BACKGROUND In 1995, the City of Tukwila constructed the North Hill Reservoir. The reservoir is currently connected to all but three areas of the City. The Crystal Springs, Ryan Hill, and Duwamish Oxbow neighborhoods are directly connected to the SPU service mains and are isolated by freeways preventing them from being connected to Tukwila's North Hill Reservoir, These three areas also have a limited number of water service connections. DISCUSSION The Washington State Department of Health (DOH) is no longer allowing the City of Tukwila to use the 3 major SPU pipe lines that traverse the City to count as storage of water for domestic and fire /standby use. At a City of Tukwila Public Works staff meeting with DOH in November 2013, DOH stated that the Tukwila City Council could approve a policy by resolution setting the minimum of number of water service connections before a storage reservoir is required. FINANCIAL IMPACT The cost of each water reservoir to service these areas, depending on the location and land costs, would range from $750,000.00 to $1,000,000.00. RECOMMENDATION Council is being asked to approve the resolution that will set the minimum number of water service connections before storage reservoirs are required by the City and consider this item under New Business at the March 17, 2014 Regular Meeting.

Section 2. Storage of Domestic and Fire /Standby Water Policy.

PRESENTATIONS No presentations. II. BUSINESS AGENDA A. Resolution: Setting Policy for the Storage of Domestic and Fire /Standby Water Staff is seeking Council approval of a resolution that would establish a policy to not provide for the storage of domestic and fire /standby water in certain areas of the City with limited water service connections that are served directly from Seattle Public Utilities (SPU). The City's North Hill Reservoir is connected to all areas except for the Crystal Springs, Ryan Hill, and Duwamish Oxbow neighborhoods, due to their geographic relationship to freeways. These areas are instead directly connected to SPU service mains and have a limited number of connections. Maps of the three affected areas were distributed to the Committee. The Washington State Department of Health (DOH) has responded with comments on Tukwila's Supply Plan to disallow the use of three major SPU pipelines for storage of water for domestic and fire /standby use. DOH recommended that Tukwila City Council establish policy setting the minimum number of water service connections before a costly storage reservoir is required. The proposed resolution states that any water system zones serving 200 connections or less will not be provided storage capacity for domestic and fire /standby water as long as acceptable levels of supply redundancies exist. Supply redundancies are a result of interties, or systems of pipes that are served by other water purveyors that can be opened in the case of emergency. Staff confirmed that the three areas affected by this policy benefit from a robust intertie system which meets the condition stated in the proposal. Councilmember Ekberg asked if the affected neighborhood locations could be named in the resolution. Staff suggested that the appropriate place for this clarification is an appendix added to the Comprehensive Plan. UNANIMOUS APPROVAL. FORWARD TO MARCH 17, 2014 REGULAR MEETING UNDER NEW BUSINESS.
