Home My WebLink About7 Bridge Street Tank TDPUD STAFF REPDt�T May 11, 2001 i To: Board of Directors From: Neil Kaufman Subject: Construction of Bridge Street 6160 Tank, Phase 1 AGENDA # At the past Strategic Planning meeting, Ed Taylor discussed the need for the District to bring a number of developers together, along with the District in order to construct some of the upcoming infrastructure projects. More recently, Ed discussed this issue at a Board Meeting in regards to the area northeast of downtown Truckee. Figure 1 shows the upcoming projects in this area. The Woodlands project is currently under development and the Pioneer Commerce Center will likely start within the next two months. The other projects will likely start construction either this fall or next spring. The existing water system infrastructure is inadequate to serve these projects. The Water Master Plan identified that creation of a new pressure zone with a hydraulic grade line of 6160 feet is necessary to serve this area. The proposed service area of this pressure zone is given in Figure 2. The Master Plan identified the need for a total of 3.6 million gallons of storage in this pressure zone at buildout conditions. The site for this storage was identified as the 129 acres of land acquired from Steele Family Partners. A conceptual piping network was also laid out and is shown on Figure 3. It is proposed that the 3.6 million gallons storage be provided in two separate tanks located adjacent to each other. Two tanks at the same site provides the District with a number of advantages: 1) One tank can be taken out of service for maintenance (painting, cleaning, etc.) while the other remains in service. 2) During periods of low demand (winter), one tank can be taken out of service to provide better water quality. 3) Allows for phased construction and would given the District the opportunity to better match actual system needs. Ed, Peter and I have been meeting with developers and the School District regarding the needed infrastructure. The projects shown on Figure 1 have a need for about 2.3 million gallons of storage upon completion (See attached Table 1). It is proposed that a 1.5 million gallon tank be constructed as the first phase. A tank of this size would provide adequate storage for the initial phases of the projects described. The second tank would likely be required within the next 3 to 5 years, depending on how quickly the projects reach full buildout. Ed believes that it is in the District's best interest that the District undertake the design and construction of the tank directly, as opposed having a developer construct the project. Please note that four existing District customers will be served from this new tank. Therefore, It is my opinion that the District is responsible for a small portion of the cost of the storage tank. The 24-inch pipeline from the tank site to just south of the existing Sanders Well would be constructed by the developer of the Pioneer Commerce Center. A reimbursement agreement would be written for this pipeline. The pipe size required for the developer projects is 16-Inch diameter. The rationale for a 24-inch pipeline is to provide the ability to move the water from four (or more) anticipated wells from the eastern portion of the service area to the western portion of the service area. It is my opinion that the District is responsible for the additional cost incurred to upsize the pipeline from 16-inch to 24-inch. The budget level cost estimate for the storage tank and 24-inch pipeline is given in Table 2. Recommendation: • The Board approve the proposal from Sauers Engineering for professional services related to the storage tank site and the 24-inch pipeline located on District-owned property. The proposed fee is $84,500. • I anticipate returning to the June 20 Board meeting with a request to Advertise for Bids Table 1.
