used to calculate new average and maximum day water demand for future planning scenarios. The new demand will be updated in the supply analysis, hydraulic modeling analysis, and storage analysis. The system will be evaluated to determine the deficiencies and proposed improvements needed with the new demand in each service area. It is anticipated that this will also modify the proposed improvements in the CIP and this new data will modify most sections of the Water Comp Plan. FINANCIAL IMPACT Supplemental Agreement No. 3 will increase the consultant's scope of work for Task 300 Planning Considerations for $16,250.00. Funding for the additional work will come from the Interurban Water Reuse Project, page 86 of the 2012 CIP at $25,000.00 and Andover Park West Water Line Project for $16,000.00, which will now be constructed in 2013.

CITY OF TUKWILA Jim Haggerton, Mayor CONSULTANT By: Lara Kammereck, Associate Vice President 41 42 gLty of Tukwila Jim Haggerton, Mayor TO f3tm M DATE: October 19, 2012 SUBJECT: Surface Water Comprehensive Plan Project No. 91041202 Draft Comprehensive Plan for Review Chapters 1 4 ISSUE Present Chapters 1 4 of the proposed 2012 Surface Water Comprehensive Plan. BACKGROUND The City hired CH21VI Hill to update our Surface Water Comprehensive Plan (SWCP) to reflect changes in regulatory requirements and drainage needs within the City. The current SWCP was completed in 2003 and does not reflect changes in regulations required under the City's National Pollutant Discharge Elimination System Permit, our current GIS inventory, completed CIP projects, the Tukwila South annexation area, nor newly identified needs. DISCUSSION Staff intends to review the draft SWCP in a series of three Utilities Committee meetings. The first meeting reviewed the proposed changes to the CIP projects. This second review will concentrate on a page by page review of Chapters 1 4. The third meeting will review the remainder of the Surface Water Comprehensive Plan. Staff will then complete a final draft, obtain a SEPA determination, and bring the SWCP forward for final review and Council approval by resolution. RECOMMENDATION Information only. 43
