HomeMy WebLinkAbout10 Pipeline CEQA Approval - Boardo TRUCKEE DONNER Public Utility District MEETING DATE: May 4, 2022 TO: Board of Directors FROM: Neil Kaufman, Water System Engineer Chad J. Reed, Water Utility Director AGENDA ITEM #10 SUBJECT: Consideration of Approving the CEQA Initial Study/Mitigated Negative Declaration for the Pioneer Trail Pipeline and Pump Station Project I_1»00]TLI :1911-YA RECOMMENDATION: Approve the CEQA Initial Study/Mitigated Pipeline and Pump Station Project Brian C. Wright, General Manager Negative Declaration for the Pioneer Trail DISCUSSION: The Tahoe Donner subdivision consists of approximately 5,600 single family homes, about 400 multi -family residential units, a golf course, downhill ski area, cross-country ski area and other amenities. The subdivision represents approximately 44% of the water system customers. An additional 500 residential units are expected in the Tahoe Donner area at buildout conditions. The entire subdivision is served by a single 14" welded steel pipeline with two pump stations and two storage tanks that essentially serve as forebays. These facilities were constructed in the early 1970s and are approaching the end of their useful life. The District previously identified the need to construct a second pipeline into Tahoe Donner and this project was discussed in the current Water System Master Plan. The master plan identified the need for a 20" pipeline, but more recent estimates of buildout water demand have determined that the pipeline can be downsized to 16" diameter. Page 1 of 3 On the eastern end, the new pipeline will connect to an existing 24" pipe near Pioneer Trail and Comstock Drive. The western end will connect to an existing 16" pipe at the intersection of Northwoods Boulevard and Lamplighter Way. It is currently planned to install electrical and communications conduits in a joint trench with the water pipeline. A new pump station will be needed to lift water into the Tahoe Donner area. The planned location for the pump station is on District -owned property in close proximity to the TNT Materials concrete batch plant. It is planned to break the project into two separate construction contracts — one covering the pump station and the other covering the pipeline and conduits. The Board previously awarded three contracts with outside consulting firms associated with this project: • In November 2020, a contract was awarded Water Works Engineers (WWE) to provide design assistance with the crossing of Trout Creek and performance of a hydraulic transient analysis. • In October 2021, a contract was awarded to Sauers Engineering to design the pump station. • In October 2021, a contract was awarded to Helix Environmental Consulting to perform the environmental review of the project. Helix has completed the environmental review and determined that a mitigated negative declaration was appropriate. The CEQA Initial Study/Mitigated Negative Declaration (IS/MND) was made public on March 12, 2022 and the public comment period closed on April 12, 2022. The District received one comment regarding the project from the United Auburn Indian Community (UAIC). UAIC requested that language be included in the IS/MND regarding any unanticipated discovery of potential tribal cultural resources. Language regarding this issue had already been included in the IS/MND. On April 18, the District began advertising for bids for the pipeline construction contract. The bid opening is scheduled for May 19, and it is expected that a recommendation for award will be presented at the June 1 Board meeting. Sauers Engineering is continuing to work on the design of pump station. It is expected that advertising for bids will begin in the middle of May 2022 and that a recommendation for award of the construction contract will be presented at the July 6 Board meeting.
