WHY THIS MATTER IS BEFORE THE BOARD This item is informational. The Water Department intends to construct the District Pipeline Replacement - 2015 project during the summer of 2015. 2. HISTORY The Water Department has an ongoing need to replace existing water pipelines that fall into two basic categories. 1) Pipes that are in poor condition and require repeated repairs. 2) Pipes that are old, undersized (typically 4-inch diameter and smaller) and have exceeded their useful life. Historically, the District has undertaken an annual pipeline replacement project. In 2014, the pipeline replacement project involved replacement of about 4,350 feet of pipe at eight locations throughout Truckee. 3. NEW INFORMATION The scope of District Pipeline Replacement - 2015 project has been finalized and the contract documents are essentially complete. The project covers about 4,900 feet of pipeline along three segments in Tahoe Donner. Figure 1 shows the planned replacement work. Listed below are the planned pipeline segments. Northwoods Boulevard from Viking Way to Norse Avenue Northwoods Boulevard from Christie Lane to Davos Drive Northwoods Boulevard at Swiss Lane The Town of Truckee is undertaking a three-year project to repave Northwoods Boulevard. The portion from Donner Pass Road to the flashing red signal was repaved in 2014. The northern portion of the Northwoods Loop from the flashing red signal to Fjord Road will be repaved in 2015 with the remaining southern portion of the loop planned for 2016. The pipeline replacement work is located on the southern portion of the loop and should be completed before the Town repaves the roadway. As discussed at previous workshops, the District’s overall communications plan calls for the installation of a fiber optic cable network to link all of the District’s remote facilities together. This network will have greater speed and reliability than the existing radio systems. Michael D. Holley General Manager / Water Utility Manager The District has miles of inactive water pipelines that have been replaced over the years. The District believes that utilizing some of these inactive water pipes as conduits could result in a significant cost savings for installation of the fiber optic network. Therefore, the installation of about 7,800 feet of inner duct along with pull boxes and pole risers for two segments of Northwoods Boulevard has been included in the pipeline project as a test case. These locations are shown on Figure 2. These facilities will allow the installation of the fiber optic cable at a future date without having to disturb the newly paved roadway. The current project schedule is: Begin Advertising for Bids - February 2015 Bid Opening - End of March 2015 Bid Award - April 2015 Begin Construction - May 2015 Complete Construction - October 2015 In addition to the construction contract, the District will retain outside consultants to perform geotechnical testing, surveying and environmental services during the construction period. 4. FISCAL IMPACT The Water Department has allocated about $1,200,000 for the pipeline replacement work. The planned funding source for this project is the Water Department Capital Replacement Fund. The Electric Department has allocated about $200,000 for the inner duct, pull boxes and risers. The planned funding source for this project is the Electric Department General Fund. 5.
